202 1 summary report of mechanical designer's work 1
The 20__ year is coming to an end, and the footsteps of the 20__ year have come to us gently. Looking back on the past six months in _ _ company, there are joy and loss, sweat and tears of excitement. I walked out of the university's ivory tower under the scorching sun in July and gradually integrated into the company's safe, frank and excellent working atmosphere. We are growing and the company is making progress. I am willing to exchange my efforts for greater development of the company!
On July 30th, 20__, with the end of the ten-day corporate culture and occupational health education and training for new employees in _ _ head office, I was assigned to _ _ installation company, and then we entered the intense training and study. After all, nuclear power is something only a few people can understand. For those of us who just entered the company, there are both worries and puzzles. What is the working principle of nuclear power? Will our work be exposed to nuclear radiation in the future? These problems are bothering us.
From August 1 to September 4th, we conducted a month of basic nuclear power training. Understand the development history and present situation of nuclear power in China, and more deeply understand the necessity of developing nuclear power in China in the future. When the old staff gave lectures, we listened attentively. They carefully prepared lessons and made vivid courseware, which let us know some basic knowledge about nuclear power installation and what our company will do in C3C4 nuclear power plant.
Although the nuclear power installation company has just been established, I believe that the future nuclear power installation company will be more exciting with the careful preparation of the old employees, the strong support of the leaders of the head office and the concerted efforts of our employee Qi Xin's Qi Xin!
Then he was assigned to Tongliao project department of coal chemical industry of _ _ company and started his own internship process. My major is water supply and drainage engineering technology. At school, I focused on municipal engineering. I was shocked when I first came to Tongliao Project Department. Industrial pipelines support the production of factories like human blood vessels. I asked myself silently, "Can I cope with the work at hand in the future?"
At first, I was assigned to the following team to help the workers. Although it was a little hard, I gradually became familiar with the environment and learned to change. Suddenly, I feel that the pipes are actually the same, but we are timid in the face of strange things, and I have gradually adapted to it and started to experience and summarize something. In the field work, I know how to assemble the pipeline, the general process of pipeline installation, and how to use the manual hoist. What shocked me once was that a stainless steel pipe DN400× 12 was successfully positioned in the pipe gallery under the lifting of a manual hoist.
I also learned some common tools, such as ring spanner, plasma cutting machine, adjustable wrench and so on. I also actually operated a grinder and a plasma cutting machine. I know what argon arc welding is and what argon arc welding is.
In June 5438+10, the civil engineering of the new esterification reconstruction project was handed over smoothly, and I was sent to another group as a material engineer. If the field work in September made me understand the workflow, then this responsibility made me really understand what we need in construction and what is the difference between various pipes and fittings. In the process of obtaining materials, I learned that there are flat welded flanges, flat welded flanges with necks, welded flanges with necks, and flat, convex, concave-convex and tenon-groove surfaces.
I also know gate valves, globe valves, pneumatic valves, quick-opening ball valves, oxygen valves, socket welded gate valves, filters, flame arresters and other valves. I know that flange gasket includes winding gasket, asbestos gasket and tetrafluoroethylene gasket. In this process, I also understand some common sense in pipeline construction. For example, when the pipeline meets equipment, the flange should be installed on the equipment first, and then the pipeline should be hoisted for welding. This month's practice has taught me a lot and solved many doubts in my heart.
Although I haven't changed teams since I came to Tongliao Project Department, because the new esterification transformation project is relatively small, I also know something about mechanical and electrical teams. During the esterification transformation, the mechanical group and I participated in witnessing the hoisting of the new ester tower, as shown in the following figure:
I once went to a workshop with the mechanical group to calibrate a pump coupling. These experiences have given me a preliminary understanding of the work that other majors should be responsible for in installation engineering.
In June165438+1October, with the overhaul basically over, the project department gradually transferred to the factory to carry out some sporadic technical transformation work, and the pipeline technician also went back to visit relatives while the project was not tight, so I acted as a technician for a few days. Although they are all small jobs, I dare not take them lightly. Always take the initiative to communicate with Party A, and help master workers to open electricity and fire tickets. In this series of small work exercises, I understand what a technician should do.
First of all, we should communicate well with Party A, truly understand Party A's construction intention, and put forward our own rationalization suggestions to facilitate workers' construction; Secondly, when communicating the construction contents with Party A at the site, plan the required materials in advance so as to carry out the construction quickly and effectively; Third, communicate with the workers, make technical disclosure, and explain some safety precautions at the workers' site to ensure the smooth completion of the project.
In addition, I have witnessed several emergency maintenance tasks. Although it is hard to work overtime at night, I learned how to carry out the work and how to deploy personnel from the emergency repair. The above experience is just beginning, and I believe I will be more handy with the growth of experience.
65438+February, with the coming of winter, the project basically ended, and I also started the year-end data sorting work of the project department. Under the guidance of the technical manager of the project department, I sorted out the workload of some small jobs I was responsible for in the previous stage and accompanied Party A's personnel to conduct on-site audit. I am glad to see the fruits of my labor.
At work, I also found something I didn't learn, such as the application of measurement in installation. Because it is a technical renovation project, the pipeline installation is basically dimensionless, and the workers measure their own dimensions and then prefabricate and install them. I don't think this will happen in nuclear power installation, especially in new projects. As a technician, I hope to master some measurement knowledge in the future, so I think this aspect is lacking in my work in the past six months.
Looking back on the past six months, I feel that I really started working. At work, I actively learn from the master, but also restless to understand the workflow principles of other majors. Although I have learned something, I understand that our final project is the installation of nuclear power plants, which will be more complicated and systematic, and I still have a lot to learn. In the new year, I will continue to maintain my enthusiasm for work, do a good job at hand, and accept the company's future nuclear power installation tasks with a good face.

I. Work experience
I have heard that mechanical work is very tiring and workers are very hard. After coming to the company, I felt the hard work of my colleagues. In _ _, my colleagues used four special words to describe them: special efforts, special dedication and special patience. Colleagues travel abroad for three seasons all year round, so they can't take care of their parents, wives and children. They work hard and never complain. This spirit of selfless dedication is something I must learn. In the communication with workers, I learned how to face difficulties, how to be a man, and established a correct outlook on life and values. Whether it is on-site installation and debugging or in-company equipment, the requirements for equipment quality are getting higher and higher, and technicians must strictly control it, especially the management and mandatory provisions of low-old and bad problems. After three years of work and study, I feel that as a technician, I must be careful and conscientious, do every step of work well, be familiar with process flow, drawings and specifications, constantly learn engineering-related and professional-related knowledge, and arm myself with knowledge. This is another year of ups and downs in my work. Every time the company gives me an opportunity, it is a kind of trust, a test and an exercise for me. Indeed, born in sorrow, died in happiness. In today's fierce competition, it forces you to study, stand on your own feet, challenge yourself and adapt to the high demands of others. Only on this tight string can we feel the fullness, richness and significance of life. I soon mastered the method of mechanical work. Only when people really understand the great works of thought will the environment not be an excuse for failure.
I learned a lot from my work, which added more motivation to my future work. I like our company's fighting spirit of "starting from scratch and pursuing perfection". This is what a person should do. Only by starting from every little thing can we accumulate more experience, and setbacks and failures in our work are inevitable. As long as we face it frankly, we will learn a lot from it. People who can't stand setbacks can't do a good job. Because everything can't be arbitrary, there are some things behind success and failure. Our technical service personnel should sum up more experience from the process of various diseases and really serve users well. At the same time, in the process of work, we can feel the company's concern and expectation for us, so everyone should try their best to do their own job and contribute to the company's development.
Second, the ideological experience
_ _ was the first year when I really started working. Everyone has different understanding and feelings about work or career, so do I. For me, I usually grasp my own ideological context from two angles.
The first is mentality. To paraphrase a famous saying, "Attitude is everything", only with the right attitude can we find the right direction and get the right result in the right way. Specifically, my attitude towards work is to choose what I like and then do my best for what I love. I have always believed that work should not be a task or a burden, but a pleasure and enjoyment. Only when you are interested in it and fall in love with it completely can you fully appreciate this happiness. I believe that I will find the pleasure of working in the process of trying to explore and discover this business, and I can do my best for it without reservation. It can be said that only when you know how to enjoy your work can you know how to succeed, and you can't be forced during the period.
Secondly, the problem of ability, which can be divided into professional ability and basic ability. I can use a simple example to illustrate my understanding of this problem: as far as camel is concerned, professional ability determines how long it can survive in desert environment, while basic ability, including adaptability, perseverance and natural vigilance, determines how long it can survive in desert environment. Specific to people, professional ability determines whether you are suitable for a job, and basic abilities, including cooperation ability, ability to take responsibility, adventurous spirit and development potential, will directly determine the vitality of the job. A successful person in his career must be a person whose two abilities can develop and operate harmoniously. In _ _ _ years, I once put myself into my work with a brand-new mental state, studied hard, improved my working ability, actively responded to the company's measures to strengthen management, and abided by the company's rules and regulations. Although I have made some achievements in less than one year's working time, there are still many problems in my work, mainly as follows:
1, lack of innovative spirit
Can't take the initiative to play their own ability, passively adapt to the needs of the work, the business volume can be basically completed, but they can't take the initiative to lead the work, so they are passive, so they lost some opportunities and the work did not rise to a certain height.
2, the work is not very solid
There are some problems, such as being too arrogant and lazy. I can't concentrate on work and study. Although I know a lot of knowledge, I am not good at it. I can't take the initiative to speak in company training, and I haven't completely let myself go.
This is a summary of my work over the past year, so I won't say much. But I think it is more convincing to do it with practical actions. So I will work hard in the future and continue to consolidate the existing achievements.

_ _ Company is a research and development enterprise which mainly produces transformer equipment. It is currently a domestic transformer equipment manufacturer and an Asian electrical equipment manufacturer. The work of the production department is heavy and arduous, because it shoulders the task of assembly and on-site installation and debugging of all the equipment of the company. Under the guidance of workshop leaders and masters, I have better integrated into this tense and rigorous working atmosphere, successfully completed all the work arranged by the leaders, greatly improved my professional quality and working ability, and gained new confidence in my work. In the past three years, I have participated in the on-site installation and debugging of more products, equipment and equipment, from which I have benefited a lot. Not only have I learned a lot of professional knowledge, but also have a more comprehensive understanding and mastery of power equipment, and cultivated my basic qualities as a mechanical engineer. At the same time, study hard and insist on self-study to improve the theoretical level. The specific summary is as follows:
I. Work Performance in 20__ years
I am a college graduate who has just entered the society. I graduated from _ _ _ _ _ _ 20 years ago. I am a new employee, and my major is the design and manufacture of professional technical machinery and its automation course. First, attend the company's training. Understand the basic situation of the company, understand the basic work and tasks of working in the company. As a new employee, I also actively participated in other trainings organized by the company and learned a lot of knowledge and ideas that I had never been exposed to before. After I officially joined the company, at first, I felt that everything was at a loss, although I was a mechanical major. I only learned some theoretical knowledge at school, so there are few opportunities for practice. The workshop is a good place for me to study and practice. When I arrived at the workshop, I found that the theoretical knowledge I learned at school was too superficial and it was very difficult to work. At the construction site, I humbly ask the master, and I will ask if there is anything I don't understand. I seem to be busy with these equipment drawings. Only after I went to work did I know that I had little knowledge and had a lot to learn. Therefore, I humbly ask the master, ask more questions and look at more pictures. Based on my job, I'm afraid I won't ask if I don't learn. During my internship, due to my diligence and good guidance from my master, I got a basic understanding of the company's equipment. During the probation period, my job is mainly to assist the master in assembly and get spare parts from the warehouse. At the same time, I also know something about spare parts, and I know its effect on the whole equipment during assembly. In the assembly work, we can only do some basic work, such as tapping and drilling. Although these tasks seem unremarkable, they are also the basic efforts to do an assembly work. Therefore, I am also very attentive to these small tasks. If I can't do it well, I have to be reworked by others, which is also a waste of other people's working time.
While working, I also found that my mechanical drawing ability is not very good. Combined with work needs and personal actual situation, I focused on learning the relevant knowledge of autocad drawing. The basic skills of mechanical drawing have been greatly improved. This has brought great help to my future work.
Second, the performance of 20__
After more than a year's work, I have completed the complete transformation from school to society, abandoned those unrealistic ideas and devoted myself to my work. As my work became more and more handy, I began to think about how to make new achievements in my work in order to realize my own value. I have always been very active and don't want to fall behind. I keep telling myself: I must do everything well and go all out. Through this year's experience, I deeply realize that carefulness and preciseness are the qualities that should be possessed, while mastery, similarity and innovation are the key factors of mediocrity or Excellence.
Through this year's work practice, my mechanical knowledge and work have been greatly improved.

1. Lack of innovative spirit.
Can't take the initiative to play their own ability, can only passively adapt to the needs of the work. Basically can complete the business, but will not take the initiative to lead the work, so it is very passive. So I lost some opportunities and my work didn't rise to a certain height.
Second, the work is not very solid.
There are some problems, such as being too arrogant and lazy. I can't concentrate on work and study. Although I know a lot of knowledge, I am not good at it. You can't take the initiative to speak in company training, and you haven't completely let yourself go.
This is my summary of my work in the past year, so I won't say much. But I think it is more convincing to do it with practical actions. So I will work hard in the future, continue to consolidate the existing achievements, improve my own shortcomings, and strive for by going up one flight of stairs in the future work!
What I learned in Qiyuan is not only useful now, but also will benefit me for life. Thanks again to Qiyuan.
In short, in these four years, I have made great progress in both technology and management. In the future, on this basis, I will study hard and make persistent efforts to raise my work level to a higher level and contribute to the development of the company.

In the past year, I participated in more product design and benefited a lot from it. Not only have I learned a lot of professional knowledge, but also have a more comprehensive understanding and grasp of dynamic products, and cultivated my basic qualities as a mechanical engineer. At the same time, I insisted on self-study, learned new tools, software and professional books in the current mechanical industry, and improved my theoretical level. The specific work is summarized as follows:
The division of NC machining process can generally be carried out in the following ways:
(1) tool centralized sorting method is to divide the working procedure according to the tools used, and process all parts that can be completed with the same tool. Use the second knife and the third knife to complete other parts they can complete. This can reduce the number of tool changes, idle time and unnecessary positioning errors.
(2) For parts with more processing contents, the processed parts can be divided into several parts according to their structural characteristics, such as internal shape, external shape, curved surface or plane. Generally, the plane and positioning surface are processed first, and then the hole is processed; Machining simple geometric shapes first, and then machining complex geometric shapes; The parts with lower precision are processed first, and then the parts with higher precision requirements are processed.
(3) For parts that are prone to machining deformation, shape correction is needed due to possible deformation after rough machining, so generally speaking, the process should be rough machining and finish machining separately.
To sum up, when dividing the process, we must flexibly grasp the structure and manufacturability of parts, the function of machine tools, the content of NC machining of parts, the number of installations and the production organization of units. In addition, it is suggested to adopt the principle of centralized process or decentralized process, which should be determined according to the actual situation, but it must be reasonable.
The arrangement of machining sequence should be considered according to the structure and blank of the parts and the need of positioning and clamping, with the emphasis on not destroying the rigidity of the workpiece. Generally speaking, this order should be carried out according to the following principles:
(1) The machining of the previous procedure cannot affect the positioning and clamping of the next procedure, and the machining procedures of general machine tools should also be considered comprehensively.
(2) Add the inner cavity first, and then process the shape.
(3) Adopt the same positioning and clamping method or the same tool processing program to reduce the times of repeated positioning, tool changing and moving the platen.
(4) For multiple processes in the same installation, the process with little damage to the rigidity of the workpiece should be arranged first.
1, the basic requirements of mechanical design
A) Pay attention to the coordination and balance of the functional requirements of the machine! Prevent the emergence of barrel effect
B) Requirements for machine economy Design economy, put into production and put into market in a short time, recycle consumption during development, and even design and manufacture at the same time.
Cost-performance ratio is necessary for economic use (products are produced in small batches and then improved better)
2, the basic requirements of mechanical parts design
A) Work normally and reliably within a predetermined working period to ensure the functions of the machine;
B) Minimize the manufacturing cost of parts;
C) Use as many standard parts as possible;
D) For the products that may be serialized, the generality of parts should be considered as much as possible at the beginning of design, and the structures that are not universal should be similar as much as possible, so as to reduce the workload of process arrangement and fixture design in the manufacturing process.
20__ years have left in a hurry, and a hopeful new year is coming to us. The road is long in Xiu Yuan, and the way to find it is long in Xiu Yuan. The grand goal of the company for 20 years has been placed in front of us. I will be full of energy, forge ahead, make a good work plan, and make unremitting efforts for the development of the company and the realization of personal values.
