Time flies, I'm a junior. However, most people don't know enough about this major. In order to make us know more about electromechanical products and equipment, improve our understanding of electromechanical engineering manufacturing technology, deepen our perceptual knowledge of electromechanical application in various industrial fields, broaden our horizons, understand relevant equipment and technical data, and be familiar with the processing technology of typical parts, the school specially let us visit a factory with many types of electromechanical integration equipment and advanced production technology. Zhang Qing and I went to Xingguang Machinery Processing Factory in Tianwang Town, chencang district City, Baoji City for half a month's production practice. Understand the production situation of the factory, all kinds of knowledge related to this major, the work situation of workers in various factories and so on. I personally experienced the application of knowledge and practice, the application of electronic technology in machinery manufacturing, the application of precision machinery manufacturing in machinery manufacturing and so on.
The development trend of machinery manufacturing industry can be summarized as "four modernizations": flexibility, agility, intelligence and informatization.

A few days before the internship, the teacher of the factory internship department introduced me to the factory, which gave me a general understanding of the factory and made us cherish this internship opportunity more. Then, safety education will be conducted by the factory safety officer. Everything is covered with blood, which makes me feel the value of life and the importance of safety. In the following time, I visited some large workshops of the company, such as engine factory, tool factory, chassis factory, gearbox factory, foundry factory, forging factory and body factory, and saw advanced production methods and management methods. This internship is a practical education link. On the one hand, it consolidates the theoretical knowledge in the original work and lays the foundation for the professional knowledge to be studied in the future; on the other hand, it wants to master the essentials and draw inferences from others.
Next, I went to the precision machine tool workshop. As the name implies, precision machine tool factory is a large workshop that produces some machine tools with high machining accuracy and high technical requirements. Mainly processing some high-precision small parts or some high-precision machine tools, such as M-class and mm-class surface grinders. Because the processing requirements are higher and the machines are more precise, some of them have to be served at constant temperature. Only in this way can the working performance of the machine tool be guaranteed, and then the machining accuracy requirements of the machined parts can be guaranteed.
After listening to the explanation of the worker's master, I understand that the processing flow of general parts is as follows:
Blank-scribing-planer (technically leaving machining allowance)-rough turning-heat treatment, dressing-semi-finishing of lathe-grinding-gear machining-quenching (tooth surface)-grinding surface.
Processing technology of gear parts;
Rough turning-heat treatment-finish turning-grinding inner hole-grinding core, shaft end face-grinding the other end face-hobbing-clamping teeth-shaving-countersunk keyway-fitter-completion.
The finishing workshop has three machining centers and several CNC machine tools. Numerical control machine tools are small in size, relatively cheap and convenient to process. The machining center has a tool holder and multiple tables, which can process multiple working faces at the same time, which not only avoids the error caused by misalignment of benchmarks, but also greatly improves the machining efficiency. However, the machining center is bulky, expensive, and requires higher environment, which increases the product cost.
During my internship in Seiki Workshop, I greatly enriched my knowledge about parts processing technology and expanded my knowledge. In this internship, I learned most about the importance of CNC machine tools in mechanical manufacturing. It is a combination of electronic information technology and traditional processing technology. It integrates modern precision machinery, computer, communication, hydraulic pneumatic, photoelectric and other multidisciplinary technologies, and has the characteristics of high efficiency, high precision, high automation and high flexibility. It is an indispensable production equipment for cutting-edge industries. At present, most of China's CNC machine tools come from advanced foreign manufacturers, and China's manufacturing industry lags far behind developed countries in terms of quantity, accuracy and performance indicators, which requires us to catch up.
During my internship, I made my own handicrafts by studying lathe work. Everyone who practises in milling, turning and planing can make 1 workpiece according to the drawing requirements. Turner and fitter are the hardest workers, and Turner is the most dangerous. In the next 1 day, I must master the essentials of turning lathe first, and then screw out the hammer handle according to the drawing requirements. Although I was sore all over after the afternoon of 1, I couldn't help but feel a sense of accomplishment when I saw the finished product made in the factory for the first time in my life. The experience I got from this internship is:
1. Through this internship, I learned about the production mode and process of modern machinery manufacturing. Familiar with the main molding methods and processing methods of engineering materials, the working principle and typical structure of the main equipment used, the use of fixtures and measuring tools and the safe operation technology. Understand the knowledge of mechanical manufacturing technology and the application of new technology, new technology and new equipment in remanufacturing.
Second, I have preliminary independent operation skills in the main molding and processing methods of recycled materials.
Thirdly, by understanding, being familiar with and mastering certain engineering basic knowledge and operation skills, we have cultivated, increased and strengthened our engineering practice ability, innovation consciousness and innovation ability.
Fourthly, we have cultivated and exercised our views on labor, quality and economy, enhanced our awareness of observing labor discipline, safety technical regulations and caring for state property, and improved our overall comprehensive quality.
During the whole internship, my discipline was very strict, and I made the internship safety rules. At the same time, I strengthened the practice diary, cleaned the machine tool site, and complied with the requirements of various types of work safety operation procedures, which played a very good role in promoting the cultivation of my comprehensive engineering quality.
Summary: The internship that lasted nearly half a month is over. This internship really touched the front line of machinery manufacturing industry, and learned about the development status and development trend of machinery manufacturing in China. In the new century, science and technology will develop at a faster speed and be more closely integrated into various fields, which will greatly broaden the development direction of machinery manufacturing.
Its development trend can be summarized as "four modernizations": flexibility, agility, intelligence and informationization. Even if the process equipment and process route can meet the needs of producing various products, meet the needs of rapidly changing processes and products, make them flexibly coordinate with the environment, shorten the time to market, and make the production of enterprises flexible and agile, there are still greatly reduced consumption of materials and people in the manufacturing process, highly automated production, intelligent pursuit of human intelligence by machines, and informationization that mainly relies on the power of matter and energy to make information generate value.
Of course, the four development trends of machinery manufacturing industry are not separated, they are organically combined, interdependent and mutually promoting. At the same time, due to the continuous progress of science and technology, there will be new development directions. What we saw before was the development of machinery manufacturing industry on its own line. But as a part of social development, it will also be more widely integrated with other industries. The importance of machinery manufacturing industry in the 2 1 century is manifested in its globalization, networking, virtualization, intelligence and green manufacturing coordinated with environmental protection. It not only liberates human beings from heavy physical labor, but also liberates human beings from tedious mental work such as calculation and analysis, so that they have more energy to engage in high-level creative labor, intelligently improve flexibility, and make the production system have more perfect judgment and adaptability. Of course, all this needs further efforts from all of us.
