The next workshop is actually a necessary stage that robots can't circumvent, just as socialism is the primary stage of communism (although this seldom has been mentioned so far, politics must be passed back), this is a process.
As a mechanical major student, we often hear teachers (they may not have done it themselves) and the seniors said: You must go to the workshop more, without going through the workshop, you can't mature and progress.
It seems that a design engineer who has not been in the workshop is like a newcomer who has not married in love. There is no reliable foundation at all. Today, as a person coming over, I want to talk about why we are going to the workshop, what are we going to do?
What does the workshop look like?
In the eyes of most people, the workshop is the roar of the machine, the floor and the wall are full of oil, the old equipment and the numb workers are working in the same way. In your impression, it seems that you can no longer find a worse working environment than here. It is hard to accept, but it is better to work in this environment for a few years. Imagine the propaganda videos of Internet companies, the tall office, the most shameful is the gym and coffee shop. The computer is the latest configuration, the seat has a rotating folding function, and the office desk always has its favorite Flowers and beloved toys.
The workshop has become a nightmare for contemporary college students to a large extent. It is a place of conflict from the heart. Even many people who are willing to engage in or are engaged in the machinery industry are deeply hated and afraid of the next workshop.
In fact, we still have to have a deeper understanding and understanding of this industry. Modern manufacturing companies, although compared with many Internet companies, there is a certain gap between their working environment and industry treatment, but with the advancement of technology and industry 4.0 With the rapid spread of popularity, many companies have made unprecedented progress in automation and intelligence.
Modern factory buildings, clean and bright constant temperature workshops, busy and unskilled robots have replaced a lot of manual manual operations. Workers have been greatly improved both in labor intensity and in labor environment. They are more like It is a driver who operates intelligent devices, and it is easy and professional to get everything that seems complicated.
And this is definitely a big trend in the future. It is the inevitable development of manufacturing enterprises. Many of the factories that college students have visited during their internships and internships are mostly obsolete and run-down companies.
That's because your school can only be connected to such a company because of its resources, or only those companies that don't have much technical content will open up to you moderately, and many high-level automation companies are kept secret because of technology. The relationship is not open to outsiders, even those who are in the unit, those who do not have the authority and work needs are not allowed to enter.
This is a similar regulation in many industrial 4.0 companies, because the layout of the production and the process of the process, for many professionals, you can learn at a glance, but take the lead in doing these technologies and processes. Enterprises and teams have spent a lot of manpower and material resources to tackle problems, and it is easy to be stolen by others. This is obviously not economical and is not allowed.
The first is the workshop of machining. What is the mechanical processing that you need to learn?
1. Familiar with the processing capability and processing range of various processing equipment
The equipment we usually see in ordinary workshops such as lathes, milling machines, planers, grinding machines, boring machines, drilling machines, laser cutting, wire cutting, etc., what are their processes, and how much processing accuracy can they achieve?
What is the state of the art at the forefront of these devices (it can be easily learned from the Internet), what state and level your factory is in, what kind of state and level the industry is in your city. These are very useful for your future product design.
2, familiar with the processing technology of the product
For example, how the machining process is arranged, what kind of tools and fixtures are required for each process, and how the machining parameters of the equipment are adjusted.
Whether the processing accuracy is consistent with the specifications of the drawings, how to check whether the processed workpieces are qualified, what kind of inspection tools are used for inspection, etc. These problems are accumulated by thinking, which is the basis and common sense for your future design.
3. Learn how to operate processing equipment
Although you don't need to be proficient, you must know how this thing works and think about how the structure of these devices is handled.
If you are designing these devices, how would you deal with them, whether there are better structures and processing methods than before, discovering the deficiencies and advantages of the devices during the use of the devices, and then absorbing and transforming them into their own capabilities.
4, learn to misplace
A person will make all kinds of mistakes in his career, and reflection on these mistakes is the cornerstone of progress, but it is costly to make mistakes. Who will pay for these costs for you, the workshop is the unlucky one, why? Make mistakes from the workshop, because the cost of making mistakes from the workshop is the lowest.
If you make mistakes from R&D, you will find that the cost is too high, because many development errors can only be discovered when the equipment is assembled and debugged. At this time, most of the costs have already been invested, the workshop is different, and you are at most It is a mistake in the process, and in many cases, this kind of mistake is saved. Even if it is not saved, the cost is not too high, it is acceptable.
5. Learn to communicate with others
Most workers' masters have natural kind and rational communication. They may be rude and perhaps straightforward, but as long as you treat each other sincerely, you can quickly integrate into a new social environment.
However, the innocence and sharpness that comes from the student era will be somewhat ruthless by the reality, and many skilled workers will deliberately make a certain degree of difficulty for the newly graduated college students in some technical difficulties.
This may be a common problem for people who are doing technology. They always want to find an opportunity to show their abilities. It is also an opportunity to express themselves. Moreover, it is a very happy thing to be able to stump a so-called "Pride of Heaven". At least for them.
6. Cultivate your professional attitude
Work in the workshop, no matter how small, for the newly-introduced college students, it is inevitable that the tea will be poured from the end of the tea, and it is inevitable to wipe the table. In fact, this is also a way to test personal attitudes. Only when it is competent for small things, can it be done. The opportunity to take big events, so every small task is your step to a higher destination. Before you have the ability and opportunity to do big things, then learn how to accomplish those little things.
If you are in a mechanical assembly workshop, what should you learn?
1. Assembly process of the product
A careful analysis of how a product operates from scattered parts to molded equipment, including those assembly processes, those operating procedures, and what assembly tools are needed.
What kind of inspection tools are needed, what kind of assembly tooling is needed, what assembly skills are needed, what inspection rules and procedures are required, etc., which will greatly benefit your future design.
2, the use and operation of various assembly tools
For example, the use of hand drills, the use of shovel blades, the use of dial gauges, the use of flat feet and square feet, the use of level meters, the use of laser interferometers, etc.
The use of these tools allows you to build a rational understanding of a product. In your future product design career, no matter what part design, you can habitually form your own style, and fully understand the assembly. Process without the flaws of assembly interference or errors.
3. Learn to operate various CNC systems
As a design engineer, although the hard use of the operating system of the device is hard, if you are proficient in using various operating systems, it is definitely a very good skill for you, because during the debugging and inspection process, The operation of the operating system is inevitable.
We currently use more operating systems: FANUC system, Siemens system, Mitsubishi system, Huazhong CNC, Guangzhou CNC, Kanedi CNC, etc. In fact, the operating methods of these operating systems are similar, will also You can quickly learn another one, one pass.
4. Have a deeper understanding and understanding of the functions and assembly processes of various functional components and parts in the assembly process.
In the future design, some wrong structural handling and selection misunderstandings are avoided. The mechanical design engineers who have not experienced the assembly site are indeed unqualified design engineers.
This has a very similar place with Zhao Kuo's paper. There are many things. The gap between the assembly site and the theory is very large. Or, in reality, your design is impossible to achieve, or the assembly is difficult. Big, or it is impossible to assemble at all.
5, learn the ingredients of the "match" in the assembly process
The assembly process is not a purely "installed" process, but also involves a "matching" process, such as the accuracy and contact of the guide rails, the installation and positioning of the screw, etc., all of which require on-site precision. Technology and process, if you have no personal experience, you can not complete and learn, the structure of your design process will also be related to the hidden dangers.
In fact, the workshop is a basic accumulation. The high-rise buildings are on the ground, and the cattle are forced to rely on the foundation. The next workshop is a process of laying the foundation. It is a rooted process, a process of accumulation. Only the foundation is laid. The roots are deep, and the accumulation is enough, you can complete more and more powerful designs.
