Getting out of the workshop is actually a necessary step that a robot cannot avoid, just as socialism is the primary step of communism (although this statement is rarely mentioned now, you must have the policy memorized. It is a process).
As a mechanical engineering student, we often hear teachers (who may have never done it themselves) and seniors say: we need to go to the workshop more, without experiencing workshop training, we cannot mature and progress.
It seems that a design engineer who has never been to a workshop is like a newlywed who got married without falling in love. There is no reliable basis. So today, as someone who has been there, I want to talk about why we go down to the workshop and what we do there?
What does the workshop look like?
To most people, the workshop is just the roar of machinery, with oil stains all over the floor and walls. Old equipment and numb workers mechanically perform the same processing work. The only thing that can get some life back is work. slight mark on the wall. Some encouraging slogans, not painful but full of dust, as if it has never been cleaned, and it seems that there is no need to clean it, because there are dirtier places everywhere, but it looks so clean. get up.
In your mind, it seems like you can’t find a worse work environment than here. It’s hard to accept even watching it, let alone working in this environment for a few years. If you are unlucky, you may have to work. for a lifetime. What kind of self-punishment is this? A thought of life doubt comes to mind: God, what have I done wrong?
Imagine these promotional videos of Internet companies, high offices, and the most shameful thing is that they also have gyms and cafes. The computers are all equipped with the latest configurations, the seats have rotating and folding functions, and your favorite books are always placed. on the desktop. Flowers and favorite toys. What’s even more outrageous is that some companies allow you to bring pets to work, it’s clearly on vacation. Some bosses are so evil that they can let you work anywhere. time. You are here to do charity Yes.
To a large extent, the workshop has become a nightmare for contemporary students. It is a place of inner resistance. Even many people who want to get involved or are currently involved in the machinery industry hate the shop and avoid it.
In fact, we still need to have a deeper understanding of this industry. Although modern manufacturing enterprises have certain shortcomings in their working environment and industrial processing compared with many Internet enterprises, with the progress of technology and industry 4.0, with the accelerated popularization, many enterprises have achieved unprecedented progress in automation and intelligence.
Modern factories, clean, bright workshops with constant temperatures, and busy but industrious robots have largely replaced manual operations. Workers have improved significantly in terms of work intensity and working environment. They are more like a driver using smart equipment and handles. anything that seems complicated easily and professionally.
And it is definitely a major trend in the future, and it is inevitable for the development of manufacturing enterprises. The factories that many students visit during their internships and internships are mostly old and dilapidated companies.
This is because your school can only contact such companies due to resource constraints, or in other words, only those companies without much technical content will be moderately open to you, while many high-end automation companies range are confidential due to their technology. open to foreigners, even employees of its unit, and people without authorization and without the need for work are not allowed to enter.
Many Industry 4.0 companies have similar regulations. Due to the organization of production and the flow of processes, many professionals can learn everything at a glance, but those who are the first to tackle these technical and process issues are the companies and teams that spend a lot of money. human and material resources to resolve key issues, and others can easily learn from them. This is obviously not cost-effective and is not permitted.
For example, in Japanese companies, while discussing with a Japanese sales engineer about threaded rods and linear rails, I asked what level of automation Japanese companies in the same industry had achieved. clients They are simply not given the full picture of the project.
He only talks about the area he is responsible for. Entry into their business also requires specific authorization. Photography and videography are not permitted. (Japanese people speak Mandarin very well. Chinese is a very difficult language to master. , they said I can’t really tell it’s Japanese, so we Chinese still have to work hard, success doesn’t doesn’t come overnight).
This has gone too far. Everything went to Japan. Let’s return to our initial subject: why do you want to leave the workshop and what are you going to do? This is confusing to many people. in two aspects. This is also my personal question.
what do you need to learn
The first is a mechanical processing workshop. What do you need to learn about mechanical processing?
1. Familiar with the processing capabilities and processing scope of various processing equipment
We usually see equipment in ordinary workshops such as lathes, milling machines, planers, grinders, boring machines, drilling machines, laser cutting machines, wire cutting machines, etc. What processes are they used for processing and what is their processing accuracy?
What is the state of the advanced technology of these devices (you can easily learn it on the Internet), what state and level is your factory, what is the state and level of your city, and this industry, It is ? very useful for the design of your future product.
2. Familiar with product processing technology
For example, how processing procedures are organized, what types of tools and accessories are needed for each process, and how equipment processing parameters are adjusted.
Whether the processing accuracy is consistent with the drawings, how to check whether the processed part is qualified, what kind of inspection tools to use for inspection, etc. These questions need to be thought through and accumulated. This is also basic and common sense. for your future design.
3. Learn to use processing equipment
Although you don’t need to be very knowledgeable, you need to know how this thing works and think about how the structure of these devices is handled.
If you were to design these devices, how would you manage them? Is there a better structure and method of treatment than today? When using the equipment, you will discover the flaws and advantages of the equipment, and then absorb and transform them? in your own abilities.
What you need to know in the assembly workshop
If you are in a mechanical assembly shop, what do you need to learn?
1. Product assembly process
Carefully analyze how a product works, from scattered parts to molding equipment, what are the assembly processes, what are the operational procedures and what types of assembly tools are needed.
What kinds of inspection tools are needed, what kinds of assembly tooling are needed, what kinds of assembly skills are needed, what kinds of inspection rules and processes are needed, etc. This will be of great benefit to your future design.
2. Use and operation of various assembly tools
For example, the use of electric hand drills, the use of scrapers, the use of dial indicators, the use of square rulers and set squares, the use of levels, the use of laser interferometers , etc.
Using these tools allows you to establish a sufficient rational understanding of a product. In your future product design career, regardless of the type of part design, you can usually create your own style and fully understand the assembly process. the embarrassment of interference or assembly errors.
3. Learn to use various CNC systems
As a design engineer, although there are strict regulations on the use of device operating system, if you know how to use different operating systems skillfully, it will undoubtedly be a very good skill for you, because during the debugging and inspection process, Operations on the operating system are inevitable.
The operating systems we currently use frequently include: FANUC system, Siemens system, Mitsubishi system, Huazhong CNC, Guangzhou CNC, Kaindi CNC, etc. In fact, the working methods of these operating systems are similar. You can quickly learn and know another one. all about it.
4. Have a deeper understanding of the role of each functional component and parts in the assembly process and assembly process
And avoid structural processing errors and selection misunderstandings in future designs. Mechanical design engineers who do not have assembly site experience are in effect unskilled design engineers.
This is very similar to Zhao Kuo’s paper speech. For many things, the gap between the assembly site and the theory is very large. In other words, in reality, your design is simply impossible to achieve, or assembly is too difficult. Too big, or simply impossible to assemble, etc.
5. Learn the ingredients of “matching” in the assembly process
The assembly process is not a pure “installation” process, but also involves a “matching” process. For example, the precision and contact of guide rails, installation and positioning of screw rods, etc. all require on-site matching. accuracy, and among them If you do not have personal experience with the technology and processes, you will not be able to complete and learn them. Your structural treatment in the design process will also have corresponding hidden dangers.
In fact, being in the workshop is the accumulation of a foundation. A great building rises from the ground, and everything great depends on the foundation. Coming out of the workshop is a process of laying foundations, a process of putting down roots. a process of accumulation. Only by laying this foundation well, only when you have deep roots and sufficient accumulation, can you achieve more and better products.
