Description

Technical Field

[0001] The utility model relates to the technical field of teaching equipment, and specifically to a modular multifunctional four-axis teaching and research processing center. Background Art

[0002] At present, universities and vocational colleges have set up mechatronics majors. The theoretical courses include mechanical processing and electrical automation control. There are also practical courses such as "Metalworking Practice" and "Engineering Training". The teaching methods of these courses are often relatively simple. Machine tool processing accounts for a large proportion of such courses, but from the perspective of cost investment, teaching effect and operational safety, colleges and universities are generally not equipped with large machine tool equipment. If the machining technology is not introduced or only used as a theoretical explanation without relevant practice, it is contrary to the purpose and requirements of teaching. This has created a very embarrassing situation. On the one hand, it is due to the need for teaching, and on the other hand, it is due to economic considerations. If relevant equipment is introduced, the input and output are not proportional, and it is very likely that the income will not cover the expenditure. At present, many colleges and universities do not have relevant equipment, which will cause shortcomings in students' abilities.

[0003] In the traditional teaching process, teachers can only explain the principles of machining equipment to students in an abstract way or by playing similar videos, which makes it difficult for students to understand. Through investigation, it is found that when students only learn theoretical knowledge, it is boring and cannot be combined with practice immediately. The teacher's explanation is also not intuitive, which is time-consuming and laborious.

[0004] Some colleges and universities will purchase old machine tools that have been eliminated by enterprises and build machining plants or internship plants. However, many of the equipment in these machining plants are still manually operated and controlled rather than CNC machine tools. They cannot keep up with the times and are easily out of touch with existing intelligent control machine tools. In addition, due to the need to process high-hardness steel parts, the circulation and cooling system of old machine tools is too complicated, resulting in a large footprint and difficulty in moving the machine tools. Some colleges and universities have their own cooperative enterprises as their internship bases, but due to production needs, the enterprises cannot guarantee the timeliness of equipment use, and the enterprise equipment cannot be disassembled, so students lack specific knowledge of the internal structure. Some colleges and universities also use demonstration models to assist teaching in the process of machine tool teaching, which has achieved certain results. However, the existing machine tool teaching models on the market have low simulation and cannot run automatically. They are far from real machine tools and cannot reflect the development direction of modern manufacturing technology. Utility Model Content
