Mechanical structure design: those issues that must be considered about the convenience of equipment assembly and maintenance

In order to ensure the quality of the assembly and the convenience of subsequent maintenance, when designing the assembly, the rationality of the assembly structure and the convenience of structural disassembly must be considered when designing the assembly to ensure the performance of the machine and components, and to ensure the performance of the parts. It is convenient to process and disassemble. The following are the issues that must be considered regarding the convenience of equipment assembly and maintenance:

1. Avoid having to remove other parts when disassembling one part

2. Avoid loading two mating surfaces at the same time

3. It is necessary to leave necessary operating space for the disassembly and assembly of parts

4. Avoid malfunction due to wrong installation

5. Adopt special structure to avoid wrong installation

6. Use symmetrical structure to simplify assembly process

7. There must be a guiding part when installing the flexible sleeve

8. Matching parts that are difficult to see must have a guiding part

9. In order to facilitate the installation with a manipulator, a buckle or internal locking structure is adopted

10. The head of the fastener should have a smooth straight edge for easy picking

11. The installation part of the part should have the necessary chamfer

12. The parts supplied by the automatic feeding mechanism should avoid entanglement and overlap

13. Simplify the way of assembly movement

14. A machine should be divided into components reasonably

15. Minimize the workload of on-site assembly

16. Try to use standard parts

17. After parts are damaged, they should be easy to remove and recycle materials
