Busbar processing machine assembly and repair introduction

I. Considering the mechanical structure design of the assembly and maintenance of the busbar processing machine

1. Avoid removing other parts when removing a part

2. Avoid loading two mating surfaces at the same time

3. To leave the necessary operating space for the disassembled parts

4. Avoid working properly due to incorrect installation

5. Use special structure to avoid wrong installation

6. Simplify the assembly process with a symmetrical structure

7. Flexible sleeve should have a guiding part when installing

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

9. For easy installation with a robot, use a snap or internal locking structure

10. The fastener head should have a smooth straight edge for picking up

11. The part installation site should have the necessary chamfering

12. Parts feeding by automatic feeding mechanism should avoid entanglement and lap joint

13. Simplify the assembly movement

14. Reasonable division of parts for a machine

15. Minimize on-site assembly workload

16. Try to use standard parts

17. Parts should be easily removed after recycling.


Second, the threaded joint structure design

1. Do not install the counter when the height of the top nut is different.

2. The method of anti-loose should be reliable

3. The screw structure subjected to bending moment should minimize the force of the thread

4. Avoid the bending stress of the screw

5. Positioning with threaded parts

6. The screw should be placed at the location where the stiffness of the coupled part is the greatest.

7. Avoid excessive deformation of the joint when tightening the nut (or screw)

8. Flange bolts should not be placed directly below

9. The bolt spacing of the side cover should be considered for sealing performance.

10. Do not pierce the screw hole to prevent leakage

11. Threaded holes should not pass through two welded parts

12. For deep screw holes, the corresponding boss should be designed on the part.

13. Do not stick the head of the fastening bolt of the high-speed rotating body

14. Screw holes to avoid intersection

15. Avoid bolts passing through the chamber with temperature difference

16. It is not appropriate to arrange anchor bolts near the end of the foundation concrete.

17. Shear bolts should have a large contact length

18. Consider that there is enough wrench space when the nut is tightened.

19. The bolt diameter, spacing and joint thickness of the flange structure should be properly selected.

20. To ensure the installation and disassembly of the bolts

21. The set screw can only be added in the direction of not carrying the load.

22. Aluminum gaskets should not be used in electrical equipment

23. Screws with plating on the surface, the plating size should be left before plating.

24. The hole edge of the screw hole should be chamfered

25. When the screw tip thread is in danger of being bumped, there should be a cylindrical end to protect the thread.

26. When fixing with multiple countersunk screws, it is impossible for each countersunk to be tightly attached.


Third, the positioning pin, joint pin structure design

1. The distance between the two positioning pins should be as far as possible

2. Symmetrical parts, positioning pins should not be placed in a symmetrical position

3. Two positioning pins should not be placed on two parts

4. The pin holes of the matching parts should be processed at the same time

5. The pin hole of the quenched part should also be matched

6. The positioning pin should be perpendicular to the joint surface

7. Must ensure that the pin is easy to pull out

8. It is not suitable to install locating pins on the interference fit surface.

9. Appropriate measures should be taken for pin assembly that is difficult to observe.

10. Installing the positioning pin should not make the parts difficult to disassemble.

11. Avoid unbalanced forces when transmitting force with pins
