If you don't understand the busbar processing machine, don't say that you are doing machinery!

First, the structural design of the busbar processing machine to improve the accuracy

1. Try not to adopt a structural scheme that does not conform to the Abbe principle.

2. Avoid overlapping the errors caused by the amount of wear

3. Avoid processing error and wear amount superimposed on each other

4. The driving force action point of the guide rail should be applied to the pressure center of the frictional force of the two guide rails, so that the moments generated by the frictional forces of the two guide rails are balanced with each other.

5. For guide rails with high precision, it is not advisable to use a small amount of ball support.

6. In the deceleration drive chain that requires motion accuracy, the final stage gear ratio should take the maximum value.

7. The number of nut buckles for measuring spirals should not be too small.

8. The axial movement of the helical bearing must be strictly limited

9. Avoid unreasonable matching of bearing accuracy

10. Avoid unreasonable configuration of radial runout of bearings

11. Avoid tightening screws affecting the accuracy of the rolling guide

12. When the gap between the push rod and the guide is too large, a sinusoidal mechanism should be used, and the tangential mechanism should not be used.

13. The accuracy of the sinusoidal mechanism is higher than the tangential mechanism



Second, consider the structural design of ergonomics

1. Reasonably selected operating posture

2. The ratio of the height of the table to the size of the human body should be a reasonable value.

3. Reasonable resettlement adjustment to enhance the applicability of equipment

4. The mechanical control, control and display devices should be arranged in the most reasonable position in front of the operator.

5. The display device is in a reasonable form

6. The lettering on the dashboard should be clear and easy to read.

7. The size and shape of the knob should be reasonable.

8. The button should be easy to operate

9. The force required to operate the handle and the range of motion of the hand should not be too large.

10. The shape of the handle is easy to operate and exert force

11. Reasonably design the size and shape of the seat

12. Reasonable design of the material and elasticity of the seat

13. Do not have excessive noise in the working environment

14. The illumination of the operation site should not be too low

Third, the structural design of problems such as heat, corrosion and noise

1. Avoid using low-efficiency mechanical structures

2. The size of the oil tank should be large enough

3. The return fluid of the split system is cooled

4. Avoid high pressure containers, pipes, etc. exposed in the hot sun

5. Parts exposed to high temperatures are not allowed to be rubber, polyethylene plastic, etc.

6. It is not advisable to arrange the fuel tank inside the box parts of precision machinery to avoid thermal deformation.

7. For long mechanical parts, it is necessary to be able to freely deform when dimensional changes occur due to temperature changes.

8. Hardened material working temperature can not be too high

9. Avoid moisture condensation caused by high pressure valve deflation

10. The large thermal expansion box can be supported in the center.

11. The flanges connected by bolts are used as the joints of the pipes. When one side is exposed to sunlight, the two sides are different in temperature and elongation, resulting in bending.

12. Structures in contact with corrosive media should avoid slits

13. The liquid in the container should be cleaned out.

14. Take care to avoid mechanochemical wear (friction wear) on the contact surface between the shaft and the hub.

15. Avoid corrosion-resistant screw structures

16. When the steel pipe is connected with the copper pipe, it is easy to produce electrochemical corrosion, and a section of the pipe can be periodically replaced.

17. Avoid using structures that are susceptible to corrosion

18. Take care to avoid the impact fretting wear of the heat exchanger tubes

19. Reduce or avoid impact and collision of moving parts to reduce noise

20. High speed rotor must be balanced

21. The quality of the impacted parts should not be too small

22. In order to absorb vibration, the part should have strong damping.
