13、 Structural design of positioning pins and connecting pins

The distance between the two positioning pins should be as far as possible
For parts of symmetrical structure, positioning pins should not be arranged in symmetrical positions
3. Two positioning pins should not be arranged on two parts
Pin holes of matching parts shall be processed simultaneously
The pin holes of hardened parts should also be matched
6. The positioning pin should be perpendicular to the joint surface
7. It must be ensured that the pin is easily pulled out
8. Locating pins should not be installed on the interference fit surface
Appropriate measures shall be taken for pin assembly that is difficult to observe
10. Installation of positioning pins should not make it difficult to disassemble parts
11. Avoid generating unbalanced force when transmitting force with pins
