Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0037] Such as figure 1 , Image 6 As shown, the engine piston pin snap ring press-fitting tooling of the embodiment of the present invention includes a bracket 1 and a pressure rod 2 fixed on the bracket 1 and capable of being controlled to expand and contract; the bracket 1 includes a support seat 10 for supporting the engine piston. The rod assembly P1 has a positioning device on the support seat 10; the front part of the pressure rod 2 is the pressure head 20, and the middle part is provided with a boss, named as the upper boss 21, and the snap ring can be placed on the pressure head 20 of the pressure rod 2 And it is conflicted by the upper boss 21 table; the position of the pressure rod 2 corresponds to the position of the support seat 10. Preferably, the indenter 20 is made of 65Mn material, the hardness is HRC45-50 after heat treatmen...
