TECHNICAL FIELD

[0001] The present application relates to the technical field of plate spring assembly, in particular to a plate spring pin assembling device. BACKGROUND

[0002] The plate spring is very common in commercial vehicles. The fixed installation of the plate spring is completed by inserting the plate spring pin into the pin shaft hole of the plate spring support. In the assembly operation of the automobile factory, the method currently adopted is that one worker holds the plate spring pin with his hand, and the other worker hits the plate spring pin with a hammer to make the plate spring pin hit into the pin shaft hole of the plate spring support. Using this method, firstly, the worker holding the plate spring pin has the safety hazard of being hit, and secondly, since the worker cannot guarantee the right holding of the plate spring pin and the hammering force is relatively large, the plate spring support will be impacted by the plate spring pin, which will damage the structure of the plate spring support and bring safety hazards to the whole vehicle. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a plate spring pin assembling device which can accurately assemble the plate spring pin into the pin shaft hole of the plate spring support without damaging the plate spring support.

[0004] In order to solve the above technical problem, the technical scheme adopted by the present application is as follows: a plate spring pin assembling device, comprising a plate spring support and an assembling device, the plate spring support has opposite and spaced apart front and rear end faces, the front and rear end faces are provided with pin shaft holes, and the two pin shaft holes are coaxial;

[0005] The assembling device comprises a positioning part and a movable part which are opposite and spaced apart, the positioning part has a sliding block which is matched with the pin shaft hole of the rear end face, and the sliding direction of the sliding block is parallel to the axis of the pin shaft hole;

[0006] The movable part comprises a linear reciprocating device and a push block connected to the movable end of the linear reciprocating device, and the push block is coaxial with the sliding block, and the moving direction of the push block is towards the pin shaft hole of the front end face.

[0007] The beneficial effects of the present application are as follows: when assembling the plate spring pin, the sliding block on the positioning part of the assembling device is inserted into the pin shaft hole on the rear end face of the plate spring support, so that the push block, the pin shaft hole and the sliding block are located on the same axis, then the assembler can place the plate spring pin between the front end face of the plate spring support and the push block, and then the push block can be driven by the linear reciprocating device to move towards the pin shaft hole of the front end face, so as to assemble the plate spring pin into the two pin shaft holes of the front and rear end faces of the plate spring support; at the same time, when the plate spring pin is assembled into the pin shaft hole on the rear end face of the plate spring support, the sliding block will gradually exit the pin shaft hole on the rear end face under the pushing of the plate spring pin, so that after the plate spring pin is completely assembled into the plate spring support, the assembling device will automatically separate from the plate spring support, so as to facilitate the assembler to remove the assembling device.
