The invention relates to the technical field of engines, in particular to engine piston pin clamp spring press-fitting equipment. The equipment comprises a connecting rod piston positioning device which is provided with a piston hole, and clamp spring grooves are formed in the two ends in the piston hole; the two clamp spring press-fitting devices are arranged on the two sides of the connecting rod piston positioning device respectively, and each clamp spring press-fitting device comprises a clamp spring guide sleeve which is coaxial with the piston hole, and a clamp spring is assembled in the clamp spring guide sleeve; a push rod; the first driving mechanism is used for driving the clamp spring guide sleeve to be connected with the end face of the piston hole; and the second driving mechanism is used for driving the push rod to extend into the clamp spring guide sleeve and pushing the clamp spring to enter the piston hole, so that the clamp spring is assembled in the corresponding clamp spring groove. According to the engine piston pin snap spring press-fitting equipment, the first driving mechanism and the second driving mechanism are arranged to serve as power output components, the push rod and the snap spring guide sleeve are arranged to accurately mount the snap spring, and compared with the prior art, the working efficiency and the press-fitting quality of snap spring press-fitting are greatly improved.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to a press-fitting device for an engine piston pin circlip. Background technique [0002] The engine is the heart of the car and its quality is very important to the performance of the car. The connecting rod and the piston of the automobile engine are connected in series through the piston pin. The two ends of the piston pin are equipped with circlips. The tension of the circlips is used to position the piston pin axially to avoid the axial movement of the piston pin in the pin hole. Scratched the cylinder. At present, there are many ways to assemble the circlip of the engine piston, but all of them use the spring structure to manually press the circlip. Due to the particularity of the piston structure, the qualification rate of these press-fitting devices is not high, the operation is difficult, and the efficiency is low. , unable to meet the actual work needs.
