Snap ring press-fitting device for engine piston pin

Abstract

The invention provides a snap ring press-fitting device for an engine piston pin applied to the technical field of auxiliary equipment of assembling an automotive engine piston pin. An annular snap ring slot (3) is formed in the edge position of a piston pin hole (2) of the snap ring press-fitting device for the engine piston pin; a piston supporting part (5), a main supporting column (6) and an auxiliary supporting column (7) are arranged on a device base (4) of the snap ring press-fitting device for the engine piston pin; the end part of one end of a press-fitting handle (8) is connected to the main supporting column (6) in a hinging manner, a snap ring pressure head (9) is movably mounted on the press-fitting handle (8), a press-fitting guiding part (10) is arranged on the auxiliary supporting column (7), and a guide hole (11) is formed on the press-fitting guiding part (10). The snap ring press-fitting device for the engine piston pin provided by the invention is simple in structure, can conveniently and rapidly press-fit a single piston pin snap ring at one time in position, and is accurate to press-fit, so that the snap ring press-fitting operating strength is reduced, and the snap ring press-fitting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of assembly auxiliary equipment for piston pin snap rings of automobile engines, and more specifically relates to a press-fitting device for piston pin snap rings of engines. Background technique [0002] At present, there are two ways to assemble the piston pin snap ring of the engine piston: manual press-fitting and equipment press-fitting. Safety accidents: Although equipment press-fitting has high efficiency and good safety, the cost of the equipment itself is high, the production and debugging cycle is very long, and the flexibility is poor, which is not conducive to the company's cost reduction and rapid response. At present, some enterprises have made their own manual press-fitting devices for piston pin snap rings. However, due to the particularity of the piston structure, the success rate of these press-fitting devices is generally not high, and the operation is difficult, the comfort is poor, and t...

[0002] At present, there are two ways to assemble the piston pin snap ring of the engine piston: manual press-fitting and equipment press-fitting. Safety accidents; although equipment press-fitting has high efficiency and good safety, the cost of the equipment itself is high, the production and debugging cycle is very long, and the flexibility is poor, which is not conducive to the company's cost reduction and rapid response

At present, some enterprises have made their own manual press-fitting devices for piston pin snap rings. However, due to the particularity of the piston structure, the success rate of these press-fitting devices is generally not high, and the operation is difficult, the comfort is poor, and the work is violent. There are potential hazards in both the workpiece and the workpiece, which cannot meet the actual work needs
