Positioning and pressing device for gear shaft hole lining thin-walled sleeve

Abstract

The invention discloses a positioning and press-mounting device for a gear shaft hole liner thin-wall sleeve, which comprises a die plate, a pressure lever, a pressure plate, a bolt, a die holder and a positioning seat, wherein coaxial through holes are respectively formed in the centers of the plate face of the die plate and the plate face of the die holder, a sliding sleeve extending out downwards is arranged in the through hole of the die plate, a guide rod extending out upwards is inserted in the through hole of the die holder, and a spring is sheathed on the guide rod and is in clearance fit with the sliding sleeve matched with the die plate, so as to form an elastic lifting die carrier acted by the die plate. The pressure lever is inserted in the positioning hole in the center from the bottom surface of the die plate, and is locked by the pressure plate and the bolt, and the small diameter section facing downwards is in clearance fit with the to-be-pressed copper sleeve inner hole. The positioning seat is mounted in the positioning hole in the center of the die holder, and a spigot matched with a workpiece is arranged toward the upper end surface. As the thin-wall copper sleeve liner is sheathed on the pressure lever, the rigidity is remarkably enhanced, and the efficient press mounting is facilitated.

Description

technical field [0001] The invention relates to a mechanical tool, in particular to a positioning and pressing device for a thin-walled sleeve lining a gear shaft hole. Background technique [0002] The reverse gear of a car is a moving part that transmits torque, and the inner shaft hole is provided with a thin-walled copper bush. Due to the small volume of the reverse gear of the car, the built-in bushing wall is very thin, the rigidity is poor, and the press-fitting quality is not easy to guarantee. In this industry, the ideal press-fitting quality is usually achieved by skilled workers manually. However, manual press-fitting has poor efficiency, high labor intensity, and unstable press-fitting quality, which cannot meet the requirements of mass production. Contents of the invention [0003] The invention mainly aims at the deficiencies of the prior art, and proposes a gear shaft hole liner thin-wall sleeve positioning and pressing device, which is reasonable in struct...
