Abstract

The invention relates to a bushing pressing device. The bushing pressing device comprises a base and a die, wherein a U-shaped support pedestal is installed in the middle of the base, a vertical frame is installed on the left side of the support pedestal, a rotary shaft is installed in the middle of the support pedestal, the bottom end of the rotary shaft is connected with the support pedestal through a bearing, a support plate is fixedly connected to the upper end of the rotary shaft, a turbine and a worm which is matched with the turbine are arranged in the middle of the rotary shaft, two through holes are formed in both ends of the support plate, a groove which is matched with the bottom end of a workpiece is formed in the middle of the support plate, a limiting block is installed on one side of the groove, an air cylinder is installed at the upper end of the vertical frame, a stepped stamping shaft is fixedly connected to the front end of an air cylinder piston rod on the air cylinder, the stamping shaft is divided into a connecting part, a thrust part and an operating part from top to bottom in sequence, the die is arranged below the stamping shaft, and a machining hole which is matched with the workpiece is formed in the middle of the die. The bushing pressing device has the advantages of simple structure, reasonable design and simplicity in operation, and the accuracy fully meets the requirement.

Description

technical field [0001] The invention belongs to the field of machining of mechanical parts, in particular to a pressing bushing device. Background technique [0002] In mechanical movement, when the gap between the shaft and the hole is worn to a certain extent due to long-term friction, the parts must be replaced, so the material with lower hardness and better wear resistance is selected as the shaft sleeve or bushing. , which can reduce the wear of the shaft and seat. Replace the shaft sleeve or bushing when it is worn to a certain extent, which can save the cost of replacing the shaft or seat. Therefore, the cooperation of bushings and bushings is widely used in the connection of shafts and holes. [0003] In the existing installation process, it often occurs that the surface of the bush and the shaft sleeve is damaged and does not meet the process requirements, resulting in assembly waste parts. Contents of the invention [0004] In order to solve the technical prob...
