Press fitting tool

Abstract

The invention relates to a press fitting tool. The press fitting tool is used for press fitting a belt wheel on a motor rotating shaft, and comprises a supporting assembly and a jacking piece. The supporting assembly comprises a supporting platform, wherein the supporting platform is used for bearing a motor rear end cover, the supporting platform is provided with a positioning table protruding upwards, and the positioning table can be inserted into a shaft hole of the motor rear end cover so as to restrain a motor. The supporting assembly further comprises an elastic sliding mechanism, wherein the elastic sliding mechanism is used for restraining the supporting platform so that the supporting platform can only move in the vertical direction and provide upward restoring force for the supporting platform when the supporting platform bears downward acting force. In the process that the supporting platform vertically moves downwards, the upper end of the jacking piece can stretch out of the vertically-formed through hole of the positioning table and abut against the lower end of the motor rotating shaft. The belt wheel is pressed on the motor rotating shaft through the press fitting tool, and the undesirable phenomenon of swinging of the motor rotating shaft can be avoided.

Description

technical field [0001] The invention relates to a motor tooling, in particular to a press-fitting tool for pressing a pulley onto a motor shaft. Background technique [0002] Pressing the pulley onto the motor shaft is the post-process of the motor assembly line. This process has always been a bottleneck affecting the efficiency of the entire production line. There are two main problems: 1. When press-fitting the pulley, the lower end of the motor shaft needs to be supported as a force point, otherwise, the bearing will be damaged; 2. When press-fitting the pulley, since the force point of the motor shaft is small , the pressure is difficult to achieve vertical downward, and it is easy to cause the bad phenomenon of the motor shaft swing. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a press-fitting tool that overcomes the above problems or at least partially solves the above problems. [0004] The press-fi...
