Assembling tool for flat key on motor output shaft

Abstract

The invention aims to provide an assembling tool for a flat key on a motor output shaft. The assembling tool is convenient to assemble without flat key damage and is more accurate in assembling the flat key without damage to the bearing for locating and fixing the output shaft. In order to achieve the above objectives, the following technical scheme is used: the assembling tool for the flat key onthe motor output shaft. The assembling tool comprises a base plate and a locating block fixed on the base plate. The locating block is provided with an output shaft avoidance groove which is throughin a front-and-back direction and used for avoiding the output shaft and a flat key avoidance groove which is used for avoiding the flat key on the shaft. The flat key avoidance groove is communicatedwith the output shaft avoidance groove, and the flat key avoidance groove is located on the upper side of the output shaft avoidance groove. A first linear driving mechanism is arranged at the rear side of the locating block. A locating pin is fixed at the output end of the first linear driving mechanism. A pressing groove for passage of a pressing block is formed in the locating block. The pressing groove is located on the upper side of the flat key avoidance groove and is communicated with the flat key avoidance groove. The pressing groove penetrates upward through the upper end surface ofthe locating block.

Description

technical field [0001] The invention relates to a flat key assembly tool on a motor output shaft. Background technique [0002] When assembling the flat key on the output shaft, it is necessary to fix the output shaft to avoid the rotation of the output shaft, so as to ensure the position of the key groove so that the flat key can be smoothly assembled in the key groove. In the prior art, the flat key is knocked into the keyway of the output shaft with a small hammer, no matter by radial knocking (knocking the plane of the flat key along the radial direction of the output shaft) or axial knocking (knocking the flat key along the axial direction of the output shaft). knocking at both ends) will damage the flat keys. [0003] When performing axial knocking, set the output shaft vertically, and knock the flat key into the keyway vertically. Since the two axial ends of the flat key are arc-shaped, the force exerted by the pressure head on the end of the flat key will cause dama...

Problems solved by technology

[0003] When performing axial knocking, set the output shaft vertically, and knock the flat key into the keyway vertically. Since the two axial ends of the flat key are arc-shaped, the force exerted by the pressure head on the end of the flat key will cause damage to the end of the flat key. damage, and the radial direction of the flat key is difficult to locate, so that there is a certain gap between the flat key and the bottom of the keyway after pressing, making it difficult to connect the output shaft with other parts such as the coupling; at the same time, because the flat key is closely matched with the output shaft Yes, when the flat key is stressed, the output shaft will also be stressed, and the bearing used to fix the output shaft will be affected by the force, and the bearing on the motor end cover or the bearing on the gearbox will be easily damaged
