Description

Technical Field

[0001] The utility model relates to the technical field of shaft sleeve fixing tooling, in particular to a shaft sleeve fixing tooling for a motor tail shaft. Background Art

[0002] Electric motors are commonly known as motors. Electric motors are mainly used as power sources for electrical appliances or various machines. They are used for work on the motor shaft. In order to facilitate the limitation of the shaft, a sleeve needs to be installed on the outside of the shaft. The sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft and is a component of the sliding bearing. The existing sleeve is usually a tubular metal cylinder, and the shaft is inserted into the sleeve to reduce the friction between the shaft and the sleeve. In the process of making the sleeve, various steps are required, such as testing, stamping, etc. These steps require tooling and fixtures to fix the workpiece in order to complete subsequent operations. General fixtures cannot adapt to different types of sleeves, that is, they correspond one-to-one to the size of the sleeve, and have a small scope of application. Utility Model Content
