Background

The magnetic shoe is used as a key component in equipment such as a motor, a generator and the like, and chamfering treatment of the edge of the magnetic shoe has important influence on the performance and the service life of a product. The chamfering can reduce stress concentration at the edge of the magnetic shoe, prevent cracking or abrasion caused by sharp edges in the use process, improve the assembly precision of the magnetic shoe and other parts and improve the operation efficiency of the whole equipment. Therefore, the chamfering of the magnetic shoe is an indispensable process in the processing of the magnetic shoe. At present, the chamfering of the magnetic shoe mainly depends on chamfering machine equipment, and the working principle of the chamfering machine is that the edge of the magnetic shoe is ground through a grinding wheel rotating at a high speed so as to realize the chamfering effect.

However, the conventional chamfering machine for magnetic shoes has the disadvantage that an operator is usually required to manually place the magnetic shoe on a jig and manually apply a pushing force to the magnetic shoe to keep the magnetic shoe in close contact with a grinding wheel during the machining process. The mode of highly relying on manual operation not only increases the labor intensity of operators, but also easily causes unstable chamfering quality due to operation fatigue or uneven force control. Moreover, because the pushing force is required to be continuously applied manually in the chamfering process, the force control of operators is difficult to be consistent, and the contact pressure between the magnetic shoe and the grinding wheel is uneven. Such uneven contact pressure may directly affect chamfering effect, and may cause problems such as inconsistent chamfer size, rough edges, and even edge chipping. In view of the above, the magnetic shoe chamfering machine of the present application is proposed.
