Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to a riveting device used for motor processing. Background Art

[0002] A motor is an electrical device that converts electrical energy into mechanical energy. The basic structure of a motor consists of a stator and a rotor, of which the stator is the stationary part and the rotor is the rotating part. The working principle of the motor is based on electromagnetic induction. The current generates a magnetic field between the stator and rotor, which generates torque to rotate the rotor. During motor processing, a riveting machine is required to fix the motor casing and sleeve together. First, the motor casing and sleeve are correctly positioned together and firmly fixed with a clamp or other tool. Holes are drilled in the metal parts to be connected. The diameter and position of the holes are determined by the size and shape of the rivets used. The rivets are then inserted into the holes. The riveting machine applies axial force to the rivets, causing them to be thickened in the rivet hole and form a nail head, thus connecting the motor casing and sleeve.

[0003] During the riveting process between the motor housing and the shaft sleeve, the arc-shaped structure of the motor's outer periphery causes irregularities in the contact surface, which may lead to uneven distribution of riveting force. After riveting, the motor housing and the shaft sleeve may be deformed due to extrusion, especially in the arc-shaped part, which will affect the subsequent assembly of the product.

[0004] In order to solve the above problems, this application proposes a riveting device for motor processing. Utility Model Content
