Technical Field

[0001] The utility model relates to the technical field of motor housing assembly, in particular to a three-station riveting device for a motor housing. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magnetic-electromotive force to rotate the torque. Electric motors are divided into DC motors and AC motors according to the power supply used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors. The electric motor is mainly composed of a stator and a rotor. The direction of the force on the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines. The working principle of the electric motor is that the magnetic field acts on the force on the current, causing the motor to rotate.

[0003] At present, the existing motor housings are usually riveted together manually, and the working process is: two motor housings are abutted together, and the connecting holes of the two motor housings are aligned, and multiple rivets are inserted into the connecting holes of the two motor housings, and the rivets are deformed by knocking, so that the two motor housings are riveted together.
