Description

Rotor automatic deburring device

technical field

The utility model belongs to the technical field of motor equipment, and relates to a motor rotor processing device, in particular to an automatic rotor deburring device.

Background technique

The motor rotor is the rotating part in the motor. The motor consists of two parts, the rotor and the stator. It is used to realize the conversion device between electrical energy and mechanical energy and mechanical energy and electrical energy. The motor rotor is divided into the motor rotor and the generator rotor. The stator or rotor punching piece is a stamping part that is stamped by the rotor punching die. The punching piece just punched out has many burrs on the surface of the stripping direction; these burrs affect the stacking of many stator and rotor punching pieces in the assembly of the motor. Therefore, the removal of burrs is an important step in the motor production process. The traditional grinding device does not have a grinding device suitable for the rotor, and manual grinding is used manually, which makes the grinding efficiency low, the labor intensity is high, and the deburring efficiency is low. However, the deburring effect is unstable due to the change of the manual pressure with time. .
