Automatic groove cleaning machine for motor stator inner groove

Abstract

The invention belongs to the technical field of motor maintenance and particularly relates to an automatic groove cleaning machine for a motor stator inner groove. The automatic groove cleaning machine is composed of a bidirectional left pneumatic supporting rod, a bidirectional right pneumatic supporting rod, a rotation support, a longitudinal moving device, a radial moving device, a groove removing electric drill and an electric control device. The rotation support is composed of a left fixing sleeve, a left rotating shaft, a left baffle, a longitudinal linear rail, a longitudinal rack, a right baffle, an electric indexer and a right fixing sleeve. The longitudinal moving device is composed of a sliding block, a drive support, a drive box, a longitudinal drive motor and a longitudinal drive gear. The radial moving device is composed of a radial rack, an end head frame, a connecting plate, a clamping plate, an adjusting fastening ring, a radial drive motor and a U-shaped pressing plate. A groove cleaning drill bit of the automatic groove cleaning machine has freedom degrees in several directions including the longitudinal direction, the radial direction and the circumferential direction, any part in the motor stator inner groove can be cleaned, the work process is automatic, the trouble of manual work is solved, and the effect is improved by several times.

Description

technical field [0001] The invention belongs to the technical field of motor maintenance, and in particular relates to an automatic slot cleaning machine for an inner slot of a motor stator. Background technique [0002] The AC motor is mainly composed of a stator and a rotor. The stator is a cylindrical barrel-shaped structure with grooves on the inner surface for installing stator coils. The stator coils are wrapped by insulating materials in the grooves and sealed with insulating varnish to play a role. Insulation, fixation, and dustproof functions. There are often motors that are damaged due to burnt stator coils. The high temperature when the stator coils are burned causes oxidative denaturation of insulating varnish and insulating materials, and also makes the stator coils form residual dirt such as metal oxides and metal particles. This residual dirt is hard, poisonous, and has strong adhesion, and it is attached to the wire groove of the stator, so it is difficult t...
