Stator iron core flattening and inner cavity polishing device for screw lifting type duct machine

Abstract

The invention discloses a stator iron core flattening and inner cavity polishing device for a screw lifting type duct machine. The stator iron core flattening and inner cavity polishing device comprises a base, a ball screw, a lifting plate, a driving motor, a flattening block, a polishing motor and a polishing brush; a fixing rod is welded to the lower side of a sliding plate, and the other end of the fixing rod is fixedly connected with the flattening block; the polishing motor is fixedly mounted in the center of the upper side of the sliding plate; the polishing brush is fixedly mounted atthe lower end of an output shaft of the polishing motor through a coupling; and soft steel wires are evenly distributed on the outer circle of the polishing brush. According to the stator iron core flattening and inner cavity polishing device, the heights of the polishing brush and the flattening block can be adjusted so as to meet inner circle cavity clearing and flattening work of stator iron cores with different stack thicknesses, and thus the universality of the device is greatly improved; and inner circle cavity clearing and flattening work can be conducted simultaneously, the two workingprocedures are integrated, the work efficiency is greatly improved, and the production beat is accelerated.

Description

Technical field [0001] The invention relates to the field of motors, in particular to a device for flattening the stator iron core and internal cavity polishing of a screw rod lifting type air duct machine. Background technique [0002] The stator core is an important component that constitutes the magnetic flux circuit of the motor and fixes the stator coil. It is compressed by punching sheets and various fasteners to form a whole; the thickness of the stator core punching sheet is generally 0.5mm or 0.35mm. Cold rolled silicon steel sheet or iron-nickel soft magnetic alloy sheet punching. If the outer diameter of the punch is less than 1m, use a full-circle punch, and use a fan-shaped punch for those greater than 0.99m. The stator core often needs to be flattened after the stamping is completed, to prevent the stator punch in the stator core from lifting up, and scratching the enameled wire surface paint film when the stator is wound, causing the motor turns and broken wires. ...

AI Technical Summary

Problems solved by technology

The stator core often needs to be flattened after the stamping is completed to prevent the stator punch in the stator core from lifting up, scratching the paint film on the surface of the enameled wire during the winding of the stator, and causing the inter-turn and disconnection of the motor. Clean the cavity of the inner circle of the stator to avoid rusting of the iron core. At present, the motor manufacturers carry out these two processes separately, and use manual cavity cleaning when cleaning the cavity. The effect of cleaning the cavity is poor and the efficiency is not high.
