Armature shaft clamping swing polishing mechanism

Abstract

The invention discloses an armature shaft clamping swing polishing mechanism which comprises a worktable, a feed sliding table, an armature shaft clamping device and an armature shaft polishing device, wherein the armature shaft clamping device comprises a clamping bracket and a chuck (16); the chuck is connected with a swing frame swing control source (11) through a swing frame (17); the chuck is connected with a chuck rotation control source (15); the chuck is connected with a chuck tightening control source (13); feeding channels (18) communicated with each other are formed in the chuck and the chuck tightening control source (13); the armature shaft polishing device comprises a polishing bracket (21) and a polishing wheel; the polishing wheel is connected with a polishing power drive source through a polishing spindle; and the polishing wheel is divided into a cloth polishing wheel (27) positioned on the rear part and a fiber material polishing wheel (29) positioned on the front part. According to the polishing mechanism disclosed by the invention, the polishing accuracy of a worm part of the armature shaft is improved, and abnormal sound during motor operation is reduced; and meanwhile, the manual cost is reduced.

Description

technical field [0001] The invention relates to an armature shaft processing equipment for a motor, in particular to an armature shaft clamping and polishing mechanism. Background technique [0002] At present, micromotors are widely used in fields such as automobiles and home appliances, and the armature shaft (the outer end of which is designed as a worm) is an important component of the micromotor. After the worm tooth-shaped part on the end of the armature shaft is processed, the burrs need to be removed by means of buffing wheel polishing, so as to achieve the matching precision with the gear (worm wheel). The known armature shaft polishing mechanism and its polishing method are that the worm part of the armature shaft and the polishing wheel are clamped in parallel, and the armature shaft clamping motor and the polishing motor respectively drive the armature shaft and the polishing wheel to rotate in the opposite direction to achieve contact. polishing. Because the t...

AI Technical Summary

Problems solved by technology

Since the tooth profile on the armature shaft worm has a helical angle, this parallel clamping method will cause the worm tooth profile to have a large polishing angle on one side and a small polishing angle on the other side, resulting in asymmetrical polishing treatment of the armature shaft worm tooth profile

And the feed rate of the polishing wheel is manually controlled, and each feed rate is purely based on experience, resulting in inconsistency, and the polishing effect of the armature shaft worm is difficult to control

As a result, the motor after assembly is abnormal and noisy
