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

The invention provides an armature shaft automatic feeding, swinging and polishing mechanism. The armature shaft automatic feeding, swinging and polishing mechanism comprises a workbench, a feeding sliding table, an armature shaft conveying device, an armature shaft clamping device and an armature shaft polishing device. A material box of the armature shaft conveying device is connected with a fixed step, a feeding power source is arranged on a feeding support and connected with a feeding push plate, a movable step is arranged at the position, corresponding to the fixed step, of the feeding push plate, a push block is arranged at the step top end of the fixed step through a material positioning plate, and the push block is connected with the pushing power source. A chuck of the armature shaft clamping device is connected with a swing frame swing control source through a swing frame, the chuck is connected with a chuck rotating control source, the feeding position of the chuck is connected with a chuck tightening control source, and communicated feeding channels are formed in the chuck and the chuck tightening control source. The machining precision of a worm part of an armature shaft is improved, and abnormal sound generated when a motor works is reduced; meanwhile the labor 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 feeding 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 to...
