Two-way type armature shaft automatic polishing device

Abstract

The invention discloses a two-way type armature shaft automatic polishing device. The two-way type armature shaft automatic polishing device comprises a polishing support (21) and polishing wheels; and the polishing wheels are connected with a polishing power driving source (26) through a polishing central spindle (22), the polishing wheels are divided into a material distributing polishing wheel (27) located at the back portion and a fiber material polishing wheel (29) located at the front portion. The upper portion of the material distributing polishing wheel (27) is connected with an extrusion block (24) in a wax box and a wax extruding assembly (28) through the wax box (23). According to the two-way type armature shaft automatic polishing device, the fiber material polishing wheel and the material distributing polishing wheel are adopted for conducting burr removing and wax coating polishing two-way type treatment on a worm part of an armature shaft, as a feeding sliding table is controlled by a sliding table power source, the polishing loss amount is added during feeding each time on the basis of polishing last time, and the feeding amount each time is uniform. The polishing machining accuracy of the worm part of the armature shaft is improved, and abnormal sounds generated when a motor works are reduced.

Description

technical field [0001] The invention relates to an armature shaft processing equipment for a motor, in particular to an armature shaft polishing device. 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 tooth profile on ...

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
