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

Abstract

An armature shaft feeding swing clamping mechanism comprises a workbench, a feeding sliding table, an armature shaft conveying device and an armature shaft clamping device. A material box of the armature shaft conveying device is connected with a fixed step. A feeding power source is installed on a feeding support. The feeding power source is connected with a feeding push plate. A movable step is installed in the position, corresponding to the fixed step, on the feeding push plate. A pushing block is installed at the top end of the fixed step through a material positioning plate. The pushing block is connected with a pushing power source. A chuck of the armature shaft clamping device is connected with a swing frame swinging control source through a swing frame. The chuck is connected with a chuck rotation control source. The feeding position of the chuck is connected with a chuck contracting control source. The chuck and the chuck contracting control source are provided with feeding channels which communicate with each other. According to the armature shaft feeding swing clamping mechanism, the machining precision of a worm part of an armature shaft is improved, and abnormal noise generated during working of a motor is reduced; and 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 clamping 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 too...
