Equal feeding quantity type automatic worm polishing mechanism

Abstract

The invention discloses an equal feeding quantity type automatic worm polishing mechanism. The equal feeding quantity type automatic worm polishing mechanism comprises a workbench (1), a worm polishing device (11) and a worm clamping device (3), wherein the angle defined by the inclined worm clamping device and the worm polishing device corresponds to the tooth-shaped spiral angle of a worm required to be polished; the worm polishing device is mounted on a sliding base (4); the sliding base is connected with a sliding base motor (5). According to the equal feeding quantity type automatic worm polishing mechanism disclosed by the invention, the feeding quantity is controlled by the sliding base motor, the feeding quantity for each time is equal to the previous feeding quantity plus the polishing consumption quantity, so as to meet feeding conformance for each time; the technological method improves the machining precision of the armature spindle worm to a large extent, finally perfects the whole motor quality control, and meanwhile reduces the labor cost. The automatic polishing mechanism can be widely applied to automobile micromotors such as automobile wiper motors, seat motors and windshield lifting motors.

Description

Technical field [0001] The invention relates to a worm processing equipment, in particular to a worm polishing mechanism. Background technique [0002] At present, micromotors are widely used in automobiles, home appliances and other fields, and armature shaft worms (may be referred to as worms) are important components of micromotors. After the tooth profile of the armature shaft worm is processed, the burr needs to be removed by a polishing wheel polishing method to achieve the matching accuracy with the gear (worm gear). In the well-known worm polishing mechanism and polishing method, the worm and the polishing wheel are clamped in parallel, and the clamping motor and the polishing motor respectively drive the two to rotate in opposite directions and contact to achieve polishing. Since the tooth profile on the worm has a spiral 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 ...

AI Technical Summary

Problems solved by technology

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

And the feed rate of the polishing wheel is manually controlled, the feed rate is inconsistent each time, and the polishing effect of the worm is difficult to control

As a result, it will eventually cause abnormal sound and noise of the motor
