A commutator hook chamfering device

Abstract

The invention relates to the technical field of commutators, in particular to a chamfering device for hooks of a commutator, which includes a machine body. The left and right parts of the machine body are respectively provided with a feeding conveyor belt and an unloading conveyor belt. There is a transfer mechanism between the material conveyor belts, a chamfering hole is provided at the front of the top side of the machine body, a chamfering mechanism is provided at the front side of the top of the machine body, and a positioning mechanism is arranged in the front part of the machine body; the invention rotates the drum at a slow speed, The commutator and the frustum of the cone are relatively rotated, so that the hook of the commutator is effectively snapped into the hook groove of the frustum of the cone, that is, the matching between the hook of the commutator and the hook groove of the frustum of the cone is effectively ensured, and the positioning error, thereby effectively reducing the impact on the chamfering of the commutator hook; at the same time, through the sequential cooperation of the feeding conveyor belt, transfer mechanism, chamfering mechanism, positioning mechanism and unloading conveyor belt, the continuous and automatic adjustment of the commutator hook is realized. Chamfering, improve chamfering efficiency.

Description

technical field [0001] The invention relates to the field of commutators, in particular to a chamfering device for a hook portion of a commutator. Background technique [0002] After the commutator is pressed together with the commutator copper sheet and bakelite powder, the top of the commutator copper sheet is milled to narrow it to form the commutator hook, and then the commutator hook is bent in the next bending process Finally, the welding wire hook of the commutator is formed. Due to machining, sharp corners are inevitably formed at the corners where the outer surface of the hook portion of the commutator meets the left and right sides, and this will obviously affect the subsequent use of the commutator, so the above-mentioned corners need to be chamfered. The currently used methods include polishing with a buffing wheel, rolling with a rolling wheel, and filing with a file, but each hook needs to be chamfered separately, resulting in low processing efficiency.

Problems solved by technology

[0007] In view of the above-mentioned shortcomings existing in the prior art, the present invention provides a commutator hook chamfering device, which can effectively solve certain errors that are prone to occur in the prior art, so that the follow-up commutator hook is not squeezed with the arc. Correspondence of the groove, which in turn affects the problem of chamfering the hook of the commutator
