Description

Technical Field

[0001] This utility model relates to the technical field of claw electrode processing equipment, and in particular to a generator claw electrode chamfering grinding device. Background Technology

[0002] A claw-pole permanent magnet tachogenerator, when its rotor is driven to rotate at a rated speed, outputs an AC electromotive force in which the stator windings are linearly related to the rotational speed. This type of motor is often used as a speed feedback element in control systems. Its characteristics include simple structure, reliable operation, stable performance, suitability for harsh environments, and low manufacturing cost. The structure and working principle of this type of motor differ significantly from traditional tachogenerators. During the forging process, the claw pole requires heating, upsetting, pre-forging, final forging, trimming, annealing, and cold finishing of the raw material. Currently, claw poles are put into use immediately after processing without undergoing involute single-sided chamfering. This leads to distortion of the magnetic field lines during magnetic field changes, resulting in excessive electromagnetic noise and an overly loud engine, negatively impacting the user experience.

[0003] Existing technologies have the following problems:

[0004] After extensive searching, it was found that patent application number CN202020700094.4 discloses a single-sided chamfering claw grinding device for claw electrode production. This patent uses multiple frustum-shaped grinding tools to perform rapid and efficient processing on multiple claw feet of the claw electrode, and uses a collection box to collect and reuse coolant. However, the above patent still has some problems in actual use. The most obvious problem is that the machine needs to be stopped when picking up and putting down the claw electrode, which wastes a lot of time and affects the chamfering grinding efficiency of the claw electrode.

[0005] To address these shortcomings, we proposed a generator claw pole chamfering grinding device. Utility Model Content
