Abstract

The invention is applicable to the technical field of motor machining, and provides a motor commutator machining turning tool and a machining method. The commutator machining turning tool comprises aturning tool main body and a tool bit; the tool bit is arranged at the end part of the turning tool main body; and the tool bit is arranged to be a positive sharp tool with the angle ranging from 58 degrees to 63 degrees, and the tool included angle R ranges from 0.30 mm + / -0.05 mm to 0.50 mm + / -0.05 mm. The turning tool turns the inter-blade section difference, the commutator surface roughness isimproved, Ra is 0.5-0.7 micros, the number of tool grains is 14-17 bar / mm, and no teeth or burrs exist; and the turning surface roughness conforms to the N4-N6 standard, the contact surface of a carbon brush and a commutator is stable, the electrical loss is small, the roughness with the appropriate number of textures and tool grains is generated, and the running-in quality of the carbon brush and the commutator is directly improved. The labor cost is saved, and the product qualification rate is high.

Description

technical field [0001] The invention belongs to the technical field of motor processing, and in particular relates to a turning tool for processing a motor commutator and a processing method. Background technique [0002] At present, high-power food processors need to have electromagnetic compatibility requirements, and more and more customers must also refer to GB 4343.1-2018 for the implementation of electromagnetic compatibility design requirements for a single motor. Enterprises in the motor industry have accumulated a lot of excellent technology for rotor turning under the given design conditions of the project. Such as durable and wear-resistant diamond turning tool blades, excellent physical and mechanical angle tool support design, extremely small rotor dynamic balance, etc. For the anti-braking brake circuit composed of self-excitation and separate excitation modules in the motor winding itself, that is, the stator winding has a self-excitation and separate excitat...
