Commutator segment for commutator and production equipment of commutator segment

Abstract

The invention discloses a commutator segment for a commutator and production equipment of the commutator segment and belongs to the technical field of commutators. The invention aims to solve the problem that bulges and burrs are generated due to the fact that two sides of the hook part of a commutator segment are extruded outwards under pressure in a hooking process. The commutator segment is characterized in that the commutator segment comprises a segment body and a hook par; the segment body comprises a contact block and a clamping block; the contact block is provided with a connecting block in the length direction of the contact block; the connecting block is provided with a connecting sheet in the vertical direction of the connecting block; one end, far away from the contact block, ofthe connecting sheet, is fixedly connected with the clamping block in the length direction of the connecting sheet; the contact block, the connecting block, the connecting sheet and the clamping block are fixedly connected with one another; two ends of the connecting block, two ends of the connecting sheet and two ends of the clamping block jointly clamping grooves; one end of the contact block in the length direction of the contact block is fixedly connected with the hook part; deformation grooves are formed in two ends of the hook part in the width direction of the hook part; and the two deformation grooves penetrate through the upper end surface and the lower end surface of the hook part. With the commutator segment for the commutator and the production equipment of the commutator segment of the invention adopted, the problem that bulges and burrs are generated due to the fact that two sides of the hook part of a commutator segment are extruded outwards under pressure in a hookingprocess can be solved.

Description

technical field [0001] The invention relates to the technical field of commutators, in particular to a commutator segment for a commutator and production equipment thereof. Background technique [0002] The commutator is a component used for current commutation on DC motors and AC series motors in order to allow the motor to continue to rotate, commonly known as a commutator. Structurally, the commutator is a circle surrounded by several commutator segments, which are respectively connected to each tap on the rotor, and two electrodes connected to the outside are called brushes to contact it, and only two of them are in contact at the same time. The principle is that when the coil passes through the current, it will rotate through the attraction and repulsion force under the action of the permanent magnet. The brushes are separated, and the brushes are connected to the contacts corresponding to the set of coils that produce the driving force. Commutator segments are genera...

Problems solved by technology

[0003] The commutator piece of the existing hook-type commutator is in front of the hook, and the two sides of the hook part of the commutator piece are straight, and the two sides of the hook part of the commutator piece are squeezed when bending, and then the two sides extend outward Protrusions, wrinkles and burrs, etc., will easily damage and cut the enameled wire during the hooking process, cause the bare copper of the enameled wire to oxidize, and the load current density will be uneven during power-on, which will affect the rectification quality of the motor and shorten the service life of the motor. life
