Abstract

The invention discloses a pseudo-hook assembly for a motor commutator. The pseudo-hook assembly comprises a pseudo sleeve head and a sheath, wherein the pseudo sleeve head is of a hollow cylindrical structure, a plurality of hooks with upward openings are uniformly arranged at the bottom of an outer wall of the pseudo sleeve, a commutator positioning block is further arranged in an inner cavity ofthe pseudo sleeve head and is arranged at the top of the pseudo sleeve head, the sheath comprises a protection head, a protection neck and a protection wall, the protection neck is arranged between the protection head and the protection wall, the protection wall is also of a hollow cylindrical structure, the pseudo sleeve head sleeves an inner cavity of the protection wall, the external diameterof the pseudo sleeve head is equal to the inner diameter of the protection wall, the hooks are arranged at an outer side of the protection wall, and the height of the pseudo sleeve head is not smallerthan the height of the protection wall. The pseudo-hook assembly disclosed by the invention has the characteristics that the device is simple and is convenient to operate, the rotor is firm in winding, and a line breakage phenomenon of the coil during the winding process is fundamentally prevented; and meanwhile, the device can be used repeatedly, the processing cost is reduced, and the winding quality of a coil winding is also improved.

Description

technical field [0001] The invention relates to processing equipment for motor rotors, in particular to a dummy hook assembly for a motor commutator. Background technique [0002] We know that the motor is composed of two parts, the rotor and the stator. It is used to realize the conversion device of electrical energy and mechanical energy and mechanical energy and electrical energy; and the rotor of the motor is generally composed of a connecting shaft, a rotor core, a commutator and a coil winding. . During the winding process of the existing rotor, hooks are often provided on the side wall of the commutator, so that the coil winding is tightly fixed to the commutator, and then the joint of the coil winding is connected to the commutator. The end is welded and fixed; however, with this structural design, the coil and the commutator are easy to loose after the motor is used for a long time, and the end of the circulator is provided with a hook, which also greatly affects t...
