Motor stator slot-sealing mechanism and motor stator slot-sealing machine

Abstract

The invention belongs to the technical field of motor machining and discloses a motor stator slot-sealing mechanism and a motor stator slot-sealing machine. The motor stator slot-sealing machine comprises a frame, a slot wedge paper carrier disc, a slot-sealing mechanism, and a stator support mechanism, wherein the slot wedge paper carrier disc, the slot-sealing mechanism, and the stator support mechanism are disposed on the frame. The slot-sealing mechanism comprises a paper feeding device for pulling slot wedge paper strips out of a slot wedge paper roll and feeding the slot wedge paper strips downwardly, a cutting-off device for cutting off the slot wedge paper fed by the paper feeding device, a molding device for extrusion molding the cut-off unformed slot wedge paper, and a slot wedge inserting device for pushing formed slot wedge paper out of the molding device and inserting the slot wedge paper into the sealed motor stator slot. The slot-sealing machine achieves automation of slot wedge paper insertion by designing the paper feeding device, the cutting-off device, the molding device, and the slot wedge inserting device in a combined way. The motor stator slot-sealing mechanism and the motor stator slot-sealing machine are compact in overall structure, simple in operation, and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of motor processing, and relates to motor stator processing equipment, in particular to equipment for sealing motor stator winding slots. Background technique [0002] Existing motor stators are usually sealed with bamboo wedges, epoxy plate slot wedges or injection molded slot wedges. The first two kinds are not conducive to the automation of inserting wedges, while the ordinary injection molding slot wedges limit the insulation level of the motor below class B, and the use of high temperature injection molding slot wedges will increase the cost significantly. Compared with the above three kinds of slot wedges, the method of sealing the motor stator with rolls of slot wedge paper as the raw material is not only easy to ensure that the insulation level of the motor is F level and above, but also the cost is significantly lower than ordinary Injection molded wedges. But, also do not have at present the slot...
