Special production equipment for special-shaped commutator and production process of special-shaped commutator

Abstract

Special production equipment for a special-shaped commutator comprises a workbench, a guide plate, a positioning ring used for positioning a commutator segment group, a straining ring bushing used for fixing the commutator segment group, a product fork used for clamping the straining ring bushing in batches, and a driving air cylinder; the workbench is arranged in a semi-surrounding shape; an injection moulding station is arranged in the middle of the workbench; an inspection bench, a mould feeding station and a preheating station are sequentially arranged on the left side of the workbench; a material cake heating device and a burr treatment station are arranged on one side of the right side of the workbench; and the commutator segment group sequentially passes through the inspection bench to detect a reinforcing ring, is conveyed into the straining ring bushing through the guide plate and the mould feeding station, is preheated on the preheating station, is subjected to injection moulding on the injection moulding station, is ejected out of the straining ring bushing through the mould feeding station, and is subjected to burr treatment to obtain a commutator finished product. The special production equipment disclosed by the invention has the advantages of simple structure, reasonable design, small layout space, low working intensity, high working efficiency, low production cost, convenience in commutator production and the like.

Description

technical field [0001] The invention relates to a commutator, in particular to special-purpose production equipment for a special-shaped commutator and a production process thereof. Background technique [0002] Commutators are widely used in electric tools and automobile motors. During production, commutators usually use upper and lower reinforcement rings to reinforce the commutator segments of the commutator, and set spring bushings inside the main body of the commutator. , to improve the mechanical strength and overspeed performance of the commutator; and there is a very important process in the commutator production process called the commutator injection molding process, the commutator injection molding process is to complete the commutation through the injection of bakelite powder There are many related auxiliary processes before and after the injection molding process of the commutator, and these processes consume a lot of man-hours, the operation is complicated and ...

[0002] Commutators are widely used in electric tools and automobile motors. During production, commutators usually use upper and lower reinforcement rings to reinforce the commutator segments of the commutator, and set spring bushings inside the main body of the commutator. , to improve the mechanical strength and overspeed performance of the commutator; and there is a very important process in the commutator production process called the commutator injection molding process, the commutator injection molding process is to complete the commutation through the injection of bakelite powder There are many related auxiliary processes before and after the injection molding process of the commutator, and these processes consume a lot of man-hours, the operation is complicated and loose, the production efficiency is low, and the labor intensity of the workers is high. , and for the special-shaped commutator, since the structure of the commutator segment of the special-shaped commutator is different from that of the ordinary commutator, the commutator body needs to be fixed on the plastic core by a rubber band before production and place reinforcing rings on both ends of the commutator body, and then carry out the subsequent injection molding process, so special production equipment and production processes are required for production
