External shaping device of motor winding group

Abstract

The invention discloses an external shaping device of a motor winding group. The external shaping device comprises an organic rack and a bottom plate, wherein a shaping mechanism is arranged on an upper surface of the bottom plate, the shaping mechanism comprises a round groove, the round groove is formed in the upper surface of the bottom plate, a round through is formed in a middle part of the round groove, a plurality of linear sliding grooves are arranged in the round groove, sliding blocks are arranged in the linear sliding grooves, an annular groove disc is arranged in the round groove,the sliding block is clamped between the annular groove disc and the linear sliding groove, a plurality of arc grooves are formed in the annular groove disc, a push block is connected with one end ofeach sliding block, an upper surfaces of the upper end of each sliding block is connected with a bearing, the bearing is rotatably embedded into the corresponding arc groove, an inner arc surface is arranged at an inner side of each push block, the inner arc surfaces of the push blocks can encircle to form a round shape, and the annular groove disc is driven to rotate by an air cylinder. By the external shaping device of the motor winding group, external shaping is performed on the motor winding group, the motor assembly quality is ensured, the winding group shaping efficiency and mechanical and automatic degree of motor production are improved, and labor cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of motor production equipment, and in particular relates to an external shaping device for a motor winding group. Background technique [0002] There are many types of motors, and the winding group forms and winding processes are different. First insert the hairpin-type wire strip on the wire insertion tool to form a winding, and then transfer the winding to the stator of the motor. This method can improve the winding efficiency, facilitate the mechanization and automation of the winding, and is a relatively advanced motor winding process. However, with the winding formed in this way, the winding is prone to slipping between adjacent hairpin-type wire bars during the process of inserting the wire and taking it out of the inserting tooling. Group precision requirements. At present, for the shaping of the motor winding group, most of them are purely manual shaping. In the shaping process, the shaping of the...

However, with the winding formed in this way, the winding is prone to slipping between adjacent hairpin-type wire bars during the process of inserting the wire and taking it out of the inserting tooling. group precision requirements

At present, for the shaping of the motor winding group, most of them are purely manual shaping. In the shaping process, the shaping of the winding end is not in place, and the size of the stator winding end cannot be guaranteed, and the height of the stator winding end cannot be guaranteed. This not only It affects the performance of the motor, and the production efficiency is extremely low, and the worker's operation is also relatively complicated
