Large-scale stator winding, embedding and expanding all-in-one machine

Abstract

The invention relates to the technical field of motor assembly, in particular to a large stator winding, embedding and expanding all-in-one machine which comprises a whole machine frame, a working platform is arranged at the top of the whole machine frame, a supporting column is fixedly connected to the lower of the working platform through an adjusting device, and a controller and a movable guiderail are arranged on the working platform. A winding part, an assembling part, an expanding part and a lifting part are sequentially arranged at the bottom of the whole machine frame, a guide grooveis formed in the side face of the lifting part and matched with the movable guide rail, the winding part comprises a winding nozzle and a winding die arranged overthe assembling part, and the expanding part comprises a lifting motor and an expanding head fixedly connected to the top of the lifting motor. The functions of paper feeding, wire embedding, die head conversion, coil arrangement, statorrotation and the like in the stator assembling process are integrated in one machine, apaper feeding part of the novel design is high in conversion efficiency, and manual operation is not needed.

Description

technical field [0001] The invention relates to the technical field of motor assembly, in particular to a large stator winding, embedding and expanding integrated machine. Background technique [0002] Insulation paper and slot cover paper are often used in stator assembly. Since the lengths of the insulation paper and slot cover paper are different, it is often necessary to install the insulation paper and slot cover paper into the stator slot in two steps. As far as the traditional method is concerned, it is necessary to manually insert the insulating paper into the stator slot, then repeat the above-mentioned actions, and then insert the slot cover paper into the stator slot. On the one hand, manual insertion of slot cover paper and insulation paper is inefficient and has a high error rate, which eventually leads to a high rate of stator defective products; on the other hand, the installation of slot cover paper and insulation paper is divided into two steps, and the requ...

AI Technical Summary

Problems solved by technology

On the one hand, manual insertion of slot cover paper and insulation paper is inefficient and has a high error rate, which eventually leads to a high rate of stator defective products; on the other hand, the installation of slot cover paper and insulation paper is divided into two steps, and the required The time is also longer, directly slowing down the production time, resulting in a reduction in production efficiency

Furthermore, even if the insulating paper and the slot cover paper are loaded into the stator slot by mechanical means, the traditional method also needs to put the cut insulating paper and the slot cover paper into the mold first, and then move the mold to install the insulating paper and slot cover paper. In the machine of slot cover paper, it is time-consuming and laborious, with low work efficiency and low degree of automation

The invention patent with the application number CN201822005255.3 discloses a paper embedding device for stators, the purpose of which is to embed insulating paper into the stator at one time. It can realize one-time assembly of insulating paper and slot cover paper, and can only embed insulating paper of uniform length into the stator, which has certain limitations in terms of paper embedding equipment

[0003] At the same time, in the large-scale assembly process, the stator is usually not assembled and formed at one time. In general assembly, it is necessary to assemble one side of the stator and then rotate the stator to a certain angle, and then assemble the other sides of the stator. This work is often done manually by the staff, which is time-consuming. laborious, low work efficiency

[0004] Finally, the height adjustment of the traditional stator assembly machine is usually controlled by the cylinder, which consumes a lot of energy, and the cylinder control has certain uncertainty, low reliability, and high failure rate
