Positioning and guiding device for inserting flat wire hairpin into stator

Abstract

The invention discloses a positioning and guiding device for inserting a flat wire hairpin into a stator. The device comprises a fixed bracket, a front guiding device and a rear positioning device, wherein the front guiding device comprises a driving mechanism, a rotating plate, a sliding block plate, a plurality of first sliding blocks stretching out and drawing back in the radial direction of the sliding block plate, and guiding moving sheets fixed to the front ends of the first sliding blocks, the guiding moving sheet is provided with a guiding groove so as to prevent a flat wire hairpin from directly pressing the front end of insulating paper, the rear positioning device comprises a driving mechanism, a rotating plate, a sliding block plate and a plurality of second sliding blocks stretching out and drawing back in the radial direction of the sliding block plate, the front ends of the second sliding blocks are provided with first open grooves and second open grooves, and the firstopen grooves and the second open grooves form blocking shoulders, so that the flat wire hairpin can pass through the blocking shoulders while the insulating paper can be limited from moving in the axial direction. The positioning and guiding device can accurately position the flat wire hairpin in the radial direction and the circumferential direction of the stator, prevents the flat wire hairpin from directly pressing insulating paper in the insertion process, effectively protects the insulating paper, guides the flat wire to enter a stator notch, and guarantees the accuracy of wire insertion.

[0002] With the vigorous development of new energy vehicles, the corresponding demand for motors is increasing, and the performance of the motor determines the performance of new energy vehicles. The traditional round copper wire motor stator winding is popular due to its convenient assembly. For a while, but with the development of higher requirements for motors, motors with smaller volume, stronger functions and faster running speed are required. Compared with ordinary windings, flat wire windings have light weight and high efficiency under the same volume. High and low noise under high voltage; From a technical point of view, under the same size, it can pass through larger currents, adapt to higher frequencies, and obtain higher quality factors. However, due to the difficulty of assembly of flat wire windings, currently It is not widely used in the domestic market

[0003] The flat copper wire motor can greatly increase the full rate of the motor slot, and then improve the performance of the motor. Therefore, more and more flat copper wires are used in the field of motors, but if the installation and processing of the flat copper wire cannot meet the needs of the motor or its processing technology Low precision and high processing difficulty will also lead to a reduction in the production efficiency of the motor, and low precision will greatly reduce the efficiency of the subsequent use of the motor. Therefore, for flat copper wire motors, the effect of flat copper wire installation and processing directly affect the performance of the motor

[0004] In the prior art, in order to protect the insulating paper, manual insertion is often used, which leads to low production efficiency. At the same time, during the process of manual insertion, the insulating paper moves in the stator slot, so that the ends of the insulating paper are not neat
