A positioning guide 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, which comprises a fixed bracket, a front guiding device and a rear positioning device. A plurality of sliding blocks 1 and a guide moving piece fixed on the front end of the sliding block 1, wherein the guiding moving piece has a guide groove to prevent the flat wire hairpin from directly pressing against the front end of the insulating paper, and the rear positioning device includes a driving mechanism, a rotating plate, a sliding A block plate, and several sliding blocks 2 that expand and contract in the radial direction of the slider plate, wherein the front ends of the sliding block 2 have opening slot 1 and opening slot 2, and the two form shoulders to limit the insulating paper while allowing the flat wire hairpin to pass through. Axial movement. The positioning guide device can accurately locate the flat wire hairpin in the radial and circumferential directions of the stator, avoiding the flat wire hairpin from being directly pressed against the insulating paper during the insertion process, and guiding the flat wire into the slot of the stator while effectively protecting the insulating paper. Ensure the accuracy of wiring.

[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
