Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The twisting of the flat wire winding in this embodiment is to attach the figure 1 The straight flat wire in the twisted into attached figure 2 The bent flat wires in the figure 2 The bent-shaped structure in , must produce relative displacement along the axial direction during the torsion process.

[0032] Such as Figure 3-5 As shown, it is a schematic structural diagram of the twisting device of this embodiment, including a base plate 1 and a cover plate 2 fixed on the base plate 1 , and the cover plate 2 is located on the base plate 1 and is hollow between the two. On the cover plate 2, there are not only outer layer torsion disks 3 and inner layer torsion disks 4 for torsion, such as image 3 As shown, the inner twisting disc 4 and the outer twisting disc 3 are circular bowl-shaped structures nested together. Groove...

Abstract

The invention relates to the technical field of electric motors for new energy automobiles, in particular to a compound torsion device and a torsion method for motor flat wire windings. It also includes an outer layer torsion disk and an inner layer torsion disk arranged coaxially; a torsion drive mechanism for driving the outer layer torsion disk and the inner layer torsion disk to rotate around the axial direction is arranged between the cover plate and the bottom plate; The layer torsion disk is located on the cover plate, and an axial drive is arranged between the cover plate and the outer layer torsion disk to drive the outer layer torsion disk and the inner layer torsion disk to move axially when the outer layer torsion disk and the inner layer torsion disk rotate around the axis mechanism. The twisting device of the present invention is simple in structure and easy to operate. By increasing the axial movement during the twisting process, it can accurately complete the end of the flat wire and deny the design twisting requirements. The twisting precision is high and has great promotion value.

Description

technical field [0001] The invention relates to the technical field of electric motors for new energy automobiles, in particular to a compound torsion device and a torsion method for motor flat wire windings. Background technique [0002] Flat wire motors are more and more widely used because of the high motor slot full rate, which in turn increases the power density of the motor, and is beneficial to reduce copper consumption and temperature rise. However, if the processing and manufacturing of the flat wire cannot meet the needs of the motor or the processing precision is not high and the processing difficulty is high, it will also lead to a reduction in the production efficiency of the motor, and the low precision will greatly reduce the efficiency of the subsequent use of the motor. Therefore, for flat wire motors, the effect of flat wire processing and manufacturing directly affects the performance of the motor. The current flat wire processing device can realize doubl...
