Description

Technical Field

[0001] The utility model relates to a welding wire clamping tool for a flat wire motor. Background Art

[0002] At present, flat wire motors are widely used in new energy vehicles. During the production process, the stator assembly in the flat wire motor needs to first insert multiple bent flat wires into the stator core, and then weld the ends of the flat wires together by welding. However, due to the uneven positions of the flat wires, it is necessary to use a tool to clamp the flat wires during welding. For example, a Chinese patent with publication number CN214721343U discloses a motor stator flat wire argon arc welding tool, in which each lever is moved by turning a dial, and each rotating clamp is driven to rotate by the lever, so that all the toothed clamps are rotated from a vertical state to a horizontal state to clamp the flat wire. However, although the tool can clamp the flat wire, it has many parts and a complex structure, which brings great difficulties to production and assembly, and thus leads to excessively high production costs.

Specifically, the positions of some flat wires 1 in the stator assembly need to be adjusted, so the line splitting card plate 2 needs to be used to adjust the positions of the flat wires 1. During the production process, the branching card plate 2 is first clamped on the flat wire 1 and part of the flat wire 1 is passed through the corresponding branching groove 9 to constrain the position of the flat wire 1 in the branching groove 9, and then the clamping mechanism is installed. The process of installing the clamping mechanism is as follows: first, the first mounting ring 4 and the second mounting ring 5 are driven to rotate by the driving mechanism, and then the first clamping plate 6 and the second clamping plate 7 are rotated to align the first clamping hole 10 with the corresponding second clamping hole 11; then the flat wire 1 is passed through the second clamping hole 11 and the first clamping hole 10 and the main body seat 3 is assembled and connected to the upper end of the stator core 8.
