Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stator PIN wire welding, in particular to a laboratory welding tool for motor stator PIN wires. Background Art
[0002] In the manufacturing process of flat-wire motors, welding the stator PIN wires is a critical step. Stator PIN wire welding methods primarily include laser welding and resistance welding. Both laser welding and resistance welding offer advantages in terms of high speed and efficiency. However, resistance welding can result in significant metallographic changes in the heat-affected zone (HAZ), potentially degrading the PIN wire's mechanical properties. Laser welding, on the other hand, minimizes heat requirements, resulting in minimal metallographic changes and deformation in the HAZ.
[0003] Laser welding of stator PIN wires also requires clamping two PIN wires together to ensure a tight fit between their connecting ends. These ends are then laser welded using laser welding equipment. Common clamping devices, such as vises, are inconvenient for simultaneously clamping multiple PIN wires and can typically only clamp one group at a time, meaning only one group can be welded at a time. While welding a single stator PIN wire is efficient, laser welding multiple groups is less efficient. Utility Model Content

On the top, the second clamping block 9 is located on the second slide bar 7; an extension plate 10 is provided on the upper part of the mounting beam 3, and the extension plate 10 extends toward the side of the mounting beam 3 away from the column 2, and an abutting beam 11 is provided below the end of the extension plate 10 away from the column 2; a third slide bar 12 is provided on the abutting beam 11 for sliding along the arrangement direction of the multiple placement grooves 5, one end of the third slide bar 12 extends to the side of the abutting beam 11 close to the mounting beam 3 and is provided with a third clamping block 13, and a fourth clamping block 14 is provided on a side wall of the abutting beam 11 close to the mounting beam 3; the first clamping block 8, the second clamping block 9, the third clamping block 13 and the fourth clamping block 14 are arranged in a straight line in sequence, and the first clamping block 8, the second clamping block 9, and the third clamping block 13 are used to clamp the three groups of PIN wires at intervals when they slide close to the fourth clamping block 14; a driving member is provided on the column 2, and the driving member is used to drive the first slide bar 6 and the first clamping block 8 to slide toward the direction of the fourth clamping block 14.

[0024] In this solution, when multiple groups of stator PIN wires need to be laser welded, three groups of PIN wires can be placed in the corresponding three groups of placement slots 5, so that the upper ends of two PIN wires in the three corresponding placement slots 5 can be connected, and the first clamping block 8, the second clamping block 9, the third clamping block 13 and the fourth clamping block 14 respectively clamp one group of PIN wires at intervals, and then the connection ends of the upper ends of the three groups of PIN wires are laser welded respectively by laser welding equipment. Multiple groups of PIN wires can be laser welded at the same time, which is beneficial to improving the efficiency of laser welding multiple groups of PIN wires.
[0025] Example 2
[0026] Based on Example 1, in this example, Figure 2 、 Figure 3 A first slide groove 15 is provided on one side wall of the mounting beam 3 close to the abutting beam 11. One end of the first slide bar 6 is located in the first slide groove 15 and slides with the first slide groove 15. A notch 16 is provided in the bottom wall of the first slide groove 15.

Rotate the driving bolt 18 to move the driving bolt 18 toward the direction close to the vertical rod 17. The driving bolt 18 pushes the vertical rod 17, the first slide bar 6 and the first clamping block 8 toward the direction close to the fourth clamping block 14, so that the first clamping block 8, the second clamping block 9 and the third clamping block 13 all move closer to the fourth clamping block 14, thereby clamping and fixing the three groups of PIN wires by the corresponding clamping blocks. This solution is more convenient for clamping or unclamping the PIN wires.

[0032] Based on Example 1, in this example, Figure 1 、 Figure 2 Both placement beams 4 are removably provided with limit pressure plates 26, which press onto the multiple placement slots 5 on the corresponding placement beams 4. After the three sets of PIN wires are placed in the corresponding placement slots 5, the limit pressure plates 26 are pressed onto the placement beams 4. The limit pressure plates 26 are connected to the placement beams 4 via bolts, so that the limit pressure plates 26 compress and limit the position of the PIN wires. This prevents the PIN wires from vertically shifting and thus affecting the docking of the upper ends of the PIN wires. However, since the PIN wires are made of copper, this does not affect the short-distance horizontal displacement and bending of the PIN wires caused by the sliding of the multiple clamps.

It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model.
