[0032] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0033] The present application embodiment provides a welding pressure claw. Figures 1 to 6 The welding pressure claw 100 provided in the embodiment of the present application includes: a mounting portion 110, a lateral extension portion 120 and a pressing portion 130 connected to each other. The mounting portion 110 can be used to connect with a driving mechanism so as to use the driving mechanism to drive the welding pressure claw 100 to move toward or away from the workpiece to be welded. The pressing portion 130 is located below the lateral extension portion 120. The lateral extension portion 120 is provided with a first penetration portion 121. The first penetration portion 121 penetrates the lateral extension portion 120 in a vertical direction. The pressing portion 130 is opposite to the first penetration portion 121 in a vertical direction.

[0034] In this way, in the embodiment of the present application, the pressing portion 130 is located below the lateral extension portion 120, so that the lateral spacing between the pressing portion 130 and the lateral extension portion 120 is small, so that when the pressing portion 130 is subjected to the reaction force applied by the workpiece to be welded, the deformation of the welding claw 100 is small, that is, the bending moment of the lateral extension portion 120 is reduced, so that the pressing effect of the pressing portion 130 on the workpiece to be welded is better, thereby improving the welding quality. In addition, when the welding claw 100 is configured in a laser welding device, the laser emitted by the laser welding device can be emitted from the first penetration portion 121 to the periphery of the area pressed by the pressing portion 130, so that the workpiece to be welded can be welded. Through such a structural solution, the laser optical path is optimized at the same time, energy loss is reduced and complex optical path design is avoided.

[0035] In some embodiments, the first through-hole 121 is a first through-hole provided in the lateral extension portion 120, the first through-hole is a tapered hole, and the opening area of ​​the upper end of the first through-hole is larger than the opening area of ​​the lower end. Figure 4 The first through hole is a structure that is small at the bottom and large at the top. For example, the first through hole is a conical structure that is small at the bottom and large at the top. In this way, it is convenient for the laser to pass from top to bottom.

[0036] In addition, in other embodiments, the first through portion 121 may also be a groove. Figure 1 , the left side wall of the first perforation can be removed. That is, the side wall of the first penetration portion 121 is a non-enclosed structure, so that the laser can also be emitted from the first penetration portion 121 to the periphery of the area pressed by the pressing portion 130, so that the welded parts can be welded.

[0037] refer to Figure 1 and Figure 4 In some embodiments, the pressing portion 130 is provided with a second penetration portion 131, which penetrates the pressing portion 130 in the vertical direction, and the second penetration portion 131 is opposite to the first penetration portion 121 in the vertical direction. In this way, the laser can be sequentially emitted to the surface of the workpiece to be welded inside the second penetration portion 131 through the first penetration portion 121 and the second penetration portion 131, so that the workpiece to be welded can be welded.

[0038] In some embodiments, the second through-hole 131 is a second through-hole provided on the pressing portion 130, the second through-hole is a tapered hole, and the opening area of ​​the upper end of the second through-hole is larger than the opening area of ​​the lower end. Figure 4 The second through hole is a structure that is small at the bottom and large at the top. For example, the second through hole is a conical structure that is small at the bottom and large at the top. In this way, it is convenient for the laser to pass from top to bottom, and the amount of welding slag adsorbed on the second through portion 131 during the welding process can be reduced.

[0041] Specifically, refer to Figure 4In some embodiments, the connecting portion 140 is connected to the second end portion 123 of the lateral extending portion 120 , wherein the second end portion 123 is the end portion of the lateral extending portion 120 that is opposite to the first end portion 122 .

[0042] Specifically, refer to Figure 6 In some embodiments, the connecting portion 140 includes a first sub-portion 141 and a second sub-portion 142. The first sub-portion 141 is connected to the first side portion 124 and the pressing portion 130 of the lateral extension portion 120, respectively, and the second sub-portion 142 is connected to the second side portion 125 and the pressing portion 130 of the lateral extension portion 120, respectively. The lateral extension portion 120 includes a second end portion 123, which is the end of the lateral extension portion 120 that is opposite to the first end portion 122. In the direction from the first end portion 122 to the second end portion 123, the first side portion 124 and the second side portion 125 are located on opposite sides of the lateral extension portion 120.

[0043] Of course, in other embodiments, the connecting portion 140 may include only the first sub-portion 141, and the pressing portion 130 may be connected to the first side portion 124 via the first sub-portion 141. Alternatively, the connecting portion 140 may include only the second sub-portion 142, and the pressing portion 130 may be connected to the second side portion 125 via the second sub-portion 142.

[0044] refer to Figure 3 or Figure 6 In some embodiments, the mounting portion 110 is provided with a mounting hole 111. The mounting hole 111 penetrates the mounting portion 110 along the thickness direction of the mounting portion 110. Furthermore, the mounting hole 111 is a strip hole.
