[0043] See also Figures 1 to 16 The utility model proposes a clamping mechanism and a spot welding machine. The spot welding machine includes an upper shell 1 and a main body 2, and the upper shell 1 is detachably connected to the main body 2. The clamping mechanism is arranged on the front of the upper shell 1. The clamping mechanism includes a first limiting portion 11 and a second limiting portion 12, and the first limiting portion 11 and the second limiting portion 12 are arranged opposite to each other, and a clamping space is formed between the first limiting portion 11 and the second limiting portion 12. When the transplanted battery cell is welded, the battery protection board cable is placed in the clamping space. The battery protection cable is fixed by the first limiting portion 11 and the second limiting portion 12, and will not shake, which facilitates welding.

[0044] In order to adapt to battery protection cables of different specifications, in some embodiments of the present utility model, the clamping mechanism further includes a clamping member 3 and an elastic member 4. A first guide portion 13 is provided on the front of the upper shell 1, one end of the first guide portion 13 is opposite to the first limit portion 11, and the other end of the first guide portion 13 is opposite to the second limit portion 12.

[0045] One end of the elastic member 4 is connected to the clamping member 3 , and the other end of the elastic member 4 is connected to the second limiting portion 12 .

[0046] In the present utility model, the clamping member 3 can slide back and forth between the first limiting portion 11 and the second limiting portion 12 along the length direction of the first guide portion 13 by means of the sliding cooperation between the first guide groove 37 and the first guide portion 13. When the battery protection board cable is placed between the first limiting portion 11 and the clamping member 3, the elastic member 4 supports the clamping member 3 so that it abuts against the battery protection board cable, thereby fixing the position of the battery protection board cable, avoiding the shaking of the battery protection board cable, and facilitating subsequent welding. Preferably, the elastic member 4 is a spring. It can be understood that in some embodiments of the present utility model, the elastic member 4 can also be a spring.

[0047] In order to make the clamping member 3 and the upper shell 1 connected more tightly and prevent the clamping member 3 from shaking during the welding process, causing the battery protection board cable to shake and affect the welding, in the present utility model, see Figure 6 and Figure 7 The upper shell 1 is provided with a first avoidance position 14, which is arranged in the area between the first limiting portion 11 and the second limiting portion 12.

[0048] After the hook 31 is engaged with the edge of the first avoidance position 14, the clamping member 3 can only slide back and forth in the horizontal direction of the upper shell 1 along the length direction of the first guide portion 13. In the vertical direction, the clamping member 3 cannot shake due to the interference between the hook 31 and the upper shell 1, which reduces the degree of freedom of the clamping member 3 in the vertical direction.

[0049] See also Figure 8 and Fig. 9 Since the second limiting portion 12 is arranged on the step formed by the upper shell 1, the vertical plane of the step and the plane where the first guide portion 13 is located adopt an arc transition. In order to keep the clamping member 3 smooth during the sliding stroke, in some embodiments of the utility model, a clamping block 15 is provided on the edge of the first avoidance position 14, and the plane where the clamping block 15 is engaged with the hook 31 is parallel to the plane where the first guide portion 13 is located. The clamping block 15 is arranged on the back of the upper shell 1 and is spaced apart from the first guide portion 13, and the hook 31 is engaged with the clamping block 15. After the hook 31 is engaged with the clamping block 15, the hook 31 slides back and forth along the surface of the clamping block 15 more smoothly.
