DETAILED DESCRIPTION

[0018] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-3 As shown, a clamp for processing lithium batteries includes: a base plate 1, a fixing plate 2 is symmetrically fixedly connected to the upper end surface of the base plate 1, and a first threaded rod 6 is threadedly connected to the two fixing plates 2. An arc-shaped clamping block 10 is symmetrically slidably arranged above the base plate 1, and the two arc-shaped clamping blocks 10 cooperate with each other to clamp the round lithium battery.

[0020] The number of the first threaded rods 6 corresponds one to one with the number of the arc-shaped clamping blocks 10. The arc-shaped clamping blocks 10 are fixedly connected with connecting blocks 7 near the curved surfaces of the corresponding first threaded rods 6. The connecting blocks 7 are integrally formed with the arc-shaped clamping blocks 10. The side surfaces of the connecting blocks 7 are rotatably connected to one end of the corresponding first threaded rods 6.

[0021] The first threaded rod 6 is rotated, and the first threaded rod 6 drives the corresponding connecting block 7 and the arc-shaped clamping block 10 to move left and right along the length direction of the first threaded rod 6 as a whole.

[0022] The two sides of the arc-shaped clamping block 10 are matched and fixedly provided with fixing blocks 5 . The position of the arc-shaped clamping block 10 is fixed relative to the two fixing blocks 5 , and the arc-shaped clamping block 10 can slide above the bottom plate 1 together with the fixing blocks 5 .

[0023] The fixed block 5 is slidably arranged above the base plate 1. Specifically, the lower end surface of the fixed block 5 is fixedly connected with a slide rod 4. A slide groove 3 is provided at the upper end of the base plate 1 and corresponding to the position of each slide rod 4. The slide rod 4 is slidably arranged inside the slide groove 3.

[0024] The fixed blocks 5 that are fixedly arranged on both sides of the arc-shaped clamping block 10 are further explained as follows: connecting frames 8 are symmetrically fixedly connected to both sides of the connecting block 7 , and one end of the connecting frame 8 away from the connecting block 7 is fixedly connected to the fixed block 5 .

[0025] A double-headed screw rod 9 is rotatably connected between the two fixed blocks 5 , one end of the double-headed screw rod 9 is rotatably connected to the side surface of one of the fixed blocks 5 , and the other end of the double-headed screw rod 9 passes through the other fixed block 5 and is fixedly connected to a handle 12 .

[0026] A notch 11 is formed on the arc-shaped clamping block 10 . The notch 11 is arranged parallel to the bottom plate 1 , and the double-headed screw rod 9 passes through the notch 11 .

[0027] The two ends of the outer surface of the double-headed screw rod 9 are respectively provided with threads of opposite rotation directions, and the two ends of the outer side of the double-headed screw rod 9 are threadedly connected with rectangular clamping blocks 13. There are four rectangular clamping blocks 13 on the two double-headed screw rods 9, and the four rectangular clamping blocks 13 cooperate with each other to clamp the square lithium battery.

[0028] The rectangular clamping block 13 is slidably connected to the side of the arc clamping block 10 with a limiting block 15. Specifically, a rectangular opening 14 is opened on the rectangular clamping block 13, and the limiting block 15 is slidably set at the rectangular opening 14. The side of the limiting block 15 away from the arc clamping block 10 is fixedly connected with a second threaded rod 16. The second threaded rod 16 passes through the rectangular opening 14 and extends to the outside of the rectangular clamping block 13. A nut 17 is threadedly connected to the second threaded rod 16.

[0029] Working principle:

[0030] When the round lithium battery needs to be clamped and fixed, the round lithium battery is placed between the two arc-shaped clamping blocks 10, and the two first threaded rods 6 are rotated. The first threaded rods 6 drive the corresponding connecting blocks 7 and the arc-shaped clamping blocks 10 to move as a whole along the length direction of the first threaded rods 6, and the two arc-shaped clamping blocks 10 gradually approach each other to clamp the round lithium battery.

[0031] When the square lithium battery needs to be clamped and fixed, the square lithium battery is also placed between the two arc-shaped clamping blocks 10, and the two handles 12 are rotated at the same time. The handles 12 drive the double-headed screw 9 to rotate, so that the two rectangular clamping blocks 13 on the double-headed screw 9 are close to each other until the distance between the two rectangular clamping blocks 13 on the same mechanism matches the width of the square lithium battery, so that the length direction of the square lithium battery perpendicular to the bottom plate 1 is its width direction, and the length direction of the square lithium battery parallel to the bottom plate 1 is its length direction; then adjust the distance between the two aligned limit blocks 15 in different mechanisms according to the length of the square lithium battery: slide the limit block 15 in the rectangular opening 14, and then rotate the nut 17 to fix the position of the limit block 15, and then rotate the first threaded rod 6, the first threaded rod 6 drives the corresponding connecting block 7 and the arc-shaped clamping block 10 to move as a whole along the length direction of the first threaded rod 6, and the two aligned limit blocks 15 on different mechanisms are close to each other until the two limit blocks 15 are simultaneously attached to the side of the square lithium battery to clamp and fix it.

[0032] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
