[0020] 1. This utility model, by providing a clamping assembly, places the power battery body on the placement platform. Turning on the clamping motor drives the gear to rotate under the action of the limiting rod. Under the action of meshing with the toothed plate, the gear moves the U-shaped frame and guide post. Then, under the limiting post's control and the rotation of the movable post, the sleeve rod rotates, causing the movable clamping rod to move in the opposite direction to the U-shaped frame. The movement of the movable clamping rod is buffered and limited by the spring and the limiting post, thereby causing the movable clamping rod and anti-slip pad to move towards the outer wall of the power battery body. This facilitates the clamping and fixing of power battery bodies of different sizes under the action of the fixed clamping rod.

[0021] 2. This utility model incorporates a detector and a moving component. Under the action of the detector, the model of the power battery body is detected. The moving motor is activated, driving the threaded rod to rotate on the inner wall of the bracket. This, in turn, drives the threaded slider to move within the bracket under the guidance of the guide rod. This, in turn, moves the placement platform and the power battery body at its top to the corresponding test needle. The controller is then activated to test the performance of the power battery. The sliding rod at the bottom of the placement platform slides within the first sliding groove, which facilitates stable support for the movement of the placement platform and the power battery body, thereby improving the efficiency of power battery body performance testing.

Both ends of the U-shaped frame 705 are movably sleeved on the right side of the housing. A guide mechanism is located on the left side of the U-shaped frame 705 and is used to move the U-shaped frame 705 within the housing. The guide mechanism includes a clamping motor 701, with a gear 702 fixedly connected to the transmission end of the clamping motor 701. A limiting rod 704 is movably sleeved on the middle of the gear 702 via a bearing. One end of the limiting rod 704 is fixedly connected to the outer wall of the U-shaped frame 705. A toothed plate 703 meshes with the outer wall of the gear 702. One end of the toothed plate 703 is fixedly connected to the bottom end of the housing.

Then, under the limiting post 711 and the rotation of the movable post 706, the sleeve rod 710 rotates, which can drive the movable clamping rod 712 to move in the opposite direction to the U-shaped frame 705. Under the action of the spring 707 and the limiting post 711, the movement of the movable clamping rod 712 is buffered and limited, which in turn drives the movable clamping rod 712 and the anti-slip pad 713 to move towards the outer wall of the power battery body 6. Specific Implementation Example 2

[0032] Please see Figure 1 and Figure 4 Based on the first specific embodiment, it also includes a moving component 8, which is disposed between the workbench 4 and the placement platform 9, and is used to drive the placement platform 9 and the power battery body 6 to move. The moving component 8 includes: a bracket 803, which is fixedly connected to the inner wall of the second slide groove 402. A threaded slider 802 is slidably sleeved on the inner wall of the bracket 803. The top end of the threaded slider 802 is fixedly connected to the bottom end of the placement platform 9. Slide rods 11 are fixedly connected to the four corners of the bottom end of the placement platform 9. The outer walls of the four slide rods 11 are slidably connected to the first slide groove 401; and a driving mechanism. The drive mechanism is located at the threaded slider 802 and is used to drive the threaded slider 802 to move within the bracket 803. The drive mechanism includes a moving motor 801. The outer wall of the moving motor 801 is fixedly connected to the right side of the worktable 4. The transmission end of the moving motor 801 passes through the worktable 4 and the bracket 803 and is fixedly connected to a threaded rod 805. The outer wall of the threaded rod 805 is threadedly sleeved with the middle part of the threaded slider 802. Guide rods 804 are movably sleeved near both sides of the threaded slider 802. The two ends of the two guide rods 804 are fixedly connected to the inner wall of the bracket 803.

[0033] Specifically: Turn on the moving motor 801, which drives the threaded rod 805 to rotate on the inner wall of the bracket 803. This causes the threaded slider 802 to move within the bracket 803 under the guidance of the guide rod 804. This, in turn, moves the placement platform 9 and the power battery body 6 at its top to the corresponding test needle. Then, turn on the controller 1 to test the performance of the power battery. The slide rod 11 at the bottom of the placement platform 9 slides within the first slide groove 401.

[0034] The working principle of this utility model is as follows: The main body 6 of the power battery is placed on the placement platform 9. The clamping motor 701 is turned on, driving the gear 702 to rotate under the action of the limiting rod 704. Under the action of meshing with the toothed plate 703, the U-shaped frame 705 moves against the guide post 708. Then, under the limiting of the limiting post 711 and the rotation of the movable post 706, the sleeve rod 710 rotates, which in turn drives the movable clamping rod 712 to move in the opposite direction to the U-shaped frame 705. The spring 707 and the limiting post 711 buffer and limit the movement of the movable clamping rod 712, thereby driving the movable clamping rod 712 to move against the anti-slip pad 7. 13 moves towards the outer wall of the power battery body 6. Under the action of the fixed clamping rod 714, it clamps and fixes the power battery bodies 6 of different sizes. The moving motor 801 is turned on, which drives the threaded rod 805 to rotate on the inner wall of the bracket 803. This drives the threaded slider 802 to move within the bracket 803 under the guidance of the guide rod 804. This then drives the placement platform 9 and the power battery body 6 at its top to move to the area below the corresponding test needle. The controller 1 is turned on to test the performance of the power battery. The slide rod 11 at the bottom of the placement platform 9 slides in the first slide groove 401, providing stable support for the movement of the placement platform 9 and the power battery body 6.
