[0029] During operation, the battery is clamped by the clamping arc plate, but the clamping arc plate is supported by a spring. When the battery is clamped and an impact test is performed, the impacted battery will move, and the spring will be squeezed during the movement. The spring will rebound when being squeezed, and the battery may be ejected from the placement tray under the rebound, thereby damaging the battery. In order to prevent such an incident from happening, first, the battery body 6 is placed on the clamping box 31 in the clamping assembly 3, and then the clamping screw 37 is driven to rotate. When rotating, the threaded clamping block 39 will be driven to move, and the clamping screw 3 7 is provided with four groups.

[0031] During operation, after the battery body 6 is installed, the test ball is placed from the test bucket 52 into the test tube 51. The test tube 51 is used for limiting to prevent the test ball from deviating during the falling process and hitting other parts. During specific use, the telescopic column 41 drives the test tube 51 to move to the top of the clamping box 31, and then the test ball is placed from the test bucket 52 into the test tube 51. A notch 53 is opened on the side wall of the test tube 51, and a baffle 54 is set at the notch 53. By setting the baffle 54, it can be controlled whether the test ball falls from a high place or a low place, so as to obtain different test results.

[0032] like Figure 1 and Figure 3As shown, a moving groove 11 is provided on the surface of the detection base 1; a moving screw 14 is rotatably connected in the moving groove 11; a moving block 13 is threadedly connected on the moving screw 14; the bottom of the clamping box 31 is fixedly connected to the moving block 13; a limiting block 313 is fixedly connected to the bottom of the clamping box 31; limiting grooves 12 are provided on the detection base 1 on both sides of the moving groove 11; one end of the limiting block 313 away from the clamping box 31 is slidably connected in the limiting groove 12; a moving motor 15 is fixedly connected to the side wall of the detection base 1; the moving screw 14 is driven to rotate by the moving motor 15;

[0033] During operation, a moving unit is provided on the detection base 1, which can drive the clamping box 31 to move. When different parts of the battery body 6 need to be tested, the moving screw 14 can be driven to rotate. When rotating, the moving screw 14 drives the moving block 13 to move, thereby driving the clamping box 31 to move to different positions, and then cooperate with the test tube 51 above to test it. When moving, in order to prevent the clamping box 31 from shifting, limit grooves 12 and limit blocks 313 are provided at both ends of the clamping box 31. The limit blocks 313 are slidably connected in the limit grooves 12, which can limit the clamping box 31.

[0035] During operation, when the battery body 6 is clamped, the driving motor 32 drives the driving shaft 33 to rotate, and the crown gear 34 is driven to rotate during rotation, thereby driving the transmission gear 38 to rotate.

[0037] During operation, the telescopic plate 315 is slidably connected in the clamping groove 314, and the other end of the telescopic plate 315 is fixedly connected to the side wall of the clamping block 39. When the clamping block 39 moves, the telescopic plate 315 is driven to retract, so that the clamping groove 314 is always in a closed state to prevent dust from entering the clamping box 31 and causing transmission failure.

[0038] like Figure 1 and Figure 2 As shown, the surface of the clamping box 31 is fixedly connected with an anti-skid pad 312; the anti-skid pad 312 is made of rubber; the side wall of the clamping box 31 is fixedly connected with a protective plate 311; the protective plate 311 is provided in multiple groups;

[0041] During operation, the support legs 2 can support the detection base 1 , and the rubber pads 21 can prevent the support legs 2 from slipping.

[0042] The working principle of the utility model is as follows: the battery is clamped by a clamping arc plate, but the clamping arc plate is supported by a spring. When the battery is clamped and an impact test is performed, the impacted battery will move, and the spring will be squeezed during the movement. The spring will rebound when being squeezed, and the battery may be ejected from the placement tray under the rebound, thereby damaging the battery. In order to prevent such an incident from happening, first, the battery body 6 is placed on the clamping box 31 in the clamping assembly 3, and then the clamping screw 37 is driven to rotate, which will drive the threaded clamping block 39 to move during the rotation, and the clamping Four groups of screw rods 37 are arranged. When the four groups of clamping screw rods 37 rotate at the same time, the four groups of clamping blocks 39 will move toward the battery body 6 at the same time, so that the battery body 6 can be clamped by the clamping plate 391, and the clamping pad 392 is fixed to the clamping plate 391. The clamping pad 392 is made of rubber. The rubber clamping pad 392 can play a protective role when clamping the battery body 6, and prevent the battery body 6 from being damaged by the clamping of the clamping plate 391. Through the arrangement of the clamping screw rods 37 and the clamping plate 391, the battery body 6 can be prevented from moving during testing, and the battery body 6 can be prevented from flying out and causing damage.

[0043] Among them, different parts of the battery body 6 are detected through components such as a moving unit. A moving unit is set on the detection base 1, which can drive the clamping box 31 to move. When different parts of the battery body 6 need to be tested, the moving screw 14 can be driven to rotate. When rotating, the moving screw 14 drives the moving block 13 to move, thereby driving the clamping box 31 to move to different positions, and then cooperate with the test tube 51 above to test it. When moving, in order to prevent the clamping box 31 from shifting, a limit groove 12 and a limit block 313 are set at both ends of the clamping box 31. The limit block 313 is slidably connected in the limit groove 12, which can have a limiting effect on the clamping box 31.

[0044] 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.
