Detailed Implementation

[0013] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0014] Example: This example provides a motorcycle battery ultrasonic cover sheet strength testing fixture. After the battery with the cover sheet is clamped at the bottom, a vacuum generator creates negative pressure, and a suction cup holds the cover sheet. Rotating the handwheel generates tension, and the tension count is displayed. When the required value is reached, the battery is tested. The base plate 1 serves as the basic component of the device, used for component installation and battery placement. Left push plate 2 and right push plate 3 are installed on the left and right sides of the base plate to fix the battery position. First contact plate 4.1 and second contact plate 4.2 are installed on the push plates on both sides to contact the battery. The battery is then clamped by quick clamp 11 to prevent it from being pulled up during testing. Two second guide rods 7.2 are installed on the base plate 1 through flanges. Fixing plate 6.3 and fixing plate 6.2 are installed on the guide rods 7.2. Fixing plate 6.2 is installed on the top of the guide rod 7.2, and fixing plate 6.3 is installed in the middle of the guide rod. Threaded guide rod 7.1 passes through flange 5.2. A handwheel 17 is installed at the top, passing through the fixed plate 6.3 (connected via the second flange sleeve 5.2) and 6.2 (connected via the deep groove ball bearing 18). A small guide rod is installed in the middle of the fixed plate 6.3 to hang the tension gauge 19. The suction cup assembly 8 is hung below the tension gauge. A flat vacuum suction cup 14 is installed below the suction cup assembly 8. The vacuum generator 12 is installed on the right side of the fixed plate 6.3. A manual valve 13 is installed on the lower right side of the base plate 1. The manual valve 13 is equipped with a built-in manual valve silencer 16. The vacuum generator 12 is connected to the air inlet pipe and the air outlet pipe. The air outlet pipe is connected to the air pipe connector 15, and the air pipe is then connected to the suction cup assembly 8. When working, first place the battery between contact plates 4.1 and 4.2, clamp the quick clamp 11, turn down the handwheel 17, press the suction cup 14 onto the battery faceplate, open the manual valve 13, use vacuum pressure to suction the battery, turn the handwheel 17, the suction cup assembly 8 rises, during the rise the tension gauge 19 shows the tension, reaching a certain value indicates that it is qualified.

[0015] Please refer to Figure 1 This embodiment provides a fixture for testing the tensile strength of battery faceplates.

[0016] Before testing, ensure all components are installed and the air pipe is connected. Use the left push plate 2 and right push plate 3 to quickly clamp the battery 11. Adjust the handwheel 17 to lower the height of the suction cup assembly 8 until the suction cup 14 is lower than the battery height. Open the manual valve 13 and let the suction cup 14 hold the battery faceplate. Turn the handwheel 17 to raise the fixing plate 6.3, which will drive the tension gauge 19 to generate tension. Once a certain value is reached and the test is qualified, stop turning the handwheel 17. The battery test is over.
