Beneficial effects

[0019] Compared with the prior art, the present invention provides a thrust testing device for a battery cap, which has the following advantages:

[0020] 1. The thrust testing device for the battery cap, by rotating the handle, can drive the bidirectional lead screw to rotate at the bottom of the base cavity, so that two movable blocks can be threadedly connected to the bidirectional lead screw. At this time, the two movable blocks can drive the two reinforcing components to move to the opposite side, thus clamping and fixing the bottom of the battery cap placed in the mounting slot cavity. During subsequent thrust testing, it can prevent the cap from falling off, effectively ensuring the stability of the bottom, thereby ensuring the efficiency of the test and the accuracy of the results.

[0021] 2. The thrust testing device for the battery cap, through the set insertion slot, allows the second slider to be placed in the inner cavity of the insertion slot, thus facilitating the entry of the second slider into the inner cavity of the slide groove. At this time, by moving the first slider, the pressure sensor is driven to contact the top of the battery cap, and the lateral shear force can be tested. With the help of the set roller, when the second slider moves, it will drive the roller to move on the inner wall of the slide groove, thereby reducing friction and making the movement of the first slider smoother. Through this testing device, the battery caps of good quality can be prevented from the phenomenon of unstable values ​​due to power failure during subsequent use, thereby reducing the scrap rate and effectively reducing the cost of use and production. At the same time, it can also control the scoring allowance of the stamped battery caps, which can be used as a basis for production judgment.

[0022] 3. The thrust testing device for the battery cap, by activating the servo motor, allows the lead screw to rotate within the movable slot, enabling the bottom of the baffle to connect threadedly with the lead screw and move within the movable slot. When the baffle moves forward, it drives the first slider to slide forward, thus allowing the thrust of the battery cap to be tested using the first slider and pressure sensor. This mechanism is relatively simple and does not require manual movement of the first slider, thereby improving testing efficiency.

[0023] 4. The thrust testing device for the battery cap is compatible with various sizes of battery caps for installation, which facilitates thrust testing. The device is simple to operate and has a fast testing efficiency, which can effectively improve the overall production speed.

[0024] 5. The battery cover thrust testing device, through the set detection component, can test the thrust of the battery cover by touching the switch. When it comes into contact with the detection component, an alarm will be triggered by a buzzer, which can be used to determine that it is a defective product. By rotating the set handle, the threaded rod can be rotated, which can drive the loading component to move back and forth. This allows the position of the touch switch to be adjusted for different types of battery covers. The detachable L-shaped mounting block facilitates the disassembly and maintenance of the detection component. Attached Figure Description

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figure 1-3As shown, a thrust testing device for a battery cap includes a base 1. A test groove 2 is formed in the center of the top of the base 1. A mounting groove 5 is formed in the center of the bottom of the inner cavity of the test groove 2. Reinforcing components 6 are symmetrically and movably connected to the front and back of the inner cavity of the mounting groove 5. Arc-shaped grooves are symmetrically formed in the center of the opposite side of the two reinforcing components 6. Movable blocks 7 are symmetrically and fixedly connected to the center of the bottom of the two reinforcing components 6. A slot is formed in the center of the bottom of the inner cavity of the mounting groove 5. The movable blocks 7 are movably connected to the inner cavity of the slot. A bidirectional lead screw 8 is rotatably connected to the inner cavity of the slot. The two movable blocks 7 are symmetrically threaded to the two ends of the outer wall of the bidirectional lead screw 8. A rotating handle 9 is fixedly connected to the front of the lead screw 8. The rotating handle 9 is rotatably connected to the bottom of the front of the base 1. By rotating the rotating handle 9, the bidirectional lead screw 8 can be rotated at the bottom of the inner cavity of the base 1, so that the two movable blocks 7 can be threadedly connected to the bidirectional lead screw 8. At this time, the two movable blocks 7 can drive the two reinforcing components 6 to move to the opposite side. This can clamp and fix the bottom of the battery cap placed in the inner cavity of the mounting slot 5. During subsequent inference testing, it can prevent the cap from falling off and effectively ensure the stability of the bottom, thereby ensuring the efficiency of the test and the accuracy of the results.

[0034] like Figure 1 , 2As shown in Figure 4, a force testing device for a battery cap is provided. A first slider 10 is movably connected to the back of the inner cavity of the test groove 2. Second sliders 12 are symmetrically fixedly connected to the bottom of the front sides of the first slider 10 on both sides. Rollers 13 are symmetrically rotatably connected to opposite sides of the inner cavities of the two second sliders 12. A pressure sensor 11 is fixedly connected to the center of the front of the first slider 10. Insertion slots 3 are symmetrically opened on the back of the top left and right sides of the base 1. Sliding grooves 4 are symmetrically opened on the bottom of the left and right sides of the inner cavity of the test groove 2. The insertion slots 3 communicate with the inner cavities of the sliding grooves 4. The dimensions of the second sliders 12, insertion slots 3, and sliding grooves 4 are matched. The second sliders 12 are movably connected to the inner cavities of the sliding grooves 4. There are four rollers 13. Each second slider 12 has a hollow structure with opposite sides, front, and back sides communicating with the outside. Two rollers 13 form a group, and each group of rollers 13 is symmetrically rotatably connected to opposite sides of the inner cavities of the two second sliders 12. On the front and back sides, the second slider 12 can be placed in the inner cavity of the insertion slot 3 through the provided insertion slot 3, so that the second slider 12 can enter the inner cavity of the slide groove 4. At this time, by moving the first slider 10, the pressure sensor 11 is driven to contact the top of the battery cap, and the lateral shear force can be tested. With the help of the provided roller 13, when the second slider 12 moves, it will drive the roller 13 to move on the inner wall of the slide groove 4, which can reduce friction and make the movement of the first slider 10 smoother. Through this testing device, the battery cap of good quality can be prevented from the phenomenon of unstable value due to power failure during subsequent use, thereby reducing the scrap rate and effectively reducing the cost of use and production. At the same time, it can also control the scoring allowance of the stamped battery cap, which can be used as a basis for production judgment.

[0035] like Figure 1 , 5As shown, a thrust testing device for a battery cap includes a drive seat 14 fixedly connected to the center of the bottom back of a base 1. A baffle 15 is movably connected to the back top of the drive seat 14. The front of the baffle 15 is attached to the back of a first slider 10. A movable groove 17 is formed in the center of the top of the drive seat 14. A lead screw 18 is rotatably connected to the center of the inner cavity of the first slider 10. A servo motor 16 is fixedly connected to the front of the lead screw 18 via a rotating shaft. The back of the servo motor 16 is fixedly connected to the top of the front of the drive seat 14. A connecting block is fixedly connected to the center of the bottom of the baffle 15. The connecting block is movably connected to the inner cavity of the movable groove 17 and threaded to the outer wall of the lead screw 18. The device is activated by starting the servo motor 16. 6. The lead screw 18 can rotate within the inner cavity of the movable groove 17, allowing the bottom of the baffle 15 to be threadedly connected to the lead screw 18 and move within the inner cavity of the movable groove 17. When the baffle 15 moves forward, it drives the first slider 10 to slide forward. This allows the first slider 10 and the pressure sensor 11 to test the thrust of the battery cap. This mechanism is relatively simple and does not require manual movement of the first slider 10, thus improving testing efficiency. This device can be adapted to various sizes of battery caps for installation, facilitating thrust testing. The overall operation is simple, the testing efficiency is rapid, and it can effectively improve the overall production speed.

[0036] like Figure 1 , 6As shown, a thrust testing device for a battery cap includes an adjusting post 19 fixedly connected to the front of the inner cavity of the test slot 2. A loading assembly 20 is movably connected to the top of the adjusting post 19. A detection assembly 25 is installed on the back of the inner cavity of the loading assembly 20. A buzzer 24 is fixedly connected to the front of the top of the loading assembly 20. An adapter groove 21 is formed in the center of the top of the adjusting post 19. A threaded groove 22 is formed at the bottom of the front of the adjusting post 19. Fixed posts 30 are symmetrically fixedly connected to the front and back of the bottom of the loading assembly 20. A threaded rod 31 is rotatably connected to the center of one side of each of the two fixed posts 30. A handle 32 is fixedly connected to the front of the threaded rod 31 and rotatably connected to the center of the front of the fixed post 30. The loading assembly 20 is movably connected to the inner cavity of the adapter groove 21. The threaded rod 31 is threadedly connected to the inner cavity of the threaded groove 22. A slot is formed on the back of the loading assembly 20, and the detection assembly 25 is disposed in the inner cavity of the slot. The left side of the inner cavity of the slot... L-shaped mounting blocks 28 are symmetrically connected to the right sides. Bolts 29 are symmetrically threaded to the top of the two L-shaped mounting blocks 28. The bottom of the bolts 29 is threaded to the top of the detection component 25. A touch switch 26 is fixedly connected to the left side of the back of the detection component 25. A controller 27 is fixedly connected to the right side of the back of the detection component 25. A scale bar 2 is fixedly connected to the right side of the loading component 20. Through the detection component 25, the push force of the battery cap can be tested by the touch switch 26. When it contacts the detection component 25, an alarm will be triggered by the buzzer 24, which can be used to determine that it is a defective product. By rotating the handle 32, the threaded rod 31 can be rotated, which can drive the loading component 20 to move back and forth. This allows the position of the touch switch 26 to be adjusted for different types of battery caps. The detachable L-shaped mounting blocks 28 facilitate the disassembly and maintenance of the detection component 25.

[0037] It should be noted that this invention is a thrust testing device for a battery cap. In use, the bottom of the battery cap to be tested is placed in the inner cavity of the mounting groove 5, positioned on opposite sides of the two reinforcing components 6. Rotating the handle 9 causes the bidirectional lead screw 8 to rotate at the bottom of the base 1's inner cavity, allowing the two movable blocks 7 to be threadedly connected. This moves the two reinforcing components 6 to opposite sides until the front and back of the battery cap are clamped. The second sliders 12 on both sides of the first slider 10 are aligned with the insertion slots 3 and inserted until they enter the inner cavity of the slide groove 4. The servo motor 16 is activated, causing the lead screw 18 to rotate within the inner cavity of the movable groove 17, allowing the bottom of the baffle 15 to be threadedly connected to the lead screw 18. This moves the baffle 15 forward, allowing it to move the first slider 10 forward. When the first slider 10 moves, the second sliders 12 on both sides will drive the rollers 13 to move in the inner cavity of the two slide grooves 4. At the same time, the pressure sensor 11 will contact the battery cap, so that the thrust can be tested. The battery cap can also be tested according to the touch switch 26. The position of the detection component 25 is adjusted according to the type of battery cap. Rotating the handle 32 drives the threaded rod 31 to rotate, so that it can be threadedly connected to the inner cavity of the adjusting post 19 through the threaded groove 22. This drives the loading component 20 to move back and forth. At this time, the distance moved by the loading component 20 can be observed according to the scale bar 23. After moving to the appropriate position, the normal battery cap thrust test can be carried out. When the battery cap contacts the touch switch 26, the buzzer 24 will sound an alarm, which indicates that it is a defective product.
