[0018] Embodiment: As Figures 1-4 shown, the present utility model provides a helium leak detection and sealing tooling for new energy battery packs, including a workbench 1. One side of the top end of the workbench 1 is fixedly connected with a bracket 8. The top end of the bracket 8 is fixedly connected with a first cylinder 9, and the output end of the first cylinder 9 penetrates through the top end of the bracket 8 and is fixedly connected with a mounting plate 5. The bottom end of the mounting plate 5 is fixedly connected with a detector body 6. A moving mechanism 3 is arranged on one side inner wall of the workbench 1. The top end of the moving mechanism 3 is fixedly connected with a placement seat 7 for cooperating with the detector body 6. One end and the interior of the placement seat 7 are jointly provided with a positioning mechanism 2. First, place the battery pack to be detected in the placement seat 7 and position it through the positioning mechanism 2. Then, move the battery pack to a convenient position for detection through the moving mechanism 3. Then, start the first cylinder 9. The output end of the first cylinder 9 drives the detector body 6 to move downward through the mounting plate 5, so that the detector body 6 moves to a convenient position for detection. Then, start the detector body 6 to quickly detect the sealing performance of the battery pack.

[0019] The positioning mechanism 2 includes a protective housing 25. One end of the protective housing 25 is fixedly connected to one end of the placement seat 7. One side inner wall of the protective housing 25 is fixedly connected with a support plate 27. The top of the support plate 27 is fixedly connected with a second cylinder 26. The output end of the second cylinder 26 is fixedly connected with a connecting plate 201. One end of the connecting plate 201 is fixedly connected with a rack 29. The outer surface of the rack 29 is meshed with a gear 28. The inner wall of the gear 28 is fixedly connected with a double-headed screw rod 21. The two ends of the double-headed screw rod 21 are respectively rotatably connected to the two side inner walls of the protective housing 25. The outer surface of the double-headed screw rod 21 is threadedly sleeved with a moving rod 22. Limiting grooves 23 for cooperating with the two moving rods 22 are respectively formed on both sides of one end of the placement seat 7. One ends of the two moving rods 22 respectively penetrate through the two limiting grooves 23 and are fixedly connected with positioning plates 24. When the second cylinder 26 is started, the output end of the second cylinder 26 drives the rack 29 to move in the vertical direction through the connecting plate 201. The movement of the rack 29 cooperates with the gear 28 to make the double-headed screw rod 21 rotate. The rotation of the double-headed screw rod 21 drives the two moving rods 22 to move simultaneously. At the same time, the limiting grooves 23 play a role in facilitating the limiting of the moving positions of the moving rods 22. When the two moving rods 22 move and drive the two positioning plates 24 to move towards the opposite sides, the battery pack is positioned, preventing the battery pack from moving during detection and improving the accuracy of the detection result of the helium leak detection sealing tooling.

The worm gear 39 is fixedly sleeved on the outer surface of the round rod 38. A swing rod 301 is fixedly sleeved on the outer surface of the round rod 38. One end of the swing rod 301 is hinged with a clamping block 303 through a rotating shaft. Guide grooves 302 are respectively formed on both sides of the top of the workbench 1. A connecting seat 31 is slidably connected to the inner walls of the two guide grooves 302. The top of the connecting seat 31 is fixedly connected to the bottom end of the placement seat 7. One side of the bottom end of the connecting seat 31 is fixedly connected with a connecting rod 33. The middle of the bottom end of the connecting rod 33 is fixedly connected with a clamping groove 34 for cooperating with the clamping block 303. When the motor 36 is started, the output end of the motor 36 drives the worm 37 to transmit power. The transmission of the worm 37 drives the worm gear 39 to rotate. The rotation of the worm gear 39 drives the round rod 38 to rotate. The rotation of the round rod 38 drives the swing rod 301 to rotate. The rotation of the swing rod 301 drives the clamping block 303 to move. The movement of the clamping block 303 cooperates with the clamping groove 34 to make the clamping groove 34 drive the connecting rod 33 to move in the horizontal direction. The movement of the connecting rod 33 drives the placement seat 7 connected to the connecting seat 31 to move in the horizontal direction, so that the battery pack in the placement seat 7 moves to a suitable detection position, thereby improving the convenience of using the helium leak detection sealing tooling.

[0021] One end of each of the two moving rods 22 facing away from the positioning plate 24 is slidably connected to the inner wall of one side of the protective housing 25, which facilitates the guiding of the moving rod 22 when the protective housing 25 moves.

[0022] The two moving rods 22 are respectively threadedly sleeved at different thread directions provided on the outer surface of the double-headed screw rod 21, and both ends of the two moving rods 22 are slidably connected to the inner walls of both sides of the two limiting grooves 23, which facilitates the rotation of the double-headed screw rod 21 to drive the two moving rods 22 to move towards the opposite or back-to-back surfaces. At the same time, the limiting grooves 23 facilitate the limiting of the moving position of the moving rods 22.

[0023] The connecting seat 31 is in a "U" shape, and the lower inner wall of the connecting seat 31 is slidably connected to the upper inner wall of the workbench 1, which facilitates the guiding of the connecting seat 31 when it moves.

[0024] Both ends of the clamping block 303 are slidably connected to the inner walls of both sides of the clamping groove 34, which facilitates the cooperation of the clamping groove 34 with the clamping block 303, so that when the clamping block 303 moves in a circular trajectory, the clamping groove 34 moves in the horizontal direction.

[0025] The upper inner wall of the workbench 1 is fixedly connected with a guide rod 32 for cooperating with the connecting rod 33, and the connecting rod 33 is slidably sleeved on the outer surface of the guide rod 32.

[0026] Working principle: First, place the new energy battery pack to be detected in the placement seat 7 on the workbench 1, and then through the positioning mechanism 2, start the second cylinder 26. The output end of the second cylinder 26 drives the rack 29 to move in the vertical direction through the connecting plate 201. The movement of the rack 29 cooperates with the gear 28 to make the double-headed screw rod 21 rotate, and the rotation of the double-headed screw rod 21 drives the two moving rods 22 to move simultaneously;

[0027] At the same time, the limiting groove 23 facilitates the limiting of the moving position of the moving rod 22. When the two moving rods 22 move and drive the two positioning plates 24 to move towards the opposite surfaces, the battery pack is positioned;

[0028] Then through the moving mechanism 3, start the motor 36. The output end of the motor 36 drives the worm 37 to drive. The worm 37 drives the worm wheel 39 to rotate. The rotation of the worm wheel 39 drives the round rod 38 to rotate. The rotation of the round rod 38 drives the swing rod 301 to rotate. The rotation of the swing rod 301 drives the clamping block 303 to move in a circular trajectory;

[0029] The movement of the clamping block 303 in cooperation with the clamping groove 34 causes the clamping groove 34 to drive the connecting rod 33 to move in the horizontal direction. The guide rod 32 serves to facilitate the guiding of the connecting rod 33 during movement. The movement of the connecting rod 33 drives the placement seat 7 connected to the connecting seat 31 to move in the horizontal direction. At the same time, the guiding groove 302 serves to facilitate the guiding of the connecting seat 31 during movement, enabling the battery pack in the placement seat 7 to move to a suitable detection position;

[0030] Then, the first cylinder 9 is activated. The output end of the first cylinder 9 drives the detector body 6 to move downward through the mounting plate 5, causing the detector body 6 to move to a position convenient for detection. Then, the detector body 6 is activated to quickly detect the sealing performance of the battery pack.
