Description

Technical Field

[0001] This utility model relates to the field of automotive cover plate testing equipment, and in particular to an automotive cover plate pressure resistance testing device. Background Technology

[0002] As an important component of automotive body panels, car covers not only play a decisive role in the aesthetic appearance of vehicles, but also undertake practical functions such as protecting the internal structure, dustproofing, waterproofing, and sound insulation. To ensure that the performance, safety, and quality of car covers meet design requirements and comply with stringent automotive industry standards, car covers are sampled during production and subjected to stamping tests using a pressure testing device.

[0003] Existing stamping equipment basically consists of a testing chamber, hydraulic cylinders, a stamping plate, multiple clamping frames, and multiple telescopic cylinders. The hydraulic cylinders are fixedly installed inside the testing chamber. When the operator places the car cover to be tested into the testing chamber, the hydraulic cylinders drive the stamping plate to extend, thus performing a stamping test on the car cover. When the car cover is placed inside the transfer chamber, the multiple telescopic cylinders inside the testing chamber extend, causing the multiple telescopic cylinders to drive the multiple clamping frames to extend, thus clamping and limiting the car cover inside the testing chamber. This structure uses multiple telescopic cylinders to clamp and limit the car cover, which increases the cost of the equipment, increases the company's operating costs, and reduces the company's competitiveness in the market.

[0004] Therefore, it is necessary to provide a new automobile cover pressure testing device to solve the above-mentioned technical problems. Utility Model Content

[0027] In the specific implementation process, such as Figures 1-8As shown, a car cover pressure testing device includes a testing chamber 1. A stamping mechanism is fixedly installed at the top of the testing chamber 1. A power mechanism is fixedly installed inside the testing chamber. Two limiting mechanisms are fixedly installed at the top of the power mechanism. The limiting mechanisms include two fixed frames 2.

A connecting crank 8 is positioned between the two fixed blocks 7. A fixing post 9 is slidably mounted inside one of the fixed blocks 7. One end of the fixing post 9 passes through the connecting crank 8 and extends into the interior of the other fixed block 7. The outer surface of the fixing post 9... The inner surface of the fixed column 9 is rotatably connected to the inner surface of the connecting crank 8. The outer surface of the fixed column 9 is fixedly connected to the inner surface of the connecting crank 8. Two transmission blocks 10 are fixedly provided on the outer surface of the power assembly. The side of the connecting crank 8 away from the fixed column 9 extends into the two transmission blocks 10. Two transmission columns 11 are fixedly provided at both ends of the connecting crank 8. The ends of the two transmission columns 11 away from the connecting crank 8 extend into the two transmission blocks 10 respectively. The inner surfaces of the two transmission blocks 10 are rotatably connected to the outer surfaces of the two transmission columns 11 respectively. The clamping assembly includes two square frames 12. One side of the two square frames 12 is fixedly connected to one side of the inside of the detection chamber 1. A movable block 13 is provided between the two square frames 12. The two ends of the movable block 13 are fixedly connected to the inner surface of the detection chamber 1 respectively. Two sliders 14 are fixedly provided. The ends of the two sliders 14 away from the movable block 13 extend into the interior of the two square frames 12 respectively. The outer surfaces of the two sliders 14 are slidably connected to the inner surfaces of the two square frames 12 respectively. A square block 15 is fixedly provided on one side of the movable block 13. A clamping frame 16 is fixedly provided on the side of the square block 15 away from the movable block 13. Two limiting blocks 17 are fixedly provided at the bottom of the movable block 13. A support crank 18 is provided between the two limiting blocks 17. Two limiting posts 19 are fixedly provided at both ends of the support crank 18 respectively. The ends of the two limiting posts 19 away from the support crank 18 extend into the interior of the two limiting blocks 17 respectively. The outer surfaces of the two limiting posts 19 are rotatably connected to the inner surfaces of the two limiting blocks 17 respectively.

[0028] Two blocking blocks 20 are fixedly provided on one side of the outer surface of the power mechanism. Two blocking posts 21 are fixedly provided at both ends of the side of the support crank 18 away from the two limiting posts 19. The ends of the two blocking posts 21 away from the support crank 18 extend out of the interior of the two blocking blocks 20. The outer surfaces of the two blocking posts 21 are rotatably connected to the inner surfaces of the two blocking blocks 20. The power assembly includes a motor 22. The motor 22 is fixedly connected to the interior of the detection chamber 1. A threaded post 23 is fixedly provided at the top of the motor 22. The outer surface of the threaded post 23 is sleeved on the movable ring 24. The inner surface of the movable ring 24 is threadedly connected to the outer surface of the threaded post 23. The outer surface of the movable block 13 is fixedly connected to one side of the two transmission blocks 10 and one side of the two blocking blocks 20.

[0029] After the staff places the car cover into the testing chamber 1, they start the motor 22, which drives the threaded column 23 to rotate. The threaded column 23 then drives the movable ring 24 downwards. Simultaneously, the movable ring 24 drives the transmission block 10 downwards. The transmission block 10, through the transmission column 11, drives the connecting crank 8 downwards. The connecting crank 8, through the fixed column 9, drives the fixed block 7. Simultaneously, the fixed block 7 drives the connecting block 6 to extend, and the connecting block 6 also drives the limit frame 3 to extend. The moving ring 24 drives the blocking column 21 to move through the blocking block 20, which in turn drives the supporting crank 18 to move. The supporting crank 18 drives the limiting block 17 to move through the limiting column 19. The limiting block 17 drives the square block 15 to extend through the movable block 13, which in turn drives the clamping frame 16 to extend. By extending the clamping frame 16 and the limiting frame 3 simultaneously, the clamping and limiting of the car cover plate placed in the testing chamber 1 is completed. Then, the staff can start the stamping mechanism to perform a stamping test on the car cover plate.

[0030] After the stamping mechanism is tested, the motor 22 drives the movable ring 24 upward through the threaded column 23, which in turn drives the transmission block 10 upward. The transmission block 10 drives the connecting crank 8 upward through the transmission column 11. The connecting crank 8 drives the fixed block 7 through the fixed column 9, and the fixed block 7 drives the connecting block 6 to retract. The connecting block 6 also drives the limiting frame 3 to retract. At the same time, the movable ring 24 drives the blocking column 21 through the blocking block 20, which in turn drives the supporting crank 18. The supporting crank 18 drives the limiting block 17 through the limiting column 19, and the limiting block 17 drives the square block 15 to retract through the movable block 13. The square block 15 then drives the clamping frame 16 to retract. By retracting the clamping frame 16 and the limiting frame 3 simultaneously, the clamping and limiting of the car cover plate placed in the testing chamber 1 is released.

[0031] The guide block 5 limits the movement range of the movable ring 24 through the fixed frame 2 and the slider 14 through the square frame 12, preventing the movable ring 24 from disengaging from the connection with the threaded column 23. At the same time, the fixed frame 2 limits the guide block 5, so that the limiting frame 3 can only move in a straight line through the guide block 5. Meanwhile, the square frame 12 limits the slider 14, so that the clamping frame 16 can only move in a straight line through the slider 14.

[0032] The testing chamber 1 is fixedly provided with a partition plate 26. The partition plate 26 has four movable slots 25 for ensuring the normal movement of the two connecting cranks 8 and the two supporting cranks 18. The stamping mechanism includes a support frame 29. The bottom of the support frame 29 is fixedly connected to the top of the testing chamber 1. A hydraulic cylinder 27 is fixedly provided at the top of the support frame 29. A stamping plate 28 is provided inside the support frame 29. The protruding end of the hydraulic cylinder 27 extends through the support frame 29 and into the interior of the stamping plate 28. The outer surface of the protruding end of the hydraulic cylinder 27 is slidably connected to the inner surface of the support frame 29. The outer surface of the protruding end of the hydraulic cylinder 27 is fixedly connected to the inner surface of the stamping plate 28.

[0033] Once the limiting mechanism has completed clamping and limiting the car cover plate placed inside the testing chamber 1, the operator can activate the hydraulic cylinder 27 to extend it, causing the hydraulic cylinder 27 to drive the stamping plate 28 downwards. The stamping plate 28 then performs a stamping test on the car cover plate. Subsequently, the hydraulic cylinder 27 drives the stamping plate 28 to reset, and the operator can then operate the limiting mechanism to release the clamping and limiting of the car cover plate, allowing the car cover plate to be removed directly.
