[0002] During the production and processing of automotive flooring, it is usually necessary to use inspection tools to test it to ensure that the automotive flooring meets the requirements of the actual device, including but not limited to testing the shape and aperture of the automotive flooring.

[0003] Chinese utility model patent CN222837469U discloses a positioning structure for an automotive inspection tool, including a worktable. A movable box is mounted inside the worktable, and a movable motor is fixedly connected to the front of the movable box. A threaded rod, rotatably connected to the inner wall of the movable box, is fixedly connected to the end of the output shaft of the movable motor. Through an electric push rod, gears, and racks, a clamping motor drives the gears to rotate, which in turn drives two sets of racks to move in opposite directions. These racks then drive the right and left movable blocks to move in opposite directions, thereby moving the right clamping block and the left... The clamping block moves, and the drive plate and auxiliary plate move in opposite directions, so that the drive plate and auxiliary plate contact the surface of the car part respectively. With the cooperation of the drive plate and auxiliary plate, the car part is clamped and positioned. Then, the car part is inspected using a fixture. However, since both the drive plate and auxiliary plate are disc-shaped, the stability of the car floor is low after clamping it.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a clamping and positioning structure for an automotive floor inspection fixture, comprising a base 1 and a lifting mechanism 9 on its top. A column 2 is fixedly installed at the center of the top of the base 1. The lifting mechanism 9 includes a second hydraulic cylinder 10 and a lifting plate 22. A fixing plate 23 is fixedly installed at the middle of the top of the lifting plate 22. A first lifting plate 24 and a second lifting plate 25 are respectively installed on both sides of the fixing plate 23 via lifting hydraulic cylinders 26. An automotive floor 11 is placed on top of the fixing plate 23, the first lifting plate 24, and the second lifting plate 25. A first adjusting plate 5 and a second adjusting plate 6 are slidably installed inside both ends of the base 1 via base grooves 4. A first clamping mechanism is respectively installed inside the top of the first adjusting plate 5 and the second adjusting plate 6. The first clamping mechanism 7 and the second clamping mechanism 8 each include an L-shaped fixing frame 12, a rotating column 14, a servo motor 13, a fixed clamping plate 15, and an adjusting clamping plate 16. The servo motor 13 is mounted on the outer wall of the top of the first adjusting plate 5 and the second adjusting plate 6 through the L-shaped fixing frame 12. By adjusting the adjusting clamping plate 16, the distance between the adjusting clamping plate 16 and the fixed clamping plate 15 is reduced, which facilitates clamping and fixing both ends of the car floor 11, improves the stability of the car floor 11, prevents the car floor 11 from bending and affecting the test results, and improves the practicality of the device. By adjusting the lifting of the first lifting plate 24 and the second lifting plate 25, the stability of the car floor 11 can be improved, and the car floor 11 can also be supported.

[0024] In this embodiment, the second hydraulic cylinder 10 is fixedly installed inside the top of the column 2. The lifting plate 22 is fixedly installed at the top of the output rod of the second hydraulic cylinder 10. First hydraulic cylinders 3 are symmetrically fixedly installed on both sides of the bottom of the column 2 corresponding to the top of the base 1. Fixing rods 19 are symmetrically fixedly installed on both sides of the column 2 corresponding to the top of the first hydraulic cylinders 3. A telescopic rod 20 is slidably installed inside the fixing rod 19. One end of the telescopic rod 20 is fixedly connected to the first adjusting plate 5 and the second adjusting plate 6 respectively. The output rod of the first hydraulic cylinder 3 is connected to the bottom side of the first adjusting plate 5 and the second adjusting plate 6. The base is fixedly connected to the wall. The base groove 4 is symmetrically opened inside both ends of the base 1. The bottom ends of the first adjusting plate 5 and the second adjusting plate 6 are limited and slidably installed inside the base groove 4. The first hydraulic cylinder 3 can adjust the first adjusting plate 5 and the second adjusting plate 6 laterally. The base groove 4, the fixed rod 19 and the telescopic rod 20 can limit the first adjusting plate 5 and the second adjusting plate 6, which can improve the stability of the first adjusting plate 5 and the second adjusting plate 6. At the same time, the stability of the car floor 11 is improved by the first clamping mechanism 7 and the second clamping mechanism 8, which facilitates the subsequent inspection of the car floor 11.

[0025] In this embodiment, the lifting hydraulic cylinders 26 are symmetrically fixed at the bottom of both ends of the lifting plate 22. The first lifting plate 24 and the second lifting plate 25 are respectively fixed at the top of the output rods of the lifting hydraulic cylinders 26 on both sides. Limiting rods 27 are fixedly provided at the bottom of both ends of the first lifting plate 24 and the second lifting plate 25. The bottom end of the limiting rod 27 is slidably disposed inside the lifting plate 22. The limiting rod 27 can conveniently limit the first lifting plate 24 and the second lifting plate 25, which can improve the stability of the first lifting plate 24 and the second lifting plate 25 when the lifting hydraulic cylinder 26 lifts and lowers them. By adjusting the lifting and lowering of the first lifting plate 24 and the second lifting plate 25, the stability of the car floor 11 can be improved.

[0026] In this embodiment, the L-shaped fixing frame 12 is fixedly mounted on the outer wall of the top of the first adjusting plate 5 and the second adjusting plate 6. The servo motor 13 is fixedly mounted on the outer wall of one end of the L-shaped fixing frame 12. An encoder is mounted on the servo motor 13. The output shaft of the servo motor 13 is fixedly connected to the center position of one end of the rotating column 14. The rotating column 14 is rotatably mounted inside the top of the first adjusting plate 5 and the second adjusting plate 6. One end of the rotating column 14 is located inside the L-shaped fixing frame 12. A limiting groove 18 is formed inside the other end of the rotating column 14. One end of the adjusting clamp 16 is slidably mounted inside the limiting groove 18. The fixing clamp 15 is fixedly mounted on the top of the side wall of the other end of the rotating column 14. The fixing clamp 15 is located above the adjusting clamp 16. A third liquid is fixedly mounted at the bottom of one end of the rotating column 14. The pressure cylinder 17 has its output rod fixedly connected to the inner end of the adjusting clamp 16. A rubber pad 21 is fixedly provided on the opposite side of the fixed clamp 15 and the adjusting clamp 16. The two ends of the car floor 11 are located inside the fixed clamp 15 and the adjusting clamp 16. The adjusting clamp 16 can be vertically adjusted by the third hydraulic cylinder 17 to reduce the distance between the adjusting clamp 16 and the fixed clamp 15, thus facilitating the clamping and fixing of the two ends of the car floor 11. The encoder can control the servo motor 13 so that the two servo motors 13 can rotate in the same direction at the same speed, facilitating the flipping detection of the car floor 11. By individually rotating and adjusting the first clamping mechanism 7 or the second clamping mechanism 8, the two ends of the car floor 11 can be clamped and fixed separately when they are not in the same horizontal plane, making the operation simple and convenient.

[0027] When using this automotive floor fixture clamping and positioning structure, based on the bottom shape of the automotive floor 11, the lifting hydraulic cylinder 26 and its associated circuitry are used to adjust the lifting of either the first lifting plate 24 or the second lifting plate 25, causing the first and second lifting plates 24 and 25 to be staggered with the fixed plate 23. The automotive floor 11 is then placed on top of the staggered first lifting plate 24, second lifting plate 25, and fixed plate 23. Simultaneously, the second hydraulic cylinder 10 and its associated circuitry are used to raise the lifting mechanisms 9, including the lifting plate 22, fixed plate 23, first lifting plate 24, and second lifting plate 25. The lifting mechanism 9 moves the car floor 11 upwards between the first clamping mechanism 7 and the second clamping mechanism 8. The first hydraulic cylinder 3 and its associated circuit pull the first adjusting plate 5 and the second adjusting plate 6 relative to each other. The bottom ends of the first adjusting plate 5 and the second adjusting plate 6 slide within the base groove 4, simultaneously causing the telescopic rod 20 to slide within the fixed rod 19. The base groove 4, the telescopic rod 20, and the fixed rod 19 improve the stability of the first adjusting plate 5 and the second adjusting plate 6. The first adjusting plate 5 and the second adjusting plate 6 respectively drive the first clamping mechanism 7 and the second clamping mechanism 8 towards the car floor. The two ends of the car floor 11 are brought close together, and the fixing clamp 15 and adjusting clamp 16 are moved to the top and bottom of the two ends of the car floor 11 respectively. The adjusting clamp 16 is adjusted by the third hydraulic cylinder 17 and its matching circuit, so that one end of the adjusting clamp 16 slides inside the limiting slide groove 18 and squeezes the bottom of the car floor 11. This facilitates the clamping and fixing of the two ends of the car floor 11 by the fixing clamp 15 and adjusting clamp 16, avoiding direct compression that could cause the car floor 11 to bend and affect the detection of the car floor 11. When the two ends of the car floor 11 are not in the same water... When in the plane, the servo motor 13 on one side drives the rotating column 14 to rotate, thereby exchanging the positions of the fixed clamping plate 15 and the adjusting clamping plate 16. At this time, the adjusting clamping plate 16 is above the fixed clamping plate 15, which facilitates clamping and fixing the upper end of the car floor 11. The encoder controls the two servo motors 13 to rotate and adjust the rotating column 14 at the same speed and direction, which facilitates the rotation and adjustment of the car floor 11 through the rotating column 14, the fixed clamping plate 15, and the adjusting clamping plate 16, making it convenient to perform flipping detection of the car floor 11 and ensuring the accuracy of the detection of the car floor 11.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
