Technical Field

[0001] This utility model relates to the field of automotive inspection tool technology, and in particular to a locking device for automotive inspection tools. Background Technology

[0002] Automotive inspection fixtures are specialized measuring tools used in the automotive manufacturing industry to accurately inspect the size, shape, position, and assembly relationship of automotive parts. Their core function is to ensure that parts meet design standards and to guarantee the assembly accuracy and quality consistency of the whole vehicle. They are indispensable quality control equipment in the automotive research and development and production process.

[0003] Existing locking devices for automotive inspection fixtures can only clamp and fix automotive parts from both sides. However, when the part is pressed during inspection, one end of it will tilt upwards, causing the part to tilt as a whole and thus causing the inspection position to shift, ultimately resulting in incorrect inspection data. Therefore, it is necessary to design a locking device for automotive inspection fixtures that can limit and fix the top of the part, thereby preventing the part from tilting upwards during inspection and causing the inspection position to shift. Utility Model Content

[0004] The purpose of this utility model is to provide a locking device for automotive inspection tools in order to solve the above problems. The device uses a height adjustment component to press and fix the automotive parts from the top, thereby preventing the parts from being lifted up during processing and causing the inspection position to shift.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A locking device for an automotive inspection tool includes a worktable. An electric actuator is mounted on the top of the worktable. One end of the electric actuator is fixedly connected to a horizontal push plate. A height adjustment assembly is mounted on the horizontal push plate. The height adjustment assembly includes a movable block, a pressure plate, a threaded rod, a worm gear, and a worm. The movable block is slidably connected to the inner wall of the horizontal push plate. The pressure plate is fixedly connected to the top of the movable block. The threaded rod is threadedly connected to the inner wall of the horizontal push plate. The worm gear is fixedly connected to the outer wall of the threaded rod. One side of the worm gear meshes with the worm. The worm extends from the inside of the horizontal push plate to the outside. A limit assembly is installed inside the horizontal push plate.

[0007] Preferably, the limiting assembly includes a rotating block, a limiting plate, and a limiting wheel. The outer wall of the worm gear is connected to the rotating block via a torsion spring shaft. A limiting plate is provided on one side of the rotating block. The limiting plate is fixedly connected to the outer wall of the worm gear. The limiting wheel is movably connected to the outer wall of the rotating block.

[0008] Preferably, a movable rod is fixedly connected to one side of the limiting wheel, and the movable rod is slidably connected to the inner wall of the push plate.

[0009] Preferably, a circular block is fixedly connected to one end of the movable rod, and the circular block is connected to the horizontal push plate by a spring.

[0010] Preferably, a knob is fixedly connected to one end of the worm gear located outside the push plate.

[0011] Preferably, a rubber pad is fixedly connected to one side of the push plate and the bottom of the pressure plate.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] In this application, after the car parts are placed on the worktable, the electric push rod will drive the cross push plate to press and fix the car parts on both sides.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] like Figure 1-6 As shown, a locking device for an automotive inspection tool includes a worktable 1. An electric push rod 2 is mounted on the top of the worktable 1. One end of the electric push rod 2 is fixedly connected to a horizontal push plate 3. A height adjustment assembly is mounted on the horizontal push plate 3. The height adjustment assembly includes a movable block 4, a pressure plate 5, a threaded rod 6, a worm gear 7, and a worm 8. The inner wall of the horizontal push plate 3 is slidably connected to the movable block 4 for moving the pressure plate 5. The top of the movable block 4 is fixedly connected to the pressure plate 5 for pressing and fixing the top of the automotive parts. The inner wall of the movable block 4 is threadedly connected to a threaded rod 6 for moving the movable block 4 through the thread. The threaded rod 6 is rotatably connected to the inner wall of the horizontal push plate 3. The outer wall of the threaded rod 6 is fixedly connected to a worm gear 7 for rotating the threaded rod 6. One side of the worm gear 7 meshes with a worm 8 for meshing with the worm gear 7. The worm 8 extends from the inside of the horizontal push plate 3 to the outside. A limit assembly is installed inside the horizontal push plate 3.

[0025] like Figure 6 As shown, the limiting assembly includes a rotating block 9, a limiting plate 10, and a limiting wheel 11. The outer wall of the worm gear 7 is connected to the rotating block 9 via a torsion spring shaft. A limiting plate 10 is provided on one side of the rotating block 9 and is fixedly connected to the outer wall of the worm gear 7. When the rotating block 9 rotates clockwise, it is limited by the limiting wheel 11 in conjunction with the limiting plate 10 and cannot rotate. When the rotating block 9 rotates counterclockwise, it will rotate after contacting the limiting wheel 11, thus preventing the rotating block 9 from being blocked by the limiting wheel 11. After rotating, the rotating block 9 will be reset via the torsion spring shaft. The outer wall of the rotating block 9 is movably connected to the limiting wheel 11, which allows the rotating block 9 to rotate only counterclockwise. A movable rod 12 is fixedly connected to one side of the limiting wheel 11 to drive the limiting wheel 11 to move. Figure 2As shown, the movable rod 12 is slidably connected to the inner wall of the horizontal push plate 3. One end of the movable rod 12 is fixedly connected to a circular block 13. The circular block 13 and the horizontal push plate 3 are connected to each other by a spring 14. The spring 14 can reset the limit wheel 11 after it has moved. The end of the worm gear 8 located outside the horizontal push plate 3 is fixedly connected to a knob 15. The knob 15 can facilitate the operator to rotate the worm gear 8. Rubber pads are fixedly connected to one side of the horizontal push plate 3 and the bottom of the pressure plate 5. The rubber pads can prevent the horizontal push plate 3 and the pressure plate 5 from directly contacting the car parts and causing damage to the car parts.

[0026] Working Principle: In this embodiment, the locking device for automotive inspection tools involves the operator first placing the automotive part on the workbench 1. Then, the operator activates the electric actuator 2, which drives the horizontal push plate 3 to press and fix the sides of the automotive part. Next, the operator rotates the knob 15, which drives the worm gear 8 to rotate counter-clockwise. At this time, the rotating block 9 on the worm gear 8 also rotates counter-clockwise. After contacting the limit wheel 11, the rotating block 9 rotates without affecting the rotation of the worm gear 8. This causes the worm gear 8 to mesh with the worm wheel 7, which in turn drives the threaded rod 6 to rotate. The threaded rod 6 then moves downwards via the threaded movable block 4, which in turn drives the pressure plate 5 downwards. The pressure plate 5 then presses against the worm gear from the top. The automotive parts are pressed and fixed to prevent them from warping during processing and causing the inspection position to shift. The limiting wheel 11 prevents the worm gear 8 from rotating clockwise via the rotating block 9. When the rotating block 9 rotates clockwise, it is limited by the limiting wheel 11 and the limiting plate 10. This prevents the worm gear 8 from rotating and causing the pressure plate 5 to move upwards due to vibration or accidental contact of the worktable 1 during inspection. After inspection, the operator simply presses the circular block 13, which, via the movable rod 12, moves the limiting wheel 11 away from the rotating block 9. The operator can then rotate the worm gear 8 clockwise using the knob 15, causing the pressure plate 5 to return to its upward position, thus releasing the limiting and fixing of the automotive parts.

[0027] In summary, when the car parts are placed on the workbench 1, the electric push rod 2 will drive the horizontal push plate 3 to press and fix the car parts on both sides. At the same time, the operator can rotate the worm gear 8 to engage the worm wheel 7. The worm wheel 7 will drive the threaded rod 6 to rotate. The threaded rod 6 will cause the movable block 4 to move the pressure plate 5 downward through the thread. The pressure plate 5 will press and fix the car parts from the top, preventing the parts from being lifted up during processing and causing the detection position to shift.
