[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0023] A flip-up automotive fixture locking device, see [link / reference] Figures 1 to 3 The system includes a support frame 1, a worktable 3, an adjustment groove 6, and a folding frame 14. Support plates 2 are fixedly connected to both sides of the top surface of the support frame 1. Support shafts 4 are fixedly connected to the center of both sides of the worktable 3, and the worktable 3 is rotatably connected to the support plates 2 via the support shafts 4. A turntable 5 is fixedly connected to the outer end of the support shaft 4 on one side of the worktable 3. A protrusion 501 is fixedly connected to the edge of the surface of the turntable 5. An adjustment groove 6 is fixedly connected to the surface of the support frame 1 directly below the protrusion 501. A threaded rod 7 is rotatably connected to the inner side of the adjustment groove 6. A threaded block 8 passes through the surface of the threaded rod 7 and is threaded with the threaded block 8. The threaded block 8 is connected to a vertical block 9, and small screws 10 are threaded through both the upper and lower ends of the side wall of the vertical block 9. One end of the small screw 10 is rotatably connected to the movable block 11 through a bearing. The support shaft 4 and the turntable 5 rotate to adjust the angle of the worktable 3. After adjusting to the appropriate position, the vertical block 9 and the movable block 11 move to the new position under the drive of the threaded block 8 to continue to clamp and limit the protrusion 501. Therefore, it is convenient for the worktable 3 to flip and adjust the angle, and the protrusion 501, the turntable 5 and the support shaft 4 can be fixed at any position, which improves the precision of the angle adjustment.

[0024] It should be noted that when the small screw 10 is twisted, the movable block 11 will move closer to or further away from the vertical block 9, thereby clamping and releasing the protrusion 501. The surface of the small screw 10 is threaded with a nut to fix the small screw 10, preventing it from rotating freely and increasing stability. At the same time, after the clamping of the protrusion 501 is released, the first servo motor 701 starts, causing the threaded rod 7 to rotate, which makes the threaded block 8, the vertical block 9, and the movable block 11 move accordingly, thus pushing the protrusion 501 to rotate, thereby causing the turntable 5 and the support shaft 4 to rotate, which facilitates the flipping of the worktable 3.

[0025] The front and rear surfaces of the worktable 3 are provided with sliding grooves 12. A slider 13 is slidably connected to the inner side of the sliding groove 12. A folding frame 14 is fixedly connected to the outer side wall of the slider 13. A large screw 15 is threaded through and threaded to the side wall of the folding frame 14. The end of the large screw 15 facing the center of the worktable 3 is rotatably connected to the clamping plate 16 through a bearing. After the large screw 15 is twisted, the clamping plate 16 can be moved laterally to fix the workpiece. The position and number of the folding frame 14 and the clamping plate 16 can be freely set to adapt to different fixing requirements.

[0026] Specifically, such as Figure 1 As shown, a slide rod 161 is fixedly connected to the side wall of the clamping plate 16 below the large screw 15. The slide rod 161 extends horizontally through the surface of the folding frame 14. The slide rod 161 can keep the clamping plate 16 moving horizontally, which improves the stability of the clamping plate 16. Furthermore, the slide rod 161 is long enough that the clamping plate 16 will not slide out of the folding frame 14 when it moves to the center of the worktable 3.

[0027] It is worth noting that, such as Figure 1 As shown, a top groove 17 is horizontally opened in the center of the top of the worktable 3. A double-acting lead screw 18 is rotatably connected to the inner side of the top groove 17. Side plates 19 are threaded through both sides of the surface of the double-acting lead screw 18 and are threaded to the side plates 19. After the double-acting lead screw 18 rotates, the side plates 19 will move relative to each other, thereby fixing the workpiece from the left and right directions. The bottom protrusion of the side plate 19 is located in the top groove 17 and is threaded to the double-acting lead screw 18.

[0028] It is worth noting that, such as Figure 1 and Figure 2 As shown, a servo motor 701 is fixedly connected to the outer wall of one end of the adjustment groove 6. The output end of the drive shaft of the servo motor 701 is fixedly connected to one end of the threaded rod 7. When the servo motor 701 is started, it will drive the threaded rod 7 to rotate. The servo motor 701 is a motor with a self-locking function, so it can ensure that the threaded rod 7 will not rotate when it is not in use, thereby increasing the stability of the threaded block 8, the vertical block 9 and the movable block 11, and ensuring the stability of the worktable 3.

[0029] It is worth noting that, such as Figure 2 As shown, the side wall of the slider 13 below the folding frame 14 is threaded with a compression bolt 131. The bottom of the clamping plate 16 is in contact with the surface of the worktable 3, and the outer end of the large screw 15 is connected to a crank 151, which makes it convenient to manually rotate and adjust the position of the clamping plate 16. After the compression thread is tightened, it will tightly squeeze the slider 13 into the current position of the slide groove 12, so that it remains stable and does not slip, which increases the stability of the folding frame 14 and the clamping plate 16.

[0030] It is worth noting that, such as Figure 1 and Figure 3As shown, an installation groove 20 is provided at the edge of the top surface of the worktable 3 on one side of the top groove 17. A second servo motor 181 is fixedly connected to the inner wall of the installation groove 20. The output end of the drive shaft of the second servo motor 181 is fixedly connected to one end of the bidirectional lead screw 18. When the second servo motor 181 is started, it drives the bidirectional lead screw 18 to rotate, causing the side plate 19 to move, thereby cooperating with the clamping plate 16 to fix the workpiece from four directions.

[0031] In actual use, the worktable 3 requires the support shaft 4 to rotate when it rotates. One of the support shafts 4 has a turntable 5 connected to its outer end. The turntable 5 has protrusions 501 on its surface edge. Therefore, during the rotation process, both the turntable 5 and the protrusions 501 rotate. The vertical block 9 and the movable block 11 change their distance under the adjustment of the small screw 10, thus clamping the protrusions 501 and keeping the turntable 5 and support shaft 4 fixed. When the worktable 3 needs to be rotated or its angle adjusted, the small screw 10 can be turned first to separate the vertical block 9 and the movable block 11. Then, the support shaft 4 and the turntable 5 rotate. After the rotation and angle adjustment are completed to the appropriate position, the vertical block 9 and the movable block 11... Block 11, driven by threaded block 8, reaches a new position to continue clamping and limiting the protrusion 501. This facilitates the flipping and angle adjustment of the worktable 3, and allows the protrusion 501, turntable 5, and support shaft 4 to be fixed at any position, improving the precision of angle adjustment and adapting to different work requirements. The convenience and practicality of the device are enhanced. Slider 13 can slide into the slide groove 12. After sliding to a suitable position and fixing it, the large screw 15 can drive the clamping plate 16 to clamp the workpiece. The position and number of the folding frame 14 and clamping plate 16 can be freely set, thereby adapting to different fixing requirements and improving the practicality of the device.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
