[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: a mechanical fixture for automated accessories, including a base 1, which provides support and stability. The inner wall of the top of the base 1 is rotatably connected to a rotating column 2, allowing the placement table 3 on the top thereof to rotate. The bottom end of the rotating column 2 is fixedly connected to the placement table 3 for placing and supporting accessories. The inner wall of the placement table 3 is provided with a clamping assembly for fixing the accessories. The bottom right end of the placement table 3 is fixedly connected to a driving motor 4 for providing power for the clamping assembly. The top of the placement table 3 is provided with a guide groove 6 for guiding the moving direction of the slider 53. The inner wall of the placement table 3 A clamping assembly is provided, which includes a bidirectional threaded rod 51. The right side of the bidirectional threaded rod 51 is fixedly connected to the left side of the output shaft of the driving motor 4. When the bidirectional threaded rod 51 rotates, the slide plate 52 threadedly connected thereto will move horizontally and stably along different directions. The outer walls on both sides of the bidirectional threaded rod 51 are rotatably connected to the inner wall of the placement table 3. The outer wall of the bidirectional threaded rod 51 is threadedly connected with a slide plate 52 for carrying a slider 53 and a moving block 54, and horizontal movement is achieved through a threaded connection with the bidirectional threaded rod 51. The outer surface of the slide plate 52 slides on the inner wall of the placement table 3.

[0034] Reference Figure 3 - Figure 5The inner wall of the top of the slide plate 52 is slidably connected with a slide block 53. The slide block 53 is provided with four groups for driving four groups of moving blocks 54 to move smoothly to clamp the accessories, thereby improving the applicability of the device. The top of the slide block 53 is fixedly connected with a moving block 54. The moving block 54 is horizontally tilted and fixed with the slide block 53. The moving block 54 ensures that the slide bar 55 slides smoothly in the horizontal direction. The outer wall of the top of the slide block 53 slides on the inner wall of the guide groove 6, so that the slide bar 53 can slide on the inner wall of the slide plate 52. The inner wall of the moving block 54 is slidably connected with a slide bar 55, which slides on the inner wall of the moving block 54. The slide bar 55 is set in a U shape, which can fix two groups of limit columns 58 to improve the clamping effect of the accessories. The slide bar 55 is elastically connected to the moving block 54 through a compression spring 56. The elastic force of the compression spring 56 provides a reset force, so that the slide bar 55 can quickly return to the position before clamping. The left side of the slide bar 55 is fixedly connected to a limit column 58 for directly contacting and fixing the accessories. The left side of the limit column 58 is set to be made of rubber material. The rubber material is used to increase the friction between the accessories, prevent sliding, and reduce damage to the workpiece. A contact switch 57 is fixedly installed on the inner wall of the moving block 54 near the right side of the slide bar 55. When the slide bar 55 moves to a certain extent, the contact switch 57 will be triggered, thereby stopping the drive motor 4 from rotating, reducing the damage to the accessories caused by excessive clamping.

[0035] Reference Figure 2 and Figure 6 The swivel assembly 77 is provided at the bottom end of the rotating column 2, and the rotating assembly includes a limit block 71. The outer wall of the rear side of the limit block 71 is slidably connected to the inner wall of the rotating column 2 to limit the rotation of the rotating column 2. The limit block 71 and the rotating column 2 are elastically connected by a return spring 72. One end of the return spring 72 is fixedly connected to the rear side of the limit block 71, and the other end of the return spring 72 is fixedly connected to the inner wall of the rotating column 2. When the limit block 71 is pushed and the return spring 72 is compressed, the return spring 72 will generate an elastic force, which will squeeze the limit block 71 into the next limit groove through the elastic force. The rotating column 2 is provided with a limit groove near the outer side of the limit block 71, and the limit groove is provided with a Multiple groups are provided, which are used in conjunction with the limit block 71 to limit the rotating column 2. The outer side of the limit block 71 slides on the inner wall of the limit groove. The bottom end of the rotating column 2 is rotatably connected to a rotating ball 73, and the bottom end of the rotating ball 73 slides on the inner wall of the base 1. The rotating ball 73 can reduce the friction between the rotating column 2 and the base 1, so that the rotating column 2 can rotate more smoothly. Multiple groups of limit blocks 71 and return springs 72 are provided, and the multiple groups of limit blocks 71 and return springs 72 are evenly distributed along the center line of the rotating column 2. The angle of the placing table 3 can be freely and quickly adjusted, which improves the operating convenience and flexibility of the device, thereby improving the working efficiency of the device.

[0036] Working principle: When in use, first place the accessory in the middle of the placement table 3, then start the drive motor 4, and drive the bidirectional threaded rod 51 to rotate on the inner wall of the placement table 3 through the output shaft of the drive motor 4, and the bidirectional threaded rod 51 drives the two groups of slide plates 52 to move in opposite directions through the threads, so that the slide plate 52 slides on the inner wall of the placement table 3, and drives the four groups of slide blocks 53 to move toward the middle of the placement table 3 through the guide groove 6, and slide on the inner wall of the slide plate 52 at the same time. When multiple groups of limit columns 58 clamp the accessory, the reverse force drives the slide bar 55 to slide on the inner wall of the moving block 54, and compresses the compression spring 56. When the slide bar 55 contacts the contact switch 57, it will cause the drive motor 4 to stop rotating, so that the slide plate 52 will no longer move, thereby preventing excessive extrusion from causing damage to the accessories and edges.

[0037] When it is necessary to adjust the horizontal angle of the placement table 3, the placement table 3 is pushed, and the limiting block 71 is made to slide from the inner wall of the limiting groove through the thrust, and the limiting block 71 is made to slide out of the limiting groove through the arc surface of the inner wall of the limiting groove, and the reset spring 72 is squeezed. At the same time, when the rotating column 2 rotates, it drives the rotating ball 73 to slide on the inner wall of the base 1, reducing the friction force, so that the rotating column 2 can rotate more smoothly, and the elastic force of the reset spring 72 is used to make the limiting block 71 slide into the limiting groove of the required angle to adjust the angle of the placement table 3.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
