[0006] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0007] A self-adjusting fixture tooling includes a placement table arranged on the top of a workbench. A number of pairs of support seats are arranged on the workbench. The support seats are distributed circumferentially along the placement table. The top of one side of the support seat close to the placement table is rotatably connected with a clamping plate. A first electric telescopic rod is rotatably connected between the top of the other side of the clamping plate and the top of the support seat;

[0008] A through groove is opened on the workbench. The bottom of the support seat is vertically connected with a support column passing through the through groove. The bottom of the workbench is provided with a bottom plate. The top of the bottom plate is telescopically connected with an installation base. A lead screw is threadedly connected between the support columns at the bottom of each pair of support seats. The threads on the outer wall of the lead screw are symmetrically arranged;

The driving motor is fixedly connected to the top of the mounting base. A control box is also connected to the workbench. A controller is arranged inside the control box. The driving motor, the first electric telescopic rod are connected to the controller.

[0010] Optionally, the lower end of the clamping plate is rotatably connected to the top of the support seat through a second hinge seat, and an anti-slip strip is fixedly connected to the outer wall of the clamping plate.

[0011] Optionally, the ends of the first electric telescopic rods are all rotatably connected to first hinge seats, and the two first hinge seats are sequentially connected to the upper side of the clamping plate and the top of the support seat.

[0012] Optionally, a guide rod is fixedly connected inside the through groove, and the guide rod penetrates through the support column.

Specific embodiments

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a self-adjusting fixture tooling, including a placement table 20 arranged on the top of a workbench 1. A number of pairs of support seats 3 are arranged on the workbench 1, and the support seats 3 are distributed along the circumferential direction of the placement table 20. The top of the placement table 20 is used for placing workpieces to be processed. In actual use, in order to improve the stability of workpiece placement, an anti-slip pad is installed on the top of the placement table 20, increasing the friction between the workpiece and the placement table 20.

[0022] As Figure 1 、 2 shown, a clamping plate 19 is rotatably connected to the top of the side of the support seat 3 close to the placement table 20. The lower end of the clamping plate 19 is rotatably connected to the top of the support seat 3 through a second hinge seat 7. An anti-slip strip 2 is fixedly connected to the outer wall of the clamping plate 19. When the clamping plate 19 contacts the workpiece to be processed, the provided anti-slip strip 2 effectively increases the friction between it and the surface of the workpiece, further improving the clamping stability. In order to facilitate the processing of workpieces with different shapes, a first electric telescopic rod 9 is rotatably connected between the top of the other side of the clamping plate 19 and the top of the support seat 3; the ends of the first electric telescopic rod 9 are both rotatably connected to a first hinge seat 4, and the two first hinge seats 4 are sequentially connected to the upper side of the clamping plate 19 and the top of the support seat 3. The first electric telescopic rod 9 pushes the clamping plate 19 to rotate along the second hinge seat 7, so as to adjust the angle formed between the clamping plate 19 and the placement table 20, meet the requirements of different side walls of the workpiece to be processed, and thus improve the practicability of the device.

[0023] As Figure 1 、 3As shown in the figure, a through groove 5 is provided on the workbench 1. The bottom of the support base 3 is vertically connected with a support column 6 penetrating through the through groove 5. A guide rod 8 is fixedly connected in the through groove 5, and the guide rod 8 penetrates through the support column 6, ensuring the stable sliding of the support column 6 in the through groove 5 and improving the overall stability of the device. A bottom plate 17 is provided at the bottom of the workbench 1. The top of the bottom plate 17 is telescopically connected with an installation base 12. A second electric telescopic rod 13 is connected between the installation base 12 and the bottom plate 17. The second electric telescopic rod 13 is located directly below the installation base 12. The second electric telescopic rod 13 is connected to the controller. The bottom of the installation base 12 is connected with a plurality of first sleeves 16. The lower end of the first sleeve 16 is coaxially connected with a second sleeve 18. The second sleeve 18 is fixedly connected to the top of the bottom plate 17. Under the push of the second electric telescopic rod 13, the stable lifting of the installation base 12 can be realized, and then the gap formed between the support base 3 and the workbench 1 can be adjusted, which can meet the use of workpieces that need to be fixed from the top, bringing great convenience to the processing operation of users.

[0024] As Figure 1 , 2 shown in the figure, a lead screw 11 is threadedly connected between the support columns 6 at the bottom of each pair of support bases 3. The threads on the outer wall of the lead screw 11 are symmetrically arranged. The end of the lead screw 11 is connected to the installation base 12 through a bearing seat 14, and one end of the lead screw 11 is fixedly connected with a driving motor 15. The driving motor 15 is fixedly connected to the top of the installation base 12.

[0025] In summary, for this self-adjusting fixture tooling, during use, a control box 10 is also connected to the workbench 1. A controller is arranged in the control box 10. The driving motor 15 and the first electric telescopic rod 9 are connected to the controller. The driving motor 15 controls the rotation of the lead screw 11. Since the threads on the outer wall of the lead screw 11 are symmetrically arranged, the two support columns 6 thereon can be driven to slide towards each other, and then the workpiece placed on the top of the placement table 20 can be clamped. According to the angle between the side wall of the workpiece and the workbench 1, the first electric telescopic rod 9 is controlled to push the clamping plate 19 to rotate along the second hinge seat 7, which can improve the clamping stability. At the same time, if the workpiece needs to be pressed and fixed from the top, the second electric telescopic rod 13 is controlled to push the support base 3 to slide upward, and the support column 6 is controlled to slide, so as to realize the top clamping and fixing of the workpiece. The utility model not only has a simple structure and is convenient for adjustment, but also can meet the clamping and fixing of different workpieces, greatly improving the practicability of the device.
