This structure can effectively drive the adjustment structure to move through the first slider 6, and can effectively fix and adjust the fixture, thereby improving the applicability and operability of the device.

[0032] Specifically, the support frame 7 is movably connected to the support column 10, so that the support frame 7 can be adjusted and moved relative to the support column 10, the second screw rod 8 passes through the threaded connection to the support column 10, the top of the first slider 6 is fixedly connected to one side of the lower surface of the support column 10, and the shape of the support frame 7 is "L" type.

[0033] Specifically, a telescopic spring 15 is fixedly installed on one side of the clamping block 14, and an arc plate 16 is fixedly installed on one side of the telescopic spring 15. The number of the telescopic springs 15 is four groups, and the preferred material of the arc plate 16 is rubber. The telescopic spring 15 can provide appropriate pressure so that the clamping block 14 can effectively clamp the workpiece to ensure that it is firmly fixed in the desired position. The telescopic spring 15 can maintain uniform clamping pressure and improve the stability and uniformity of clamping. Rubber is preferred as the material of the arc plate 16, which helps to provide a good buffering effect and reduce damage to the workpiece surface.

[0034] Specifically, the first slide groove 13 is slidably connected with the clamping block 14. This structural design enables the clamping block 14 to slide freely in the first slide groove 13, thereby improving the operating efficiency. A screw 17 is threadedly connected to one side of the clamping block 14, and an internally threaded sleeve 18 is threadedly connected to the surface of the screw 17. One side of the clamping block 14 is movably connected to the internally threaded sleeve 18.

[0038] Working principle: When in use, place the jig in the middle position of the workbench 1, start the dual-axis drive motor 4, so that it drives the adjustment structure to move, and move to the appropriate position according to the processing requirements. The clamping block 14 drives the arc plate 16 to fix the jig, and the internal threaded sleeve 18 can be adjusted. The internal threaded sleeve 18 drives the threaded rod 17 to rotate outward, so that the clamping block 14 and the arc plate 16 are separated. It can be effectively adjusted and fixed according to the shape and size of the jig. Control the motor 9 to rotate the second screw rod 8, so as to adjust the height of the support column 10 to adapt to the adjustment during the processing of different jigs. Start the controller 28, and ensure that the operator 29 is correctly connected to the controller 28. The hydraulic cylinder 25 is controlled by the operator 29 to make the pressure plate 27 clamp the workpiece to ensure that it is firmly fixed in the required position, and according to the processing requirements, the angle of the rotating workpiece is adjusted by the turntable 23 to ensure that processing operations can be performed at different angles.
