[0014] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0015] In the present invention, the first servo motor 4, the second servo motor 8 and the hydraulic cylinder 10 are all connected to the external electronic control system through wires. The above devices and connection methods are all existing technologies and will not be described in detail here.

[0016] According to the instruction manual Figure 1It can be seen that when the present invention is in use, the fixture is first installed on a CNC machine tool, and the machine tool is provided with a third servo motor capable of driving the first rotating shaft 11 or the second rotating shaft 12 to rotate. Secondly, the blank 13 is placed in the frame 1 and is located between a pair of first sliders 2 and a pair of second sliders 7. The first servo motor 4 provided on the frame 1 and the second servo motor 8 on the movable plate 5 are started. When the first servo motor 4 rotates, the output end drives the connected first forward and reverse screw 3 to rotate. The first forward and reverse screw 3 causes the pair of first sliders 2 threadedly connected to the forward and reverse threads thereof to slide toward or away from each other in the first slide groove 1-1, so that the pair of first sliders 2 are aligned with a position close to the edge of one side of the blank 13. The second servo motor 8 adjusts the distance between the pair of second sliders 7 in the same way. Again, the hydraulic cylinder 1 provided on the connecting frame 9 is started. 0, the telescopic end of the hydraulic cylinder 10 extends outward, so that the telescopic end of the hydraulic cylinder 10 pushes the movable plate 5 to move in the direction of the blank 13, and then the pair of first sliders 2 and the pair of second sliders 7 clamp and fix the blank 13. Finally, the CNC machine tool is used to process the blank 13. After the processing of one side of the blank 13 is completed, the third servo motor drives the frame 1 to rotate 180 degrees to turn the blank 13 over, so that the machine tool processes the other side of the blank 13; the hydraulic cylinder 10 of the utility model drives the movable plate 5 to move to fix the first slider 2 and the second slider 7 to the blank 13. After the processing of one side of the blank 13 is completed, the third servo motor drives the frame 1 to flip 180 degrees to process the other side of the blank 13. There is no need to manually flip and adjust the position of the blank 13, which saves time and effort for personnel and improves the processing efficiency.

[0017] There is a possible implementation method in which a first connecting block is provided in the middle position of the movable plate 5 near the side of the hydraulic cylinder 10, and the telescopic end of the hydraulic cylinder 10 is connected to the first connecting block. When the telescopic end of the hydraulic cylinder 10 moves, the telescopic end of the hydraulic cylinder 10 drives the first connecting block to move, and the first connecting block drives the movable plate 5 to move.

[0018] There is a possible implementation, in which a second connecting block is provided at the middle position outside the frame of the frame 1 where the first sliding groove 1 - 1 is provided, the second rotating shaft 12 is provided on the second connecting block, and the second connecting block connects the second rotating shaft 12 and the frame 1.
