[0022] like Figures 1 to 3 As shown, a machine tool processing fixture comprises a base plate 1, two clamping plates 1 2 are arranged on the top of the base plate 1, two groups of moving components 3 are arranged inside the base plate 1 for driving the two clamping plates 1 2 to move respectively, a servo motor 1 4 is fixedly installed on the side of the two clamping plates 1 2 away from each other, the output end of each servo motor 1 4 passes through the corresponding clamping plate 1 2 and is fixedly connected to a clamping plate 2 5, a mounting plate 6 is fixedly installed on the rear side wall of the base plate 1, an electric telescopic rod 1 7 is fixedly installed on the output end of the mounting plate 6, an electric telescopic rod 2 8 is fixedly installed on the output end of the electric telescopic rod 1 7, and a servo motor 2 9 is fixedly installed on the output end of the electric telescopic rod 2 8, A U-shaped frame 10 is fixedly installed at the output end of the servo motor 29, and two electric telescopic rods 3 11 are fixedly installed inside the U-shaped frame 10. An L-shaped plate 12 is provided at the output end of each electric telescopic rod 3 11. It should be noted that, first, the rectangular workpiece to be processed is placed between the two clamping plates 2 5, and then the moving component 3 is controlled to make the two clamping plates 1 2 approach each other, and each clamping plate 1 2 drives the adjacent clamping plates 2 5 to move synchronously, and the workpiece is clamped by the two clamping plates 2 5, and then the two servo motors 1 4 are controlled, and each servo motor 1 4 drives the adjacent clamping plates 2 5 to rotate synchronously, so that the workpiece can be rotated. When the workpiece is clamped, it is only necessary to rotate the processing surface upwards. At this time, the processing of the four surfaces of the rectangular body can be automatically switched. If it is necessary to process the two sides close to the two clamping plates 2 5, it is only necessary to control the moving component 3 to make the two clamping plates 1 2 move away from each other. Each clamping plate 1 2 drives the adjacent clamping plates 2 5 to move synchronously, and the clamping of the workpiece can be released. Then the electric telescopic rod 1 7 can drive the electric telescopic rod 2 8 to rise and fall to a suitable height. The electric telescopic rod 2 8 can drive the servo motor 2 9 to move back and forth to a suitable position, so that the workpiece is placed between the two L-shaped plates 12. Each electric telescopic rod 3 11 then drives the adjacent L-shaped plates 12 to approach the workpiece to clamp the workpiece. The electric telescopic rod 1 7 drives the electric telescopic rod 2 8 to rise and fall to a suitable height, controls the servo motor 2 9 to drive the U-shaped frame 10 to rotate 90 degrees, and the U-shaped frame 10 drives the electric telescopic rod 3 11 and the L-shaped plate 12 to rotate, so that the workpiece can be rotated 90 degrees.

[0025] like Figure 3 As shown, the output ends of the two electric telescopic rods 3 11 are fixedly installed with connecting rings 19, and a connecting ring 20 is arranged below each connecting ring 19, and each connecting ring 20 is fixedly connected to the adjacent L-shaped plate 12. Bolts 21 are commonly arranged inside each connecting ring 19 and the adjacent connecting ring 20, and a nut 22 is threadedly connected to each bolt 21. It should be noted that when clamping a cylindrical workpiece, the angles of the two L-shaped plates 12 can be rotated respectively to facilitate clamping the cylindrical workpiece. When the L-shaped plate 12 rotates, the adjacent connecting ring 2 20 is synchronously driven to rotate. After the angle of the L-shaped plate 12 is determined, each connecting ring 20 20 is fixed to the adjacent connecting ring 1 19.

[0026] like Figure 1 As shown, a servo motor 3 23 is fixedly installed on the top of the base plate 1, and a cleaning roller 24 is fixedly installed on the output end of the servo motor 3 23. It should be noted that when the top of the supporting plate 18 drops to correspond to the top of the base plate 1, the servo motor 3 23 can drive the cleaning roller 24 to rotate according to a preset angle, and the cleaning roller 24 is used to clean the debris on the top of the supporting plate 18.

[0027] like Figure 1As shown, the moving component 3 includes a slide groove 301, two slide grooves 301 are opened on the top of the base plate 1, and servo motors 302 are fixedly installed on the left and right side walls of the base plate 1.

If it is necessary to process the two sides that are close to the two clamping plates 2 5, it is only necessary to control the moving component 3 to make the two clamping plates 2 move away from each other, and each clamping plate 2 drives the adjacent clamping plates 2 5 to move synchronously, so as to release the clamping of the workpiece, and then the electric telescopic rod 1 7 can drive the electric telescopic rod 2 8 to rise and fall to a suitable height, and the electric telescopic rod 2 8 can Drive the servo motor 29 to move forward and backward to a suitable position, so that the workpiece is placed between the two L-shaped plates 12, and each electric telescopic rod 3 11 drives the adjacent L-shaped plates 12 to approach the workpiece to clamp the workpiece. Then, the electric telescopic rod 17 drives the electric telescopic rod 28 to rise and fall to a suitable height, and then control the servo motor 29 to drive the U-shaped frame 10 to rotate ninety degrees. The U-shaped frame 10 then drives the electric telescopic rod 3 11 and the L-shaped plate 12 to rotate, so that the workpiece can be rotated ninety degrees. At this time, the two clamping plates 2 are brought close to clamp the workpiece, and each electric telescopic rod 3 11 drives the adjacent L-shaped plates 12 away from the workpiece to release the workpiece.
