By controlling the processing table 10 to slide inside the guide groove 9, it is convenient to move the external material to the bottom of the processing head 19 for processing. During processing, the flexible support plate 16 is directly pushed by the cylinder 15 to fix the material, which is easy to operate. At the same time, the material debris generated during processing is collected in the inclined guide groove 9 and is taken out of the equipment by the liquid sprayed by the cooling nozzle.

[0025] like Figure 2 and 3 As shown, a guide groove 9 is opened on one side of the device body 1, and the lower part of the inner wall of the guide groove 9 is inclined. The processing table 10 is slidably installed inside the guide groove 9. A movable groove 11 is opened on one side of the inner wall of the guide groove 9. The screw 12 is rotatably installed inside the movable groove 11. The second motor 14 is installed on the device body 1;

[0026] The transmission mechanism includes a slider 4, which is slidably mounted on the guide rail 3. A shell 5 is installed on one side of the guide rail 3.

When the fixing component is working, multiple cylinders 15 push the flexible support plate 16 to fix the workpiece. The buffer spring 21 in the hollow plate 20 plays a buffering role to reduce the impact on the workpiece. The sliding block 23 on the mounting plate 24 can slide on the slide rail 22 and is fixed in position by the first bolt. The accordion protective cover 25 in the sliding groove 2 protects the sliding parts. The heat dissipation device 26 on the top of the shell 5 is used for equipment heat dissipation.
