A connecting rod 56 is fixedly installed on the side wall of the movable plate 52. The side wall of the fixed rod 54 is fixedly connected to the side wall of the protective plate 4. A plurality of grooves 57 are provided on the upper surface of the fixed rod 54. A positioning pin 59 is rotatably installed on the inner side walls of both sides of the groove 57. A baffle 58 is fixedly installed at one end of the positioning pin 59. Torsion springs 510 are fixedly installed on both side walls of the baffle 58. One end of the torsion spring 510 is fixedly connected to the inner side walls of both sides of the groove 57.

[0029] The specific implementation method is as follows: Before the numerical control machine tool processes, close the two protective plates 4. When the protective plates 4 move, they will drive the fixed rod 54 to move synchronously. At this time, under the action of the connecting rod 56, the baffle 58 will be embedded in the groove 57 under the limit of the positioning pin 59. After the connecting rod 56 passes by, under the action of the torsion spring 510, the baffle 58 will rebound to its original position. After the processing is completed, move the protective plates 4 to both sides of the machine base 1. At this time, after the baffle 58 is blocked, when moving, the connecting rod 56 drives the movable plate 52 to rotate in the mounting clip 51. After the connecting rod 56 moves past the baffle 58, under the action of the connecting spring 55, the movable plate 52 drives the knocking rod 53 to knock on the fixed plate 2. The fixed plate 2 that receives the vibration will drive the workpiece to vibrate, and the debris on the fixed plate 2 and the workpiece will be shaken onto the filter plate 6. The cooling water falls into the machine base 1 and is discharged through the drain pipe.

[0030] The clamping assembly 3 includes a mounting cover 35. The side wall of the mounting cover 35 is fixedly connected to the side wall of the machine base 1. A driving motor is fixedly installed on the inner wall of the mounting cover 35. The output end of the driving motor is fixedly installed with a threaded column 33. A moving column 31 is threadedly installed on the outer surface of the threaded column 33. A limiting strip 34 is slidably installed on the inner wall of the moving column 31. The lower surface of the limiting strip 34 is fixedly connected to the inner wall of the placement groove. The upper surface of the moving column 31 is fixedly installed with a positioning plate 32. Stroke grooves 36 are provided on the side walls of the positioning plate 32 and the fixed plate 2.

Support plates 38 are fixedly installed on the side walls of the positioning plate 32 and the fixed plate 2. Friction pads 39 are fixedly installed on the upper surface of the support plate 38 and the lower surface of the pressing plate 311.

[0031] The specific implementation method is as follows: The driving motor in the mounting cover 35 drives the threaded column 33 to rotate. Under the action of the thread, the moving column 31 drives the positioning plate 32 to move under the action of the limiting strip 34. After the positioning plate 32 moves to an appropriate position, one end of the workpiece is in contact with the side wall of the positioning plate 32, and the other end is in contact with the side wall of the fixed plate 2. Then rotate the self-locking threaded rod 37. Under the action of the thread, the threaded plate 310 drives the pressing plate 311 to press the workpiece on the support plate 38, and the friction pads 39 increase the friction force between the workpiece and the pressing plate 311 and the support plate 38.

[0032] Working principle: The driving motor installed inside the mounting cover 35 drives the threaded column 33 to rotate. Under the action of the thread, the moving column 31 drives the positioning plate 32 to move under the action of the limiting strip 34. After the positioning plate 32 moves to an appropriate position, one end of the workpiece contacts the side wall of the positioning plate 32, and the other end contacts the side wall of the fixed plate 2. Then, the self-locking threaded rod 37 is rotated. Under the action of the thread, the threaded plate 310 drives the pressing plate 311 to press the workpiece on the support plate 38. The friction pad 39 increases the friction force between the workpiece and the pressing plate 311 and the support plate 38. Before the numerical control machine tool processes, the two protective plates 4 are closed. When the protective plate 4 moves, it will drive the fixed rod 54 to move synchronously. At this time, under the action of the connecting rod 56, the baffle 58 will be embedded in the groove 57 under the limit of the positioning pin 59. After the connecting rod 56 passes, under the action of the torsion spring 510, the baffle 58 will rebound to its original position. After the processing is completed, the protective plate 4 is moved to both sides of the machine base 1. At this time, when the baffle 58 is blocked, during the movement, the connecting rod 56 drives the movable plate 52 to rotate in the mounting clip 51. After the connecting rod 56 moves past the baffle 58, under the action of the connecting spring 55, the movable plate 52 drives the knocking rod 53 to knock on the fixed plate 2. The fixed plate 2 that receives the vibration will drive the workpiece to vibrate, and the debris on the fixed plate 2 and the workpiece will be shaken onto the filter plate 6. The cooling water falls into the machine base 1 and is discharged through the drain pipe.
