[0042] A connecting rod 13, the connecting rod 13 is slidably arranged on the surface of the baffle plate 8, and the end of the connecting rod 13 is plugged and connected with the auxiliary block 11, and a receiving plate 14, the receiving plate 14 is slidably arranged inside the working plate 4, and drainage ports 16 are opened on both sides of the working plate 4;

[0043] The long pin 15 is rotatably arranged inside the baffle plate 8 , and a gear 20 is fixedly connected to the surface of the long pin 15 . Both sides of the receiving plate 14 are inclined, and the receiving plate 14 is symmetrically distributed about the center of the working plate 4 .

[0044] During operation, the workpiece is clamped and fixed on the workbench 7, and the height of the grinding wheel assembly 6 on the work box 2 is controlled by the Z axis. Then the hydraulic system of the equipment box 1 is started. At this time, the working plate 4 slides back and forth on the equipment box 1, and the grinding wheel assembly 6 completes the processing of the workpiece. At the same time, the processing process is cooled through the coolant output pipe 5 to ensure the normal progress of the work. The debris in the processing process will fall on the receiving plate 14, and both sides of the receiving plate 14 are inclined, so the debris will slide down quickly and gather, which is convenient for collection by the staff.

[0045] Embodiment 2: Different from Embodiment 1, the extrusion rod 23 is provided to enable the receiving plate 14 to perform reciprocating linear motion in the vertical direction, so that the debris can slide down more quickly. Figure 2-Figure 6 As shown:

[0046] The upper surface of the equipment box 1 is fixedly connected with fixing rods 12 corresponding to the auxiliary block 11 , and the fixing rods 12 are symmetrically distributed about the center of the auxiliary block 11 , and both sides of the auxiliary block 11 are inclined.

At this time, the first spring 19 will be squeezed, and when the working plate 4 drives the auxiliary block 11 not to contact the fixed rod 12, the auxiliary block 11, the connecting rod 13 and the movable block 9 will move back under the action of the first spring 19, and the limit rod 10 makes the movable block 9 move only in the horizontal direction. Repeat the above process, the connecting rod 13 and the tooth block 17 move in the horizontal direction. The long pin 15 rotates on the surface of the baffle plate 8 under the action of the tooth block 17 and the gear 20, and then the long pin 15 drives the disc 22 and the extrusion rod 23 to rotate synchronously. When the extrusion rod 23 rotates to contact the column 24, the column 24 and the receiving plate 14 are pushed down by the extrusion rod 23. At this time, the second spring 25 is squeezed, and when the extrusion rod 23 rotates to not contact the column 24, the column 24 and the receiving plate 14 return to their original positions under the action of the second spring 25, and then the receiving plate 14 makes reciprocating linear motion in the vertical direction, that is, the receiving plate 14 is in a vibrating state, which is convenient for the debris to slide down and concentrate quickly, and then it is more convenient to collect the debris.

[0052] Embodiment 3: Different from Embodiment 2, the positioning rod 21 is provided to limit the maximum distance of the receiving plate 14 rising, thereby ensuring stability. Figure 3 As shown:
