[0022] When it is necessary to place or take out the drill bit milling cutter 17 in the storage box 16, the second motor 18 is started, and the output shaft of the second motor 18 rotates clockwise to drive the gear 19 to rotate clockwise. The gear 19 rotates clockwise to make the slide 15 move right along the slide slot, and the slide 15 moves right to drive the storage box 16 to move right. After the storage box 16 moves right, passes through the square hole at the lower right side of the cover 3 and moves to the right side of the U-shaped plate 25, the second motor 18 is turned off. At this time, the cleaned drill bit milling cutter 17 can be taken out, and after the drill bit milling cutter 17 that needs to be cleaned is put into the storage box 16, the second motor 18 is started to make the output shaft of the second motor 18 rotate counterclockwise, and the output shaft of the second motor 18 rotates counterclockwise to drive the gear 19 to rotate counterclockwise, and the gear 19 rotates counterclockwise to make the slide 15 move left along the slide slot from the right side of the U-shaped plate 25. The slide 15 moves left and drives the storage box 16 to move left to the left side of the slide slot to resume its original position, thereby facilitating the next cleaning process.

[0023] It also includes a limit switch 24, and the left side of the slide of the workbench 1 and the right side of the U-shaped plate 25 are fixedly connected to the limit switch 24. When the slide 15 moves to the left side of the slide, the slide 15 touches the left limit switch 24 to turn off the second motor 18, and when the slide 15 moves to the right side of the U-shaped plate 25, the slide 15 touches the right limit switch 24 to turn off the second motor 18, making the control of the second motor 18 more convenient.

When the second motor 18 is started to move the slide 15 to the right to the right side of the U-shaped plate 25, the right end of the fixed rod 21 contacts the stopper 23 to move the fixed rod 21 backward, the fixed rod 21 moves backward to compress the coil spring 22, the fixed rod 21 moves backward to release the drill bit milling cutter 17 in the storage box 16, and the second motor 18 is started again to reverse the second motor 18, so that the slide 15 moves to the left, the fixed rod 21 is away from the stopper 23, and the spring returns to its original state to move the fixed rod 21 forward, and the fixed rod 21 moves forward to clamp the drill bit milling cutter 17 in the storage box 16 to prevent the drill bit milling cutter 17 from being moved out of the storage box 16 by the brush 14.

[0025] Also include a handle 5, the front side of the sliding door 4 is fixedly connected with the handle 5. When the sliding door 4 needs to be moved, the sliding door 4 can be moved by pulling the handle 5, and the handle 5 can make the movement of the sliding door 4 more convenient.

[0026] When it is necessary to clean the burrs on the drill bit milling cutter 17, the sliding door 4 is opened, the drill bit milling cutter 17 to be cleaned is placed in the storage box 16, the sliding door 4 is closed, the high-speed motor 13 and the cylinder 11 are started, and the output shaft of the high-speed motor 13 drives the brush 14 to rotate, and the piston rod of the cylinder 11 moves downward to drive the fixed block 12 to move downward, and the fixed block 12 moves downward to drive the high-speed motor 13 to move downward, so that the brush 14 contacts the drill bit milling cutter 17, and the brush 14 scrapes off the burrs on the drill bit milling cutter 17. After the burrs on the drill bit milling cutter 17 are cleaned, the high-speed motor 13 is closed, and the cylinder 11 is started, so that the piston rod of the cylinder 11 moves upward to drive the fixed block 12 to move upward, and the fixed block 12 moves upward to drive the high-speed motor 13 to move upward, so that the brush 14 is away from the drill bit milling cutter 17, the sliding door 4 is opened, and the processed drill bit milling cutter 17 is taken out, and the automatic cleaning of the burrs on the drill bit milling cutter 17 is completed once, without the need for manual hand-held cleaning equipment.

[0027] When deburring the drill bit and milling cutter 17, start the first motor 8, the output shaft of the first motor 8 drives the second connecting rod 10 to rotate, the rotation of the second connecting rod 10 drives the first connecting rod 9 to rotate, the rotation of the first connecting rod 9 drives the slider 7 to move back and forth left and right along the through groove, the left and right movement of the slider 7 drives the cylinder 11 to move left and right, the left and right movement of the cylinder 11 drives the fixed block 12 to move left and right, the left and right movement of the fixed block 12 drives the high-speed motor 13 to move left and right, the left and right movement of the high-speed motor 13 drives the brush 14 to move left and right, so that the brush 14 can clean the drill bit and milling cutter 17 in the storage box 16 in batches.

[0028] When it is necessary to place or take out the drill bit milling cutter 17 in the storage box 16, the second motor 18 is started, and the output shaft of the second motor 18 rotates clockwise to drive the gear 19 to rotate clockwise. The gear 19 rotates clockwise to make the slide 15 move right along the slide slot, and the slide 15 moves right to drive the storage box 16 to move right. After the storage box 16 moves to the right and passes through the square hole in the lower right part of the cover 3, the second motor 18 is turned off. At this time, the cleaned drill bit milling cutter 17 can be taken out, and the drill bit milling cutter 17 that needs to be cleaned and processed can be put into the storage box 16. After the operation is completed, the second motor 18 is started to make the output shaft of the second motor 18 rotate counterclockwise, and the output shaft of the second motor 18 rotates counterclockwise to drive the gear 19 to rotate counterclockwise, and the gear 19 rotates counterclockwise to make the slide 15 move left along the slide slot, and the slide 15 moves left to drive the storage box 16 to move left to the left side of the slide slot to restore to its original position, so as to facilitate the next cleaning process.

[0029] When the slide 15 moves to the left to the left side of the slide slot, the slide 15 touches the left limit switch 24, and the left limit switch 24 controls the second motor 18 to turn off. When the slide 15 moves to the right to the right side of the U-shaped plate 25, the slide 15 touches the right limit switch 24, and the right limit switch 24 controls the second motor 18 to turn off, making the control of the second motor 18 more convenient.

[0030] When the slide 15 moves to the right to the right side of the U-shaped plate 25, the right end of the fixing rod 21 contacts the stopper 23, causing the fixing rod 21 to move backward. The backward movement of the fixing rod 21 causes the spiral spring 22 to contract, thereby releasing the drill bit and milling cutter 17 in the storage box 16. When the slide 15 moves to the left, the fixing rod 21 no longer contacts the stopper 23, and the spring returns to its original state, causing the fixing rod 21 to move forward to clamp the drill bit and milling cutter 17 in the storage box 16, thereby preventing the brush 14 from moving the drill bit and milling cutter 17 out of the storage box 16 when cleaning the burrs on the drill bit and milling cutter 17.

[0031] When the sliding door 4 is moved, the handle 5 can make the movement of the sliding door 4 more convenient.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
