Through the arrangement of the vacuum cleaner 16 and the cam 14 and other structures, after the gear shaft is processed, the main shaft moves upward, so that the spur gear 6 rotates accordingly, so that the second rack 8 moves downward, and then the vacuum tube 18 is pushed by the cam 14 to remove the debris on the surface of the workbench, so that the debris cleaning is more convenient, thereby improving the production efficiency.

[0022] See also Figure 2 Oil holes 4 are provided on one side of the fixed block 3 and on the top of the shell 1. Through the arrangement of the shell 1 and the oil holes 4, during the main shaft rising process, some internal parts such as the spur gears 6 will be worn. Therefore, oil holes 4 are provided on the fixed block 3 and the shell 1, and lubricating oil is added through the oil holes 4, thereby reducing the wear between the parts and extending the service life of the equipment.

[0023] See also Figure 1-3 A through groove is provided inside the second rack 8, the dust suction hard pipe 18 is located inside the through groove, a straight groove is provided inside the fixed block 3, the first rack 5 is slidably connected inside the straight groove, one of the oil holes 4 is connected to the straight groove, a square groove is provided inside the housing 1, the first bevel gear 10, the second bevel gear 12 and the driven wheel 11 are all rotatably installed inside the square groove, the square groove is connected to another oil hole 4, a circular groove is provided inside the housing 1, the cam 14 is rotatably installed inside the circular groove, a square hole is provided inside the housing 1, part of the telescopic rod 15 is slidably connected inside the square hole, and the square hole is connected to the circular groove.

[0024] The specific implementation process of the utility model is as follows: the gear shaft is fixed on the clamping claw, and then the spindle box 2 is lowered to process it. When the processing is completed, the spindle rises, and the first rack 5 on one side of the spindle moves upward, thereby driving the spur gear 6 to rotate, and the second rack 8 moves downward accordingly. The driving wheel 7 also drives the driven wheel 11 to rotate through the synchronous belt 9, so that the first bevel gear 10 rotates with the driven wheel 11. Since the first bevel gear 10 is meshed and connected with the second bevel gear 12, the second bevel gear 12 drives the rotating shaft 13 to rotate, so that the cam 14 also rotates accordingly, and the cam 14 pushes the telescopic rod 15 to move to one side. The telescopic rod 15 pushes the dust suction hard pipe 18, so that the dust suction hard pipe 18 tilts and swings, so as to absorb the chips on the surface of the workbench. During the rising process of the second rack 8, since the dust suction hard pipe 18 is stuck in the inside of the fixed block 3, the telescopic rod 15 will retract itself and cannot push the dust suction hard pipe 18. Only when it descends can the telescopic rod 15 push it to absorb the chips;

[0025] Furthermore, during use, the shell 1 and the fixed block 3 have more meshing parts, which causes greater wear on the parts, thus affecting the service life. Therefore, oil holes 4 are provided on the shell 1 and the fixed block 3, and lubricating oil is added to the inside of the fixed block 3 and the shell 1 through the oil holes 4, so that the parts are not easily worn, thereby extending the service life.
