[0033] It should be noted that the present embodiment is not limited to the above-mentioned electric telescopic rod 25 to adjust the position of the outer cylinder 26, and a linear motor or a cylinder may also be used instead, which are not listed here one by one.

[0034] In actual application, the cylindrical part is placed in the inner cylinder 27, and the outer cylinder 26 and the cylindrical part are driven to move toward the clamping table 41 by controlling the electric telescopic rod 25 to retract.

[0038] When the cylindrical part is placed on the inner side of the inner cylinder 27, the electric telescopic rod 25 is controlled to be energized and contracted, so that the outer cylinder 26 can be driven to move toward the clamping seat 40. Under the meshing action between the driving gear 31 and the rack 30, the driving gear 31 and the winding disk 38 can be driven to rotate.

One end of the sliding rod 50 is connected to the positioning gear 39, and the other end is slidably inserted in the matching tube 51.

[0042] In actual application, by rotating the handle 52, the adjusting gear 39 is driven to rotate.

[0047] How this application works:

[0048] By placing the tool in the tool groove and rotating the clamping screw 23, the clamping plate 14 is driven to move, so that the tool is clamped and fixed. When the cylindrical part is placed on the inner side of the inner cylinder 27, the electric telescopic rod 25 is controlled to be energized and contracted, so that the outer cylinder 26 can be driven to move toward the clamping seat 40. Under the meshing action between the driving gear 31 and the rack 30, the driving gear 31 and the winding disk 38 can be driven to rotate. The rotation of the winding disk 38 can release the winding connection belt, so that under the action of the elastic restoring force between the piston 35 and the hollow tube 33, the piston 35 moves along the hollow tube 33, so that the air in the hollow tube 33 is squeezed into the airbag 34, so that the volume of the airbag 34 increases. The increase in the volume of the airbag 34 can be with the inner side of the inner cylinder 27 The cylindrical part of the inner cylinder 27 comes into conflict with it, so that the cylindrical part is moved closer to the center of the circle of the inner cylinder 27, thereby realizing the auxiliary positioning of the cylindrical part. Finally, the cylindrical part can be inserted into the clamping table 41, and the adjusting gear 39 is driven to rotate by rotating the turning handle 52. Under the threaded cooperation between the adjusting gear 39 and the threaded seat 46, the adjusting gear 39 can be driven to rotate and move. Under the sliding cooperation between the slide rod 50 and the matching tube 51, the adjusting gear 39 can be driven to rotate synchronously, thereby driving the adjusting disk 48 to rotate. Under the sliding cooperation between the adjusting ramp 49 and the movable wheel 44, the moving block 45 can be driven to move along the guide groove 43, so that the clamping arms 42 move toward each other, thereby realizing the clamping and fixing of the positioned cylindrical part. After completing the clamping and fixing work of the cylindrical part, the control console 3 controls the adjustment screw 5 to rotate so that the movable seat 7 moves to the processing position of the cylindrical part, and the control console 3 controls the driving motor 15 to be powered on and rotated, driving the active wheel 16 to rotate, and under the meshing action between the active wheel 16 and the driven wheel 17, the driven wheel 17 and the processing seat 11 can be driven to rotate, thereby driving the tool to rotate, and the cylindrical part can be clamped and fixed by the tool, and when the processing seat 11 rotates, the protective seat 18 and the No. 1 magnetic block 19 can be driven to rotate, and under the meshing action between the No. 1 magnetic block 19 and the No. 2 magnetic block 21, the driven disk 20 and the fan blades 22 are driven to rotate, and then the chips generated during the cutting process are sucked into the dust storage box 6, and there is no need for the staff to manually handle impurities on the surface of the machine tool.
