When the screw sleeve needs to be deburred, the cylinder 3 is started, and the action end of the cylinder 3 pushes the mounting bracket 4 to move downward, so that the wire roller 7 is close to the embedded screw sleeve. The downward movement of the mounting bracket 4 will drive the support rod 8 to move downward, so that the electrode plate 9 also moves downward. When the wire roller 7 contacts the embedded screw sleeve, continuing to press down will compress the spring 13, and the limit block 11 moves upward, so that the electric sheet 12 and the electrode plate 9 change from separation to tangential contact, and an electrical signal will be generated and transmitted to the control panel 33. After receiving the signal, the control panel 33 controls the drive motor 5 to start, and the drive motor 5 drives the rotating shaft 6 to rotate, thereby rotating the wire roller 7 to deburr the embedded screw sleeve, thereby realizing the automatic control of the drive motor 5, improving the deburring efficiency of the screw sleeve, and reducing energy consumption.

[0024] See also Figure 1-4As shown, a groove 14 is provided inside the workbench 1, a servo motor 15 is installed on the inner wall of the bottom side of the groove 14, a gear 16 is installed on the output end of the servo motor 15, two guide rods 17 are symmetrically installed between the two sides of the groove 14, a rack 18 is installed on the outer wall of one end of the guide rod 17, the racks 18 are meshed with the gear 16, a moving block 19 is installed on the top side of the rack 18, a slider 20 is installed on the top side of the moving block 19, two sliders 20 are symmetrically provided inside the top side of the workbench 1, the sliders 20 are respectively slidably installed inside the slide groove 21, a fixed plate 22 is installed on the top side of the slider 20, a rotating shaft 23 is rotatably installed inside the fixed plate 22, and a conical block 24 is installed on one end of the rotating shaft 23. A No. 1 motor 25 is installed on one side of the fixed plate 22; when working, in the production process of the embedded screw sleeve, it is necessary to deburr its outer surface. In order to improve the stability during operation, it needs to be fixed. First, the screw sleeve to be processed is placed on the top side of the support plate 27, and the servo motor 15 is started to drive the gear 16 to rotate, and then simultaneously drive the two racks 18 to move in opposite or same directions along the guide rod 17. The movement of the rack 18 will drive the moving block 19 to move, so that the slider 20 drives the conical block 24 to slide in the slide groove 21, so that the conical block 24 can extend into the screw sleeve to fix the screw sleeve, and start the No. 1 motor 25. The No. 1 motor 25 drives the rotating shaft 23 to rotate, and then the conical block 24 and the screw sleeve rotate, thereby realizing a full range of deburring operations on the outer surface of the screw sleeve.

[0025] See also Figure 1-4 As shown, a straight pipe 26 is installed at the center of the top side of the workbench 1, and a support plate 27 is connected to the top side of the straight pipe 26.

A dust collecting box 30 is installed on one side of the workbench 1. A filter plate 31 is installed inside the dust collecting box 30. A fan 32 is installed inside one side of the bottom end of the dust collecting box 30. During operation, when the wire roller deburrs the workpiece, the friction with the workpiece surface will cause the burrs on the workpiece surface to be worn away. The dust and debris generated during the deburring process will be scraped off, which will produce some impurities such as debris and dust. The fan 32 is started, and the suction force generated causes the dust and debris generated during the deburring process to be sucked into the inside of the support plate 27 through the dust suction hole 28. The dust and debris enter the dust suction pipe 29 along the straight pipe 26 and are then sucked into the dust collecting box 30 through the dust suction pipe 29. The dust and debris will be blocked and filtered by the filter plate 31 and remain in the dust collecting box 30. The filtered air is discharged from the dust collecting box 30 through the fan 32, thereby realizing the collection and cleaning of dust and debris generated during the operation and keeping the working environment clean.

[0026] Working principle: first, place the screw sleeve to be processed on the top side of the support plate 27, start the servo motor 15, drive the gear 16 to rotate, and then simultaneously drive the two racks 18 to move in opposite or same directions along the guide rod 17. The movement of the rack 18 will drive the moving block 19 to move, so that the slider 20 drives the conical block 24 to slide in the slide groove 21, so that the conical block 24 can extend into the screw sleeve to fix the screw sleeve, start the No. 1 motor 25, and the No. 1 motor 25 drives the rotating shaft 23 to rotate, thereby rotating the conical block 24 and the screw sleeve, realizing a full range of deburring operations on the outer surface of the screw sleeve;

[0027] When it is necessary to deburr the screw sleeve, the cylinder 3 is started, and the active end of the cylinder 3 pushes the mounting bracket 4 to move downward, so that the wire roller 7 is close to the embedded screw sleeve. The downward movement of the mounting bracket 4 will drive the support rod 8 to move downward, so that the electrode plate 9 also moves downward. When the wire roller 7 contacts the embedded screw sleeve, continuing to press down will compress the spring 13, and the limit block 11 moves upward, so that the electric sheet 12 and the electrode plate 9 are changed from separation to tangential contact, which will generate an electrical signal and transmit it to the control panel 33. After receiving the signal, the control panel 33 controls the drive motor 5 to start, and the drive motor 5 drives the rotating shaft 6 to rotate, thereby causing the wire roller 7 to rotate to deburr the embedded screw sleeve, thereby realizing the automatic control of the drive motor 5, improving the deburring efficiency of the screw sleeve, and reducing energy consumption.

[0028] When the fan 32 is started, the suction force generated causes the dust and debris generated during the deburring process to be sucked into the support plate 27 through the dust suction hole 28. The dust and debris enter the dust suction pipe 29 along the straight pipe 26 and are then sucked into the dust collection box 30 through the dust suction pipe 29. The dust and debris will be blocked and filtered by the filter plate 31 and remain in the dust collection box 30. The filtered air is discharged from the dust collection box 30 through the fan 32, thereby collecting and cleaning the dust and debris generated during the operation and keeping the working environment clean.
