[0031] The various components of the bidirectional linkage rotary deburring device are interconnected, forming the main body of the entire device. This device is an auxiliary deburring device for products, and its power source is pneumatic.

[0032] During assembly, the side plate 23 is screwed onto the upper rear side of the base 21, forming the overall support for the device. The bearing seat 12 is positioned by pins and screws and installed in the middle of the side plate 23. The main shaft 13 is mounted in the bearing seat 12 in the middle position. The upper bearing 11 and lower bearing 17 are respectively installed at the upper and lower ends of the main shaft 13 and are engaged in the slots at the upper and lower ends of the bearing seat 12. The bushing 18 is fitted onto the lower end of the main shaft 13, with its upper plane coinciding with the lower surface of the lower bearing 17. The gear 19 is installed at the bottom of the main shaft 13, with its upper plane coinciding with the bottom of the bushing 18. The pressure block 20 is screwed onto the bottom plane of the main shaft 13 for fixing the gear 19. The slider 22 is located on the side of the gear 19 and is positioned by pins and screws on the lower end of the side plate 23. The bottom of the rack 14 passes through the guide groove at the upper end of the slider 22. After engaging with the gear 19, its rear end is connected to the telescopic rod at the front end of the cylinder 16 by screws. Cylinder 16 is mounted on fixing block 15 with screws, and fixing block 15 is fixed to the side of side plate 23. After the above assembly is completed, when the telescopic rod on cylinder 16 extends and retracts, the main shaft 13 will rotate back and forth under the conversion action of rack 14 and gear 19. The center slot of tray 4 is inserted into the upper end of main shaft 13, and its bottom plane coincides with the middle upper surface of upper bearing 11. Bushing 10 is inserted into the upper part of tray 4 and connected to the upper end of main shaft 13 with screws to complete the locking between tray 4 and main shaft 13.

Cylinder 8 is mounted on the upper part of support block 9 with screws. Support block 9 is mounted on the upper surface of tray 4 and secured with screws. After the above assembly is completed, the telescopic rod on cylinder 8 moves back and forth, causing the second slider 7 to open and close relative to the first slider 6. The first cutting blade 3A and the second cutting blade 3B are respectively installed in the corresponding positioning slots at the upper ends of the first slider 6 and the second slider 7 and secured with screws. Positioning block 2 is installed in the uppermost positioning groove of side plate 23 and secured with screws. Workpiece 1 is placed in the positioning groove on the upper part of positioning block 2. At this time, the rod of workpiece 1 and the spindle 13 are on the same axis. Air valve switch 24 is mounted on the upper rear side of side plate 23 with screws, and all air pipes are installed and connected. Thus, the entire assembly of the bidirectional linkage rotary deburring device is completed.

[0033] After the device is installed and debugged, it is in the initial zero position. At this time, the telescopic rods on cylinders 8 and 16 are in the retracted state. The second slider 7 is in the open state relative to the first slider 6, and a gap is formed between the first cutter 3A and the second cutter 3B. The workpiece 1 is placed into the positioning groove on the positioning block 2, and the rod of the workpiece 1 (preferably the main shaft of the workpiece 1) passes through the center position of the first cutter 3A and the second cutter 3B. At this time, the upper planes of the first cutter 3A and the second cutter 3B are attached to the root of the main shaft of the workpiece 1, and the main shaft of the workpiece 1 is concentric with the main shaft 13. The air valve switch is turned on, the telescopic rod of cylinder 8 is pushed out, and the second slider 7 is driven forward. The first cutter 3A and the second cutter 3B on the first slider 6 and the second slider 7 are stuck to the burrs at the root of the main shaft of the workpiece 1. At the same time, the telescopic rod of cylinder 16 is also pushed out, and the rack 14 is driven forward. Under the action of the rack 14, the gear 19 drives the first cutter 3A and the second cutter 3B on the main shaft 17 to rotate. During the rotation process, burrs around the spindle of workpiece 1 are removed. The air valve switch is then activated again, causing the second slider 7 to open the cutter 3, and the cylinder 16 to retract the rack 14. After completing these operations, workpiece 1 is removed. This completes one full operation.

[0034] In the aforementioned bidirectional linkage rotary deburring device, a fixed frame provides stable support and a working benchmark for the overall structure, ensuring equipment stability and processing accuracy. The drive unit drives the spindle to rotate stably, causing the cutter fixing and control device at the top of the spindle to rotate as a whole, providing reliable rotational power for the rotary deburring of rods. The cutter fixing and control device, driven by a cylinder, moves the second slider relative to the first slider, achieving symmetrical opening and closing adjustment of the first and second cutters. This adapts to the processing needs of workpieces of different specifications, precisely fitting the outer circumference of the rod to complete the rotary deburring. Simultaneously, the top positioning block fixes the workpiece through a positioning groove and uses through holes to limit the position of the workpiece rod, ensuring the rod accurately extends between the two cutters, guaranteeing coaxiality and alignment accuracy. This device, through the coordinated linkage of its various structures, replaces the traditional manual deburring method, simplifies processing procedures, effectively improves the efficiency of burr removal from rods, ensures a uniform and regular surface curvature after processing, reduces manual processing costs and errors, and is suitable for the standardized batch processing of precision rod-type parts.
