[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a device for removing edge burrs in sheet metal part processing, including a bearing plate 1. A through groove 2 is opened on the bearing plate 1. The inner surface of the through groove 2 is rotatably connected to a horizontal lead screw 3 and extends out at one end. The outer surface of the horizontal lead screw 3 is threadedly connected to an internal thread sleeve 4. The top of the internal thread sleeve 4 is fixedly connected to a main housing 5. The inside of the main housing 5 is rotatably connected to a vertical lead screw 6 and extends out at one end. The outer surface of the vertical lead screw 6 is threadedly connected to an internal thread block 7. One side of the internal thread block 7 is fixedly connected to a limit rod 8. The outer surface of the limit rod 8 is movably sleeved with a limit sleeve 9. The outer surface of the limit sleeve 9 is fixedly embedded on one side of the main housing 5. The end of the limit rod 8 away from the internal thread block 7 is fixedly connected to a scraper 10. Rotating the thread will drive the internal thread block 7. Since the limit rod 8 can only move along the inside of the limit sleeve 9, rotating the thread can drive the limit rod 8 to extend outwards along the inside of the limit sleeve 9.

[0026] As Figures 1 to 5 shown, the end of the vertical lead screw 6 extending out is fixedly connected to a rotating block 11. The inside of the rotating block 11 is movably embedded with a rocker 12. Both ends of the rocker 12 are fixedly connected to anti - detachment ball heads 13. The anti - detachment ball heads 13 at both ends of the rocker 12 can prevent the rocker 12 from falling off.

[0027] As Figures 1 to 5 shown, both sides of the internal thread sleeve 4 are fixedly connected to limit plates 14. Both sides of the inner surface of the through groove 2 are provided with limit grooves 15. The outer surface of the limit plate 14 is arranged inside the limit groove 15. Rotating the thread will drive the internal thread sleeve 4. The limit plate 14 can only move along the opening direction of the limit groove 15.

[0028] As Figures 1 to 5As shown, two L-shaped plates 16 are fixedly connected to one side of the bearing plate 1. A motor 17 is fixedly connected to the inner sides of the two L-shaped plates 16. The output end of the motor 17 is fixedly connected to one end of the transverse lead screw 3 extending out. After the motor 17 is powered on, it will drive the transverse lead screw 3 to rotate inside the through groove 2.

[0029] As Figures 1 to 5 shown, a plurality of legs 18 are fixedly connected to the bottom of the bearing plate 1. A workbench 19 is fixedly connected to the top of the bearing plate 1. The legs 18 at the bottom of the device play a role in fixedly supporting the entire device.

[0030] As Figures 1 to 5 shown, two fixing rods 20 are fixedly connected to the top of the bearing plate 1. A fixing plate 21 is fixedly connected to the tops of the two fixing rods 20. The fixing plate 21 is connected above the bearing plate 1 through the two fixing rods 20.

[0031] As Figures 1 to 5 shown, an internally threaded ring 22 is rotatably connected to the inside of the fixing plate 21. A plurality of force application rods 23 are fixedly connected to the outer surface of the internally threaded ring 22. A threaded rod 24 is threadedly connected to the inner surface of the internally threaded ring 22. The internally threaded ring 22 is driven to rotate inside the fixing plate 21 through the force application rods 23.

[0032] As Figures 1 to 5 shown, a lower pressing plate 25 is fixedly connected to the bottom of the threaded rod 24. Positioning sleeves 26 are fixedly connected to both sides of the lower pressing plate 25. The inner surfaces of the positioning sleeves 26 are movably sleeved on the outer surfaces of the fixing rods 20. Because the positioning sleeves 26 on both sides of the lower pressing plate 25 can only move along the axial direction of the fixing rods 20, rotating the thread can make the lower pressing plate 25 move downward along the axial direction of the fixing rods 20.

[0033] Working principle: First, place the sheet metal part to be deburred on the workbench 19. Then, drive the internal thread ring 22 to rotate inside the fixed plate 21 through the force application rod 23. The rotating thread will drive the threaded rod 24. Since the positioning sleeves 26 on both sides of the lower pressure plate 25 can only move along the axis direction of the fixed rod 20, the rotating thread can make the lower pressure plate 25 move downward along the axis direction of the fixed rod 20 and press and fix the workpiece below. Then, adjust the distance between the scraper 10 and the workpiece according to the size of the workpiece. Drive the longitudinal lead screw 6 to rotate inside the main machine housing 5 through the rocker 12 and the rotating block 11. The anti-detachment ball heads 13 at both ends of the rocker 12 can prevent the rocker 12 from detaching. The rotating thread will drive the internal thread block 7. The limiting rod 8 can only move inside the limiting sleeve 9. So the rotating thread can drive the limiting rod 8 to extend outward inside the limiting sleeve 9 and make the scraper 10 contact the edge of the workpiece. Finally, start the external power supply of the motor 17. The model of the motor 17 is: DOY106, rated power: 750W. The motor 17 is fixed on one side of the bearing plate 1 through the L-shaped plate 16. After the motor 17 is powered on, it will drive the transverse lead screw 3 to rotate inside the through groove 2. The rotating thread will drive the internal thread sleeve 4. The limiting plate 14 can only move along the opening direction of the limiting groove 15. So the rotating thread can drive the internal thread sleeve 4 to move along the opening direction of the limiting groove 15 and make the scraper 10 move to remove the burrs on the outside of the workpiece at the same time. The legs 18 at the bottom of the device play a role in fixing and supporting the whole device.

[0034] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
