[0024] like Figures 1-7The diagram illustrates a power fitting grinding device according to an embodiment of this disclosure. It includes a machine base 1, with a top frame 2 fixedly connected to the top of the machine base 1. The device also includes a conveyor frame 3, limiting rods 4, a bottom surface grinding mechanism, and a top surface grinding mechanism. Protective shells are fixedly connected to both the machine base 1 and the top frame 2. The conveyor frame 3 is mounted on the top of the machine base 1 via a lifting mechanism, which is used to drive the conveyor frame 3 for height adjustment. Two limiting rods 4 are provided, and are mounted on the conveyor frame 3 via a swing mechanism, which drives the two limiting rods 4 to swing relative to each other. The bottom surface grinding mechanism is set inside the conveyor frame 3 and is used to grind the bottom surface of the plate-shaped hardware. There are two top surface grinding mechanisms, both of which are set inside the top frame 2 and are used to grind the top surface of the plate-shaped hardware. Through the setting of the conveyor frame 3, the limiting rod 4, the swing mechanism, the bottom surface grinding mechanism and the top surface grinding mechanism, the plate-shaped hardware can be intercepted between the first grinding belt 18 and the second grinding belt 23, so that the plate-shaped hardware can be ground on both sides. Usually, the first grinding belt 18 has a conveying function, which saves time and effort and improves the grinding efficiency of the plate-shaped hardware.

[0025] The lifting mechanism includes: a drive screw 5, a rotating gear 6, a drive gear 7, a first motor 8, and a guide assembly. The top end of the drive screw 5 is fixedly connected to the bottom end of the conveyor frame 3. A through hole is provided on the machine base 1, and the bottom end of the drive screw 5 passes through the through hole and extends into the machine base 1. The rotating gear 6 is rotatably connected to the through hole and has a threaded hole. The drive screw 5 is threaded into the threaded hole. The drive gear 7 is rotatably connected to the machine base 1 and meshes with the rotating gear 6. The first motor 8 is installed inside the machine base 1, and the output end of the first motor 8 is fixedly connected to the drive gear 7. The guide assembly is located inside the top frame 2 and is used to support the lifting and lowering movement of the conveyor frame 3. The component includes: guide rods 28 and guide blocks 29.

Each guide rod 28 is slidably connected to a guide block 29, and all guide blocks 29 are fixedly connected to the conveyor frame 3. The first motor 8 drives the drive gear 7 to rotate. When the drive gear 7 rotates, it drives the rotating gear 6 to rotate. When the rotating gear 6 rotates, the screw hole on the rotating gear 6 rotates on the drive screw 5, thereby driving the drive screw 5 and the conveyor frame 3 to rise or fall. When the conveyor frame 3 rises or falls, it drives the guide blocks 29 to slide on the guide rods 28, thereby increasing the stability of the conveyor frame 3 when sliding.

[0026] The swing mechanism includes: a base plate 9, a rotating rod 10, a transmission gear 11, and a drive assembly. Two base plates 9 are provided, fixedly connected to both sides of the conveyor frame 3. A rotating rod 10 is rotatably connected to the top of each base plate 9. Two limit rods 4 are fixedly connected to the tops of the two rotating rods 10. A transmission gear 11 is fixedly connected to each of the two rotating rods 10. The drive assembly is located inside the conveyor frame 3 and is used to drive the two transmission gears 11 to swing relative to each other. The drive assembly includes: a sliding rod 12, a toothed plate 13, a drive block 14, a moving screw 15, and a second motor 16. A sliding groove is provided on the conveyor frame 3, and the sliding rod 12 is slidably connected within the groove. Two toothed plates 13 are provided, fixedly connected to both ends of the sliding rod 12, and meshing with the two transmission gears 11. The drive block 14 is fixedly connected to the bottom end of the sliding rod 12. The moving screw 15 is rotatably connected inside the conveyor frame 3, and a screw hole is provided on the drive block 14. The screw 15 is threaded into the screw hole. The second motor 16 is installed in the conveyor frame 3. The output end of the second motor 16 is fixedly connected to one end of the moving screw 15. Two stabilizing plates 27 are fixedly connected in the conveyor frame 3. The two ends of the moving screw 15 are rotatably connected to the two stabilizing plates 27 respectively. The second motor 16 is installed on one of the stabilizing plates 27. The output end of the second motor 16 passes through the stabilizing plate 27 and is fixedly connected to one end of the moving screw 15. The second motor 16 drives the moving screw 15 to rotate. When the moving screw 15 rotates, it drives the drive block 14 and the slide rod 12 to move. When the slide rod 12 moves in the slide groove, it drives the two toothed plates 13 to move synchronously. Since the two transmission gears 11 mesh with the two toothed plates 13 respectively, when the toothed plates 13 move, they drive the two transmission gears 11 and the two rotating rods 10 to rotate relative to each other, thereby driving the two limit rods 4 to swing relative to each other, thus intercepting the plate-shaped hardware on the first grinding belt 18 during grinding.

[0027] The bottom surface grinding mechanism includes: a grinding shaft 17, a first grinding belt 18, and a third motor 19. There are two grinding shafts 17, both of which are rotatably connected to the conveyor frame 3. The first grinding belt 18 is driven between the two grinding shafts 17. The third motor 19 is installed on one side of the conveyor frame 3. The output end of the third motor 19 passes through the conveyor frame 3 and is fixedly connected to one of the grinding shafts 17. The third motor 19 drives one of the grinding shafts 17 to rotate. The first grinding belt 18 is driven between the two grinding shafts 17, thereby driving the first grinding belt 18 to grind the bottom surface of the plate-shaped hardware.

[0028] The top surface grinding mechanism includes: a support plate 20, a rotating shaft 21, a slider 22, a second grinding belt 23, a fourth motor 24, and a tensioning assembly. The support plate 20 has a groove, and the slider 22 is slidably connected within the groove. There are two support plates 20, both fixedly connected within the top frame 2. There are two rotating shafts 21, one with both ends rotatably connected to the two support plates 20 respectively. There are two sliders 22, each slidably connected to one of the two support plates 20. The other rotating shaft 21 has both ends rotatably connected to the two sliders 22 respectively. The second grinding belt 23 is driven between the two rotating shafts 21. The fourth motor 24 is mounted on one of the support plates 20, and its output end passes through the support plate. Plate 20 is fixedly connected to one end of rotating shaft 21. Tensioning assembly is set on top frame 2 for pulling two sliders 22 to move. Tensioning assembly includes: connecting frame 25 and first electric cylinder 26. Connecting frame 25 is fixedly connected to the top of two sliders 22. First electric cylinder 26 is installed on the top of top frame 2. The output end of first electric cylinder 26 passes through top frame 2 and is fixedly connected to connecting frame 25. First electric cylinder 26 drives connecting frame 25 to rise. When connecting frame 25 rises, it drives two sliders 22 and top rotating shaft 21 to rise, thereby tensioning second grinding belt 23 driven between two rotating shafts 21. Then, fourth motor 24 drives bottom rotating shaft 21 to rotate, thereby driving second grinding belt 23 to grind the top surface of plate-shaped hardware.

[0029] Working principle: When grinding plate-shaped hardware is required, the plate-shaped hardware is placed on the first grinding belt 18. The first grinding belt 18 transmits power between the two grinding shafts 17, slowly conveying the plate-shaped hardware. Then, the second motor 16 drives the moving screw 15 to rotate. When the moving screw 15 rotates, it moves the drive block 14 and the sliding rod 12. As the sliding rod 12 moves within the groove, it drives the two toothed plates 13 to move synchronously. Since the two transmission gears 11 mesh with the two toothed plates 13 respectively, the movement of the toothed plates 13 drives the two transmission gears 11 and the two rotating rods 10 to rotate relative to each other, thereby causing the two limit rods 4 to swing relative to each other, thus grinding the plate-shaped hardware on the first grinding belt 18. During grinding, the plate-shaped fitting is slowly intercepted. The first electric cylinder 26 drives the connecting frame 25 to rise. When the connecting frame 25 rises, it drives the two sliders 22 and the top rotating shaft 21 to rise, thereby tightening the second grinding belt 23 between the two rotating shafts 21. Then, the fourth motor 24 drives the bottom rotating shaft 21 to rotate, thereby driving the second grinding belt 23 to grind the top surface of the plate-shaped fitting. During the interception of the plate-shaped fitting by the limit rod 4, the limit rod 4 maintains a certain speed of swing. At this time, the plate-shaped fitting can be both ground and transported. When the two limit rods 4 are fully open, the plate-shaped fitting is completely transported by the first grinding belt 18. Subsequent plate-shaped fittings to be ground can be continuously ground on both sides by following the above steps.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
