[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. It should also be noted that, for ease of description, only the parts related to the utility model are shown in the drawings.

[0032] Example: Reference Figure 1-4 The device for polishing Juque stone handicrafts shown in the figure comprises a pool 1, two side plates 9 are fixed on the upper surface of the pool 1, a top plate 10 is fixed on the top of the two side plates 9, a polisher 11 is movably connected to the lower surface of the top plate 10, a water outlet pipe 6 is fixed through the top of the pool 1, and a drain pipe 5 is fixedly connected to the inner bottom of the pool 1, a column 2 is fixed on the inner bottom surface of the pool 1, a polishing table 3 is rotatably connected to the top of the column 2, and an edge grinding component 8 is installed on the inner side of the pool 1;

[0033] The edge grinding assembly 8 includes a movable plate 801 and two load-bearing rods 813. One end of the load-bearing rod 813 is fixed to the inner side of the pool 1, and the other end of the load-bearing rod 813 slides through the movable plate 801. Two springs 814 are fixed between the pool 1 and the movable plate 801. A reciprocating plate 809 is slidably matched on the upper surface of the movable plate 801. A grinding plate 810 is fixed on one side of the reciprocating plate 809. An arc groove 816 is provided on one side of the grinding plate 810. Sandpaper 820 is fixed on the wall of the arc groove 816. Valves 7 are installed on the drain pipe 5 and the outlet pipe 6, a rubber pad 4 is fixed on the upper surface of the grinding table 3, and the upper surface of the rubber pad 4 is provided with anti-slip grooves, mounting grooves 815 are opened at both ends of the grinding plate 810, and mounting plates 817 are adapted in the mounting grooves 815. The grinding plate 810 and the mounting plate 817 are fixedly connected by fastening bolts 818, and a side plate 819 for clamping the end of the sandpaper 820 is fixed on the inner side of the mounting plate 817, and a grinding disc is provided at the output end of the grinder 11.

[0034] When using the Juque stone handicraft grinding device, the cut stone is first moved to the upper surface of the grinding table 3. At this time, the operator can open the valve 7 on the water outlet pipe 6, spray clean water on the stone through the water outlet pipe 6, and then start the grinder 11. The operator holds the grip of the grinder 11 with one hand and pulls it downward. The square column 18 slides downward in the square tube 17, so that the grinding disc on the grinder 11 contacts the surface of the stone and grinds the stone. The operator can drive the grinder 11 to move to any position above the stone to achieve rapid polishing of the stone surface. During this period, the operator controls the stone with the other hand to prevent the stone from rotating during the grinding process.

[0035] When the upper and lower surfaces of the stone are polished, the grinder 11 is turned off and the pulling force on the grinder 11 is removed. The square column 18 will slide into the square tube 17, driving the grinder 11 to automatically rise. Then the reciprocating plate 809 is controlled to slide back and forth longitudinally on the surface of the movable plate 801, thereby driving the sandpaper 820 to slide back and forth. At this time, the grinding table 3 is slowly rotated, and the stone on it is driven to rotate. The edge of the stone enters the arc groove 816. The reciprocating sandpaper 820 wraps the edge of the stone with a certain arc, quickly polishes off the edges of the stone and forms a uniform arc surface. When the edge of the stone squeezes the grinding plate 810, one end of the load-bearing rod 813 slides into the movable plate 801, and the movable plate 801 squeezes the spring 814. The spring 814 shrinks and deforms due to the force, which can adjust the squeezing force of the stone on the grinding plate 810 to avoid the stone edge from squeezing the arc groove 816. The problem of excessive squeezing of the arc groove 816 causing the sandpaper 820 to be damaged and increasing the load of the servo motor 802 can be solved. When the sandpaper 820 needs to be replaced, it is only necessary to screw the fastening bolts 818 to remove the mounting plate 817 from the mounting groove 815. At this time, the sandpaper 820 can be replaced. In the process of installing the two mounting plates 817, the two mounting plates 817 are symmetrically arranged relative to the grinding plate 810, and the two side plates 819 will squeeze the two ends of the sandpaper 820, so that the sandpaper 820 is tightly attached to the groove wall of the arc groove 816. By rotating the grinding table 3, the stone can be easily rotated, so that the edge of the stone can be quickly polished and regularized. The waste liquid formed by grinding is stored in the pool 1. By opening the valve 7 on the drain pipe 5, the waste liquid and sediment in the pool 1 can be discharged. The setting of the rubber pad 4 plays a role in preventing the stone from slipping.

[0036] In order to enable the square column 18 to automatically drive the grinder 11 to rise and move when not affected by external force, the operator can drive the grinder 11 to move to any position above the stone. In this embodiment, two horizontal sliding bars 12 are fixed to the lower surface of the top plate 10, and a first sliding seat 13 is slidably sleeved on the horizontal sliding bar 12. An adjusting frame 14 is fixed to the lower surface of the first sliding seat 13, and a second sliding seat 16 is slidably fitted in the adjusting frame 14. A vertically liftable grinder 11 is fixed to the lower surface of the second sliding seat 16. Two longitudinal sliding bars 15 are fixed to the inner side of the adjusting frame 14, and the second sliding seat 16 is slidably sleeved on the longitudinal sliding bars 15. A square cylinder 17 is fixed to the lower surface of the second sliding seat 16, and a square column 18 is slidably fitted in the square cylinder 17. The grinder 11 is fixed to the bottom end of the square column 18, and a tension spring 19 is fixed between the groove top of the square cylinder 17 and the top end of the square column 18. Since the first slide 13 slides in cooperation with the transverse slide bar 12, and the longitudinal slide bar 15 slides in cooperation with the second slide 16, the operator can drive the grinder 11 to move to any position above the stone. When the square column 18 moves downward in the square tube 17 due to external force, the tension spring 19 will be stretched. When the external force on the square column 18 is removed, the square column 18 will be pulled up under the action of the elastic restoring force of the tension spring 19, and drive the grinder 11 to rise to the initial position.

[0037] In order to enable the movable plate 801 to slide more stably with the load-bearing rod 813, further, in the present embodiment, two circular grooves 812 are opened on one side of the movable plate 801, and one end of the two load-bearing rods 813 slides in the two circular grooves 812 respectively, and the spring 814 surrounds the outside of the load-bearing rod 813, which can prevent the spring 814 from bending and deforming during compression.

[0038] In order to control the reciprocating plate 809 to slide back and forth longitudinally on the surface of the movable plate 801, in this embodiment, a servo motor 802 is fixedly installed on the upper surface of the movable plate 801, an eccentric plate 803 is fixedly installed on the rotating shaft of the servo motor 802, a driving rod 804 is fixed on one end of the side of the eccentric plate 803, a vertical groove 811 is opened on one side of the reciprocating plate 809, and the driving rod 804 slides in the vertical groove 811. After the servo motor 802 is started, it drives the eccentric plate 803 to rotate, and at this time the eccentric plate 803 will draw a circle, and the driving rod 804 slides up and down in the vertical groove 811 and drives the reciprocating plate 809 to move back and forth.

[0039] In order to enable the reciprocating plate 809 to slide stably on the surface of the movable plate 801, further, in the present embodiment, a slide groove 805 is provided on the upper surface of the movable plate 801, and a slider 807 is fixed to the bottom end of the reciprocating plate 809. The slider 807 slides in the slide groove 805. Limiting grooves 806 are provided on both walls of the slide groove 805. Limiting plates 808 are fixed on both side surfaces of the slider 807. The limiting plates 808 slide in the limiting grooves 806. The setting of the limiting plates 808 and the limiting grooves 806 restricts the slider 807 in the slide groove 805, so that the slider 807 slides stably in the slide groove 805, thereby driving the reciprocating plate 809 to slide stably on the surface of the movable plate 801.
