AI Technical Summary
The existing grinding device cannot continue to grind the section after the rotation direction is changed, and the crossbar occupies a large area, which limits the ability to polish multiple slices at the same time.
A grinding device for rock mineral experiments was designed. The combination of positioning ring and spherical rotating beads was used to make the inner wall of the positioning ring come into contact with the quantitative grinder by rotating the nut, limiting its range of motion, while allowing rotation and grinding, and evenly distributed on the top of the grinding panel, achieving multiple slices at the same time.
The rotation grinding of the quantitative grinder is realized when the grinding device is rotated. Since the positioning ring occupies a small area, it can be evenly distributed on the grinding panel, which facilitates grinding multiple slices at the same time and improves grinding efficiency.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0025] Referring to Figures 1-5, a grinding device for rock and mineral experiments includes a grinding table 1. A driving mechanism is provided inside the grinding table 1. A grinding panel 3 is fixedly connected to the output end of the driving mechanism. A control panel 2 is fixedly connected to the side of the grinding table 1. A splash guard 4 which is cocentric with the grinding panel 3 is fixedly connected to the top of the grinding table 1. The control panel 2 can control the rotation speed of the grinding device.
[0026] The outer surfaces of the grinding panel 3 on both sides above the grinding operation table 1 are fixedly connected with support rods 5, and the outer surfaces of the tops of the support rods 5 are fixedly connected with cross bars 6. The outer surfaces above the cross bars 6 and the grinding panel 3 are fixedly connected with mounting frames 7. The interior of the mounting frame 7 is rotatably connected with a limit gear 12. The interiors of the two sides of the mounting frame 7 are penetrated with limit grooves 8. The interiors of the limit grooves 8 are slidably connected with the limit plates 9. A connecting plate 10 concentric with the limit gear 12 is arranged directly above the limit gear 12. The bottom of the connecting plate 10 is fixedly connected with the limit gear 12. The limiting plate 9 and the mounting frame 7 are threadedly connected with a fixing screw 11, the bottom of the fixing screw 11 is rotatably connected to the top of the connecting plate 10, the interior of the limiting plate 9 is provided with a tooth block meshing with the limiting gear 12, the lower outer surface of the limiting gear 12 is fixedly connected with a connecting rod 13, and the connection between the connecting rod 13 and the limiting gear 12 is rotatably connected to the inside of the cross bar 6. The user can drive the connecting plate 10 to move by rotating the fixing screw 11, thereby driving the limiting plate 9 to move, so that the limiting gear 12 can be limited in position.
[0027] The outer surface of the bottom end of the connecting rod 13 is fixedly connected with a mounting plate 14 with a pentagonal cross-section. Positioning rings 15 that are movably engaged with the inside of the mounting plate 14 are respectively provided in the directions of the five surfaces of the mounting plate 14. A spherical rotating bead 20 is rotatably connected to the inside of the positioning ring 15. The positioning ring 15 is set as an open ring. The open ends of the positioning ring 15 are respectively fixedly connected to the connecting blocks 16. The two ends of the positioning ring 15 are respectively fixedly connected to the connecting blocks 16. One group of connecting blocks 16 are rotatably connected with a positioning screw 17. The positioning screw 17 penetrates and is rotatably connected with a clamping block 18. A nut 19 that is threadedly connected with the positioning screw 17 is provided on the side of the clamping block 18 away from the connecting block 16. The inside of the clamping block 18 is movably engaged with a group of connecting blocks 16 close to the nut 19. Rotating the nut 19 drives the clamping block 18 to drive the connecting block 16 to move toward another group of connecting blocks 16, so that the motion range of the quantitative grinder on the inner wall of the positioning ring 15 is reduced, thereby achieving the purpose of limiting the motion range of the quantitative grinder.
[0028] A positioning block 21 is fixedly connected to the top of the grinding operating table 1, and a plug rod 22 is fixedly connected to the top of the positioning block 21. A fixing block 24 movably engaged with the plug rod 22 is provided on the top of the positioning block 21. A limiting screw 23 is rotatably connected to the interior of the fixing block 24, and the tail end of the limiting screw 23 is threadedly connected to the interior of the plug rod 22. When rotating and grinding, a certain amount of heat will be generated, and paraffin is generally used when the slices are fixed. Paraffin is easy to melt at high temperatures, so coolant needs to be used for cooling. Therefore, the user can place the coolant nozzle on the top of the positioning block 21, and then rotate the limiting screw 23 to drive the fixing block 24 to move downward, thereby limiting the position of the coolant nozzle, so that the coolant nozzle can be close to the grinding range, thereby achieving a better cooling effect.
[0029] In summary: during the application of the utility model, when grinding, the user places the quantitative grinder inside the positioning ring 15, and then rotates the positioning screw 17 so that the block 18 at the tail end of the positioning screw 17 is clamped on the outer surface of the connecting block 16, and then rotates the nut 19 so that the nut 19 drives the block 18 to move toward the other end of the connecting block 16, thereby tightening the positioning ring 15 inward, so that the positioning ring 15 can limit the quantitative grinder, and the interior of the positioning ring 15 is provided with a spherical rotating bead 20 that can reduce friction with the surrounding of the quantitative grinder, and the circumference of the positioning ring 15 is slightly larger than that of the quantitative grinder, so that the positioning ring 15 can limit the quantitative grinder without affecting the self-rotation of the quantitative grinder. At the same time, the area occupied by the positioning ring 15 is relatively small, and multiple groups of positioning rings 15 that limit the movement range of the quantitative grinder can be set on the top of the grinding device. At the same time, since the corresponding tools need to be used when locking the positioning ring 15, when locking the positioning ring 15 on the inner side of the grinding panel 3, the user can first rotate the fixing screw 11 to drive the connecting plate 10 to move upward, and then the connecting plate 10 drives the limiting plate 9 to move upward, so that the limiting gear 12 can drive multiple groups of positioning rings 15 to rotate, so that the positioning ring 15 in the corner rotates directly opposite to the user, which is more convenient for the user to lock the positioning ring 15, and then rotate the fixing screw 11 to limit the position of the limiting gear 12, and finally turn on the grinding device to grind the slices.

Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
