Technical Field

[0001] The utility model relates to the technical field of grinding equipment, and more specifically, the utility model relates to a grinding machine for fine grinding of graphite. Background Art

[0002] A grinding machine is a grinding machine that grinds the surface of a workpiece with a grinding tool coated or embedded with abrasive. It is mainly used for grinding high-precision planes, inner and outer cylindrical surfaces, conical surfaces, spherical surfaces, thread surfaces and other shaped surfaces in workpieces. The surface grinding machine is widely used for single-sided grinding and polishing of various materials such as LED sapphire substrates, optical glass wafers, quartz wafers, silicon wafers, chips, molds, light guide plates, and optical fiber connectors. The grinding machine mainly has functions such as grinding and polishing, crushing and mixing.

[0003] During the process of graphite processing, operators often use corresponding grinding machines to perform grinding operations on graphite. In the actual use of existing grinding machines, although they have basic grinding functions, general grinding machines usually use the method of bolts and nuts to fix the grinding bowl body. Such an installation method not only requires operators to use specific tools for disassembly and assembly, but also the disassembly and assembly steps are relatively cumbersome. This not only reduces the efficiency of operators in disassembling and assembling the grinding bowl body, but also increases the labor intensity of operators. Therefore, it needs to be improved.

A limiting rod 6 is fixedly connected between the rectangular plates 2. The outer surface of the limiting rod 6 is movably sleeved with the interior of the moving block 5. Diagonal rods 7 are hinged on both sides of the moving block 5. The other end of the diagonal rod 7 is hinged with a rectangular block 8. Rectangular grooves 24 are opened on both sides of the top of the fixed frame 1. The outer surface of the rectangular block 8 is movably connected with the interior of the rectangular groove 24. A clamping plate 9 is fixedly connected to the top of the rectangular block 8. A grinding bowl body 10 is movably connected between the clamping plates 9. The bottoms of the clamping plate 9 and the grinding bowl body 10 are movably connected to the top of the fixed frame 1.

[0023] When the first motor 3 starts to operate, it will cause the first threaded rod 4 to rotate, and cause the moving block 5 to move horizontally forward under the limiting action of the limiting rod 6, so that the two rectangular blocks 8 drive the two clamping plates 9 to move horizontally towards each other under the limiting action of the rectangular groove 24, and finally the fixing effect on the grinding bowl body 10 will be realized.

[0024] Among them, a fixing plate 11 is fixedly connected to the rear of the top of the fixed frame 1. A second motor 12 is fixedly connected to the top of the fixing plate 11. A vertical groove 15 is opened on the inner side of the fixing plate 11. The other end of the output shaft of the second motor 12 is fixedly sleeved with a second threaded rod 13.

[0025] When the second motor 12 starts to operate, it will cause the second threaded rod 13 to rotate.

[0026] Among them, the bottom end of the second threaded rod 13 penetrates through the fixing plate 11 and extends to the outside of the fixing plate 11 and is movably sleeved with the top of the fixed frame 1. A connecting plate 14 is threadedly sleeved on the outer surface of the second threaded rod 13. The outer surface of the connecting plate 14 is movably connected with the interior of the vertical groove 15.

[0027] When the second threaded rod 13 rotates, it will cause the connecting plate 14 to move vertically downward under the limiting action of the vertical groove 15.

[0028] Among them, a driving motor 16 is fixedly connected to the top of the connecting plate 14. The other end of the output shaft of the driving motor 16 is fixedly sleeved with a first rotating shaft 17. The other end of the first rotating shaft 17 penetrates through the connecting plate 14 and extends below the connecting plate 14 and is fixedly sleeved with a grinding roller 18.

[0029] When the driving motor 16 starts to operate, it will cause the first rotating shaft 17 to drive the grinding roller 18 to rotate.

[0030] Among them, a power motor 19 is fixedly connected to the top of the connecting plate 14 and is directly in front of the driving motor 16. The other end of the output shaft of the power motor 19 is fixedly sleeved with a second rotating shaft 20.

[0031] When the power motor 19 starts to operate, it will cause the second rotating shaft 20 to rotate.

[0032] Among them, the bottom end of the second rotating shaft 20 penetrates through the connecting plate 14 and extends below the connecting plate 14 and is fixedly sleeved with a gear 21. The outer surface of the gear 21 is meshed and connected with an internal gear ring 22.

[0033] When the second rotating shaft 20 rotates, it will cause the gear 21 to drive the internal gear ring 22 to rotate.

[0034] Among them, the top of the internal gear ring 22 is movably sleeved with the bottom of the connecting plate 14, and the bottom of the internal gear ring 22 is fixedly connected with a scraper 23.

[0035] Due to the design of the scraper 23, it avoids graphite from adhering to the high places on the inner wall of the grinding bowl body 10.

[0036] The working principle and usage process of the present utility model:

[0037] First, place the grinding bowl body 10 filled with graphite on the top of the fixing frame 1. Then start the first motor 3, which will cause the first threaded rod 4 to rotate, and cause the moving block 5 to move horizontally forward under the limiting action of the limiting rod 6. Thus, the two rectangular blocks 8 drive the two clamping plates 9 to move horizontally towards each other under the limiting action of the rectangular groove 24, and finally the fixing effect on the grinding bowl body 10 is achieved, thereby realizing the purpose of facilitating the disassembly and assembly of the grinding bowl body 10, improving the efficiency of the operator in disassembling and assembling the grinding bowl body 10, and reducing the labor intensity of the operator.

[0038] When grinding operation is required after the grinding bowl body 10 is fixed, start the second motor 12, which will cause the second threaded rod 13 to rotate, and cause the connecting plate 14 to move vertically downward under the limiting action of the vertical groove 15. When the bottom of the connecting plate 14 contacts the top of the grinding bowl body 10, start the driving motor 16, so that the first rotating shaft 17 drives the grinding roller 18 to rotate. At this time, the grinding operation will be carried out. When the graphite particles accumulate at the high places on the inner wall of the grinding bowl body 10 and are difficult to grind evenly, at this time, start the power motor 19, which will cause the second rotating shaft 20 to drive the gear 21 to rotate, so that the internal gear ring 22 drives the scraper 23 to rotate at the bottom of the connecting plate 14, thereby realizing the function of scraping off the graphite adhering to the high places on the inner wall of the grinding bowl body 10 and pushing it into the bottom of the grinding bowl body 10, improving the quality of the grinding operation of the device, and avoiding the situation of uneven grinding.
