Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spherical simulation gemstone grinding equipment, and particularly relates to a spherical simulation gemstone grinding device and a use method. BACKGROUND

[0002] In the jewelry processing industry, the grinding of spherical simulation gemstones is a crucial step, and the grinding quality directly affects the appearance and value of the final product. Traditional grinding devices usually use fixed grinding discs, and the gemstones are fixed on the grinding device by manual or mechanical methods, and then the grinding operation is performed. However, this traditional method has many shortcomings.

[0003] Firstly, in the grinding process of the traditional grinding device, due to the wear of the grinding disc, the grinding effect will gradually decrease. When the grinding disc is worn to a certain extent, if it is not replaced in time, it will seriously affect the grinding quality, and even may cause scratches or unevenness on the surface of the gemstone. However, in actual operation, since the wear degree of the grinding disc cannot be accurately judged, the grinding disc is often excessively worn without being replaced in time, thereby affecting the grinding efficiency and product quality.

[0004] Secondly, in the grinding process of the traditional grinding device, the grinding force and grinding time need to be controlled manually, which not only increases the operation difficulty, but also easily leads to uneven grinding or over-grinding. In addition, due to the limited contact area between the grinding disc and the gemstone, if the relative position between the grinding disc and the gemstone changes, it will directly affect the grinding effect.

[0005] In addition, when replacing the grinding disc of the traditional grinding device, it is usually necessary to disassemble the entire grinding device or perform tedious adjustment work, which not only increases the operation complexity, but also reduces the grinding efficiency. At the same time, since the replacement times and usage of the grinding disc cannot be accurately recorded, the grinding disc is often used improperly or excessively, thereby further affecting the grinding quality and equipment life. Therefore, we provide a spherical simulation gemstone grinding device and a use method. SUMMARY

[0044] Wherein, with the 10 surface is worn, each time 3 output length will change, when 3 drive 4 and 33 down length and a piece of 10 design thickness is consistent, first explained that 10 can't use again; And at the same time, 33 drive 34 down in the process will let two 32 relative movement, and then let 30 drive 31 from the inner wall of 25 move out; And 35 of the lower end surface will touch 38 and 39 at the same time, 38 let 37 count plus one, and 39 let 3 produce reverse start, and then drive 4 up; At this time, 10 is subjected to the elastic force of 40 and produce three pieces of the same time up; The user will clean up the uppermost piece of 10; Later, start 3 again, 4 drive ball surface simulation gem continue to touch pressure the uppermost 10, so that 10 will move down, because the end of 31 is arc shape design, make 10 move down will extrude and let 31 move, when the end of 31 and 25 align, 31 will be reset again and inserted into the inner wall of 25 under the cooperation of 28, 29 and 30; In this way, it quickly completed the removal of the uppermost 10 and instead; In this way, when 37 count reaches two, at this time can join the new 10 to supplement; Here, 9 and 10 design can be set according to the demand, not limited to set three 10.

[0045] The working principle of the present application is as follows: first, the grinding disc 10 is placed in the circular groove box 9 and fixed by the anti-rotation structure and the limiting mechanism. Specifically, the rectangular through slot two 24 at the center of the grinding disc 10 is aligned with the hollow insertion plate 23 and inserted, and the arc-shaped limiting insertion block 31 is inserted into the limiting insertion slot 25 by moving the moving sleeve block 30; the spherical simulated gem is placed in the holder 4 and adjusted to the appropriate height by the hydraulic cylinder 3. At this time, attention should be paid to keep the holder 4 in a certain hovering state for subsequent operation; before starting the equipment, the holder 4 drives the spherical simulated gem to slowly descend. When the spherical simulated gem contacts the grinding disc 10 and continues to press down, the circular groove box 9 will press down the rectangular insertion rod 16, so that it triggers the start switch 22. At this time, the driving motor 5 starts to rotate the circular groove box 9 and the grinding disc 10 through the shaft rotating rod 6, the insertion rod 8 and the guide sliding structure. The spherical simulated gem is ground with the rotating grinding disc 10 under the fixation of the holder 4; as the grinding proceeds, the grinding disc 10 will gradually wear and thin. When the grinding disc 10 is worn to a certain extent, it can be judged by observing the grinding effect or the replacement times recorded by the counter 37, and the descending length of the holder 4 will increase. At this time, the hollow box 34 will contact and push the two triangular plates 32 to move relatively, thereby driving the arc-shaped limiting insertion block 31 to be pulled out of the limiting insertion slot 25, thereby releasing the fixation of the grinding disc 10. At the same time, the fixed plate 35 will touch the reverse start button 39, so that the hydraulic cylinder 3 is reversely started and drives the holder 4 and the spherical simulated gem to move upwards. At this time, under the action of the spring four 40, the uppermost grinding disc 10 will move upwards and expose the lower grinding disc 10 or the empty position; the user can take out and replace the worn grinding disc 10, or add a new grinding disc 10 and fix it again by the limiting mechanism. Specifically, the new grinding disc 10 is placed in the circular groove box 9 and the rectangular through slot two 24 at the center thereof is aligned with the hollow insertion plate 23 and inserted. Then the arc-shaped limiting insertion block 31 is inserted into the limiting insertion slot 25 again to fix the grinding disc 10 by moving the moving sleeve block 30; the height of the holder 4 and the spherical simulated gem is adjusted again according to the above steps, and the grinding operation is performed again. During the whole grinding process, the replacement times of the grinding disc 10 recorded by the counter 37 and the grinding effect should be continuously monitored to ensure the grinding quality and efficiency; after completing all the grinding tasks, the driving motor 5 and the hydraulic cylinder 3 are turned off, and the power supply is disconnected. Then the grinding debris and impurities on the workbench 1, the fixed frame 2, the circular groove box 9 and other components are cleaned to keep the equipment clean.
