Description

Technical Field

[0001] The invention relates to the technical field of spherical simulated gem grinding equipment, and in particular to a spherical simulated gem grinding device and a use method thereof. Background Art

[0002] In the jewelry processing industry, the grinding of spherical simulated gemstones is a crucial link, and its 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 means before the grinding operation. However, this traditional method has many shortcomings.

[0003] First, in the process of grinding, the grinding effect of the traditional grinding device will gradually decrease due to the wear of the grinding disc. 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 may even cause scratches or unevenness on the surface of the gemstone. However, in actual operation, since it is impossible to accurately judge the wear degree of the grinding disc, the grinding disc is often over-worn and not replaced in time, which affects the grinding efficiency and product quality.

[0004] Secondly, the traditional grinding device needs to manually control the grinding force and grinding time during the grinding process, which not only increases the difficulty of operation, but also easily leads to uneven grinding or over-grinding. In addition, since the contact area between the grinding disc and the gemstone is limited, 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 a traditional grinding device, it is usually necessary to disassemble the entire grinding device or perform tedious adjustments, which not only increases the complexity of the operation, but also reduces the grinding efficiency. At the same time, since it is impossible to accurately record the number of replacements and usage of the grinding disc, the grinding disc is often used improperly or excessively, which further affects the grinding quality and equipment life. For this reason, we provide a spherical simulated gemstone grinding device and a method of use. Summary of the invention

[0019] Place the grinding disc in the circular groove box and fix it through the anti-rotation structure and the limit mechanism; put the spherical simulated gemstone into the holder and adjust it to a suitable height through the hydraulic cylinder;

[0020] Before starting the equipment, let the clamp drive the spherical simulated gemstone to slowly descend, and continue to press down after the spherical simulated gemstone contacts the grinding disc until the round slot box presses down the rectangular plug rod to trigger the start switch.

[0023] Beneficial effects of the present invention:

[0024] The present invention arranges an axial rotating rod, a plug-in slot plug-in rod, a spring and a touch-start assembly, so that the circular groove box can drive the grinding disc to move downward, so that after the grinding disc is worn, it can be ensured that the spherical simulated gemstone always contacts the grinding disc and moves it downward to the lower end of the rectangular plug-in rod to touch the start switch, thereby ensuring the grinding effect each time and avoiding incomplete grinding caused by insufficient contact.

[0025] The present invention provides a pushing component and a limiting mechanism, so that when the grinding disc is worn and thinned, the descending length of the clamp will increase, and then when the grinding disc is completely unusable, the descending length of the hollow box can make the two triangular plates move relative to each other and allow the arc-shaped limiting plug to be pulled out from the limiting slot; during this period, the fixing plate touches the reverse start button to allow the hydraulic cylinder to drive the clamp to move up, and at this time the grinding disc inside the circular groove box will move up under the action of the spring four; the user can clean the uppermost grinding disc in time and continue to use it, avoiding poor grinding effect caused by damage to the grinding disc.

[0026] The present invention provides a counter and a counting button so that the user can clearly know the specific time to add the grinding disc, thereby avoiding the mechanical shutdown caused by untimely addition, which in turn leads to a reduction in grinding efficiency; and by providing a start switch, the drive motor is started only after the spherical simulated gemstone completes the perfect collision with the grinding disc, thereby avoiding the reduction in grinding effect caused by premature starting.

A plug-in slot 7 is vertically opened at the center of the upper end of the shaft rotating rod 6, and a plug-in rod 8 is inserted in the plug-in slot 7. A circular groove box 9 is fixedly mounted on the upper end of the plug-in rod 8, and a grinding disc 10 is placed in the circular groove box 9; a spring 11 is fixedly connected to the inner bottom wall of the plug-in slot 7, which is used to move the circular groove box 9 upward when it is not under force. A guide slot 12 is vertically provided on the periphery of the shaft rotating rod 6, and a guide slider 13 is fixedly connected to the periphery of the plug-in rod 8. The guide slider 13 is slidably connected in the guide slot 12 to ensure that the shaft rotating rod 6 can drive the plug-in rod 8 and the circular groove box 9 to rotate together when it rotates; the circular groove box 9 and the grinding disc 10 are connected by an anti-rotation structure, and the anti-rotation structure includes a hollow plug plate 23 fixedly installed on the inner bottom wall of the circular groove box 9 and a rectangular through groove 24 opened at the center of the grinding disc 10, and the hollow plug plate 23 is inserted in the rectangular through groove 24 to prevent the grinding disc 10 and the circular groove box 9 from rotating relative to each other; the hollow plug plate 23 and the grinding disc 10 are connected by a limiting mechanism, and the limiting mechanism includes a lap plate 26 fixedly installed on the inner wall of the hollow plug plate 23 and a limiting slot 25 opened on the end wall of the rectangular through groove 24. A strip through groove 27 is provided on the surface of the lap plate 26, and a movable sleeve block 30 is slidably connected in the strip through groove 27. An arc-shaped limit plug 31 is fixedly connected to the surface of one side of the movable sleeve block 30, and the arc-shaped limit plug 31 is inserted in the limit slot 25; a transverse fixing rod 28 is fixedly connected between the two end walls of the strip through groove 27, and a spring three 29 is sleeved on the outer periphery of the transverse fixing rod 28, one end of the spring three 29 is fixedly connected to the end wall of the strip through groove 27, and the other end is fixedly connected to the surface of the movable sleeve block 30, so as to maintain the stable position of the arc-shaped limit plug 31 in the limit slot 25.

[0041] Furthermore, a touch-start assembly is connected between the workbench 1 and the drive motor 5, and the touch-start assembly includes an L-shaped plate 14 fixedly mounted on the upper surface of the workbench 1 and a start switch 22, and the start switch 22 is electrically connected to the drive motor 5 through a wire. A rectangular through slot 15 is provided on the upper surface of the L-shaped plate 14, and a rectangular plug 16 is inserted into the rectangular through slot 15. The rectangular plug 16 is located directly above the start switch 22, and a ball 17 is connected to the upper end thereof in a rolling manner to reduce the friction with the lower surface of the circular slot box 9; a reset assembly is connected between the rectangular through slot 15 and the rectangular plug 16, and the reset assembly includes a strip groove 18 provided on the side of the rectangular plug 16 and a sliding sleeve 21 fixedly connected to the inner wall of the rectangular through slot 15. A vertical fixing rod 19 is fixedly connected between the two end walls of the strip groove 18, and a spring 20 is provided on the outer periphery of the vertical fixing rod 19. The upper end of the spring 20 is fixedly connected to the end wall of the strip groove 18, and the lower end is fixedly connected to the upper end surface of the sliding sleeve block 21, which is used to reset the rectangular insertion rod 16 when the circular groove box 9 moves upward.

[0042] Among them, when 4 clamps the spherical simulated gem and touches 10, 9 will move downward under the action of 7, 8 and 11, until the lower end surface of 9 touches 17 and pushes 16 to move downward; and the downward movement height of 16 is certain, until the lower end surface of 16 touches 22, so that 22 starts the rotation operation of 5; the advantage of this is that once 10 is worn, 4 clamps the spherical simulated gem until it touches the surface of 10 and then pushes 9 down, so that only the output length of 3 needs to be changed; in this way, it can ensure that each time the spherical simulated gem contacts 10, a better grinding effect can be achieved.

[0043] Furthermore, the clamp 4 is connected with a pushing component, which includes a fixed rod 33 fixedly mounted on the clamp 4, and the lower end of the fixed rod 33 is rotatably connected with a hollow box 34 through a bearing, and the hollow box 34 is located directly above the two triangular plates 32, and is used to push the two triangular plates 32 to produce relative movement during the downward movement; the outer periphery of the fixed rod 33 is fixedly connected with a fixed plate 35, and the inner wall of the fixed frame 2 is respectively fixedly connected with a connecting plate 36 and a counter 37. The upper end surface of the connecting plate 36 is respectively fixedly mounted with a counting button 38 and a reverse start button 39, and the counting button 38 is electrically connected to the counter 37 through a wire, and is used to count the number of replacements of the grinding disc 10. The reverse start button 39 is electrically connected to the hydraulic cylinder 3 through a wire, and is used for reverse starting of the hydraulic cylinder 3 during the replacement of the grinding disc 10; In addition, the outer periphery of the hollow plug plate 23 is also covered with a spring 40, and the lower end of the spring 40 is connected to the inner bottom wall of the circular groove box 9, and the upper end is in contact with the lower end of the lowest grinding disc 10. The spring 40 is designed to be in a compressed state and is used to provide an upward force when the grinding disc 10 is replaced.

[0044] As the surface of 10 is worn, the output length of 3 will change each time. When 3 drives 4 and the downward movement length of 33 is consistent with the designed thickness of 10, it means that 10 can no longer be used. At the same time, the process of 33 driving 34 downward will cause the two pieces 32 to move relative to each other, and then 30 drives 31 to move out of the inner wall of 25. The lower end surface of 35 will touch 38 and 39 at the same time. 38 makes 37 count plus one, and 39 makes 3 start in the reverse direction, and then drives 4 to move up. At this time, 10 is affected by the elastic force of 40 and three pieces move up at the same time. The user clears the top piece 10 away. ; When 3 is started again later, 4 drives the spherical simulated gem to continue to touch and press the top layer 10, so that 10 will move downward. Since the upper end of 31 is designed in an arc shape, 10 will squeeze and move 31 after moving downward. When the end of 31 is aligned with 25, 31 will be reset again with the cooperation of 28, 29 and 30 and inserted into the inner wall of 25; in this way, the removal and replacement of the top layer 10 is quickly completed; and so on, when the count of 37 reaches two, a new 10 can be added to supplement it; here, the design of 9 and 10 can be set according to needs, and is not limited to setting three 10s.

[0045] The working principle of the present invention 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 limit mechanism. Specifically, the rectangular through groove 24 in the center of the grinding disc 10 is aligned with the hollow plug plate 23 and inserted, and the movable sleeve block 30 is moved to insert the arc-shaped limit plug block 31 into the limit slot 25; the spherical simulated gem is placed in the clamp 4 and adjusted to a suitable height by the hydraulic cylinder 3. At this time, it should be noted that the clamp 4 is kept in a certain hovering state for subsequent operations; before starting the equipment, the clamp 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 plug rod 16 to trigger the start switch 22. At this time, the drive motor 5 is started, and the circular groove box 9 and the grinding disc 10 are driven to rotate through the shaft rotating rod 6, the plug rod 8 and the guide sliding structure. The spherical simulated gem is ground with the rotating grinding disc 10 under the fixation of the clamp 4; as the grinding proceeds, the grinding disc 10 will gradually wear and become thinner. When the grinding disc 10 is worn to a certain extent, it can be judged by observing the grinding effect or the number of replacements recorded by the counter 37, and the descending length of the clamp 4 will increase. At this time, the hollow box 34 will contact and push the two triangular plates 32 to move relative to each other, thereby driving the arc-shaped limit plug 31 to be pulled out from the limit slot 25, and releasing the fixation of the grinding disc 10. At the same time, the fixed plate 35 will touch the reverse start button 39, causing the hydraulic cylinder 3 to start in reverse and drive the clamp 4 and the spherical simulated gemstone to move up. At this time, under the action of the spring four 40, the top grinding disc 10 will move up and expose the grinding disc 10 or the empty space below; the user can take out and replace the worn grinding disc 10, or add a new grinding disc 10, and fix it again through the limit mechanism. Specifically, put the new grinding disc 10 into the circular slot box 9 and align the rectangular through slot two 24 in the center with the hollow plug plate 23 for insertion. Then move the movable sleeve block 30 so that the arc-shaped limit plug block 31 is inserted into the limit slot 25 again to fix the grinding disc 10; readjust the height of the clamp 4 and the spherical simulated gemstone according to the above steps, and perform the grinding operation again. During the entire grinding process, the number of replacements of the grinding disc 10 and the grinding effect recorded by the counter 37 should be continuously monitored to ensure the grinding quality and efficiency; after completing all grinding tasks, turn off the drive motor 5 and the hydraulic cylinder 3, and disconnect the power supply. Then clean the grinding chips and impurities on the workbench 1, the fixed frame 2, the round groove box 9 and other components to keep the equipment clean.
