Description

Technical Field

[0001] The present invention relates to the technical field of gemstone processing, in particular to a sapphire precise positioning and cutting device. Background Art

[0002] A carved diamond is what we usually call a diamond. Diamond is very hard. Originally, diamonds were cut by hand. With the development of technology, diamond cutting machines have appeared. However, a rough diamond must go through a series of cutting and processing before it can become a sparkling diamond. In order to ensure the cleanliness and integrity of the diamond as much as possible, very precise judgment is required during processing.

[0003] For example, an application document with announcement number CN102528958A discloses a gem cutting positioning device, which is used to clamp a fixed rod with a gem contained at one end. The gem cutting positioning device includes: a rotating shaft, a fixed sleeve and a positioning component, and the rotating shaft is inserted into the fixed sleeve; one end of the rotating shaft is pivotally connected to an external driving device and rotates relative to the fixed sleeve under the drive of the external driving device, and the other end is fixedly connected to the external gem fixing rod; the positioning component is arranged between the fixed sleeve and the external driving device, and is used to limit the rotation of the rotating shaft. The positioning device has a simple structure, is convenient and practical, and solves the problem of rotation during the gem cutting process without the need for complex principles and equipment, and can realize multi-angle processing of gems, and even processing of gems at any angle, greatly improving the utilization efficiency of the gem cutting machine and ensuring the cutting accuracy of the gem during rotation.

[0004] In order to solve the problem of rotation during gemstone cutting, the existing cutting and positioning device installs a fixed structure for fixing the gemstone on a rotating shaft, fixes the angle of the cutting tool, and realizes multi-angle cutting by rotating the gemstone through the rotating shaft. However, during actual cutting, due to the different shapes of the gemstone raw materials and the different slopes of the bevels of the cut gemstones, it is impossible to achieve cutting of multiple bevels with different slopes by simply rotating the gemstone itself. At the same time, the gemstone has multiple facets, and it is impossible to accurately locate the specific processing facet. Summary of the Invention

[0005] In view of the above-mentioned shortcomings, the purpose of the present invention is to provide a sapphire precise positioning and cutting device to achieve multi-angle adjustment and ensure cutting efficiency.

[0006] The present invention provides the following technical solutions:

It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other in the absence of conflict.

[0029] Example 1

[0030] Please refer to Figures 1 to 5 As shown, the present application provides a sapphire precise positioning and cutting device, including a linkage processing table 14, on which a mounting seat 13 for clamping the workpiece and a cutting frame for mounting the cutting piece 28 are installed. A suction cup 4 is movably installed in the mounting seat 13 for fixing the workpiece, and the suction cup 4 is made of rubber so that it can stick closely to the surface of the workpiece.

[0031] A cutting assembly is installed on the cutting frame, wherein the cutting frame includes a symmetrically set side cutting frame 11 and a top frame 12 installed on the side cutting frame 11, the side cutting frame 11 is provided with a rotating groove 22, and both ends of the top frame 12 are located in the rotating groove 22; the cutting assembly includes an angle adjustment part, which is movably installed on the cutting frame for adjusting the angle of the cutting piece 28 to realize the swinging cutting action of the cutting piece 28.

[0032] Specifically, the angle adjustment portion includes a side slide rail 26 , which is mounted on the side section frame 11 , and a top slide rail 24 is mounted on the top frame 12 .

[0033] The swinging cutting action of the cutting piece 28 is achieved by the rotation of the side slide rail 26 and the swinging of the top slide rail 24, wherein the rotation of the side slide rail 26: a rotating block 23 is installed on the side slide rail 26, and the rotating block 23 passes through the side cutting frame 11 and extends to the outside of the side cutting frame 11, so that the side slide rail 26 rotates together with the rotating block 23, and a power source 19 is installed on the side cutting frame 11, and the power source 19 is located below the rotating block 23, and a central rotating shaft 21 passes through the rotating block 23, and a gear set 20 is installed on the power source 19 and the central rotating shaft 21, and the power source 19 transmits power to the central rotating shaft 21 through the gear set 20, so that the rotating block 23 and the central rotating shaft 21 rotate together.

[0034] The swinging of the top slide rail 24: that is, the top frame 12 swings in the rotating groove 22. At the same time, end protrusions 16 are installed at both ends of the top frame 12. The end protrusions 16 are located outside the rotating groove 22, and the height of the end protrusions 16 is greater than the height of the rotating groove 22, ensuring that the top frame 12 swings smoothly in the rotating groove 22. In order to further synchronize the rotation of the side slide rail 26 and the swinging of the top slide rail 24, a connecting rod 18 is connected between the rotating block 23 and the end protrusion 16, and the end protrusion 16 swings with the rotation of the rotating block 23 through the connecting rod 18.

[0035] A side slider 27 is slidably connected to the side slide rail 26, and a top slider 25 is slidably connected to the top slide rail 24. The structure of the side slider 27 is the same as that of the top slider 25. An arc groove 29 is provided on the side slider 27 and the top slider 25. The cutting piece 28 is hinged in the arc groove 29. The movement of the top slider 25 on the top slide rail 24 and the movement of the side slider 27 on the side slide rail 26 are coordinated, thereby changing the inclination angle of the cutting piece 28 and the surface of the linkage processing table 14. At this time, the inclination angle of the cutting piece 28 and the surface of the linkage processing table 14 is the inclination angle of the gem facet and the top plane.

[0036] A support platform 7 is installed at the bottom end of the linkage processing table 14, and a lifting cylinder 8 is installed on the support platform 7. The top of the lifting cylinder 8 is connected to the mounting seat 13. The height of the mounting seat 13 can be adjusted to facilitate moving the cutting surface to the cutting trajectory of the cutting piece 28. A rotating drive part 6 is installed at the bottom end of the linkage processing table 14.

[0037] During cutting, the lifting cylinder 8 lifts the mounting seat 13, and the rotary drive member 6 drives the linked processing table 14 to rotate for cutting, thereby retaining the volume of the cut waste to the greatest extent, so as to utilize the waste and improve the utilization rate of the gemstone rough stone.

[0038] In order to further accurately control the cutting angle, an indicator needle 15 is installed on the end protrusion 16, and an angle scale line 17 is provided on one side of the side section frame 11. The angle scale line 17 is located above the end protrusion 16. The scale indicated by the indicator needle 15 at the point where the indicator needle 15 and the angle scale line 17 overlap is the inclination angle of the cutting piece 28, which makes it easy to intuitively obtain the inclination angle value of the cutting piece 28.

[0039] In order to shorten the cutting time and improve the cutting efficiency, the cutting frame is symmetrically provided with an angle adjustment part. When working, the gemstone is rotated and cut by rotating the linkage processing table 14.

[0040] Among them, a CCD component 30 is installed on the top frame 12, and the CCD component 30 is located between the symmetrically set angle adjustment parts. When installed, the CCD component 30 faces the mounting seat 13. During cutting processing, the gem cutting situation is monitored by the CCD component 30, which facilitates timely control of the stopping of cutting.

[0041] Example 2

[0042] On the basis of the above-mentioned embodiment 1, a linkage groove 3 is provided on the linkage processing table 14. When the mounting seat 13 is located in the linkage groove 3, the mounting seat 13 and the linkage processing table 14 move together.

[0043] Specifically, the linkage groove 3 is a polygonal groove body, and the surface of the mounting seat 13 is fitted with the surface of the linkage groove 3. Preferably, the outer surfaces of the linkage groove 3 and the mounting seat 13 are both pentagonal when viewed from above. At this time, the adjustment of the cutting surface can be completed by adjusting the rotation of the gem. Finally, the mounting seat 13 and the linkage groove 3 are separated, and the rotation of the linkage processing table 14 completes the cutting of the cutting surface without adjusting the cutting angle of the cutting piece 28.

[0044] Other components and principles in this embodiment are the same as those in the first embodiment.

[0045] Example 3

[0046] On the basis of the above-mentioned embodiment 2, in order to further position the linkage processing table 14 and the mounting seat 13, a plurality of positioning holes 5 are provided on the linkage processing table 14, and the positioning holes 5 are distributed in a circle. A positioning cylinder 1 is installed on the support table 7, and a positioning member 2 is installed on the positioning cylinder 1. When the positioning member 2 is located in the positioning hole 5, the position of the linkage processing table 14 is fixed. At this time, it is only necessary to make the linkage processing table 14 reciprocate to cut the facets of the gemstone. Specifically, the positioning member 2 is located in the outer sleeve 10, and a spring body 9 is provided on the positioning member 2 to buffer the positioning member 2.

[0047] As a further technical solution, the number and positions of the positioning holes 5 on the linkage processing table 14 are equal to and aligned with the surface of the gemstone to be cut, that is, when the positioning member 2 is located in the positioning hole 5, the linkage processing table 14 makes a reciprocating motion of a certain amplitude to complete the cutting. At the same time, the inclination angle of the cutting member 28 relative to the processing surface of the linkage processing table 14 in Example 1 is adjusted to complete the swing cutting of the gemstone surface and meet the cutting accuracy requirements.

[0048] Other components and principles in this embodiment are the same as those in the second embodiment.

[0049] The cutting principle of the present invention is:

[0050] Fine cutting (cutting a single side of a gemstone):

[0051] The top slider 25 moves on the top slide rail 24 and the side slider 27 moves on the side slide rail 26 to adjust the inclination angle of the cutting member 28 relative to the processing surface of the linkage processing table 14;

[0052] The mounting seat 13 fixes the workpiece (gemstone), the lifting cylinder 8 pulls the mounting seat 13 into the linkage groove 3, and the rotary drive member 6 drives the mounting seat 13 and the linkage processing table 14 to rotate together, so that the positioning cylinder 1 pushes the positioning member 2 up to the positioning hole 5 corresponding to the cutting surface, and the lifting cylinder 8 pushes the mounting seat 13 up until it is out of the linkage groove 3. At this time, the cutting position of the workpiece is located on the rotation cutting trajectory of the cutting member 28, and the rotary drive member 6 drives the linkage processing table 14 to rotate to cut the workpiece.

[0053] Rough cut (a single rotary cut of the gemstone):

[0054] The top slider 25 moves on the top slide rail 24 and the side slider 27 moves on the side slide rail 26 to adjust the inclination angle of the cutting member 28 relative to the processing surface of the linkage processing table 14;

[0055] The power source 19 transmits power to the rotating block 23 through the gear set 20. The side slide rail 26 rotates along with the rotating block 23. The top frame 12 moves in the rotating groove 22, changing the inclination angle of the cutting member 28 itself.

[0056] The lifting cylinder 8 pushes up the mounting seat 13 so that the cutting position of the workpiece is located on the rotation cutting track of the cutting member 28, and the rotary driving member 6 drives the linkage processing table 14 to rotate to cut the workpiece.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
