Description

Technical Field

[0001] The utility model belongs to the field of artificial synthesis of diamonds, and particularly relates to a multi-angle adjustable diamond cutting auxiliary positioning device. Background Art

[0002] See the attached drawings of the specification Figure 5 Gem-grade single-crystal diamonds artificially grown using the CVD process are generally columnar polyhedrons. During the growth process, irregular polycrystalline regions will grow on the edges of the crystals. The polycrystalline regions have a certain depth and tilt angle, which will affect the quality of the diamond and must be removed before further processing. Figure 6 The existing cutting method is to use laser cutting. Since it is impossible to accurately measure the depth and tilt angle of the polycrystalline area, the angle of the cutting laser is usually fixed, and the cutting is performed in a vertical manner. This cutting method not only cannot accurately cut off all the polycrystalline, but also cuts off the single crystals in the normal area, causing material loss and waste. Utility Model Content

DETAILED DESCRIPTION

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] To achieve the above purpose, the technical solution of the utility model is as follows:

[0025] like Figure 1-7 As shown, this embodiment provides a multi-angle adjustable diamond cutting auxiliary positioning device, see Figure 1-4 , including a base 1, a multi-stage rotating structure 2, and a sample positioning member 3, wherein the sample positioning member 3 is connected to the base 1 through the multi-stage rotating structure 2.

[0026] Furthermore, the multi-stage rotating structure 2 includes a first-stage rotating member 21, a second-stage rotating member 22, and a third-stage rotating member 23 with scales.

The sample positioning member 3 is fixed to the third-stage rotating member 23, and the rotation directions of the first-stage rotating member 21, the second-stage rotating member 22, and the third-stage rotating member 23 are perpendicular to each other. The sample positioning member 3 can be rotated in three dimensions, and then the angle of the crystal can be adjusted in three dimensions, thereby realizing precise adjustment of the crystal inclination and facilitating cutting of the crystal at various angles.

[0027] Further, the primary rotating member 21 includes a primary rotating body 211 and a first rotating dial 212, the first rotating dial 212 is attached to one end of the primary rotating body 211, a first rotating shaft 4 is provided on the base 1, the first rotating shaft 4 is rotatably connected to the middle of the first rotating dial 212, and a first pointer 5 that cooperates with the first rotating dial 212 is also provided on the side where the base 1 is connected to the primary rotating member 21. In the present application, when the primary rotating member 21 rotates relative to the base 1, the angle of rotation can be observed through the cooperation between the first pointer 5 and the first rotating dial 212, so as to facilitate the precise adjustment of the angle of the sample positioning member 3.

[0028] Furthermore, the secondary rotating member 22 includes a secondary rotating body 221 , one end of which is provided with a hinge 222 , and a second rotating shaft 223 is provided on the hinge 222 . One end of the primary rotating body 211 away from the first rotating dial 212 is rotatably connected to the second rotating shaft 223 .

[0029] Furthermore, a second rotating scale plate 224 perpendicular to the axial direction of the second rotating shaft 223 is connected thereto, and a second pointer 213 cooperating with the second rotating scale plate 224 is provided on the primary rotating body 211. In the present application, when the secondary rotating member 22 rotates relative to the primary rotating member 21, the rotation angle of the secondary rotating member 22 can be observed through the cooperation between the second pointer 213 and the second rotating scale plate 224, so as to accurately adjust the angle of the sample positioning member 3.

[0030] Further, the tertiary rotating member 23 includes a third rotating shaft 231 and a third rotating dial 232. The third rotating dial 232 is fitted and connected to one end of the third rotating shaft 231. A rotating hole 225 is provided on the secondary rotating body 221. The third rotating shaft 231 is rotatably connected in the rotating hole 225. The outer side surface of the secondary rotating body 221 is also provided with a third pointer 226 that cooperates with the third rotating dial 232. In the present application, when the tertiary rotating member 23 rotates relative to the secondary rotating member 22, the rotation angle of the tertiary rotating member 23 can be observed through the cooperation of the third pointer 226 and the third rotating dial 232, so as to accurately adjust the angle of the sample positioning member 3.

[0031] Furthermore, the first rotating shaft 4, the second rotating shaft 223, and the third rotating shaft 231 are all perpendicular to each other, the third rotating shaft 231 is provided with a mounting hole along its axial direction, the sample positioning member 3 includes a connecting rod 31 and a sample positioning portion 32, the sample positioning portion 32 is connected to the connecting rod 31, and the connecting rod 31 is passed through the mounting hole. Through the above structural arrangement, the rotation directions of the primary rotating member 21, the secondary rotating member 22, and the tertiary rotating member 23 can be made perpendicular to each other.

[0032] Further, the bottom surface of the base 1 is a horizontal plane, the end surface of the sample positioning portion 32 is a horizontal plane, and a spirit level 6 is also installed on the base 1. During use, the crystal is adhesively fixed to the end surface of the sample positioning portion 32, which can ensure that the initial angle of the crystal is horizontal.

Both inner side surfaces of the horizontal adjusting member 7 are horizontal planes, and one of the outer side surfaces of the horizontal adjusting member 7 is connected to the end surface of the sample positioning portion 32. In this application, artificially cultivated gem - grade diamond products generally have a flat bottom surface and an uneven growth surface. When positioning the crystal with the cutting auxiliary positioning device and cutting the bottom polycrystal, due to the uneven growth surface, if the growth surface of the crystal is directly adhered to the sample positioning portion 32, the crystal will not be horizontally placed, affecting the cutting. At this time, by setting the "U" - shaped horizontal adjusting member 7, placing the crystal in its "U" - shaped groove and adhering its flat bottom surface to the inner side wall, it can not only ensure the correct direction of the crystal but also ensure that the surface to be cut is horizontal, facilitating subsequent cutting adjustment.

[0034] Further, in step S5, the cutting operator fixes the bottom surface (plane) of the crystal to the sample positioning portion, and then inserts the sample positioning member 3 into the mounting hole. By rotating the first - stage rotating member 21 or the second - stage rotating member 22 or the third - stage rotating member 23, the sample is tilted, and the scale indicated by the pointer represents the current tilt angle. The tilt angle is adjusted to the cutting tilt angle. Then, control the laser to cut along the cutting route of the growth surface. After cutting one side, repeat the operation on the other side until all the polycrystals are removed. When one side of the sample is not horizontal, use the double - vertical "U" - shaped horizontal adjusting member 7, stick one end of the sample to the inner side of the "U" - shaped horizontal adjusting member 7, and stick one end of the horizontal adjusting member 7 to the sample positioning portion to make the cutting surface of the crystal parallel to the end surface of the sample positioning portion.

[0035] In this embodiment, through the cutting auxiliary positioning device capable of three - dimensional rotation, the crystal sample placed thereon can realize three - dimensional 360° rotation inside the cutting machine. Technicians give the thickness and angle data of each polycrystalline surface of the crystal sample through instruments such as microscopes, vernier calipers, and protractors. The cutting operator can cut according to the given angle and cutting depth to accurately remove the diamond polycrystals and maximize the retention of the main body weight.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
