Description

Technical Field

[0001] This utility model belongs to the field of diamond testing technology, and in particular relates to a diamond flaw detection and adjustment device. Background Technology

[0002] After diamonds are cut and polished into finished products, they need to be examined manually under a light source using optical inspection equipment such as a microscope to check for flaws. Currently, diamond flaw detection is mostly done manually by holding the diamond with tweezers under horizontal and bottom lighting, and examining it through a microscope. However, because diamonds are generally small, holding them with tweezers is inefficient, the diamond is prone to falling, and the detection efficiency is low.

[0003] In the prior art, for example, utility model patent CN212111166U discloses a diamond clarity testing device, including a frame; a fixed platform, fixedly mounted on the frame and used to store diamonds; a displacement device, fixedly mounted on the frame and located on one side of the fixed platform; a suction cup assembly, disposed on the displacement device, used to adsorb the diamond to be tested; an imaging device, disposed on the frame and located below the suction cup assembly, the displacement device used to move the suction cup assembly to pick up the diamond stored on the fixed platform and move it above the imaging device so that the imaging device can capture an image of the diamond; and an illumination device, disposed above the imaging device, used to illuminate the diamond to be tested so that the imaging device can image it. The diamond clarity testing device proposed in this utility model aims to solve the technical problems of cumbersome operation and low testing efficiency in existing diamond clarity testing methods.

[0004] The aforementioned utility model uses a suction cup assembly to adhere the diamond to the imaging device for detection. However, since the diamond cannot rotate, the imaging device primarily captures planar images, resulting in incomplete detection and an inability to fully determine the diamond's quality. While existing technologies allow for multiple images or observations of the same diamond placed at different horizontal angles, continuous rotational detection is still not possible. Furthermore, manually rotating the diamond multiple times for detection leads to low efficiency. Utility Model Content

[0005] To address the technical problems existing in the prior art, this application provides a diamond flaw detection and adjustment device that can be manually driven to continuously rotate a diamond to the required angle and has high detection efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A diamond flaw detection and adjustment device includes a fixed plate, a fixed block fixedly connected to the fixed plate, a horizontal tube fixedly inserted into the fixed block, a vertical tube at one end of the horizontal tube, an inner ring of a first bearing fixedly sleeved on the vertical tube and its outer ring fixedly inserted into a rotating sleeve, and the lower part of a diamond being able to be locked at the upper opening of the rotating sleeve; a fixed sleeve is provided on the horizontal tube, the outer ring of a second bearing is fixedly embedded in the fixed sleeve and its inner ring is fixedly sleeved on an adjusting shaft, and an adjusting handle is provided at the upper end of the adjusting shaft; synchronous teeth of the rotating sleeve and the adjusting shaft are respectively provided on the lower outer circumference of the rotating sleeve and the outer circumference of the adjusting shaft, and a synchronous belt meshes with the synchronous teeth of the rotating sleeve and the adjusting shaft; rotating the adjusting handle can drive the synchronous belt and the rotating sleeve to rotate.

[0007] Preferably, the horizontal and vertical tubes are internally interconnected, and a pipe joint is inserted at the end of the horizontal tube away from the rotating sleeve. The pipe joint is connected to a vacuum generator. The vacuum generator can suck away the air inside the rotating sleeve through the vertical and horizontal tubes to create a negative pressure state inside the rotating sleeve, thereby causing the diamond to be adsorbed onto the rotating sleeve.

[0008] Preferably, an elastic sleeve is fixedly embedded inside the rotating sleeve, and a slot matching the lower part of the diamond is provided at the upper opening of the elastic sleeve. The diamond is locked in the slot, and the elastic sleeve rotates synchronously with the rotating sleeve.

[0009] Preferably, a fixing tube is fixedly sleeved inside the vertical tube, and the upper part of the fixing tube extends into the elastic sleeve; the inner ring of the first bearing is fixedly sleeved on the fixing tube and its lower end face abuts against the upper end face of the vertical tube.

[0010] Preferably, the fixed pipe thread connection is inside the vertical pipe.

[0011] Preferably, a through hole for fixing the block is provided along the axial direction of the horizontal pipe on the fixing block, and a locking through slot is provided on the vertical end face of one side of the fixing block, which passes through the through hole for fixing. The locking bolt is rotatably inserted into the fixing block above the locking through slot and threadedly connected to the fixing block below the locking through slot.

[0012] Preferably, an installation sleeve is provided on a horizontal tube in a direction opposite to the fixing sleeve, and a gripping handle is fixedly inserted into the installation sleeve.

[0013] Preferably, the grip handle is threaded into the mounting sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model rotatably connects a rotating sleeve to a vertical pipe and an adjusting shaft to a fixed sleeve. By setting a synchronous belt assembly consisting of synchronous teeth on the rotating sleeve, synchronous teeth on the adjusting shaft, and a synchronous belt, a diamond can be embedded in the rotating sleeve. The diamond can be driven to rotate by manually rotating the adjusting handle on the adjusting shaft. Thus, the diamond can be continuously rotated to the required angle according to the diamond detection position. This improves detection efficiency, as well as the comprehensiveness and quality of the detection.

[0015] 2. Furthermore, this utility model improves the stability of the diamond when it is embedded in the rotating sleeve by setting a vacuum generating device to create a negative pressure state inside the rotating sleeve; by setting an elastic sleeve and a slot, the diamond and the elastic sleeve fit together better, which can improve the stability of the diamond embedded in the elastic sleeve; by setting a fixing tube, the suction force is closer to the diamond, which facilitates the diamond to be quickly adsorbed and fixed.

[0016] 3. Furthermore, by providing a through hole for the fixing block, a through groove for locking, and a locking bolt, the horizontal tube can be rotated around the axis of the horizontal tube when the locking bolt is loosened, thereby adjusting the tilt angle of the diamond; by providing a grip handle, it is convenient to rotate the horizontal tube in conjunction with the adjustment handle.

Therefore, they should not be construed as limitations on this utility model. Example 1

[0028] See appendix Figure 1 , 2 As shown in Figures 3 and 4, a diamond flaw detection adjustment device includes a fixing plate 1, which can be installed on an existing detection platform (not shown in the figure).

[0029] A fixing block 2 is fixedly installed on the fixing plate 1 by bolts. A fixing block through hole 21 is horizontally opened in the fixing block 2. A horizontal tube 3 is inserted into the fixing block through hole 21. A vertical tube 31 is provided at one end of the horizontal tube 3. The vertical tube 31 and the horizontal tube 3 are integrally formed and smoothly connected. The horizontal tube 3 is in the horizontal direction and the vertical tube 31 is in the vertical direction. The horizontal tube 3 is fixedly inserted into the fixing block through hole 21. Specifically, in this embodiment, the locking bolt 22 is threadedly connected to the upper end face of the fixing block 2 and abuts against the outer circumference of the horizontal tube 3.

[0030] A fixing tube 32 is fixedly inserted inside the vertical tube 31. The fixing tube 32 can be fixedly inserted into the upper opening of the vertical tube 31 by means of transition or interference fit, or it can be fixed into the upper opening of the vertical tube 31 by means of threaded connection. The inner ring of the first bearing 33 is fixedly sleeved on the outer circumference of the fixing tube 32 above the opening of the vertical tube 31, and the outer ring of the first bearing 33 is fixedly inserted into the rotating sleeve 34. With the above structure, the rotating sleeve 34 can rotate relative to the fixing tube 32 under the action of the first bearing 33. It should be noted that the lower end face of the inner ring of the first bearing 33 abuts against the upper end face of the vertical tube 31, thereby improving the stability of the rotation of the rotating sleeve 34 relative to the fixing tube 32.

[0031] The lower part of the diamond 4 can be directly locked at the upper opening of the rotating sleeve 34. To improve the stability of the diamond 4 locked at the upper opening of the rotating sleeve 34 and to prevent the diamond 4 from shaking or even falling off when the rotating sleeve 34 drives the diamond 4 to rotate synchronously, in this embodiment, an elastic sleeve 35 is fixedly embedded inside the rotating sleeve 34. The elastic sleeve 35 is made of an elastic material, such as rubber. The lower end face of the elastic sleeve 35 abuts against the upper end face of the outer ring of the first bearing 33. The rotating sleeve 34 can rotate synchronously with the elastic sleeve 35, and the upper opening of the fixing tube 32 extends into the elastic sleeve 35.

[0032] See Figure 7 As shown, a groove 351 matching the lower outer surface of the diamond 4 is provided at the upper opening of the elastic sleeve 35. The shape of the groove 351 matches the lower outer surface of the diamond 4, so that the lower outer surface of the diamond 4 fits into the groove 351, thereby improving the stability of the diamond 4 when placed in the upper opening of the elastic sleeve 35. For example, if the lower outer surface of the diamond 4 is provided with 16 equal facets, there are 16 corresponding grooves 35. The grooves 35 are formed by beveling the upper end of the elastic sleeve 35 towards the inside of the elastic sleeve 35. Each facet of the lower part of the diamond 4 fits into each groove 35 (i.e., the beveled facet).

[0033] See Figure 5 As shown, a fixing sleeve 36 is fixedly connected to the horizontal pipe 3. The axis of the fixing sleeve 36 is perpendicular to the axis of the horizontal pipe 3. The outer ring of the second bearing 361 is fixedly embedded in the fixing sleeve 36. An adjusting shaft 5 is fixedly inserted into the inner ring of the second bearing 361. The adjusting shaft 5 rotates synchronously with the inner ring of the second bearing 361, while the outer ring of the second bearing 361 and the fixing sleeve 36 remain stationary. The lower part of the adjusting shaft 5 is fixedly embedded in the inner ring of the second bearing 361, and the upper part of the adjusting shaft 5 is positioned above the second bearing 361. The outer diameter of the upper part of the adjusting shaft 5 is larger than the outer diameter of the lower part of the adjusting shaft 5. An adjusting handle 51 is horizontally fixedly connected to the upper end face of the upper part of the adjusting shaft 5. The outer diameter of the adjusting handle 51 is larger than the outer diameter of the upper part of the adjusting shaft 5.

[0034] See Figure 5 , 6As shown, a rotating sleeve synchronous tooth 341 and an adjusting shaft synchronous tooth 52 are respectively provided on the lower outer circumference of the rotating sleeve 34 and the upper outer circumference of the adjusting shaft 5. The synchronous belt 6 is sleeved on and meshes with the rotating sleeve synchronous tooth 341 and the adjusting shaft synchronous tooth 52. With the above structure, the rotating sleeve synchronous tooth 341, the adjusting shaft synchronous tooth 52 and the synchronous belt 6 constitute the existing synchronous belt mechanism. That is, when the adjusting handle 51 is rotated, the adjusting shaft 5 drives the adjusting shaft synchronous tooth 52, the synchronous belt 6, the adjusting shaft synchronous tooth 52, the rotating sleeve 34, the elastic sleeve 35 and the diamond 4 to rotate. Thus, the forward and reverse rotation of the diamond 4 can be adjusted according to the forward and reverse rotation of the adjusting handle 51, and the rotation speed of the diamond 4 can be adjusted according to the rotation speed of the adjusting handle 51.

[0035] like Figure 1 As shown, in operation, the fixing plate 1 of this diamond flaw detection and adjustment device is fixedly installed on the existing detection table. An annular bottom light source 71 is set below the vertical tube 31, and a horizontal light source 72 is set on one side of the rotating sleeve 34, so as to irradiate the diamond 4 from multiple directions. The diamond 4 is placed in the slot of the elastic sleeve 35, and the lens of the existing microscope or the existing photographic equipment is set above the diamond 4. The diamond 4 inside the elastic sleeve 35 is rotated by manually rotating the adjustment handle 51, so as to perform continuous and multi-angle detection of the diamond. Example 2

[0036] This embodiment is a further improvement on embodiment 1. Embodiment 1 can realize the rotation of diamond 4 in the horizontal direction. In this embodiment 2, diamond 4 is tilted by rotating and fixing the horizontal tube 3 to further detect different positions of diamond 4.

[0037] Specifically, in order to prevent the diamond 4 from falling out of the elastic sleeve 35 when tilted, in this embodiment, a vacuum generating device (not shown in the figure) is set to create a negative pressure state inside the elastic sleeve 35 below the diamond 4, so as to adsorb the diamond 4 onto the elastic sleeve 35.

[0038] Based on this, the horizontal pipe 3, the vertical pipe 31, and the fixed pipe 32 must all be hollow structures with openings at both ends, and their interiors must be interconnected. One end of the horizontal pipe 3 is fixedly connected to and connected to a pipe connector 37. The air inlet of the pipe connector 37 is connected to an existing vacuum generator. The vacuum generator can use an existing gas source and vacuum generator structure, that is, the high-pressure gas in the gas source can extract the air from the horizontal pipe 3 after passing through the vacuum generator. The other end of the horizontal pipe 3 is connected to one end opening of the vertical pipe 31, and the other end opening of the vertical pipe 31 is connected to the inner cavity of the elastic sleeve 35.

[0039] When it is necessary to adjust the horizontal angle of the horizontal tube 3, the vertical tube 31 and the rotating sleeve 34, the structure of Embodiment 1 can be referred to. The locking bolt 22 can be loosened to disengage the locking bolt 22 from the outer circumference of the horizontal tube 3. At this time, the horizontal tube 3 can be rotated, and then the locking bolt 22 can be tightened to fix the horizontal tube 3.

[0040] See Figure 8 As shown, in this embodiment, the following structure can be adopted: a through hole 21 is provided on the fixing block 2 along the axial direction of the horizontal tube 3; a locking groove 23 is provided on the vertical end face of one side of the fixing block 2, penetrating the through hole 21; and a locking bolt 22 is rotatably inserted into the fixing block 2 above the locking groove 23 and threadedly connected to the fixing block 2 below the locking groove 23. In this structure, the stability of the horizontal tube 3 fixed in the fixing block 2 is improved by increasing the contact area between the fixing block 2 and the outer circumference of the horizontal tube 3. To facilitate the rotation of the locking bolt 22, a locking handle 221 is integrally formed and horizontally fixedly connected to the upper end of the locking bolt 22.

[0041] Furthermore, to facilitate the rotation of the horizontal tube 3, a mounting sleeve 38 is fixedly connected to the horizontal tube 3 in the direction opposite to that of the fixed sleeve 36. The mounting sleeve 38 can be a nut structure welded to the horizontal tube 3. A gripping handle 39 is fixedly inserted into the mounting sleeve 38, and the gripping handle 39 can be threaded into the mounting sleeve 38. When it is necessary to rotate the horizontal tube 3, the gripping handle 39 and the adjusting handle 51 can be held and rotated to make the horizontal tube 3 rotate.

[0042] like Figure 1 As shown, in operation, the fixing plate 1 of this diamond flaw detection and adjustment device is fixedly installed on the existing detection table. An annular bottom light source 71 is set below the vertical tube 31, and a horizontal light source 72 is set on one side of the rotating sleeve 34, so as to irradiate the diamond 4 from multiple directions. The lens of the existing microscope or the existing photographic equipment is set above the rotating sleeve 34. After loosening the locking bolt 22 by tightening the locking handle 221, hold the adjusting handle 51 and the holding handle 39 to rotate the horizontal tube 3 to the required angle, and then tighten the locking bolt 22 by tightening the locking handle 221 to fix the horizontal tube 3 in the through hole 21 of the fixing block; place the diamond 4 in the slot 351 on the elastic sleeve 35, start the vacuum generator, and suck away the air in the rotating sleeve 34 through the vertical tube 31 and the horizontal tube 3 to create a negative pressure state in the rotating sleeve 34, so that the diamond 4 is adsorbed on the rotating sleeve 34; then manually rotate the adjusting handle 51 to drive the diamond 4 in the elastic sleeve 35 to rotate, thereby performing continuous, multi-angle detection of the diamond.

[0043] It should be noted that, in order to improve the connection strength between the horizontal pipe 3 and the fixed block 2 and the ease of operating the horizontal pipe 3, in this embodiment, the horizontal pipe 3 can be divided into two internally interconnected sections: a thin horizontal pipe section 301 connected to the vertical pipe 31 and a thick horizontal pipe section 302 connected to the fixed block 2. The outer diameter of the thick horizontal pipe section 302 is larger than the outer diameter of the thin horizontal pipe section 301. The fixing sleeve 36, pipe joint 37, and mounting sleeve 38 are all provided on the thick horizontal pipe section 302. In use, the diamond 4 only needs to be slightly tilted and does not need to be deflected at a large angle. In addition, the connecting pipe between the pipe joint 37 and the vacuum generator can be a flexible hose to facilitate the horizontal pipe 3 to rotate it at a small angle.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
