Description

Technical Field

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

[0002] In the process of preparing artificial diamonds by CVD (chemical vapor deposition), natural diamonds are first laser-cut into slices, and then the cut surfaces are manually polished to make them clean and smooth. After that, they are placed in CVD artificial diamond preparation equipment, where plasma is deposited on the cut surfaces to grow artificial diamonds.

[0003] In existing technology, when polishing the facets of a diamond-forming substrate (i.e., a sliced ​​natural diamond), the diamond-forming substrate is first fixedly bonded to one end of an adhesive rod using an adhesive such as epoxy resin, and then the other end of the adhesive rod is clamped onto a polishing fixture. An existing polishing fixture, such as the diamond polishing fixture disclosed in Chinese Utility Model Patent No. CN209579215U, includes a base and a positioning post fixedly connected to the base. A guide strip is provided on the top surface of the base, the axis of which is parallel to the moving direction of the fixture, and the guide strip includes a sliding surface that slides against the fixture. This utility model has the advantage of improved practicality.

[0004] Furthermore, Chinese invention patent CN109702584B discloses a diamond polishing device and process, including a worktable, a polishing disc, a diamond clamp, and auxiliary fixtures. The diamond clamp includes a connecting arm, a support base, and an orientation adjustment chuck. A strip block is fixedly connected to one end of the connecting arm, and a sliding groove is formed along the length of the strip block. A connecting block is movably inserted into the sliding groove. The orientation adjustment chuck is fixedly connected to the connecting block. A spring is provided between the connecting block and the sliding groove. A baffle is slidably connected to the sliding groove of the connecting arm. When the baffle abuts against the connecting block, the spring is compressed. The connecting arm is provided with a sliding assembly for driving the baffle to slide. A triggering device is provided between the diamond clamp and the disc for triggering the sliding assembly to drive the baffle away from the connecting block. This invention also provides a diamond polishing process. Through the above structure and method, the endpoint of tabletop polishing can be accurately determined, which has the advantages of improving work efficiency and improving the quality of finished diamond products.

[0005] Existing diamond polishing fixtures have the following technical problems: After the bonding rod with the bonded diamond substrate is vertically fixed on the polishing fixture, the polishing fixture is placed on the worktable by hand and pressed down to make the cut surface of the diamond substrate contact the rotating polishing disc to polish the cut surface of the diamond substrate. After the initial polishing, the polishing fixture needs to be picked up and flipped so that the cut surface of the diamond substrate faces the polishing worker to judge the polishing quality and degree. Then the polishing fixture is placed on the worktable for secondary polishing until the required polishing effect is achieved.

[0006] In the aforementioned process, the polishing effect needs to be checked multiple times, requiring the polishing fixture to be picked up and flipped repeatedly. Since the polishing fixture has a certain weight, this increases the labor intensity for workers polishing diamonds and reduces polishing efficiency. While existing technologies use quick-release structures to directly remove the bonding rod for observation, these still suffer from low polishing efficiency, and each clamping operation can only hold one bonding rod with a diamond-forming substrate, further limiting polishing efficiency. Utility Model Content

[0007] To address at least one technical problem in the existing technology, this application provides a diamond polishing device with a simple structure, convenient for viewing the diamond polishing effect, and capable of clamping multiple diamond bonding rods.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A diamond polishing device includes a base, a column vertically fixedly connected to the base, a longitudinal spring sleeved on the column, a locking block slidably sleeved on the column above the longitudinal spring, a guide rod horizontally fixedly connected to the locking block, a limiting plate fixedly connected to one end of the guide rod away from the locking block, a mounting sleeve rotatably and slidably sleeved on the guide rod inside the limiting plate, a plurality of threaded connection holes evenly distributed on the outer circumference of the mounting sleeve, and an adhesive rod threadedly connected to the corresponding connection hole; a transverse spring sleeved on the guide rod between the mounting sleeve and the locking block.

[0009] Preferably, an adjusting sleeve is slidably fitted on the column, the lower end of the longitudinal spring abuts against the adjusting sleeve, and the adjusting bolt is threadedly connected to the outer circumference of the adjusting sleeve and abuts against the column to fix the relative position of the adjusting sleeve on the column.

[0010] Preferably, an adjustment knob is fixedly connected to the adjustment bolt on the outside of the adjustment sleeve.

[0011] Preferably, a limiting groove is formed on the upper end face of the adjusting sleeve, and the lower end of the longitudinal spring is embedded in the limiting groove.

[0012] Preferably, a guide post is provided on the end face of the mounting sleeve opposite to the limiting plate, and a guide ring groove matching the guide post is provided on the end face of the limiting plate opposite to the mounting sleeve, so that the guide post can slide along the guide ring groove when the mounting sleeve is driven to rotate.

[0013] Preferably, multiple guide posts are evenly distributed on the mounting sleeve, and positioning holes matching the guide posts are evenly distributed at the bottom of the guide ring groove, so that the guide posts can be embedded in the positioning holes.

[0014] Preferably, a horizontal washer is slidably fitted on the column between the longitudinal spring and the lower end face of the locking block.

[0015] Preferably, a longitudinal washer is slidably sleeved on the guide rod between the mounting sleeve and the transverse spring.

[0016] Preferably, a sliding sleeve is fixedly embedded in the locking block, and the sliding sleeve is slidably sleeved on the column.

[0017] Preferably, the locking block includes a longitudinal locking through hole and a transverse locking through hole with their axes perpendicular to each other. A longitudinal locking groove and a transverse locking groove are respectively provided at both ends of the locking block, which are parallel to the axes of the longitudinal locking through hole and the transverse locking through hole. The longitudinal locking groove connects the longitudinal locking through hole and the outside of the locking block, and the transverse locking groove connects the transverse locking through hole and the outside of the locking block. The sliding sleeve and the guide rod are respectively fixedly embedded in the longitudinal locking through hole and the transverse locking through hole by locking bolts.

[0018] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model comprises a base, a column, a longitudinal spring, and a locking block. The locking block can slide up and down on the column and reset under the action of the longitudinal spring. By incorporating the locking block, a guide rod, a limiting disc, a mounting sleeve, and a transverse spring, the worker can achieve a damped rotation of the mounting sleeve under the elastic force of the transverse spring, thereby rotating the bonding rod mounted on the mounting sleeve. This facilitates the inspection of the polishing effect of the diamond-forming substrate bonded to the bonding rod. The utility model has a simple structure. When the worker presses down the locking block, the diamond-forming substrate's cut surface contacts the polishing disc for polishing. When it is necessary to inspect the polishing effect of the diamond-forming substrate's cut surface, the mounting sleeve can be rotated to rotate the bonding rod, thus allowing inspection of the diamond-forming substrate. Multiple connecting holes on the mounting sleeve allow for the simultaneous clamping of multiple diamond bonding rods.

[0019] 2. The height of the longitudinal spring can be adjusted by setting an adjusting sleeve and adjusting bolts to adjust the height of the locking block; the guide post and guide ring groove guide the mounting sleeve when rotating; the positioning hole is set so that the guide post is embedded in the positioning hole during the grinding process, preventing the bonding rod from rotating when grinding the diamond substrate surface. When inspecting the diamond substrate surface, the mounting sleeve can be pulled to disengage the guide post from the positioning hole so that the mounting sleeve can be rotated.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0030] See appendix Figure 1 , 2 As shown, a diamond polishing device includes a base 1, a column 2, an adjusting sleeve 3, a longitudinal spring 4, a locking block 5, a guide rod 6, a mounting sleeve 7, and a transverse spring 8.

[0031] See Figure 3 As shown, the base 1 includes a base plate 11 that is detachably and horizontally fixed to an existing workbench, and a cylindrical fixing platform 12 fixedly connected to the upper end face of the base plate 11. A fixing hole 121 is vertically opened on the upper end face of the fixing platform 12, and a fastening hole 122 is horizontally opened on the outer circumference of the fixing platform 12. The fastening hole 122 communicates with the fixing hole 121. The column 2 is inserted into the fixing hole 121, and the fixing bolt 123 is threaded into the fastening hole 122 and abuts against the circumference of the column 2, thereby fixing the column 2 in the fixing platform 12.

[0032] See Figure 2 , 4 As shown, an adjusting sleeve 3 is slidably fitted onto the column 2 above the fixed platform 12. The adjusting sleeve 3 has a cylindrical structure, and an adjusting bolt 31 is threaded onto the outer circumference of the adjusting sleeve 3 and abuts against the column 2, thereby fixing the adjusting sleeve 3 at a certain position on the column 2. To facilitate tightening and loosening of the adjusting bolt 31, an adjusting knob 32 is fixedly connected to the adjusting bolt 31 on the outside of the adjusting sleeve 3.

[0033] A longitudinal spring 4 is fitted onto the column 2 above the adjusting sleeve 3. A limiting groove 33 is formed on the upper end face of the adjusting sleeve 3, and the lower end of the longitudinal spring 4 is embedded in the limiting groove 33. A locking block 5 is slidably fitted onto the column 2 above the longitudinal spring 4. Thus, the longitudinal spring 4 can be compressed by pressing down the locking block 5. The height of the locking block 5 on the column 2 can be adjusted by adjusting the relative height of the adjusting sleeve 3 on the column 2. Therefore, the height of the locking block 5 and the compression range of the longitudinal spring 4 can be adjusted according to the different operating habits or heights of different workers.

[0034] In addition, the locking block 5 can also rotate relative to the column 2. In order to make the locking block 5 rotate smoothly, in this embodiment, a horizontal washer 21 can be slidably sleeved on the column 2 between the longitudinal spring 4 and the lower end face of the locking block 5 along the axial direction of the column 2.

[0035] Furthermore, in order to make the locking block 5 slide smoothly along the axial direction of the column 2 and rotate smoothly along the axial direction of the vertical shaft 2, in this embodiment, a sliding sleeve 22 is fixedly embedded in the locking block 5. The sliding sleeve 22 can be slidably sleeved on the column 2, and the sliding sleeve 22 can be an existing linear bearing structure.

[0036] See Figure 5 As shown, to facilitate the installation of the sliding sleeve 22 and guide rod 6 on the locking block 5, the locking block 5 is generally a cuboid structure. The locking block 5 has a longitudinal locking through hole 51 and a transverse locking through hole 52 with their axes perpendicular to each other. In actual installation, the longitudinal locking through hole 51 is vertical, and the transverse locking through hole 52 is horizontal. At both ends of the locking block 5, there are longitudinal locking grooves 53 and transverse locking grooves 54, parallel to the axes of the longitudinal locking through hole 51 and the transverse locking through hole 52, respectively. The longitudinal locking groove 53 connects the longitudinal locking through hole 51 and the outer side of the locking block 5, and the transverse locking groove 54 connects the transverse locking through hole 52 and the outer side of the locking block 5. The sliding sleeve 22 and guide rod 6 are respectively fixedly embedded in the longitudinal locking through hole 51 and the transverse locking through hole 52 by locking bolts 55.

[0037] When the sliding sleeve 22 is inserted into the longitudinal locking through hole 51, the locking bolt 55 can be rotatably inserted into the locking block 5 on one side of the longitudinal locking groove 53 and threadedly connected to the locking block 5 on the other side of the longitudinal locking groove 53. The locking blocks 5 on both sides of the longitudinal locking groove 53 clamp and fix the sliding sleeve 22. Similarly, when the horizontally arranged guide rod 6 is inserted into the transverse locking through hole 52, the locking bolt 55 can be rotatably inserted into the locking block 5 on one side of the transverse locking groove 54 and threadedly connected to the locking block 5 on the other side of the transverse locking groove 54. The locking blocks 5 on both sides of the transverse locking groove 54 clamp and fix the guide rod 6.

[0038] See Figure 7As shown, a limiting disc 61 is fixedly connected to one end of the guide rod 6 away from the locking block 5. The limiting disc 61 is integrally formed and fixedly installed with the guide rod 6, and the outer diameter of the limiting disc 61 is larger than the outer diameter of the guide rod 6. When in the installation state, the guide rod 6 is in a horizontal state, and the limiting disc 61 is in a vertical state.

[0039] An mounting sleeve 7 is slidably fitted onto the guide rod 6 inside the limiting plate 61 along the axial direction of the guide rod 6. Several threaded connection holes 71 are evenly distributed around the outer circumference of the mounting sleeve 7. In this embodiment, four connection holes 71 are evenly distributed, and the axis of the connection holes 71 is perpendicular to the axis of the mounting sleeve 7. One end of the existing adhesive rod 9 is bonded to a diamond-forming substrate 91, and the other end is threaded into the corresponding connection hole 71. A transverse spring 8 is fitted onto the guide rod 6 between the mounting sleeve 7 and the locking block 5. When in the installed state, the transverse spring 8 is in a horizontal state.

[0040] Furthermore, in order to improve the smoothness of sliding and rotating of the mounting sleeve 7 relative to the guide rod 6, in this embodiment, a longitudinal pad 62 is slidably mounted on the guide rod 6 between the mounting sleeve 7 and the transverse spring 8. The outer diameter of the longitudinal pad 62 is larger than the outer diameter of the transverse spring 8. Under the elastic force of the transverse spring 8, the two end faces of the longitudinal pad 62 abut against the transverse spring 8 and the mounting sleeve 7, respectively.

[0041] Through the structure of the locking block 5 and the guide rod 6, the compression degree of the transverse spring 8 can be adjusted by adjusting the depth of the guide rod 6 inserted into the transverse locking through hole 52.

[0042] See Figure 6 , 7 As shown, guide posts 72 are provided on the end face of the mounting sleeve 7 opposite to the limiting plate 61. The guide posts 72 are integrally formed with the mounting sleeve 7 and are arranged parallel to the axis of the mounting sleeve 7. In this embodiment, four guide posts 72 are evenly distributed. A guide ring groove 611 matching the guide posts 72 is provided on the end face of the limiting plate 61 opposite to the mounting sleeve 7. When the mounting sleeve 7 is driven to rotate, the guide posts 72 can slide along the guide ring groove 611.

[0043] To prevent the bonding rod 9 from rotating due to friction during the grinding of the diamond-forming substrate 91, in this embodiment, positioning holes 612 matching the guide posts 72 are evenly distributed at the bottom of the guide ring groove 611. In the initial state, when the mounting sleeve 7 abuts against the limiting plate 61, each guide post 72 is embedded in the corresponding positioning hole 612.

[0044] It should be noted that the positioning holes 612, guide posts 72, connecting holes 71, and adhesive rods 9 are in one-to-one correspondence. That is, when the diamond-forming substrate 91 on the adhesive rod 9 that has been rotated to the bottom is polished, each guide post 72 is embedded in the corresponding positioning hole 612. At this time, the adhesive rod 9 at the bottom is in a vertical state. Similarly, when the rotating mounting sleeve 7 polishes the diamond-forming substrate 91 on the next adhesive rod 9 that has been rotated to the bottom, each guide post 72 is embedded in the corresponding positioning hole 612. At this time, the adhesive rod 9 at the bottom is still in a vertical state.

[0045] The working principle and process of this embodiment are as follows: Install each component according to the above instructions, and install the base 1 on the worktable near the grinding disc. Adhere each diamond generating substrate 91 to the corresponding adhesive rod 9, and then thread the adhesive rod 9 into the corresponding connection hole 71 on the mounting sleeve 7. In the initial state, under the elastic force of the transverse spring 9, the mounting sleeve 7 abuts against the limiting disc 61, and each guide post 72 is embedded in the corresponding positioning hole 612. At this time, the mounting sleeve 7 cannot rotate, and the adhesive rod 9 at the bottom of the mounting sleeve 7 is in a vertical state. When grinding the diamond generating substrate 91, manually press down the mounting sleeve 7 or the locking block 5 so that the adhesive rod 9 at the bottom of the mounting sleeve 7, the diamond generating substrate 91, and the locking block 5 move downward along the axis of the column 2, so that the diamond generating substrate 91 abuts against the grinding disc, thereby grinding the diamond generating substrate 91. When it is necessary to rotate the mounting sleeve 7 to check the polishing effect of the cut surface of the freshly polished diamond-forming substrate 91, one can press the locking block 5 with one palm and hold the mounting sleeve 7 with one finger, and move the mounting sleeve 7 toward the locking block 5 to compress the transverse spring 8, so that the guide post 72 disengages from the positioning hole 612. Then the mounting sleeve 7 can be rotated to check the polishing quality of the diamond-forming substrate 91; or one can hold the limiting plate 61 with one hand and pull the mounting sleeve 7 toward the locking block 5 with the other hand, compressing the transverse spring 8 at the same time, so that the guide post 72 disengages from the positioning hole 612. Then the mounting sleeve 7 can be rotated to check the polishing quality of the diamond-forming substrate 91. When grinding is required again, the mounting sleeve 7 is rotated in the opposite direction. Under the action of the transverse spring 8, the guide post 72 re-enters the positioning hole 612 for the next grinding. When polishing the diamond-forming substrate 91 on the next bonding rod 9, the process is similar to rotating the mounting sleeve 7 to check the polishing effect of the cut surface of the newly polished diamond-forming substrate 91. One hand can be pressed against the locking block 5, and the mounting sleeve 7 can be held by the fingers. The mounting sleeve 7 is moved towards the locking block 5, compressing the transverse spring 8, causing the guide post 72 to disengage from the positioning hole 612. Then, the mounting sleeve 7 can be rotated so that the next diamond-forming substrate 91 to be polished is at the bottom. At this point, under the elastic force of the transverse spring 8, the guide post 72 re-enters the positioning hole 612. Alternatively, one hand can hold the limiting plate 61, and the other hand can pull the mounting sleeve 7 towards the locking block 5, compressing the transverse spring 8 and causing the guide post 72 to disengage from the positioning hole 612. Then, the mounting sleeve 7 can be rotated so that the next diamond-forming substrate 91 to be polished is at the bottom. At this point, under the elastic force of the transverse spring 8, the guide post 72 re-enters the positioning hole 612. Afterward, the selected next diamond-forming substrate 91 can be polished. It should be noted that the optimal operating method is to pull the installation sleeve 7 so that the guide post 72 is disengaged from the positioning hole 612 but not disengaged from the guide ring groove 611.
