Description

Technical Field

[0001] This invention relates to the field of artificial diamond cutting technology, specifically to a clamping fixture for artificial diamond cutting. Background Technology

[0002] In the jewelry industry, synthetic diamonds offer consumers more diverse and cost-effective options, satisfying the pursuit of beauty and quality among different consumer groups. In industrial manufacturing, their high hardness and wear resistance make them ideal materials for manufacturing high-performance cutting tools and wear-resistant parts. In the semiconductor industry, the unique electrical and thermal properties of synthetic diamonds bring new possibilities for developing next-generation high-performance electronic devices. The rapid development of the synthetic diamond industry has also placed higher demands on the cutting and processing stages. Cutting, as a key process in synthetic diamond processing, directly affects the final quality and market value of the diamond. Clamping fixtures, as an important component of cutting equipment, play a crucial role in the precision, efficiency, and yield of the cut diamonds.

[0003] Traditional diamond cutting fixtures are often simple in design, employing a single clamping method such as mechanical grippers or vacuum suction. These fixtures typically lack flexibility and adjustability, often only suitable for diamonds of specific sizes and shapes, failing to meet diverse production needs. Frequent fixture changes are required when processing diamonds of different sizes, increasing production costs and time, and reducing efficiency. Summary of the Invention

Each slider has an adjusting block fixedly installed on its top, each adjusting block has a sliding rod fixedly installed on its top, each sliding rod has a bent sliding rod fixedly installed on its top, each bent sliding rod has an inner sleeve fixedly installed on its top, each inner sleeve has an outer rotating sleeve rotatably installed on its outer side, and each outer rotating sleeve has a clamping disc fixedly installed on its top.

[0008] Preferably, the top of the threaded rod is rotatably mounted to the bottom of the drive platform, and limit moving grooves are provided on both sides of the inner cavity of the mounting cover. Limit moving strips are fixedly installed on both sides of the drive platform, and the end of the limit moving strip away from the drive platform is slidably mounted on the inner side of the limit moving groove.

[0009] Preferably, the guide cover has three adjustment slots inside, the end of the adjustment block away from the slider is slidably installed on the inner side of the adjustment slot, and a sealing plate is fixedly installed on the top of the guide cover.

[0010] Preferably, the sealing disc has three sliding grooves 1 inside, and three sliding rods are slidably installed on the inner side of the three sliding grooves 1 respectively. The moving disc has three sliding grooves 2 inside, and the three bent sliding rods are slidably installed on the inner side of the three sliding grooves 2 respectively.

[0011] Preferably, a protective cover is fixedly installed at the bottom of the mounting cover, a mounting plate is fixedly installed inside the protective cover, the top of the drive motor is fixedly connected to the bottom of the mounting plate, a connecting plate is fixedly installed at the end of the protective cover away from the mounting cover, and the connecting plate is fixedly installed on the top of the mounting base plate.

[0012] Preferably, each of the three adjusting blocks has a rotating gear rotatably mounted inside, and each of the sliding rods has a transmission rod rotatably mounted inside. The top of the transmission rod and the bottom of the outer rotating sleeve are both fixedly mounted with a transmission wheel.

[0013] Preferably, a transmission rod 2 is rotatably installed inside each of the bent slide rods, and two transmission wheels 2 are fixedly installed on the outer side of the transmission rod 2. A transmission belt is sleeved on the outer side of the transmission wheel 1 and the transmission wheel 2, and the bottom of the transmission rod 1 is fixedly connected to the top of the rotating gear.

[0016] Additionally, when the adjusting block moves on top of the drive platform, it can rotate the clamping disc, thereby causing the high-temperature resistant pad on the outside of the clamping disc to rotate. The high-temperature resistant pad is equipped with conical heads on its outside, and the density of the conical heads increases proportionally and gradually. When the three clamping discs are furthest apart, the density of the conical heads on the outside of the high-temperature resistant pad is the lowest, which can increase the contact area with larger-sized artificial diamonds and provide a more stable clamping force, making it easier to firmly clamp larger-sized artificial diamonds. When the three clamping discs are closest together, the density of the conical heads on the outside of the high-temperature resistant pad is the highest, which can better adapt to the shape of smaller-sized artificial diamonds and make it easier to firmly clamp smaller-sized artificial diamonds.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-6 The present invention provides a technical solution: a clamping fixture for artificial diamond cutting, comprising a mounting base plate 1 and a mounting cover 2. A telescopic placement component is mounted on the top of the mounting base plate 1. A guide cover 5 is fixedly mounted on the top of the mounting cover 2. An adjusting clamping component is installed inside the mounting cover 2 and the guide cover 5. An internal threaded ring 21 is fixedly mounted on the bottom of the mounting cover 2. A threaded rod 28 is threadedly connected inside the internal threaded ring 21. A cross slide rod 19 is slidably mounted inside the threaded rod 28. A rotating column 18 is fixedly mounted on the bottom of the cross slide rod 19. A drive motor 16 is fixedly mounted on the end of the rotating column 18 away from the cross slide rod 19.

[0026] The working principle of the above technical solution is as follows: First, the artificial diamond to be processed is placed on top of the telescopic placement assembly. Then, the drive motor 16 is started. The output end of the drive motor 16 can drive the rotating column 18 to rotate, which in turn drives the cross slide bar 19 to rotate and the threaded rod 28 to rotate. With the cooperation of the internal threaded ring 21, the threaded rod 28 can rotate and move up and down inside the internal threaded ring 21, thereby pushing the adjusting clamping assembly to move inside the mounting cover 2 and the guide cover 5, thereby adjusting the relative position of the three clamping discs 12, thus clamping the artificial diamond to be processed, which is convenient for subsequent cutting and processing, and also convenient for clamping artificial diamonds of different sizes, improving the use effect of the device.

[0027] In another implementation scheme, such as Figures 1-6 As shown, the telescopic placement assembly includes three telescopic rods 8, the bottoms of which are fixedly connected to the top of the mounting base plate 1. A movable disk 14 is fixedly installed on the top of the three telescopic rods 8, and a placement platform 13 is fixedly installed on the top of the movable disk 14. The adjusting clamping assembly includes a limiting moving groove 23, the top of which has three sliding grooves 29. A slider 30 is slidably installed inside each of the three sliding grooves 29. An adjusting block 24 is fixedly installed on the top of each slider 30. A sliding rod 10 is fixedly installed on the top of each adjusting block 24. A bent sliding rod 15 is fixedly installed on the top of each sliding rod 10. An inner sleeve post 31 is fixedly installed on the top of each bent sliding rod 15. An outer rotating sleeve 32 is rotatably installed on the outside of each inner sleeve post 31. A clamping disk 12 is fixedly installed on the top of each outer rotating sleeve 32. The top of the threaded rod 28 is rotatably installed to the bottom of the drive platform 22. Limiting moving grooves 23 are provided on both sides of the inner cavity of the mounting cover 2. Limiting moving strips 20 are fixedly installed on both sides of the drive platform 22. The end of the limiting moving strip 20 away from the drive platform 22 is slidably installed inside the limiting moving groove 23. Three adjusting grooves 27 are opened inside the guide cover 5. The end of the adjusting block 24 away from the slider 30 is slidably installed inside the adjusting groove 27. A sealing plate 9 is fixedly installed on the top of the guide cover 5. Three sliding grooves 6 are opened inside the sealing plate 9. Three sliding rods 10 are slidably installed inside the three sliding grooves 6 respectively. Three sliding grooves 7 are opened inside the moving plate 14. Three bent sliding rods 15 are slidably installed inside the three sliding grooves 7 respectively. A protective cover 3 is fixedly installed at the bottom of the mounting cover 2. A mounting plate 17 is fixedly installed inside the protective cover 3. The top of the drive motor 16 is fixedly connected to the bottom of the mounting plate 17. A connecting plate 4 is fixedly installed at the end of the protective cover 3 away from the mounting cover 2. The connecting plate 4 is fixedly installed on the top of the mounting base plate 1.

[0028] When the threaded rod 28 rotates and moves up and down, with the cooperation of the limiting moving strip 20 and the limiting moving groove 23, it can drive the drive table 22 to move up and down, thereby driving one end of the three adjusting blocks 24 to move inside the adjusting groove 27, so that the ends of the three adjusting blocks 24 away from the adjusting groove 27 move closer or further away from each other, thereby causing the three sliding rods 10 to move closer or further away from each other inside the three sliding grooves 1 6, and causing the three bent sliding rods 15 to move inside the three sliding grooves 2 7, and driving the clamping plates 12 to move closer or further away from each other, so that the three clamping plates 12 can clamp the diamond to be processed. In addition, when the bent sliding rods 15 move, they can drive the moving plate 14 to move up and down, and cause the three telescopic rods 8 to extend and retract, so that the relative height of the clamping plate 12 and the moving plate 14 is consistent, thereby facilitating the clamping plate 12 to clamp the artificial diamond placed on the top of the placement table 13.

[0029] In another implementation scheme, such as Figures 1-6As shown, rotating gears 26 are rotatably installed inside the three adjusting blocks 24. Transmission rod 33 is rotatably installed inside the sliding rod 10. Transmission wheel 34 is fixedly installed on the top of transmission rod 33 and the bottom of outer rotating sleeve 32. Transmission rod 36 is rotatably installed inside the bent sliding rod 15. Two transmission wheels 37 are fixedly installed on the outside of transmission rod 36. Transmission belt 35 is sleeved on the outside of transmission wheel 34 and transmission wheel 37. The bottom of transmission rod 33 is fixedly connected to the top of rotating gear 26. Three racks 25 are fixedly installed on the top of drive platform 22, and the three rotating gears 26 mesh with the three racks 25 respectively. High temperature resistant pads 11 are fixedly installed on the outside of clamping plate 12. Conical heads are fixedly installed on the outside of high temperature resistant pads 11.

[0030] When the adjusting block 24 moves on top of the drive platform 22, the rotating gear 26 can move to one side of the rack 25, causing the rack 25 to rotate. This drives the transmission rod 33 to rotate, which in turn drives one of the transmission wheels 34 to rotate. Through the transmission belt 35, transmission wheel 37, and transmission rod 36, the other transmission wheel 34 rotates, causing the clamping disc 12 to rotate. This, in turn, causes the high-temperature resistant pad 11 on the outer side of the clamping disc 12 to rotate. The high-temperature pad 11 is equipped with tapered heads, and the density of the tapered heads increases proportionally. When the three clamping discs 12 are farthest apart, the tapered head density on the outer side of the high-temperature pad 11 is the lowest, which can increase the contact area with larger artificial diamonds and provide a more stable clamping force, making it easier to firmly clamp larger artificial diamonds. When the three clamping discs 12 are closest together, the tapered head density on the outer side of the high-temperature pad 11 is the highest, which can better adapt to the shape of smaller artificial diamonds and make it easier to firmly clamp smaller artificial diamonds.

[0031] Working principle: First, the synthetic diamond to be processed is placed on top of the telescopic placement assembly. Then, the drive motor 16 is started. The output end of the drive motor 16 drives the rotating column 18 to rotate, which in turn drives the cross slide bar 19 to rotate, and then drives the threaded rod 28 to rotate. With the cooperation of the internal threaded ring 21, the threaded rod 28 can rotate and move up and down inside the internal threaded ring 21, thereby pushing the adjusting clamping assembly to move inside the mounting cover 2 and the guide cover 5, thereby adjusting the relative position of the three clamping discs 12, thus clamping the synthetic diamond to be processed, facilitating subsequent cutting and processing, and also facilitating the processing of synthetic diamonds of different sizes. The diamond is clamped, improving the efficiency of the lifting device. When the threaded rod 28 rotates and moves up and down, in conjunction with the limiting moving strip 20 and the limiting moving groove 23, it drives the drive table 22 to move up and down. This causes one end of the three adjusting blocks 24 to move inside the adjusting groove 27, making the ends of the three adjusting blocks 24 away from the adjusting groove 27 move closer or further apart. This causes the three sliding rods 10 to move closer or further apart inside the three sliding grooves 6, and the three bent sliding rods 15 to move inside the three sliding grooves 7. Furthermore, this causes the clamping discs 12 to move closer or further apart, thus clamping the diamond to be processed. Additionally, when the bending slide bar 15 moves, it can drive the moving disk 14 to move up and down, and cause the three telescopic rods 8 to extend and retract, so that the relative height of the clamping disk 12 and the moving disk 14 remains consistent. This facilitates the clamping disk 12 in clamping the artificial diamond placed on top of the placement platform 13. When the adjusting block 24 moves on top of the drive platform 22, the rotating gear 26 can move on one side of the rack 25, causing the rack 25 to rotate. This, in turn, drives the transmission rod 33 to rotate, thereby driving one of the transmission wheels 34 to rotate. And through the transmission belt 35, the second transmission wheel 37, and the second transmission rod 36, the other transmission wheel 34 is driven to rotate. This causes the clamping disc 12 to rotate, which in turn causes the high-temperature resistant pad 11 on the outside of the clamping disc 12 to rotate. The high-temperature resistant pad 11 has conical heads installed on its outer side, and the density of the conical heads increases proportionally. When the three clamping discs 12 are furthest apart, the density of the conical heads on the outside of the high-temperature resistant pad 11 is the lowest, which can increase the contact area with larger-sized artificial diamonds and provide a more stable clamping force, making it easier to firmly clamp larger-sized artificial diamonds. When the three clamping discs 12 are closest together, the density of the conical heads on the outside of the high-temperature resistant pad 11 is the highest, which can better adapt to the shape of smaller-sized artificial diamonds, making it easier to firmly clamp smaller-sized artificial diamonds.
