Description

Technical Field

[0001] The utility model relates to the field of diamond polishing, in particular to a diamond polishing device. Background Art

[0002] Currently, diamond polishing is commonly performed using ion beam sputtering, vacuum plasma chemical polishing, thermochemical polishing, or mechanical processing. Mechanical processing involves directly contacting the diamond surface with a grinding disc coated with diamond micropowder, relying solely on the impact of the two to perform polishing. For details, please refer to the Chinese utility model application ZL201821647234.5 (authorization publication number CN209335350U), filed by the present applicant, for "Multi-station Diamond Grinding Equipment," which discloses a grinding device suitable for grinding thinner diamonds. The polishing process generally requires three steps: first, bonding the diamond to be polished to a clamping device; second, to prevent the adhesive from melting and thus preventing the single-crystal diamond from falling from the clamping rod, the grinding device also utilizes a cooling device to reduce the temperature of the diamond and adhesive on the clamping device during grinding.

[0003] In order to more easily fix the diamond to be polished, the applicant has proposed a clamping fixture as disclosed in Patent No. 202322944092.6, which can complete the two previous processes of bonding and cooling through a single clamping step. However, during the operation stage, the clamping fixture still needs to be manually adjusted to maintain a preset angle between the polishing surface of the diamond to be polished and the polishing surface of the grinding disc. During the entire operation, certain human errors are inevitable, and the process is time-consuming and labor-intensive, with poor timeliness. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a diamond polishing device which can avoid manual adjustment of the polishing surface of the diamond to be polished and the polishing surface of the grinding disc to maintain a preset angle in response to the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above technical problems is as follows: the diamond polishing device includes a fixing seat for fixing the diamond to be polished, and also includes a clamping rod for clamping the diamond to be polished for polishing on the polishing surface of the grinding disc, and the fixing seat is provided with a clamping assembly for clamping the clamping rod, which is characterized by:

[0006] The clamping rod has a first mounting surface for clamping the diamond to be polished, the first mounting surface is perpendicular to the central axis of the clamping rod and parallel to the polishing surface of the diamond to be polished, and the clamping assembly is further provided with a sensor, the second mounting surface of the sensor is perpendicular to the central axis of the clamping rod, so as to obtain position data of the polishing surface;

[0007] It also includes a driving assembly for driving the fixed seat to rotate, and the sensor is also connected to the controller. The controller is configured to control the driving assembly to drive the polishing surface of the diamond to be polished and the polishing surface of the grinding disk to maintain a preset angle relationship based on the position data of the polishing surface and the preset data of the previous grinding disk.

[0008] To enable the clamping assembly to clamp the clamping rod, the clamping assembly preferably includes a clamping seat for placing the clamping rod and a fastener for securing the clamping rod to the clamping seat, with the sensor disposed on the clamping seat. The clamping rod is fixedly connected to the clamping seat via the fastener, and the sensor is disposed on the clamping seat. Thus, the sensor and the diamond to be polished on the clamping rod rotate synchronously with the fixed seat. Because the second mounting surface of the sensor is parallel to the polishing surface of the diamond to be polished, the sensor can obtain real-time position data of the polishing surface.

[0009] To ensure that the second mounting surface of the sensor is parallel to the polishing surface of the diamond being polished, the clamping seat is preferably provided with a clamping slot for the clamping rod to pass through. The clamping slot cooperates with the fastener to clamp the clamping rod, and the second mounting surface of the sensor is perpendicular to the wall of the clamping slot and connected to the clamping seat, thereby being perpendicular to the central axis of the clamping rod. Since the clamping slot is used to adapt to and fasten the clamping rod, it can be understood that the wall of the clamping slot must be parallel to the central axis of the clamping rod, and the second mounting surface of the sensor is perpendicular to the wall of the clamping slot, thereby ensuring that the second mounting surface of the sensor is parallel to the polishing surface of the diamond being polished.

[0010] Furthermore, to enable the sensor to be mounted on the clamping seat, preferably, two walls are extended from both sides of the clamping seat in a direction away from the fixing seat, with the clamping groove formed between the two walls. Correspondingly, the clamping seat further includes a clamping portion with an opening extending toward the clamping groove, with the upper surface of the clamping portion being perpendicular to the wall of the clamping groove, thereby forming a second mounting surface for the sensor. The provision of this clamping portion can, on the one hand, serve as a position limit for the clamping rod, and on the other hand, make the upper surface of the clamping portion perpendicular to the wall of the clamping groove, facilitating the sensor to be mounted on the clamping seat perpendicular to the wall of the clamping groove.

[0011] In order to enable the fastener to clamp the clamping rod, the clamping portion preferably includes a crossbar located on the other side of the clamping rod relative to the clamping groove. Both ends of the crossbar extend toward the clamping groove to form connecting rods connected to the wall of the clamping groove. The fastener is disposed on the crossbar and can move toward the clamping rod to clamp the clamping rod. This design allows the fastener to apply force to the clamping rod using the crossbar as a fulcrum, thereby securing the clamping rod between the crossbar and the clamping groove.

[0012] To prevent the diamond being polished from falling off due to excessive temperatures in the clamping rod, the upper end of the clamping seat preferably further comprises an inlet and an outlet adjacent to the clamping groove. The inlet and outlet communicate with each other to form a flow channel for cooling the clamping rod. This flow channel is provided in consideration of the fact that the diamond being polished is typically secured to the clamping rod via adhesive, and that the temperature of the clamping rod rises during the polishing process. Excessive temperatures could cause the diamond to fall off the surface of the clamping rod.

[0013] To enable the drive assembly to drive the fixed base to rotate, the drive assembly preferably includes a first rotating portion capable of driving the fixed base to rotate along the X-axis, and a second rotating portion capable of rotating along the Y-axis. The first rotating portion is interleaved with the second rotating portion, thereby rotating with the second rotating portion. Enabling the fixed base to rotate about both the X-axis and the Y-axis allows adjustment of the angular relationship between the polishing surface of the diamond to be polished and the polishing surface of the grinding disc.

[0014] In order to enable the drive assembly to drive the fixed seat to move for polishing, preferably, the drive assembly further includes a first movable portion capable of moving along the Z-axis direction, the first movable portion being connected to the second rotating portion so as to move together with the second rotating portion, and a second movable portion capable of moving along the Y-axis direction, with the first movable portion being staggered on the second movable portion so as to move with the second movable portion. The purpose of enabling the fixed seat to move along the Z-axis direction is to adjust the distance and grinding force between the polishing surface of the diamond to be polished and the polishing surface of the grinding disc, while the purpose of enabling the fixed seat to move along the Y-axis direction is to fully grind the diamond to be polished. In addition, the reason why the fixed seat does not need to be able to move along the X-axis direction is that the rotation of the grinding disc is similar to causing the fixed seat to move relative to the grinding disc along the X-axis direction.

[0015] Compared with the prior art, the advantages of the present invention are: by making the second mounting surface of the sensor parallel to the first mounting surface on which the diamond to be polished is mounted, the second mounting surface of the sensor is further made parallel to the polishing surface of the diamond to be polished, and the sensor is arranged on the clamping assembly, so that it can rotate synchronously with the diamond to be polished under the action of the driving assembly, thereby obtaining the position data of the surface to be polished in real time, and cooperating with the controller to control the driving assembly so that the polishing surface of the diamond to be polished and the polishing surface of the grinding disk maintain a preset angle relationship, with higher accuracy and efficiency.

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 9 The above is a preferred embodiment of the present invention. Figures 1-2The diamond polishing device in this embodiment includes a fixed base 1 for fixing a diamond A to be polished, and a clamping rod 11 for clamping the diamond A to be polished for polishing on the polishing surface N of the grinding wheel T. The fixed base 1 is provided with a clamping assembly 3 for clamping the clamping rod 11. The clamping rod 11 has a first mounting surface p1 for clamping the diamond A to be polished. The first mounting surface p1 is perpendicular to the central axis C of the clamping rod 11 and parallel to the polishing surface M of the diamond A to be polished. The clamping assembly 3 is also provided with a sensor 4. The second mounting surface p2 of the sensor 4 is perpendicular to the central axis C of the clamping rod 11 to obtain position data of the polishing surface M. In addition, the diamond polishing device also includes a drive assembly 2 for driving the fixed base 1 to rotate, and the sensor 4 is also connected to the controller. The controller is configured to control the drive assembly 2 to drive the polishing surface M of the diamond A to be polished and the polishing surface N of the grinding disk T to maintain a preset angle relationship based on the position data of the polishing surface M and the preset data of the previous grinding disk T.

[0027] How does the clamping assembly 3 realize the clamping function of the clamping rod 11? Figures 2-3 As shown, the clamping assembly 3 includes a clamping seat 31 for placing the clamping rod 11 and a fastener 32 for fastening the clamping rod 11 to the clamping seat 31. The sensor 4 is disposed on the clamping seat 31. The clamping rod 11 is fixedly connected to the clamping seat 31 via the fastener 32, and the sensor 4 is disposed on the clamping seat 31. Therefore, the sensor 4 and the diamond A to be polished on the clamping rod 11 can rotate synchronously with the fixed seat 1. Because the second mounting surface p2 of the sensor 4 is parallel to the polishing surface M of the diamond A to be polished, the sensor 4 can obtain real-time position data of the polishing surface M. The clamping seat 31 is provided with a clamping groove 311 for the clamping rod 11 to pass through. The clamping groove 311 cooperates with the fastener 32 to clamp the clamping rod 11. The second mounting surface p2 of the sensor 4 is perpendicular to the wall of the clamping groove 311 and is connected to the clamping seat 31, thereby being perpendicular to the central axis C of the clamping rod 11. Since the clamping groove 311 is used to adapt to and fasten the clamping rod 11, it can be understood that the wall of the clamping groove 311 must be parallel to the central axis C of the clamping rod 11, and the second mounting surface p2 of the sensor 4 is perpendicular to the wall of the clamping groove 311, thereby ensuring that the second mounting surface p2 of the sensor 4 is parallel to the polishing surface M of the diamond A to be polished.

[0028] Furthermore, regarding the specific structure of the clamping seat 31, two walls extend from both sides of the clamping seat 31 in the direction away from the fixing seat 1, forming a clamping groove 311 between the two walls. Correspondingly, the clamping seat 31 also includes a clamping portion 312 with an opening extending toward the clamping groove 311. The upper surface of the clamping portion 312 is perpendicular to the walls of the clamping groove 311, thereby forming a second mounting surface p2 for the sensor 4. The provision of the clamping portion 312 not only allows the clamping groove 311 and the opening of the clamping portion 312 to face each other, thereby circumferentially surrounding the clamping rod 11 and limiting the clamping rod 11; it also allows the upper surface of the clamping portion 312 to be perpendicular to the walls of the clamping groove 311, facilitating the installation of the sensor 4 on the clamping seat 31 perpendicular to the walls of the clamping groove 311. The clamping portion 312 includes a crossbar 313 located on the other side of the clamping rod 11 relative to the clamping groove 311. Both ends of the crossbar 313 extend toward the clamping groove 311 to form a connecting rod 314 connected to the wall of the clamping groove 311. The fastener 32 is provided on the crossbar 313 and can move toward the clamping rod 11 to clamp the clamping rod 11. The fastener 32 in this embodiment is a bolt. A threaded hole for the bolt to pass through is provided on the crossbar 313, so that the bolt can apply a force to the clamping rod 11 with the crossbar 313 as a fulcrum, thereby fixing the clamping rod 11 between the crossbar 313 and the clamping groove 311. Figure 4 As shown, the upper end of the clamping seat 31 further includes an inlet 315 and an outlet 316 adjacent to the clamping groove 311. The inlet 315 and the outlet 316 communicate with each other to form a flow channel 317 for cooling the clamping rod 11. The flow channel 317 is provided to account for the fact that the diamond A to be polished is typically secured to the clamping rod 11 with an adhesive. Furthermore, the temperature of the clamping rod 11 rises during the polishing process. Excessive temperature increases can cause the diamond A to be polished to fall off the surface of the clamping rod 11.

[0029] Finally, regarding the specific structure of the drive assembly 3, the drive assembly 3 includes a first rotating portion 21 capable of driving the fixed base 1 to rotate along the X-axis direction, and a second rotating portion 22 capable of rotating along the Y-axis direction. The first rotating portion 21 is interleaved with the second rotating portion 22, thereby rotating with the second rotating portion 22. Enabling the fixed base 1 to rotate about the X-axis and Y-axis directions allows adjustment of the angular relationship between the polishing surface M of the diamond A to be polished and the polishing surface N of the grinding wheel T. The drive assembly 2 also includes a first movable portion 23 capable of moving along the Z-axis direction. The first movable portion 23 is connected to the second rotating portion 22 and moves along with it. It also includes a second movable portion 24 capable of moving along the Y-axis direction. The first movable portion 23 is interleaved with the second movable portion 24, thereby moving with it. The purpose of enabling the fixed seat 1 to move along the Z-axis direction is to adjust the distance between the polishing surface M of the diamond A to be polished and the polishing surface N of the grinding wheel T and the grinding force, while the purpose of enabling the fixed seat 1 to move along the Y-axis direction is to fully grind the diamond A to be polished. In addition, the reason why the fixed seat 1 does not need to be able to move along the X-axis direction is that the rotation of the grinding wheel T is similar to the fixed seat 1 relative to the grinding wheel T along the X-axis direction.

[0030] The following is a specific usage process of the drive component 2 in this embodiment:

[0031] like Figure 5 As shown, the fixing seat 1 is in the initial state at this time; Figure 6 As shown, compared with the initial state, the fixing seat 1 is in a state of rotating around the X axis under the action of the first rotating portion 21; see Figure 7 , the second rotating part 22 can drive the first rotating part 21 and the fixed base 1 to rotate together around the Y axis. At this point, the driving component 2 has the ability to adjust the angle relationship between the polishing surface M and the polishing surface N; Figure 8 As shown, a first moving portion 23 is further provided in front of the second rotating portion 22 along the Y axis direction, and the fixing seat 1 can be moved up and down along the Z axis under the action of the first moving portion 23; finally, as shown Figure 9 As shown, the first moving portion 23 is also connected to the second moving portion 24, so that the fixing base 1 can move along the Y-axis direction.
