Description

Technical Field

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

[0002] Diamond has properties such as high hardness, high compressive strength, good thermal conductivity and wear resistance. Tools made of diamond can achieve high machining accuracy and efficiency in high-speed cutting. Due to the high hardness of diamond, the polishing discs used for polishing are required to meet high requirements when making finished products.

[0003] During diamond polishing, the polishing disc is typically placed horizontally, and the diamond is held in place by a clamping assembly. The diamond is then placed against the surface of the polishing disc, and a downward pressure is applied to the disc to accelerate the polishing process. During polishing, small debris from the diamond easily adheres to the surface of the polishing disc. Because the disc is horizontal, even spraying polishing fluid onto the contact area between the diamond and the disc cannot completely remove all the debris. This residue can cause secondary scratching on the diamond's polished surface, reducing the polishing precision.

[0004] Therefore, how to design a debris removal device to clean up debris on the polishing pad and improve the precision of diamond polishing has become a technical problem that urgently needs to be solved by those in the field. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this utility model is to provide a diamond polishing debris treatment device to solve the problem that the debris is difficult to clean when it is adsorbed on the polishing disc.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A diamond polishing debris treatment device includes a polishing assembly for polishing diamonds and a drive mechanism for rotating the polishing assembly. The polishing assembly includes a vertically arranged polishing disc. During polishing, the diamond abuts against the polishing surface of the polishing disc. The device also includes a spray assembly located on the side of the polishing disc and spraying cleaning fluid onto the polishing surface of the disc. The spray assembly is located upstream of the contact point between the diamond and the polishing disc. A filter box for collecting debris and cleaning fluid is provided directly below the polishing assembly. The spray assembly includes a spray main pipe and several spray nozzles.

[0008] Furthermore, the spray assembly is located at the bottom of the side of the polishing disc, and the main spray pipe is located in the YZ plane and is inclined. The axis of the main spray pipe forms an angle α with the Z axis, wherein the angle α is between 0° and 30°.

[0009] Furthermore, the polishing surface of the polishing disc is provided with a plurality of drainage grooves that are evenly distributed in a circumferential direction.

[0010] Furthermore, the polishing assembly includes a positioning disk with a positioning area on it, and the positioning area is fixedly connected to the positioning disk by positioning bolts.

[0015] Furthermore, it also includes a circulation assembly, which includes a circulation pump, a suction pipe, and a delivery pipe. The circulation pump is fixedly installed on the impurity filter box. One end of the suction pipe is connected to the inlet end of the circulation pump, and the other end of the suction pipe is located in the second filter chamber and below the liquid surface of the cleaning liquid. One end of the delivery pipe is connected to the outlet end of the circulation pump, and the other end of the delivery pipe is connected to the main spray pipe.

[0016] Furthermore, the spray assembly also includes a positioning seat and a positioning clamp. The main spray pipe is fixed to the positioning seat by the positioning clamp.

[0023] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This embodiment provides a diamond polishing debris treatment device, which mainly cleans the debris remaining on the polishing pad, reduces the risk of secondary scratching of the diamond polishing surface, and improves the polishing accuracy of the diamond.

[0025] For ease of understanding, the direction is redefined in this embodiment, as follows: Figure 1 As shown, refer to Figure 1 The three-axis coordinate system in the diagram uses the plane formed by XY as the horizontal plane and the plane formed by YZ as the vertical plane.

[0026] like Figure 1 and Figure 2 As shown, the device includes a polishing assembly 1 for polishing diamond 3 and a drive mechanism 2 for driving the polishing assembly 1 to rotate. The polishing assembly 1 includes a polishing disk 12 disposed in a vertical plane. The axis of the polishing disk 12 coincides with the X-axis. During polishing, the diamond 3 is clamped by a clamping device, and then the polishing surface of the diamond 3 is put into contact with the polishing surface of the polishing disk 12. A pressure is applied to the polishing disk 12 by the diamond 3 to accelerate the polishing speed of the diamond 3.

[0027] With the above settings, the polishing disk 12 in the polishing assembly 1 is rotated by the drive mechanism 2. Since the diamond 3 abuts against the polishing disk 12, the diamond 3 and the polishing disk 12 move relative to each other, thereby enabling the diamond 3 to be polished.

[0028] It is worth noting that the polishing disk 12 is annular.

[0029] During the polishing process of diamond 3, the point of contact between diamond 3 and polishing disk 12 is deviated from the axis of polishing disk 12. If polishing disk 12 rotates during the polishing process and diamond 3 does not rotate, several uneven concentric scratches are likely to appear on the polished surface of diamond 3. Therefore, in this embodiment, a rotation mechanism for driving diamond 3 to rotate is also included to ensure that diamond 3 can rotate and avoid the appearance of concentric scratches. It is worth noting that at this time, the axis of rotation of diamond is parallel to the axis of polishing disk 12.

[0030] In order to enable the diamond 3 to come into contact with the polishing disk 12 and apply a force along the X-axis to the polishing disk 12, this embodiment also includes a telescopic mechanism that moves the diamond 3 and the clamping device for clamping the diamond 3 along the X-axis. The telescopic mechanism can change the magnitude of the extrusion force between the diamond 3 and the polishing disk 12.

[0031] In this embodiment, to remove residual debris from the polishing disc 12 during polishing of the diamond 3, as follows: Figure 1 and Figure 2 As shown, it also includes a spray assembly 4 for rinsing the polishing disc 12. Specifically, the spray assembly 4 is located upstream of the contact position between the diamond 3 and the polishing disc 12. When polishing the diamond 3, the spray assembly 4 sprays cleaning fluid onto the polishing disc 12, thereby washing away the debris attached to the polishing disc 12 and reducing the impact of the debris on the polishing of the diamond 3.

[0032] It is worth noting here that, as Figure 2As shown, upstream and downstream are defined, with polishing disk 12 as the axis, along the counterclockwise direction of polishing disk 12, the side of the arrow in the counterclockwise direction is downstream, and the direction of the tail of the arrow in the counterclockwise direction is upstream.

[0033] Since the spray assembly 4 is located on the side of the polishing assembly 1, in order to improve the cleaning effect of debris on the polishing disc 12, in this embodiment, as follows: Figure 4 As shown, the spray assembly 4 includes a spray main pipe 43 and a plurality of spray nozzles 44, wherein the spray nozzles 44 are mounted on the spray main pipe 43, and the water outlet end of the spray nozzles 44 is inclined downward and points towards the polishing disk 12.

[0034] With the above setup, the cleaning fluid is evenly distributed onto the spray nozzles 44 through the spray pipe 43. The spray nozzles 44 spray the cleaning fluid under high pressure, impacting the debris on the polishing disc 12 and blowing the debris off the polishing disc 12.

[0035] Since the polishing disc 12 is annular and positioned within a vertical plane, debris blown off the polishing disc 12 can easily fall to other parts of the disc. To reduce the risk of debris falling back onto the polishing disc 12, in this embodiment, as follows... Figure 2 As shown, the spray assembly 4 is positioned on the lower side of the polishing disc 12, so that the debris flies out from the lowest point of the polishing disc 12, preventing the debris from falling back onto the polishing disc 12.

[0036] In order to expand the rinsing range of the cleaning fluid on the polishing disc 12, in this embodiment, such as Figure 2 As shown, the axis of the spray main pipe 43 forms an angle α with the Z-axis, where the angle of α is between 0° and 30°. In this embodiment, the angle of α is 20°, which expands the rinsing range of the polishing disc 12.

[0037] To further reduce the impact of debris on the polishing of diamond 3, in this embodiment, as... Figure 1 and Figure 2 As shown, the polishing surface of the polishing disc 12 is provided with a plurality of circumferentially distributed drainage grooves 121. When the diamond 3 and the polishing disc 12 rub against each other to remove impurities from the diamond 3, the debris formed by the impurities will adhere to the inner wall of the drainage groove 121, reducing the impact of the debris on the polishing of the diamond 3. When the spray assembly 4 cleans the debris on the polishing disc 12, the cleaning liquid is sprayed into the drainage groove 121. The cleaning liquid is sprayed outward along the radial direction of the polishing disc 12 in the drainage groove 121, thereby spraying the debris outward.

[0038] In order to achieve the installation of the polishing disc 12, in this embodiment, as follows: Figure 2 and Figure 3As shown, the polishing assembly 1 also includes a positioning disk 11, wherein the polishing disk 12 is provided with a positioning area 122 near the axis, wherein the positioning area 122 is fixedly connected to the positioning disk 11 by bolts to realize the installation of the polishing disk 12.

[0039] In order to achieve the rotation of the polishing disk 12, in this embodiment, as follows: Figure 3 As shown, it includes a mounting plate 10, wherein a positioning disk 11 is rotatably mounted on the mounting plate 10, and a drive mechanism 2 includes a motor 25 fixedly mounted on the mounting plate 10, as well as a gear ring 23 and a gear 24. The gear ring 23 is fixedly mounted on the positioning disk 11, and the gear 24 is fixedly connected to the output shaft of the motor 25. The gear 24 and the gear ring 23 mesh with each other.

[0040] With the above setup, the motor 25 drives the gear 24 to rotate, which in turn drives the polishing disc 12 to rotate via the gear ring 23 and the positioning disc 11.

[0041] During the polishing process, the diamond 3 needs to apply a pushing force to the polishing disc 12. When the polishing disc 12 and the diamond 3 are in rigid contact, the pushing force from the diamond 3 to the polishing disc 12 can easily increase the resistance to the rotation of the polishing disc 12. In severe cases, the polishing disc 12 may stop rotating. Therefore, in this embodiment, if... Figure 2 and Figure 3 As shown, the drive mechanism 2 also includes a transmission cylinder 21 and several spokes 22. The transmission cylinder 21 is rotatably connected to the mounting plate 10. The several spokes 22 are evenly distributed around the circumference of the transmission cylinder 21. One end of the spokes 22 is fixedly connected to the peripheral wall of the transmission cylinder 21, and the other end of the spokes 22 is fixedly connected to the positioning plate 11. At this time, the gear ring 23 is sleeved on the outside of the transmission cylinder 21 and is fixedly connected to the transmission cylinder 21.

[0042] With the above configuration, since the positioning disk 11 is flexibly connected to the transmission cylinder 21 via the spokes 22, when the diamond 3 pushes the polishing disk 12, the polishing disk 12 tends to move along the X-axis, which can reduce the resistance to the rotation of the polishing disk 12.

[0043] To achieve the installation of the spray assembly 4, in this embodiment, as follows: Figure 3 and Figure 4As shown, the spray assembly 4 also includes a positioning seat 41 and a positioning clamp 42. The spray main pipe 43 is fixed to the positioning seat 41 by the positioning clamp 42. The positioning seat 41 is also provided with a sliding groove 411. The sliding groove 411 is engaged with the edge of the positioning area 122. The positioning area 122 and the sliding groove 411 are slidably connected. Even if the polishing disc 12 tends to move due to the push of the diamond 3, the positioning area 122 and the sliding groove 411 can push the positioning seat 41 to move synchronously, so that the cleaning liquid sprayed by the spray main pipe 43 can be rinsed onto the polishing disc 12.

[0044] To prevent the cleaning fluid sprayed from the spray nozzle 44 from splashing everywhere, in this embodiment, such as Figure 1 and Figure 3 As shown, a filtration box 5 for receiving debris and cleaning fluid is provided directly below the polishing assembly 1. The opening of the filtration box 5 faces upward to receive cleaning fluid containing debris and prevent the cleaning fluid from splashing everywhere.

[0045] In order to filter debris, in this embodiment, such as Figure 3 As shown, the inner cavity of the impurity filter box 5 is provided with a first filter screen 51 that divides the space into a first bearing chamber 501 and a second bearing chamber 502. It is worth noting that the first bearing chamber 501 is located above the second bearing chamber 502. The cleaning liquid sprayed from the spray nozzle 44 carries the debris from the polishing disc 12 and falls onto the first bearing chamber 501. At this time, the first filter screen 51 filters the large particles of debris, leaving the debris above the first filter screen 51. The cleaning liquid and small particles of impurities then fall into the second bearing chamber 502, achieving preliminary filtration of impurities.

[0046] It is worth noting here that, as Figure 3 As shown, the first filter screen 51 is inclined. When debris and cleaning fluid fall into the first bearing cavity 501, or when debris flows with the cleaning fluid to the bottom of the first filter screen 51, the debris is deposited at the bottom of the first filter screen 51. Since the mesh of the first filter screen 51 is relatively fine, the cleaning fluid will accumulate above the first filter screen 51 and slowly penetrate downward into the second bearing cavity 502, thereby improving the separation effect of impurities and cleaning fluid.

[0047] To further filter small particulate impurities in the cleaning solution, in this embodiment, such as Figure 3 As shown, the second bearing cavity 502 is provided with a second filter 52 that divides the second bearing cavity 502 into left and right parts. The second filter 52 is arranged vertically, as shown in the figure. Figure 3As shown, the left side of the second filter screen 52 is the second filter chamber 5022, and the right side of the second filter screen 52 is the first filter chamber 5021. The cleaning liquid accumulated on the first filter screen 51 is located directly above the first filter chamber 5021. At this time, the cleaning liquid in the first carrier cavity 501 flows into the first filter chamber 5021 after being filtered by the first filter screen 51.

[0048] In order to recycle the cleaning solution, in this embodiment, such as Figure 1 and Figure 3 As shown, it also includes a circulation component 6 for conveying the cleaning liquid in the second filter chamber 5022 to the spray component 4, realizing the recycling of the cleaning liquid. At this time, the circulation component 6 includes a circulation pump 61, a suction pipe 62, and a delivery pipe 64. The circulation pump 61 is fixedly installed on the impurity filter box 5. The inlet end of the circulation pump 61 is connected to the suction pipe 62. The other end of the suction pipe 62 is located in the second filter chamber 5022 and below the liquid surface of the cleaning liquid. The outlet end of the circulation pump 61 is connected to the delivery pipe 64. The other end of the delivery pipe 64 is connected to the main spray pipe 43. At this time, the spray component 4 is fixed by the delivery pipe 64 to maintain the stability of the spray component 4.

[0049] With the above setup, as the circulating pump 61 operates, the cleaning liquid in the second filter chamber 5022 is drawn in through the suction pipe 62, and then transported to the spray main pipe 43 through the delivery pipe 64, realizing the recycling of the cleaning liquid. As the cleaning liquid in the second filter chamber 5022 decreases, the cleaning liquid in the first filter chamber 5021 flows into the second filter chamber 5022 after being filtered by the second filter screen 52, replenishing the cleaning liquid in the second filter chamber 5022. At this time, the second filter screen 52 plays the role of filtering small particulate impurities.

[0050] It is worth noting that the mesh count of the second filter 52 is greater than that of the first filter 51.

[0051] To further prevent debris in the cleaning fluid from flowing back into the spray assembly 4, in this embodiment, as follows: Figure 3 As shown, the circulation component 6 also includes a filter 63, which is installed on the delivery pipe 64 to further filter impurities in the cleaning fluid and prevent debris from flowing back to the polishing disc 12 and affecting the polishing effect of the diamond 3.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
