[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0030] like Figures 1 to 4 As shown, the embodiment relates to a deep-hole crystal polishing head, including: a grinding shank 11, a grinding disc 12, and polishing pads 13. The grinding disc 12 and the grinding shank 11 are fixedly connected, and the grinding disc 12 is provided with a plurality of mounting slots 121 spaced apart along the circumference. Multiple sets of polishing pads 13 are provided, and the multiple sets of polishing pads 13 and the multiple mounting slots 121 are arranged in a one-to-one correspondence. The polishing pads 13 are detachably installed in the mounting slots 121.

[0031] The deep-hole crystal polishing head using the technical solution of this embodiment includes: a grinding shank 11, a grinding disc 12, and polishing pads 13. The grinding disc 12 and the grinding shank 11 are fixedly connected. The grinding shank 11 can drive the grinding disc 12 to rotate, and the fixed connection makes the grinding disc 12 more stable during rotation. The grinding disc 12 is provided with multiple mounting slots 121 at intervals along its circumference. Multiple sets of polishing pads 13 are provided, with each set corresponding to a different mounting slot 121. The polishing pads 13 are detachably installed in the mounting slots 121. The polishing pads 13 can rotate synchronously with the grinding disc 12 to polish the deep-hole crystal 100. Furthermore, the polishing pads 13 can be individually disassembled and replaced, eliminating the need to replace the entire deep-hole crystal polishing head, thus simplifying installation and saving costs. The technical solution of this embodiment effectively solves the problem of instability during rotation of the polishing head in the prior art.

[0032] like Figure 1 , Figure 2 and Figure 5As shown, in the technical solution of Embodiment 1, the polishing abrasive disc 13 has a first mating groove 131 and a second mating groove 132, which are respectively disposed on opposite side surfaces of the polishing abrasive disc 13. The distance between the first mating groove 131 and the second mating groove 132 is greater than or equal to the length of the mounting groove 121. The polishing abrasive disc 13 has a first locking protrusion 133 and a second locking protrusion 134, both of which are located close to the grinding disc 12. When the first locking protrusion 133 and the second locking protrusion 134 are inserted into the mounting groove 121, both protrusions abut against the inner wall of the grinding disc 12, and the first mating groove 131 and the second mating groove 132 abut against the side wall of the mounting groove 121, thereby achieving a tight connection between the polishing abrasive disc 13 and the mounting groove 121.

[0033] It should be noted that the polishing pad 13 is made of synthetic fiber. When the polishing pad 13 is inserted into the mounting slot 121, the polishing pad 13 undergoes elastic deformation to facilitate insertion. After insertion, as the polishing pad 13 returns to its original shape, both the first mating slot 131 and the second mating slot 132 abut against the side wall of the mounting slot 121, achieving a tight connection.

[0034] It should also be noted that as the polishing disc 13 rotates, under the action of centrifugal force, the force between the first locking protrusion 133 and the second locking protrusion 134 and the inner wall of the grinding disc 12 increases. Therefore, during the polishing process, even if the polishing disc 13 has a strong force with the deep hole crystal 100, the polishing disc 13 is not easy to separate from the grinding disc 12.

[0035] like Figure 1 As shown, in the technical solution of Embodiment 1, the side of the polishing pad 13 away from the grinding disk 12 is rectangular. The side of the polishing pad 13 away from the grinding disk 12 is the side with the largest contact area with the deep hole crystal 100. The length of the rectangle is greater than the distance between the first mating groove 131 and the second mating groove 132. This makes the polishing area larger when polishing the deep hole crystal 100, and can better cover the deep hole crystal.

[0036] like Figure 4 As shown, in the technical solution of Embodiment 1, multiple mounting slots 121 are opened along the axial direction of the grinding disc 12, so that the extension direction of the polishing grinding disc 13 can better correspond to the extension direction of the deep hole crystal, thereby facilitating polishing.

[0037] like Figure 1 As shown, in the technical solution of Embodiment 1, the diameter of the grinding disc 12 is larger than the diameter of the grinding shank 11. This arrangement makes the weight of the grinding disc 12 greater than the weight of the grinding shank 11, so that when polishing the deep-hole crystal 100, the grinding disc 12 will not shake violently and affect the polishing effect.

[0038] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the grinding shank 11 has a first through hole 111, and the grinding disc 12 has a second through hole 122, with the first through hole 111 and the second through hole 122 connected together. The first through hole 111 and the second through hole 122 are provided to facilitate the outflow of polishing fluid.

[0039] This embodiment also provides a CNC polishing device, in which a deep-hole crystal polishing head is mounted.

[0040] In the technical solution of Embodiment 1, the CNC polishing equipment includes a base, a support frame, a polishing platform, a polishing platform drive mechanism, a pneumatic gripper, and a pneumatic gripper drive mechanism. The support frame is mounted on the base, and the support frame and the base are vertically arranged. The polishing platform drive mechanism is mounted on the base and is connected to the polishing platform via a transmission connection. The polishing platform drive mechanism provides driving force to make the polishing platform rotate. The pneumatic gripper drive mechanism is mounted on the support frame and is connected to the pneumatic gripper via a transmission connection. The pneumatic gripper drive mechanism provides driving force to make the pneumatic gripper rotate. The pneumatic gripper clamps the grinding shank 11, causing the grinding shank 11 to rotate synchronously. The polishing platform can be selectively controlled to rotate. During use, the deep-hole crystal 100 is placed on the polishing platform, and the polishing platform is provided with limit protrusions for limiting the deep-hole crystal 100.

[0041] It should be noted that the polishing platform drive mechanism includes a first geared motor and a first coupling. The polishing platform has a mating shaft at its bottom. The first geared motor is mounted on the base, and its drive shaft is connected to the mating shaft via the first coupling. The rotation of the polishing platform is achieved by driving the first geared motor. The pneumatic gripper drive mechanism is a rotary cylinder, mounted on a support frame. The rotary cylinder and the rotating shaft of the pneumatic gripper cooperate to achieve the rotation of the pneumatic gripper.

[0042] In the technical solution of Embodiment 1, the CNC polishing equipment also includes a liquid inlet pipe, which is correspondingly arranged with the grinding handle 11 and the grinding disc 12. The liquid inlet pipe is used to deliver polishing fluid, which can improve the polishing accuracy of the deep hole crystal 100, making the surface of the deep hole crystal 100 smoother, and at the same time absorb the heat generated during the polishing process.

[0043] like Figure 6 and Figure 7As shown, the difference between the technical solution of Embodiment 2 and Embodiment 1 is that the deep hole crystal polishing head further includes a mounting plate 14. Multiple polishing discs 13 are spaced apart circumferentially along the mounting plate 14, and both the polishing discs 13 and the mounting plate 14 are fixedly connected. The mounting plate 14 has multiple fixing slots 141, which are sequentially placed between adjacent polishing discs 13. Multiple sets of fixing strips 123 are arranged on the outer circumferential side of the grinding plate 12. These fixing strips 123 and fixing slots 141 are arranged in a one-to-one correspondence to fix the discs. The retaining strips 123 are inserted into the fixing slots 141. Multiple sets of retaining strips 123 are made of rubber or synthetic fiber, allowing for elastic deformation. Both ends of the retaining strips 123 have retaining protrusions. The length of the retaining strips 123 is greater than or equal to the length of the fixing slots 141. Therefore, after inserting the retaining strips 123 into the fixing slots 141, they abut against the inner wall of the fixing slots 141, while the retaining protrusions abut against the outer wall of the fixing slots 141, thus connecting the mounting plate 14 and the grinding plate 12. The width of the retaining strips 123 is less than the width of the polishing pad 13, ensuring that the retaining strips 123 do not affect the polishing of the polishing pad 13. The design of Embodiment Two allows all polishing pads 13 to be removed and replaced during replacement, thereby significantly improving efficiency.
