[0052] For ease of explanation, the following embodiments use a scribing and breaking integrated device and a glass production line of this application as an example.

[0053] Example 1

[0054] like Figure 1 As shown, the first aspect of this application provides a double-edge polishing auxiliary device 6 for annular crystal parts, including a support part 1, a first lifting part 2, a second lifting part 3, a mounting part 4, and a drive part 5; the first lifting part 2 and the second lifting part 3 are both liftably mounted on the support part 1, and the second lifting part 3 is spaced apart from the first lifting part 2; the mounting part 4 is in the shape of a retractable long rod, the first end of the mounting part 4 is rotatably connected to the first lifting part 2, and the second end of the mounting part 4 is rotatably connected to the second lifting part 3; the mounting part 4 is provided with opposing first clamping components 41 and second clamping components 42, and a mounting space 43 is formed between the first clamping components 41 and the second clamping components 42, the mounting space 43 being perpendicular to the mounting part 4; the drive part 5 is mounted on the support part 1 and connected to the first lifting part 2; wherein, the drive part 5 drives the first lifting part 2 to reciprocate in the vertical direction, and drives the second end of the mounting part 4 and the second lifting part 3 to reciprocate vertically in opposite directions, so that the mounting part 4 and the first lifting part 2 are at a preset angle.

[0055] Specifically, the support part 1 can be a multi-legged frame, a ring frame, or an open cylindrical shape; the specific form is not limited, as long as it can satisfy the requirement that the first lifting part 2 and the second lifting part 3 can be raised and lowered on the support part 1 and that the drive part 5 can be placed, with the support part 1 providing support. It should be noted that in the polishing equipment provided in this application, the double-edge polishing auxiliary device 6 for the annular crystal part is mounted above the grinding disc 7. Therefore, the support part 1 needs to provide a certain space on the side facing the grinding disc 7 for placing the grinding disc 7. In order to avoid collisions, this arrangement enhances the compactness of the equipment structure and saves space and reduces costs.

[0056] The first lifting part 2 and the second lifting part 3 are both liftable and height-adjustable on the support part 1. The second lifting part 3 is spaced apart from the first lifting part 2. The first lifting part 2 is connected to the drive part 5, and the lifting movement is achieved by the drive part 5. The second lifting part 3 is connected to the first lifting part 2 through a retractable long rod-shaped mounting part 4, so that the second lifting part 3 is driven to lift and lower when the first lifting part 2 lifts and lowers. The first lifting part 2 can be in the form of a linear guide rod 31, a lead screw or lead rod 22, or a kneeling column. The specific form is not limited. The drive part 5 can be a handwheel or rocker arm for manual drive, or a drive motor. The specific form is not limited, as long as the connection between the drive part 5 and the first lifting part 2 can achieve the vertical reciprocating motion of the first lifting part 2.

[0057] Considering that the second lifting part 3 does not need to be connected to the driving part 5, it is driven to lift and lower when the first lifting part 2 lifts and lowers. The second lifting part 3 is connected to the support part 1. The connection between the second lifting part 3 and the support part 1 can be set as a pin hole and pin shaft connection, or as a guide rod and bearing connection, or as a slider and slide rail connection. The specific form is not limited, as long as the second lifting part 3 can reciprocate in the vertical direction.

[0058] The mounting part 4 is in the form of a telescopic long rod. This is to accommodate the situation where the first lifting part 2 is driven by the drive unit 5 to reciprocate vertically, and the second end of the mounting part 4 and the second lifting part 3 are driven to reciprocate vertically in the opposite direction. In this motion, the mounting part 4 may be compressed or stretched. Therefore, the mounting part 4 is designed to be telescopic. The long rod-shaped mounting part 4 allows the annular crystal part to be easily mounted onto the long rod-shaped mounting part 4 through its hollow structure. The telescopic long rod-shaped mounting part 4 can be a single shaft with elastic elements such as compression springs, springs, and spring sheets, or it can be two shafts that are detachably connected, with elastic elements such as compression springs, spring sheets, and spring sheets connected between the two shafts. The specific form is not limited, as long as the mounting part 4 can extend and retract after mounting the annular crystal part.

[0059] The first end of the mounting part 4 is rotatably connected to the first lifting part 2, and the second end of the mounting part 4 is rotatably connected to the second lifting part 3. The rotatable connection can be a hinge. By setting hinge seats at both ends of the mounting part 4, or by setting hinge seats at the corresponding connection positions of the first lifting part 2 or the second lifting part 3, the mounting part 4 can be rotatably connected to the first lifting part 2 and the second lifting part 3 through a rotating shaft, a latching structure and a hinge seat.

[0060] The mounting part 4 is provided with a first clamping component 41 and a second clamping component 42, and a mounting space 43 is formed between the first clamping component 41 and the second clamping component 42 to clamp and position the annular crystal part. The mounting space 43 is perpendicular to the mounting part 4 so that the upper and lower surfaces of the annular crystal part are placed perpendicular to the mounting part 4, so as to facilitate the stability of the workpiece placement and facilitate the grinding and polishing of the upper and lower edges of the annular crystal part by tilting it, that is, to assist in the grinding and polishing of the double edges of the annular crystal part.

[0061] The first clamping component 41 and the second clamping component 42 can be the same component or components that cooperate with each other to achieve clamping. The first clamping component 41 or the second clamping component 42 can be oppositely arranged claws, two oppositely arranged clamping surfaces, or oppositely arranged thrust ball bearing structures. While forming the mounting space 43, it facilitates the rotation of the annular crystal part during grinding and polishing.

[0062] The drive unit 5 drives the first lifting unit 2 to reciprocate vertically, causing the second end of the mounting unit 4 and the second lifting unit 3 to reciprocate vertically in opposite directions, so that the mounting unit 4 and the first lifting unit 2 form a preset angle. Figure 2 and Figure 3 As shown, the annular crystal part is tilted at a certain angle on this auxiliary device. When it is necessary to polish the edge of any one side of the crystal part, the auxiliary device is placed above the grinding disc 7, so that the mounting space 43 is at least partially in contact with the polishing surface 71 of the grinding disc 7. When it is necessary to polish the edge of the other side, the first lifting part 2 is driven in reverse, which drives the second end of the mounting part 4 and the second lifting part 3, so that the annular crystal part changes the tilt angle on this auxiliary device and is flipped over, thereby realizing the polishing of the double edges of the annular crystal part.

[0063] It should be noted that the first lifting part 2 and the second lifting part 3 of this application can each be configured in multiples, with corresponding mounting parts 4 in multiples, to form multiple mounting spaces 43. This allows the circular crystal double-edge polishing auxiliary device 6 of this application to simultaneously assist multiple circular crystal parts in completing the polishing operation on the grinding disc 7. In another case, considering that the first lifting part 2 is connected to the drive part 5, this application can provide one first lifting part 2 and multiple second lifting parts 3, with the number of mounting parts 4 being the same as that of the second lifting parts 3. This also enables the simultaneous mounting and polishing of multiple circular crystal parts. Furthermore, considering the overall aesthetics and structural rationality of the auxiliary device, the first lifting part 2 can be positioned at the center of the auxiliary device, with the second lifting parts 3 and mounting parts 4 arranged in a circumferential array around the first lifting part 2. The specific form is not limited and can be determined according to the actual situation.

[0064] The present invention provides a grinding and polishing auxiliary device 6 and a grinding and polishing equipment for a circular crystal part with double edges. The grinding and polishing auxiliary device 6 for a circular crystal part with double edges includes a support part 1, a first lifting part 2, a second lifting part 3, a clamping part 4, and a driving part 5. The first lifting part 2 and the second lifting part 3 are both rotatably mounted on the support part 1, and the second lifting part 3 is spaced apart from the first lifting part 2. The clamping part 4 is in the shape of a telescopic long rod. The first end of the clamping part 4 is rotatably connected to the first lifting part 2, and the second end of the clamping part 4 is rotatably connected to the second lifting part 3. The clamping part 4 is provided with a first clamping component 41 and a second clamping component 42, and a clamping space 43 is formed between the first clamping component 41 and the second clamping component 42. The clamping space 43 is perpendicular to the clamping part 4. The driving part 5 is mounted on the support part 1 and connected to the first lifting part 2. The driving part 5 drives the first lifting part 2 to reciprocate in the vertical direction, and drives the second end of the clamping part 4 and the second lifting part 3 to reciprocate vertically in opposite directions, so that the clamping part 4 and the first lifting part 2 are at a preset angle. When it is necessary to polish the double edges of the ring-shaped crystal part, the ring-shaped crystal part is installed perpendicular to the mounting part 4 through the mounting space 43 provided by the mounting part 4. The first clamping component 41 and the second clamping component 42 clamp and position the crystal part. Under the drive of the drive part 5, the two ends of the mounting part 4 are driven by the first lifting part 2 and the second lifting part 3, so that the mounting part 4 and the first lifting part 2 are at a preset angle, so that the ring-shaped crystal part is at a certain tilt angle on this auxiliary device. When it is necessary to polish the edge of any one side of the crystal part, the auxiliary device is placed above the grinding disc 7, so that the mounting space 43 is at least partially in contact with the polishing surface 71 of the grinding disc 7. When it is necessary to polish the edge of the other side, the first lifting part 2 is driven in reverse, which drives the second end of the mounting part 4 and the second lifting part 3, so that the ring-shaped crystal part changes the tilt angle on this auxiliary device and is flipped over, thereby realizing the polishing of the double edges of the ring-shaped crystal part. The circular crystal part double-edge grinding and polishing auxiliary device 6 and grinding and polishing equipment provided by this invention realize the mounting, positioning, flipping, and grinding and polishing operations of the circular crystal part through the cooperation of the structural components, saving labor costs and improving the work efficiency and workpiece placement stability of the grinding and polishing operation compared with the prior art. Through the application of this invention, the problems of existing technologies requiring large labor costs, low efficiency, and inability to guarantee product quality stability in the grinding and polishing of crystal parts with double edges are solved.

[0065] like Figure 4As shown, in some embodiments, the mounting part 4 includes a first shaft 44 and a second shaft 45. A first clamping assembly 41 is provided on the outer side of the first shaft 44, and a second clamping assembly 42 is provided on the outer side of the second shaft 45. The first end of the first shaft 44 is hinged to the first lifting part 2, and the second end of the second shaft 45 is hinged to the second lifting part 3. The first end of the second shaft 45 is provided with an inner cavity 451, and the second end of the first shaft 44 is at least partially engaged with the side wall of the inner cavity 451. The side of the inner cavity 451 away from the first end of the second shaft 45 is the cavity bottom, and an internal compression spring 46 is provided between the second end of the first shaft 44 and the cavity bottom.

[0066] Specifically, to facilitate the placement and positioning of the annular crystal component in the mounting space 43 provided by the mounting part 4 for subsequent grinding and polishing operations, and to facilitate the mounting and dismounting of the annular crystal component in the mounting part 4, the mounting part 4 of the annular crystal component double-edge grinding and polishing auxiliary device 6 of this application includes a first shaft 44 and a second shaft 45. The first end of the first shaft 44 is hinged to the first lifting part 2, and the second end of the second shaft 45 is hinged to the second lifting part 3. The connection between the first end of the first shaft 44 and the first lifting part 2 or the second end of the second shaft 45 and the second lifting part 3 can be a pin hole and pin shaft connection, or it can be a universal connector connection. To achieve the mating connection of the two shafts, the first end of the second shaft 45 is provided with an inner cavity 451, and the second end of the first shaft 44 is at least partially mating with the side wall of the inner cavity 451. This arrangement makes the mounting part 4 easy to separate and disassemble, thereby facilitating the mounting and dismounting of the annular crystal component and improving the convenience provided by the auxiliary device of this application. Correspondingly, in order to provide a mounting space 43 for mounting the annular crystal component, a first clamping assembly 41 is provided on the outer side of the first shaft 44, and a second clamping assembly 42 is provided on the outer side of the second shaft 45.

[0067] To address the issue of compression or stretching of the mounting part 4 during the reciprocating motion of the first lifting part 2 driven by the drive unit 5 in the vertical direction, and the reciprocating motion of the second end of the mounting part 4 and the second lifting part 3 in the opposite direction, this application incorporates a built-in compression spring 46. The side of the inner cavity 451 furthest from the first end of the second shaft 45 is the cavity bottom. A built-in compression spring 46 is positioned between the second end of the first shaft 44 and the cavity bottom. This built-in compression spring 46 allows the mounting part 4 to extend and retract based on the cooperative connection between the first shaft 44 and the second shaft 45, thereby mitigating compression or stretching and improving the flexibility of mounting the annular crystal component.

[0068] like Figure 4As shown, in some embodiments, the first clamping assembly 41 includes a first thrust ball bearing 411 sleeved on the outside of the first shaft 44; the second clamping assembly 42 includes a second thrust ball bearing 421 sleeved on the outside of the second shaft 45; the first thrust ball bearing 411 and the second thrust ball bearing 421 are arranged opposite to each other, and a clamping space 43 is formed between the first thrust ball bearing 411 and the second thrust ball bearing 421.

[0069] Specifically, considering that the annular crystal part will continuously rotate around the mounting part 4 as the axis under the drive of the grinding and polishing surface 71 of the grinding disc 7 during the subsequent grinding and polishing operation, in order to ensure stable and smooth rotation, the first clamping assembly 41 and the second clamping assembly 42 of this application are configured as a first thrust ball bearing 411 sleeved on the outside of the first shaft 44 and a second thrust ball bearing 421 sleeved on the outside of the second shaft 45. While forming the mounting space 43 to clamp and position the annular crystal part, the first thrust ball bearing 411 and the second thrust ball bearing 421, due to their structural characteristics, can assist the rotational movement of the annular crystal part during the grinding and polishing process, thereby making the rotation of the annular crystal part more stable and smooth, and ensuring the product quality stability of the crystal part after double-edge grinding and polishing.

[0070] Furthermore, when the first thrust ball bearing 411 and the second thrust ball bearing 421 clamp and position the upper and lower surfaces of the annular crystal component, a shim can be provided on the side of the first thrust ball bearing 411 near the annular crystal component in order to protect the annular crystal component, and the same applies to the second thrust ball bearing 421.

[0071] like Figure 4 As shown, in some embodiments, the second clamping assembly 42 further includes a locking nut 422 and an external compression spring 423 sleeved on the outside of the second shaft 45; the locking nut 422 and the second thrust ball bearing 421 are spaced apart, and the two ends of the external compression spring 423 are respectively connected to the locking nut 422 and the second thrust ball bearing 421.

[0072] Specifically, considering that the mounting part 4 of this application is a telescopic long rod, the telescopic movement of the first shaft 44 and the second shaft 45 through the built-in compression spring 46 may cause disturbance to the first thrust ball bearing 411 and the second thrust ball bearing 421 sleeved outside the first shaft 44 and the second shaft 45. In order to reduce the disturbance, since the inner cavity 451 where the built-in spring is placed is located inside the second shaft 45, the second clamping assembly 42 of this application also includes a locking nut 422 and an external compression spring 423 sleeved outside the second shaft 45; the locking nut 422 and the second thrust ball bearing 423 sleeved outside the second shaft 45. The ball bearings 421 are spaced apart, and the two ends of the external compression spring 423 are respectively connected to the locking nut 422 and the second thrust ball bearing 421. The external compression spring 423 resists the disturbance of the second thrust ball bearing 421 by the extension and retraction movement of the internal compression spring 46. At the same time, it can buffer the axial micro-runout of the mounting part 4 caused by the edge polishing of the annular crystal part, so that the pre-pressure applied to the annular crystal part during polishing is within a suitable range, ensuring the stability of the mounting part 4, the mounting space 43 and the mounted annular crystal part during the polishing operation and the flipping and turning process.

[0073] In one mounting method of this application, the cotter pin between the second end of the mounting part 4 and the second lifting part 3 is opened, the second shaft 45 is removed, and the locking nut 422, the external compression spring 423, the thrust ball bearing and the washer are removed in one go. Then the annular crystal part can be installed in the mounting space 43. The above-mentioned components are installed in sequence to complete the installation and fixing of the crystal part.

[0074] like Figure 1 As shown, in some embodiments, the support part 1 includes a base 11, a connecting rod 12 and a top cover 13. The base 11 is annular, and the two ends of the connecting rod 12 are respectively connected to the base 11 and the top cover 13. The first lifting part 2 and the second lifting part 3 are spaced apart and can be lifted and lowered on the top cover 13.

[0075] Specifically, as the support frame for the annular crystal double-edge polishing auxiliary device 6 of this application, the support part 1 of this application includes a base 11, a connecting rod 12, and a top cover 13. The base 11 is annular, which provides a certain space on the side of the support part 1 facing the grinding disc 7 for placing the grinding disc 7. This allows the annular crystal double-edge polishing auxiliary device 6 to be installed above the grinding disc 7. While avoiding collisions, this arrangement enhances the tightness between the equipment structures and saves space and reduces costs.

[0076] The two ends of the connecting rod 12 are connected to the base 11 and the top cover 13 respectively. The number and diameter of the connecting rods 12 are not limited, as long as they can ensure the stable support function of the support part 1.

[0077] The first lifting part 2 and the second lifting part 3 are spaced apart and movable on the top cover 13. It should be noted that multiple first lifting parts 2 and multiple second lifting parts 3 can be provided, along with multiple corresponding mounting parts 4, to form multiple mounting spaces 43. This allows the circular crystal double-edge polishing auxiliary device 6 to simultaneously assist multiple circular crystal parts in polishing operations on the grinding disc 7. Alternatively, considering that the first lifting part 2 connects to the drive part 5, this application can provide one first lifting part 2 and multiple second lifting parts 3, with the number of mounting parts 4 matching that of the second lifting parts 3. This also allows for the simultaneous mounting and polishing of multiple circular crystal parts. Furthermore, considering the overall aesthetics and structural rationality of the auxiliary device, the first lifting part 2 can be positioned at the center of the top cover 13, with the second lifting parts 3 and mounting parts 4 arranged circumferentially around the first lifting part 2. The specific form is not limited and can be determined according to the actual situation.

[0078] like Figure 1 and Figure 4 As shown, in some embodiments, the top cover 13 includes an outer ring frame 131 and a connecting inner frame 132, with the connecting inner frame 132 connected to the outer ring frame 131; the first lifting part 2 includes a lifting platform 21 and a lead screw 22; the lead screw 22 is arranged vertically and rotatably connected to the connecting inner frame 132, the lower end of the lead screw 22 is connected to the lifting platform 21, and the upper end of the lead screw 22 is connected to the drive part 5; the lifting platform 21 is hinged to the first end of the mounting part 4, and the drive part 5 drives the lead screw 22 to drive the lifting platform 21 to reciprocate in the vertical direction.

[0079] Specifically, for both aesthetic purposes and cost savings, and to facilitate real-time monitoring of the ring-shaped crystal component's mounting status, flipping, and polishing processes, the top cover 13 of this application can adopt a hollow design. In some embodiments, this application provides a top cover 13 comprising a ring-shaped outer frame 131 and a connecting inner frame 132, with the connecting inner frame 132 connected to the ring-shaped outer frame 131. The ring-shaped outer frame 131 facilitates the connection of the connecting rod 12, the installation of the second lifting part 3, the addition of the external lifting cylinder, and the disassembly and maintenance of the device. The connecting inner frame 132 is a frame structure and can adopt a hollow design or be a spaced-out circumferential partition. In one embodiment of this application, the connecting inner frame 132 is cross-shaped, making the top cover 13 hollow.

[0080] To achieve the lifting and lowering movement of the first lifting part 2, the first lifting part 2 of this application includes a lifting platform 21 and a lead screw 22. The lead screw 22 is arranged vertically and rotatably connected to the connecting inner frame 132. The lower end of the lead screw 22 is connected to the lifting platform 21, and the upper end of the lead screw 22 is connected to the drive unit 5. The lifting platform 21 is hinged to the first end of the mounting part 4, and the drive unit 5 drives the lead screw 22 to drive the lifting platform 21 to reciprocate vertically. Connecting components such as a nut for the lead screw 22 can be added at the connection point; the specific type is not limited. The lifting structure of the lead screw 22 type has the advantages of smooth drive and easy stroke adjustment. It is suitable for adjusting the angle between the mounting part 4 and the first lifting part 2 by adjusting the height of the first lifting part 2, that is, adjusting the angle between the annular crystal part in the mounting space 43 and the polishing surface 71 of the grinding disc 7 during polishing.

[0081] like Figure 1 and Figure 5 As shown, in some embodiments, the outer ring frame 131 has multiple vertical through holes 133; the second lifting part 3 and the mounting part 4 are of the same number, the first end of the multiple mounting parts 4 is connected to the lifting platform 21, the second end of the multiple mounting parts 4 is correspondingly connected to the second lifting part 3, and the multiple second lifting parts 3 are correspondingly embedded in the multiple vertical through holes 133.

[0082] Specifically, in order to enable the circular crystal double-edge polishing auxiliary device 6 of this application to simultaneously assist multiple circular crystal parts in completing the polishing operation on the grinding disc 7, the second lifting part 3 and the mounting part 4 are of equal number. The first end of each mounting part 4 is connected to the lifting platform 21, and the second end of each mounting part 4 is correspondingly connected to the second lifting part 3. In order to realize the liftable connection between the second lifting part 3 and the support part 1, the annular outer frame 131 of the top cover 13 of the support part 1 of this application has multiple vertical through holes 133, and the multiple second lifting parts 3 are correspondingly embedded in the multiple vertical through holes 133. It should be noted that in order to prevent the multiple mounted circular crystal parts from interfering with each other, the circumferential distance of the vertical through holes 133 needs to be controlled. The number of the above-mentioned vertical through holes 133, mounting parts 4 and second lifting parts 3 should be adjusted according to the size of the annular outer frame 131 and the actual polishing needs.

[0083] like Figure 4 As shown, in some embodiments, the second lifting part 3 includes a linear guide rod 31 and a linear bearing 32. The linear bearing 32 is embedded in the vertical through hole 133. The linear guide rod 31 and the linear bearing 32 are connected in cooperation. The lower end of the linear guide rod 31 is hinged to the second end of the mounting part 4.

[0084] Specifically, in order to realize the lifting and lowering movement of the second lifting part 3 and to make the second lifting part 3 cooperate with the vertical through hole 133 opened in the outer ring frame 131, the second lifting part 3 includes a linear guide rod 31 and a linear bearing 32. The linear bearing 32 is embedded in the vertical through hole 133, and the linear guide rod 31 is connected to the linear bearing 32. The lower end of the linear guide rod 31 is hinged to the second end of the mounting part 4. The length of the linear guide rod 31 is determined according to the movement stroke of the first lifting part 2, and also according to the vertical movement distance of the second end of the mounting part 4 required for the mounting part 4 to be flipped and turned.

[0085] like Figure 6 As shown, in some embodiments, the base 11 is provided with a cylinder 111, the output end of the cylinder 111 is connected to the first end of the cylinder push rod 112, and the second end of the cylinder push rod 112 is connected to the top cover 13; the connecting rod 12 is a guide sleeve 121 that can extend and retract in the vertical direction; wherein, the cylinder 111 drives the cylinder push rod 112 to reciprocate in the vertical direction, and the top cover 13 and the guide sleeve 121 reciprocate in the vertical direction.

[0086] Specifically, to enhance the flexibility of the double-edge polishing auxiliary device 6 for the annular crystal parts of this application, and to provide sufficient vertical space for flipping and turning the annular crystal parts, this application provides a cylinder 111 on the base 11. The output end of the cylinder 111 is connected to the first end of the cylinder push rod 112, and the second end of the cylinder push rod 112 is connected to the top cover 13, thereby making the support part 1 liftable. Correspondingly, the connecting rod 12 is a guide sleeve 121 that can extend and retract in the vertical direction, so as to cooperate with the cylinder 111 to complete the overall lifting and lowering of the support part 1. When lifting and lowering are required, the cylinder 111 drives the cylinder push rod 112 to reciprocate in the vertical direction, and the top cover 13 and the guide sleeve 121 reciprocate in the vertical direction. The number of cylinders 111 and cylinder push rods 112 can be determined according to the stability of the structure. They can be rotationally symmetrically arranged in two positions of the base 11, or circumferentially arranged around the base 11. The specific arrangement is not limited, as long as the lifting and lowering of the support can be achieved.

[0087] In one embodiment, when it is necessary to polish the edge of any one side of the crystal part, the auxiliary device is placed above the grinding disc 7 so that the mounting space 43 is at least partially in contact with the polishing surface 71 of the grinding disc 7. When it is necessary to polish the edge of the other side, the cylinder 111 drives the cylinder rod 112 to move the top cover 13 vertically upward, so as to provide vertical space for the flipping of the annular crystal part in advance. By driving the first lifting part 2 in the reverse direction, the second end of the mounting part 4 and the second lifting part 3 are driven to change the tilt angle of the annular crystal part on this auxiliary device and achieve the flipping. Then, the top cover 13 is reset by driving the cylinder 111, thereby realizing the polishing of the double edges of the annular crystal part.

[0088] Example 2

[0089] like Figure 7 As shown, the second aspect of this application provides a polishing device, including a grinding disc 7 and the aforementioned annular crystal double-edge polishing auxiliary device 6; the grinding disc 7 has a polishing surface 71; the annular crystal double-edge polishing auxiliary device 6 is disposed above the grinding disc 7, so that the mounting space 43 is at least partially in contact with the polishing surface 71.

[0090] Specifically, the specific structure of the double-edge polishing auxiliary device 6 for the annular crystal part can be referred to in Embodiment 1, and will not be repeated here.

[0091] The present invention provides a grinding and polishing auxiliary device 6 and a grinding and polishing equipment for a circular crystal part with double edges. The grinding and polishing auxiliary device 6 for a circular crystal part with double edges includes a support part 1, a first lifting part 2, a second lifting part 3, a clamping part 4, and a driving part 5. The first lifting part 2 and the second lifting part 3 are both rotatably mounted on the support part 1, and the second lifting part 3 is spaced apart from the first lifting part 2. The clamping part 4 is in the shape of a telescopic long rod. The first end of the clamping part 4 is rotatably connected to the first lifting part 2, and the second end of the clamping part 4 is rotatably connected to the second lifting part 3. The clamping part 4 is provided with a first clamping component 41 and a second clamping component 42, and a clamping space 43 is formed between the first clamping component 41 and the second clamping component 42. The clamping space 43 is perpendicular to the clamping part 4. The driving part 5 is mounted on the support part 1 and connected to the first lifting part 2. The driving part 5 drives the first lifting part 2 to reciprocate in the vertical direction, and drives the second end of the clamping part 4 and the second lifting part 3 to reciprocate vertically in opposite directions, so that the clamping part 4 and the first lifting part 2 are at a preset angle. When it is necessary to polish the double edges of the ring-shaped crystal part, the ring-shaped crystal part is installed perpendicular to the mounting part 4 through the mounting space 43 provided by the mounting part 4. The first clamping component 41 and the second clamping component 42 clamp and position the crystal part. Under the drive of the drive part 5, the two ends of the mounting part 4 are driven by the first lifting part 2 and the second lifting part 3, so that the mounting part 4 and the first lifting part 2 are at a preset angle, so that the ring-shaped crystal part is at a certain tilt angle on this auxiliary device. When it is necessary to polish the edge of any one side of the crystal part, the auxiliary device is placed above the grinding disc 7, so that the mounting space 43 is at least partially in contact with the polishing surface 71 of the grinding disc 7. When it is necessary to polish the edge of the other side, the first lifting part 2 is driven in reverse, which drives the second end of the mounting part 4 and the second lifting part 3, so that the ring-shaped crystal part changes the tilt angle on this auxiliary device and is flipped over, thereby realizing the polishing of the double edges of the ring-shaped crystal part. The circular crystal part double-edge grinding and polishing auxiliary device 6 and grinding and polishing equipment provided by this invention realize the mounting, positioning, flipping, and grinding and polishing operations of the circular crystal part through the cooperation of the structural components, saving labor costs and improving the work efficiency and workpiece placement stability of the grinding and polishing operation compared with the prior art. Through the application of this invention, the problems of existing technologies requiring large labor costs, low efficiency, and inability to guarantee product quality stability in the grinding and polishing of crystal parts with double edges are solved.
