Description

Technical Field

[0001] This application relates to the technical field of quartz crucible grinding, and specifically relates to a grinding device and method for quartz crucibles. Background Art

[0002] A quartz crucible is a high-temperature-resistant container made of high-purity quartz, which is widely used in experimental and industrial fields such as metallurgy, chemical engineering, semiconductor manufacturing, etc. It can be used at high temperatures up to 1000 degrees or even 1500 degrees for a short time. It has excellent chemical stability, can resist the erosion of most acids and alkalis, has a small thermal expansion coefficient, good thermal shock performance, and is suitable for occasions with rapid temperature changes. At the same time, it also has good light transmittance, which is convenient for observing the internal reaction process. However, when using it, it is necessary to pay attention to avoiding rapid temperature changes and contact with corrosive chemicals such as hydrofluoric acid to ensure safety and the performance of the crucible.

[0003] After the production of the quartz crucible, it is necessary to grind the surface of the quartz crucible. Grinding the surface of the quartz crucible is to improve its overall performance and ensure the smooth progress of the experimental or industrial process. This process can remove the tiny bubbles, cracks and other impurities generated during manufacturing, increase the smoothness of the crucible surface, reduce the adhesion of molten substances, facilitate pouring and cleaning, improve the heat conduction efficiency at the same time, reduce local overheating, enhance chemical corrosion resistance, improve the appearance for easy observation, and reduce the pollution caused by the shedding of tiny particles, so as to ensure the efficient and safe use of the crucible during high-temperature treatment.

[0004] Referring to the Chinese patent document with the publication number CN119304743A and the name of a quartz crucible grinding device, this device adjusts the position of the support shell through an adjustment shell, enabling the device to grind quartz crucibles of different specifications, making the grinding disc contact the quartz crucible, and grinding the inner wall or outer wall of the quartz crucible by adjusting the support shell in the positive and negative positions.

[0005] For the above technical solution, during the process of grinding the outer side wall of the quartz crucible, it is necessary for the staff to move the cooled quartz crucible and place it on the three-jaw chuck, and the three-jaw chuck abuts against the inner side wall of the quartz crucible. After abutting against the inner wall of the quartz crucible, the outer side wall of the quartz crucible is ground. A large amount of manpower is required during the transfer process of the quartz crucible, which affects work efficiency. At the same time, it is easy to cause bumps and damages to the corners of the quartz crucible during manual handling. Summary of the Invention

[0006] In view of this, this application provides a grinding device and method for quartz crucibles, aiming to solve the problem that when grinding the side wall of the quartz crucible, it is necessary for the staff to drive the quartz crucible to move, and it is easy to cause bumps when placing the quartz crucible.

[0007] In a first aspect, a polishing device for a quartz crucible provided by the present application adopts the following technical solution: A polishing device for a quartz crucible provided by the present application adopts the following technical solution, including a polishing frame and a polishing mechanism arranged on the polishing frame; a rotating rod is arranged on the polishing frame, a connecting block is fixedly connected to the rotating rod, a sliding groove is formed in the connecting block, a clamping plate is slidably connected to the connecting block, and the clamping plate is slidably connected in the sliding groove. A sliding block is slidably connected to the clamping plate, and a pressing roller is rotatably connected to the sliding block. The pressing roller is used to abut against the outer side wall of the quartz crucible.

[0008] First, place the quartz crucible on the polishing frame. Then, the operator moves the connecting block fixed on it through the rotating rod. The movement of the connecting block drives the clamping plate to slide in the sliding groove, so as to approach the side wall of the quartz crucible. Subsequently, the sliding block on the clamping plate moves accordingly, and drives the pressing roller rotating on it to approach the outer side wall of the quartz crucible. When the pressing roller contacts the side wall of the quartz crucible, the operator continues to adjust the rotating rod to make the pressing roller tightly abut against the outer side wall of the quartz crucible. At this time, the polishing mechanism starts to work to polish the quartz crucible. During the whole process, the sliding and rotation of the clamping plate and the pressing roller ensure the uniformity and accuracy of polishing, and realize efficient and stable polishing operation.

[0009] The pressing roller can evenly distribute the force on the side wall of the quartz crucible, avoiding excessive local pressure and reducing the risk of crucible damage caused by uneven pressure. The rotation and position adjustment of the pressing roller can be precisely controlled, ensuring the stability of the quartz crucible and the polishing accuracy during the polishing process. The use of the pressing roller reduces the possible damage to the crucible caused by directly holding it by hand or mechanical fixtures, and extends the service life of the crucible.

[0010] Optionally, a pushing rod is fixedly connected to the connecting block. The pushing rod is used to drive the connecting block to rotate. A rotating thread is formed on the pushing rod. A rotating block is rotatably connected to the pushing rod. A threaded block is rotatably connected to the rotating block. The threaded block is in threaded connection with the pushing rod. A pushing bar is rotatably connected to the rotating block. One end of the pushing bar is rotatably connected to the clamping plate.

[0011] By rotating the pushing rod and the threaded block, the positions of the clamping plate and the pressing roller can be precisely controlled to ensure that the quartz crucible moves to the middle position of the connecting block, thereby realizing the precise alignment of the quartz crucible and providing an accurate basis for subsequent polishing or other processing steps.

[0012] Optionally, a pushing connecting rod is fixedly connected to the sliding block. Threads are provided on the pushing connecting rod. An adjusting rotating rod is rotatably connected to the clamping plate. The adjusting rotating rod and the pushing connecting rod are connected by threads. By rotating the adjusting rotating rod, the contact distance between the abutting roller and the quartz crucible can be controlled.

[0013] Optionally, an abutting plate is slidably connected to the sliding block. An abutting cylinder is fixedly connected to the sliding block. The output shaft of the abutting cylinder is fixedly connected to the abutting plate. The abutting plate is used to abut against the lower opening of the quartz crucible.

[0014] Optionally, an adjusting cylinder is fixedly connected to the grinding frame. The output shaft of the adjusting air rod is rotatably connected to the rotating rod.

[0015] Optionally, a three-jaw chuck is rotatably connected to the grinding frame. The three-jaw chuck is used for centering the quartz crucible. An inner support block is rotatably connected to the three-jaw chuck. The outer surface of the inner support block is flexible. The inner support block is used to support the inner wall of the quartz crucible.

[0016] Optionally, a rotating motor is fixedly connected to the grinding frame. The output shaft of the rotating motor and the three-jaw chuck are connected by a belt drive.

[0017] The centering operation ensures the stability of the quartz crucible during the grinding process. By fixing the central position of the crucible, the grinding of the outer wall is made more uniform and precise. This helps to prevent the crucible from shifting or vibrating during the grinding process, thereby improving the grinding quality and efficiency. Centering can also reduce the risk of uneven grinding or over-grinding caused by the offset of the crucible position, and extend the service life of the crucible. In addition, the centering operation makes the grinding process more automated and standardized, reduces the technical requirements for operators, reduces human errors, improves production safety and product consistency.

[0018] Optionally, the grinding mechanism includes a first connecting block fixedly connected to the grinding frame. A second connecting block is slidably connected to the first connecting block. A third connecting block is slidably connected to the second connecting block. A grinding motor is rotatably connected to the third connecting block. A grinding roller is fixedly connected to the output shaft of the grinding motor. A control cylinder is fixedly connected to the third connecting block. An adjusting roller is fixedly connected to the output shaft of the control cylinder. A grinding belt is sleeved on the grinding roller and the adjusting roller.

[0019] In a second aspect, a grinding method for a quartz crucible, the grinding method is as follows: S1. When grinding the quartz crucible, start the adjusting cylinder to move the output shaft of the adjusting cylinder upward. After the connecting block moves upward beyond the height of the quartz crucible, the staff drives the push rod to rotate, causing the connecting block on the push rod to rotate. When the connecting block moves above the quartz crucible, retract the output shaft of the adjusting cylinder to drive the connecting block to move downward. S2. The clamping plates on the connecting block move to both sides of the quartz crucible and drive the threaded block to rotate at this time, causing the rotating block to move toward the side close to the connecting block. When the rotating block moves, it drives the push bar to move, and the push bar drives the clamping plate to slide in the sliding groove, making the abutting roller on the sliding groove abut against the side wall of the quartz crucible. During the continuous movement, the abutting roller moves to the midline position of the quartz crucible. S3. Rotate the adjusting lever to increase the distance between the adjusting lever and the push connecting rod. During this process, the abutting roller on the sliding block abuts against the surface of the quartz crucible. Start the adjusting cylinder to drive the quartz crucible to move upward, and after moving upward, drive the push rod to rotate, and drive the quartz crucible to the three-jaw chuck for grinding.

[0020] The synchronous movement of the abutting rollers can provide a stable clamping force, preventing the quartz crucible from shaking or displacing during movement and ensuring the stability of the processing process. When the abutting rollers move to the midline of the side wall of the quartz crucible, it can ensure that uniform pressure is applied to the crucible during the entire grinding process, avoiding damage caused by local overpressure.

[0021] Optionally, in step S3, after driving the quartz crucible to move upward, start the abutting cylinder to move the output shaft of the abutting cylinder and drive the abutting plate to move toward the opening of the quartz crucible to support the opening of the quartz crucible. When the quartz crucible moves to the three-jaw chuck, use the inner support blocks on the three-jaw chuck to support and center the inner wall of the quartz crucible. Then start the rotating motor to drive the quartz crucible to rotate, and start the grinding motor to drive the grinding belt to rotate to grind the surface of the quartz crucible.

[0022] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects: 1. The abutting rollers can evenly distribute the force on the side wall of the quartz crucible, avoiding excessive local pressure and reducing the risk of crucible damage caused by uneven pressure. The rotation and position adjustment of the abutting rollers can be precisely controlled, ensuring the stability and grinding accuracy of the quartz crucible during the grinding process. The use of abutting rollers reduces the possible damage to the crucible caused by direct hand-holding or mechanical jigs, extending the service life of the crucible.

[0023] 2. By rotating the push rod and the threaded block, the positions of the clamping plate and the abutting roller can be precisely controlled to ensure that the quartz crucible is moved to the middle position of the connecting block, thereby achieving precise alignment of the quartz crucible and providing an accurate basis for subsequent grinding or other processing steps.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below in conjunction with the Figures 1-7 of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by this application.

[0027] In a first aspect, a grinding device for a quartz crucible provided by this application adopts the following technical solutions: As Figure 1As shown in the figure, this embodiment provides a polishing device for a quartz crucible, which includes a polishing frame 1, a polishing mechanism 2, a clamping mechanism, an adjusting mechanism, an abutting mechanism, and a centering mechanism. The polishing frame 1 is placed on a horizontal plane. The polishing mechanism 2 is used to polish the outer wall of the quartz crucible. The clamping mechanism is used to clamp the outer wall of the quartz crucible to facilitate the movement of the quartz crucible. The adjusting mechanism is used to adjust the distance between the clamping mechanism and the quartz crucible. The abutting mechanism is used to abut against the bottom position of the quartz crucible. The centering mechanism is used to center the quartz crucible to facilitate the uniform polishing of the side wall of the quartz crucible.

[0028] As Figure 1 shown in the figure, the polishing mechanism 2 includes a first connecting block 21, a second connecting block 22, a third connecting block 23, a polishing motor 24, a polishing roller 25, a control cylinder 26, an adjusting roller 27, and a polishing belt 28. The first connecting block 21 is fixedly connected to the polishing frame 1. The second connecting block 22 is slidably connected to the first connecting block 21. The third connecting block 23 is slidably connected to the second connecting block 22. The polishing motor 24 is fixedly connected to the third connecting block 23. The polishing roller 25 is fixedly connected to the output shaft of the polishing motor 24. The control cylinder 26 is fixedly connected to the third connecting block 23. The adjusting roller 27 is rotatably connected to the output shaft of the control cylinder 26. The polishing belt 28 is sleeved on the polishing roller 25 and the adjusting roller 27.

[0029] When it is necessary to polish the quartz crucible, by driving the second connecting block 22 to move, the third connecting block 23 moves in the vertical direction. When it moves to a certain extent, drive the third connecting block 23 to move, so that the third connecting block 23 moves parallel to the horizontal plane. By the movement of the first connecting block 21 and the second connecting block 22, the polishing belt 28 is driven to move to the side wall of the quartz crucible. Start the polishing motor 24, so that the polishing motor 24 drives the polishing roller 25 to rotate, and then drives the polishing belt 28 to rotate to polish the side wall of the quartz crucible. When polishing different side walls of the quartz crucible, by driving the output shaft of the control cylinder 26 to extend or retract to drive the adjusting roller 27 to move, to polish different side walls of the quartz crucible.

[0030] As Figure 2 and Figure 3As shown in the figure, the clamping mechanism includes an adjusting cylinder 7, a rotating rod 3, a connecting block 31, a sliding groove 32, a clamping plate 33, a sliding block 34 and a contact roller 35. The adjusting cylinder 7 is fixedly connected to the grinding frame 1. The rotating rod 3 is rotatably connected to the output shaft of the adjusting cylinder 7. The connecting block 31 is fixedly connected to the rotating rod 3. The sliding groove 32 is formed in the connecting block 31. The clamping plate 33 is slidably connected to the connecting block 31 and is arranged in the sliding groove 32. The sliding block 34 is slidably connected to the clamping plate 33. The contact roller 35 is rotatably connected to the sliding block 34. When the sliding block 34 moves, the contact roller 35 can move towards or away from the side wall of the quartz crucible.

[0031] When it is necessary to move the quartz crucible, by starting the adjusting cylinder 7, the output shaft of the adjusting cylinder 7 moves upward, and the rotating rod 3 located above the output shaft moves upward. The staff drives the rotating rod 3 to rotate, so that the connecting block 31 rotates to a position above the quartz crucible. Push the clamping plate 33 to move on the sliding groove 32, so that the clamping plate 33 moves to both sides of the center of the quartz crucible, and push the sliding block 34 to move towards the position close to the quartz crucible, so that the contact roller 35 on the sliding block 34 abuts against the side wall of the quartz crucible.

[0032] As Figure 2 , Figure 3 and Figure 5 As shown in the figure, the adjusting mechanism includes a push rod 4, a rotating thread 41, a rotating block 42, a threaded block 43 and a push bar 44. The push rod 4 is fixedly connected to the connecting block 31. The push rod 4 is used to facilitate the staff to drive the connecting block 31 to rotate. The rotating thread 41 is formed on the push rod 4. The rotating block 42 is rotatably connected to the push rod 4. A threaded block 43 is rotatably connected to the rotating block 42, and the threaded block 43 and the push rod 4 are connected by the rotating thread 41. A push bar 44 is rotatably connected to the rotating block 42. One end of the push bar 44 away from the rotating block 42 is rotatably connected to the clamping plate 33.

[0033] When it is necessary to clamp the quartz crucible, the staff drives the push rod 4 to rotate, and after rotation, rotates the rotating thread 41, so that the threaded block 43 moves towards the side away from the connecting block 31. During this process, the push bar 44 on the rotating block 42 moves towards the side away from the connecting block 31, driving the clamping plate 33 on the push bar 44 to move towards the side away from the connecting block 31, to facilitate the quartz crucible to move to the middle position of the connecting block 31. After moving to the position of the quartz crucible, drive the connecting block 31 to move downward through the adjusting cylinder 7, and through the rotating thread 41, make the threaded block 43 move towards the position close to the connecting block 31, so that the push bar 44 and the clamping plate 33 move towards the position close to the connecting block 31, and make the contact roller 35 move to the middle line of the side wall of the quartz crucible.

[0034] Among them, as Figure 4 , Figure 6 and Figure 7 shown, a pushing connecting rod 5 is fixedly connected to the sliding block 34. A thread is provided on the pushing connecting rod 5. An adjusting rotating rod 51 is rotatably connected to the clamping plate 33. The adjusting rotating rod 51 and the pushing connecting rod 5 are connected by a thread. By rotating the adjusting rotating rod 51, the contact distance between the abutting roller 35 and the quartz crucible can be controlled.

[0035] When the abutting roller 35 moves to the midline of the side wall of the quartz crucible, rotate the adjusting rotating rod 51 to increase the distance between the adjusting rotating rod 51 and the pushing connecting rod 5. During the process of increasing the distance, make the abutting roller 35 abut against the side wall of the quartz crucible. By flipping the adjusting rotating rod 51, the distance between the adjusting rotating rod 51 and the pushing connecting rod 5 can be reduced, and during the process of reducing the distance, the abutting roller 35 can be moved away from the side wall of the quartz crucible.

[0036] As Figure 6 and Figure 7 shown, the abutting mechanism includes an abutting plate 6 and an abutting cylinder 61. The abutting plate 6 is slidably connected to the sliding block 34. The abutting cylinder 61 is fixedly connected to the sliding block 34, and the output shaft of the abutting cylinder 61 is fixedly connected to the abutting plate 6. The abutting plate 6 is used to abut in the opening direction of the quartz crucible.

[0037] When it is necessary to transfer the quartz crucible, the abutting roller 35 abuts against the side wall of the quartz crucible, and the adjusting cylinder 7 is driven to lift the quartz crucible. After the quartz crucible is lifted, start the abutting cylinder 61 to extend the output shaft of the abutting cylinder 61, drive the abutting plate 6 to move towards the opening of the quartz crucible, and make the abutting plate 6 abut from the opening of the quartz crucible after moving.

[0038] As Figure 2 and Figure 3 shown, the centering mechanism includes a three-jaw chuck 8, an inner support block 81 and a rotating motor 82. The three-jaw chuck 8 is rotatably connected to the grinding frame 1. The three-jaw chuck 8 is used to center the quartz crucible. The inner support block 81 is rotatably connected to the three-jaw chuck 8. The surface of the inner support block 81 is flexible. The inner support block 81 is used to support the inner wall of the quartz crucible. The rotating motor 82 is fixedly connected to the grinding frame 1. The rotating motor 82 and the three-jaw chuck 8 are connected by a belt drive.

[0039] By driving the claws on the three-jaw chuck 8 to move, the inner support blocks 81 located on the claws are abutted against the inner side wall of the quartz crucible, and the quartz crucible is centered during the abutting process. When it is necessary to polish the quartz crucible, the rotation motor 82 is started, and the three-jaw chuck 8 is driven to rotate by the rotation motor 82, so that the quartz crucible located on the three-jaw chuck 8 rotates under the drive of the three-jaw chuck 8, thereby polishing the outer side wall of the quartz crucible.

[0040] When in use of the present application, when it is necessary to clamp the quartz crucible, the staff drives the push rod 4 to rotate, and after rotation, the thread 41 is rotated, so that the thread block 43 moves toward the side away from the connection block 31, and during this process, the push bar 44 located on the rotating block 42 moves toward the side away from the connection block 31, driving the clamping plate 33 located on the push bar 44 to move toward the side away from the connection block 31, to facilitate the movement of the quartz crucible to the middle position of the connection block 31. After moving to the position of the quartz crucible, the connection block 31 is driven to move downward by the adjusting cylinder 7, and by rotating the thread 41, the thread block 43 moves toward the position close to the connection block 31, so that the push bar 44 and the clamping plate 33 move toward the position close to the connection block 31, and the abutting roller 35 moves to the middle line of the side wall of the quartz crucible.

[0041] When the abutting roller 35 moves to the middle line of the side wall of the quartz crucible, the adjusting rotating rod 51 is rotated, so that the distance between the adjusting rotating rod 51 and the push connecting rod 5 increases. During the process of the distance increasing, the abutting roller 35 abuts against the side wall of the quartz crucible. By flipping the adjusting rotating rod 51, the distance between the adjusting rotating rod 51 and the push connecting rod 5 can be reduced, and during the process of the distance reducing, the abutting roller 35 can be moved away from the side wall of the quartz crucible.

[0042] When it is necessary to transfer the quartz crucible, the abutting roller 35 abuts against the side wall of the quartz crucible, and the quartz crucible is driven to move upward by the adjusting cylinder 7. After the quartz crucible moves upward, the abutting cylinder 61 is started, so that the output shaft of the abutting cylinder 61 extends forward, driving the abutting plate 6 to move toward the opening of the quartz crucible, and after moving, the abutting plate 6 abuts against the opening of the quartz crucible.

[0043] By driving the push rod 4 to move, the push rod 4 drives the quartz crucible to move to the upper position of the three-jaw chuck 8, and under the drive of the adjusting cylinder 7, it moves downward, so that the lower position of the abutting plate 6 abuts against the three-jaw chuck 8, and the output shaft of the push cylinder is retracted, driving the abutting plate 6 to move. After moving, by driving the quartz crucible to continue to move, the opening of the quartz crucible is moved to the three-jaw chuck 8.

[0044] By driving the claws on the three-jaw chuck 8 to move, the inner support blocks 81 on the claws are abutted against the inner sidewall of the quartz crucible, and the quartz crucible is centered during the abutting process. When the quartz crucible needs to be polished, the rotation motor 82 is started, and the three-jaw chuck 8 is driven to rotate by the rotation motor 82, so that the quartz crucible on the three-jaw chuck 8 rotates driven by the three-jaw chuck 8.

[0045] When the quartz crucible needs to be polished, by driving the second connecting block 22 to move, the third connecting block 23 moves in the vertical direction. When the movement reaches a certain extent, the third connecting block 23 is driven to move, so that the third connecting block 23 moves parallel to the horizontal plane. (The movement here can use a drag chain to drive the second connecting block 22 or the third connecting block 23 to move, which will not be elaborated here.) The grinding belt 28 is driven to move to the sidewall of the quartz crucible by the movement of the first connecting block 21 and the second connecting block 22. The grinding motor 24 is started, and the grinding motor 24 drives the grinding roller 25 to rotate, thereby driving the grinding belt 28 to rotate to polish the sidewall of the quartz crucible. When polishing different sidewalls of the quartz crucible, the output shaft of the control cylinder 26 is driven to extend or retract to drive the adjusting roller 27 to move, so as to polish different sidewalls of the quartz crucible.

[0046] In this embodiment, the abutting roller 35 effectively reduces the labor intensity of workers and improves the working conditions. It not only improves the job satisfaction of employees but also reduces the health problems that may be caused by long-term heavy physical labor. At the same time, mechanized polishing reduces the direct contact between workers and the quartz crucible, reduces the operation risk, and improves the safety of the workplace. The maintenance of mechanical equipment is also relatively simple, which helps to quickly respond to problems in production and ensures the continuity and stability of production.

[0047] In this embodiment, by abutting against the opening of the quartz crucible, we achieve the stability and safety of the transfer process. This operation not only provides a stable support point to prevent the crucible from tilting or shaking during transfer but also protects the edge of the crucible opening from damage, maintaining its structural integrity and service performance. At the same time, the precise control of the cylinder makes the movement and positioning of the abutting plate 6 simple, significantly improving the transfer efficiency and reducing the difficulty and error of manual operation. In addition, this abutting method helps to keep the inside of the crucible clean, prevent foreign impurities from entering, and is applicable to quartz crucibles of different sizes and shapes, showing good adaptability.

[0048] In the second aspect, a polishing method for a quartz crucible, the polishing method is as follows: S1. When grinding the quartz crucible, start the adjusting cylinder 7 to move the output shaft of the adjusting cylinder 7 upward. After the connecting block 31 moves upward beyond the height of the quartz crucible, the staff drives the push rod 4 to rotate, so that the connecting block 31 on the push rod 4 rotates. When the connecting block 31 moves above the quartz crucible, retract the output shaft of the adjusting cylinder 7 to drive the connecting block 31 to move downward; S2. The clamping plates 33 on the connecting block 31 move to both sides of the quartz crucible, and at this time drive the threaded block 43 to rotate, so that the rotating block 42 moves toward the side close to the connecting block 31. When the rotating block 42 moves, it drives the push bar 44 to move, and the push bar 44 drives the clamping plate 33 to slide in the sliding groove 32, so that the abutting roller 35 on the sliding groove 32 abuts against the side wall of the quartz crucible, and in the process of continuous movement, the abutting roller 35 moves to the midline position of the quartz crucible; S3. Rotate the adjusting lever 51 to increase the distance between the adjusting lever 51 and the push connecting rod 5. During this process, the abutting roller 35 on the sliding block 34 abuts against the surface of the quartz crucible. Start the adjusting cylinder 7 to drive the quartz crucible to move upward, and after moving upward, drive the push rod 4 to rotate, and drive the quartz crucible to the three-jaw chuck 8 for grinding.

[0049] Optionally, in step S3, after driving the quartz crucible to move upward, start the abutting cylinder 61 to move the output shaft of the abutting cylinder 61 and drive the abutting plate 6 to move toward the opening of the quartz crucible to support the opening of the quartz crucible. When the quartz crucible moves to the three-jaw chuck 8, use the inner support block 81 on the three-jaw chuck 8 to support and center the inner wall of the quartz crucible, and then start the rotating motor 82 to drive the quartz crucible to rotate, and start the grinding motor 24 to drive the grinding belt 28 to rotate to grind the surface of the quartz crucible.

[0050] The implementation principle of a polishing device for a quartz crucible in an embodiment of the present application is as follows: When it is necessary to clamp the quartz crucible, the staff drives the push rod 4 to rotate, and after rotation, rotates the thread 41, so that the thread block 43 moves toward the side away from the connection block 31, and during this process, the push bar 44 on the rotating block 42 moves toward the side away from the connection block 31, driving the clamping plate 33 on the push bar 44 to move toward the side away from the connection block 31, to facilitate the movement of the quartz crucible to the middle position of the connection block 31. When it moves to the position of the quartz crucible, the connection block 31 is driven to move downward by adjusting the cylinder 7, and by rotating the thread 41, the thread block 43 moves toward the position close to the connection block 31, so that the push bar 44 and the clamping plate 33 move toward the position close to the connection block 31, and the abutting roller 35 moves to the middle line of the side wall of the quartz crucible.

[0051] When the abutting roller 35 moves to the middle line of the side wall of the quartz crucible, rotate the adjusting rotating rod 51 to increase the distance between the adjusting rotating rod 51 and the push connecting rod 5. During the process of increasing the distance, the abutting roller 35 abuts against the side wall of the quartz crucible. By flipping the adjusting rotating rod 51, the distance between the adjusting rotating rod 51 and the push connecting rod 5 can be reduced, and during the process of reducing the distance, the abutting roller 35 can be moved away from the side wall of the quartz crucible.

[0052] When it is necessary to transfer the quartz crucible, the abutting roller 35 abuts against the side wall of the quartz crucible, and the quartz crucible is driven to move upward by adjusting the cylinder 7. After the quartz crucible moves upward, start the abutting cylinder 61 to make the output shaft of the abutting cylinder 61 extend forward, driving the abutting plate 6 to move toward the opening of the quartz crucible, and after moving, the abutting plate 6 abuts against the opening of the quartz crucible.

[0053] By driving the push rod 4 to move, the push rod 4 drives the quartz crucible to move to the upper position of the three-jaw chuck 8, and under the drive of the adjusting cylinder 7, it moves downward, so that the lower position of the abutting plate 6 abuts against the three-jaw chuck 8, and the output shaft of the push cylinder is retracted to drive the abutting plate 6 to move. After moving, by driving the quartz crucible to continue moving, the opening of the quartz crucible is moved to the three-jaw chuck 8.

[0054] By driving the claws on the three-jaw chuck 8 to move, the inner support blocks 81 on the claws abut against the inner side wall of the quartz crucible, and the quartz crucible is centered during the abutting process. When it is necessary to polish the quartz crucible, start the rotating motor 82, and the rotating motor 82 drives the three-jaw chuck 8 to rotate, so that the quartz crucible on the three-jaw chuck 8 rotates under the drive of the three-jaw chuck 8.

[0055] When it is necessary to polish the quartz crucible, the second connecting block 22 is driven to move, so that the third connecting block 23 moves vertically. After moving to a certain extent, the third connecting block 23 is driven to move, so that the third connecting block 23 moves parallel to the horizontal plane. The polishing belt 28 is driven by the movement of the first connecting block 21 and the second connecting block 22 to move to the side wall of the quartz crucible. The polishing motor 24 is started, so that the polishing motor 24 drives the polishing roller 25 to rotate, and then drives the polishing belt 28 to rotate to polish the side wall of the quartz crucible. When polishing different side walls of the quartz crucible, the output shaft of the control cylinder 26 is driven to extend or retract to drive the adjusting roller 27 to move, so as to polish different side walls of the quartz crucible.

[0056] The above is the preferred embodiment of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
