Description

Technical Field

[0001] This invention relates to the field of ring polishing technology, and more specifically to a spherical ring polishing machine. Background Technology

[0002] A ring polisher is a specialized piece of equipment used for high-precision polishing of planar optical components. Based on the design of continuous ring polishing, it performs continuous polishing under constant component conditions, thereby achieving extremely high planar accuracy. Ring polishers can process a variety of materials and have a wide range of applications.

[0003] For example, Chinese invention patent CN115008318B discloses a pneumatic loading double-sided ring polisher. By modifying the workpiece loading component, the upper and lower plates can rotate separately without the need for an additional motor drive, enabling simultaneous grinding of both the upper and lower surfaces of the workpiece. The modification effect is significant and the modification cost is low. At the same time, changing the existing weight loading to pneumatic loading can improve the loading accuracy of the ring polisher.

[0004] However, considering the aforementioned patents and existing technologies, current ring polishing machines still have the following shortcomings: Existing ring polishing machines are all planar ring polishing machines, mainly used for polishing planar components. However, with the advancement of technology, many spherical components or parts also have the need for high-precision polishing, which makes it necessary to improve the efficiency and accuracy of spherical polishing. At the same time, due to the irregularity of the outer wall of the sphere, existing spherical polishing equipment makes it difficult to accurately adjust the pressure during the polishing process, which reduces the polishing effect. Summary of the Invention

[0005] The purpose of this invention is to address the problems mentioned above, such as the lack of spherical ring polishing machines, which leads to the need to improve the efficiency and precision of spherical polishing, and the difficulty of accurately adjusting the pressure during the polishing process in existing spherical polishing equipment, thus reducing the polishing effect. This invention provides a spherical ring polishing machine.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: A spherical ring polishing machine includes a sphere, an installation platform, and a rotating cylinder. The rotating cylinder is located at the center of the top of the installation platform, and its bottom is recessed to the inner side of the top of the installation platform, where it is rotatably connected to the installation platform. The installation cylinder is installed at the center of the top of the installation platform and at the center of the inner side of the rotating cylinder, and moves up and down. The limiting and polishing components are evenly arranged around the periphery of the installation cylinder to achieve the limiting placement and polishing of the sphere.

[0007] The limiting grinding assembly includes a cylindrical tube, which is uniformly and fixedly welded to the periphery of the mounting cylinder. A limiting sleeve is fixedly installed on one side of the cylindrical tube by threads, and the opening of the limiting sleeve on the side away from the cylindrical tube contracts inward to limit the sphere. A grinding ring is installed inside the cylindrical tube. After the sphere is placed in the limiting position, the sphere is located between the inner wall of the grinding ring and the limiting sleeve. The opening of the grinding ring wraps around one side of the outer wall of the sphere, and the outer wall of the sphere passes through the opening of the limiting sleeve on the side away from the cylindrical tube and is pressed and contacted with the inner wall of the rotating cylinder's rubber material. The sphere is rotated by the rotation friction of the rotating cylinder.

[0008] The pressure regulating component is located in the center of the inner side of the mounting cylinder, and is used to regulate the pressure of the grinding ring in contact with the ball.

[0009] Furthermore, the bottom of the rotating drum extends outward and sinks to the inner side of the top of the mounting platform, and a bearing ring is placed between the bottom end of the rotating drum and the mounting platform to limit its movement.

[0010] Furthermore, a drive wheel is rotatably connected to the top of the installation platform. The drive wheel is located at the bottom edge of the rotating drum and achieves a transmission connection with the rotating drum through a pressing contact with the bottom edge of the rotating drum. A motor is fixedly installed at the bottom of the installation platform, and the motor is transmissionally connected to the drive wheel.

[0011] Furthermore, a limiting cover plate is fixedly installed at the top of the installation platform. The limiting cover plate is located at the bottom edge of the rotating drum and above the drive wheel, and is used to limit the rotation of the drum and protect the drive wheel.

[0012] Furthermore, an upper sealing plate and a lower sealing plate are fixedly installed at the top and bottom of the mounting cylinder, respectively. A hydraulic cylinder is fixedly installed at the center of the bottom of the mounting platform. The telescopic end of the hydraulic cylinder extends upward through the mounting platform and is fixedly installed at the center of the bottom of the lower sealing plate. Limiting posts are symmetrically fixedly installed on both sides of the bottom of the lower sealing plate. The limiting posts extend downward through the mounting platform and are slidably connected to the mounting platform.

[0013] Furthermore, the limiting grinding assembly also includes a telescopic column, which is slidably connected to the inside of one end of the cylindrical tube via a prism structure. The connecting tube is fitted around the periphery of the telescopic column on the side inside the cylindrical tube, and the periphery of the connecting tube away from the telescopic column is threaded. The grinding ring is fixedly installed to the connecting tube via the thread. The spring is fixedly connected between the end of the telescopic column inside the connecting tube and the inner wall of the connecting tube. The nozzle is fixedly installed at the center of the end of the connecting tube away from the telescopic column. The delivery pipe is connected to the nozzle and is designed as a flexible hose. It is bent inside the telescopic column and passes upward from the middle of the telescopic column through the telescopic column, the cylindrical tube, and the upper sealing plate to deliver the grinding agent.

[0014] Furthermore, the pressure regulating assembly includes a threaded column, which is rotatably connected to the center between the upper and lower sealing plates via a bearing, and the threaded column extends upward through the upper sealing plate. A connecting ring is threadedly engaged with the outer periphery of the threaded column located above the upper sealing plate. A transmission rod is driven between the outer periphery of the connecting ring and one end of the telescopic column. One end of the transmission rod is hinged to the outer periphery of the connecting ring, and the other end is hinged to one end of the telescopic column. A turntable is fixedly installed on the top of the threaded column. A through slot is provided on the upper sealing plate, allowing the transmission rod to move and the delivery pipe to extend upward.

[0015] Furthermore, after the grinding ring is installed with the connecting cylinder, a drainage groove is provided at the bottom of the grinding ring, and a wire groove is intermittently provided on the outer periphery of the middle part of the limiting sleeve.

[0016] Furthermore, an annular groove is provided at the top of the installation platform where it is aligned with the limiting sleeve, and a drain pipe is fixedly installed at the bottom of the installation platform, the drain pipe being connected to the bottom end of one side of the annular groove.

[0017] Furthermore, the outer periphery of the inward contraction area on the side of the limiting sleeve away from the cylindrical tube is uniformly and rollingly connected with balls, the balls being in contact with the outer wall of the sphere, and a limiting cover is fixedly installed on the outer side of the limiting sleeve away from the cylindrical tube, the limiting cover being used to limit the balls.

[0018] The beneficial effects of this invention are as follows:

[0019] This invention, through the cooperative design of a rotating cylinder and a mounting cylinder, allows the ball to be positioned between the limiting sleeve and the grinding ring at the limiting grinding component around the mounting cylinder. By driving the rotation of the rotating cylinder and the reciprocating up-and-down movement of the mounting cylinder, the ball can roll relative to the grinding ring, thereby completing continuous circumferential polishing of the spherical surface. This improves the efficiency and precision of spherical polishing. At the same time, the design of the pressure adjustment component allows for simultaneous adjustment of the pressure between the grinding ring and the outer wall of the ball during the polishing process. This makes the operation convenient, easy to control, and improves the polishing effect. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] A preferred embodiment of the present invention, a spherical ring polishing machine, will be described in detail below:

[0041] Example 1

[0042] like Figures 1-9 , Figures 12-16As shown, a spherical ring polishing machine includes a sphere 1, an installation platform 2, and a rotating cylinder 3. The rotating cylinder 3 is located at the center of the top of the installation platform 2, and the bottom of the rotating cylinder 3 is sunk to the inner side of the top of the installation platform 2 and is rotatably connected to the installation platform 2. The installation cylinder 4 is installed at the center of the top of the installation platform 2 and is located at the center of the inner side of the rotating cylinder 3, and moves up and down. The limiting and polishing components 5 are evenly arranged on the periphery of the installation cylinder 4 to realize the limiting placement and polishing of the sphere 1.

[0043] The limiting grinding assembly 5 includes a cylindrical tube 501, which is uniformly and fixedly welded to the periphery of the mounting tube 4. A limiting sleeve 502 is fixedly installed on one side of the cylindrical tube 501 by threads, and the opening of the limiting sleeve 502 away from the cylindrical tube 501 contracts inward to limit the ball 1. A grinding ring 503 is installed inside the cylindrical tube 501. After the ball 1 is placed in the limiting position, the ball 1 is located between the inner wall of the grinding ring 503 and the limiting sleeve 502. The opening of the grinding ring 503 wraps around one side of the outer wall of the ball 1, and the outer wall of the ball 1 passes through the opening of the limiting sleeve 502 away from the cylindrical tube 501 and is pressed and contacted with the inner wall of the rotating cylinder 3 made of rubber. The rotating cylinder 3 rotates and friction drives the ball 1 to rotate. Therefore, when the rotating drum 3 rotates and the mounting cylinder 4 drives the limiting grinding component 5 to move up and down, the friction between the ball 1 and the inner wall of the rotating drum 3 enables the ball 1 to roll relative to the grinding ring 503, thereby allowing the grinding ring 503 to grind and polish the outer surface of the ball 1.

[0044] The pressure regulating component 6 is located in the center of the inner side of the mounting cylinder 4. The pressure regulating component 6 is used to regulate the pressure between the grinding ring 503 and the ball 1. During the grinding and polishing process of the grinding ring 503 on the outer surface of the ball 1, the pressure regulating component 6 is used to adjust the pressure between the grinding ring 503 and the ball 1 to achieve a better polishing effect.

[0045] like Figures 5-6 As shown, the bottom of the rotating cylinder 3 extends outward and sinks to the inner side of the top of the mounting platform 2, and a bearing ring 7 is placed between the bottom end of the rotating cylinder 3 and the mounting platform 2 to limit the friction between them. The bearing ring 7 reduces the friction between the rotating cylinder 3 and the mounting platform 2, which is beneficial for the rotation of the rotating cylinder 3 on the top of the mounting platform 2.

[0046] like Figures 4-7As shown, a drive wheel 8 is rotatably connected to the top of the mounting platform 2. The drive wheel 8 is located at the bottom edge of the rotating drum 3 and achieves a transmission connection with the rotating drum 3 through a pressing contact with the bottom edge of the rotating drum 3. A motor 9 is fixedly installed at the bottom end of the mounting platform 2, and the motor 9 is transmissionally connected to the drive wheel 8. Therefore, by starting the motor 9, the drive wheel 8 is driven to rotate, and during the rotation of the drive wheel 8, the rotating drum 3 is driven to rotate by the transmission connection between the drive wheel 8 and the bottom edge of the rotating drum 3.

[0047] like Figures 1-2 As shown, a limiting cover plate 10 is fixedly installed on the top of the mounting platform 2. The limiting cover plate 10 is located at the bottom edge of the rotating drum 3 and above the drive wheel 8, and is used to limit the rotating drum 3 and protect the drive wheel 8.

[0048] like Figures 7-10 As shown, an upper sealing plate 401 and a lower sealing plate 402 are fixedly installed at the top and bottom of the mounting cylinder 4, respectively. A hydraulic cylinder 11 is fixedly installed at the center of the bottom of the mounting platform 2. The telescopic end of the hydraulic cylinder 11 extends upward through the mounting platform 2 and is fixedly installed at the center of the bottom of the lower sealing plate 402. Limiting posts 12 are symmetrically fixed on both sides of the bottom of the lower sealing plate 402. The limiting posts 12 extend downward through the mounting platform 2 and are slidably connected to the mounting platform 2. Therefore, the mounting cylinder 4 can be moved up and down by the hydraulic cylinder 11.

[0049] like Figures 15-16 , Figure 18 As shown, a ball bearing 5022 is evenly and rollingly connected to the outer periphery of the inwardly contracting area on the side of the limiting sleeve 502 away from the cylindrical tube 501. The ball bearing 5022 contacts the outer wall of the sphere 1. A limiting cover 5023 is fixedly installed on the outer side of the limiting sleeve 502 away from the cylindrical tube 501, and the limiting cover 5023 is used to limit the ball bearing 5022. The design of the ball bearing 5022 reduces the friction between the sphere 1 and the inner wall of the limiting sleeve 502, allowing the sphere 1 to roll better inside the limiting sleeve 502. The design of the limiting cover 5023 facilitates the assembly of the ball bearing 5022.

[0050] Working principle: When polishing the ball 1, the mounting cylinder 4 is first pushed upward to above the top end face of the rotating cylinder 3 by the action of the hydraulic cylinder 11. Then, the limiting sleeve 502 is threadedly connected to the cylindrical cylinder 501. The limiting sleeve 502 is first removed from the cylindrical cylinder 501. After the ball 1 is placed in, the limiting sleeve 502 is then fixedly connected to the cylindrical cylinder 501 by the thread, so that the ball 1 is located between the inner wall of the limiting sleeve 502 and the polishing ring 503.

[0051] After the ball 1 is placed, the hydraulic cylinder 11 pulls the mounting cylinder 4 back down to the inside of the rotating cylinder 3. At this time, the outer wall of the ball 1, which protrudes outward at the limiting sleeve 502, presses against the inner wall of the rotating cylinder 3 made of rubber. Then, the motor 9 is started, causing the drive wheel 8 to rotate, which in turn causes the rotating cylinder 3 to rotate. At the same time, the hydraulic cylinder 11 drives the mounting cylinder 4 to move up and down reciprocally. Therefore, the up-and-down reciprocating movement of the ball 1 relative to the rotating cylinder 3 driven by the mounting cylinder 4, and the rotation of the rotating cylinder 3 relative to the ball 1, combined with the friction between the ball 1 and the inner wall of the rotating cylinder 3, enable the rotating cylinder 3 to roll inside the limiting sleeve 502, thereby allowing the grinding ring 503 to grind and polish the surface of the ball 1.

[0052] Example 2

[0053] Furthermore, such as Figures 11-17 As shown, the limiting grinding assembly 5 also includes a telescopic column 504. The telescopic column 504 is slidably connected to the inner end of the cylindrical tube 501 via a prism structure, so that the telescopic column 504 can only move telescopically relative to the cylindrical tube 501 and will not rotate. The connecting tube 505 is limitedly sleeved on the outer periphery of the telescopic column 504 located inside the cylindrical tube 501, and the outer periphery of the connecting tube 505 away from the telescopic column 504 is threaded. The grinding ring 503 is fixedly installed to the connecting tube 505 via the thread, which facilitates the disassembly, assembly, and replacement of the grinding ring 503. The spring 506 is fixedly connected between the inner end of the telescopic column 504 located inside the connecting tube 505 and the inner wall of the connecting tube 505. Through the design of the spring 506, when the telescopic column 504 is fixed in position, the connecting tube 505 drives the grinding ring 503 to elastically compress and contact the outer wall of the ball 1, thereby ensuring the stable progress of grinding and polishing (it should be noted that, as Figure 13 , Figure 17 As shown, the connecting cylinder 505 and the telescopic column 504 adopt an assembly design on the sleeve side, which facilitates the installation of the spring 506.

[0054] The nozzle 507 is fixedly installed at the center of the connecting cylinder 505 at the end away from the telescopic column 504. The delivery pipe 508 is connected to the nozzle 507 and adopts a flexible hose design. It is bent inside the telescopic column 504 and passes upward from the middle of the telescopic column 504, through the cylindrical tube 501 and the upper sealing plate 401, for delivering polishing compound. Therefore, the polishing compound can be sprayed onto the surface of the sphere 1 through the nozzle 507, and polished in conjunction with the polishing ring 503. The flexible hose design of the delivery pipe 508 ensures stable delivery of polishing compound during the relative movement of the connecting cylinder 505 and the telescopic column 504.

[0055] like Figures 12-14As shown, after the polishing ring 503 is installed with the connecting cylinder 505, a drainage groove 5031 is provided at the bottom of the polishing ring 503, and a wire groove 5021 is intermittently provided on the outer periphery of the middle part of the limiting sleeve 502. This allows the sprayed polishing compound to flow downward through the drainage groove 5031 and the wire groove 5021.

[0056] like Figures 5-7 As shown, an annular groove 201 is formed at the top of the mounting platform 2, aligned with the limiting sleeve 502. A drain pipe 13 is fixedly installed at the bottom of the mounting platform 2, and the drain pipe 13 is connected to the bottom of one side of the annular groove 201. The polishing compound flowing down from the groove 5021 will fall into the interior of the annular groove 201 and be collected and treated through the drain pipe 13.

[0057] Therefore, during the polishing process, the polishing ring 503 is in elastic compression contact with the outer wall of the ball 1 to keep the polishing ring 503 in contact with the outer wall of the ball 1, thereby ensuring the stable progress of polishing. At the same time, polishing compound can be sprayed onto the surface of the ball 1 through the delivery pipe 508 and the nozzle 507 to cooperate with polishing. The used polishing compound can flow downward and be collected and treated through the drain pipe 13.

[0058] Example 3

[0059] Furthermore, such as Figures 10-11 As shown, the pressure regulating assembly 6 includes a threaded post 601, which is rotatably connected to the center between the upper sealing plate 401 and the lower sealing plate 402 via a bearing. The threaded post 601 extends upward through the upper sealing plate 401. A connecting ring 602 is threadedly engaged with the outer periphery of the threaded post 601 located above the upper sealing plate 401. A transmission rod 603 is connected to the outer periphery of the connecting ring 602 and one end of the telescopic post 504. One end of the transmission rod 603 is hinged to the outer periphery of the connecting ring 602, and the other end is hinged to one end of the telescopic post 504. A turntable 604 is fixedly installed on the top of the threaded post 601. The upper sealing plate 401 has a through groove extending vertically, allowing the transmission rod 603 to move and the delivery pipe 508 to extend upward.

[0060] When pressure adjustment is required during the polishing process, the turntable 604 drives the threaded post 601 to rotate. During the rotation of the threaded post 601, the threaded engagement between the connecting ring 602 and the threaded post 601 causes the connecting ring 602 to move up and down. As the connecting ring 602 moves up and down, the transmission rod 603 between the outer periphery of the connecting ring 602 and one inner end of the telescopic post 504 causes the telescopic post 504 to move synchronously, thus adjusting its position. When the position of the telescopic post 504 changes, the compression state of the spring 506 between the telescopic post 504 and the connecting cylinder 505 changes, thereby altering the pressure exerted between the grinding ring 503 and the outer wall of the ball 1 by the connecting cylinder 505, thus adjusting the pressure during the polishing process.

[0061] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
