Description

Technical Field

[0001] The invention relates to the technical field of optical manufacturing, and in particular to a single-axis polishing mechanism. Background Art

[0002] With the development of modern optical technology, the demand for high-precision optical components is becoming more and more urgent, and the requirements for processing equipment and processing technology of optical components are also getting higher and higher. Computer Controlled Optical Surfacing (CCOS) is an optical processing technology developed in the 1970s. Compared with traditional processing technology, it greatly reduces the dependence on operator experience. At present, small tool CNC polishing technology based on asphalt or polyurethane polishing discs is the most widely used CCOS technology in practical applications. In order to achieve different removal effects and achieve different process purposes, the polishing disc has three different movement modes, double rotation mode, flat rotation mode and self-rotation mode. Among the above three movement modes, the removal effect of the double rotation mode and the flat rotation mode is similar, and both can obtain a near-Gaussian removal function, have strong shaping ability, and are used for local surface shape error correction. Although the self-rotation mode cannot obtain a near-Gaussian removal function that is beneficial to surface shape modification, this method can achieve uniform polishing and has a good edge effect suppression effect. It is generally used for comprehensive medium and high frequency error smoothing. At present, a double-rotation polishing tool is generally used to achieve the above movement. The tool has a complex structure, low structural stability, and unstable tool movement, which causes the problem that the shape of the removal function is distorted, such as non-rotationally symmetrical distribution. Summary of the invention

[0003] The purpose of the embodiment of the present invention is to provide a single-axis polishing mechanism with a simple structure, stable operation and the ability to achieve the same removal effect as conventional double-rotation polishing tools.

[0004] The embodiment of the present invention is achieved as follows:

[0005] Based on the above purpose, an embodiment of the present invention provides a single-axis polishing mechanism, including a tool handle and a grinding and polishing assembly, wherein the grinding and polishing assembly is slidably connected to the tool handle, and the grinding and polishing assembly can slide relative to the tool handle along the axis of the tool handle.

[0006] The single-axis polishing mechanism provided by the present invention has a simple structure. The polishing tool can be installed on the grinding and polishing assembly, and then the grinding and polishing assembly drives the polishing tool to move relative to the tool handle. At this time, the polishing tool can be close to or away from the tool handle, so that a near-Gaussian removal function that is beneficial to surface shape correction and a removal function that is beneficial to smoothing can be easily obtained, so that its removal effect is consistent with that of the previous double-rotation grinding and polishing tool, and the grinding and polishing assembly can ensure the stability of the polishing tool during operation.

[0007] In one implementation of the present embodiment: a slide groove and a through hole are provided on the tool handle, the slide groove extends along the axis of the tool handle, the grinding and polishing assembly is installed in the slide groove, and the end of the grinding and polishing assembly and the slide groove form a chamber, and the through hole is connected to the chamber; the single-axis polishing mechanism also includes a controller, the controller is connected to the chamber through the through hole, and the controller is used to control the size of the chamber.

[0008] The controller can inflate the chamber or extract the gas in the chamber. When the controller inflates the chamber, the pressure in the chamber increases, pushing the grinding and polishing assembly outward. At this time, the distance between the polishing tool and the tool handle increases. When the controller extracts the gas in the chamber, the pressure in the chamber decreases, sucking the grinding and polishing assembly inward. At this time, the distance between the polishing tool and the tool handle decreases.

[0009] In one implementation of the present embodiment: the polishing assembly includes a sliding block and an ejector pin, the sliding block is installed in the sliding groove, the sliding block is slidably connected to the tool handle, the ejector pin is installed at one end of the sliding block away from the tool handle, and the ejector pin is detachably connected to the tool handle.

[0010] When using, different polishing tools may need to be installed with different ejectors due to different structures, and the installation of the sliding block and the tool handle is more complicated and delicate, so it is more convenient to only replace the ejector pin, and it will not affect the accuracy of polishing.

[0011] In one implementation of the present embodiment: a positioning groove is provided on the sliding block, the extension direction of the positioning groove is parallel to the axis direction of the sliding block, and the positioning groove is spaced apart from the end of the sliding block near the tool handle; a positioning hole is provided on the tool handle, and a positioning pin is installed on the tool handle, the positioning pin is clamped in the positioning groove after passing through the positioning hole, and the positioning pin can slide in the positioning groove relative to the sliding block along the axis of the sliding block.

[0012] By clamping the positioning pin on the side wall of the sliding block, the moving distance of the sliding block can be limited, so as to prevent the sliding block from being separated from the tool handle and to prevent the sliding block from closing the through hole.

[0013] In one implementation of this embodiment: a bearing is installed on the positioning pin, the positioning pin is clamped in the positioning groove through the bearing, and the axis of the bearing is perpendicular to the axis of the sliding block.

[0014] The bearing can reduce the friction between the positioning pin and the sliding block, thereby making the sliding block slide more smoothly.

[0015] In one implementation of the present embodiment: the controller includes an air injection sleeve, the air injection sleeve is provided with an air injection hole and an air injection groove, the air injection groove is located on the inner wall of the air injection sleeve, the air injection groove is annular around the axis of the air injection sleeve, and the air injection hole is connected to the air injection groove; the air injection sleeve is rotatably connected to the tool handle, the air injection sleeve rotates relative to the tool handle along the axis of the tool handle, and the air injection groove is connected to the through hole.

[0016] The gas injection sleeve can be connected to an external gas control device, and the gas control device is used to suck the gas. When the single-axis polishing mechanism is working, the tool handle and the gas injection sleeve will rotate relative to each other. The annular gas injection groove is used as a transition, so that the gas injection hole and the through hole can be kept connected at all times, that is, no matter which position the tool handle is rotated to, the gas control device can control the gas volume in the cavity.

[0017] In one implementation of this embodiment: the diameter of the gas injection hole is greater than the width of the gas injection groove.

[0018] The larger diameter of the gas injection hole facilitates connection with the gas control device, and the connection between the gas injection hole and the gas injection groove can position and limit the output end of the gas control device to prevent the output end of the gas control device from extending into the gas injection groove and affecting the rotation of the tool handle.

[0019] In one implementation of the present embodiment: the controller further comprises a positioning ring, the positioning ring is rotatably connected to the tool handle, the positioning ring rotates relative to the tool handle along the rotation axis of the tool handle, and the air injection sleeve is fixedly connected to the positioning ring.

[0020] The positioning ring is used to limit the air injection sleeve to prevent the air injection sleeve from sliding relative to the tool handle along the axis of the tool handle when the tool handle rotates.

[0021] In one implementation of this embodiment: a sealing ring is installed on the gas injection sleeve, and the sealing rings are respectively arranged on both sides of the gas injection groove.

[0022] The provision of the sealing ring can increase the sealing between the air injection sleeve and the tool handle. At the same time, since the sealing ring will rotate relative to the tool handle, the sealing ring needs to have good wear resistance.

[0023] In one implementation of this embodiment: the single-axis polishing mechanism also includes a driving device and a device connecting plate, the driving device is installed on the device connecting plate, and the driving device drives and connects to the tool handle.

[0024] The external equipment connecting plate can be used to conveniently connect the polishing mechanism to various equipment for grinding and polishing. When the polishing equipment is working, the drive device drives the tool handle to rotate, and then the tool handle drives the sliding block and the ejector pin to rotate, thereby performing grinding and polishing.

[0056] Example 1

[0057] Reference Figures 1 to 12 In order to obtain an ideal and stable removal effect, a mechanism with a simpler structure and more stable operation is proposed, and at the same time, a removal effect consistent with that of the previous double-rotation polishing tool can be obtained. The present embodiment provides a single-axis polishing mechanism 001, including a tool handle 100, a polishing assembly 200 and a controller 300. The polishing assembly 200 is slidably connected to the tool handle 100, and the polishing assembly 200 can slide relative to the tool handle 100 along the axis of the tool handle 100. The controller 300 is used to control the position between the tool handle 100 and the polishing assembly 200.

[0058] The single-axis polishing mechanism 001 provided in this embodiment has a simple structure. The polishing tool can be installed on the grinding and polishing assembly 200, and then the grinding and polishing assembly 200 drives the polishing tool to move relative to the tool handle 100. At this time, the polishing tool (not shown in the figure) can be close to or away from the tool handle 100, so that a near-Gaussian removal function that is beneficial to surface shape correction and a removal function that is beneficial to smoothing can be easily obtained, so that its removal effect is consistent with that of the previous double-rotation grinding and polishing tool, and the grinding and polishing assembly 200 can ensure the stability of the polishing tool during operation.

[0059] Among them, the position adjustment between the polishing tool and the tool handle 100 should be performed before the grinding and polishing action. After the position between the polishing tool and the tool handle 100 is adjusted, the position between the polishing tool and the tool handle 100 should be kept unchanged, that is, when performing the grinding and polishing action, the polishing tool will rotate with the tool handle 100, but will not move relative to the tool handle 100.

[0060] See also Figure 4 and Figure 5 The handle 100 is provided with a slide groove 110, a through hole 130 and a positioning hole 120. The slide groove 110 extends along the axis of the handle 100. The through hole 130 is connected to the slide groove 110. The positioning hole 120 is also connected to the slide groove 110. The through hole 130 and the positioning hole 120 are arranged at intervals along the axis of the handle 100. The through hole 130 is located at one end of the handle 100 away from the polishing assembly 200. The diameter of the slide groove 110 can be set to 5 mm.

[0061] See 9 to Fig.11 The polishing assembly 200 includes a sliding block 210 and an ejector pin 220. The diameter of the sliding block 210 should be the same as the diameter of the slide groove 110, so that it is easy to form a seal and the sliding block 210 and the tool handle 100 slide smoothly. The ejector pin 220 and the sliding block 210 are detachably connected. In this embodiment, the sliding block 210 and the ejector pin 220 can be screwed. A threaded hole 212 is provided at one end of the sliding block 210, and an external thread 221 matching the threaded hole 212 is provided at one end of the ejector pin 220. In this way, the ejector pin 220 and the sliding block 210 can be disassembled and installed more conveniently and quickly. During use, when installing different polishing tools, different ejector pins 220 may need to be replaced due to different structures, and the installation of the sliding block 210 and the tool handle 100 is relatively complicated and delicate. Therefore, it is more convenient to only replace the ejector pin 220, and it will not affect the accuracy of polishing. By driving the ejector pins 220 of different configurations with a single axis, a near-Gaussian removal function that is beneficial to surface error correction and a removal function that is beneficial to surface mid- and high-frequency smoothing can be obtained.

[0062] See also Fig.11The above description of this embodiment is described by taking the ejector pin 220 as an example. In other implementations of this embodiment, the ejector pin 220 can also be set as an eccentric ejector pin or a ball head ejector pin, etc.

[0063] The other end of the sliding block 210 is slidably connected to the tool handle 100, and the sliding block 210 is clamped in the sliding groove 110. The end of the sliding block 210 and the sliding groove 110 form a chamber 500, and the through hole 130 is connected to the chamber 500; a positioning groove 211 is also provided on the side wall of the sliding block 210, and the positioning groove 211 is correspondingly provided to the positioning hole 120.

[0064] Among them, the positioning holes 120 can be set to two, and the two positioning holes 120 are set at intervals around the axis of the handle 100. As a preferred embodiment, the two positioning holes 120 can be set on the same diameter of the handle 100, so that the force on the sliding block 210 is more symmetrical, so that the sliding block 210 can slide more smoothly. Of course, setting two positioning holes 120 and setting them on the same diameter of the handle 100 is only one embodiment of this embodiment. In other embodiments, setting the positioning holes 120 to one or more and arranging them in an asymmetrical manner is also possible.

[0065] The sliding block 210 and the tool handle 100 can be connected through a positioning pin 600. The positioning pin 600 is inserted from the positioning hole 120 and then clamped in the positioning groove 211. The positioning groove 211 extends along the axial direction of the sliding block 210, and the length of the positioning groove 211 should be greater than the diameter of the positioning pin 600, and the width of the positioning groove 211 is equal to the diameter of the positioning pin 600. In this way, the sliding block 210 can be restricted by the positioning pin 600 to prevent the sliding block 210 from rotating along its axial line relative to the tool handle 100, and the length of the positioning groove 211 is greater than the diameter of the positioning pin 600, which allows the sliding block 210 to slide smoothly along its axial line relative to the tool handle 100.

[0066] The two end surfaces of the positioning groove 211 along its length direction should be spaced apart from the two end surfaces of the sliding block 210 , so as to prevent the sliding block 210 from sliding out of the range of the positioning pin 600 .

[0067] See also Fig.12In one implementation of this embodiment, an internal thread can be provided in the positioning hole 120, and the positioning pin 600 is divided into a first section 610 and a second section 620, the first section 610 and the second section 620 are coaxially arranged, and a thread is provided on the second section 620, and the second section 620 is screwed into the positioning hole 120, so that the positioning pin 600 can be fixed, and a pattern can be provided on the end surface of the second section 620 away from the first section 610 to facilitate the screwing of the positioning pin 600; the first section 610 is inserted into the positioning groove 211, and the diameter of the first end can be smaller than the diameter of the second section 620. A more preferred way is to set the positioning hole 120 as an M5 thread. Since the M5 thread is a standard processing thread, the processing tool is easier to find and does not need to be customized again, thereby saving processing costs.

[0068] A bearing may also be installed on the positioning pin 600, and the bearing may be installed on the first section 610. The positioning pin 600 is clamped in the positioning groove 211 through the bearing, and the axis of the bearing is perpendicular to the axis of the sliding block 210. The bearing can reduce the friction between the positioning pin 600 and the sliding block 210, so that the sliding block 210 can slide more smoothly.

[0069] See also Figure 3 , the controller 300 is connected to the chamber 500 through the through hole 130, and the controller 300 is used to control the size of the chamber 500. The controller 300 can inflate the chamber 500, or it can extract the gas in the chamber 500. When the controller 300 inflates the chamber 500, the pressure in the chamber 500 increases, which pushes the polishing assembly 200 outward, and the distance between the polishing tool and the handle 100 increases. When the controller 300 extracts the gas in the chamber 500, the pressure in the chamber 500 decreases, which sucks the polishing assembly 200 inward, and the distance between the polishing tool and the handle 100 decreases.

[0070] See also Figures 6 to 8The controller 300 includes an air injection sleeve 320 and a positioning ring 310. The air injection sleeve 320 is provided with an air injection hole 321 and an air injection groove 322. The air injection groove 322 is located on the inner wall of the air injection sleeve 320. The air injection groove 322 is annular around the axis of the air injection sleeve 320, and the air injection hole 321 is connected with the air injection groove 322. The air injection sleeve 320 is rotatably connected with the tool handle 100. The air injection sleeve 320 rotates relative to the tool handle 100 along the axis of the tool handle 100, and the air injection groove 322 is connected with the through hole 130. The gas injection sleeve 320 can be connected to a gas control device (not shown in the figure) to pump gas. When the single-axis polishing mechanism 001 is working, the tool handle 100 and the gas injection sleeve 320 will rotate relative to each other. The transition of the annular gas injection groove 322 can keep the gas injection hole 321 and the through hole 130 connected at any time, that is, the gas control device can control the gas volume in the cavity no matter which position the tool handle 100 rotates to. Among them, the gas control device can be a cylinder, of course, other gas compression devices can also be used.

[0071] The diameter of the gas injection hole 321 can be larger than the width of the gas injection groove 322. The larger diameter of the gas injection hole 321 facilitates connection with the gas control device, and the connection between the gas injection hole 321 and the gas injection groove 322 can position and limit the output end of the gas control device to prevent the output end of the gas control device from extending into the gas injection groove 322 and affecting the rotation of the handle 100. In one implementation of this embodiment, the diameter of the gas injection hole 321 can be set to 5 mm, and the width of the gas injection groove 322 can be set to 4 mm.

[0072] The positioning ring 310 is rotatably connected to the handle 100, and the positioning ring 310 rotates relative to the handle 100 along the rotation axis of the handle 100, and the gas injection sleeve 320 is fixedly connected to the positioning ring 310. The positioning ring 310 is used to limit the gas injection sleeve 320 to prevent the gas injection sleeve 320 from sliding relative to the handle 100 along the axis of the handle 100 when the handle 100 rotates.

[0073] A sealing ring 323 is installed on the gas injection sleeve 320, and a sealing ring 323 is respectively arranged on both sides of the gas injection groove 322. The arrangement of the sealing ring 323 can increase the sealing performance between the gas injection sleeve 320 and the handle 100. At the same time, since the sealing ring 323 will rotate relative to the handle 100, the sealing ring 323 needs to have good wear resistance.

[0074] The uniaxial polishing mechanism provided in this embodiment is used as follows:

[0075] The ejector pin 220 is mounted on the sliding block 210 and drives the polishing tool to perform polishing during the machining process;

[0076] The sliding block 210 is assembled in the slide groove 110 of the tool handle 100, and the sliding block 210 can move back and forth along the slide groove 110 relative to the tool handle 100, and the moving range of the sliding block 210 is limited by the positioning pin 600 and the positioning groove 211;

[0077] The air injection sleeve 320 is installed above the tool handle 100, and the air injection sleeve 320 is connected to the slide groove 110. When the air injection sleeve 320 injects gas into the slide groove 110, the sliding block 210 drives the polishing tool to move away from the tool handle 100. When the air injection sleeve 320 sucks the gas in the slide groove 110, the sliding block 210 drives the polishing tool to move toward the tool handle 100. When the air injection sleeve 320 maintains a stable pressure, the position of the sliding block 210 can be fixed. At this time, the relative position between the polishing tool and the tool handle 100 is also fixed.

[0078] The single-axis polishing mechanism 001 provided in this embodiment has a simple structure, good assembly accuracy, and can be used for any CNC machine tools (robotic machine tools, CNC machine tools); the single-axis polishing mechanism 001 provided in this embodiment is a single-axis drive processing, has high stability during processing, and can obtain a better removal function; the single-axis polishing mechanism 001 provided in this embodiment can obtain a near-Gaussian removal function that is beneficial to surface shape correction and a removal function that is beneficial to smoothing by changing the ejector pin.

[0079] See also Figure 1 and Figure 2 In one implementation of the present embodiment, a transfer sleeve 400 may be provided outside the knife handle 100 and the controller 300 , and the transfer sleeve 400 may facilitate the connection between the knife handle 100 and the driving device 002 .

[0080] In order to obtain an ideal and stable removal effect, this embodiment proposes a polishing mechanism 001 with a simpler structure and more stable operation, and can obtain the same removal effect as the previous double-rotation polishing tool. By driving the ejector pins 220 of different configurations with a single axis, a near-Gaussian removal function that is beneficial to surface error correction and a removal function that is beneficial to surface mid-high frequency smoothing can be obtained. The polishing mechanism 001 provided in this embodiment has a simple structure and can achieve good assembly accuracy, and can be basically used with all CNC machine tools (robot machine tools, CNC machine tools).

[0081] See also Fig.13 The single-axis polishing mechanism 001 provided in this embodiment also includes a driving device 002 and a device connecting plate 003 . The driving device 002 is installed on the device connecting plate 003 , and the driving device 002 drives the connecting tool handle 100 .

[0082] The external device connecting plate 003 can conveniently connect the polishing mechanism 001 to various devices for grinding and polishing.
