Description

Technical Field

[0001] The present application relates to the technical field of optical component polishing, and more specifically, to a polishing tool and polishing equipment for a spherical optical component. Background Art

[0002] In the polishing process of spherical optical components, there is a spherical optical component including: an edge ring area, and an intermediate curved surface area surrounded by the edge ring area. The intermediate curved surface area is concave or convex, while the edge ring area is a plane. Thus, the spherical optical component forms a product with one side surface being a concave platform or a convex platform.

[0003] Taking a spherical optical component with a middle concave surface in the middle arc surface area and an edge ring area as an edge platform as an example, when polishing the edge platform of a conventional spherical optical component, a flat die disc is usually used to grind and polish the finished product, that is, the surface of the edge platform is polished directly by the flat grinding disc contacting the edge platform. However, for convex platform products and spherical optical components with a large concave radius (when the opening angle of the concave surface is less than 1°, the sagittal height of the concave spherical surface is less than 0.1, or even less than 0.01, and the middle arc surface area looks very close to a plane to the naked eye), if a flat die disc is used to polish the edge platform around the concave surface, the polished surface of the middle concave surface in the center (the surface of the middle arc surface area) will be scratched, resulting in poor finish.

[0004] Therefore, the prior art still needs to be improved and developed. Utility Model Content

[0006] To achieve the above purpose, the technical solution adopted in this application is:

[0007] On the one hand, the present application provides a polishing tool for a spherical optical component, which is used to polish an edge annular area of ​​the optical component, wherein the optical component also has an intermediate arc surface area surrounded by the edge annular area, wherein the polishing tool comprises: a clamping tool and a polishing mold, wherein the clamping tool and the polishing mold are used to be mounted on a polishing machine body and rotate relatively;

[0008] The clamping tooling includes: a ferrule, on which a limiting groove is provided, and the limiting groove is used to limit the movement of the optical component in the horizontal direction;

[0009] A pushing piece is arranged in the ferrule and applies a thrust to the optical piece so that the optical piece abuts against the polishing mold;

[0010] The polishing mold comprises: a middle polishing part and a peripheral polishing part, wherein the middle polishing part and the peripheral polishing part are spaced apart to form a clearance groove;

[0011] The middle cambered area is located in the air-avoiding groove, and the middle polishing portion and the outer polishing portion are used for polishing the edge annular area.

[0012] In an optional embodiment, the middle polishing portion includes: a middle boss, the middle boss is a round table;

[0013] The peripheral polishing part comprises: a ring platform, which is arranged around the middle boss, and the middle boss is located at the center of the ring platform.

[0014] In an optional embodiment, the polishing mold is mounted on the polishing machine body via a mold base;

[0015] The polishing mold and the mold base are clearance-matched and are fastened and connected by bolts.

[0016] In an optional embodiment, the end surface of the ferrule facing the polishing mold is set as an inclined surface;

[0017] Along the radial direction of the ferrule and in the direction away from the center of the ferrule, the distance between the inclined surface and the end surface of the polishing mold gradually increases.

[0018] In an optional embodiment, the clamping tool further includes: a clamping base, and the clamping sleeve is connected to the clamping base;

[0019] An inflatable airway is arranged in the bottom bracket of the clamp, and the pushing piece is located at one side of the outlet of the inflatable airway and is pushed by the gas in the inflatable airway.

[0021] A bearing boss is arranged on the bottom bracket of the clamp, a sleeve ring groove is opened on the bearing boss, and the flexible sleeve wraps the bearing boss and makes the tightening edge be embedded in the sleeve ring groove.

[0022] In an optional embodiment, the flexible sleeve is a rubber sleeve.

[0023] In an optional embodiment, the diameter of the outlet of the inflation channel on the side facing away from the polishing mold is smaller than the diameter of the outlet on the side facing the polishing mold.

[0024] In an optional embodiment, the ferrule is mounted on a fixture base, and the fixture base is connected to the ferrule through a top screw on the side wall of the ferrule.

The processed middle arc surface area is located in the air-avoiding groove. Since the optical component does not move in the horizontal direction and the polishing mold does not contact the middle arc surface area of ​​the optical component, the surface shape and finish of the middle arc surface area will not be affected, and the platform processing accuracy is well guaranteed. Especially when polishing the annular area plane of the edge of a large-radius spherical optical component, the middle arc surface area can also be avoided when the sagittal height of the middle arc surface area is small, so that the middle polishing part and the outer polishing part will not scratch the arc surface area in the center, avoiding poor finish.

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component.

The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features.

[0038] The specific explanations of the terms in this embodiment are as follows:

[0039] Spherical optical component: at least one side of the surface has a middle curved area and an edge annular area, the middle curved area is a concave spherical surface or a convex spherical surface, the edge annular area is a plane, and the middle curved area is surrounded by the edge annular area. Thus, the spherical optical component forms a product with the upper surface or / and the lower surface being a concave platform or a convex platform.

[0040] Large radius concave spherical surface: refers to a spherical optical component with a concave or convex spherical surface in the middle arc area with an opening angle less than 1° and a sagittal height less than 0.1mm.

[0041] Embodiment 1

[0042] like Figure 1 , Figure 2 As shown, this embodiment proposes a polishing tool for a spherical optical component, which is used to polish the edge annular area 11 of the optical component 10. For the convenience of structural description, a spherical optical component 10 with a concave surface on the upper surface is used as an example for detailed description. The spherical optical component 10 has a middle arc surface area 12 surrounded by the edge annular area 11. The middle arc surface area 12 is a middle concave surface, and the middle concave surface can be a large-radius concave spherical surface. The edge annular area 11 is a plane. The polishing tool of this embodiment is used to polish the edge annular area 11, and the finish of the middle concave surface of the spherical optical component 10 will not be destroyed, so as to achieve stable processing and ensure the central required light aperture of the spherical optical component 10.

[0043] like Figure 1 , Figure 2 As shown, the polishing tool for the spherical optical component of this embodiment mainly includes: a clamping tool 100 and a polishing mold 200. The clamping tool 100 and the polishing mold 200 are used to be installed on the polishing machine body and rotate relatively. The clamping tool 100 can be installed below the polishing mold 200. The clamping tool 100 is used to clamp the optical component 10 to be processed, and the polishing mold 200 is used to polish the edge annular area 11 of the optical component 10. The polishing method of the polishing machine body can be in the following forms: by driving the polishing machine body, the clamping tool 100 can drive the optical component 10 to rotate, and the polishing mold 200 can also rotate, so that the clamping tool 100 and the polishing mold 200 can rotate relatively to achieve the polishing of the optical component 10. Or by driving the polishing machine body, the clamping tool 100 can drive the optical component 10 to rotate, while the polishing mold 200 does not rotate, so as to achieve the polishing of the optical component 10. Alternatively, the clamping fixture 100 and the optical component 10 are not rotated, and the polishing mold 200 is rotated by driving the polishing machine body, thereby achieving polishing of the optical component 10.

[0044] like Figure 1 , Figure 3As shown, the clamping tool 100 mainly includes: a ferrule 110 and a push piece 120. The clamping tool 100 is installed on the polishing machine body in the up-down direction. The ferrule 110 extends a predetermined length in the up-down direction. A limiting groove 111 is provided on the ferrule 110. The inner wall size of the limiting groove 111 matches the outer wall size of the processed optical component 10. Therefore, the limiting groove 111 is used to limit the horizontal movement of the optical component 10. When the optical component 10 is installed in the limiting groove 111, the optical component 10 will not move in the horizontal direction. If the precision is relatively low, the size of the limiting groove 111 can also be slightly larger than the size of the optical component 10, as long as it is ensured that the middle concave surface or middle convex surface (middle arc surface) of the optical component 10 does not contact the working part of the polishing mold 200 within the limited range of the horizontal direction of the optical component 10. The pushing piece 120 is arranged in the ferrule 110, and applies a thrust to the optical component 10 so that the optical component 10 is pressed against the polishing mold 200. During the polishing process, the pushing piece 120 applies a thrust to the optical component 10, so that the edge annular area 11 of the optical component 10 is in stable contact with the working part of the polishing mold 200 and generates a certain friction force, thereby smoothly performing polishing.

[0045] like Figure 1 , Figure 2 , Figure 3 As shown, the polishing mold 200 mainly includes: an intermediate polishing part 210 and a peripheral polishing part 220. The intermediate polishing part 210 and the peripheral polishing part 220 are spaced apart to form an air-avoiding groove 230. The intermediate polishing part 210 and the peripheral polishing part 220 are used to polish the edge ring. The groove width of the air-avoiding groove 230 needs to take into account the caliber of the intermediate arc surface area 12 of the optical component 10. The groove width of the air-avoiding groove 230 should be greater than or equal to the caliber of the intermediate arc surface area 12, so that during the polishing process, the intermediate arc surface area 12 of the optical component 10 is located in the air-avoiding groove 230, and the intermediate polishing part 210 and the peripheral polishing part 220 will not contact the intermediate arc surface area 12 of the optical component 10, so as not to affect the surface quality of the intermediate arc surface area 12.

[0046] A polishing tool for a spherical optical component of the present embodiment is used to polish the edge annular area 11 (plane) of the optical component 10, which also has a high polishing finish requirement. During the polishing process, the polishing tool of the present application limits the optical component 10 by the clamping sleeve 110 of the fixture 100, so that the position of the polished edge annular area 11 is basically unchanged during the polishing process. Then, the optical component 10 is thrusted by the action of the push piece 120 so that the edge annular area 11 of the optical component 10 abuts against the middle polishing part 210 and the outer polishing part 220 of the polishing mold 200, so that the edge annular area 11 is smoothly polished. The processed middle concave surface is located in the air-avoiding groove 230. Since the optical component 10 does not move in the horizontal direction and the polishing mold 200 does not contact the surface of the middle concave surface of the optical component 10, the surface shape and finish of the middle concave surface will not be affected, and the platform processing accuracy is well guaranteed to ensure the requirements of the center required light aperture. Especially when the arrow height of the middle concave surface is small, the middle concave surface can be avoided, so that the middle polishing part 210 and the outer polishing part 220 will not scratch the middle concave area at the center, avoiding poor finish.

[0047] like Figure 1 , Figure 2 As shown, further, the middle polishing part 210 in this embodiment specifically includes a middle boss 211, and the middle boss 211 is a truncated cone. The outer polishing part 220 includes a ring platform 221, and the ring platform 221 is arranged around the middle boss 211, and the middle boss 211 is located at the center of the ring platform 221. The ring platform 221 surrounds the middle boss 211 in a whole circle, so that the ring platform 221 and the middle boss 211 have a connected lower surface, and the lower surface is plane-polished to ensure the polishing effect.

[0048] like Figure 3 , Figure 4 As shown, further, the polishing mold 200 in this embodiment is installed on the polishing machine body through the mold base 250. A docking platform 251 is set in the middle of the mold base 250, and a docking hole 240 is set on the back of the corresponding polishing mold 200. Through the docking hole 240 and the docking platform 251, a clearance fit can be adopted to enable the polishing mold 200 and the mold base 250 to be quickly docked, and the polishing mold 200 and the mold base 250 are then fastened and connected by bolts, and the threaded holes of the bolts are parallel to the central axis of the mold base 250. The connection process of the polishing mold 200 and the polishing machine body is more convenient and quick.

[0049] like Figure 3 , Figure 4As shown, further, the end surface of the ferrule 110 in this embodiment facing the polishing mold 200 is set as an inclined surface 112, and the distance between the inclined surface 112 and the end surface of the polishing mold 200 gradually increases along the radial direction of the ferrule 110 and away from the center of the ferrule 110. Therefore, the inclined surface 112 is a conical surface, and the diameter of the upper end of the conical surface is smaller than the diameter of the lower end, so that the position of the ferrule 110 away from the optical component 10 is lower than the surface of the edge annular area 11 of the optical component 10, so that it will not touch the working surface of the upper polishing mold 200, and will not interfere with the lower surface (working surface) of the upper middle polishing part 210 and the lower surface (working surface) of the peripheral polishing part 220, so that the polishing process of the edge annular area 11 of the optical component 10 is more stable.

[0050] like Figure 1 , Figure 3 , Figure 4 As shown, further, the clamping tool 100 in this embodiment also includes: a fixture base 130, which is connected to the polishing machine body in the up-down direction. The ferrule 110 is connected to the upper end of the fixture base 130, and an air duct 131 is provided in the fixture base 130. The air duct 131 has an outlet 134 facing upward, and the pusher 120 is located above the outlet 134 of the air duct 131, and the pusher 120 is pushed by the gas in the air duct 131. When polishing is required, the pusher 120 is pushed or deformed upward under the action of air pressure, so that the optical member 10 is pushed in the up-down direction, so that the edge annular area 11 of the optical member 10 that needs to be polished abuts against the lower surface of the middle polishing part 210 and the lower surface of the peripheral polishing part 220. The push piece 120 is driven by air pressure. Under the condition of ensuring the stability of air pressure, the thrust applied to the push piece 120 is stable, and the thrust applied by the push piece 120 to the optical component 10 is relatively consistent, which is convenient for controlling the polishing size and accuracy.

[0051] like Figure 3 , Figure 4As shown, further, the push piece 120 in this embodiment specifically includes: a flexible sleeve 121, a covering cavity 122 is provided in the flexible sleeve 121, and a tightening edge 123 is provided at the opening of the covering cavity 122, so the caliber of the tightening edge 123 is smaller than the caliber of the covering cavity 122. A bearing boss 132 is provided at the upper end of the clamp base 130, and a sleeve ring groove 133 is provided on the bearing boss 132. The flexible sleeve 121 can be sleeved on the bearing boss 132 and wrap the bearing boss 132. The tightening edge 123 is embedded in the sleeve ring groove 133, so that the connection between the flexible sleeve 121 and the bearing boss 132 is more secure. Under the action of air pressure, the lower end of the flexible sleeve 121 is not easy to be separated from the bearing boss 132, thereby improving the stability of use. The flexible sleeve 121 in this embodiment can be a rubber sleeve, which has low cost, mature production technology, durability, good elasticity, and stronger practicality.

[0052] like Figure 3 , Figure 4 As shown, further, the caliber of the outlet 134 of the inflatable air channel 131 in this embodiment is smaller on the side away from the polishing mold 200 than on the side facing the polishing mold 200. The outlet 134 of the inflatable air channel 131 adopts a bell mouth, so that the gas filled in is dispersed at the outlet 134 and exerts pressure on the top inner wall of the entire covering cavity 122, so that the top of the flexible sleeve 121 is more evenly stressed, and the top of the flexible sleeve 121 pushes the optical component 10 as a whole, and the thrust distribution is more even, which is conducive to ensuring the processing accuracy.

[0053] like Figure 1 , Figure 3 As shown, further, the ferrule 110 in this embodiment is sleeved on the fixture base 130, and the fixture base 130 is connected by a top screw 140 on the side wall of the ferrule 110, and the threaded hole of the top screw 140 is perpendicular to the central axis of the fixture base 130. The ferrule 110 is directly sleeved on the outer wall of the fixture base 130, which is convenient for installation. The ferrule 110 and the fixture base 130 are stably connected by fixing with the top screw 140, and are convenient for disassembly and installation, thereby optimizing the structure.

[0054] Embodiment 2

[0055] This embodiment provides a polishing device, which includes a polishing machine body and a polishing tool for a spherical optical component as described above. The polishing machine body includes an upper shaft and a lower shaft, the upper shaft is rotatably arranged or / and the lower shaft is rotatably arranged, a clamping tool is connected to the lower shaft, and a polishing mold is connected to the upper shaft. The polishing machine body can use CNC polishing equipment, which is convenient for automated control and realizes batch and efficient polishing.

[0056] The conventional driving mode of the polishing machine body is: the lower shaft of the polishing machine body is fixed and the upper shaft rotates; therefore, when the polishing equipment is polishing, the lower shaft supports the clamping tooling to keep the optical part fixed, while the upper shaft drives the polishing mold to rotate, thereby achieving polishing.

[0057] In addition, in order to increase the polishing efficiency, the driving mode of the polishing machine body can also be: the lower shaft and the upper shaft of the polishing machine body rotate, and the rotation directions of the two are opposite; therefore, when the polishing equipment is polishing, the lower shaft drives the clamping tooling to rotate forward, thereby causing the optical part to rotate forward; the upper shaft drives the polishing mold to rotate in the opposite direction, thereby achieving efficient polishing.

[0058] In summary, the polishing tool and polishing equipment for spherical optical parts proposed in this application can polish the edge annular area of ​​the optical parts, which also has high requirements for polishing finish, and will not affect the surface shape and finish of the central concave spherical surface during the polishing process. In particular, when polishing the edge annular area plane of a large-radius spherical optical part, if the sagittal height of the middle arc area is small, the middle arc area can be avoided, so that the middle polishing part and the outer polishing part will not scratch the concave area in the center, avoiding poor finish. And the processing accuracy is higher, which can well guarantee the platform processing accuracy.

[0059] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
