Description

Technical Field

[0001] This invention relates to the field of optical mirror manufacturing technology, specifically to a milling apparatus and method for optical aspherical mirrors. Background Technology

[0002] Aspherical lenses differ from ordinary spherical lenses in their surface curvature. To achieve thinner lenses, the surface curvature needs to be altered. Previously, spherical designs increased aberrations and distortion, resulting in noticeable blurry images, distorted vision, and a narrow field of view. The aspherical design corrects these issues, resolving problems like distorted vision, while simultaneously making the lenses lighter, thinner, and flatter. Furthermore, it maintains excellent impact resistance, ensuring safe use for the wearer.

[0003] In the prior art, when milling an aspherical mirror, the mirror needs to be fixed and its rotation controlled, and the direction and angle of the milling tool need to be adjusted so that the aspherical mirror can be milled at any position and angle with precision.

[0004] However, during the milling process of aspherical mirrors, the milling device operates at different angles to different positions on the mirror surface, requiring repeated adjustments to the angle of the milling cutter, which is inefficient and affects the production efficiency of optical aspherical mirrors. Summary of the Invention

[0005] The purpose of this invention is to provide a milling apparatus and method for optical aspherical mirrors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A milling apparatus for optical aspherical mirrors, comprising:

[0008] A milling device for optical aspherical mirrors includes a housing, a water tank is disposed below the housing, the housing and the water tank are separated vertically, and a water trough is disposed inside the water tank;

[0009] The water tank contains coolant used in milling operations.

[0010] A rotating assembly is rotatably mounted on the bottom of the housing, and an adjustment plate capable of rotating within a certain angle is mounted above the rotating assembly.

[0011] The mirror surface is flipped during the processing by adjusting the rotation of the dial.

[0012] The rotating assembly is mounted on the first drive shaft, and a limiting wheel is rotatably mounted on the top of the first drive shaft. The top of the limiting wheel is fixed to the adjusting disc, and the adjusting disc achieves the flipping function between itself and the rotating assembly through the structure of the limiting wheel.

[0013] The first drive shaft is driven and mounted on a bidirectional motor. The other end of the bidirectional motor is connected to a second drive shaft. The second drive shaft rotates synchronously with the first drive shaft. The rotation of the second drive shaft drives the guide pipe to deliver coolant upward.

[0014] The limit wheel controls the adjustment disc to flip on the first drive shaft while preventing it from rotating back.

[0015] The adjusting disk is fixedly equipped with a positioning component for fixing the mirror surface. The adjusting disk controls the mirror surface to be flipped and adjusted during rotation through the positioning component.

[0016] The mirror is mounted on the adjustment plate using a positioning component.

[0017] The housing is also equipped with a milling assembly for milling the mirror surface.

[0018] Furthermore, the outer side of the housing is provided with a housing door, and the housing door is provided with an observation glass for easy observation of the mirror processing progress. The inner wall of the bottom of the housing facing the housing door is fixed with a baffle plate to prevent the coolant at the bottom of the housing from flowing out. The outer side of the water tank is also provided with a water tank door. The bottom of the housing is provided with a flow channel communicating with the water tank. Below the flow channel is a collection channel. The collection channel is a filter screen structure. The collection channel is slidably installed on the top of the water tank via a slide rail assembly.

[0019] The filter structure of the collection tank filters and intercepts the debris from the mirror processing, preventing it from entering the water tank. At the same time, the sliding installation structure of the collection tank makes it easy to pull it out so that the filtered mirror debris can be removed and reused.

[0020] Furthermore, a gap is left between the rotating assembly and the adjusting disk to allow the adjusting disk to flip. Rotary wheels are rotatably mounted on the upper sides of both sides of the rotating assembly. A first telescopic rod is mounted above one of the rotating wheels, and the upper end of the first telescopic rod is mounted on the inner wall of the adjusting disk. The upper part of the rotating wheel on the other side is connected to the piston rod of the cylinder, and the cylinder is also mounted on the inner wall of the adjusting disk.

[0021] The rotation direction of the adjusting plate is controlled by the cylinder. When the piston rod extends, the adjusting plate rotates counterclockwise. When the piston rod retracts, the adjusting plate rotates clockwise.

[0022] Furthermore, a movable groove is provided below the center of the adjusting disc, and a limiting wheel is fixedly connected to the center of the movable groove. A first connecting block is fixedly connected to the top of the first drive shaft. The limiting wheel is rotatably installed in the center of the first connecting block. A slot is provided on the side wall of the limiting wheel, and several limiting blocks are provided on the lower outer wall of the slot. The cross-section of the limiting block is triangular. A locking pin is vertically slidably connected to the top of the first drive shaft, and the end of the locking pin is engaged between the right-angled sides of two adjacent limiting blocks.

[0023] Furthermore, a spring is provided below the locking post, one end of the spring is fixedly connected to the lower part of the locking post, and the other end of the spring is fixedly connected to the inner wall of the first transmission shaft. A pull block is fixedly connected to one side of the lower part of the locking post, the pull block extends out of the first transmission shaft, and is vertically slidably connected to the first transmission shaft.

[0024] The mirror is rotated and flipped by a cylinder. During processing, the mirror is flipped in one direction so that it can be milled from the outside to the inside. The locking structure between the limit block and the locking post ensures that the adjustment plate can only rotate in one direction. When it needs to be reset, the pull block is pulled down so that the locking post retracts into the first drive shaft, which can reset the adjustment plate.

[0025] Furthermore, a positioning component is fixedly connected to the upper axis of the adjusting disc. The positioning component is a hollow structure, and several evenly distributed bolts are provided on the side wall of the positioning component.

[0026] One side of the mirror is covered with a protective layer, and the other side of the protective layer is formed into a metal base by metal casting. A second connecting block is fixedly connected to the bottom of the metal base. The side wall of the second connecting block is provided with a plurality of positioning holes corresponding to the bolts. The bolts are threadedly connected to the positioning holes.

[0027] The metal base and connecting block are formed by hot-melt casting of metal to fix the mirror onto the positioning component.

[0028] Furthermore, a first gear is installed at the lower end of the second drive shaft, and a second gear is provided on the same side of the first gear at the same level. The first gear and the second gear mesh and drive each other. A worm is fixedly installed on the shaft of the second gear. The worm rotates inside the guide pipe, driving the water flow in the guide pipe to rise.

[0029] The relative rotation of the worm gear inside the guide tube guides the coolant upwards, thus achieving coolant recycling.

[0030] Furthermore, the guide pipe connects the housing and the water tank and is fixed at the connection between the two. The guide pipe is fixed at the connection between the housing and the water tank. The lower end of the guide pipe extends into the water tank, and there is a gap between the lower end of the guide pipe and the top of the second gear. The upper end of the guide pipe is connected to the upper water tank. Several water injection pipes facing the mirror milling position are installed on the upper water tank.

[0031] Coolant is injected into the milled parts of the mirror surface through the water injection pipe to cool the milled parts, prevent overheating that could damage the mirror surface and the milling tool, increase the lubrication of the machining process, and wash away some of the debris.

[0032] Furthermore, an adjustment assembly is installed on the top inner wall of the housing. The adjustment assembly can move horizontally in multiple directions via a cross-shaped guide rail. The milling assembly is fixedly installed below the adjustment assembly. The milling assembly can move horizontally in any direction via the adjustment assembly. A rotatable and liftable milling cutter is installed below the milling assembly.

[0033] The adjustment component controls the milling component to move arbitrarily in the horizontal direction, and the milling component controls the rotation of the milling cutter and its movement in the vertical direction, so that the mirror surface can be milled at any angle and position.

[0034] A milling method for optical aspherical mirrors includes the following steps:

[0035] S1: Attach a protective layer to one side of the mirror, and form a metal base and connecting block by hot-melting metal casting on the protective layer. Open the box and water tank through the box door and water tank door. Insert the connecting block into the positioning assembly, rotate the bolt to screw the bolt into the positioning hole of the connecting block, thereby fixing the mirror on the adjustment plate. After injecting coolant into the water tank, close the box door and water tank door.

[0036] S2: Start the bidirectional motor so that the first drive shaft drives the rotating component to rotate, that is, the mirror rotates. The position of the milling component is controlled by adjusting the component, and the milling cutter is controlled to rotate and descend to mill the side of the mirror that is not covered by the protective layer.

[0037] S3: During the machining process, according to the requirements of the aspherical surface of the mirror, the piston rod of the cylinder is controlled to extend and retract, so that the adjustment plate is flipped to one side, that is, it is tilted while driving the mirror to rotate. The limit wheel controls the adjustment plate to flip while preventing the adjustment plate from rotating back, which would cause the machining position of the milling component to deviate. The mirror is milled from the outside to the center, and the height of the milling tool is controlled by the milling component to realize the aspherical milling of the mirror.

[0038] S4: During the mirror milling process, the second drive shaft at the other end of the bidirectional motor controls the rotation of the first gear. Due to its meshing transmission with the second gear, it drives the worm to rotate in the guide tube, which guides the water in the water tank upward to the upper water tank. The coolant is then injected into the mirror milling position through the water injection pipe to cool and lubricate the mirror and the milling tool.

[0039] S5: Simultaneously, the mirror debris and coolant generated during processing enter the bottom of the tank and are blocked by the baffle to prevent them from flowing out. The coolant and debris are then passed through the flow channel into the water tank. The debris will enter the collection tank for filtration and collection, so that the coolant can be recycled and the mirror debris is prevented from being carried into the circulation.

[0040] S6: After the mirror finish is completed, open the water tank and the tank body, take out the mirror, and pull out the collection tank. Recycle the collected mirror debris and proceed with the processing of the next mirror. If you stop using it, you can drain the coolant from the water tank.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] 1. The present invention uses a limiting wheel structure to enable the adjustment disk to rotate on the rotating assembly, thereby causing the mirror to rotate during rotation. Furthermore, the cylinder structure makes the rotation angle of the adjustment disk controllable, so as to precisely process any position on the surface of the aspherical mirror from different angles. This avoids the need for milling cutters to make reciprocating angle and position adjustments during the milling process of the aspherical mirror, thus accelerating the production efficiency of optical aspherical mirrors.

[0043] 2. Through the synchronous rotation of the first drive shaft and the second drive shaft, the first gear and the second gear mesh and rotate during the mirror surface processing, controlling the worm to rotate in the guide tube, and conveying the coolant in the water tank upward and introducing it, so as to realize the recycling of the coolant;

[0044] 3. The structure of the limiting wheel allows the adjusting disc to rotate on the first drive shaft. The limiting block structure on its outer wall, together with the locking pin, enables the adjusting disc to rotate in one direction during the processing. This avoids the problem of rotation during the mirror processing and rotation, which would cause deviation in the milling position and affect the mirror forming qualification rate.

[0056] The water tank 22 contains coolant for milling operations.

[0057] Rotating component 3 is rotatably mounted on the bottom of the housing 1, and an adjusting plate 31 capable of flipping within a certain angle is mounted on the top of the rotating component 3;

[0058] The mirror 6 is controlled to rotate during the processing by adjusting the rotation of the adjustment plate 31.

[0059] The rotating assembly 3 is mounted on the first transmission shaft 34. A limiting wheel 4 is rotatably mounted on the top of the first transmission shaft 34. The top of the limiting wheel 4 is fixed to the adjusting disk 31. The adjusting disk 31 achieves the flipping function between itself and the rotating assembly 3 through the structure of the limiting wheel 4.

[0060] The limit wheel 4 controls the adjustment disc 31 to flip on the first transmission shaft 34 while preventing it from rotating.

[0061] The adjusting disk 31 is fixedly equipped with a positioning component 5 for fixing the mirror 6. The adjusting disk 31 controls the mirror 6 to be flipped and adjusted during rotation through the positioning component 5.

[0062] The mirror 6 is mounted on the adjustment plate 31 by the positioning component 5.

[0063] The first drive shaft 34 is driven and mounted on the bidirectional motor. The other end of the bidirectional motor is driven and connected to the second drive shaft 7. The second drive shaft 7 rotates synchronously with the first drive shaft 34. The rotation of the second drive shaft 7 drives the guide pipe 74 to deliver the coolant upward.

[0064] The housing 1 is also equipped with a milling assembly 9 for milling the mirror surface 6.

[0065] Furthermore, a cabinet door 11 is provided on the outside of the cabinet 1. An observation glass 12 is provided on the cabinet door 11 to facilitate the observation of the processing progress of the mirror 6. A baffle plate 13 is fixed on the inner wall of the bottom of the cabinet 1 facing the cabinet door 11 to prevent the coolant at the bottom of the cabinet 1 from flowing out. A water tank door 21 is also provided on the outside of the water tank 2. A flow channel 14 communicating with the water tank 2 is provided at the bottom of the cabinet 1. A collection channel 8 is provided below the flow channel 14. The collection channel 8 is a filter screen structure. The collection channel 8 is slidably installed on the top of the water tank 2 by a slide rail assembly.

[0066] The filter structure of the collection tank 8 filters and intercepts the debris from the mirror 6 processing, preventing it from entering the water tank 22. At the same time, the sliding installation structure of the collection tank 8 makes it easy to pull it out so that the filtered mirror 6 debris can be removed and reused.

[0067] Furthermore, a gap is left between the rotating assembly 3 and the adjusting disk 31 to allow the adjusting disk 31 to rotate. Rotating wheels 33 are rotatably mounted on the upper sides of both sides of the rotating assembly 3. A first telescopic rod 32 is mounted on the upper side of one of the rotating wheels 33, and the upper end of the first telescopic rod 32 is mounted on the inner wall of the adjusting disk 31. The upper side of the rotating wheel 33 on the other side is connected to the piston rod of the cylinder 36, and the cylinder 36 is also mounted on the inner wall of the adjusting disk 31.

[0068] The cylinder 36 controls the flipping direction of the adjusting plate 31. When the piston rod extends outward, the adjusting plate 31 rotates counterclockwise. When the piston rod retracts, the adjusting plate 31 rotates clockwise.

[0069] Furthermore, a movable groove is provided below the center of the adjusting disc 31, and a limiting wheel 4 is fixedly connected to the center of the movable groove. A first connecting block 35 is fixedly connected to the top of the first transmission shaft 34. The limiting wheel 4 is rotatably installed in the center of the first connecting block 35. A slot 41 is provided on the side wall of the limiting wheel 4. Several limiting blocks 42 are provided on the lower outer wall of the slot 41. The cross-section of the limiting block 42 is triangular. A locking post 43 is vertically slidably connected to the top of the first transmission shaft 34. The end of the locking post 43 is engaged between the right-angled sides of two adjacent limiting blocks 42.

[0070] Furthermore, a spring 44 is provided below the locking post 43. One end of the spring 44 is fixedly connected to the lower part of the locking post 43, and the other end of the spring 44 is fixedly connected to the inner wall of the first transmission shaft 34. A pull block 45 is fixedly connected to one side below the locking post 43. The pull block 45 extends out of the first transmission shaft 34 and is vertically slidably connected to the first transmission shaft 34.

[0071] The mirror 6 is rotated and flipped by the cylinder 36. During processing, the mirror 6 is flipped in one direction so that it can be milled from the outside to the inside. The locking structure between the limit block 42 and the locking post 43 makes the adjusting plate 31 only able to rotate in one direction. When it is necessary to reset, the pull block 45 is pulled down so that the locking post 43 retracts into the first drive shaft 34, which can reset the adjusting plate 31.

[0072] Furthermore, a positioning component 5 is fixedly connected to the upper axis of the adjusting disk 31. The positioning component 5 is configured as a hollow structure, and several evenly distributed bolts 51 are provided on the side wall of the positioning component 5.

[0073] One side of the mirror 6 is covered with a protective layer 61, and the other side of the protective layer 61 is formed into a metal base 62 by metal casting. A second connecting block 63 is fixedly connected to the bottom of the metal base 62. The side wall of the second connecting block 63 is provided with a plurality of positioning holes 64 corresponding to the bolt 51. The bolt 51 is threadedly connected to the positioning holes 64.

[0074] The metal base 62 and the second connecting block 63 are formed by hot-melting metal casting so as to fix the mirror 6 on the positioning component 5.

[0075] Furthermore, a first gear 71 is installed at the lower end of the second drive shaft 7, and a second gear 72 is provided on one side of the first gear 71 at the same horizontal plane. The first gear 71 and the second gear 72 mesh and drive each other. A worm gear 73 is fixedly installed on the shaft of the second gear 72. The worm gear 73 rotates in the guide pipe 74, driving the water flow in the guide pipe 74 to rise.

[0076] The relative rotation of the worm gear 73 within the guide tube 74 guides the coolant within the guide tube 74 upwards, thus achieving the recycling of the coolant.

[0077] Furthermore, the guide pipe 74 connects the housing 1 and the water tank 2. The guide pipe 74 is fixed at the connection between the housing 1 and the water tank 2. The lower end of the guide pipe 74 extends into the water tank 22, and there is a gap between the lower end of the guide pipe 74 and the upper part of the second gear 72. The upper end of the guide pipe 74 is connected to the upper water tank 75. Several water injection pipes 76 facing the milling position of the mirror surface 6 are installed on the upper water tank 75.

[0078] Coolant is injected into the milled part of the mirror surface 6 through the water injection pipe 76 to cool the milled part, prevent overheating that could damage the mirror surface 6 and the milling tool 91, increase the lubrication of the machining process, and wash away some of the debris.

[0079] Furthermore, an adjustment assembly 10 is installed on the top inner wall of the housing 1. The adjustment assembly 10 can move horizontally in multiple directions via a cross-shaped guide rail. The milling assembly 9 is fixedly installed below the adjustment assembly 10. The milling assembly 9 can move horizontally in any direction via the adjustment assembly 10. A rotatable and liftable milling cutter 91 is installed below the milling assembly 9.

[0080] The adjusting component 10 controls the milling component 9 to move arbitrarily in the horizontal direction, and the milling component 9 controls the rotation of the milling cutter 91 and its vertical movement, so that the surface of the mirror 6 can be milled at any angle and position.

[0081] The specific details of this plan are as follows:

[0082] A protective layer 61 is attached to one side of the mirror 6, and a metal seat 62 and a second connecting block 63 are formed by hot-melting metal onto the protective layer 61. The box 1 and water tank 2 are opened by opening the box door 11 and the water tank door 21. After inserting the second connecting block 63 into the positioning assembly 5, the bolt 51 is rotated so that the bolt 51 is screwed into the positioning hole 64 of the second connecting block 63, thereby fixing the mirror 6 onto the adjusting plate 31. After injecting coolant into the water tank 22, the box door 11 and the water tank door 21 are closed.

[0083] The bidirectional motor is started, causing the first drive shaft 34 to drive the rotating component 3 to rotate, that is, the mirror 6 rotates. The position of the milling component 9 is controlled by the adjusting component 10, and the milling cutter 91 is controlled to rotate and descend to mill the side of the mirror 6 where the non-protective layer 61 is attached.

[0084] During the processing, according to the aspherical requirements of the mirror surface 6, the piston rod of the cylinder 36 is controlled to extend and retract, causing the adjusting plate 31 to flip to one side, that is, tilting during the rotation of the mirror surface 6. While the limiting wheel 4 controls the adjustment plate 31 to flip, it prevents the adjustment plate 31 from rotating back, which would cause the processing position of the milling component 9 to deviate. The mirror surface 6 is milled from the outside to the center, and the height of the milling tool 91 is controlled by the milling component 9 to achieve the aspherical milling of the mirror surface 6.

[0085] During the milling process of mirror surface 6, the second drive shaft 7 at the other end of the bidirectional motor controls the rotation of the first gear 71, and due to its meshing transmission with the second gear 72, it drives the worm gear 73 to rotate in the guide pipe 74, which guides the water in the water tank 22 upward into the upper water tank 75, and injects coolant into the milling position of mirror surface 6 through the water injection pipe 76 to cool and lubricate the mirror surface 6 and the milling tool 91 for protection.

[0086] Meanwhile, the mirror 6 debris and coolant generated during processing enter the bottom of the tank 1 and are blocked by the baffle 13 to prevent them from flowing out. The coolant and debris pass through the flow channel 14 and enter the water tank 22 of the water tank 2. The debris will enter the collection tank 8 for filtration and collection, so that the coolant can be recycled and the mirror 6 debris will be avoided from being carried into the circulation.

[0087] After the mirror 6 is processed, open the water tank 2 and the box 1, take out the mirror 6, and pull out the collection tank 8. Recycle the collected mirror 6 debris and process the next mirror 6. If you stop using it, you can drain the coolant from the water tank 22.

[0088] This invention is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.

10. A milling method for optical aspherical mirrors, comprising the milling apparatus for optical aspherical mirrors as described in any one of claims 1-9, characterized in that, Includes the following steps: S1: Attach a protective layer (61) to one side of the mirror (6), and form a metal base (62) and a connecting block (63) by hot-melting metal casting on the protective layer (61). Open the box (1) and water tank (2) through the box opening door (11) and water tank opening door (21), insert the connecting block (63) into the positioning component (5), and rotate the bolt (51) so that the bolt (51) is screwed into the positioning hole (64) of the connecting block (63) to fix the mirror (6) on the adjustment plate (31). After injecting coolant into the water tank (22), close the box opening door (11) and water tank opening door (21). S2: Start the bidirectional motor so that the first drive shaft (34) drives the rotating component (3) to rotate, that is, the mirror (6) rotates. The position of the milling component (9) is controlled by the adjusting component (10), and the milling cutter (91) is controlled to rotate and descend to mill the side of the mirror (6) where the non-protective layer (61) is attached. S3: During the processing, according to the aspherical requirements of the mirror (6), the piston rod of the cylinder (36) is controlled to extend and retract, so that the adjustment plate (31) is flipped to one side, that is, the mirror (6) is tilted during the rotation. The limit wheel (4) controls the adjustment plate (31) to flip while avoiding the adjustment plate (31) from rotating back, which would cause the processing position of the milling assembly (9) to deviate. The mirror (6) is milled from the outside to the center, and the height of the milling tool (91) is controlled by the milling assembly (9) to realize the aspherical milling of the mirror (6). S4: During the milling process of the mirror surface (6), the second drive shaft (7) at the other end of the bidirectional motor controls the first gear (71) to rotate. Due to its meshing transmission with the second gear (72), it drives the worm (73) to rotate in the guide pipe (74), which guides the water in the water tank (22) upward into the upper water tank (75). The coolant is injected into the milling position of the mirror surface (6) through the water injection pipe (76) to cool and lubricate the mirror surface (6) and the milling tool (91). S5: Simultaneously, the mirror (6) debris and coolant generated during processing enter the bottom of the box (1) and are blocked by the baffle (13) to prevent them from flowing out. The coolant and debris pass through the flow channel (14) and enter the water tank (22) of the water tank (2). The debris will enter the collection tank (8) for filtration and collection, so that the coolant can be recycled and the mirror (6) debris is prevented from being carried into the circulation. S6: After the mirror (6) is processed, open the water tank (2) and the box (1), take out the mirror (6), and pull out the collection tank (8). Recycle the collected mirror (6) debris and process the next mirror (6). If you stop using it, you can drain the coolant from the water tank (22).
