Description

Technical Field

[0001] This utility model relates to the field of optical cylindrical mirror processing technology, and specifically to a positioning device for optical cylindrical mirror processing. Background Technology

[0002] Polishing is an essential step in the processing of optical lenses. Polishing reduces the roughness of the workpiece surface to obtain a bright and smooth surface, which leads to the use of positioning polishing equipment for optical lens processing.

[0003] Currently, to facilitate the polishing of cylindrical mirrors, most optical cylindrical mirror grinding machines are equipped with clamping mechanisms on their processing tables. When polishing cylindrical mirrors, the clamping mechanisms are used to hold and fix the cylindrical mirrors, thereby improving the stability of the polishing process.

[0004] However, most existing clamping mechanisms can only polish the top surface of a cylindrical mirror when clamping it. Since polishing a cylindrical mirror often requires polishing its outer walls to prevent burrs or rough surfaces that could cause edge scattering, the above-mentioned clamping mechanisms require frequent unclamping and manual adjustment of the mirror angle before the entire outer wall can be polished. This process is cumbersome, time-consuming, and labor-intensive, reducing the polishing efficiency of optical cylindrical mirrors. Utility Model Content

Sliding plates are horizontally slidably mounted on the mounting plate and within the two sliding joints. The two sliding plates are fixedly connected to the two connecting posts respectively. The tops of the two connecting posts extend above the first disc. Clamping plates are fixedly mounted on the side of the two connecting posts that are close to each other and above the first disc. A driving component connected to both sliding plates is mounted on the mounting plate, which is used to make the two sliding plates slide in opposite directions or stop sliding within the two sliding joints respectively.

[0012] Furthermore: each of the two clamping plates has a clamping groove with a V-shaped cross-section on one side that is close to each other. A rubber pad is fixedly installed on the clamping plate and in the clamping groove. The driving component includes a bidirectional threaded rod that is horizontally rotatably installed on one side of the mounting plate.

[0013] Furthermore: the adjusting component includes a threaded rod 1 that is horizontally rotatably mounted on the vertical plate, the threaded rod 1 being threadedly connected to the slider, and one end of the threaded rod 1 extending to the outside of the vertical plate and being coaxially fixed to a knob 2.

Two extension plates with opposite directions of movement are slidably installed on the fixing block and inside the cavity. The ends of the two extension plates that are far apart from each other extend to the outside of the fixing block. Positioning holes are symmetrically formed at the ends of the extension plates that extend to the outside of the fixing block.

[0016] This invention provides a positioning device for processing optical cylindrical mirrors. Compared with the prior art, it has the following advantages:

[0017] 1. This method replaces the existing method of frequently canceling the clamping mechanism on the cylindrical mirror body, and then manually adjusting the angle of the cylindrical mirror body and re-clamping it to gradually complete the polishing process of the entire outer wall. It is simple to operate, saves time and effort, and thus improves the polishing efficiency of optical cylindrical mirrors.

[0018] 2. Utilizing the clamping groove design, when the two clamping plates clamp and position the cylindrical mirror body, the outer wall of the cylindrical mirror body is located on the inner wall of the clamping groove, increasing the contact surface between the clamping plates and the cylindrical mirror body, thereby enhancing the positioning effect of the cylindrical mirror body. Through the design of the rubber pad, the two clamping plates and the cylindrical mirror body make flexible contact, effectively avoiding wear on the outer wall of the cylindrical mirror body, while increasing the friction between the clamping plates and the cylindrical mirror body, thus enhancing the positioning effect of the cylindrical mirror body.

[0019] 3. Utilizing the design of the fixed base, which includes a fixed block and extension plates, the two extension plates can be slid in opposite directions along the cavity through the adjustment mechanism during use. This allows for adjustment of the distance between the two extension plates, thereby adjusting the total length of the fixed base. This enables the distance between the two extension plates to be adjusted according to different models of optical cylindrical mirror grinding machines, allowing the equipment to be fixed on the processing table of the optical cylindrical mirror grinding machine, thus improving the applicability of the equipment.

[0030] Example

[0031] To address the technical problems in the background art, the following positioning device for processing optical cylindrical mirrors is provided:

[0032] Combination Figures 1-7 As shown, the positioning device for processing optical cylindrical mirrors provided by this utility model includes a fixed base 1 for mounting on the processing table of an optical cylindrical mirror grinding machine. A vertical plate 2 is fixedly installed on the top of the fixed base 1. An arc groove 21 is opened at one end of the plate 2. A connecting shaft 22 is slidably hinged on the plate 2 and located in the arc groove 21. An mounting plate 3 that fits against the plate 2 is fixed at one end of the connecting shaft 22. A driving component 23 connected to the connecting shaft 22 is installed on the plate 2. It is used to make the connecting shaft 22 slide along the arc groove 21. When the connecting shaft 22 is at the lowest end of the arc groove 21, the mounting plate 3 rotates around the connecting shaft 22 to be horizontal. When the connecting shaft 22 is at the highest end of the arc groove 21, the mounting plate 3 rotates around the connecting shaft 22 to be vertical.

[0033] A vertically oriented rotating shaft 31 is rotatably mounted on the mounting plate 3. A disc 32 is coaxially fixed to the top of the rotating shaft 31. A motor 33 for driving the rotating shaft 31 to rotate is fixedly mounted on the bottom of the mounting plate 3. A cylindrical mirror body 34 is placed on the top of the disc 32. A positioning member 4 for the cylindrical mirror body 34 is mounted on the mounting plate 3 and located outside the disc 32. The positioning member 4 is used to position the cylindrical mirror body 34 placed on the top of the disc 32 so that the cylindrical mirror body 34 is located at the center of the top of the disc 32.

[0034] A horizontal groove 24 is provided on the upright plate 2 along the direction of the connecting shaft 22. A slider 25 is horizontally slidably installed on the upright plate 2 within the groove 24. A movable plate 5 is fixedly installed on the slider 25 on the side of the upright plate 2 near the mounting plate 3, and is in contact with the upright plate 2. A horizontal rotating shaft 51 is rotatably installed on the movable plate 5. A disc 52 is coaxially fixed to the end of the rotating shaft 51 near the mounting plate 3. An adjusting member 26 connected to the slider 25 is installed on the upright plate 2. It is used to make the slider 25 slide closer to or away from the mounting plate 3 within the groove 24. When the mounting plate 3 rotates around the connecting shaft 22 to a vertical position, the disc 52 and the disc 32 are located on the same axial direction.

[0035] In use, when polishing the end face of the cylindrical mirror body 34, the cylindrical mirror body 34 is placed on the disk 32. The positioning member 4 clamps and positions the outer wall of the cylindrical mirror body 34, which is placed on top of the disk 32, so that the cylindrical mirror body 34 is located at the center of the top of the disk 32. At this time, the optical cylindrical mirror grinding machine can be controlled to operate, so that the polishing wheel of the optical cylindrical mirror grinding machine contacts the end face of the cylindrical mirror body 34, thereby polishing the end face of the cylindrical mirror body 34. When polishing is required on the outer wall of the cylindrical mirror body 34, the operator controls the drive component 23 to slide the connecting shaft 22 along the arc groove 21. When the connecting shaft 22 is at the highest point of the arc groove 21, the mounting plate 3 rotates around the connecting shaft 22 to a vertical position, thereby making the cylindrical mirror body 34 horizontal and positioning it on the side of the first disk 32 closer to the second disk 52. At this time, the operator uses the adjustment component 26 to slide the slider 25 in the groove 24 towards the first disk 32. The movement is achieved by moving the plate 5 to slide the second disk 52 towards the cylindrical mirror body 34, causing the second disk 52 to abut against the end face of the cylindrical mirror body 34. At this time, the positioning of the cylindrical mirror body 34 by the positioning component 4 is canceled, and the first disk 32 and the second disk 52 clamp and position the cylindrical mirror body 34. The control motor 33 is turned on, and the first disk 32 is rotated through the rotating shaft 31, thereby rotating the cylindrical mirror body 34. At this time, the optical cylindrical mirror grinding machine can be controlled to operate, so that the polishing wheel of the optical cylindrical mirror grinding machine contacts the outer wall of the cylindrical mirror body 34. By controlling the horizontal displacement of the polishing wheel of the optical cylindrical mirror grinding machine, the outer wall of the cylindrical mirror body 34 can be completely polished. This replaces the existing method of frequently canceling the clamping mechanism on the cylindrical mirror body 34, and then manually adjusting the angle of the cylindrical mirror body 34 and re-clamping it to gradually complete the polishing of the entire outer wall. The operation is simple, time-saving and labor-saving, thereby improving the polishing efficiency of the optical cylindrical mirror.

[0036] Combination Figures 1-7 As shown, the driving component 23 includes a bracket 231 fixedly mounted on the upright plate 2 and on the side away from the mounting plate 3. A horizontally oriented rotating shaft 232 is rotatably mounted on the bracket 231. The center of the arc-shaped groove 21 is located in the axial direction of the rotating shaft 232. A rotating plate 233 that fits against the upright plate 2 is coaxially fixed to the end of the rotating shaft 232. The other end of the connecting shaft 22 is fixedly connected to the eccentric part of the rotating plate 233. A motor 234 for driving the rotating shaft 232 to rotate is fixedly mounted on the bracket 231. In use, the motor 234 is turned on, and the rotating plate 233 is driven to rotate around the rotating shaft 232 through the rotating shaft 232. The connecting shaft 22 rotates around the rotating plate 233, thereby driving the connecting shaft 22 to slide along the arc-shaped groove 21 in the arc-shaped groove 21, so that the connecting shaft 22 is displaced to the highest or lowest end of the arc-shaped groove 21 for easy control.

[0037] Combination Figures 1-7 As shown, the positioning component 4 includes a sliding plate 41, a connecting post 42, a clamping plate 43, and a driving component 44. The top of the mounting plate 3, located on both sides of the disc 32, has sliding grooves 35. One side of the mounting plate 3 has two sliding grooves 36 that communicate with the two sliding grooves 35 respectively. Connecting posts 42 are slidably mounted on the mounting plate 3 within the two sliding grooves 35 along the direction of the disc 32. Sliding plates 41 are horizontally slidably mounted on the mounting plate 3 within the two sliding grooves 36. Two sliding plates 41 are fixedly connected to two connecting posts 42 respectively. The tops of both connecting posts 42 extend above the first disk 32. Clamping plates 43 are fixedly installed on the side of the two connecting posts 42 that are close to each other and above the first disk 32. A driving member 44 connected to both sliding plates 41 is installed on the mounting plate 3. This driving member 44 is used to make the two sliding plates 41 slide in opposite directions or stop sliding in the two sliding grooves 36 respectively. In use, when positioning the cylindrical mirror body 34, the cylindrical mirror body 34 is placed on the top of the first disk 32 and between the opposite sides of the two clamping plates 43. The driving member 44 makes the two sliding plates 41 slide in opposite directions and move closer to each other in the two sliding grooves 36 respectively. Thus, the two sliding plates 41 drive the two connecting posts 42 to slide in opposite directions and move closer to each other in the two sliding grooves 35 respectively. This drives the two clamping plates 43 to move closer to each other, so that the two clamping plates 43 abut against the cylindrical mirror body 34. Thus, the cylindrical mirror body 34 is positioned on the top of the first disk 32. At the center, when grinding the outer wall of the cylindrical mirror body 34, the mounting plate 3 is rotated around the connecting shaft 22 to a vertical position, and the moving plate 5 slides along the slider 25 toward the mounting plate 3, so that the second disk 52 abuts against the cylindrical mirror body 34 and positions the cylindrical mirror body 34. Then, the driving member 44 causes the two sliding plates 41 to slide in opposite directions and move away from each other in the two sliding grooves 36, so that the two clamping plates 43 are both located outside the first disk 32, thus achieving the effect of making way for the cylindrical mirror body 34.

[0038] Combination Figures 1-7As shown, each of the two clamping plates 43 has a V-shaped clamping groove on one side of each other. A rubber pad 431 is fixedly installed on the clamping plate 43 within the clamping groove. Utilizing the design of the clamping groove, when the two clamping plates 43 clamp and position the cylindrical mirror body 34, the outer wall of the cylindrical mirror body 34 is located within the inner wall of the clamping groove, increasing the contact area between the clamping plates 43 and the cylindrical mirror body 34, thus enhancing the positioning effect of the cylindrical mirror body 34. The design of the rubber pad 431 allows for flexible contact between the two clamping plates 43 and the cylindrical mirror body 34, effectively preventing wear on the outer wall of the cylindrical mirror body 34. Simultaneously, it increases the friction between the clamping plates 43 and the cylindrical mirror body 34, increasing the protection of the cylindrical mirror body. The positioning effect of body 34 is achieved by the driving component 44, which includes a bidirectional threaded rod 441 that is horizontally rotatably mounted on one side of the mounting plate 3. The ends of the two sliding plates 41 extend to the outside of the mounting plate 3, and the two sliding plates 41 are threadedly connected to the bidirectional threaded rod 441. One end of the bidirectional threaded rod 441 is integrally formed with a knob. In use, the operator rotates the bidirectional threaded rod 441 on the mounting plate 3 by turning the knob, thereby allowing the two sliding plates 41 to slide in opposite directions in the two sliding grooves 36 respectively. The operation is simple. Since the two sliding plates 41 are threadedly connected to the bidirectional threaded rod 441 and have self-locking properties, the positions of the two sliding plates 41 can be fixed without rotating the bidirectional threaded rod 441 by turning the knob.

[0039] Combination Figures 1-7 As shown, the adjusting component 26 includes a threaded rod 261 that is horizontally rotatably mounted on the vertical plate 2. The threaded rod 261 is threadedly connected to the slider 25. One end of the threaded rod 261 extends to the outside of the vertical plate 2 and is coaxially fixed to a knob. In use, the operator rotates the threaded rod 261 on the vertical plate 2 by turning the knob, thereby driving the slider 25 to slide along the slide groove 24. The operation is simple.

[0040] Combination Figures 1-7As shown, the fixing base 1 includes a fixing block 11 and extension plates 12. A cavity 111 is formed inside the fixing block 11. Two extension plates 12 with opposite directions of movement are slidably mounted on the fixing block 11 and within the cavity 111. Specifically, the outer walls of the extension plates 12 are in contact with the inner walls of the cavity 111. The ends of the two extension plates 12 that are far apart from each other extend to the outside of the fixing block 11. Symmetrical positioning holes 121 are formed at the ends of the extension plates 12 that extend to the outside of the fixing block 11. The design of the positioning holes 121 facilitates fixing the two extension plates 12 onto the processing table of the optical cylindrical mirror grinding machine. The fixing block 11 is equipped with extension plates 121 that extend into the cavity 111 and are located within the cavity 111. The adjustment mechanism 6 on the opposite side of the extension plate 12 is connected to both extension plates 12. The adjustment mechanism 6 is used to make the two extension plates 12 slide in opposite directions or stop sliding along the cavity 111. Utilizing the design of the fixed base 1, which includes a fixed block 11 and extension plates 12, the two extension plates 12 can be made to slide in opposite directions along the cavity 111 by adjusting the adjustment mechanism 6 during use. This allows the distance between the two extension plates 12 to be adjusted, thereby adjusting the total length of the fixed base 1. This allows the distance between the two extension plates 12 to be adjusted according to different models of optical cylindrical mirror grinding machines, so that the equipment can be fixed on the processing table of the optical cylindrical mirror grinding machine, improving the applicability of the equipment.

[0041] Combination Figures 1-7 As shown, the adjustment mechanism 6 includes a guide rod 61, a sliding block 62, a hinge rod 63, and a threaded rod 64. Horizontally fixed guide rods 61 are symmetrically installed within the cavity 111 on opposite sides of the two extension plates 12. Specifically, the axial direction of the guide rods 61 is perpendicular to the sliding direction of the extension plates 12 along the cavity 111. Sliding blocks 62 are slidably installed on the two guide rods 61 along their axial direction. Hinged rods 63 are hinged to both sides of each sliding block 62. The other ends of the two hinged rods 63 are respectively hinged to the two extension plates 12. A horizontally fixed threaded rod 64 is rotatably installed on the fixed block 11. One end of the threaded rod 64 extends into the cavity 111 and is threadedly connected to the sliding block 62; the other end extends to the outside of the fixed block 11 and is coaxial. A knob three is fixedly connected. When adjusting the distance between the two extension plates 12, the screw rod 64 is rotated on the fixed block 11 by the knob three, which causes the sliding block 62 to slide along the two guide rods 61. At this time, the two hinge rods 63 rotate around their own hinge points on both sides of the sliding block 62. The other ends of the two hinge rods 63 rotate between the two extension plates 12, causing the two extension plates 12 to slide in opposite directions and move away from or closer to each other in the cavity 111. The operation is simple. Since the threaded connection between the screw rod 64 and the sliding block 62 has self-locking properties, the sliding block 62 will not slide along the two guide rods 61 when the screw rod 64 is not rotated by the knob three. Thus, the position of the sliding block 62 and the position of the two extension plates 12 can be fixed, which is convenient for use.

[0042] Working principle and usage process of this utility model:

[0043] The first step is for the operator to rotate the threaded rod 64 on the fixed block 11 by turning the knob three, so that the sliding block 62 slides along the two guide rods 61, and the two extension plates 12 slide in opposite directions in the cavity 111, moving away from or closer to each other. The distance between the two extension plates 12 is adjusted according to the different models of optical cylindrical mirror grinding machines. Then, the two extension plates 12 are fixed on the processing table of the optical cylindrical mirror grinding machine through the positioning holes 121 on the two extension plates 12, thus completing the installation of this equipment.

[0044] In the second step, when polishing the end face of the cylindrical mirror body 34, the control motor 234 is turned on, and the rotating plate 233 is driven to rotate around the rotating shaft 232 via the rotating shaft 232. This causes the connecting shaft 22 to slide along the arc groove 21, so that the connecting shaft 22 is moved to the lowest end of the arc groove 21. The mounting plate 3 rotates around the connecting shaft 22 to a horizontal position, placing the cylindrical mirror body 34 on top of the disc 32 and between the two clamping plates 43 on opposite sides. The operator turns the knob 1 to enable bidirectional rotation. The threaded rod 441 rotates on the mounting plate 3, causing the two sliding plates 41 to slide in opposite directions and approach each other in the two sliding grooves 36, which in turn drives the two clamping plates 43 to approach each other, so that both clamping plates 43 abut against the cylindrical mirror body 34, and the cylindrical mirror body 34 is located at the center of the top of the disk 32. At this time, the optical cylindrical mirror grinding machine can be controlled to operate, so that the polishing wheel of the optical cylindrical mirror grinding machine contacts the end face of the cylindrical mirror body 34, thereby polishing the end face of the cylindrical mirror body 34.

[0045] In the third step, when polishing the outer wall of the cylindrical mirror body 34, the control motor 234 is turned on, and the rotating plate 233 is driven to rotate around the rotating shaft 232, causing the connecting shaft 22 to slide along the arc groove 21, so that the connecting shaft 22 is moved to the highest end of the arc groove 21. The mounting plate 3 rotates around the connecting shaft 22 to a vertical position, so that the cylindrical mirror body 34 is horizontal, and the cylindrical mirror body 34 is located on the side of the disk 32 close to the disk 52. At this time, the operator rotates the threaded rod 261 on the upright plate 2 by turning the knob 2, which drives the slider 25 to slide along the groove 24. The sliding displacement causes the second disk 52 to contact the end face of the cylindrical mirror body 34 and position the cylindrical mirror body 34. Then, the operator rotates the bidirectional threaded rod 441 on the mounting plate 3 by turning the first knob, so that the two sliding plates 41 slide in opposite directions and move away from each other in the two sliding grooves 36 respectively. This makes the two clamping plates 43 located outside the first disk 32, giving way to the cylindrical mirror body 34. The operator controls the operation of the optical cylindrical mirror grinding machine, so that the polishing wheel of the optical cylindrical mirror grinding machine contacts the outer wall of the cylindrical mirror body 34. Then, by controlling the horizontal displacement of the polishing wheel of the optical cylindrical mirror grinding machine, the outer wall of the cylindrical mirror body 34 can be completely polished.
