Description

Technical Field

[0001] This utility model belongs to the field of prism lens processing technology, and in particular relates to a flip-up fixing frame for prism lens processing. Background Technology

[0002] A prism is a transparent object formed by two intersecting but non-parallel planes used to split light or cause light beams to disperse. Prisms are polyhedrons made of transparent material and are widely used in optical instruments. Prisms can be classified into several types according to their properties and uses. In spectroscopic instruments, a "dispersive prism" is used to decompose composite light into a spectrum.

[0003] When processing prism lenses, a fixing frame is usually used to hold the lens in place, which facilitates the operation of the lens by the workers. After processing one side of the lens, the other side of the lens needs to be processed in the same way. This requires removing the lens from the fixing frame, changing it to the other side, and then placing it back on the fixing frame to fix it again. This operation not only consumes time and reduces work efficiency, but also the lens may be deviated from its original fixing position when it is put back in, resulting in different flatness on the two sides of the lens, thus affecting the quality of the finished prism lens. Therefore, we propose a flip-up fixing frame for processing prism lenses. Utility Model Content

[0004] The purpose of this invention is to provide a flip-up fixture for processing prism lenses. By setting a flip-up component, after processing one side of the lens, it can be easily flipped to process the other side without manually removing and repositioning the lens, saving time and avoiding the need to re-fix and readjust the position of the lens. This solves the problem that after processing one side of the lens, the other side needs to be processed in the same way, which requires removing the lens from the fixture, changing it to the other side, and then placing it back on the fixture for re-fixing. The repositioned lens may deviate from its original fixed position, resulting in different flatness on the two sides of the lens, thus affecting the quality of the finished prism lens.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a rotatable fixing frame for processing prism lenses, including a turntable, a support leg provided below the turntable, a support frame fixedly connected to the inner wall of the support leg, a motor fixedly connected to the end of the support frame away from the turntable, a rotating shaft fixedly connected to the output end of the motor, the outer surface of the rotating shaft being rotatably connected to the inner wall of the support frame, and the end of the rotating shaft away from the motor being fixedly connected to the bottom of the turntable.

[0007] The turntable is internally equipped with a flipping assembly, which includes an adjusting plate. The bottom of the adjusting plate has two limiting grooves, which are symmetrically arranged. Each limiting groove has a limiting block at its bottom. A connecting frame is fixedly connected to the side of each limiting block that is close to the limiting block. The end of each connecting frame that is away from the limiting block is fixedly connected to the bottom of the adjusting plate. The outer surface of the adjusting plate is equipped with two flipping blocks. Each flipping block has two rotating rollers rotatably connected to the side of the adjusting plate that is close to the adjusting plate. As the rollers slide on the inner wall of the limiting groove, the flipping blocks flip. After processing one side of the lens, the lens can be easily flipped to process the other side without manually removing and repositioning the lens.

[0008] Furthermore, the support frame has an annular groove inside, and a limiting ring is rotatably connected to the inner wall of the annular groove. The inner wall of the limiting ring is fixedly connected to the outer surface of the rotating shaft, and the outer surface of the rotating shaft is rotatably connected to the center of the adjusting plate. The top of the support frame is fixedly connected to the bottom of the adjusting plate. By setting the limiting ring, the rotating shaft can remain stable and will not deviate while rotating inside the support frame.

[0009] Furthermore, the outer surfaces of the four rollers are in contact with the bottom of the adjusting disk, and the two rotating blocks are fixedly connected to a connecting shaft on the side away from each other. The ends of the two connecting shafts away from the rotating blocks penetrate the side wall of the turntable and extend to the outside. The extensions of the two rotating blocks are fixedly connected to a support plate, and the rotating blocks drive the support plate to rotate through the connecting shaft.

[0010] Furthermore, both of the support plates are provided with fixing components on their outer surfaces. The side walls of the support plates have two square grooves. The fixing components include slide rods fixedly connected to the inner walls of the square grooves. The outer surfaces of the two slide rods are slidably connected to two clamping plates, and the slide rods provide a stable movement trajectory for the clamping plates.

[0011] Furthermore, each of the two clamping plates has an arc-shaped groove on one side that is close to each other, and the inner wall of each of the two arc-shaped grooves is rotatably connected to a roller. The lens is placed between the two clamping plates, and the side walls of the two clamping plates are provided with rollers. The rollers facilitate the placement of the lens between the two clamping plates, and the arc-shaped grooves can prevent the lens from falling off after it is fixed.

[0012] Furthermore, two springs are fitted on the outer surface of the upper sliding rod. The ends of the two springs that are close to each other are fixedly connected to the side wall of the clamping plate, and the ends of the two springs that are away from the clamping plate are fixedly connected to the inner wall of the square groove. The elastic force generated by the springs pushes the clamping plate closer to the lens, and the clamping plates on both sides apply pressure to the lens, thereby fixing the lens inside the arc groove. When the lens is processed and polished, the positional stability of the lens can be ensured during the processing, and the lens can be prevented from moving or deflecting during processing.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model features a flipping component. Specifically, a roller slides along the bottom of the adjusting plate with the flipping block. When the roller moves to the position of the limiting groove, it slides according to the shape of the limiting groove. As the roller slides along the inner wall of the limiting groove, the flipping block flips. The flipping block then drives the support plate to flip via the connecting shaft. While the support plate flips, it also drives the lens fixed between the two clamping plates to flip. After processing one side of the lens, the lens can be easily flipped to process the other side without manually removing and repositioning the lens, saving time and avoiding the need to re-reinforce the lens and then correct its position.

[0015] 2. This utility model, through the setting of a fixing component, specifically, as the lens is placed in, the clamps on both sides move away from each other. At the same time, the clamps on both sides compress the springs on both sides. The springs are compressed and generate opposite elastic forces. When the lens is placed into the arc-shaped groove opened in the side wall of the clamp, the elastic force generated by the spring pushes the clamp closer to the lens. The clamps on both sides then apply pressure to the lens, thereby fixing the lens inside the arc-shaped groove. During lens processing and polishing, it can ensure the positional stability of the lens during the processing, prevent the lens from moving or deflecting during processing, and thus ensure the accuracy of the lens processing results.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-5 As shown, this utility model is a rotatable fixing frame for processing prism lenses, including a turntable 1, a support leg 101 is provided below the turntable 1, a support frame 102 is fixedly connected to the inner wall of the support leg 101, a motor 103 is fixedly connected to the end of the support frame 102 away from the turntable 1, a rotating shaft 104 is fixedly connected to the output end of the motor 103, the outer surface of the rotating shaft 104 is rotatably connected to the inner wall of the support frame 102, and the end of the rotating shaft 104 away from the motor 103 is fixedly connected to the bottom of the turntable 1;

[0027] The turntable 1 is internally equipped with a flipping assembly 2, which includes an adjusting plate 201. The bottom of the adjusting plate 201 has two symmetrically arranged limiting grooves 202. Each limiting groove 202 has a limiting block 203 at its bottom. A connecting frame 204 is fixedly connected to the side of each limiting block 203 closest to it. The ends of each connecting frame 204 away from the limiting blocks 203 are fixedly connected to the bottom of the adjusting plate 201. The outer surface of the adjusting plate 201 has two flipping blocks 205. Two circular rollers 206 are rotatably connected to the side of each flipping block 205 closest to the adjusting plate 201. By setting up the flipping assembly 2, specifically... Roller 206 slides along the bottom of adjustment plate 201 with flipping block 205. When roller 206 moves to the position of limiting groove 202, roller 206 slides with the shape of limiting groove 202. As roller 206 slides on the inner wall of limiting groove 202, flipping block 205 flips. Flipping block 205 then drives support plate 303 to flip through connecting shaft 302. Support plate 303 flips while driving lens fixed between two clamping plates 401. After processing one side of lens, lens can be easily flipped to process the other side without manually removing and repositioning lens, saving time and avoiding the need to re-reinforce and correct the position of lens.

[0028] The rotating support frame 102 has an annular groove inside. The inner wall of the annular groove is rotatably connected to a limiting ring 301. The inner wall of the limiting ring 301 is fixedly connected to the outer surface of the rotating shaft 104. The outer surface of the rotating shaft 104 is rotatably connected to the center of the adjusting plate 201. The top of the support frame 102 is fixedly connected to the bottom of the adjusting plate 201.

[0029] The outer surfaces of the four rollers 206 are in contact with the bottom of the adjusting disc 201, and the two flipping blocks 205 are fixedly connected to the connecting shafts 302 on the opposite sides.

[0030] The ends of the two connecting shafts 302 away from the flipping block 205 both penetrate the side wall of the turntable 1 and extend to the outside. The extensions of the two flipping blocks 205 are fixedly connected to the support plate 303.

[0031] Both support plates 303 have a fixing component 4 on their outer surface. The side wall of the support plate 303 has two square grooves 304. The fixing component 4 includes a slide rod 404 fixedly connected to the inner wall of the square groove 304. The outer surfaces of the two slide rods 404 are slidably connected to two clamping plates 401.

[0032] Both clamping plates 401 have arc-shaped grooves 402 on their sides that are close to each other, and rollers 403 are rotatably connected to the inner walls of both arc-shaped grooves 402.

[0033] Two springs 405 are fitted on the outer surface of the upper slide bar 404. The ends of the two springs 405 that are close to each other are fixedly connected to the side wall of the clamping plate 401, and the ends of the two springs 405 that are away from the clamping plate 401 are fixedly connected to the inner wall of the square groove 304. By setting the fixing component 4, specifically, as the lens is placed in, the clamping plates 401 on both sides move away from each other. At the same time, the clamping plates 401 on both sides compress the springs 405 on both sides. The springs 405 generate opposite elastic forces when they are compressed. When the lens is placed into the arc-shaped groove 402 opened in the side wall of the clamping plate 401, the elastic force generated by the springs 405 pushes the clamping plate 401 closer to the lens. The clamping plates 401 on both sides thus apply pressure to the lens, thereby fixing the lens inside the arc-shaped groove 402. When the lens is processed and polished, the positional stability of the lens can be ensured during the processing, preventing the lens from moving or deflecting during processing, thereby ensuring the accuracy of the lens processing results.

[0034] A specific application of this embodiment is as follows: The support leg 101 is placed on a flat workbench, and the lens is inserted between the two clamping plates 401. The side walls of the clamping plates 401 are provided with rollers 403, which facilitate the placement of the lens between the two clamping plates 401. As the lens is inserted, the two clamping plates 401 move away from each other. At the same time, the two clamping plates 401 compress the springs 405 on both sides. The springs 405 generate opposite elastic forces when compressed. When the lens is inserted into the arc-shaped groove 402 opened in the side wall of the clamping plate 401, the elastic force generated by the springs 405 pushes the clamping plate 401 closer to the lens. The clamping plates 401 on both sides thus apply pressure to the lens, thereby fixing the lens inside the arc-shaped groove 402. When processing and polishing the lens, the positional stability of the lens can be ensured during the processing, preventing the lens from moving or deflecting during processing, thereby ensuring the accuracy of the lens processing results. Another lens can be fixed to the other side of the device in this way.

[0035] After the two lenses are clamped and fixed, the worker begins processing one side of the lens. When processing the other side of the lens is required, the motor 103 is started, driving the rotating shaft 104 to rotate clockwise. As the rotating shaft 104 rotates, it drives the top turntable 1 to rotate. The turntable 1 drives the flipping block 205 to slide on the outer surface of the adjusting plate 201 via the connecting shaft 302. The side wall of the flipping block 205 is provided with a roller 206. The roller 206 slides along the bottom of the adjusting plate 201 with the flipping block 205. When the roller 206 moves to the position of the limiting groove 202, the limiting block 203 restricts the roller 206 at the limiting groove 202. The roller 206 slides along the shape of the limiting groove 202 as the roller 206 slides on the inner wall of the limiting groove 202. As the roller 206 slides on the inner wall of the limiting groove 202, the flipping block 205 flips. The flipping block 205 then drives the support plate 303 to flip through the connecting shaft 302. While the support plate 303 is flipping, it also drives the lens fixed between the two clamping plates 401 to flip. This design allows the lens to be easily flipped to process the other side after one side of the lens has been processed. There is no need to manually remove and reposition the lens, thus avoiding the need to re-reinforce the lens and then correct its position, thereby saving time. At this time, the worker processes the other side of the lens.
