Description

Technical Field

[0001] The utility model belongs to the technical field of processing plano-convex lenses, and particularly relates to a clamping device for processing plano-convex lenses. Background Art

[0002] A plano-convex lens is a common type of lens in an optical system. Its main feature is having one flat surface and one convex surface, thus getting its name. The two surfaces of the plano-convex lens work together to focus parallel light rays to the positive focal point. Specifically, when parallel light rays enter from the convex surface, through the refraction of the lens, the light rays converge on the other side of the lens, forming a bright and clear focal point. At the same time, since the flat part of the plano-convex lens has no focusing or defocusing effect on light rays, it will not introduce additional aberrations.

[0003] In the prior art, there is a clamping device for processing plano-convex lenses or plano-concave lenses with the patent publication number CN210189323U. When the above patent is used, positioning is carried out simultaneously from the edge and the spherical surface of the lens through a stop block and a part seat, so that the mechanical center of the lens and the axis of the part seat are on the same vertical line. With such a setting, after the flat surface of the lens is processed, there is no need to correct the center deviation of the lens, eliminating the edge-cutting process and avoiding problems such as material waste, cracking, and scratching of the formed surface caused by edge-cutting. However, there are still the following deficiencies in actual use: In practice, when this clamping device clamps a plano-convex lens, it is necessary to manually rotate a nut or a bolt according to the size of the plano-convex lens to clamp the lens. When manually clamping, the magnitude of the clamping force often depends on the experience and feel of the operator, which makes it difficult to precisely control the clamping force, and increases the labor intensity of the operator. Long-term work may cause the operator to be fatigued, thereby affecting work efficiency and processing quality.

[0004] Therefore, a clamping device for processing plano-convex lenses is needed to solve the problem in the prior art that it is necessary to manually rotate a nut or a bolt to clamp the lens, resulting in difficult precise control of the clamping force. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a clamping device for processing plano-convex lenses to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A clamping device for processing plano-convex lenses, comprising a base, mounting holes, mounting posts, a clamping mechanism, support posts, and a plano-convex lens. The base is evenly provided with mounting holes, the mounting posts are arranged inside the mounting holes, the clamping mechanism is arranged above the mounting posts, the support posts are arranged in the middle above the clamping mechanism, and the plano-convex lens is placed above the support posts.

[0007] The clamping mechanism is composed of a bottom plate, a motor, a lead screw, fixed columns, a moving plate, a connecting seat, a first rotating shaft, a connecting rod, a second rotating shaft, an L-shaped connecting plate, a clamping plate, an anti-slip layer, a top plate, a slide rail and a pressure sensor. The bottom plate is fixedly connected above the mounting column, and a mounting groove is formed on the top surface of the mounting column for the motor to be installed inside. The motor is fixedly connected to the middle of the lower part of the bottom plate, and the lead screw is connected to the output end of the motor. The moving plate is threadedly connected to the outside of the lead screw, and the top plate is rotatably connected to the top surface of the lead screw.

[0008] It should be noted in the solution that the connecting seats are symmetrically and fixedly connected to the four sides of the moving plate. The first rotating shaft is fixedly connected above one side of the connecting seat, and the bottom end of the connecting rod is rotatably connected above the first rotating shaft.

[0009] Furthermore, it is worth noting that grooves for installing the slide rails are symmetrically formed on the top surface of the top plate. The slide rails are fixedly connected inside the grooves. The L-shaped connecting plate is fixedly connected above the slider matching the slide rail. The second rotating shaft is fixedly connected inside the short side of the L-shaped connecting plate, and the upper end of the connecting rod is rotatably connected to the outside of the second rotating shaft.

[0010] Even further, it should be noted that there are four fixed columns, and the fixed columns are fixedly connected between the bottom plate and the top plate. The moving plate is slidably connected to the fixed columns.

[0011] As a preferred implementation manner, the support column is fixedly connected to the middle of the upper part of the top plate.

[0012] As a preferred implementation manner, the anti-slip layer is fixedly connected to the side of the clamping plate close to the support column, and the material of the anti-slip layer is set as rubber material.

[0013] As a preferred implementation manner, the pressure sensor is fixedly connected inside the clamping plate, and the pressure sensor is electrically connected to the motor.

[0014] Compared with the prior art, a clamping device for processing plano-convex lenses provided by the present utility model has at least the following beneficial effects:

[0015] By means of the provided clamping mechanism, place the plano-convex lens above the support column, then control the motor to drive, and at the same time drive the four clamping plates to move towards each other until the clamping force between the pressure sensor and the plano-convex lens is detected, and immediately notify the motor to stop running. While ensuring stable clamping of the plano-convex lens, it avoids damage to the plano-convex lens caused by excessive clamping force, improves the use stability of the device, and further improves the work efficiency and processing quality.

Specific embodiments

[0020] The following further describes the present utility model in conjunction with embodiments.

[0021] Please refer to Figures 1-3 , the present utility model provides a clamping device for processing plano-convex lenses, including a base 1, a mounting hole 2, a mounting post 3, a clamping mechanism 4, a support post 5 and a plano-convex lens 6. The base 1 is evenly provided with mounting holes 2, the mounting post 3 is arranged inside the mounting hole 2, the clamping mechanism 4 is arranged above the mounting post 3, the support post 5 is arranged in the middle above the clamping mechanism 4, and the plano-convex lens 6 is placed above the support post 5.

[0022] The clamping mechanism 4 is composed of a bottom plate 401, a motor 402, a lead screw 403, a fixed post 404, a moving plate 405, a connecting seat 406, a first rotating shaft 407, a connecting rod 408, a second rotating shaft 409, an L-shaped connecting plate 410, a clamping plate 411, an anti-slip layer 412, a top plate 413, a slide rail 414 and a pressure sensor 415. The bottom plate 401 is fixedly connected above the mounting post 3, and a mounting groove is provided on the top surface of the mounting post 3. The motor 402 is fixedly connected to the middle of the lower surface of the bottom plate 401, and the mounting groove can be used to install the motor 402 inside. The lead screw 403 is connected to the output end of the motor 402, and the moving plate 405 is threadedly connected to the outside of the lead screw 403. The top plate 413 is rotatably connected to the top surface of the lead screw 403.

[0023] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3 , it is specifically noted that the connecting seats 406 are symmetrically and fixedly connected to the periphery of the moving plate 405, the first rotating shaft 407 is fixedly connected to the upper side of one side of the connecting seat 406, and the bottom end of the connecting rod 408 is rotatably connected above the first rotating shaft 407.

[0024] Furthermore, as shown inFigure 1 , Figure 2 and Figure 3 As shown in Figure 3 , it is worth specifically explaining that grooves for installing the slide rails 414 are symmetrically formed on the top surface of the top plate 413, the slide rails 414 are fixedly connected inside the grooves, the L-shaped connecting plate 410 is fixedly connected above the slider matching the slide rails 414, the second rotating shaft 409 is fixedly connected inside the short side of the L-shaped connecting plate 410, and the upper end of the connecting rod 408 is rotatably connected to the outside of the second rotating shaft 409.

[0025] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3 As shown in Figure 3 , it is worth specifically explaining that there are four fixing columns 404, and the fixing columns 404 are fixedly connected between the bottom plate 401 and the top plate 413, and the moving plate 405 is slidably connected to the fixing columns 404.

[0026] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3 As shown in Figure 3 , it is worth specifically explaining that the support column 5 is fixedly connected to the middle part above the top plate 413.

[0027] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3 As shown in Figure 3 , it is worth specifically explaining that the anti-slip layer 412 is fixedly connected to the side of the clamping plate 411 close to the support column 5, and the material of the anti-slip layer 412 is set as rubber material;

[0028] By setting the rubber material, the friction force can be increased, reducing sliding and accidents; at the same time, rubber has good elasticity, which can effectively absorb and disperse the impact force, protecting the plano-convex lens from being damaged by impact.

[0029] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3 As shown in Figure 3 , it is worth specifically explaining that the pressure sensor 415 is fixedly connected inside the clamping plate 411, and the pressure sensor 415 is electrically connected to the motor 402;

[0030] By setting the pressure sensor 415, the clamping force between the clamping plate 411 and the plano-convex lens 6 can be detected, avoiding that the plano-convex lens 6 may be subjected to unnecessary pressure due to excessive clamping force, affecting its optical performance or causing damage; if the clamping force is too small, the plano-convex lens 6 may not be firmly fixed, resulting in loosening or falling off during processing or use, improving the clamping force stability of the mechanism.

[0031] The present solution has the following working process: When in use, first insert the mounting post 3 into the interior of the mounting hole 2, then place the plano-convex lens 6 above the support post 5, and then drive the motor 402 to drive the lead screw 403 to rotate. Since the moving plate 405 is threadedly rotatably connected to the outside of the lead screw 403 and is simultaneously slidably connected to the outside of the fixed post 404 through the connecting seat 406, the rotation of the connecting seat 406 can be restricted to prevent the moving plate 405 from rotating with the lead screw 403, ensuring that the connecting seat 406 moves up and down outside the fixed post 404. The downward movement of the connecting seat 406 drives the connecting rod 408 to rotate, and the L-shaped connecting plate 410 is slidably connected above the slide rail 414, thereby driving the L-shaped connecting plate 410 to drive the clamping plate 411 to move towards the support post 5, and tightly clamp against the outer wall of the plano-convex lens 6 through the anti-slip layer 412. At the same time, the pressure sensor 415 detects the clamping force between it and the plano-convex lens 6 and immediately notifies the motor 402 to stop running. At this time, the stability of the clamping of the plano-convex lens 6 can be ensured, and damage to the plano-convex lens 6 caused by excessive clamping force can be avoided. Similarly, driving the motor 402 to rotate in the reverse direction can release the clamping of the clamping plate 411 on the plano-convex lens 6, facilitating the staff to remove the processed plano-convex lens 6.

[0032] In summary: Through the set clamping mechanism 4, place the plano-convex lens 6 above the support post 5, then control the motor 402 to drive, and simultaneously drive the four clamping plates 411 to move towards each other until the pressure sensor 415 detects the clamping force between it and the plano-convex lens 6, and immediately notify the motor 402 to stop running. While ensuring stable clamping of the plano-convex lens 6, damage to the plano-convex lens 6 caused by excessive clamping force can be avoided, improving the use stability of the device, and further improving work efficiency and processing quality.
