Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and in particular to a stabilizing fixing device for anti-shaking lens processing. Background Technology

[0002] In modern optics, lenses, as key optical components, are widely used in various optical devices such as cameras, projectors, and microscopes. The manufacturing precision of lenses plays a decisive role in the imaging quality and performance of optical devices. During lens manufacturing, the fixing device is an important piece of equipment to ensure manufacturing precision, and its stability directly affects the manufacturing quality of the lens.

[0003] Existing lens processing fixtures typically use two clamping plates to hold and fix circular lenses during positioning. However, this method can only provide limited clamping force from both sides, making the circular lens prone to movement during processing. This reduces the fixing effect of the fixture. In addition, most of these fixtures rely on screws to drive the clamping plates to achieve the clamping action. During processing, due to the continuous action of external forces such as cutting forces and vibrations, the screws are very prone to loosening, which weakens the clamping force of the clamping plates on the lens, causing the lens to wobble and affecting the processing accuracy and quality of the lens. Utility Model Content

[0004] This utility model relates to a stable fixing device for anti-shaking lens processing. It solves the problem that existing fixing devices for lens processing usually use two clamping plates to hold a circular lens. Because only the two sides provide limited clamping force, the lens is prone to movement during processing, which reduces the fixing effect. Moreover, such fixing devices mostly rely on screws to drive the clamping plates. Under the influence of external forces, the screws are prone to loosening, causing the lens to shake and affecting the processing accuracy and quality of the lens.

[0005] The first aspect of this utility model provides a stabilizing and fixing device for anti-shake lens processing, specifically comprising: a base, wherein a top seat is fixedly connected to the upper end face of the base via a fixing frame; the top surface of the top seat has eight strip-shaped openings arranged in a circular array, and each strip-shaped opening has a strip-shaped groove inside; a fixing component is provided between the base and the top seat, and an anti-shake mechanism is installed on the fixing component; the fixing component includes fixing clamps, the number of fixing clamps is eight, and a sliding block is fixedly connected to the bottom of each fixing clamp, the sliding block is slidably connected to the strip-shaped opening, each sliding block is provided with a rectangular slider slidably connected to the strip-shaped groove, the lower end of each sliding block is rotatably connected to a connecting rod via a rotating shaft, and the other end of the connecting rod is rotatably connected to the outer circumference of a nut via a rotating shaft, and a screw is threadedly connected inside the nut, and the screw is rotatably connected between the base and the top seat.

[0006] Furthermore, each of the fixed clamping blocks is provided with a rubber clamping block on its clamping surface, and an arc-shaped clamping opening is provided on the clamping surface of the rubber clamping block.

[0007] Furthermore, the anti-sway mechanism includes a rectangular sliding shell and a locking gear. The rectangular sliding shell is fixedly connected to the upper surface of the base by an L-shaped fixing bracket, and a guide slider is slidably connected inside the rectangular sliding shell. A top block penetrating the right side wall of the rectangular sliding shell is provided on the right end face of the guide slider, and a locking block is provided on the right end face of the top block. The locking gear is fixedly connected to the lower part of the outer peripheral surface of the screw. A rotating rod is rotatably connected to the left end face of the guide slider, and the rotating rod penetrates the left side wall of the rectangular sliding shell. A metal limiting block is fixedly connected to the left end of the rotating rod. A limiting plate is fixedly connected to the left side of the front end face of the rectangular sliding shell, and two rectangular notches are opened on the left side of the upper end face of the limiting plate.

[0008] Furthermore, two magnets are fixedly connected to the front end face of the limiting plate below the two rectangular notches; when the metal limiting block is in the limiting state, the metal limiting block is magnetically attracted to one of the magnets.

[0009] Furthermore, when the anti-sway mechanism is in the locking limit state, the locking block engages with the locking gear.

[0010] This utility model provides a stabilizing and fixing device for anti-shake lens processing, which has the following beneficial effects:

[0011] This invention, through the setting of the fixing component, enables the rotation of the screw when fixing a circular lens. This causes the nut to move downwards along the lower end of the connecting rod under the action of the thread. Then, the upper end of the connecting rod simultaneously brings eight fixing blocks towards the center of the top seat, achieving all-round clamping and fixing of the circular lens. Compared with the existing two-sided clamping method, this structure can provide balanced clamping force to the outer periphery of the circular lens from eight directions, effectively limiting the movement of the lens during processing and effectively improving the stability and reliability of this fixing device.

[0012] This invention, through the setting of an anti-shaking mechanism, allows a metal limiting block to be inserted into a rectangular notch on the right side after the circular lens is clamped and fixed. At this time, the locking gear meshes with the locking block, so that the locking gear and the screw are effectively locked and limited, preventing the screw from loosening due to external force, and preventing the clamping force of the fixing block from weakening due to the loosening of the screw. This eliminates the phenomenon of lens shaking and improves the precision of lens processing and the quality of finished products. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figures 1 to 6 :

[0027] This utility model proposes a stabilizing and fixing device for anti-shaking lens processing, comprising: a base 1, with a top seat 102 fixedly connected to the upper end face of the base 1 via a fixing frame 101; the top surface of the top seat 102 has eight strip-shaped openings 103 arranged in a circular array, and each strip-shaped opening 103 has a strip-shaped sliding groove 104 inside; a fixing component 2 is provided between the base 1 and the top seat 102, and an anti-shaking mechanism 3 is installed on the fixing component 2; the fixing component 2 includes eight fixing clamps 201, and each fixing clamp 201 has a sliding block 202 fixedly connected to its bottom, the sliding block 202 and the... The strip-shaped through-hole 103 is slidably connected. Each sliding block 202 is provided with a rectangular slider 207 that is slidably connected to the strip-shaped slide groove 104. The lower end of each sliding block 202 is rotatably connected to a connecting rod 203 via a rotating shaft. The other end of the connecting rod 203 is rotatably connected to the outer circumference of the nut 204 via a rotating shaft. The nut 204 is internally connected to a screw 205 via a thread. The screw 205 is rotatably connected between the base 1 and the top seat 102. With the setting of the fixing component 2, the circular lens can be clamped and fixed in all directions, effectively limiting the movement of the lens during processing and improving the stability and reliability of the fixing device.

[0028] Each fixed clamping block 201 has a rubber clamping block 206 on its clamping surface, and the rubber clamping block 206 has an arc-shaped clamping opening on its clamping surface; a handwheel is fixedly connected to the lower outer side of the screw 205 to facilitate the rotation of the screw 205.

[0029] Example 2, based on Example 1, such as Figure 1 , Figure 5 and Figure 6 As shown, the anti-sway mechanism 3 includes a rectangular sliding shell 301 and a locking gear 302. The rectangular sliding shell 301 is fixedly connected to the upper surface of the base 1 by an L-shaped fixing bracket. A guide slider 303 is slidably connected inside the rectangular sliding shell 301. A top block 304 is provided on the right end face of the guide slider 303, penetrating the right side wall of the rectangular sliding shell 301. A locking block 305 is provided on the right end face of the top block 304. The locking gear 302 is fixedly connected to the lower part of the outer peripheral surface of the screw 205. A rotating rod 306 is rotatably connected to the left end face of the guide slider 303, and the rotating rod 306 penetrates the left side of the rectangular sliding shell 301. On the side wall, a metal limiting block 307 is fixedly connected to the left end of the rotating rod 306, and a limiting plate 308 is fixedly connected to the left side of the front end face of the rectangular sliding shell 301. Two rectangular notches 309 are opened on the left side of the upper end face of the limiting plate 308. When the anti-shaking mechanism 3 is in the locking and limiting state, the locking block 305 meshes with the locking gear 302. Through the setting of the anti-shaking mechanism 3, after the circular lens is clamped and fixed, the locking gear 302 and the screw 205 can be effectively locked and limited, preventing the screw 205 from loosening due to external force, and improving the precision of lens processing and the quality of finished products.

[0030] Two magnets 3010 are fixedly connected to the front end of the limiting plate 308 on the lower side of the two rectangular notches 309. When the metal limiting block 307 is in the limiting state, the metal limiting block 307 is magnetically attracted to one of the magnets 3010, which prevents the metal limiting block 307 from separating from the rectangular notch 309 on its own due to external forces such as vibration. Therefore, the locking and limiting effect of the anti-shaking mechanism 3 is further improved.

[0031] The working principle of this embodiment is as follows: In use, first, place the circular lens on the middle side of the top surface of the top seat 102, between the eight fixed clamping blocks 201. Then, manually rotate the front end of the metal limiting block 307 upwards, causing the metal limiting block 307 to leave the inside of a rectangular notch 309 on the right. Next, move the metal limiting block 307 to the left, moving the rotating rod 306, guide slider 303, top block 304, and locking gear 302 to the left. When the metal limiting block 307 has moved to the left and is above a rectangular notch 309 on the left, rotate the front end of the metal limiting block 307 downwards, causing the metal limiting block to... The positioning block 307 is inserted into a rectangular notch 309 on the left side, and at this time the locking gear 302 is separated from the locking block 305. Then, the screw 205 is rotated by the handwheel on the screw 205. At this time, the nut 204 moves downward with the lower end of the connecting rod 203 under the action of the thread. Then, the upper end of the connecting rod 203 moves the eight fixing blocks 201 together towards the center of the top seat 102, thereby clamping and fixing the circular lens. At this time, it can provide clamping force in eight directions around the outside of the circular lens, preventing the circular lens from moving during the processing, thereby improving the fixing effect of this fixing device.

[0032] After the circular lens is clamped and fixed, the front end of the metal limiting block 307 is rotated upward, causing the metal limiting block 307 to leave the inside of a rectangular notch 309 on the left. Then, the metal limiting block 307 is moved to the right, moving the rotating rod 306, guide slider 303, top block 304, and locking gear 302 to the right. When the metal limiting block 307 moves to the right and is above a rectangular notch 309 on the right, the front end of the metal limiting block 307 is rotated downward, causing the metal limiting block 307 to engage with the rectangular notch 309 on the right. At this time, the locking gear 302 meshes with the locking block 305, effectively locking and limiting the locking gear 302 and the screw 205. This prevents the screw 205 from loosening due to external force, avoids weakening the clamping force of the fixing block 201 on the lens, and prevents the lens from shaking. Therefore, the processing accuracy and quality of the lens are effectively improved.
