Description

Technical Field

[0001] This utility model relates to the field of mounting base technology, and in particular to a base for a lens inspection stage. Background Technology

[0002] The base of the lens inspection station is the core basic component supporting the entire lens inspection equipment. Its main function is to provide a stable and rigid mounting carrier for the main structure of the inspection station and optical inspection components (such as lenses, light sources, sensors, etc.). It is usually made of materials such as cast iron, marble, or high-rigidity alloys.

[0003] Existing technologies suffer from minor vibrations caused by the operation of equipment and personnel walking on the workshop floor. These minor vibrations can be directly transmitted to the lens-bearing platform through the base, causing the lens to slip or deflect at an angle on the bearing surface. Therefore, multiple damping springs are usually used to achieve a vibration reduction effect. However, damping springs cannot absorb all vibrations, which can still be directly transmitted to the base through the damping springs. This cannot effectively attenuate the vibration energy, which can affect the recording effect in long-lens applications. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a base for a lens inspection stage.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a base for a lens inspection stage, comprising: A base plate, on which a rubber frame is slidably connected. A multi-directional shock absorption assembly includes an installation chamber fixedly connected to a rubber frame. A sealing plate is slidably connected inside the installation chamber. The sealing plate is connected to an extension rod via a transmission rod. A snap-fit ​​plate is fixedly connected to the extension rod. An inner chamber is slidably connected to the snap-fit ​​plate. A vertical rod is fixedly connected to the snap-fit ​​plate via a series rod. A rotating disk and a fixed disk are slidably connected to the vertical rod. A turning block is connected to the rotating disk via a toggle rod. A counterweight ball is connected to the bottom of the inner chamber via an elastic rope.

[0006] In a preferred embodiment, a damping spring is fixedly connected to the base plate, a fastening ring is fixedly connected to the damping spring, the rubber frame is slidably embedded in the fastening ring, an air pump is installed on the base plate, the output end of the air pump is fixedly connected to the rubber frame through an air supply pipe, and a through hole is provided on the fastening ring for the air supply pipe to pass through.

[0007] The above technical solution is adopted: by setting a damping spring, the bottom of the fastener is limited; the rubber frame is slidably embedded in the fastening ring to prevent it from falling off; the air pump supplies air to the rubber frame through the air supply pipe, causing the rubber frame to expand; after the sealing plate is separated, air is quickly supplied to the installation chamber, causing the rubber ring to drive the inner chamber to rise.

[0008] In a preferred embodiment, universal joints are fixedly connected to both ends of the transmission rod, and the ends of the two universal joints away from the transmission rod are fixedly connected to the sealing plate and the extension rod, respectively. A rubber ring is fixedly connected to the bottom of the inner compartment, and the rubber ring is slidably connected inside the installation compartment.

[0009] The above technical solution allows for more flexible connection between the sealing plate, extension rod, and transmission rod by fixing universal joints at both ends of the transmission rod during use.

[0010] In a preferred embodiment, the inner compartment is provided with a sliding hole adapted to the snap-fit ​​plate, the inner compartment is provided with an annular limiting groove for limiting the rotation disk, the fixed disk is fixedly connected to the inner compartment, the rotating block is fixedly connected with a transverse rod, the transverse rod is provided with a hole for the sliding rod to pass through, and the mounting compartment is provided with a transverse through hole for the transverse rod to slide.

[0011] The above technical solution is adopted: during use, a sliding hole adapted to the snap-fit ​​plate is opened on the inner compartment, which facilitates the snap-fit ​​plate to slide on the inner compartment and avoids it being blocked. The limiting groove inside the inner compartment makes the rotating disk stuck inside the inner compartment.

[0012] In a preferred embodiment, the inner compartment is provided with an arc-shaped groove, and the actuating rod passes through the arc-shaped groove of the inner compartment and is fixedly connected to the rotating disk.

[0013] The above technical solution allows the arc-shaped groove on the inner compartment to facilitate the sliding of the lever within it.

[0014] In a preferred embodiment, a guide rail is fixedly connected inside the installation chamber, and elastic ropes are fixedly connected to the top and bottom of the counterweight ball. The end of the top elastic rope away from the counterweight ball is fixedly connected to the inner chamber, and the end of the bottom elastic rope away from the counterweight ball is fixedly connected to the guide rail. A limit frame is fixedly connected to the side of the bottom elastic rope near the guide rail.

[0015] The above technical solution involves fixing the elastic rope at the bottom of the counterweight ball inside the installation chamber with a guide rail, thus preventing the counterweight ball from shaking too much and hitting the inner wall of the chamber or hitting each other.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention features an installation chamber. The bottom of the testing platform is inserted into the installation chamber, connecting its bottom to the inner chamber. An air pump is activated, inflating the rubber frame through an air supply pipe until it is full. The elastic deformation of the rubber frame provides initial shock absorption while maintaining gas pressure to prevent hard contact between the testing platform and the installation chamber. Then, a turning block is tightened, causing the horizontal rod to move inward. This, in turn, drives the vertical rod along the horizontal hole of the fixed plate via a toggle rod and rotating disc, clamping the bottom of the testing platform with the two side clamping plates. The testing platform is then installed using the turning block, preventing lateral movement. At this point, the testing platform is fixed, and the rubber ring presses against the inner wall of the installation chamber. During this process, the extension rod moves inward, driving the transmission rod to push the rubber ring outward, separating the two sealing plates. The gas inside the rubber frame lifts the inner chamber, causing the sealing plates to separate. The gas inside the rubber frame flows to the bottom of the inner chamber, supporting it. Even after the testing platform is installed, gas support can further enhance the shock absorption effect, preventing wear on the bottom of the testing platform and preventing the inner chamber (supporting the testing platform) from vibrating synchronously with the installation chamber. Compared to existing technologies, this invention improves the device's vibration damping capability. Attached Figure Description

Detailed Implementation

[0024] 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 protection scope of the present utility model.

[0025] like Figures 1 to 6 As shown, this utility model provides a technical solution: a base for a lens inspection stage, comprising: Base plate 1, with a rubber frame 12 slidably connected to it. The multi-directional shock absorption assembly 2 includes an installation chamber 21 fixedly connected to the rubber frame 12. A sealing plate 27 is slidably connected inside the installation chamber 21. An extension rod 24 is connected to the sealing plate 27 via a transmission rod 25. A snap-fit ​​plate 23 is fixedly connected to the extension rod 24. An inner chamber 22 is slidably connected to the snap-fit ​​plate 23. A vertical rod 219 is fixedly connected to the snap-fit ​​plate 23 via a series rod 218. A rotating disk 216 and a fixed disk 217 are slidably connected to the vertical rod 219. A turning block 213 is connected to the rotating disk 216 via a toggle rod 215. A counterweight ball 29 is connected to the bottom of the inner chamber 22 via an elastic rope 210.

[0026] In use, this invention first establishes initial power transmission through the air pump 3. After the air pump 3 starts, gas is transmitted to the rubber frame 12 via the air supply pipe 31, causing the rubber frame 12 to inflate fully and providing a pressure foundation for subsequent cushioning and lifting. The operator turns the turning block 213, converting the rotational motion into a linear inward displacement of the transverse rod 214 (the transverse rod 214 slides along the transverse through hole of the mounting chamber 21). The transverse rod 214 is slidably connected to the actuating rod 215, causing the actuating rod 215 to move along the arc groove of the inner chamber 22, thereby pushing the rotating disk 216 to slide in the annular limiting groove of the inner chamber 22. The rotating disk 216 forms a guide transmission with the vertical rod 219 through the inclined groove on it, converting the sliding of the rotating disk 216 into a linear movement of the vertical rod 219 along the transverse hole of the fixed disk 217, causing the vertical rods 219 on both sides to clamp inward, and finally driving the snap-fit ​​plate 23 to move inward synchronously along the sliding hole of the inner chamber 22, realizing the clamping and fixing of the bottom of the testing table (during this process, the edge of the rubber ring 212 simultaneously abuts against the inner wall of the mounting chamber 21, enhancing the structural stability). When the snap-fit ​​plate 23 is displaced, it drives the extension rod 24 to move inward through the rigid connection. The extension rod 24 drives the transmission rod 25 to move through the flexible transmission of the universal joints 26 at both ends, thereby pushing the sealing plate 27 to separate outward and release the initial snap-fit ​​state. At this time, the filling gas in the rubber frame 12 forms pressure transmission through the gap of the separated sealing plate 27, pushing the rubber ring 212 upward, and finally driving the inner chamber 22 to rise slightly. The opening on the installation chamber 21 cooperates with the sealing ring and the extension rod 24 to slide and seal, ensuring effective transmission of gas pressure.

[0027] A damping spring 11 is fixedly connected to the base plate 1, and a fastening ring 13 is fixedly connected to the damping spring 11. The rubber frame 12 is slidably embedded in the fastening ring 13. An air pump 3 is installed on the base plate 1. The output end of the air pump 3 is fixedly connected to the rubber frame 12 through an air supply pipe 31. A through hole is opened on the fastening ring 13 for the air supply pipe 31 to pass through. By setting the damping spring 11, the bottom of the fastener is limited. The rubber frame 12 is slidably embedded in the fastening ring 13 to prevent it from falling off. The air pump 3 supplies air to the rubber frame 12 through the air supply pipe 31, causing the rubber frame 12 to expand. After the sealing plate 27 is separated, air is quickly supplied to the installation chamber 21, causing the rubber ring 212 to drive the inner chamber 22 to rise.

[0028] Furthermore, such as Figures 2 to 5 As shown, universal joints 26 are fixedly connected to both ends of the transmission rod 25. The ends of the two universal joints 26 away from the transmission rod 25 are fixedly connected to the sealing plate 27 and the extension rod 24, respectively. A rubber ring 212 is fixedly connected to the bottom of the inner compartment 22. The rubber ring 212 is slidably connected in the installation compartment 21. In use, by fixing universal joints 26 to both ends of the transmission rod 25, the connection between the sealing plate 27, the extension rod 24 and the transmission rod 25 is more flexible.

[0029] like Figures 3 to 5As shown, the inner compartment 22 has a sliding hole adapted to the snap-fit ​​plate 23, and the inner compartment 22 has an annular limiting groove for limiting the rotation disk 216. The fixed disk 217 is fixedly connected to the inner compartment 22. The rotating block 213 is fixedly connected to a horizontal rod 214. The horizontal rod 214 has a hole for the sliding rod 215 to slide through. The mounting compartment 21 has a horizontal through hole for the horizontal rod 214 to slide. In use, the sliding hole adapted to the snap-fit ​​plate 23 in the inner compartment 22 facilitates the sliding of the snap-fit ​​plate 23 in the inner compartment 22 and prevents it from being blocked. The limiting groove inside the inner compartment 22 makes the rotation disk 216 snap into the inner compartment 22.

[0030] like Figure 4 As shown, an arc-shaped groove is provided on the inner compartment 22. The actuating rod 215 passes through the arc-shaped groove of the inner compartment 22 and is fixedly connected to the rotating disk 216. The arc-shaped groove on the inner compartment 22 facilitates the sliding of the actuating rod 215 therein.

[0031] like Figure 3 As shown, a guide rail 28 is fixedly connected inside the installation chamber 21. Elastic ropes 210 are fixedly connected to the top and bottom of the counterweight 29. The end of the top elastic rope 210 away from the counterweight 29 is fixedly connected to the inner chamber 22, and the end of the bottom elastic rope 210 away from the counterweight 29 is fixedly connected to the guide rail 28. A limit frame 211 is fixedly connected to the side of the bottom elastic rope 210 near the guide rail 28. The elastic rope 210 at the bottom of the counterweight 29 is fixed by the guide rail 28 fixedly connected inside the installation chamber 21.

[0032] Working principle: like Figure 1-6 As shown, when in use, insert the bottom of the testing platform directly into the installation chamber 21 so that its bottom is connected to the inner chamber 22, start the air pump 3 so that the air pump 3 inflates the rubber frame 12 through the air supply pipe 31, so that the rubber frame 12 is in a fully inflated state. The operator turns the turning block 213, causing the turning block 213 to drive the horizontal rod 214 to move inward, which in turn drives the actuating rod 215 to move, causing the actuating rod 215 to drive the rotating disk 216 to slide, causing the inclined groove on the rotating disk 216 to drive the vertical rod 219 to slide, causing the vertical rod 219 to slide in the horizontal hole on the fixed disk 217, causing the vertical rods 219 on both sides to be driven to move inward and clamp, and the vertical rods 219 to slide at the bottom of the test table, causing the clamping plate 23 to move inward and clamp, so that the clamping plate 23 clamps the bottom of the test table, and the edge of the rubber ring 212 abuts against the inner wall of the installation chamber 21 through the rubber ring; During this process, the extension rod 24 will be driven to move inward, causing the extension rod 24 to drive the transmission rod 25 to move, which in turn causes the transmission rod 25 to drive the rubber ring 212 to move outward, causing the two interlocking sealing plates 27 to separate. This causes the gas inside the rubber frame 12 to rise and press against 212, causing the inner chamber 22 to be lifted slightly. The rubber frame 12 has an opening and a sealing ring to press against the extension rod 24. The actuating rod 215 will be driven to rotate inevitably by the rotating disk 216. At this time, the transverse rod 214 will slide synchronously around the installation chamber 21 through the opening.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
