Abstract
Description
Technical Field
[0001] This utility model relates to the field of precision measurement technology, specifically to a precision measurement device for optical components. Background Technology
[0002] Precision measuring devices for optical components are equipment used to accurately measure the geometric parameters and optical performance of various optical elements (such as lenses, prisms, filters, etc.).
[0003] However, current precision measuring devices for optical components still have the following shortcomings: In many precision measuring devices for optical components, the measuring lenses are mostly directly exposed to the external environment. When the equipment is in a static and non-operating state, dust and tiny impurities in the air will gradually accumulate and cover the lens surface. Even when the instrument is working and the measuring lens has the function of moving, dust will still adhere to the lens. Once the lens surface is covered by dust, it will affect the measurement accuracy. This is because dust will change the propagation path of light, scatter or absorb some light, and thus cause deviations in the measurement data. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a precision measuring device for optical components, which can completely seal the measuring lens when not in use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision measuring device for optical components, comprising a precision measuring machine, a connecting tube connected to the precision measuring machine, and a measuring lens connected to the connecting tube. The measuring lens has first sliding grooves on both sides of its outer wall, and two first sliding blocks are slidably connected within each of the two first sliding grooves. The outer walls of the two first sliding blocks are fixedly connected to the same U-shaped cover. A top cover is installed at the upper end of the U-shaped cover, and a bottom cover is installed at the lower end of the U-shaped cover.
[0006] Furthermore, the upper surfaces of both first sliders are parallel to the upper end of the U-shaped cover, and the lower surfaces of both first sliders are located inside the U-shaped cover and above the lower end of the U-shaped cover. The top cover is a rectangular cover with a central through hole, and the inner wall of the central through hole of the top cover is slidably connected to the outer wall of the connecting pipe.
[0007] Furthermore, a rectangular mounting groove is formed through the outer wall of one side frame of the U-shaped cover in the area where the first slider is located. A second sliding groove is formed on both sides of the rectangular mounting groove on the outer wall of one side frame of the U-shaped cover, and the second sliding groove extends to the inner wall of the opposite side frame of the U-shaped cover where the rectangular mounting groove is located. A second slider is slidably connected in both of the two second sliding grooves. The outer walls of the two second sliders are fixed to the two sides of the bottom cover. The bottom cover is set as an L-shaped plate composed of a vertical plate and a horizontal plate. The vertical plate of the bottom cover slides in the rectangular mounting groove, and the horizontal plate of the bottom cover slides in both the rectangular mounting groove and the U-shaped cover.
[0008] Furthermore, a cleaning component is installed on the side of the horizontal plate of the bottom cover away from the vertical plate. The cleaning component can be either a cleaning cloth or a cleaning sponge, and the upper surface of the cleaning component is in contact with the lower surface of the measuring lens.
[0009] Furthermore, a handle frame is fixed to the outer wall of the vertical plate of the bottom cover, and the surface of the handle frame is provided with anti-slip texture.
[0010] Furthermore, a first T-shaped rotating shaft is fixedly connected to the outer wall of the U-shaped cover above one of the second sliders. The first T-shaped rotating shaft is a combination of a cylinder and a disc. A locking block is rotatably connected to the outer wall of the cylinder in the first T-shaped rotating shaft. A slot is opened at the end of the surface of the second slider located on one side of the first T-shaped rotating shaft that runs through the top and bottom of the second slider. The slot is adapted to the shape and size of the locking block. The slot is located in the area between the cleaning component and the handle frame and is close to the cleaning component. The locking block is located in the slot and engaged.
[0011] Furthermore, a second T-shaped rotating shaft is fixedly connected to the outer wall of the connecting pipe. The second T-shaped rotating shaft is a combination of a cylinder and a disc. An L-shaped baffle is rotatably connected to the outer wall of the cylinder in the second T-shaped rotating shaft. The L-shaped baffle is also slidably connected to the outer wall of the cylinder in the second T-shaped rotating shaft. The L-shaped baffle is a horizontal support plate and a vertical support plate. A retaining groove is formed through the outer wall of the horizontal support plate on the side away from the connecting pipe. The retaining groove also penetrates the upper surface of the horizontal support plate. A retaining rod is fixedly connected to the side wall of the U-shaped cover. The retaining rod is adapted to the shape, size and position of the retaining groove. A threaded groove is formed on the surface of the horizontal support plate on the side away from the vertical plate. The threaded groove penetrates the retaining groove into the horizontal plate. The threaded groove also penetrates the retaining rod. A threaded rod is threadedly inserted into the threaded groove.
[0012] Furthermore, each of the four corners of the top cover is threaded with a second fastening bolt, which penetrates the top cover and extends into the frame of the U-shaped cover for bolt fastening.
[0013] Furthermore, the lower surface of the bottom cover is threaded with a first fastening bolt, which penetrates the bottom cover and extends into the cleaning component for bolt fastening.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This utility model, through the cooperation of the U-shaped cover, top cover and bottom cover, can form a closed environment when the precision measuring machine is in standby mode, completely enclosing the measuring lens and separating it from the external environment, reducing the interference of dust and other impurities on the measurement data. The structure is simple, easy to operate and highly practical.
[0016] 2. This utility model utilizes the cooperation of the second slider, bottom cover, cleaning component, and first slider. When the measuring lens needs cleaning, the cleaning component on the bottom cover is moved using the handle frame and second slider, allowing it to wipe the lens surface. Additionally, the first slider controls the up-and-down movement of the U-shaped cover. When the user wants to block some light while the measuring lens is working, the U-shaped cover can be moved down to reduce the light diffusion range. Simultaneously, the bottom cover is removed and secured in a slot with a locking block, preventing further movement and ensuring uninterrupted lens operation. Conversely, when the user does not want to block light while the measuring lens is working, the U-shaped cover can be moved up, with the L-shaped baffle blocking the baffle bar on the U-shaped cover and secured with a threaded rod, ensuring it does not affect the light irradiation range. These two modes meet different needs and can improve equipment safety to a certain extent. Attached Figure Description

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] like Figures 1 to 11 As shown, a precision measuring device for optical components includes a precision measuring machine 1, a connecting tube 2 connected to the precision measuring machine 1, and a measuring lens 3 connected to the connecting tube 2. The measuring lens 3 has first sliding grooves 4 on both sides of its outer wall. First sliders 5 are slidably connected in both first sliding grooves 4. The outer walls of the two first sliders 5 are fixed to the same U-shaped cover 6. A top cover 7 is installed at the upper end of the U-shaped cover 6, and a bottom cover 11 is installed at the lower end of the U-shaped cover 6.
[0031] like Figures 1 to 11 As shown, when using the precision measuring device for optical components in this utility model, the U-shaped cover 6 is first lowered to cover the periphery of the measuring lens 3. Then, the U-shaped cover 6, the top cover 7, and the bottom cover 11 form a closed environment to completely enclose the measuring lens 3, separating it from the external environment, reducing the interference of dust and other impurities on the measurement data, and improving the accuracy of the data.
[0032] It is worth noting that all connections between the U-shaped cover 6 and the top cover 7 and bottom cover 11 are fitted with elastic seals to enhance the sealing effect.
[0033] like Figure 2 , Figure 4 and Figure 5 As shown, the upper surfaces of the two first sliders 5 are parallel to the upper end of the U-shaped cover 6, and the lower surfaces of the two first sliders 5 are located inside the U-shaped cover 6 and above the lower end of the U-shaped cover 6. The top cover 7 is a rectangular cover with a central through hole. The inner wall of the central through hole of the top cover 7 is slidably connected to the outer wall of the connecting pipe 2, which allows the top cover 7 to slide even when it blocks the top of the measuring lens 3, and the bottom cover 11 is not blocked by the first sliders 5.
[0034] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a rectangular mounting groove 8 is provided through the outer wall of one side of the U-shaped cover 6 in the area where the first slider 5 is located. On both sides of the outer wall of one side of the U-shaped cover 6, there are second sliding grooves 9 that are connected to the rectangular mounting groove 8. The second sliding grooves 9 extend to the inner wall of the opposite side of the U-shaped cover 6 where the rectangular mounting groove 8 is located. A second slider 10 is slidably connected in both second sliding grooves 9. The outer walls of the two second sliders 10 are fixed to both sides of the bottom cover 11. The bottom cover 11 is an L-shaped plate composed of a vertical plate and a horizontal plate. The vertical plate of the bottom cover 11 slides in the rectangular mounting groove 8, and the horizontal plate of the bottom cover 11 slides in both the rectangular mounting groove 8 and the U-shaped cover 6.
[0035] Specifically, after the U-shaped cover 6 and the top cover 7 have slid down into place, the bottom cover 11 is manually pushed inward using the second slider 10 to close it. Together with the U-shaped cover 6 and the top cover 7, a sealed space is formed, completely enclosing the measuring lens 3 and separating it from the external environment. When it needs to be opened, it can be pulled outward.
[0036] like Figure 5 , Figure 6 and Figure 7 As shown, a cleaning component 12 is installed on the side of the horizontal plate of the bottom cover 11 away from the vertical plate. The cleaning component 12 can be either a cleaning cloth or a cleaning sponge. The upper surface of the cleaning component 12 is in contact with the lower surface of the measuring lens 3.
[0037] Specifically, after the precision measuring machine 1 finishes its work, it can be manually pushed inward and pulled outward multiple times to make the cleaning component 12 continuously wipe the mirror surface of the measuring lens 3, making the mirror surface cleaner and improving the data accuracy of the precision measuring machine 1 to a certain extent. In addition, the cleaning component 12 can be selected from two materials with specific cleaning properties, namely cleaning cloth and cleaning sponge, to meet specific cleaning needs. Manufacturers can choose the appropriate cleaning component 12 for production according to actual conditions.
[0038] like Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, a handle frame 13 is fixed to the outer wall of the vertical plate of the bottom cover 11, and the surface of the handle frame 13 is provided with anti-slip texture.
[0039] Specifically, by using the handle frame 13, the bottom cover 11, and the cleaning component 12, it is more convenient and improves the user experience. In addition, the anti-slip texture increases friction and reduces the occurrence of slippage.
[0040] like Figure 9 and Figure 10 As shown, the outer wall of the U-shaped cover 6 is fixed above one of the second sliders 10 with a first T-shaped rotating shaft 14. The first T-shaped rotating shaft 14 is a combination of a cylinder and a disc. The outer wall of the cylinder in the first T-shaped rotating shaft 14 is rotatably connected to a locking block 15. The surface of the second slider 10 located on one side of the first T-shaped rotating shaft 14 is provided with a slot 16 that runs through the top and bottom of the second slider 10. The slot 16 is adapted to the shape and size of the locking block 15. The slot 16 is located in the area between the cleaning component 12 and the handle frame 13, and is close to the cleaning component 12. The locking block 15 is located in the slot 16 and is locked in place.
[0041] Specifically, after the bottom cover 11 is pulled out, the locking block 15 and the slot 16 can lock the bottom cover 11 into place and prevent it from moving. In this way, when the precision measuring machine 1 moves the measuring lens 3, it will not affect the measurement operation. At the same time, it will not affect the up and down movement of the U-shaped cover 6. In addition, when the U-shaped cover 6 is closed, the locking block 15 can block the bottom cover 11 and prevent it from moving freely in the horizontal direction.
[0042] It is worth noting that although the cleaning component 12 is located inside the U-shaped cover 6, it does not contact the measuring lens 3 when it is not in operation. When the cleaning component 12 is not in operation, it is in contact with the part of the first slider 5 extending out of the first groove 4. However, it will only come into contact with the mirror surface of the measuring lens 3 for wiping when it is in operation. In addition, even if the bottom cover 11 is moved outward and is locked by the slot 16 and the block 15, the cleaning component 12 still needs to be kept inside the U-shaped cover 6 and not in contact with the measuring lens 3. This is to prevent dirt on the cleaning component 12 from staying on the mirror surface and external impurities from staying on the cleaning component 12.
[0043] In addition, both the outer wall of the card block 15 and the inner wall of the card slot 16 are provided with protrusions to increase friction and enhance their limiting ability.
[0044] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 8 and Figure 11 As shown, a second T-shaped rotating shaft 19 is fixed to the outer wall of the connecting pipe 2. The second T-shaped rotating shaft 19 is a combination of a cylinder and a disc. An L-shaped baffle 20 is rotatably connected to the outer wall of the cylinder in the second T-shaped rotating shaft 19. The L-shaped baffle 20 is also slidably connected to the outer wall of the cylinder in the second T-shaped rotating shaft 19. The L-shaped baffle 20 is a horizontal support plate and a vertical support plate. A retaining groove 22 is opened through the outer wall of the horizontal support plate on the side away from the connecting pipe 2. The retaining groove 22 also penetrates the upper surface of the horizontal support plate. A retaining rod 21 is fixed to the side wall of the U-shaped cover 6. The retaining rod 21 and the retaining groove 22 are matched in shape, size and position. A threaded groove 23 is opened on the surface of the horizontal support plate on the side away from the vertical plate. The threaded groove 23 penetrates the retaining groove 22 into the horizontal plate. The threaded groove 23 also penetrates the retaining rod 21. A threaded rod 24 is threadedly inserted into the threaded groove 23.
[0045] Specifically, when the device does not require light shielding, the bottom cover 11 should first be secured so that it does not affect the measurement of the device or the sliding of the U-shaped cover 6. Then, the L-shaped baffle 20 should be rotated and moved away so that it does not affect the upward sliding of the U-shaped cover 6. Next, the bottom cover 11 should be used as a handle to move the U-shaped cover 6 upward. After it is in place, the L-shaped baffle 20 should be rotated back to its original position, the threaded rod 24 should be unscrewed, the bottom cover 11 should be loosened, and the stop rod 21 on the U-shaped cover 6 should be inserted into the stop groove 22. Then, the threaded rod 24 should be returned to its original position and tightened, and the U-shaped cover 6 will no longer be able to move up and down.
[0046] like Figure 1 and Figure 2 As shown, the upper surfaces of the four corners of the top cover 7 are all threaded with second fastening bolts 18. The second fastening bolts 18 penetrate the top cover 7 and extend into the frame of the U-shaped cover 6 for bolt fastening.
[0047] Specifically, the top cover 7 and the U-shaped cover 6 can be detached by the second fastening bolt 18. After the top cover 7 is separated from the U-shaped cover 6, the U-shaped cover 6 can slide down for maintenance or inspection.
[0048] like Figure 6 As shown, the lower surface of the bottom cover 11 is threaded with a first fastening bolt 17, which passes through the bottom cover 11 and extends into the cleaning part 12 for bolt fastening.
[0049] Specifically, the cleaning component 12 and the bottom cover 11 can be detached by the first fastening bolt 17. After the locking block 15 is turned out of the slot 16, the bottom cover 11 can be quickly pulled out. Then, the first fastening bolt 17 can be unscrewed to remove the cleaning component 12 for maintenance or inspection.
[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
