Description

Technical Field

[0001] This utility model relates to the field of optical inspection technology, specifically to an optical component inspection fixture. Background Technology

[0002] Optical components are the basic building blocks of optical systems, typically used for imaging, beam splitting, image transmission, filtering, and other functions. Common optical components include lenses, prisms, mirrors, reticles, filters, and gratings. Optical components are widely used in various optical instruments. To ensure the quality and performance of components, effective testing is required. Currently, there are various testing fixtures available on the market for optical components, but some shortcomings still exist.

[0003] Existing optical component testing fixtures often suffer from inaccurate results due to component displacement during testing. For example, Chinese Utility Model Patent CN216523821U discloses an optical component testing fixture comprising a support and a sling. The two free ends of the sling are mounted on the support, and the sling includes a support portion that hangs naturally to support the optical component. The support portion is in at least line contact with the optical component. This invention utilizes line contact to disperse the reaction force exerted by the fixture on the optical component, thereby further reducing and uniformizing the deformation of the optical component. This overcomes the defect of using V-groove or similar mounting brackets, where the optical component deforms at the contact point with the bracket due to its own weight, affecting the surface shape (microscopic surface shape) of most areas near the contact point and leading to severe distortion of the testing results. However, this device, which uses slings to support the components, can lead to unstable support. In addition, this device can only test a single optical element at a time, which greatly reduces the testing efficiency. Furthermore, the detector and the device are usually connected by welding, which makes it difficult to disassemble and replace if damaged. Therefore, we propose an optical element testing fixture to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide an optical component inspection fixture to solve the problems of the existing optical component inspection fixtures mentioned in the background art, which have the following problems: the components may move during the inspection, which will lead to inaccurate inspection results; at the same time, only one component can be inspected at a time, which will greatly reduce the inspection efficiency; in addition, the detector and the device are welded together, which makes it difficult to quickly replace them once damaged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an optical element inspection fixture, comprising:

[0006] A support base, with a rubber plate fixedly installed below it;

[0007] Also includes:

[0008] A multi-element detection mechanism is provided above the support base. The multi-element detection mechanism includes a rotating disk, a motor, a connecting rod, and bolts. The rotating disk is rotatably provided above the support base, and a motor is provided above the center of the rotating disk. A connecting rod is installed at equal angles on the outer side of the rotating disk, and a bolt is provided inside the connecting rod.

[0009] A limiting mechanism is provided at equal angles above the support base. The limiting mechanism includes a support frame, a moving block, a limiting plate, a fixed rod, a rotating frame, a fixed column, a connecting bracket, an electric telescopic rod, and a sliding block. The support frame is provided at equal angles above the support base and is located inside the connecting rod. The support frame and the connecting rod are fixedly connected by bolts. A moving block is slidably provided inside the upper part of the support frame.

[0010] Preferably, a limiting plate is fixedly connected inside the movable block, and a fixing rod is connected to the outside of the movable block, with the outer side of the fixing rod rotatably connected to the upper interior of the rotating frame.

[0011] Preferably, the middle part of the rotating frame is rotatably connected to the outer side of the support frame, and a connecting bracket is rotatably connected to the inner side of the middle part of the rotating frame.

[0012] Preferably, a sliding block is rotatably connected above the connecting bracket, and the sliding block is slidably disposed on the outside of the fixed column, and the fixed column is fixedly installed in the middle of the support frame.

[0013] Preferably, an electric telescopic rod is provided on the lower inner side of the rotating frame.

[0014] Preferably, an anti-slip mat is installed at an equal angle below the rubber sheet, and the anti-slip mat is placed directly on the ground.

[0015] Preferably, a fixing frame is fixedly installed on the left side of the support base, and a hydraulic cylinder is fixedly installed above the fixing frame, and a support plate is installed at the output end of the hydraulic cylinder.

[0016] Preferably, a fixing plate is slidably disposed inside the support plate, and a threaded rod is tightly fitted to the outside of the fixing plate, and the threaded rod is threadedly connected to the support plate, and a detector is tightly fitted inside the fixing plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the optical element detection fixture, by setting a limiting mechanism, can fix the position of the optical element, ensuring that the element will not move during the detection process, thereby greatly improving the detection accuracy. At the same time, it is equipped with a multi-element detection mechanism, which can detect multiple elements at one time, greatly improving the detection efficiency. In addition, it is equipped with a disassembly mechanism, which facilitates the disassembly, replacement or maintenance of the detector.

[0018] 1. It is equipped with a support base, a rotating disk, a motor, and a connecting rod. The rotating disk is installed above the middle of the support base, and the motor is connected to the middle of the support base. The motor is located above the middle of the rotating disk. In addition, the connecting rod is set at the same angle on the outer side of the rotating disk. The limiting mechanism is fixed inside the connecting rod by bolts. That is, when the motor is turned on, the rotating disk can rotate, which drives the limiting mechanism to rotate together. This allows for the simultaneous detection of optical elements limited by multiple limiting mechanisms.

[0019] 2. It is equipped with a support base, a rubber plate and an anti-slip pad. The rubber plate installed under the support base can reduce the vibration of the device during operation due to its own characteristics. At the same time, the anti-slip pad is installed at the same angle under the rubber plate. The anti-slip pad is in direct contact with the ground to prevent the device from shifting during operation.

[0020] 3. The device is equipped with a support frame, a movable block, a limiting plate, and a fixing rod. By placing the component above the center of the support frame, the electric telescopic rod is opened. Since the outer side of the electric telescopic rod is connected to the rotating frame, the rotating frame and the support frame will rotate. Since the inner side of the center of the rotating frame is connected to the connecting bracket, and the connecting bracket is connected to the sliding block, when the rotating frame rotates outward, the connecting bracket pulls the sliding block to slide downward on the outside of the fixing column. In addition, since the upper part of the rotating frame is connected to the fixing rod, the fixing rod can be pushed to move inward. When the fixing rod moves inward, it pushes the movable block installed inside to slide inward. The limiting plate installed inside the movable block can clamp and fix the component placed above the center of the support frame.

[0021] 4. It is equipped with a fixed frame and a hydraulic cylinder. The fixed frame is fixedly installed on the left side of the support base, and the hydraulic cylinder is fixedly installed on the top of the fixed frame. The output end of the hydraulic cylinder is equipped with a support plate, and the detector is set on the lower inner side of the support plate. That is, the fixed frame can support the detector, and when the hydraulic cylinder is opened, the output end of the hydraulic cylinder can push the detector to move.

[0022] 5. It is equipped with a support plate, a threaded rod, a fixing plate and a detector. The fixing plate is tightly attached to the outside of the detector, and the threaded rod is tightly attached to the outside of the fixing plate. The threaded rod is threadedly connected to the support plate. That is, by simply rotating the threaded rod to disengage it from the support plate, the fixing plate can be slid outward, which can also separate the fixing plate from the detector. In this way, the detector can be removed for replacement or maintenance. Attached Figure Description

[0030] 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.

[0031] Please see Figures 1-6 This utility model provides a technical solution:

[0032] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: an optical component inspection fixture, comprising a support base 1; a limiting mechanism, equally spaced above the support base 1, which limits the component and ensures that the component does not shift position during inspection; a multi-component inspection mechanism, positioned above the support base 1, which can inspect multiple components simultaneously, thereby greatly improving the efficiency of component inspection; and a disassembly mechanism, positioned below the hydraulic cylinder 17, which facilitates the disassembly and replacement of the detector 21. If the detector 21 malfunctions, it can be easily disassembled, replaced, or repaired without affecting the operation of the device. First, the optical component is placed above the support frame 6, and then the electric telescopic mechanism is activated. The electric telescopic rod 13 is connected to the lower part of the rotating frame 10 on its outer side. The rotating frame 10 is rotatably connected to the support frame 6. When the electric telescopic rod 13 is activated, the lower part of the rotating frame 10 will rotate outward. The inner side of the middle part of the rotating frame 10 is connected to the connecting bracket 12. The upper part of the connecting bracket 12 is connected to the sliding block 22. When the rotating frame 10 rotates, the connecting bracket 12 pulls the sliding block 22 to slide downward on the outside of the fixed column 11. At the same time, the upper part of the rotating frame 10 is rotatably connected to the fixed rod 9. Therefore, when the lower part of the rotating frame 10 rotates outward and the sliding block 22 moves downward on the outside of the fixed column 11, the upper part of the rotating frame 10 will push the fixed rod 9 inward. The moving block 7 is connected to the inner side of the fixed rod 9, so the moving block 7 will move inward above the support frame 6. The moving block 7 is equipped with a limiting plate 8, which limits the components placed above the middle of the support frame 6. In addition, the connecting rod 4 is fixedly connected to the outer side of the support frame 6 by bolts 5. The connecting rod 4 is fixed at an equal angle to the outer side of the rotating disk 2. Since the rotating disk 2 is located above the middle of the support base 1, and the motor 3 is set on the upper side of the middle of the rotating disk 2, turning on the motor 3 will make the rotating disk 2 rotate. A rubber plate 14 is installed under the support base 1 to reduce vibration during operation. Anti-slip pads 15 are installed at an equal angle under the rubber plate 14 to prevent the device from shifting during operation. When the device rotates, a fixing frame 16 is installed on the left side of the support base 1, and a hydraulic cylinder 17 is installed above the fixing frame 16. A support plate 18 is installed at the output end of the hydraulic cylinder 17, and a detector 21 is installed on the inner side of the support plate 18. When the hydraulic cylinder 17 is opened, the output end of the hydraulic cylinder 17 can push the detector 21 to move downward to detect the rotating clamped component. In addition, the outer side of the detector 21 is tightly attached to the fixing plate 20, and the outer side of the fixing plate 20 is tightly attached to the threaded rod 19 for limiting. If the detector 21 malfunctions, the threaded rod 19, which is threaded to the support plate 18, is unscrewed and pulled out, which will loosen the fixing plate 20. The fixing plate 20 can then be moved outward to remove the detector 21 for repair or replacement.

[0033] Existing testing fixtures, when used for component testing, can lead to inaccurate test results due to component movement. Therefore, this embodiment addresses this issue by employing the following technical solution: Figure 3 , Figure 5 and Figure 6 As shown, the limiting mechanism includes a support frame 6 located inside the connecting rod 4. When the component is placed above the middle of the support frame 6, the electric telescopic rod 13 is opened. Since the outer side of the electric telescopic rod 13 is connected to the rotating frame 10, the rotating frame 10 and the support frame 6 will rotate. Since the inner side of the middle of the rotating frame 10 is connected to the connecting bracket 12, and the connecting bracket 12 is connected to the sliding block 22, when the rotating frame 10 rotates outward from below, the connecting bracket 12 will pull the sliding block 22 to slide downward on the outside of the fixed column 11. In addition, since the upper interior of the rotating frame 10 is connected to the fixed rod 9, the fixed rod 9 can be pushed to move inward. When the fixed rod 9 moves inward, it will push the internally installed moving block 7 to slide inward. The limiting plate 8 installed inside the moving block 7 can clamp and fix the component placed above the middle of the support frame 6.

[0034] Example 2: Existing testing fixtures can only test a single component at a time, which greatly reduces testing efficiency. Therefore, this example uses the following technical solution, such as... Figure 1 , Figure 2 and Figure 3 As shown, the multi-element detection mechanism includes a rotating disk 2 located above the center of the support base 1. A motor 3 is connected to the center of the support base 1. The motor 3 is located above the center of the rotating disk 2. In addition, a connecting rod 4 is set at an equal angle on the outer side of the rotating disk 2. A limiting mechanism is fixedly installed inside the connecting rod 4 by bolts 5. That is, when the motor 3 is turned on, the rotating disk 2 can rotate, which drives the limiting mechanism to rotate together. This allows for the detection of optical elements limited by multiple limiting mechanisms at one time.

[0035] Example 3: Existing detection fixtures, where the detector 21 is welded to the device, suffer from difficulties in rapid replacement in case of damage. Therefore, this example addresses these issues through the following technical solution: Figure 1 , Figure 2 and Figure 4As shown, the easy-to-disassemble mechanism includes a support plate 18 disposed at the output end of the hydraulic cylinder 17. A detector 21 is disposed inside the support plate 18. The outer side of the detector 21 is tightly fitted with a fixing plate 20, and the outer side of the fixing plate 20 is tightly fitted with a threaded rod 19. The threaded rod 19 is threadedly connected to the support plate 18. That is, by simply rotating the threaded rod 19 to disengage it from the support plate 18, the fixing plate 20 can be slid outward, which can also separate the fixing plate 20 from the detector 21. In this way, the detector 21 can be removed for replacement or maintenance.
