[0002] As a core component of optical systems, optical glass's surface precision, geometric dimensions, and optical properties (such as refractive index and uniformity) directly affect the imaging quality and reliability of optical instruments. In the production and testing of optical glass, high-precision fixing and flatness calibration are key prerequisites for ensuring the accuracy of test results.

[0003] Traditional optical glass testing devices rely on mechanical clamps for rigid compression and fixation during use, which can easily damage the devices. The clamping method is relatively cumbersome and it is difficult to adapt to devices of different specifications. Based on this, an improved optical glass device testing device is proposed. Utility Model Content

[0004] In view of the problems of existing easily damaged devices, relatively cumbersome clamping methods, and difficulty in adapting to devices of different specifications, this utility model is proposed.

[0005] To solve the above technical problems, this utility model provides the following technical solution: an optical glass device testing device, including a worktable, an adsorption box arranged above the worktable, an adsorption groove opened at the bottom of the adsorption box, a plurality of air inlets opened on the top wall of the adsorption groove, a plurality of conical rubber suction cups fixedly installed on the inner wall of the adsorption box, the interior of the conical rubber suction cups communicating with the interior of the air inlets, a conical tube fixedly sleeved on the bottom wall of the air inlet, an exhaust pipe fixedly sleeved at the bottom end of the conical tube, an exhaust fan connected to one end of the exhaust pipe, and the top end of the exhaust fan fixedly connected to the bottom end of the worktable; the adsorption box includes a clamping mechanism.

[0006] An adjustment box is fixedly connected to the front side of the adsorption box. Sliding rods are slidably connected inside both ends of the adjustment box. A push block is slidably connected to the middle of the adjustment box. Two linkage rods are movably connected to one end of the push block. One end of the two linkage rods is movably connected to one end of the sliding rod. An adjustment plate is fixedly connected to the other end of the sliding rod through a first connecting block. Several adaptive locking rods are slidably connected inside the adjustment plate. A second spring is sleeved on the surface of the adaptive locking rod. The two ends of the second spring are respectively connected to the side wall of the adjustment plate and the baffle at one end of the adaptive locking rod.

[0007] As a preferred embodiment, the adjustment box has a sliding groove inside, a sliding ring is fixedly sleeved on the surface of the sliding rod, the sliding ring is slidably connected to the inner wall of the sliding groove, and a first spring is sleeved on the surface of the sliding rod, with the two ends of the first spring connected to one side of the sliding ring and the inner wall of the sliding groove, respectively.

[0008] As a preferred embodiment, one end of the adjusting plate is fixedly connected to a guide rod via a second connecting block, the guide rod is slidably connected inside the guide plate, and one side of the guide plate is fixedly connected to the rear side of the adsorption box.

[0009] As a preferred embodiment, the workbench is equipped with three planar fine-tuning mechanisms, which are distributed at equal angles with the center of the bottom of the adsorption box as the reference.

[0010] As a preferred embodiment, a handwheel is provided below the worktable, and a lead screw is fixedly sleeved inside the handwheel, with the lead screw threaded into the inside of the worktable.

[0011] As a preferred embodiment, an adjusting ball is fixedly connected to the top of the lead screw, the adjusting ball is movably connected to the internal groove of the adjusting seat, and the top of the adjusting seat is fixedly connected to the bottom of the adsorption box.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. This utility model uses a conical rubber suction cup to adhere to the surface of the device under negative pressure, and uses atmospheric pressure to achieve fixation without direct contact with the device surface, thus avoiding scratches. With the adaptive clamping rod and a second spring, the position can be automatically adjusted according to the edge contour of the device, which can be adapted to devices of different specifications. By combining negative pressure adsorption and elastic clamping, the device can be quickly clamped. The adsorption force provides basic positioning, and the clamping mechanism provides auxiliary fixation from the edge, providing double protection to prevent the device from shifting. While ensuring the fixation accuracy of the device, it significantly improves the ease of operation and the versatility of the equipment.

[0014] 2. This utility model uses a handwheel to manually rotate, which drives the lead screw to move axially to rise or fall. During the rise and fall of the lead screw, the adjusting ball is also raised or lowered. While the adjusting ball is rising or falling, it can rotate freely in the slot of the adjusting seat, allowing the adsorption box to tilt within a small angle range. This achieves dual fine adjustment of the height and angle of the adsorption box. Through the coordinated adjustment of three planar fine adjustment mechanisms, the optical glass device is ensured to be on the same horizontal plane. Attached Figure Description

Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1-4 This is the first embodiment of the present invention, which provides an optical glass device testing device, including a workbench 1, an adsorption box 2 above the workbench 1, an adsorption groove 21 at the bottom of the adsorption box 2, a plurality of air inlets 22 on the top wall of the adsorption groove 21, a plurality of conical rubber suction cups 23 fixedly installed on the inner wall of the adsorption box 2, the interior of the conical rubber suction cups 23 being connected to the interior of the air inlets 22, a conical tube 24 fixedly sleeved on the bottom wall of the air inlet 22, an exhaust pipe 3 fixedly sleeved on the bottom end of the conical tube 24, an exhaust fan 31 connected to one end of the exhaust pipe 3, and the top end of the exhaust fan 31 fixedly connected to the bottom end of the workbench 1. The adsorption box 2 includes a clamping mechanism 4.

[0023] An adjustment box 41 is fixedly connected to the front side of the adsorption box 2. Slide rods 44 are slidably connected to both ends of the adjustment box 41. A push block 42 is slidably connected to the middle of the adjustment box 41. Two linkage rods 43 are movably connected to one end of the push block 42. One end of the two linkage rods 43 is movably connected to one end of the slide rod 44. An adjustment plate 49 is fixedly connected to the other end of the slide rod 44 through a first connecting block 48. Several adaptive locking rods 410 are slidably connected inside the adjustment plate 49. A second spring 411 is sleeved on the surface of the adaptive locking rod 410. The two ends of the second spring 411 are respectively connected to the side wall of the adjustment plate 49 and the baffle at one end of the adaptive locking rod 410.

[0024] The adjustment box 41 has a sliding groove 47 inside. A sliding ring 45 is fixedly sleeved on the surface of the sliding rod 44. The sliding ring 45 is slidably connected to the inner wall of the sliding groove 47. A first spring 46 is sleeved on the surface of the sliding rod 44. The two ends of the first spring 46 are respectively connected to one side of the sliding ring 45 and the inner wall of the sliding groove 47.

[0025] One end of the adjusting plate 49 is fixedly connected to a guide rod 413 via a second connecting block 412. The guide rod 413 is slidably connected inside the guide plate 414. One side of the guide plate 414 is fixedly connected to the rear side of the adsorption box 2.

[0026] During use, when it is necessary to fix the optical glass product on the device, first push the push block 42. The push block 42 drives the slide rods 44 on both sides to move outward through the two linkage rods 43, and compresses the first spring 46 through the slip ring 45. The slide rods 44 drive the adjustment plate 49 to move through the first connecting block 48, thereby causing the adaptive clamping rod 410 to leave the adsorption box 2, leaving enough space to place the device.

[0027] Place the device flat inside the adsorption box 2 so that its surface contacts the conical rubber suction cup 23. Turn on the power of the exhaust fan 31. The exhaust fan 31 operates and draws air into the air inlet 22 through the exhaust pipe 3 and the conical pipe 24. The conical rubber suction cup 23 deforms due to the negative pressure and fits tightly against the surface of the device to form a sealed cavity. The air pressure in the adsorption tank 21 drops, and the atmospheric pressure firmly presses the device to the bottom of the adsorption box 2.

[0028] Next, the push block 42 is released, the first spring 46 rebounds, and the slide ring 45 applies a spring force to the slide rod 44 to move it towards the center, so that the adjusting plate 49 returns to its initial clamping posture.

[0029] When the adjustment plate 49 approaches the adsorption box 2, one end of the adaptive lever 410 contacts the edge of the product. If the edge of the device is irregular, the adaptive lever 410 slides along the inside of the adjustment plate 49 after being pressed, stretching the second spring 411 and automatically adapting to the contour of the device. The end of the adaptive lever 410 that contacts the edge of the product is fitted with a rubber sleeve to avoid damage to the product.

[0030] The adjusting plate 49 slides within the guide rod 413 connected by the second connecting block 412, ensuring that the adjusting plate 49 remains horizontal during clamping and avoiding displacement.

[0031] This design uses a conical rubber suction cup 23 to adhere to the surface of the device under negative pressure, using atmospheric pressure to achieve fixation without direct contact with the device surface, thus avoiding scratches. The adaptive clamp 410, in conjunction with the second spring 411, can automatically adjust its position according to the edge contour of the device, making it suitable for devices of different specifications. The combination of negative pressure adsorption and elastic clamping enables quick clamping of the device. The adsorption force provides basic positioning, while the clamping mechanism 4 provides auxiliary fixation from the edge, providing double protection to prevent the device from shifting. While ensuring the device fixation accuracy, it significantly improves the ease of operation and the versatility of the equipment.

[0032] Reference Figures 1-4This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the workbench 1 is provided with three planar fine adjustment mechanisms 5. The three planar fine adjustment mechanisms 5 are distributed at equal angles with the center of the bottom end of the adsorption box 2 as the reference.

[0033] A handwheel 51 is provided below the workbench 1. A lead screw 52 is fixedly connected inside the handwheel 51. The lead screw 52 is threadedly connected inside the workbench 1.

[0034] An adjusting ball 53 is fixedly connected to the top of the lead screw 52. The adjusting ball 53 is movably connected to the internal groove of the adjusting seat 54. The top of the adjusting seat 54 is fixedly connected to the bottom of the adsorption box 2.

[0035] During use, the three planar fine-tuning mechanisms 5 are distributed at 120° equidistant angles with the center of the bottom end of the adsorption box 2 as the reference, forming a stable planar adjustment system through three-point support;

[0036] When it is necessary to ensure that the optical glass products are on the same plane, manually rotate the handwheel 51 to drive the lead screw 52 to move axially to rise or fall. During the raising and lowering process of the lead screw 52, ​​the adjusting ball 53 is driven to rise and fall. While the adjusting ball 53 is rising and falling, it can rotate freely in the slot of the adjusting seat 54, allowing the adsorption box 2 to tilt within a small angle range, thereby realizing dual fine adjustment of the height and angle of the adsorption box 2. Through the coordinated adjustment of the three planar fine adjustment mechanisms 5, the optical glass products are thus ensured to be on the same horizontal plane.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
