Description

Technical Field

[0001] The utility model belongs to the technical field of optical lens detection, in particular to an optical lens thickness detection device. Background Art

[0002] Optical lenses are components made of transparent materials used to control and regulate light, with specific optical properties. They are commonly used in a variety of optical instruments and devices, such as glasses, cameras, microscopes, and telescopes. The design and manufacturing process of optical lenses requires a high degree of precision to ensure that their optical performance meets the expected standards.

[0003] A search revealed the patent number CN221037199U, which describes a device for detecting the thickness of an optical lens. The device features a clamping plate that can clamp and secure both sides of the optical lens, ensuring stability during testing. When the detection plate contacts the top of the optical lens, the corresponding thickness value can be measured by observing the intersection of the pointer and the scale. This solves the problem of increased maintenance and repair costs and potential downtime if the laser pen is damaged and needs to be repaired or replaced, thereby improving work efficiency. This device has the following problems: when the detection plate falls and contacts the optical lens, it can easily push the optical lens downward, resulting in measurement errors. Furthermore, the clamping plate cannot clamp circular optical lenses, making it less suitable for use.

[0004] The purpose of the utility model is to provide an optical lens thickness detection device to solve the problems raised in the background technology. Utility Model Content

[0005] The purpose of the utility model is to provide an optical lens thickness detection device to solve the problems raised in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an optical lens thickness detection device, comprising a workbench, a fixing assembly for fixing circular optical lenses of different diameters is provided on the top of the workbench, and a measuring assembly for detecting the thickness of the optical lens is provided on the outside of the fixing assembly;

[0007] The fixing assembly includes a mounting box fixedly mounted on the top of the workbench, a mounting plate fixedly mounted on the top of the mounting box, a fixing plate fixedly mounted inside the mounting plate, a plurality of sliding grooves evenly provided on the fixing plate, a sliding rod slidingly connected in a single sliding groove, the sliding rod being slidably connected to the mounting plate, a first gear being rotatably connected to the top of the fixing plate, a limiting column fixedly mounted on the top of the sliding rod, a limiting groove penetrating therethrough for limiting the movement trajectory of the limiting column being provided on the first gear, and the first gear being meshed with a second gear.

[0008] Furthermore, the second gear is rotatably connected to the top of the fixed plate, and a rotating column is connected to the axis of the bottom of the second gear. The rotating column passes through the mounting box and the end is connected to the first bevel gear.

[0009] Furthermore, the first bevel gear is meshedly connected with the second bevel gear, and the axis of the second bevel gear is connected with a rotating handle, and the rotating handle passes through the installation box and is arranged on one side of the installation box.

[0010] Furthermore, a clamping plate is fixedly installed on the top of the end of a single sliding rod, and the clamping plate is arc-shaped.

[0011] Furthermore, the measuring assembly includes a mounting plate symmetrically fixedly mounted on the top of the workbench, a single mounting plate is provided with a cavity on one side, a screw is provided in the cavity, and a sliding block is threadedly connected to the outer side of the screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model sets a fixed component, and by rotating the rotating handle, the rotating handle drives the second bevel gear to rotate, and then drives the first bevel gear to rotate, thereby driving the second gear to rotate, and then the first gear rotates, and then the clamping plate is closed. This has the advantage of providing uniform support for the optical lens, reducing displacement and vibration during operation, ensuring the stability of measurement or processing, and can be designed to adapt to optical lenses of various diameters, increasing the versatility of the equipment, and facilitating use in different situations. At the same time, the optical lens will not fall during measurement, and the screw is driven by the motor to rotate, and then the sliding block drives the contact plate to move. The position of the contact plate on the scale plate is the thickness of the optical lens. This has the advantage of being relatively simple and convenient to measure, and the result is accurate.

The purpose of arranging the arc-shaped splint 15 here is to better fit the side of the optical lens so that the fixing effect is better, the sliding rod 14 is slidably connected to the mounting disk 10, and the top of the fixed disk 17 is rotatably connected to the first gear 11, and a limiting column 13 is fixedly installed on the top of the sliding rod 14, a limiting groove 12 is provided on the first gear 11 for limiting the movement trajectory of the limiting column 13, and the first gear 11 is meshed with the second gear 19.

[0027] The second gear 19 is rotatably connected to the top of the fixed plate 17, and a rotating column 20 is connected to the axis of the bottom of the second gear 19. The rotating column 20 passes through the mounting box 9 and is connected to the first bevel gear 21 at the end. The first bevel gear 21 is meshed with the second bevel gear 22. The second bevel gear 22 is connected to the rotating handle 16 at the axis. The rotating handle 16 passes through the mounting box 9 and is arranged on one side of the mounting box 9. The rotating handle 16 is used to control the rotation of the second bevel gear 22.

[0028] The measuring assembly includes a mounting plate 2 symmetrically fixedly mounted on the top of the workbench 1. A cavity is opened on one side of a single mounting plate 2, and a screw 4 is arranged in the cavity. A sliding block 5 is threadedly connected to the outer side of the screw 4. A sliding plate 6 is connected between the two sliding blocks 5. A contact plate 7 is fixedly mounted on one side of the sliding plate 6.
