Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, and more specifically to an optical lens adjusting device. Background Art

[0002] Optical lenses are transparent materials with one or more curved surfaces made of optical materials such as glass or resin. After polishing, they are often assembled with eyeglass frames to form glasses, which are used to correct the user's vision and obtain a clear field of vision. During the processing of optical lenses, the optical lenses need to be clamped. At present, the traditional optical lens clamping device includes a mounting ring, a plurality of bolts threadedly connected to the mounting ring and used to respectively tighten the outer wall of the smooth lens. When processing the lens, it involves the need to observe or process the part of the optical lens, and the traditional optical lens clamping device cannot adjust the angle of the lens after clamping, so it cannot adapt to a variety of processing conditions. In addition, this clamping method easily causes wear on the outer surface of the lens, which is inconvenient to install the lens and process or polish the edge of the lens.

[0003] In view of the above problems, the conventional optical lens clamping device cannot adjust the angle of the lens after clamping, cannot adapt to a variety of processing conditions, and the clamping method easily causes wear on the outer surface of the lens, is inconvenient to install the lens, and is inconvenient to process or grind the edge of the lens. After a lot of searching, an optical lens adjustment device with patent number CN217932228U was found, which includes a bottom plate, a fixing block is fixedly connected to the front and rear sides of the upper surface of the bottom plate on the left side, a support rod is fixedly connected between the side walls of the fixing block, and the outer surface of the support rod is rotatably connected to the fixing block on both sides. A sleeve, one side of the sleeve is fixedly connected to a workbench, grooves are provided on both sides of the upper surface of the bottom plate away from the fixed block, the inner bottom wall of the groove is fixedly connected to a first connecting ear seat, the inner wall of the first connecting ear seat is connected to a first electric telescopic rod through a rotating shaft, a side of the lower surface of the workbench close to the first connecting ear seat is fixedly connected to a second connecting ear seat, one end of the inner rod of the first electric telescopic rod is connected to the inner wall of the second connecting ear seat through a rotating shaft, the workbench is movably connected to the bottom plate through the sleeve, the support rod, the first connecting ear seat, the second connecting ear seat, and the first electric telescopic rod; however, the technical solution provided by the patent still has the following problems:

[0004] (1) The adjustment device cannot adjust the size of the lens clamping device and can only clamp and fix optical lenses of a single specification, and cannot meet the adjustment and processing requirements of optical lenses of multiple specifications;

[0005] (2) The adjustment device can only adjust the tilt angle of the lens surface, but cannot flip the mirror surface. When processing and polishing the lens, the lens needs to be disassembled and reassembled to process the other side, which reduces work efficiency. Utility Model Content

[0024] The following will be combined with the attached embodiment of the present utility model Figure 1-Figure 4 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0025] See also Figure 1-4 In an embodiment of the utility model, an optical lens adjustment device includes: two mounting frames 1, the two mounting frames 1 are connected by a mounting rod 2, a fixing block 3 is fixedly installed on the top of one of the mounting frames 1, a rotating rod 11 is installed between the side walls of the fixing block 3, a workbench 4 is installed on the rotating rod 11, and two limiters 5 are arranged in the workbench 4, a sliding block 6 is installed on the mounting rod 2, a supporting rod 7 is hinged on the top of the sliding block 6, and the other end of the supporting rod 7 is hinged to the bottom of the workbench 4, and a driving device is arranged at the rear end of the sliding block 6.

[0026] In the embodiment of the utility model, the driving device includes a connecting rod 9, a rack 8 and a driving gear meshing with the rack 8. The connecting rod 9 is fixedly installed at the rear end of the slider 6, the rack 8 is fixedly installed in the middle of the connecting rod 9, and the rear part of the rack 8 is through-installed in the middle of another mounting frame 1 located at the rear end of the device. At the same time, the driving gear is arranged in the mounting frame 1 and meshing with the rack 8. When the driving gear rotates, the rack 8 is driven to move back and forth, and at the same time, the rack 8 drives the connecting rod 9 to move. The connecting rod 9 enables the slider 6 fixedly installed at the front end of the connecting rod 9 to maintain synchronous sliding. In the comparative document, the workbench is adjusted by a telescopic rod, and hinges are connected at both ends of the telescopic rod. During the operation of the telescopic rod, due to the movement of the telescopic rod, it is very easy to cause the rotation directions of the hinges on both sides to be inconsistent, making the adjustment angle of the workbench not precise enough. However, in the utility model, the synchronous movement of the support rods 7 on both sides can be ensured, so that the angle adjustment of the workbench 4 is more precise.

[0027] In the embodiment of the utility model, a circular groove running through from top to bottom is opened in the middle of the workbench 4, and mounting grooves are opened at the front and rear ends of the circular groove. The limiter 5 is fixedly installed in the mounting groove. The two limiters 5 are installed at relative positions. The horizontal supporting force generated on the optical lens is in a straight line, and the directions of the forces are relative, so the optical lens can be fixed more stably.

[0028] In the embodiment of the utility model, the limiter 5 includes an electric telescopic rod 501, a rotating shaft 502 and a limit block 503. The tail end of the electric telescopic rod 501 is fixedly installed in the installation groove opened on the workbench 4. Through the telescopic movement of the electric telescopic rod 501, the distance between the two limiters 5 in relative positions can be adjusted to achieve the purpose of clamping and fixing optical lenses of different sizes. The rotating shaft 502 is installed at the other end of the electric telescopic rod 501. After the optical lens is fixed on the limiter 5, the two rotating shafts 502 are rotated clockwise or counterclockwise at the same time, so as to realize automatic flipping of the optical lens without manual reassembly. The limit block 503 is fixedly installed on the rotating shaft 502.

[0029] In the embodiment of the utility model, the limit block 503 is made of soft rubber material, so that a sufficiently large friction force can be generated between the limit block 503 and the optical lens to prevent the optical lens from sliding on the limiter 5. At the same time, the soft limit block 503 can also prevent the limit block 503 from colliding with the optical lens during the installation and disassembly process, thereby causing damage to the lens. The limit block 503 is generally arranged in an arc shape, and at the same time, an arc-shaped supporting protrusion is formed at the bottom of the limit block 503 toward the center of the workbench 4, and an arc-shaped elastic metal part 504 is arranged inside the limit block 503, so that the soft limit block 503 can be deformed according to the shape of the lens when the lens is squeezed and fixed, so as to adapt to the fixing work requirements of optical lenses of different specifications.

[0030] In the embodiment of the utility model, a rectangular slide groove is opened at the top rear portion of the mounting rod 2, and a slider 6 is slidably installed in the slide groove. When adjusting the angle of the optical lens, the slider 6 can slide in the rectangular slide groove, driving the support rod 7 to rotate, and the rotation of the support rod 7 drives the workbench 4 to rotate, so as to achieve the purpose of adjusting the angle of the optical lens.

[0031] In the embodiment of the utility model, the mounting frame 1 is generally in an "N" shape, and a suction cup 10 is installed at the bottom end of the supporting foot at the bottom of the mounting frame 1. The suction cup 10 can fix the adjustment device on the processing workbench so that the adjustment device will not move during the processing and affect the processing work.

[0032] Working principle: first, the distance between the two limit blocks 503 is roughly adjusted through the electric telescopic rod 501 in the limiter 5, and then the optical lens is placed between the two limiters 5, and then the adjustment is continued to make the limiter 5 clamp the optical lens; when adjusting the angle of the optical lens, the drive motor is started to drive the driving gear to rotate, and then drive the rack 8 to move back and forth, and at the same time the rack 8 drives the connecting rod 9 to move, and the connecting rod 9 makes the slider 6 fixedly installed on the front end of the connecting rod 9 keep sliding synchronously and drive the support rod 7 to rotate, and the rotation of the support rod 7 drives the workbench 4 to rotate, so as to achieve the purpose of adjusting the angle of the optical lens; when the optical lens needs to be flipped, the two electric telescopic rods 501 keep their original positions to ensure that the limit blocks 503 can still tighten the lens, and then the two rotating shafts 502 are rotated clockwise or counterclockwise at the same time to realize the automatic flipping of the optical lens.
