Description

Technical Field

[0001] The utility model relates to the technical field of lens processing, in particular to an adjustable optical lens processing tool. Background Art

[0002] Optical lenses are lenses used in optical instruments or equipment. Their main function is to refract light so that it propagates along a specific path. These lenses are usually made of glass or plastic and have specific optical properties, such as focal length, refractive index, dispersion, etc. With the advancement of science and technology, the design and manufacturing technology of optical lenses are also constantly developing, such as using new materials, processes and designs to improve the performance of lenses, reduce size and weight, etc.

[0003] After searching, a Chinese patent with application number CN202120198572.0 discloses an optical lens processing tooling. During polishing, the lens needs to be lifted, turned and flipped to adapt to the polishing process of different equipment. Therefore, the lens can be lifted and turned as well as rotated to ensure the quality of polishing.

[0004] When the optical lens is polished as mentioned above, it can only be lifted, lowered and flipped, and is relatively weak under the clamping effect of the optical lens. When polishing the edge of the optical lens, because the two sides of the optical lens are usually slightly convex, it is not convenient to clamp multiple points on both sides of the lens when clamping the optical lens, and the sizes of optical lenses are usually different. When polishing, it is not convenient to adjust the points clamped by the clamping tool according to the size of the optical lens. If the clamping tool is less compatible with the optical lens, it is easy to cause slippage during clamping, resulting in reduced clamping force, thereby reducing the polishing quality.

[0037] Working principle: When clamping the optical lens before grinding, first adjust the position of the push rod 8 and the rotating block 9 according to the size of the optical lens, press the blocks 12 on both sides to squeeze the blocks 12 on both sides to the middle spring 11, so that the spring 11 is squeezed to generate elastic force, so that the two blocks 12 are retracted into the columnar groove 10, and then pull the push rod 8 to slide inside the outer tube 6 to adjust the length of the push rod 8 extending out of the outer tube 6, so as to drive the rotating block 9 to adjust the position. After adjustment, the spring 11 presses the blocks 12 on both sides. Under the pushing action of the clamping block 12, it is convenient for the clamping block 12 to be clamped into the corresponding clamping groove 7, so as to limit the position of the push rod 8, so as to facilitate the adjustment of the clamping point to be clamped, and then the optical lens is vertically placed in the middle of the two rotating plates 5, and then the handle 28 is rotated, and the handle 28 drives the bidirectional screw rod 3 to rotate, so that when the bidirectional screw rod 3 rotates, the moving frames 4 on both sides are driven to approach each other, so as to facilitate the two rotating plates 5 to approach each other, and under the action of the rotating plates 5 approaching, the multiple push rods 8 on both sides are driven to approach each other, so as to adjust the optical lens. At the same time, under the action of the rotating block 9, it is convenient to adjust the clamping angle according to the inclination of the clamped surface of the optical lens, so as to facilitate a closer fit with the optical lens, and then the hydraulic cylinder 13 is turned on, and the extension and contraction of the hydraulic cylinder 13 drives the connecting rod 14 to move, so as to facilitate the extension and contraction of the rack 16, and the engagement of the gear 15 with the rack 16 is conducive to driving the gear 15 to rotate, so that the gear 15 drives the right end rotating plate 5 to rotate, and it is convenient to drive the clamped optical lens to rotate, thereby improving the uniformity of grinding. When dust is generated during grinding, the fan 18 is turned on. With the action of the fan 18 sucking in air through the air inlet plate 20, the wind is transmitted through the air supply pipe 19 and then blown toward the optical lens being ground. With the action of the front baffle 22 and the side baffle 21, the debris is blown to the front end of the processing table 1 and then blown into the interior of the dirt receiving box 23. When it is necessary to clean the dust inside the dirt receiving box 23, the push plate 25 inside the sliding groove 24 is slidable, so that the push plate 25 pushes the dust into the discharge pipe at the rear end of the dirt receiving box 23, thereby facilitating the collection and cleaning of the dust.
