Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, specifically a clamping tooling for processing concave and convex lenses. Background Technology

[0002] When machining concave and convex lenses, clamping fixtures are required. These fixtures must ensure stable clamping of the lens while avoiding damage to the lens surface and guaranteeing machining accuracy. This includes mechanical positioning clamping fixtures, which employ mechanical positioning structures such as locating pins and locating grooves to precisely position the lens. The lens is then fixed to the fixture using bolts, nuts, or other mechanical clamping devices. These fixtures offer high positioning accuracy, ensuring the lens's position is precise during machining.

[0003] The existing clamping fixtures for processing concave and convex lenses still have the following problems when in use: mechanical positioning clamping fixtures are cumbersome to use, and the clamping process requires precise adjustment of the positioning and clamping devices, which results in long operation time, low efficiency, and is not suitable for small-batch, multi-variety production. In addition, if the clamping force is unevenly distributed or too large, it can easily cause lens deformation and affect the processing accuracy. Utility Model Content

[0004] (a) Technical problems to be solved

[0023] The clamping mechanism 2 includes a clamping seat 21 fixedly connected to the upper part of the two connecting seats 35 facing each other. The two clamping seats 21 have a first arc-shaped groove 22, a second arc-shaped groove 23, and a third arc-shaped groove 24 equally spaced from top to bottom at their facing ends. The widths of the first arc-shaped groove 22, the second arc-shaped groove 23, and the third arc-shaped groove 24 decrease progressively. Anti-slip rubber strips 25 are fixedly connected to the inner walls of the arc-shaped grooves 22, 23, and 24. A through groove 2 is formed in the bottom wall of the third arc-shaped groove 24. 6.

At the same time, the inner wall of the arc-shaped groove is fixedly connected with anti-slip rubber strips 25. By adopting a distributed clamping method, that is, the arc-shaped inner wall of the arc-shaped groove and the anti-slip rubber strips 25 thereon form a whole-surface elastic clamping structure. When clamping and fixing the concave and convex lenses to be processed, the clamping force is evenly distributed on the lens surface, reducing deformation.

[0024] A mounting hole 12 is provided between the upper and lower side walls at both ends of the base 11. The clamping fixture for processing the overall concave and convex lens can be fixedly installed by using the mounting hole 12 on the base 11 in conjunction with the mounting components.

The front ends of the two connecting rods 36 are respectively fixedly connected to the connecting seats 35 on their corresponding sides.

[0026] The working principle of this utility model is as follows: It adopts an automated clamping structure design. It is equipped with a drive mechanism 3 in conjunction with the clamping mechanism 2. The power source is a drive motor 31. The drive end is equipped with a gear 32 and rack 33 transmission mechanism, which can drive the two clamping seats 21 of the clamping mechanism 2 to move. The drive motor 31 can be connected to the control terminal of the concave and convex lens processing equipment. Through the control program of the control terminal, the clamping mechanism 2 can realize the rapid positioning and clamping of the concave and convex lens to be processed, which improves the clamping efficiency. Since the two clamping seats 21 are symmetrically arranged and each has multiple arc-shaped grooves of different sizes from top to bottom, it can adapt to various sizes of concave and convex lenses to be processed and perform adaptive positioning and clamping. At the same time, the inner wall of the arc-shaped groove is fixedly connected with an anti-slip rubber strip 25. By adopting a distributed clamping method, that is, the arc-shaped inner wall of the arc-shaped groove and the anti-slip rubber strip 25 thereon form a whole-surface elastic clamping structure. When clamping and fixing the concave and convex lens to be processed, the clamping force is evenly distributed on the lens surface, reducing deformation.
