Description

Technical Field

[0001] This utility model relates to the field of lens hardening technology, specifically to a lens hardening fixture. Background Technology

[0002] In the process of hardening eyeglass lenses, fixtures are the core equipment to ensure the uniformity of lens hardening and improve the product qualification rate. Their structural rationality directly affects the forming quality of the hardened layer.

[0003] In practical applications, most traditional lens hardening fixtures lack precise synchronous positioning mechanisms. This can lead to asynchronous movement of the lenses during descent, preventing them from entering the hardening liquid pool simultaneously and evenly. Consequently, some areas may not have sufficient contact with the hardening liquid, resulting in inconsistent hardened layer thickness and significant differences in abrasion resistance. Furthermore, the fixtures are prone to shaking during immersion and transfer processes, causing localized accumulation and positional shifts in the lenses. This disrupts the flow stability of the hardening liquid, leading to scratches, bubbles, or incomplete hardening on the lens surface. This significantly increases the defect rate and severely impacts production efficiency and product quality.

[0004] Therefore, a lens hardening fixture is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a lens hardening fixture that can solve the problems of asynchronous movement of the lens during descent, shaking during soaking and transfer, local accumulation and displacement of the lens, and disruption of the flow stability of the hardening fluid.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A frame is included, with two hooks fixedly connected to the inner surface of the frame. Each hook has a crossbeam, and each crossbeam has a fixed rod fixedly connected to its side surface. Each fixed rod has a positioning block, and each positioning block has a fixed bracket at both ends. Each fixed bracket has two positioning blocks at both ends. Each of the six positioning blocks has multiple positioning holes, and each of the four fixed brackets has three fixed plates. Each of the twelve fixed plates has insertion holes, and each of the twelve insertion holes has a positioning rod on its inner surface. Each positioning rod has multiple hooks, and the other end of each hook has a clamping assembly. Each of the six positioning blocks has twelve sliding grooves fixedly connected to its lower surface, and each of the twelve sliding grooves has a clamping plate slidably connected to its inner surface. Each of the twelve sliding grooves has a bidirectional lead screw rotatably connected to its inner surface, and the bidirectional lead screw is threadedly connected to the clamping plate.

[0007] Preferably, each of the twelve fixing plates and the four fixing brackets is provided with a threaded hole, and a nut is threaded onto the inner surface of the threaded hole.

[0008] Preferably, the other end of the second hook is located on the inner surface of the positioning hole, which is located above the clamp assembly.

[0009] Preferably, the twelve clamping plates are designed symmetrically in pairs, and one end of the bidirectional lead screw extends through to the outer surface of the slide groove.

[0010] Preferably, a knob is fixedly connected to one end of the bidirectional lead screw, and the bidirectional lead screw is driven by the knob.

[0011] Preferably, all six positioning blocks are located below the positioning rod, and the fixing bracket is fixedly connected to the positioning blocks.

[0012] Preferably, each of the plurality of clamping assemblies is provided with a grid frame, and the clamping assemblies are located below the positioning block.

[0013] Preferably, all of the two hooks are located above the positioning holes, and the two hooks are slidably connected to the outer surface of the positioning rod.

[0014] Compared with the prior art, this utility model provides a lens hardening clamping fixture, which has the following beneficial effects: 1. By fixing the position of hook two with the positioning rod, the clamp assembly can make the grid frame descend simultaneously, so that the grid frame can enter the hardening liquid pool evenly and the eyeglass lens can be in uniform contact with the hardening liquid.

[0015] 2. By using a knob to drive a two-way lead screw to control the connection between the clamping plate and the hook two and the clamping assembly, the stability of the hook two is further enhanced, preventing the hook two from shaking during operation and causing local accumulation of the lens, resulting in poor hardening quality and an increase in defective products.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 - Figure 3 The spectacle lens hardening fixture in this embodiment includes: Figure 1 As shown, the system includes a frame 1. Two hooks 19 are fixedly connected to the inner surface of the frame 1. Each hook 19 has a crossbeam 18. Each crossbeam 18 has a fixing rod 2 fixedly connected to its side surface. Each fixing rod 2 has a positioning block 13. Each positioning block 13 has a fixing bracket 3 at both ends. Each fixing bracket 3 has two positioning blocks 13 at both ends. Each of the six positioning blocks 13 has multiple positioning holes 12. Each of the four fixing brackets 3 has three fixing plates 16. Each of the twelve fixing plates 16 has insertion holes 5. The inner surface of each of the twelve insertion holes 5 has a positioning rod 6. Each positioning rod 6 has multiple hooks 11. The additional hooks 11... One end is equipped with a clamp assembly 10. The lower surfaces of the six positioning blocks 13 are all fixedly connected with twelve sliding grooves 7. The inner surfaces of the twelve sliding grooves 7 are all slidably connected with clamping plates 15. The inner surfaces of the twelve sliding grooves 7 are all rotatably connected with bidirectional lead screws 8. The bidirectional lead screws 8 and clamping plates 15 are threaded together. The frame 1 is installed on the workbench so that hook 19 can be firmly fixed above the workbench. The operator turns the knob 14, and the knob 14 drives the bidirectional lead screw 8 to control the clamping plates 15 to clamp and fix hook 2 11. This can prevent hook 2 11 from shaking when the clamp assembly 10 moves, so that the lens can be evenly contacted with the hardening liquid and prevent local accumulation of the lens, which would lead to poor hardening quality.

[0021] Please see Figure 2 - Figure 3Each of the twelve fixed plates 16 and the four fixed brackets 3 is provided with a threaded hole 17. The inner surface of the threaded hole 17 is threaded with a nut 4. The twelve clamping plates 15 are designed symmetrically in pairs. One end of the bidirectional lead screw 8 passes through the outer surface of the slide groove 7. One end of the bidirectional lead screw 8 is fixedly connected to a knob 14. The bidirectional lead screw 8 is driven by the knob 14. The second hook 11 is slidably connected to the outer surface of the positioning rod 6. The operator places the crossbeam 18 on the first hook 19, and then turns the nut 4 to fix the fixed bracket 3, the fixed rod 2, the fixed plate 16 and the positioning block 13. Then the positioning rod 6 is placed on the inner surface of the insertion hole 5. Then the second hook 11 is passed through the positioning hole 12 on the positioning block 13. The operator places the eyeglass lens in the grid frame 9 on the clamping assembly 10 (one eyeglass lens corresponds to one grid frame 9). Then the clamping assembly 10 is installed on the other end of the second hook 11.

[0022] Please see Figure 5 The other end of hook 11 is located on the inner surface of positioning hole 12. Positioning hole 12 is located above clamp assembly 10. Six positioning blocks 13 are all located below positioning rod 6. Fixed bracket 3 is fixedly connected to positioning block 13. Multiple clamp assemblies 10 are provided with grid frame 9. Clamp assembly 10 is located below positioning block 13. Multiple hooks 11 are all located above positioning hole 12. The position of hook 11 is fixed by positioning rod 6 so that clamp assembly 10 can make grid frame 9 descend at the same time so that grid frame 9 can enter hardening liquid pool evenly so that the lens can be in uniform contact with hardening liquid.

[0023] The working principle of the above embodiment is as follows: The operator places the crossbeam 18 on the hook 19, then tightens the nut 4 to fix the fixed bracket 3, fixed rod 2, fixed plate 16 and positioning block 13. Then, the positioning rod 6 is placed on the inner surface of the insertion hole 5. Then, the hook 2 11 is passed through the positioning hole 12 on the positioning block 13. The operator places the lens in the grid frame 9 on the clamp assembly 10 (one lens corresponds to one grid frame 9). Then, the clamp assembly 10 is installed on the other end of the hook 2 11. Finally, the operator turns the knob 14. The knob 14 drives the bidirectional screw 8 to control the clamp plate 15 to clamp and fix the hook 2 11. This can prevent the hook 2 11 from shaking when the clamp assembly 10 moves, so that the lens can be evenly contacted with the hardening liquid and prevent local accumulation of the lens, which would lead to poor hardening quality.

[0024] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
