Description

Technical Field

[0001] This utility model relates to the field of optical lens clamping technology, specifically a clamping structure for optical lens processing. Background Technology

[0002] The clamping structure for optical lens processing is a device specifically designed for optical lens manufacturing, aiming to ensure the stability and precision of lenses during processing. Clamping structures are required to hold optical lenses in place during both production and inspection. The cage-type mounting base has three clamping rods rotatably connected in the center. Through a lever, internal gears, and torsion springs, the three clamping rods can be engaged simultaneously, placing the lens between them. Releasing the lever and allowing the torsion springs to return to their original position tightens the three clamping rods. This structure makes the cage-type mounting base suitable for lenses of different sizes.

[0003] When clamping a lens, one hand moves a lever while the other holds the lens and places it between three clamping rods. However, the three clamping rods are open from front to back, causing the lens to sometimes extend too far into the rods and slip out of the clamping position, resulting in slow clamping speed. Therefore, a clamping structure for optical lens processing is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a clamping structure for optical lens processing, thereby solving the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution:

[0005] This utility model relates to a clamping structure for optical lens processing, comprising:

[0006] A cage-type mounting base includes a support plate, a shaped connecting block, a clamping rod, and a lever. There are two support plates with a hole in the middle. The shaped connecting block is fixed to the outer ring of the support plate. The clamping rod is rotatably connected between the two support plates. The lever is movably connected to the outer ring of the middle of the two support plates.

[0007] The first limiting component includes a rotating shaft, a limiting plate, a fixing plate, and a spring. One end of the rotating shaft is fixed to one side of one of the clamping rods. One end of the limiting plate is rotatably connected to the rotating shaft. The fixing plate is fixed to the other end of the rotating shaft. The spring is sleeved on the rotating shaft and one end is fixed to the fixing plate.

[0008] Furthermore, the first limiting component also includes a through hole and a connecting ring. The through hole is formed on the limiting plate and sleeved on the rotating shaft, and the connecting ring is sleeved on the rotating shaft and fixed to the other end of the spring.

[0009] Furthermore, the first limiting component also includes a rubber pad, which is fixed to the end of the limiting plate away from the rotating shaft.

[0010] Furthermore, one side of the limiting plate is movably connected to the side of the clamping rod, and the other side is movably connected to the side of the connecting ring.

[0011] Furthermore, the cage-type mounting base also includes a support column, which is screwed to the lower end of the irregular connecting block.

[0012] Furthermore, it also includes a second limiting component, which includes an L-shaped support plate, a threaded hole, an adjusting rod, and an inclined block. The L-shaped support plate is fixed to the side of the irregular connecting block, the threaded hole is opened in the middle of the side of the L-shaped support plate, the adjusting rod is screwed into the threaded hole, and the inclined block is rotatably connected to one end of the adjusting rod.

[0013] Furthermore, the second limiting component also includes a limiting hole and a limiting rod. The limiting hole is opened on the side of the L-shaped support plate and is located above the threaded hole. One end of the limiting rod is fixed to the side of the inclined block, and the other end is inserted into the limiting hole.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a first limiting component. By moving a lever, the three clamping rods are opened, and the limiting plate is positioned behind the clamping rods. Holding the lens, the user places it inside the three clamping rods until their fingers are close to the rubber pad on the limiting plate. Releasing the lever allows the three clamping rods to clamp the lens. Rotating the lever pulls the limiting plate from behind the clamping rods, causing the connecting ring to move along the pivot axis, compressing the spring. Rotating the limiting plate upwards, it moves away from the lens. Releasing the limiting plate releases the spring on the fixing plate, causing the limiting plate on the side of the connecting ring to press against the clamping rods. This design allows for quick placement of the lens between the clamping rods, increasing clamping speed. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-3 As shown, this utility model is a clamping structure for optical lens processing, comprising:

[0026] The cage-type mounting base includes a support plate 11, a special-shaped connecting block 12, a clamping rod 13, and a lever 14. There are two support plates 11 with a hole in the middle. The special-shaped connecting block 12 is fixed to the outer ring of the support plate 11. The clamping rod 13 is rotatably connected between the two support plates 11. The lever 14 is movably connected to the outer ring of the middle of the two support plates 11.

[0027] The cage-type mounting base also includes a support column 10, which is screwed to the lower end of the irregular connecting block 12;

[0028] The support column 10 and support plate 11 provide support. The irregular connecting block 12 is used to connect the two support plates 11 and also to connect the support column 10. The clamping rod 13 is used to clamp the lens. The toggle block 14 is used to drive the clamping rod 13 to open.

[0029] The first limiting component includes a rotating shaft 20, a limiting plate 21, a fixing plate 24, and a spring 25. One end of the rotating shaft 20 is fixed to one side of one of the clamping rods 13. One end of the limiting plate 21 is rotatably connected to the rotating shaft 20. The fixing plate 24 is fixed to the other end of the rotating shaft 20. The spring 25 is sleeved on the rotating shaft 20 and one end is fixed to the fixing plate 24.

[0030] The first limiting component also includes a through hole 22 and a connecting ring 26. The through hole 22 is opened on the limiting plate 21 and sleeved on the rotating shaft 20. The connecting ring 26 is sleeved on the rotating shaft 20 and fixed to the other end of the spring 25.

[0031] The first limiting component also includes a rubber pad 23, which is fixed to the end of the limiting plate 21 away from the rotating shaft 20;

[0032] The limiting plate 21 is movably connected to the side of the clamping rod 13 on one side and movably connected to the side of the connecting ring 26 on the other side;

[0033] The rotating shaft 20 provides support and facilitates the rotation of the limiting plate 21. The limiting plate 21 provides a limiting function. The through hole 22 facilitates the connection of the limiting plate 21 to the rotating shaft 20. The rubber pad 23 prevents damage to the lens. The fixing plate 24 is used to fix the spring 25. The connecting ring 26 is used to connect the other end of the spring 25. The spring 25 has a telescopic function.

[0034] Working principle:

[0035] Move the lever 14 to open the three clamping rods 13. At this time, the limiting plate 21 is located behind the clamping rods 13. Hold the lens and place it inside the three clamping rods 13 until your fingers are close to the rubber pad 23 on the limiting plate 21. Release the lever 14, and the three clamping rods 13 clamp the lens. At this time, rotate the limiting plate 21 from the back of the clamping rods 13, which will drive the connecting ring 26 to move along the rotating shaft 20. The spring 25 will be compressed. Rotate the limiting plate 21 to make it rotate upward and away from the lens. Release the limiting plate 21, and the spring 25 on the fixing plate 24 will extend, causing the limiting plate 21 on the side of the connecting ring 26 to stick tightly to the clamping rods 13.

[0036] This step allows the lens to be quickly placed between the clamping rods 13, increasing the clamping speed.

[0037] Please see Figure 2 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The second limiting component includes an L-shaped support plate 30, a threaded hole 31, an adjusting rod 33, and an inclined block 35. The L-shaped support plate 30 is fixed to the side of the irregular connecting block 12. The threaded hole 31 is opened in the middle of the side of the L-shaped support plate 30. The adjusting rod 33 is screwed into the threaded hole 31. The inclined block 35 is rotatably connected to one end of the adjusting rod 33.

[0039] The second limiting component also includes a limiting hole 32 and a limiting rod 34. The limiting hole 32 is opened on the side of the L-shaped support plate 30 and is located above the threaded hole 31. One end of the limiting rod 34 is fixed to the side of the inclined block 35, and the other end is inserted into the limiting hole 32.

[0040] The L-shaped support plate 30 provides support, while the threaded hole 31 and adjusting rod 33 provide adjustment for moving and positioning the inclined block 35. The limiting hole 32 and limiting rod 34 provide limiting to prevent the inclined block 35 from shifting position when it moves. The inclined block 35 is used to position the lever 14.

[0041] Working principle:

[0042] After the clamping rod 13 clamps the lens, the adjusting rod 33 in the threaded hole 31 is rotated to move the inclined block 35. At the same time, the limiting rod 34 moves in the limiting hole 32. The inclined end of the inclined block 35 moves to the lower end of the lever 14 and abuts against the lever 14.

[0043] This step prevents the lever 13 from loosening due to external force causing the paddle 14 to shake when clamping the lens.
