AI Technical Summary
In lens cutting processing, it is difficult for the prior art to effectively complete the core retrieval of the lens because the two sides of the lens are uneven, resulting in difficulty in core retrieval.
A lens core retrieval tool is designed, using a low-speed rotation contact assembly and a high-speed rotation contact assembly. Through rotation in opposite directions and different rotation speeds, the concave and convex sides of the lens are respectively clamped to realize the core retrieval of the lens. The fixture includes a frame table, a low-speed rotation contact assembly and a high-speed rotation contact assembly, and uses a first rotating motor, a driving pinion, a reduction gear and a low-speed rotation resistance lever, and a second rotating motor, a driving gear, and a small-diameter gear shaft , driven gear pumping, pushing cylinder and high-speed rotation resistance lever to achieve core removal of different rotation contact speeds.
Through the synergy between the low-speed rotating contact assembly and the high-speed rotating contact assembly, the lens automatically completes the core retrieval during rotation, which improves the efficiency and difficulty of the lens core retrieval.

Abstract
Description
Technical Field
[0001] The utility model relates to a lens core removal jig. Background Art
[0002] In the field of lens cutting, before cutting the lens, it is necessary to complete the core extraction action on the lens, that is, to find the center of the circle. The general fixture is clamped on the two sides of the lens. Since the lens has two concave and convex sides, it is difficult to core. Therefore, it is necessary to design a lens core extraction fixture that can use one side of the lens to rotate at high speed and the other side to rotate at low speed to complete the core extraction action of the lens by using the rotation contact speed difference. Utility Model Content

[0004] The utility model includes a frame, a low-speed rotating contact component and a high-speed rotating contact component. The low-speed rotating contact component and the high-speed rotating contact component are adapted to be arranged on the frame, and the low-speed rotating contact component includes a first rotating motor, a driving pinion, a reduction gear and a low-speed rotating contact rod. The first rotating motor is adapted to be arranged on the frame, the driving pinion is adapted to be transmission-connected and arranged on the output end of the first rotating motor, the reduction gear is adapted to be movably mounted on the frame and transmission-engaged with the driving pinion, and the low-speed rotating contact rod is adapted to be horizontally fixedly connected to the reduction gear.
[0005] The high-speed rotating contact component includes a second rotating motor, a driving large gear, a small-diameter gear shaft, a driven gear pull, a pushing cylinder and a high-speed rotating contact rod. The second rotating motor is adapted to be arranged on the frame platform, the driving large gear is adapted to be transmission-connected to the output end of the second rotating motor, the small-diameter gear shaft and the driven gear pull are adapted to be movably mounted on the frame platform, the pushing cylinder is adapted to be mounted on the frame platform, the head end of the driven gear pull is adapted to be horizontally transmission-connected to the output end of the pushing cylinder, the small-diameter gear shaft is adapted to be transmission-engaged with the driving large gear, the driven gear pull is adapted to be movably transmission-engaged with the small-diameter gear shaft, the high-speed rotating contact rod is adapted to be horizontally fixedly arranged on the end of the driven gear pull and is adapted to be movably corresponding to the low-speed rotating contact rod.
[0006] The transmission rotation direction of the second rotating motor is opposite to that of the first rotating motor.
[0007] Beneficial effect: In the utility model, the low-speed rotating contact component and the high-speed rotating contact component rotate the concave and convex sides of the clamped lens respectively. By rotating the low-speed rotating contact component and the high-speed rotating contact component in opposite directions and at different speeds, the lens automatically completes the core-taking action during rotation. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] like Figure 1 As shown, the utility model includes a frame 1, a low-speed rotating contact component and a high-speed rotating contact component. The low-speed rotating contact component and the high-speed rotating contact component are adapted to be correspondingly arranged on the frame 1. The low-speed rotating contact component includes a first rotating motor 21, a driving pinion 22, a reduction gear 23 and a low-speed rotating contact rod 24. The first rotating motor 21 is adapted to be arranged on the frame 1, the driving pinion 22 is adapted to be transmission-connected to the output end of the first rotating motor 21, the reduction gear 23 is adapted to be movably mounted on the frame 1 and is transmission-engaged with the driving pinion 22, and the low-speed rotating contact rod 24 is adapted to be horizontally fixedly connected to the reduction gear 23.
[0010] The high-speed rotating contact component includes a second rotating motor 31, a driving large gear 32, a small-diameter gear shaft 33, a driven gear drawer 34, a pushing cylinder 35 and a high-speed rotating contact rod 36. The second rotating motor 31 is adapted to be set on the frame 1, and the driving large gear 32 is adapted to be transmission-connected to the output end of the second rotating motor 31. The small-diameter gear shaft 33 and the driven gear drawer 34 are adapted to be movably mounted on the frame 1. The pushing cylinder 35 is adapted to be mounted on the frame 1. The head end of the driven gear drawer 34 is adapted to be horizontally transmission-connected and set on the output end of the pushing cylinder 35. The small-diameter gear shaft 33 is adapted to be transmission-engaged with the driving large gear 32. The driven gear drawer 34 is adapted to be movably transmission-engaged with the small-diameter gear shaft 33. The high-speed rotating contact rod 36 is adapted to be horizontally fixedly set on the end of the driven gear drawer 34 and is adapted to be movably corresponding to the low-speed rotating contact rod 24.
[0011] The transmission rotation direction of the second rotating motor 31 is opposite to that of the first rotating motor 21 .
[0012] The rotation of the first rotating motor 21 drives the transmission of the small gear 22 and the large gear 23 to complete the speed reduction, thereby driving the low-speed rotating contact rod 24 to rotate at a low speed. The rotation of the second rotating motor 31 drives the transmission of the large gear 32 and the small-diameter gear shaft 33 to complete the speed increase, thereby driving the driven gear pump 34 to rotate at a high speed, and realizing the high-speed driving rotation of the high-speed rotating contact rod 36. During the rotation process, the push cylinder 35 pushes the driven gear pump 34 to make a linear motion on the small-diameter gear shaft 33, thereby driving the high-speed rotating contact rod 36 to move back and forth.
[0013] The low-speed rotating resistance rod 24 rotates and resists the convex surface of the lens, and the high-speed rotating resistance rod 36 rotates and resists the concave surface of the lens. The lens completes the core removal action in the rotating resistance of the two surfaces.
[0014] The utility model is suitable for the field of lens processing.
