Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing, in particular to a polishing device for processing optical glass lenses. Background Art

[0002] Optical glass lenses are lenses used in optical instruments such as glasses, telescopes, and microscopes. They are high-precision optical components. During the production process, in order to ensure the roundness and smoothness of the surface of the optical glass lenses, the optical glass lenses need to be ground and polished.

[0003] Before polishing an optical glass lens, it needs to be clamped and positioned to prevent the lens from shifting during the polishing process and affecting the processing quality. However, the existing clamping structure is too cumbersome and cannot quickly remove the polished lens. In addition, when polishing the glass lens, polishing rollers of various mesh sizes are required to process the glass lens. After polishing, the glass lens needs to be moved under another polishing roller with a lower mesh size, and this reciprocating process results in low processing efficiency. Utility Model Content

In addition, the glass lens needs to be moved under another polishing roller with a lower mesh number after polishing, resulting in low processing efficiency. A polishing device for processing optical glass lenses is proposed.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1

[0025] like Figures 1-6As shown, the utility model provides a technical solution: a polishing device for processing optical glass lenses, including a base 1 and a stage 2, the stage 2 is fixedly installed on the top of the base 1, the top of the base 1 is fixedly connected to a frame 11 and a positioning rod 12, the top of the frame 11 is fixedly installed with a first motor 3 and a second motor 4, the output end of the first motor 3 is fixedly connected to a connecting shaft 31, the bottom of the connecting shaft 31 is fixedly connected to a mounting seat 5, the interior of the mounting seat 5 is provided with four through holes 501, the output end of the second motor 4 is fixedly connected to a lead screw 41, the surface of the lead screw 41 is threadedly connected to a movable plate 42, the top of the movable plate 42 is fixedly installed A third motor 6 is installed, and sliding blocks 7 are provided inside the four through holes 501. A storage groove 201 is provided on the top of the worktable 2, and a threaded rotating rod 21 is provided at the top of the outer wall of the worktable 2. The surface of the threaded rotating rod 21 is threadedly connected to the inner wall of the worktable 2, and a clamping block 22 is fixedly connected to one side of the threaded rotating rod 21. A cavity 202 is provided inside the worktable 2, and a movable seat 23 is movably installed inside the cavity 202. A push rod 24 is movably installed at the bottom end of the outer wall of the worktable 2, and a fixed rod 25 is fixedly connected to the top of the inner wall of the cavity 202. A spring 26 is movably sleeved on the surface of the fixed rod 25, and one end of the movable seat 23 is slidably installed on the surface of the fixed rod 25.

[0026] In this embodiment, the lens to be ground and polished is placed on the top of the storage groove 201, and then the threaded rods 21 at both ends are rotated to move it into the storage groove 201. The clamping block 22 at one end of the threaded rod 21 approaches the lens and clamps it. At the same time, the storage groove 201 can limit the lens to prevent it from slipping during the polishing process, thereby improving its stability during the polishing process. Conversely, the threaded rod 21 is rotated in the opposite direction to make them move away from each other to release the fixation of the lens, and then the push rod 24 is pressed to move it into the cavity 202. The push rod 24 gradually squeezes the bottom of the movable seat 23 to move it upward, and the movable seat 23 slides on the surface of the fixed rod 25 to squeeze the spring 26. The movable seat 23 rises and pushes the lens upward, thereby facilitating the removal of the lens from the storage groove 201.

[0027] Example 2

[0028] like Figures 1-6 As shown, the movable plate 42 is slidably installed on the surface of the positioning rod 12, the output end of the third motor 6 is fixedly connected to the transmission rod 61, and a slot 701 is provided on the top of the sliding block 7.

The inside of the through hole 501 is fixedly installed with a fixed rod 2 51, and the surface of the fixed rod 2 51 is movably sleeved with a spring 2 52. A ring 71 is movably installed on the side of the sliding block 7, and a polishing cloth 72 is fixedly connected to the bottom of the sliding block 7. The ring 71 is slidably installed on the surface of the fixed rod 2 51.

[0029] In this embodiment, after the lens is clamped and fixed, the second motor 4 is started to drive the lead screw 41 to rotate, the movable plate 42 is downward on its surface, and the third motor 6 and the transmission rod 61 are lowered together. The transmission rod 61 moves downward to be embedded in the card slot 701 and squeezes the sliding block 7. At this time, the ring 71 slides on the surface of the second fixed rod 51 to squeeze the second spring 52, and the sliding block 7 slides out from the through hole 501. The polishing cloth 72 at the bottom of the sliding block 7 contacts the lens, and the third motor 6 is started to drive the transmission rod 61 and the sliding block 7 to rotate. The ring 71 is internally provided with a ball bearing to reduce the wear between the ring 71 and the sliding block 7. After the first polishing of the lens is completed, the second motor 4 is controlled to drive the lead screw 41 to reverse, so that the third motor 6 and the transmission rod 61 move back and rise, and the sliding block 7 moves back and resets through the rebound of the spring 2 52. The first motor 3 is started to rotate the mounting base 5, and the polishing cloth with a smaller number is rotated to the top of the lens. The first polishing operation is repeated to complete the multi-mesh polishing of the lens. The lens can be polished with a lower mesh number without transferring it, thereby improving the processing efficiency.

[0030] The working principle of this embodiment is as follows: the lens is placed on the top of the storage slot 201, and then the threaded rotating rods 21 at both ends are rotated, the clamping block 22 approaches the lens and clamps it, and then the second motor 4 is started to drive the lead screw 41 to rotate, so that the third motor 6 and the transmission rod 61 are lowered together, and the transmission rod 61 moves downward to be embedded in the card slot 701 and squeezes the sliding block 7. The sliding block moves down and the polishing cloth 72 at the bottom contacts the lens. The third motor 6 is started to drive the transmission rod 61 and the sliding block 7 to rotate, and the lens is polished for the first time. The second motor 4 is controlled to drive the lead screw 41 to reverse, so that the third motor 6 and the transmission rod 61 move back and rise, and the first motor 3 is started to rotate the mounting seat 5, and a smaller number of polishing cloths are rotated to the top of the lens. The first polishing operation is repeated to complete the polishing of multiple lenses. Then, the threaded rotating rod 21 is rotated in the opposite direction, and the push rod 24 is pressed to squeeze the bottom of the movable seat 23. The movable seat 23 rises and lifts the lens upward, thereby facilitating the removal of the lens from the storage slot 201.
