[0002] Optical glass is a glass material specially designed for optical applications. It has a series of special physical and chemical properties that enable it to perform well in optical systems and equipment. Optical glass plays an important role in modern optical technology. Its special properties make it an ideal choice for manufacturing various optical components and systems. Optical glass needs to be positioned and clamped during processing.

[0003] For example, a Chinese patent discloses: a positioning fixture for optical glass processing, patent number: CN219542886U.

[0026] The embodiment of the present application provides a positioning fixture for optical glass processing, which effectively solves the problem that the device needs to manually rotate the two optical axes for clamping during clamping, and the clamping device lacks the effect of automatic centering. In order to ensure the accurate positioning position, it is necessary to perform centering before clamping each time, and then rotate the optical axis for clamping, which increases the complexity and time cost of operation. The optical glass to be clamped and positioned is placed on the optical platform, and the cylinder is started. The cylinder drives the connecting block to slide through the sliding block. During the sliding process of the connecting block, the rectangular block is pushed to rotate by the first connecting rod. The rotation of the rectangular block drives the connecting block at the other end to slide toward the center. During the sliding process of the connecting block, the positioning rod is driven to rotate by the second connecting rod and the third connecting rod. The rotation of the positioning rod drives the clamping rod to rotate through the rotating plate to clamp the optical glass. The cylinder drives the four clamping rods to rotate toward the center at the same time to firmly clamp the optical glass. No manual operation is required, which reduces the work intensity. When the four clamping rods rotate and clamp, they drive the optical glass to slide and automatically center it, ensuring that the clamped position of the workpiece is stable each time, facilitating processing operations and improving processing accuracy.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application effectively solves the problem that the device needs to manually rotate the two optical axes for clamping during clamping, and the clamping device lacks the effect of automatic centering. In order to ensure the accurate positioning position, it is necessary to perform centering positioning before clamping each time, and then rotate the optical axis for clamping, which increases the complexity of operation and the time cost. The overall idea is as follows: it includes a workbench 11, the upper end of the workbench 11 is fixedly connected to an optical platform 12, a rectangular block 13 is rotatably connected inside the workbench 11, a first connecting rod 14 is sleeved on the outer surface of the rectangular block 13, and a connecting block 15 is sleeved on the end of the first connecting rod 14 away from the rectangular block 13. The optical glass that needs to be clamped and positioned is placed on the optical platform 12, and the cylinder 16 is started. The cylinder 16 drives the connecting block 15 to slide through the sliding block 17. During the sliding process of the connecting block 15, the first connecting rod 14 pushes the rectangular block 13 to rotate, and the rotation of the rectangular block 13 drives the connecting block 15 at the other end to slide toward the center.

[0029] The lower end of the workbench 11 is fixedly connected to a cylinder 16, and one end of the cylinder 16 close to the optical platform 12 is fixedly connected to a clamping mechanism, and the clamping mechanism includes a sliding block 17, and the sliding block 17 is fixedly connected to one end of the cylinder 16 close to the optical platform 12, and the sliding block 17 is fixedly connected to the lower end of the connecting block 15, and the connecting block 15 is slidably connected to the inside of the workbench 11, and the second connecting rod 18 is rotatably connected inside the connecting block 15, and the third connecting rod 19 is rotatably connected inside the second connecting rod 18, and the lower end of the workbench 11 is fixedly connected to a positioning rod 21, and the third connecting rod 19 is rotatably connected to the outer surface of the positioning rod 21, and the outer surface of the positioning rod 21 is sleeved with a rotating plate 22, and the rotating plate 22 is located above the third connecting rod 19, and the rotating plate 22 is sleeved with a clamping rod 23, and the outer surface of the clamping rod 23 is sleeved with a rubber jacket 24, and the workbench 11 and the optical platform A slide groove 25 is provided inside the table 12, and the clamping rod 23 is rotatably connected inside the slide groove 25. During the sliding process of the connecting block 15, the positioning rod 21 is driven to rotate through the second connecting rod 18 and the third connecting rod 19. The rotation of the positioning rod 21 drives the clamping rod 23 to rotate through the rotating plate 22 to clamp the optical glass. During the clamping process, the rubber jacket 24 connected to the outer surface of the clamping rod 23 is used to prevent scratches on the surface of the optical glass. The four clamping rods 23 are driven by the cylinder 16 to rotate toward the center at the same time to firmly clamp the optical glass. No manual operation is required, which reduces the work intensity. When the four clamping rods 23 rotate and clamp, they drive the optical glass to slide and automatically center it, ensuring that the clamped position of the workpiece is stable each time, facilitating processing operations and improving processing accuracy. The clamping position can be adjusted by adjusting the stroke distance of the cylinder 16 to adapt to optical glasses of different sizes.

[0030] A spring 26 is fixedly connected inside the workbench 11, and an extrusion block 27 is sleeved inside the spring 26. The extrusion block 27 is slidably connected inside the workbench 11. A lifting block 28 is slidably connected inside the optical platform 12. The lifting block 28 and the extrusion block 27 are on the same horizontal line. After the clamping process is completed, the extrusion block 27 is pushed inward, and the extrusion block 27 slides upward to push the lifting block 28 to slide, and the processed glass is pushed upward, which is convenient for the staff to take it, avoids scratches caused by the smooth surface of the glass when taking it, and improves the convenience of the taking operation. After taking it, the extrusion block 27 is driven by the spring 26 to slide and reset.

[0031] In view of the problems existing in the prior art, the utility model provides a positioning fixture for optical glass processing. The optical glass to be clamped and positioned is placed on an optical platform 12, and the cylinder 16 is started. The cylinder 16 drives the connecting block 15 to slide through the sliding block 17. During the sliding process of the connecting block 15, the rectangular block 13 is pushed to rotate by the first connecting rod 14. The rotation of the rectangular block 13 drives the connecting block 15 at the other end to slide toward the center. During the sliding process of the connecting block 15, the positioning rod 21 is driven to rotate by the second connecting rod 18 and the third connecting rod 19. The rotation of the positioning rod 21 drives the clamping rod 23 to rotate through the rotating plate 22 to clamp the optical glass. The cylinder 16 drives four clamping rods 23 to rotate toward the center at the same time to firmly clamp the optical glass. No manual operation is required, which reduces the work intensity. When the four clamping rods 23 rotate and clamp, they drive the optical glass to slide and automatically center it, ensuring that the clamped position of the workpiece is stable each time, facilitating the processing operation and improving the processing accuracy.

[0032] Working principle:

[0033] In the first step, the optical glass to be clamped and positioned is placed on the optical platform 12, and the cylinder 16 is started. The cylinder 16 drives the connecting block 15 to slide through the sliding block 17. During the sliding process of the connecting block 15, the rectangular block 13 is pushed to rotate by the first connecting rod 14. The rotation of the rectangular block 13 drives the connecting block 15 at the other end to slide toward the center. During the sliding process of the connecting block 15, the positioning rod 21 is driven to rotate by the second connecting rod 18 and the third connecting rod 19. The rotation of the positioning rod 21 drives the clamping rod 23 to rotate through the rotating plate 22 to clamp the optical glass. During the clamping process, the rubber jacket 24 connected to the outer surface of the clamping rod 23 is used to prevent scratches on the surface of the optical glass. The cylinder 16 drives the four clamping rods 23 to rotate toward the center at the same time to firmly clamp the optical glass. No manual operation is required, which reduces the work intensity. When the four clamping rods 23 rotate and clamp, they drive the optical glass to slide and automatically center it, ensuring that the clamped position of the workpiece is stable each time, facilitating the processing operation and improving the processing accuracy. The clamping position can be adjusted by adjusting the stroke distance of the cylinder 16 to adapt to optical glasses of different sizes.

[0034] In the second step, after the clamping process is completed, the extrusion block 27 is pushed inward, and the extrusion block 27 slides upward to squeeze and push the lifting block 28 to slide, so as to push the processed glass upward, which is convenient for the staff to take it and avoids scratches caused by the smooth surface of the glass when taking it, thereby improving the convenience of the taking operation. After taking it, the spring 26 drives the extrusion block 27 to slide and reset.
