DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] Reference Figure 1-Figure 3A thickness detection device for an optical lens comprises a fixed base plate 1, a connecting bracket 2 is fixedly connected to the top of the fixed base plate 1, a fixed outer frame 6 is arranged on the inner side wall of the connecting bracket 2, the bottom end of the fixed outer frame 6 is fixedly connected to the top of the fixed base plate 1, a plurality of threaded rods 3 corresponding to the fixed outer frame 6 are threadedly connected to the upper end surface of the connecting bracket 2, a fixing rod 4 is arranged at the bottom end of each threaded rod 3, an upper pressing block 5 is fixedly connected to the bottom end of each fixing rod 4, a fixing bracket 9 is rotatably sleeved on each fixing rod 4, and each fixing bracket 9 is threadedly sleeved on each fixing rod 4, and each fixing bracket 9 is threadedly sleeved on each fixing rod 4. The mounting bracket is fixedly connected to the fixed base plate 1, and each fixed bracket 9 is provided with an amplifying structure. The top of the fixed base plate 1 is fixedly connected with a fixed plate 13, and the side wall of the fixed plate 13 is slidably connected with a detection block 16. The lens is set in the fixed outer frame 6, and the threaded rod 3 is rotated. Under the action of the thread, the threaded rod 3 moves downward, and the fixed rod 4 and the upper pressing block 5 move accordingly, so that the upper pressing block 5 is pressed on the lens. Under the action of the amplifying structure, the detection block 16 moves upward, and the thickness of the lens can be obtained by the distance the detection block 16 moves.
[0019] The amplification structure includes a fixed rack 10 fixedly connected to the end of the fixed bracket 9, and a fixed gear 11 meshing with the fixed bracket 9 is arranged on one side of each fixed bracket 9. The fixed gear 11 is fixedly connected to a fixed shaft 12 at one end close to the fixed plate 13, and each fixed shaft 12 is rotatably connected to the corresponding fixed plate 13 at one end away from the fixed gear 11. A connecting gear 14 is rotatably sleeved on each fixed shaft 12, and the diameter of the connecting gear 14 is larger than the fixed gear 11. A connecting rack 17 corresponding to it is arranged at one end of each connecting gear 14, and the connecting rack 17 is connected to the corresponding fixed plate 13. The corresponding connecting gear 14 is meshed, and a connecting block 15 is fixedly connected to the side wall of each connecting rack 17, and each connecting block 15 is fixedly connected to the bottom end of the corresponding detection block 16. During the movement of the fixed rod 4, the fixed bracket 9 and the fixed rack 10 move accordingly. When the fixed rack 10 moves, the fixed gear 11 meshed with it rotates, driving the fixed shaft 12 and the connecting gear 14 to rotate. The rotation of the connecting gear 14 causes the connecting rack 17 meshed with it to move. When the connecting rack 17 moves, it drives the connecting block 15 to move, thereby causing the detection block 16 to move together.
[0020] A moving groove is formed at the bottom end of each threaded rod 3, and each fixed rod 4 is slidably connected to the inner wall of the moving groove. A buffer spring is fixedly connected to the top end of each fixed rod 4, and one end of each buffer spring away from the fixed rod 4 is fixedly connected to the inner wall of the corresponding moving groove. The buffer spring can play a buffering role to prevent the fixed rod 4 and the upper pressing block 5 from crushing the lens when the threaded rod 3 moves downward;
[0021] An elastic expansion plate 7 is fixedly connected to the front and rear inner walls of each fixed outer frame 6, and a fixed clamping block 8 is fixedly connected to the end of each elastic expansion plate 7, and the lens is set to the inner side of the fixed outer frame 6 and fixedly clamped by the fixed clamping block 8; the top of each threaded rod 3 is fixedly connected to a rotating block, and the threaded rod 3 is rotated by rotating the rotating block; a scale is provided on the side wall of each fixed plate 13 close to the detection block 16, and the thickness of the lens can be easily observed through the scale. The top of the scale is the zero point, and the scale below is the thickness of the lens.
[0022] When the lens is in use, the lens is set to the inner side of the fixed outer frame 6, and the lens is fixedly clamped by the fixed clamping block 8. Then, the rotating block is rotated to rotate the threaded rod 3. Under the action of the thread, the threaded rod 3 moves downward, and the fixed rod 4 and the upper pressing block 5 move accordingly, so that the upper pressing block 5 is pressed on the lens. The buffer spring can play a buffering effect to prevent the fixed rod 4 and the upper pressing block 5 from crushing the lens when the threaded rod 3 moves downward. During the movement of the fixed rod 4, the fixed bracket 9 and the fixed rack 10 move accordingly. When the fixed rack 10 moves, the fixed gear 11 meshed with it rotates, driving the fixed shaft 12 and the connecting gear 14 to rotate. The rotation of the connecting gear 14 causes the connecting rack 17 meshed with it to move. When the connecting rack 17 moves, it drives the connecting block 15 to move, so that the detection block 16 moves together, and the thickness of the lens can be conveniently observed through the scale and the detection block 16.
