Description

Technical Field

[0001] This utility model relates to the field of optical lens testing technology, and in particular to an auxiliary support for optical lens thickness testing. Background Technology

[0002] In the field of optics, the thickness measurement of optical lenses is a crucial task, as its accuracy directly affects the imaging quality and performance of optical systems. Optical lenses are widely used in various precision optical instruments, such as camera lenses, microscope objectives, and telescope eyepieces. Different types and applications of optical lenses have significant differences in specifications, including lens diameter, radius of curvature, and thickness range.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Many traditional optical lens thickness detection auxiliary supports use a fixed clamping structure. This structure is usually optimized for a specific specification or a few similar specifications of optical lenses. For example, the clamping claw spacing, shape and size of some supports are customized according to the standard diameter of circular lenses. When facing lenses with a diameter that is significantly smaller or larger than the standard size, there will be a situation where they cannot be effectively clamped. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing optical lens thickness detection auxiliary bracket adopts a fixed clamping structure, which has the disadvantage of not being able to effectively clamp lenses with diameters that are significantly smaller or larger than the standard size. Therefore, we propose an optical lens thickness detection auxiliary bracket.

[0005] To achieve the above objectives, this application adopts the following technical solution: an auxiliary support for optical lens thickness detection, comprising a base, an auxiliary support body fixedly connected to the top of the base, an adjusting block slidably connected to the surface of the auxiliary support body, an adjusting mechanism installed inside the adjusting block, an adjusting column fixedly connected to the front end of the adjusting block, a rotating column rotatably connected inside the adjusting column, a clamping rod slidably connected inside the rotating column, several limiting holes being provided at both ends of the clamping rod, arc blocks being fixedly connected to both ends of the adjusting column, adjusting grooves being provided at both ends of the rotating column, a circular block slidably connected inside the adjusting groove, and a limiting rod being fixedly connected to the side of the circular block near the inside of the adjusting groove.

[0006] Preferably, guide grooves are provided on both sides of the adjustment groove, and guide blocks are fixedly connected to both sides of the circular block, with the surface of the guide block slidingly connected to the inside of the guide groove.

[0007] Preferably, a storage spring is fixedly connected to the side of the circular block near the adjustment groove, and the side of the storage spring away from the circular block is fixedly connected to the interior of the adjustment groove.

[0008] Preferably, the inner wall of the adjusting column is provided with an annular groove, and an annular block is fixedly connected to the outer diameter surface of the rotating column, with the surface of the annular block being slidably connected to the interior of the annular groove.

[0009] Preferably, the size of the limiting rod is adapted to the size of the limiting hole, and the surface of the limiting rod is inserted into the interior of the limiting hole.

[0010] Preferably, a return spring is fixedly connected to the side of the adjusting column away from the ring block, and the side of the return spring away from the adjusting column is fixedly connected to the ring block.

[0011] The technical effects and advantages of this utility model are as follows: In this invention, the operator moves the clamping rod to fit the optical lens. After adjusting it to the appropriate position, the operator rotates the rotating column. As the rotating column rotates, it causes the round block to contact the thicker end of the arc block, which in turn pushes the round block to insert the limiting rod into the limiting hole. This allows the operator to secure the optical lens and also makes it convenient to replace the clamping rod. Attached Figure Description

[0014] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0015] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: an auxiliary support for optical lens thickness detection, including a base 1, an auxiliary support body 2 fixedly connected to the top of the base 1, an adjustment block 3 slidably connected to the surface of the auxiliary support body 2, an adjustment mechanism 4 installed inside the adjustment block 3, an adjustment column 5 fixedly connected to the front end of the adjustment block 3, a rotating column 6 rotatably connected inside the adjustment column 5, a clamping rod 7 slidably connected inside the rotating column 6, several limiting holes 8 are provided at both ends of the clamping rod 7, arc blocks 9 are fixedly connected to both ends of the adjustment column 5, and adjustment grooves 10 are provided at both ends of the rotating column 6. A round block 11 is slidably connected inside the adjustment groove 10, and a limiting rod 12 is fixedly connected to the side of the round block 11 near the inside of the adjustment groove 10. Specifically: The operator moves the clamping rod 7 to fit the optical lens. After adjusting it to the appropriate position, the operator rotates the rotating column 6. As the rotating column 6 rotates, it causes the round block 11 to contact the thicker end of the arc block 9. This causes the arc block 9 to push the round block 11, which in turn causes the limiting rod 12 to be inserted into the limiting hole 8. This allows the operator to secure the optical lens and also makes it easier to replace the clamping rod 7.

[0016] Reference Figure 3 As shown in this embodiment: guide grooves 13 are provided on both sides of the inside of the adjusting groove 10, and guide blocks 14 are fixedly connected to both sides of the round block 11. The surface of the guide block 14 is slidably connected to the inside of the guide groove 13. Specifically: As the circular block 11 slides along the inside of the adjustment groove 10, the guide block 14 slides synchronously in the guide groove 13. The cooperation between the guide groove 13 and the guide block 14 plays a guiding and limiting role, which can ensure that the circular block 11 slides stably in the adjustment groove 10 without deviation or shaking, thereby ensuring that the limiting rod 12 can be accurately inserted into the limiting hole 8, making the operator's stable operation of the optical lens more reliable.

[0017] Reference Figure 3 As shown, in this embodiment: a storage spring 15 is fixedly connected to the side of the round block 11 near the adjustment groove 10, and the side of the storage spring 15 away from the round block 11 is fixedly connected to the inside of the adjustment groove 10. Specifically: During the sliding process of the circular block 11, the energy storage spring 15 will be compressed or stretched. When it is necessary to release the lock on the clamping rod 7, the energy storage spring 15 will use its own elastic force to push the circular block 11 to slide, so that the limiting rod 12 can be pulled out from the limiting hole 8. This makes the operation more convenient and faster when changing clamping rods 7 of different specifications, and improves work efficiency.

[0018] Reference Figure 3 and Figure 5 As shown in this embodiment: the inner wall of the adjusting column 5 is provided with an annular groove 16, and the outer diameter surface of the rotating column 6 is fixedly connected with an annular block 17, and the surface of the annular block 17 is slidably connected to the inside of the annular groove 16. Specifically: During the rotation of the rotating column 6, the ring block 17 will slide along the annular groove 16. The cooperation between the annular groove 16 and the ring block 17 not only provides a stable track for the rotation of the rotating column 6, ensuring the smoothness of the rotation of the rotating column 6, but also restricts the axial movement of the rotating column 6, preventing the rotating column 6 from shifting up and down during rotation.

[0019] Reference Figure 2 and Figure 3 As shown, in this embodiment: the size of the limiting rod 12 is adapted to the size of the limiting hole 8, and the surface of the limiting rod 12 is inserted into the interior of the limiting hole 8; Specifically: Since the size of the limiting rod 12 is precisely matched with the size of the limiting hole 8, when the round block 11 drives the limiting rod 12 to be inserted into the limiting hole 8, the two can be tightly connected. This tight connection ensures that the clamping rod 7 will not move arbitrarily due to external force during the detection process, thus providing a stable and reliable clamping environment for the optical lens and effectively ensuring the accuracy of thickness detection.

[0020] Reference Figure 5 As shown, in this embodiment: a return spring 18 is fixedly connected to the side of the adjusting column 5 away from the ring block 17, and the side of the return spring 18 away from the inside of the adjusting column 5 is fixedly connected to the ring block 17. Specifically: The reset spring 18 has good elastic properties. When the rotating column 6 rotates and drives the ring block 17 to slide in the annular groove 16, if the ring block 17 is squeezed by an external force, the reset spring 18 will be compressed, generating a reverse elastic force. This elastic force can push the ring block 17 back to its original position after the external force disappears, thereby ensuring that the rotating column 6 can be accurately reset after rotation, and maintaining the stability and reliability of the entire detection auxiliary support structure.

[0021] Working principle: The operator moves the clamping rod 7 to fit the optical lens. After adjusting it to the appropriate position, the operator rotates the rotating column 6. As the rotating column 6 rotates, it drives the round block 11 to contact the thicker end of the arc block 9. This causes the arc block 9 to push the round block 11 to insert the limiting rod 12 into the limiting hole 8, so that the operator can secure the optical lens and easily replace the clamping rod 7.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
