Description

Technical Field

[0001] This utility model relates to the field of lens processing and positioning technology, specifically to a positioning fixture for optical sight lenses. Background Technology

[0002] The origins of the scope, or optical aiming device, are difficult to trace. It is said that at least in 16th-century Europe, people had already experimented with attaching spectacle lenses to gunstocks. Written records indicate that before the 19th century, firearms already had telescopic aiming devices for aiming in low-light conditions. Scopes can be categorized into holographic scopes, internal red-green dot sights, and laser sights.

[0003] As disclosed in the patent application CN 221160067 U, an optical sight lens processing positioning fixture includes an outer frame, a tray at the upper end of the outer frame, a cylinder inside the outer frame, and a positioning mechanism on the side of the tray. The bottom of the positioning mechanism cooperates with the cylinder to achieve lens positioning and release. The positioning mechanism includes a fixing part, a positioning component, and a linkage plate. This utility model has a simple structure and reasonable design. By connecting the output end of the cylinder to the linkage plate, and then rotating the linkage plate to the positioning component, a precise linkage mechanism is formed. The entire operation process is relatively simple, easy for operators to operate, and significantly improves work efficiency. In addition, during the positioning process, the positioning part can achieve synchronous positioning of the lens edge, ensuring the accuracy of the processing process, thereby improving the processing quality.

[0004] However, the existing technology CN 221160067 U describes an optical sight lens processing and positioning fixture that does not have a rotating positioning and clamping mechanism. It cannot stably clamp the lens around its perimeter by rotating the screw thread. The single fixing method cannot guarantee the stability of the lens, and it may shift during processing. The entire device is fixed and cannot be rotated, so the user cannot process different positions on the lens. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning fixture for processing optical sight lenses, in order to solve the problems mentioned above, which do not have a rotating positioning clamping mechanism, cannot stably clamp the lens around its perimeter through threaded rotation, cannot guarantee the stability of the lens with a single fixing method, may cause displacement during processing, and the device as a whole is fixed and cannot rotate, so that the user cannot process different positions on the lens.

[0006] To achieve the above objectives, this utility model provides a positioning fixture for processing optical sight lenses.

[0007] The device includes a fixed ring, and a positioning and clamping mechanism is movably arranged around the inside of the fixed ring. The positioning and clamping mechanism includes threaded grooves, a threaded rod, a rotating handle, an arc-shaped clamping block, a bearing, and a placement block. The fixed ring has several threaded grooves inside, and a threaded rod is movably arranged inside the threaded grooves. A rotating handle is fixedly arranged at one end of the threaded rod, and an arc-shaped clamping block is movably arranged at the end of the threaded rod away from the rotating handle. A bearing is fixedly arranged inside the arc-shaped clamping block near the threaded rod, and the bearing is movably connected to the threaded rod. A placement block is fixedly arranged at the bottom end of the arc-shaped clamping block away from the threaded rod.

[0008] The fixed ring has a support platform fixedly installed at its bottom end, and a fixed block fixedly installed at the center of the top end of the support platform. The support platform is used to support the fixed ring, and the fixed block is used to support the telescopic block.

[0009] The fixed block contains a telescopic spring, which in turn contains a damper. A telescopic stop is movably mounted on the top of the telescopic spring. The bottom of the telescopic stop is fixedly connected to the damper and circumferentially connected to the inside of the fixed block. The telescopic stop contacts the bottom of the fixed lens, providing auxiliary support. With the cooperation of the damper and the telescopic spring, shock absorption and buffering are achieved, ensuring that the lens will not shatter due to excessive pressure during processing.

[0010] The support platform has a rotating column movably installed at its bottom end, and a support base is installed on the other side of the rotating column. The support base has several threaded holes around its circumference. By rotating the rotating column, the lens on the support platform can be adjusted in multiple directions.

[0011] The support platform has two grooves on its outer sides, and two connecting columns are movably arranged inside the grooves. The grooves are designed to support the connecting columns, and the movable adjustment of the connecting columns can realize the rotation of the fixed plate.

[0012] The connecting column has a fixed plate movably mounted on one side, and a positioning screw movably mounted on the bottom side of the fixed plate. The positioning screw is movably connected to the threaded hole. The fixed plate can be adjusted so that its bottom side fits into the threaded hole. The positioning screw is rotated to fix the plate, which can ensure the stability of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This is a positioning fixture for processing optical sight lenses. The device first places the optical sight lens to be processed inside a fixing ring, which is then mounted on top of a placement block. The user can adjust the fixing position according to the size of the lens. Manually rotating the handle drives the threaded rod to rotate. Since the threaded rod is engaged with a threaded groove, rotating it left and right allows for telescopic movement. Because one end of the threaded rod is movably connected to the inner ring of a bearing, and the bearing is installed inside an arc-shaped clamping block, rotating the threaded rod will not cause the arc-shaped clamping block to rotate, but will only cause it to shift to one side. Finally, fine adjustments are made in all four directions to achieve stable clamping. The telescopic stop block contacts the bottom of the fixed lens, providing auxiliary support. With the cooperation of a damper and a telescopic spring, shock absorption and buffering are provided to ensure that the lens will not break due to excessive pressure during processing. This device has a rotary positioning clamping mechanism, which can stably clamp the lens from all sides through threaded rotation. Multi-angle clamping ensures the stability of the lens and prevents displacement during processing.

[0015] 2. This optical sight lens processing and positioning fixture allows the user to manually rotate the support platform to reach the designated position. The bottom end of the movable fixing plate inside the groove is aligned with the corresponding threaded hole, and finally, the positioning screw is used to rotate and fix it. The entire device can be rotated and adjusted, making it convenient for the user to process different positions of the lens, which greatly improves the practical value of the device.

[0024] Please see Figures 1-6 As shown, this utility model provides a technical solution:

[0025] An optical sight lens processing and positioning fixture includes a fixed ring 1. A positioning and clamping mechanism is movably arranged around the fixed ring 1. The positioning and clamping mechanism includes threaded grooves 2, threaded rods 3, rotating handles 4, arc-shaped clamping blocks 5, bearings 6, and placement blocks 7. The fixed ring 1 has several threaded grooves 2 inside. The threaded rods 3 are movably arranged inside the threaded grooves 2. The rotating handle 4 is fixedly arranged at one end of the threaded rod 3. The arc-shaped clamping block 5 is movably arranged at the end of the threaded rod 3 away from the rotating handle 4. The bearing 6 is fixedly arranged inside the arc-shaped clamping block 5 near the threaded rod 3. The bearing 6 is movably connected to the threaded rod 3. The placement block 7 is fixedly arranged at the bottom end of the arc-shaped clamping block 5 away from the threaded rod 3.

[0026] In this embodiment, preferably, a support platform 8 is fixedly provided at the bottom end of the fixed ring 1, and a fixed block 9 is fixedly provided at the center of the top end of the support platform 8. The support platform is set to support the fixed ring, and the fixed block is set to bear the telescopic block.

[0027] In this embodiment, preferably, a telescopic spring 10 is fixedly installed inside the fixing block 9, a damper 11 is fixedly installed inside the telescopic spring 10, a telescopic stop block 12 is movably installed at the top of the telescopic spring 10, the bottom end of the telescopic stop block 12 is fixedly connected to the damper 11, and the bottom end of the telescopic stop block 12 is circumferentially connected to the inside of the fixing block 9. The telescopic stop block contacts the bottom end of the fixed lens, providing auxiliary support. With the cooperation of the damper and the telescopic spring, shock absorption and buffering are performed to ensure that the lens will not break due to excessive pressure during processing.

[0028] In this embodiment, preferably, a rotating column 13 is movably provided at the bottom of the support platform 8, and a support base 14 is provided on the other side of the rotating column 13. The support base 14 has several threaded holes 15 circumferentially opened inside. By rotating the rotating column, the lens on the support platform can be adjusted in multiple directions.

[0029] In this embodiment, preferably, two grooves 16 are provided on both sides of the outer side of the support platform 8, and two connecting columns 17 are movably arranged inside the grooves 16. The grooves are designed to support the connecting columns, and the connecting columns can be adjusted to achieve the rotation of the fixed plate.

[0030] In this embodiment, preferably, a fixing plate 18 is movably provided on one side of the connecting column 17, and a positioning screw 19 is movably provided on one side of the bottom end of the fixing plate 18. The positioning screw 19 is movably connected to the threaded hole 15. The fixing plate is movably adjusted so that one side of its bottom end fits into the threaded hole. The stability of the device can be ensured by rotating and fixing it with the positioning screw.

[0031] Example 1: The device first places the optical sight lens to be processed into the fixing ring 1 and mounts it on the top of the placement block 7. At this time, the user can adjust the fixing position according to the size of the lens. The user manually rotates the rotating handle 4 to drive the threaded rod 3 to rotate. Since the threaded rod 3 is engaged with the threaded groove 2, the threaded rod 3 can be extended and retracted by rotating it left and right. Because one end of the threaded rod 3 is movably connected to the inner ring of the bearing 6 and the bearing 6 is installed inside the arc-shaped clamping block 5, the rotation of the threaded rod 3 will not cause the arc-shaped clamping block 5 to rotate, but will only make it move to one side. Finally, it is finely adjusted in four directions to achieve stable clamping. The telescopic block 12 contacts the bottom end of the fixed lens to provide auxiliary support. The damper 11 and the telescopic spring 10 work together to provide shock absorption and buffering.

[0032] Example 2: If it is necessary to change the lens processing point, the user can manually rotate the support platform 8 to the designated position, align the bottom end of the fixed plate 18 that is movably set inside the groove 16 with the corresponding threaded hole 15, and finally use the positioning screw 19 to rotate and fix it.

[0033] In this embodiment, an optical sight lens processing and positioning fixture is used. First, the optical sight lens to be processed is placed inside the fixing ring 1 and mounted on the top of the placement block 7. The user can adjust the fixing position according to the size of the lens. Manually rotating the handle 4 drives the threaded rod 3 to rotate. Since the threaded rod 3 is engaged with the threaded groove 2, it can extend and retract by rotating left and right. Because one end of the threaded rod 3 is movably connected to the inner ring of the bearing 6, and the bearing 6 is installed inside the arc-shaped clamping block 5, the rotation of the threaded rod 3 will not cause the arc-shaped clamping block 5 to rotate, but will only cause it to shift to one side. Finally, fine adjustments are made in all four directions to achieve stable clamping. The telescopic stop block 12 contacts the bottom end of the fixed lens, providing auxiliary support. The damper 11 and the telescopic spring 1... With the cooperation of 0, shock absorption and buffering are provided to ensure that the lens will not break due to excessive pressure during processing. If it is necessary to change the lens processing point, the user can manually rotate the support table 8 to the designated position, and then align the bottom end of the fixed plate 18, which is movably set inside the groove 16, with the corresponding threaded hole 15. Finally, the positioning screw 19 is used to rotate and fix it. The device has a rotary positioning and clamping mechanism, which can stably clamp the lens around its perimeter through threaded rotation. The multi-angle clamping ensures the stability of the lens and prevents it from shifting during processing. The elastic buffer structure set at the bottom of the lens can prevent the lens from breaking due to excessive pressure during processing. The entire device can be rotated and adjusted, which makes it convenient for the user to process different positions of the lens, greatly improving the practical value of the device.
