Description

Technical Field

[0001] The utility model relates to the technical field of sight mirror processing, in particular to a sight mirror processing positioning tool. Background Art

[0002] The origin of the sight, or optical aiming device, is difficult to verify. It is said that at least in Europe in the 16th century, people had tried to fix eyeglass lenses on the butt of a gun. There are written records that before the 19th century, firearms had telescopic aiming devices that could be used for aiming in low light conditions. The sight can be divided into holographic sights, internal red and green dot sights, and laser sights.

[0003] Positioning tooling is required during the production and processing of sight lenses.

[0004] The existing sight processing and positioning tooling cannot quickly and accurately clamp and fix the sight lens during processing and positioning. It is necessary to manually move the lens repeatedly to locate its center point and then fix it for processing, which is inefficient and inconvenient to use. Utility Model Content

[0005] The utility model aims to provide a sighting mirror processing and positioning tool, which has the characteristics of fast and accurate clamping and fixing of the sighting mirror lens and is easy to use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a kind of sight processing and positioning tooling, comprising a workbench, the lower end surface of the workbench is fixedly connected to a mounting box, the upper end surface of the workbench is penetrated by a through hole connected to the mounting box, the lower end surface of the mounting box is installed with a telescopic cylinder, the output end of the telescopic cylinder extends to the inside of the through hole and is fixedly connected to a placement table, the outer wall of the output end of the telescopic cylinder is fixedly connected to a plurality of evenly distributed connecting blocks, the interiors of the plurality of connecting blocks are rotatably connected to connecting rods, and the other end of the connecting rod is rotatably connected to a clamping block located above the placement table.

[0007] In order to keep the clamping block in a horizontal state at all times, as a preferred tooling for machining and positioning a sight of the utility model, a pull rod located between a plurality of connecting rods is rotatably connected between the connecting block and the clamping block.

[0008] In order to pull the connecting rod outward, as a preferred tooling for machining and positioning a sight of the utility model, a tension spring is movably connected between the connecting block and the connecting rod via a fixing plate.

[0009] In order to reduce the degree of wear of the connecting rod, as a preferred tooling for processing and positioning a sight of the utility model, the inner wall of the through hole is provided with a plurality of evenly distributed grooves, and the interiors of the plurality of grooves are rotatably connected with rollers that abut against the connecting rod.

[0010] In order to prevent the clamping blocks from damaging the sighting lens, as a preferred tooling for machining and positioning the sighting lens of the utility model, one side wall opposite to each other of the plurality of clamping blocks is fixedly connected with a protective cushion.

[0011] In order to facilitate the multiple clamping blocks to clamp and fix the circular sighting lens, as a preferred sighting lens processing and positioning tool of the utility model, the multiple clamping blocks are all arranged in an arc structure and form a circular ring structure.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The telescopic cylinder drives the placement table to move downward, and at the same time, the output end of the telescopic cylinder drives the multiple connection blocks, the multiple connection rods and the multiple clamping blocks to move downward. Through the mutual cooperation between the multiple connection rods and the through holes, the multiple connection rods can be moved inward, and then the multiple clamping blocks can be moved close to each other, so as to clamp and fix the aiming lens;

[0014] By moving the multiple clamping blocks in opposite directions by the same distance, the center point of the circle formed by the multiple clamping blocks can be fixed, and then the center point of the aiming lens can be accurately and quickly positioned through the multiple clamping blocks, which is easy to use.
