Background technique

As one of the main components of guns such as wild hunting and sports shooting, optical sights determine the accuracy of guns and have a great market demand. Since the development of the domestic optical sight manufacturing industry, its output accounts for 70% of the world's optical sight production and accounts for half of the world's optical sight production. However, my country's optical sight products are generally low-end products with low versatility. It is well known in the industry that when processing parts, various domestic optical sight manufacturers mainly organize multiple general-purpose machine tools, special-purpose machine tools or CNC machine tools to produce in the form of automated or semi-automatic production lines based on the principle of "scattered processes", which requires a relatively large initial period of time. Investment and a large production preparation cycle require more operators at the same time, labor intensity is high, it cannot be adapted to the variability of product orders, and the production line cannot be flexibly adjusted. At the same time, it also affects the further improvement of product quality. The above factors restrict development of the industry.

The current optical sight body processing requires manual operation and is not universally applicable. Therefore, it is urgent to develop an intelligent fixture that can process the entire series of optical sight body bodies to improve production efficiency and quality. and reduce costs. This patent is a special fixture for processing the outer circle of the optical sight mirror body. After searching, no technical solution identical or similar to the present invention has been found.

In order to solve the above technical problems, the technical solution of the present invention is: a special fixture for processing the outer circle of the optical sight mirror body, including a pull rod mechanism, a positioning taper sleeve, an auxiliary unloading mechanism, a tensioning element, a first elastic element, a support rod, The second elastic element and the top, the pull rod mechanism connects the fixture and the main shaft, the tensioning element is arranged in the positioning taper sleeve, the left end of the tensioning element is connected to the auxiliary unloading mechanism, the right end of the tensioning element is connected to the support rod, and the outer wall on the right side of the positioning taper sleeve is provided with The first elastic element is provided with a second elastic element on the outer wall of the right end of the support rod, and the right end of the support rod is connected with the tip.

Further, the pull rod mechanism is threaded to connect the main shaft and the support member, and has a series of sizes and can be replaced.

Further, the auxiliary unloading mechanism is one of rectangular springs, cylindrical springs and the like.

Further, the support rods are of series sizes, and the support rods are replaceable, and can be applied to workpieces of different series sizes.

Further, the first elastic element and the second elastic element are one of metal, rubber, resin and other materials.

Further, the tip is a dedicated tip.

Beneficial effect:

The above-mentioned special fixture for processing the outer circle of the optical sight mirror body realizes the connection between the fixture and the special machine tool spindle through the pull rod mechanism, and realizes the positioning through the positioning taper sleeve. The element generates axial thrust, and at the same time, the support rod generates axial thrust to the elastic element. When the workpiece is positioned, the elastic element slips on the inclined surface and expands and deforms when the workpiece is positioned. Clamp the inner holes at both ends of the scope. After the processing is completed, remove the external force, unload through the auxiliary unloading mechanism, automatically restore under the elastic action of the elastic element, and release the clamping effect of the workpiece.

Detailed ways

The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

As shown in Figure 1, the present invention discloses a special fixture for processing the outer circle of the optical sight mirror body, including a pull rod mechanism 1, a positioning taper sleeve 2, an auxiliary unloading mechanism 3, a tensioning element 4, a first elastic element 5, a support The rod 6, the second elastic element 8 and the top 9, the pull rod mechanism connects the fixture and the main shaft; the tensioning element 4 is arranged in the positioning taper sleeve 2, the left end of the tensioning element 4 is connected to the auxiliary unloading mechanism 3, and the right end of the tensioning element 4 is connected to the support rod 6. A first elastic element 5 is arranged on the outer wall on the right side of the positioning taper sleeve 2, a second elastic element 8 is arranged on the right end of the support rod, and the right end of the support rod 6 is connected with the tip 9. Through the pull rod mechanism 1, the connection between the fixture and the special machine tool spindle is realized, and the positioning is realized through the positioning taper sleeve 2. The special top 9 moves axially under the action of external force, and generates axial thrust on the workpiece 7 and the second elastic element 8. At the same time The support rod 6 generates an axial thrust on the first elastic element 5. When the workpiece is positioned, the first elastic element 5 and the second elastic element 8 slide on the inclined surface when the force is applied to the inclined surfaces at positions A and B. Move, expand and deform, and clamp the inner holes at both ends of the scope body. After the processing is completed, remove the external force, unload through the auxiliary unloading mechanism 3, automatically restore under the elastic action of the first elastic element 5 and the second elastic element 8, and release the clamped state of the workpiece.

As shown in Figure 2, the second elastic element 8 of the present invention is used to clamp the inner circle of the right end of the workpiece 7, and through the cooperation between the top 9 and the oblique surface of the second elastic element 8, an axial F1 and a lateral thrust F2 are generated. After the positioning is realized, the second elastic element 8 is made to slide on the bevel surface, expand and deform, so as to realize the clamping of the eyepiece end of the workpiece 7;

As shown in Figure 3, the first elastic element 5 of the present invention is used to clamp the inner circle of the left end of the workpiece 7. In Figure 2, the axial force of the tip 9 pushes the support rod 6 to move to the left, and the first elastic element 5 is a fixed part , the support rod 6 and the contact surface A of the first elastic element 5 produce relative movement, so that the inclined surface of the first elastic element 5 generates a lateral force F3, so that the first elastic element 5 slips on the inclined surface, and expands and deforms. The workpiece 7 is clamped at the objective lens end.
