The invention discloses a dual-concave-mirror grinding and polishing upper jig, and belongs to the technical field of dual-concave-mirror grinding and polishing. The dual-concave-mirror grinding and polishing upper jig comprises a clamping head and a connecting body. A circular groove is formed in the top end of the clamping head. The bottom face of the circular groove is provided with an arc-shaped boss. The connecting body is provided with a plurality of jetting airways for making the connecting body communicate with the clamping head. Dual concave mirrors are blown down to a lower end grinding head through the air sprayed of the jetting airways to be directly grabbed by a mechanical hand, the full-automatic production can be realized, and production efficiency is greatly improved. The side wall of the clamping head is evenly provided with a plurality of inclined grooves. A discharge hole is formed in each inclined groove and used for discharging polishing powder on edges, so the aperture local tolerance distortion of the edges of the dual concave mirrors is effectively avoided. Two sealing grooves are formed in the side wall of the connecting block, and a positioning conical groove is formed in the center of the tail end of the connecting block. O-rings are placed in the sealing grooves, and rapid positioning and connecting can be conducted on the O-rings and an external upper shaft
Description
technical field [0001] The invention relates to the technical field of grinding and polishing of double concave mirrors, in particular to an upper jig for grinding and polishing of double concave mirrors. Background technique [0002] In recent years, with the technological progress in the field of opto-mechanical-electrical, various scanners, projectors, digital cameras and other new products have an increasing demand for optical lenses and higher precision requirements. Therefore, continuous improvement of productivity and development of automation is the development theme that the optical cold processing industry must seek. By aligning the center of the ball and adding a professional robot or manipulator to the grinding and polishing machine, the problem of workpiece transfer in each processing cavity can be effectively solved, manpower is liberated, production costs are reduced, and production efficiency is improved. In the grinding and polishing process of spherical le...
