Polar coordinate type sub-lens module assembling and disassembling device for spliced optical telescope

Abstract

The invention discloses a polar coordinate type sub-lens module assembly and disassembly device for a spliced optical telescope, and belongs to the technical field of maintenance of large optical telescopes. The device comprises a long bridge leading-in system, a long bridge assembly body and an annular guide rail system. The long bridge leading-in system comprises a longitudinal beam capable of sliding, and a cross beam capable of sliding and carrying a long bridge assembly body is arranged on the longitudinal beam so as to improve the sliding stroke; the annular guide rail system comprises an outer ring rail and an inner ring rail which are coaxial with the optical telescope. The two ends of the long bridge assembly body can move along the outer ring rail and the inner ring rail respectively. A long bridge vertical guide rail plate capable of horizontally sliding is arranged on the long bridge assembly body, a bridge vertical device connecting piece capable of ascending and descending is arranged on the long bridge vertical guide rail plate, and a rotatable six-degree-of-freedom mechanism is arranged below the long bridge vertical device connecting piece and comprises a movable platform capable of moving at six degrees of freedom; a clamping mechanism is arranged at the lower end of the movable platform to clamp the sub-mirror so as to complete disassembly and assembly of the sub-mirror.
