Parallel five-axis optical mirror surface processing equipment

Abstract

The invention discloses parallel five-axis optical mirror surface processing equipment. The equipment comprises a processing cutter unit, and a driving mechanism for providing a needed path, processing force and processing gestures to a machining cutter in the optical mirror surface processing process; and the driving mechanism comprises a movable platform, a static platform, five UPS driving branch chains and a UPU constraint branch chain. During working, the five UPS branch chains synchronously drive a cutter frame; and a rotating motion in a Z direction is constrained through the UPU constraint branch chain, so that the translation motion in three directions and the rotating motion in two directions are realized. Meanwhile, a motion detecting and compensating system consisting of multiple sensors can detect and compensate the motion process quantity in real time. The parallel mirror surface processing equipment is high in rigidity and precision and stable in structure, and can meetthe precise processing requirements of large optical mirror surfaces.

Problems solved by technology

[0002] With the rapid development of modern military and aerospace and the continuous breakthrough of advanced manufacturing technology, more and more large optical mirrors have been applied, and the precision requirements are getting higher and higher. However, the traditional manual polishing processing methods and machine tool assistance The traditional manual repairing and polishing method can no longer meet the current application requirements in terms of processing accuracy and processing efficiency.

Existing large-scale optical mirror processing equipment is mostly composed of one or more series-connected robotic arms, and the high rigidity requirements of the equipment in the mirror processing process make the mechanical arms often relatively heavy. At the same time, due to the low positioning accuracy of the serial robotic arms themselves, it is necessary to repeat the " The process of surface shape measurement-grinding and polishing processing seriously affects work efficiency
