Abstract

The invention relates to optical precision instrument detection equipment and method, in particular to a cylinder and cylindrical surface trough line precision detection device and method based on projection track recovery, and aims to solve the problems that an existing cylindrical surface trough line precision detection method is complex in operation, low in intelligent degree, low in efficiency, unstable in test precision and poor in detection precision. And therefore, the high-precision and batch detection requirements cannot be met. The cylinder cylindrical surface groove line precision detection device based on projection track restoration comprises an annular rotary table, a marking plate, a marking pen, a translation table and an adjusting assembly. According to the invention, the marking pen is used as a leading point of the cylindrical trough line to perform track recovery on the cylindrical trough line on the marking plate, so that the effects of automatic intelligent operation and whole-course stable test can be realized, and the high-precision detection requirements of various optical loads on the cylindrical trough line can be met. Meanwhile, the invention discloses a cylinder and cylindrical surface groove line precision detection method based on projection track recovery.

Description

technical field [0001] The invention relates to detection equipment and methods for optical precision instruments, in particular to a detection device and detection method for the accuracy of cylindrical groove lines based on projection trajectory restoration. Background technique [0002] With the increasing demand for imaging on the ground and in the aviation and aerospace fields, the research and development of precision optical payloads for imaging is becoming more and more urgent. In order to meet the requirements of the field of view change of the precision optical load, the interval between some optical components must be adjusted accurately. The cylindrical groove line drives the guide post to drive the movement of the optical components to meet the high integration and high precision of the precision optical load system. A common innovative application method required. [0003] The machining of the cylindrical groove line needs to be designed according to the techn...
