The embodiment of the invention discloses a parallel-connection translational three-dimensional rapid servo device of a numerical control ultraprecision processing machine tool, and aims to solve the technical problems of a traditional FTS device that machining cost is high; machining efficiency is low; multi-degree of freedom displacement error compensation cannot be realized; and absolute rigidity in other directions cannot be ensured. The parallel-connection translational three-dimensional rapid servo device comprises an X-direction driving platform, a Y-direction driving platform, a Z-direction driving platform, main flexible hinges, a subsidiary flexible hinge and a tool, wherein the X-direction driving platform and the Y-direction driving platform are connected with the tool through the main flexible hinges; and the Z-direction driving platform is connected with the tool through the subsidiary flexible hinge.
Description
technical field [0001] The invention relates to the field of free-form surface optical elements, in particular to a parallel translational three-dimensional fast tool servo device of a numerical control ultra-precision machining machine tool. Background technique [0002] Freeform surface optical components have significant advantages such as improving optical performance, optimizing product structure, and realizing light weight. With the rapid development of modern science and technology, the application fields of free-form optical components are gradually expanding, including not only core technical fields such as aviation, aerospace, national defense, and military affairs, but also daily life such as ordinary civilian use and office work. It is also widely used in medical optical cameras, scanners, infrared night vision devices and other fields. Among them, the processing of free-form optical elements by using fast tool servo (FTS) technology is considered to be the most...
