Abstract

The invention relates to a double-parallel-flexible-hinge-based tool rest driving platform of a super-precision machining lathe and belongs to a tool rest driving platform of a super-precision machining lathe. A tool rest work table, a hinge group and a tool rest mounting base form an integrated structure, the free end of an X-direction piezoelectric actuator is in ejected connection with an X-direction double parallel four bar flexible hinge chain mechanism, the fixed end of the X-direction piezoelectric actuator is fixedly connected with a tool rest mounting base, the free end of a Y-direction piezoelectric actuator is in pressed connection with the tool rest work table, and the fixed end of the Y-direction piezoelectric actuator is fixedly connected with the tool rest mounting base. The double-parallel-flexible-hinge-based tool rest driving platform is a two-dimensional degree-of-freedom micro-displacement platform which is novel and simple in structure and realizes precise control.

Description

technical field [0001] The invention belongs to an ultra-precision machining lathe tool rest driving platform. Background technique [0002] Ultra-precision machining technology is the basis for the development of advanced technologies such as modern aerospace military industry, optoelectronic communication and genetic engineering; it has become a key technology for technology-intensive products such as instrument manufacturing, astronomical telescopes, laser printers, and optical medical instruments. Therefore, people pay more and more attention to precise production equipment and measuring instruments, and the key technology to improve the precision of equipment lies in the micro-displacement feeding technology of the platform. [0003] Piezoelectric ceramic actuators have the advantages of high displacement resolution, fast response, large rigidity, and miniaturization, which overcomes the large inertia, slow response, and complex structure of mechanical, hydraulic, pneum...
