Abstract

The invention relates to a quick cutter servo device with two decoupled shafts, and belongs to the technical field of cutting machining of optical curved surface parts and ultraprecise parts. A diamond cutter is fixedly connected with a cutter seat on a flexible hinge base body through a fixing screw, and the two ends of an X-axis piezoelectric stack are connected with the flexible hinge base body and an X-axis driving end respectively. The X-axis piezoelectric stack is connected with the flexible hinge base body through a first pre-tightening bolt, and a first Z-axis piezoelectric stack and a second Z-axis piezoelectric stack are connected with the flexible hinge base body and a Z-axis piezoelectric stack respectively. A displacement detection block is mounted behind the cutter seat on the flexible hinge base body, and the displacement detection block is fixedly connected with the flexible hinge base body through a fixing screw. The quick cutter servo device with the two decoupled shafts has the advantages that the structure is novel, the mode that a piezoelectric actuator is in parallel connection with a flexible mechanism is used, the inertia mass of the movement part of a flexible hinge mechanism is reduced, the operation bandwidth of an FTS device can be better increased, and the machining efficiency of the FTS device is improved.

Description

technical field [0001] The invention belongs to the technical field of cutting processing of optical curved surface parts and ultra-precision parts, and relates to a two-axis decoupling fast tool servo device for free-form surface diamond turning. Background technique [0002] Free-form optical components are not only widely used in optoelectronic products and optical communication products, but also widely used in military fields such as infrared detection equipment and helmet-mounted displays. In addition, in view of the fact that many non-free-form optical elements can be obtained by using fewer free-form optical elements to realize the function, simplify the structure of the optical system and reduce the quality and volume of the optical system, which is very important for the integration and miniaturization of the optical system. is of great significance. Although the optical free-form surface has many excellent properties and uses mentioned above, the complexity and u...
