Abstract

The invention discloses a long-stroke fast tool servo device. The long-stroke fast tool servo device comprises a machine frame, a piezoelectric ceramic driver which is arranged on the machine frame and can achieve axial telescoping, an input block which abuts against the tail end of the piezoelectric ceramic driver and is driven by the piezoelectric ceramic driver to make linear movement, a tool rest used for mounting a tool, and a displacement magnification mechanism which is connected between the input block and the tool rest and used for magnifying and transferring the displacement of the piezoelectric ceramic driver to the tool rest. The overall structure of the displacement magnification mechanism is symmetrical by using the piezoelectric ceramic driver as the axis of symmetry. According to the long-stroke fast tool servo device disclosed by the invention, the piezoelectric ceramic driver is used for driving the tool to make displacement, and high displacement accuracy is guaranteed; meanwhile, the displacement of the piezoelectric ceramic driver is increased through the displacement magnification mechanism, so that the tool has a large displacement stroke; and the influence factors on the axial displacement of the tool are removed through the axisymmetric structure of the displacement magnification mechanism, and the displacement accuracy of the tool under the long-stroke condition is further improved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a long-stroke fast tool servo device. 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, using Fast Tool Servo (FTS, FastTool Servo) technology to process free-form optical components is considered to be the most promising processing method. [0003] The cutting force generated during the turning process wil...
