Abstract

The invention discloses a fast knife servo system with constant force output, which comprises a driving mechanism, a flexible leaf spring positive stiffness mechanism, a flexible leaf spring negative stiffness mechanism, a fixed base, a connecting piece, a knife holder and a knife; the driving mechanism is installed in the fixed base , the power output shaft of the drive mechanism is connected to the center of the negative stiffness mechanism of the flexible leaf spring; the center of the negative stiffness mechanism of the flexible leaf spring is connected to the center of the positive stiffness mechanism of the flexible leaf spring through a first connecting piece , the outer ring of the flexible leaf spring negative stiffness mechanism is connected to the outer ring of the flexible leaf spring positive stiffness mechanism through the second connecting piece, and the flexible leaf spring negative stiffness mechanism and the flexible leaf spring positive stiffness mechanism are fixed on the On the base; a knife rest is installed at the center of the positive stiffness mechanism of the flexible leaf spring, and a knife is installed on the knife rest.

Description

technical field [0001] The invention relates to a fast-knife servo system, in particular to a fast-knife servo system with constant output force and adjustable constant force. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Microstructure arrays, diffractive elements, non-circular cross-section parts and other new complex curved surface parts and microstructure optical elements are more and more widely used. For such parts / components with complex surface shapes, traditional processing methods are incompetent, and ultra-precision fast tool servo, referred to as fast tool servo technology, is currently the key technology for processing such complex curved surface parts. [0004] Fast tool servo technology is to install a fast servo unit on the CNC machine tool to change the axial or radial feed rate in real time with high frequency and high precisio...
