Abstract

The invention discloses a modularized six-freedom-degree precision inching mechanism based on a flexible hinge. The modularized six-freedom-degree precision inching mechanism comprises a first original driving block, an output frame, a second original driving block, third original driving blocks, a fixed panel and an installation panel; the inching mechanism is driven by a piezoelectric system, and the piezoelectric driving system comprises a signal generator, a power amplifier and piezoelectric ceramic; the signal generator generates a signal source, an output signal of the signal generator is amplified through the power amplifier, accordingly, the piezoelectric ceramic is promoted to conduct linear displacement, and moreover, the piezoelectric ceramic pushes the flexible hinge so that all-around displacement of the inching mechanism can be achieved; and the first original driving block, the second original driving block and the third original driving blocks are each formed by vertically arranging a parallelogram structure composed of straight girder hinges.

Description

technical field [0001] The invention relates to the technical field of vibration-assisted processing, in particular to a modular six-degree-of-freedom precision micro-motion mechanism based on a flexible hinge. Background technique [0002] Vibration-assisted machining technology is a technology that uses numerical control machining technology and vibration devices to process parts with complex micro-sized shapes such as micro-structured surfaces. Different from the traditional processing technology, vibration-assisted processing generates a processing strategy according to the surface characteristics of the machined surface, that is, establishes the feed motion of the tool and the workpiece, and disassembles it into the control part of the CNC machine tool according to the change frequency and size of the feed motion curve. The control part of the micro-motion device. The part with large feed amount or relatively low frequency change is realized by numerical control machin...
