Abstract

The invention provides an inertia stick-slip cross-scale motion platform capable of achieving unidirectional movement. A balancing weight, a piezoelectric ceramic actuator and a principle mass block are combined, and when forward or backward voltage is applied between the positive electrode and negative electrode of the piezoelectric ceramic actuator, the piezoelectric ceramic actuator stretches or contracts slightly in the length direction and drives the balancing weight and principle mass block to move, so that millimeter-level stroke and nanometer-level positioning precision are realized. Compared with other motion platforms, the inertia stick-slip cross-scale motion platform has the advantages that the structure is simple, quick large-stroke precise positioning can be achieved, multi-freedom-degree driving can be achieved easily, and a special position retaining device is not needed.

Description

technical field [0001] The invention belongs to the technical field of precision motion, and in particular relates to an inertial stick-slip cross-scale motion platform for realizing one-way motion. Background technique [0002] With the rapid development of micro / nano technology, there is an urgent need for sub / micron, micro / Nanoscale ultra-precise drive mechanism. [0003] Cross-scale precision motion technology with nanometer-level motion resolution and millimeter-level motion travel is the key technology in the field of micro-drives. Compared with other cross-scale motion driving methods, the inertial stick-slip drive has simple driving principle, convenience, and simple control, and has the advantages of large motion range, high resolution, simple structure, easy miniaturization, and precise positioning, so the inertial stick-slip Driving is a method that is widely used in the current cross-scale driving. The working principle of inertial stick-slip drive is mainly ...
