Abstract

The invention relates to a clamping control inertia impact motor, and belongs to the technical field of precision driving and positioning. The motor comprises a base, a pair of clamping guide rails, alinear slide rail, a weight balancing mechanism, a mass mechanism, a driving mechanism and a clamping mechanism; the two clamping guide rails are arranged on the base in parallel; the linear slide rail is arranged on the base and is located between the two clamp guide rails; the weight balancing block of the weight balancing mechanism and the mass block of the mass mechanism are arranged on the linear sliding rail in a sliding mode through sliding blocks respectively; the driving mechanism comprises a hollow rhombic driving piece and a driving piezoelectric stack; the clamping mechanism comprises a hollow rhombic clamping piece and a clamping piezoelectric stack; the driving mechanism controls the extension and contraction of a pair of driving feet by utilizing the inverse piezoelectric effect of the driving piezoelectric stack; the clamp mechanism controls the extension and contraction of the pair of clamping feet by utilizing the inverse piezoelectric effect of the clamping piezoelectric stack; the bidirectional linear motion of the piezoelectric motor is realized through the cooperative work of the driving mechanism and the clamping mechanism. Theoretically, the clamping mechanism does not generate sliding friction force, and therefore, energy loss is small.

Description

technical field [0001] The invention belongs to the technical field of precision driving and positioning, and in particular relates to a linear piezoelectric motor. Background technique [0002] Piezoelectric motors use the inverse piezoelectric effect of piezoelectric materials to convert electrical energy into mechanical energy. Due to its small size, large torque, high precision, good low-speed performance, and no electromagnetic interference, it has broad application prospects in the fields of aviation, missiles, robots, and precision instruments. The inertial impact motor is a piezoelectric motion mechanism driven by electrical signals, which has outstanding advantages including large stroke, simple structure, high resolution, miniaturization, and precise positioning. [0003] The inertial impact motor is a motion mechanism that uses the driving force generated by the sudden deformation of the piezoelectric element to overcome the friction force, thereby realizing the ...
