Abstract

The invention discloses a centering type locking mechanism based on piezoelectric motor drive and relates to the technical field of automatic clamping mechanism equipment of machine tools or machining centers. The centering type locking mechanism aims at solving the problems that an existing electromagnetic motor drive type locking mechanism is complex in structure, and electromagnetic interference exists. According to the centering type locking mechanism, a clamp and clamping claws are hinged through bolts, limiting plates are connected with the top ends of side walls of the clamp, a wedge head driving shaft penetrates through two output shaft sleeves, one output shaft sleeve is connected with the center of the bottom surface of the clamp to be fixed, the other output shaft sleeve is connected with a motor fixing plate, a wedge head of the wedge head driving shaft is connected with the bottom ends of the four clamping claws, two driving feet of a piezoelectric motor are connected with the output shaft sleeves, forward voltage and backward voltage are applied to all piezoelectric ceramic pieces on the piezoelectric motor, reciprocating motion of the wedge head driving shaft is controlled by controlling the timing sequence of applying the voltage to the piezoelectric ceramic pieces, and thus the locking and unlocking functions of the locking mechanism are achieved. The centering type locking mechanism can be applied to manufacturing of automatic locking mechanism equipment of numerical control machine tools or machining centers.

Description

technical field [0001] The invention relates to the application of piezoelectric motor drive to a centering locking mechanism, and relates to the technical field of automatic clamping mechanism equipment for machine tools and machining centers. Background technique [0002] The centering locking mechanism is often used in the fixture design of various machine tools and machining centers, and its most basic function is to position and clamp the workpiece during the workpiece processing. In order to realize the automatic processing process, it is necessary to equip the locking mechanism with a power source to realize the automatic locking process. At present, the mature automatic locking mechanism adopts rotating electromagnetic motor as the driving element. Since the output motion of the electromagnetic motor is rotary motion, the speed is high and the output is small, it generally needs to cooperate with the reducer and transmission mechanism to realize deceleration, force i...
