Abstract

The invention discloses an inchworm bionic device which aims to solve the problems that in the prior art, an existing inchworm bionic device is large in size, low in positioning accuracy, difficult to process, high in requirement for the working environment, large in friction and small in route and has a single degree of freedom. The inchworm bionic device comprises a first supporting part, a fourth piezoelectric stack, a second supporting part, a third supporting part, a first direction control part, a fifth piezoelectric stack and a second direction control part. The right end of the second supporting part is fixedly connected with a screw at the left end of the fifth piezoelectric stack. The right end of the fifth piezoelectric stack is fixedly connected with a screw at the left end of the first direction control part. The right end of the first direction control part is fixedly connected with a screw at the left end of the third supporting part. The left end of the second supporting part is fixedly connected with a screw at the right end of the fourth piezoelectric stack. The left end of the fourth piezoelectric stack is fixedly connected with a screw at the right end of the second direction control part. The left end of the second direction control part is fixedly connected with the right end of the first supporting part.

Description

technical field [0001] The invention relates to a mobile device in the field of micro mobile devices, more precisely, the invention relates to an inchworm bionic device. Background technique [0002] With the deepening of human research on the microscopic field, especially in the fields of ultra-precision machining and micro-robots, the requirements for device miniaturization and precise displacement are getting higher and higher. Traditional driving methods such as motor drive, electromagnetic drive and other macroscopic large-scale The drive unit can no longer meet its requirements. At present, the piezoelectric actuator has been widely researched and applied due to its advantages of small size and high precision, but many problems have not been really solved. The traditional crawling bionic inchworm piezoelectric actuator provides friction through the clamping mechanism. The working environment and the inner diameter of the working pipe are demanding, so it cannot be wid...
