Tiny clamp capable of integrating clamping force sensor and clamping jaw displacement sensor

Abstract

The invention relates to a tiny clamp capable of integrating a clamping force sensor and a clamping jaw displacement sensor and aims to solve the problems in the prior art that the tiny clamp cannot simultaneously measure the clamping force and the displacement of a clamping jaw and cannot ensure that the clamping jaw moves in parallel. According to the technical scheme, the tiny clamp comprises abase, a single-piece flexible mechanism fixed on the base, an actuator mounted in a cavity formed in the single-piece flexible mechanism, a controller, a strain demodulator connected with the controller, and the clamping force sensor and the clamping jaw displacement sensor connected with the strain demodulator, wherein the single-piece flexible mechanism comprises a displacement amplifying mechanism, two symmetrical clamping force sensing mechanisms and two symmetrical clamping jaws; the input stage of the displacement amplifying mechanism is connected with the actuator in a propped manner;the two output stages of the displacement amplifying mechanism, the two clamping force sensing mechanisms and the two clamping jaws are in one-to-one correspondence; and the output stages of the displacement amplifying mechanism, the clamping force sensing mechanisms and the clamping jaws are sequentially connected.

Description
