Device for moving and positioning piezoresistor of micromotor rotor

The invention relates to a device for moving and positioning a piezoresistor of a micromotor rotor. A feeding mechanism is arranged on a rack and is used for transferring the piezoresistor to a feeding platform; a release mechanism is arranged on the rack and comprises a baffle plate and a second power cylinder; a delivery mechanism comprises a guide part, a guide sliding block, a clamping assembly and a first power cylinder; the clamping assembly along with the guide sliding block is controlled by the first power cylinder to slide along the guide part; the clamping assembly comprises a clamping arm and a clamp arm arranged on the sliding block; a jacking spring is arranged between the clamping arm and the clamp arm; the clamping arm is hinged with the clamp arm through a rotating shaft and swings under control; a pulled end of the clamping arm touches the baffle plate to form a clamping jaw of the clamping arm, and the clamping jaw opens to avoid the piezoresistor; the clamping arm isejected and pressed by t
