Mechanical arm vibration reduction test device based on camera

Abstract

The invention provides a mechanical arm vibration reduction test device based on a camera. The output shaft of a first stepping motor is sleeved with a motor balance bracket, and the right end of themotor balance bracket is fixedly connected with a connecting arm. A first adjustable weight workpiece is disposed in a first chute located on the left end of the motor balance bracket. The left end ofthe connecting arm is fixedly connected to the right end of the motor balance bracket, and a second stepping motor is connected to the right end of the connecting arm. The left end of a flexible cantilever sleeves the output shaft of the second stepping motor, and the right end of the flexible cantilever is connected with a flat plate. The middle of a camera balance bracket sleeves the output shaft of the second stepping motor, and the right end of the camera balance bracket is provided with a mounting slot. The camera is slidable and positionable on the mounting slot. A second adjustable weight workpiece is disposed in a second chute located on the left end of the camera balance bracket. A piezoelectric sheet is disposed on the side of the flexible cantilever facing the camera. The inputterminals of the camera and a charge amplifier are electrically connected to a controller, and the output of the charge amplifier is electrically connected to the piezoelectric sheet.
