Description

technical field [0001] The invention relates to a two-dimensional constant force hanging device. Background technique [0002] The two-dimensional motion constant force hanging device realizes vertical constant force hanging and horizontal movement following of the target workpiece, without introducing other external forces to the target workpiece, and does not affect the motion state of the target workpiece. In the prior art, a suspension rope is usually used to connect the slider of the linear guide rail to the target workpiece, the angle sensor is used to measure the deflection angle of the suspension rope, the movement of the slider is controlled by a motor to follow the movement in the horizontal direction, and then the force sensor is used to measure the deflection angle of the suspension rope. The size of the force on the suspension rope, by tightening or loosening the suspension rope, the follow-up and constant force output in the vertical direction can be realized. ...
