Abstract

A two-dimensional motion constant force hanging device comprises constant force output air cylinders, an air floatation guide rail, linear guide rails, a motor, laser displacement sensors, a support and the like. The air floatation guide rail comprises an air floatation sleeve and an air flotation shaft, the linear guide rails are vertically installed on the support, two sets of parallel linear guide rails are arranged, the number of the constant force output air cylinders is two, the two ends of cylinder tubes of the constant force output air cylinders are arranged on the linear guide rails in a sleeved mode through sliders respectively, output shafts of the constant force output air cylinders are connected with the air floatation shaft through connecting devices, the air floatation shaft is sleeved with the air floatation sleeve, the air floatation sleeve is connected with a target workpiece through a hanging rope, the motor can drive the sliders to move, and the laser displacement sensors are installed on limiting blocks. The two-dimensional motion constant force hanging device achieves constant force hanging through the constant force output air cylinders, horizontal following is achieved through the air floatation guide rail, and the two-dimensional motion constant force hanging device is high in precision and good in stability.

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. ...
