Two-dimensional constant force following hanging device

Abstract

A two-dimensional constant force following hanging device comprises a constant force output air cylinder, an air floatation guide rail, air floatation cushions, a linear guide rail, a motor, a laser displacement sensor, a reflector, a support and the like. The air floatation guide rail comprises a first air floatation sleeve, second air floatation sleeves, a first air floatation shaft and a second air floatation shaft. The linear guide rail is parallel to the second air floatation shaft, and the linear guide rail and the second air floatation shaft are vertically installed on the support. The linear guide rail is sleeved with a sliding block which is connected with a fixing plate. The constant force output air cylinder is vertically installed on the fixing plate, the number of the second air floatation sleeves is two, and the second air floatation shaft is sleeved with the second air floatation sleeves which are connected through an installing plate. The first air floatation shaft is sleeved with the first air floatation sleeve. The two ends of the first air floatation shafts are respectively fixedly connected with a cylinder barrel of the constant force output air cylinder and the installing plate on the second air floatation sleeves, and the first air floatation sleeve is connected with a target workpiece through a hanging rope. According to the two-dimensional constant force following hanging device, long-distance constant force hanging is achieved through the constant force output air cylinder, horizontal following is achieved through the air floatation guide rail, two-dimensional constant force hanging accuracy is high, and stability is good.

Description

technical field [0001] The invention relates to a two-dimensional constant force hanging device. Background technique [0002] The two-dimensional constant force following hanging device realizes vertical constant force hanging and horizontal motion 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....
