Abstract

The invention provides a long-distance two-dimensional following constant force hoisting device. The device comprises a constant force output air cylinder, an air flotation device, a guide rail system, a pulley block, a rope winding motor, a suspension rope, a detection device and the like, wherein the guide rail system comprises a linear guide rail, a sliding block and a motor, the linear guide rail is sleeved with the sliding block, the motor can drive the sliding block to move, the air flotation device is connected with the sliding block, a first fixed pulley and a second fixed pulley are connected with the air flotation device, one end of the suspension rope is fixed, the other end of the suspension rope sequentially penetrates through the first fixed pulley, a movable pulley and the second fixed pulley to be connected with the rope winding motor, the movable pulley is connected with the constant force output air cylinder through a movable pulley base, and a piston rod of the constant force output air cylinder penetrates through a cylinder barrel cover to lift a target workpiece. The constant force lifting in the vertical direction can be achieved through the constant force output air cylinder, the ultra long following in the vertical direction can be achieved through the detection device, the pulley block and the rope winding motor, the horizontal following can be achieved through the pulley block and the air flotation device, the stability is good, and the precision is high.

Description

technical field [0001] The invention relates to a two-dimensional constant force hanging device. Background technique [0002] The two-dimensional 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. Howeve...
