The invention discloses a method for compensating radial error and position error of an automatic rope arranging winch and relates to the technical field of methods featured by compensating control devices. The method comprises following steps: calculating the relation of number of turns of a rolling cylinder to radial error and position error in advance before path interpolation of the automatic rope arranging winch; storing the series of compensation values in a rope ranging control system; compensating the rope arranging position once by the rope arranging control system through a spring compensation mechanism at a suspension center when the number of turns of the rolling cylinder changes for one time to make the winch rotate according to a space curve interpolation algorithm and compensate the rope arranging error caused by upper balance wheel position changes and rolling cylinder diameter changes of the automatic rope arranging winch. The method employs the principle of numerical control interpolation to compensate the rope arranging position error and radial error of the automatic rope arranging winch and therefore the rope arranging accuracy is increased and calculation is simple.
Description
technical field [0001] The invention relates to the technical field of a method characterized by a compensating control device, in particular to a compensation method for radial error and position error of a self-draining rope winch. Background technique [0002] Trajectory interpolation is the key technology in the numerical control system. The principle of interpolation on the CNC machine tool is to decompose the basic CNC curve into the minimum amount of movement required to control the movement of the machine tool, that is, to densify the machining trajectory expressed by the CNC program with a large number of coordinate points, and the densification speed is required to be very fast , to improve processing efficiency, and the more interpolation coordinate points, the higher the processing accuracy. The interpolation task is to calculate a number of interpolation points between the starting point and the end point of the curve to be processed according to the given spee...
