Compensation Method For Angle Error of Hydraulic Unclamping Rotation Axis
At present,most of the rotatable shafts of the horizontal machining center are use of hydraulic unclamp structure.It is found that angle error will be generated after multiple unclamping,which affects the machining accuracy.It is found through repeated inspection with laser interferometer that very small angle error will be generated when unclamping each time,but the error is within the allowable range.With the increase of the number of loose clamps,the angle error will accumulate and affect the accuracy of angle positioning.Through anal-ysis and test,the positioning error is compensated and corrected each time the clamping is loosened by changing the time sequence of loos-ening the clamping,cooperating with the position monitoring and compensation function of the numerical control system,eliminating the error accumulation and improving the positioning accuracy of the rotating axis.
