WORKING MACHINE AND POSITIONAL DEVIATION DATA ACQUISITION METHOD

摘要

In a work machine which includes: a working head 24 including (a) a lifting and lowering unit 34 including a working device 28 and a first lifting and lowering device 30 which lifts and lowers the working device, and (b) a second lifting and lowering device 36 which lifts and lowers the lifting and lowering unit, a positional deviation (”x, ”y) of the working device in a direction which is perpendicular to a lifting and lowering direction is eliminated. Since the positional deviation is caused by both an inclination of a lifting and lowering axis line L 1 of the working device by the first lifting and lowering device and an inclination of a lifting and lowering axis line L 2 of the lifting and lowering unit by the second lifting and lowering device, based on positional deviation data which is associated with both a lifted and lowered position of the working device and a lifted and lowered position of the lifting and lowering unit, a target moving position when the working head moves in the perpendicular direction by a head moving device is corrected. By performing correction in this manner, the positional deviation is eliminated, and accurate work can be performed.
