摘要: Spindle inclination detectors (41A, 41B) are equipped in columns (32A, 32B) of a portal bridge (24) of a machine tool (21). Each spindle inclination detector includes: a string (43) which hangs vertically with an upper end fixed to the column (reinforcement (32b)) and a lower end attached to a weight (45); a gap sensor (44) which is attached to the string to measure a distance to a front face plate (32a) of the column; and an oil damper (46). Moreover, a spindle inclination correction controller provided to the machine tool controls a Peltier device (42A, 42B) attached to a rear face plate (32d) of the column, on a basis of an average distance measured by the gap sensor, and thus corrects an inclination of a spindle (28) due to the thermal deformation of the column by correcting thermal deformation of the column.

摘要: An object of the present invention is to provide: a spindle inclination detector capable of surely detecting spindle inclination with a simple configuration; and a machine tool including the spindle inclination detector. Spindle inclination detectors (41A, 41B) are equipped in columns (32A, 32B) of a portal bridge (24) of a machine tool (21). Each spindle inclination detector includes: a string (43) which hangs vertically with an upper end fixed to the column (reinforcement (32b)) and a lower end attached to a weight (45); a gap sensor (44) which is attached to the string to measure a distance to a front face plate (32a) of the column; and an oil damper (46). Moreover, a spindle inclination correction controller provided to the machine tool controls a Peltier device (42A,42B) attached to a rear face plate (32d) of the column, on a basis of an average distance measured by the gap sensor, and thus corrects an inclination of a spindle (28) due to the thermal deformation of the column by correcting thermal deformation of the column.
