The invention discloses a
machine tool guide rail installation plane parallelism quick
measurement device and method, and the device comprises a sensor installation support and two measurement
system supports, wherein the two measurement
system supports are used for supporting the sensor installation support through leveling ruler sliding rails. The two measurement
system supports are fixed on a
machine tool guide rail installation plane, and the central lines of the two measurement system supports are coincided with the
central line of the sensor installation support. A sliding block is disposed between the sensor installation support and the leveling ruler sliding rails, is fixed with the sensor installation support and drives the sensor installation support to move along the leveling ruler sliding rails. The sensor installation support is provided with electric vortex sensors, and the probes of the electric vortex sensors respectively face a side surface and a bottom surface in the
machine tool guide rail installation plane. The method comprises the steps: support installation, sensor
signal collection, sliding block movement, measurement circulating, and
data processing. The electric vortex sensors are used for collecting data at different positions, and the parallelism error of the
machine tool guide rail installation plane is fit. The device is simple in structure, is simple and convenient to operate, is small in testing result error, and is high in precision.
