The application discloses a gantry
machine tool wall parallelism measurement method and
system, and the method comprises the following steps:
processing a plurality of groups of corresponding measurement surfaces on the two side walls of the gantry
machine tool;
processing a taper hole on one side of each group of measurement surfaces; adjusting the depth of a half-ball head screw inserted into a hanging
pipe and the length of a dial gauge inserted into a connecting rod, so that the total length between the free end of the half-ball head screw and the measurement head of the dial gauge is adapted to the distance between the walls of the gantry
machine tool; suspending the measurement
system between the two walls of the gantry
machine tool; tightly abutting the ball head of the half-ball head screw on the taper hole of the wall measurement surface, repeatedly hitting the corresponding measurement surface on the other side, obtaining the minimum value of the distance between the two measurement surfaces; moving the workshop girder trolley along the wall direction and measuring, obtaining a plurality of minimum value data; obtaining the parallelism data between the walls of the gantry
machine tool according to the plurality of minimum value data; and adjusting the corresponding distance between the walls of the gantry
machine tool according to the parallelism data until the parallelism requirement is reached.
