The present invention relates to a backlash measurement device for a ram ball screw of a fueling machine to measure the backlash of an equipment driven in a state where a ram ball screw and a bearing ball of a fueling machine are combined. The backlash measurement device for a ram ball screw of a fueling machine comprises: left and right clamps for fixing a ball screw arranged in both sides to open and close upper and lower members on hinge parts like a hinge type and installed to fix a ball screw in both sides of a ball nut; sliding fixing shafts horizontally fixed in parallel while the upper and lower members of the left and right clamps are separated from each other at a predetermined distance; left and right fixing plates installed in the sliding fixing shafts fixed between the upper members of the left and right clamps to be slid and positioned in left and right sides of the ball nut to fix the ball nut in the left and right sides; left and right adjustment bolts horizontally fixed on positions where the sliding fixing shafts are fixed by the upper members of the left and right clamps to compress the left and right fixing plates; upper and lower support members installed to support and fix the upper and lower parts of the ball nut in a state of being fixed on the sliding fixing shafts; a dial gauge; and a bracket to fix the dial gauge on the upper support member. |
