The utility model relates to a crankshaft end face hole measuring and checking tool. The crankshaft end face hole checking tool comprises a big end measuring mechanism, a small end retaining mechanism and a bearing mechanism, wherein a checking tool body is flange-shaped, the inner hole of the checking tool body and the outer ring of a linear bearing are installed in an interference fit, the inner ring of the linear bearing is sleeved with the outer circle of the middle portion of a big end center, and the rear cone of the big end center is inserted into a taper hole disposed in a big end tailstock; and the rear cone of a small end center is inserted into a taper hole disposed in the front of a sleeve, a circular hole in the rear portion of the sleeve is connected with the front portion of a piston in a cylinder and fixed by a cylindrical pin, and the outer circle of the sleeve is inserted into an inner hole disposed in a small end tailstock and fixed by a screw F which is screwed into an end screw hole in the small end tailstock through a cylinder flange counter bore. The crankshaft end face hole checking tool is characterized in that when a crankshaft is pressed by the small end center driven by a piston rod of the cylinder in the axial direction, if a pin hole plug gauge and a screw hole plug gauge can be respectively aligned with a positioning pin hole and a screw hole of the crankshaft by manual operation on the checking tool body, the crankshaft end face holes are qualified, and otherwise, the crankshaft end face holes are unqualified. The crankshaft end face hole checking tool is high in detection efficiency, and reliable and accurate in measurement.
