Large-cylinder-diameter marine diesel engine part cylinder sleeve inner hole measuring device

The invention relates to the technical field of cylinder sleeve inner hole measurement, in particular to a large-cylinder-diameter marine diesel engine part cylinder sleeve inner hole measuring device which comprises a cylinder sleeve, a machine tool, a measuring scale, a moving machine and a chip removal column, the cylinder sleeve is a cylindrical part and is arranged in a cylinder body hole of a machine body, and the machining link is the main step of cylinder sleeve machining. Common machining methods include turning, boring, taper machining and the like, and boring is a common inner hole machining method. The boring cutter generally adopts a mechanical boring cutter and a manual boring cutter. When the cylinder sleeve is machined, attention needs to be paid to workpiece fixation, cutter selection and machining speed, and the diameter of an inner hole of the cylinder sleeve is measured in the boring process so as to guarantee the size precision requirement; in addition, negative effects of narrow space ca
