The invention relates to the technical field of crankshaft heat treatment, in particular to internal combustion engine crankshaft heat treatment equipment which comprises a furnace body, supporting plates are fixedly connected to the two sides of the furnace body, first belt wheels and second belt wheels are rotationally installed on the supporting plates, the number of the first belt wheels is two, and a first synchronous belt is matched with the two first belt wheels; each connecting rod of a semi-finished crankshaft in a rotating state is clamped through the heating plate on the mounting plate, so that each connecting rod is supported and protected, the semi-finished crankshaft is prevented from being bent and deformed due to the action of gravity and centrifugal force in the furnace body rotating process, each connecting rod can bear larger centrifugal force, and the service life of the semi-finished crankshaft is prolonged. The rotating speed of the semi-finished crankshaft in the furnace body is increas
