The utility model provides a finish machining tool for a combination surface of a crankcase body and an oil pan on a V-shaped engine, which comprises a V-shaped supporting block, a plurality of workpiece supporting pieces arranged on the left side wall and the right side wall of the V-shaped supporting block, and pressing mechanisms arranged at the front ends and the rear ends of the left side wall and the right side wall of the V-shaped supporting block respectively. The pressing mechanisms vertically face the side wall direction of the V-shaped supporting block and tightly press the hole walls of the corresponding air channel holes, and the pressing force direction and the supporting force of the position, close to the pressing mechanisms, of the crankshaft box body are located on the same straight line. In the design, when the crankcase is clamped and fixed, the directions of supporting force and pressing force of the crankcase are on the same straight line, so that the overall rigidity of the crankcase se
