Crankshaft milling machining center

The invention discloses a crankshaft milling machining center, and relates to a milling machining machine tool for machining parts such as crankshafts. The center involves a left main shaft, a vertical milling shaft, a right main shaft and a clamping device used for clamping a crankshaft; a workbench of the clamping device is provided with two centering clamping mechanisms arranged left and right, an angle positioning mechanism, an axial positioning mechanism and two supporting frames; the centering clamping mechanisms can slide upwards in the axial direction of the crankshaft; the angle positioning mechanism can slide in the radial direction of the crankshaft; and the axial positioning mechanism is arranged on the workbench in the area between the two centering clamping mechanisms. According to the center, the left and right machining center main shafts and left and right magazine tools are adopted, automatic tool changing machining is realized, a vertical milling head is matched, an angle positioning surface is milled, and the full-automatic machining of the two ends of the crankshaft is realized by one-time clamping, so that the machining precision is improved, the machining efficiency is improved, moreover, the unbalance amount after crankshaft machining can be greatly reduced, and the final machining quality of the crankshaft is improved.
