Abstract
The invention relates to a crankshaft support centre frame comprising a beam, a bracket, an air cylinder and a V-shaped support block. Two ends of the beam are supported and fixed on a machine tool body; the beam is provided with a support base; the bracket is fixedly installed on the support base through screws; the air cylinder is fixedly installed on the bracket; and the V-shaped support block is fixedly connected with a piston rod of the air cylinder. The air cylinder is controlled by a machine tool program to act; and when the crankshaft support centre frame is used, the V-shaped support block is abutted against a crankshaft journal to be machined by a turning tool. The crankshaft support centre frame disclosed by the invention has a rational structure and is simple to manufacture and convenient to use. Under the action of the air cylinder, the V-shaped support block can counteract deformation caused by shortage of rigidness of an irregular shaft resulting from back-knife force of a cutting tool, and meanwhile, can avoid vibration resulting from own imbalances of irregular shafts and higher rotating speed. The machining efficiency is improved greatly while the surface machining quality is improved.
