Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a machine tool and process for flame quenching automatic heat treatment of shaft parts. Background technique [0002] The camshaft is a key component in the piston engine. The main body is a cylindrical rod with approximately the same length as the cylinder group. There are several cams on it, which are used to drive the valve and control the opening and closing of the valve. The camshaft rotates at a high speed in the engine and needs to bear a large torque, and also needs to bear periodic shock loads. The contact stress between the cam and the tappet is very large, and the relative sliding speed is also high, so the wear of the cam working surface is serious. In view of this situation, in addition to the high dimensional accuracy, small surface roughness and sufficient rigidity that the camshaft journal and the cam working surface should have, they should also have high...
