Crankshaft machining machine; and method for drilling weight relief holes in a crankshaft

摘要

Crankshaft machining machine. The crankshaft machining machine comprises a support (2) for supporting at least one crankshaft (100) and at least one actuator (1) for driving a machining tool for machining the crankshaft. The bracket (2) is configured to secure the crankshaft with at least two clamping devices (21) configured to secure the crankshaft in correspondence with at least two main crankshaft sleeves (103). The bracket (2) rotates relative to a vertical axis (a) to modify the angle of attack between a longitudinal axis (b) of the crankshaft (100) and the actuator. The support is equipped with a rotating mechanism (22) which moves between a retracted position in which it does not interact with the crankshaft (100) and a drive position in which the rotating mechanism (22) interacts with the crankshaft. (100) in order to rotate the crankshaft (100) with respect to its longitudinal axis (b). The machine is suitable for drilling weight relief holes in crankshafts.
