Patent attributes
A first grinding head is provided on a base frame via a first movable body and a first grinding base. The proximal portion of the tilt arm is tiltably fitted in the housing of the grinding head. A measuring device is rotatably coupled to a distal portion of the tilt arm. A gauge and a measuring pin are coupled to the lower end of the measuring device, and the gauge is engaged with a crankpin of a crankshaft. A tilt center of the tilt arm is arranged on the same axis as the rotation center of the first grindstone ISA. When the tilt arm is tilted, the position of the measuring device is changed, accordingly. However, since the relational relationship between the first grindstone ISA and the gauge is not changed, the position of the gauge is easily adjusted in accordance with the diameter of the crankpin. Accordingly, a grinding machine is provided that simplifies the movement path of the gauge of the measuring device, thereby allowing the outer diameter of the workpiece to be quickly measured.
