The crankshaft is subjected to the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface needs to be wear-resistant, work evenly and have good balance. During the grinding process of the existing crankshaft, the clamping structure needs to be manually rotated to clamp and fix the crankshaft before grinding the crankshaft. However, due to the different shapes of the crankshafts, some positions are difficult to grind into place. Utility Model Content
