Description
technical field [0001] The invention relates to a crankshaft strengthened positioning method and a device thereof, in particular to a crankshaft fillet strengthened positioning method and a device thereof. Background technique [0002] The crankshaft is the core power output component in the internal combustion engine. For a large marine crankshaft, the output load is relatively large, and it is difficult to meet the strength requirements with a single strengthening method, so composite strengthening treatment is required. At present, the composite strengthening treatment mainly includes gas nitriding and fillet rolling composite strengthening or induction hardening and fillet rolling composite strengthening. Each kind of composite strengthening is inseparable from fillet rolling, and the fillet rolling of large crankshafts requires Applying a huge rolling force, the rolling machine tools developed at home and abroad cannot meet the rolling force requirements. [0003] In r...
