Description

Technical Field

[0001] The utility model belongs to the technical field of engine crankshaft processing bearing structure, and more specifically, particularly relates to a crankshaft processing fixture. Background Art

[0002] The crankshaft is the most important component in the engine. It bears the force transmitted from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. 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. After the crankshaft is initially processed and formed, it needs to be further processed by a fixture to fix the crankshaft support.

[0003] Based on the above, most crankshaft processing fixtures are currently only capable of fixed loading at a single angle, and the crankshaft needs to be inspected and processed on the surface after being fixed. The single-angle fixed loading is not convenient for adjusting the inspection surface of the crankshaft, so the crankshaft needs to be frequently disassembled and assembled when surface inspection and processing are required.
