Description

Technical Field

[0001] The utility model relates to the technical field of crankshaft production, in particular to a dynamic balance detection device. Background Art

[0002] The crankshaft is a crucial component within an automotive engine, delivering power and driving accessories. After machining, the crankshaft undergoes numerous tests, including dynamic balancing, which primarily involves using a crankshaft balance performance tester to assess the balance of the crankshaft during rotation. The crankshaft assembly, a core component of the engine, consists of the crankshaft, connecting rod, and piston pin. The crankshaft assembly converts the reciprocating motion of the pistons into rotational motion while also providing power to the engine. However, this power generation generates centrifugal forces, necessitating the balance of the counterweight assembly. However, testing the crankshaft assembly for quality often relies on manual labor and empirical judgment, resulting in low efficiency, limited accuracy, and susceptibility to human error, making it difficult to meet the high quality control standards required by modern industrial production.
