Dynamic balance correction device

The invention discloses a dynamic balance correction device which comprises a workbench, a chuck, two drilling execution assemblies and a rotary driving assembly, the workbench is provided with a dynamic balance detection unit used for detecting dynamic balance information of a positioning workpiece on the chuck, and the number of the drilling execution assemblies is two. Wherein one drilling execution assembly is used for positioning a workpiece on a chuck to drill a lug hole, and the other drilling execution assembly is used for positioning the workpiece on the chuck to drill a balance hole. On one hand, repeated tooling during execution of multiple machining technologies can be avoided, the overall machining efficiency of the workpiece is improved, on the other hand, through one-time positioning, the reference consistency in the earhole drilling and dynamic balance correction process can be guaranteed, the dynamic balance detection result is more accurate, and therefore the dynamic balance correction quali
