Abstract
This utility model relates to the field of water pump rotor technology and discloses a quick-change locking structure for a water pump rotor in a dynamic balancing machine. The structure includes a quick-change assembly for quickly clamping the rotor. The quick-change assembly includes a detection shaft body, a fixed ring, and a movable ring. The fixed ring is fixedly connected to the detection shaft body, and a through hole is provided at the end of the detection shaft body. Symmetrical sliding holes are provided in the through hole. The movable ring is slidably connected to the sliding holes on the detection shaft body. The fixed ring and the movable ring are connected by mechanical components. Through the cooperation of the internal components of the quick-change assembly, simple pushing and pressing are used to lock and unlock the fixed ring and the movable ring. The rotor can be quickly locked and unlocked simultaneously. Compared to threaded locking, this improves the efficiency of rotor loading and unloading. The movable ring is pushed outward by a second spring, maintaining a relative tension between the second locking block and the first locking block, ensuring that the fixed ring and the movable ring do not wobble after locking.
