A step stroke adjustment mechanism and servomotor

Abstract

The utility model relates to water conservancy power generation technical field especially relates to a kind of hierarchical stroke adjusting mechanism and servomotor, mechanism includes: movable cavity, connecting rod, piston, first adjusting ring and second adjusting ring;Connecting rod one end extends into movable cavity, and end portion is detachably connected with piston built-in in movable cavity;First adjusting ring and second adjusting ring are respectively arranged at the two ends of piston, first adjusting ring is sleeved in the end portion of connecting rod, and the end face towards piston is attached with the opposite surface of piston, and the end face of second adjusting ring is attached with the other end surface of piston, and is detachably connected with piston;By the dismounting of first adjusting ring and second adjusting ring, a servomotor can realize the change of multiple strokes, to adapt to different water level change requirement, improve the adaptation of working condition, assembly connection is stable, ensure normal working accuracy;And detachable connecting structure is used between each component, and dismounting process is simple, reduce maintenance difficulty and time cost, avoid resource waste.
