Precise instrument vibration isolation platform

Abstract

The invention discloses a precise instrument vibration isolation platform. The precise instrument vibration isolation platform comprises a load platform module, a vibration isolation system module anda mobile support module. Three modules of the vibration isolation device are distributed from top to bottom, and a vibration isolation system module (composed of three vibration isolator assemblies)is located in the middle and connected with the load platform module and the mobile support module up and down. The designed vibration isolation system module is of a closed multi-group parallel structure, and has the characteristics of high bearing capacity, good stability and the like; meanwhile, a three-point six-spring oblique convergence type supporting design is adopted for the vibration isolator assemblies, the three-direction equal-rigidity and equal-fundamental-frequency functions under a space coordinate system are achieved, and good vibration reduction and isolation performance is achieved; besides, vibration isolation devices are provided with limiting locking assemblies in parallel, the limiting protection effect on a precise measuring instrument can be achieved, and good safety is achieved. The vibration isolation device integrally adopts a travelling crane integrated design, is movable, lockable, convenient to use and fast, and has very strong environmental adaptability.The whole structure is simple, the manufacturing cost is low and the application prospect is wide.
