Abstract

The invention relates to a three-degree-of-freedom parallel mechanism based on polyvinyl chloride gel (PVC gel) driving, and belongs to the technical field of intelligent material application. The three-degree-of-freedom parallel mechanism is composed of a fixed platform, a PVC gel driver, a transmission rod, a connecting rod and a movable platform. The PVC gel driver is installed on the fixed platform, output force and output displacement of PVC gel are transmitted through a transmission rod, the transmission rod is connected with a connecting rod through a spherical pair, and the connecting rod is connected with the movable platform through a rotating pair; in a power-on state, the PVC gel driver can drive the transmission rod to generate linear motion, so that the spatial three-degree-of-freedom motion of the movable platform can be realized; the three-degree-of-freedom parallel mechanism is light in weight, free of noise, low in power consumption and environmentally friendly, and has high application value in the precise positioning fields of aircraft assembly, intelligent robots, integrated circuits, biological science and the like.

Description

technical field [0001] The invention relates to a three-degree-of-freedom parallel mechanism driven by PVC gel, which belongs to the technical field of intelligent material application. Background technique [0002] Parallel mechanism is widely used in precision positioning technology because of its stable structure, large bearing capacity, small motion load and high motion accuracy. Precision positioning technology has important research value in the fields of aircraft assembly, integrated circuits, and biological sciences. Among them, the multi-degree-of-freedom positioning platform is the core technology to achieve high-precision positioning. At present, parallel mechanisms are all driven by motors. Motor drives require complex gear transmission mechanisms with many transmission links, which will cause problems such as vibration, impact, noise, and error accumulation. Therefore, the application of this mechanism in precision positioning fields such as aircraft assembly, ...
