Abstract

A rigid-flexible coupling platform and a motion platform with an enhanced flexible hinge group, the rigid-flexible coupling platform with an enhanced flexible hinge group includes: a rigid frame of the motion platform, a core motion platform, and a flexible hinge group; the flexible hinge group includes: multiple There are two sets of gasket groups between two adjacent spring sheets; the rigid frame of the motion platform is connected to the core motion platform through the flexible hinge group. The stiffness of the flexible hinge group of the rigid-flexible coupling platform is increased, which greatly increases the ability of the guiding mechanism to bear large loads, and is suitable for the design of motion platforms with different structural sizes.

Description

technical field [0001] The invention relates to the technical field of high-precision motion, and more specifically relates to a rigid-flexible coupling platform and a motion platform with a reinforced flexible hinge set. Background technique [0002] Flexible hinges are widely used in the design of precision motion platforms due to their frictionless and lubrication-free properties. In precision motion platforms, flexible hinges are mainly designed as guiding mechanisms. In the precision motion platform, when the motion platform starts, stops and micro-displacement feeds, as a frictionless motion pair, the flexible hinge mainly realizes the motion through its own elastic deformation. The above-mentioned working principle of the flexible hinge makes the motion platform based on the typical flexible hinge guide mechanism mainly suitable for light load occasions, which limits its application in heavy load occasions. In addition, due to the repeated deformation of the flexibl...
