Problems solved by technology

The working principle of the above-mentioned flexible hinges 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 flexible hinge for a long time during the movement, it is easy to cause cracks or even breakage of the guiding mechanism

Description

technical field [0001] The invention relates to the technical field of high-precision motion, and more specifically relates to a multi-axis rigid-flexible coupling motion platform. 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 flexible hinge for a long time during the moveme...
