Abstract

The invention discloses a rigid-flexible coupling sliding block. The sliding block comprises a sliding component, a rigid frame installed on the sliding component, a guide block connected with the rigid frame through a flexible hinge set and a tension force adjustment mechanism enabling the rigid frame to generate deformation. A low-rigidity mode can be adopted in a tiny displacement mode and at the movement tail end, and precise compensation of tiny displacement and errors is realized through elastic deformation; and in a high-speed movement stage, a high-rigidity mode is adopted, the vibration of the component in the movement process is reduced, and the control bandwidth is broadened.

Description

technical field [0001] The invention relates to the technical field of high-speed precision motion control, and more specifically, to a rigid-flexible coupling slider. Background technique [0002] In the field of high-speed precision motion control, the motion mechanism based on the mechanical contact motion pair is affected by the friction of the guide rail and the elastic vibration of the working platform, and the accuracy can only reach the micron level. In the case of higher precision requirements, the industry needs to use air floatation, magnetic levitation and static pressure guide rails to reduce or even eliminate the influence of friction. The cost is high and the requirements for the use environment are high, so it is not suitable for electronic manufacturing occasions with large quantities and a wide range. However, Moore's Law in the electronics manufacturing industry (when the price remains constant, the number of components that can be accommodated on an integ...
