ROTARY MICRO-ADJUSTMENT MECHANISM FOR A SYNCHRONOUS DOUBLE-DRIVE POSITIONING PLATFORM

摘要

A rotary micro-adjustment mechanism for a synchronous double-drive positioning platform (such as a gantry) is disposed between a beam and support pillars of the synchronous double-drive positioning platform and comprises a positioning pillar and elastic members. The positioning pillar is provided to pivot the beam relative to the respective support pillars to compensate displacement error of the beam and the support pillars. The elastic members are provided to resist the pivotal rotation between the beam and the support pillar by their restoring force, so as to improve the rigidity of the overall mechanism.
