The invention discloses a precision piezoelectric driving lifting platform adopting a four-link hinge stator, and aims to solve the technical problems of weak load ability, low positioning precision and the like of a current piezoelectric driving lifting platform. The lifting platform is composed of an upper sealing shell, a lifting platform, a transmission assembly, a base, a four-link hinge stator assembly and a packaging bolt, wherein the lifting platform is in threaded connection with the transmission assembly, the transmission assembly is in transition fit with the base, the transmissionassembly is in contact with the four-link hinge stator assembly fixedly installed in the base, the packaging bolt is in threaded connection with the base, and therefore the upper sealing shell and thetransmission assembly are fixedly installed on the base. According to the lifting platform, the four-link hinge stator is used for surface contact driving, through kinetic characteristics of a four-link, the radial driving force of the four-link hinge stator is increases, meanwhile, a threaded connection transmission mode is adopted to realize output mode conversion, and the vertical output stepdistance of the lifting platform can be reduced; and the lifting platform has the characteristics of strong load capacity, high positioning precision, good motion stability and the like, and has a wide application prospect in the field of precision driving and positioning.
