Embodiment Construction

[0013] Invented simple precision translation stage such as figure 1 As shown, including base 1, vibration isolator 2, fixed hexagon socket screw 3, linear guide rail 4, hexagon socket set screw 5, micro-motion table 6, piezoelectric ceramic driver 7, linear grating scale 8, linear motor 9 .

[0014] The base 1 is used as the carrier of the entire stage, and plays a role of installation support for the entire component. The vibration isolator 2 installed at the bottom of the base 1 plays a role of vibration isolation and can effectively eliminate the impact of external factors, especially external vibration, on the performance of the entire platform.

[0015] The linear guide rail 4 is fastened on the base 1 by fixing the hexagon socket head cap screw 3, and acts as a guiding part for large stroke movement. A linear motor 9 is installed on the linear guide rail 4, and is connected with the micro-motion platform 6 through the hexagon socket set screw 5. The hexagon socket hea...

Abstract

The invention relates to a simple precision displacement platform, which comprises a base, a vibration isolator, an internal hexagonal fastening screw, a linear guide rail, an internal hexagonal set screw, a micro-displacement work table, a piezoelectric actuator, a linear grating bar and a linear motor, wherein the displacement platform is a precision one-dimensional displacement platform. As the displacement platform is provided with the linear motor and the piezoelectric actuator, compared with a traditional ball screw mode, the displacement platform has the advantages that intermediate mechanical transmission links are greatly decreased, and the length of a transmission chain is reduced to be zero. The displacement platform is capable of realizing large-displacement rapid positioning and small-displacement precision effective output. Besides, the displacement platform has the advantages of simple structure, high response speed, high precision, high dynamic stiffness, short acceleration and deceleration process, quietness in movement, low noise, high efficiency and the like, and can be used for the field of precision measurement and precision machining.
