Abstract

The invention discloses a triaxial movement platform, comprising a base, a Y axis movement system assembled at two ends of the base, an X axis movement system erected in the middle of the base and a Z axis movement system fixed on the X axis movement system, wherein, the X movement system, the Y movement system and the Z axis movement system respectively comprise a linear motor and a sliding device, which comprises a lead rail and a sliding block; the X axis movement system also comprises a cross beam, on which the linear motor used for driving the X axis movement system and the lead rail arefixed; the Z axis movement system also comprises a fixed bracket, on which the linear motor used for the Z axis movement system and the lead rail are installed. The triaxial movement platform not only can improve the system operation stability and accuracy but also can realize the high speed and accurate positioning of load.

Description

【Technical field】 [0001] The invention relates to a motion platform, in particular to a three-axis motion platform driven by a linear motor. 【technical background】 [0002] The traditional motion platform is usually realized by rotating the motor to drive the synchronous belt, screw or ball screw. However, due to inertia, stiffness, wear and other reasons, the response of the mechanical transmission is slow and lagging, and there is a certain tracking error, which also affects the operation of the system. Speed ​​and precision, meanwhile, mechanical configuration and motion range are also limited by the structure. [0003] Therefore, how to provide a three-axis motion platform that can overcome the above-mentioned problems caused by the rotating motor driving the synchronous belt, screw or ball screw has become an urgent problem to be solved. 【Content of invention】 [0004] The technical problem to be solved by the present invention is to provide a three-axis motion platf...
