Abstract

The invention provides a magnetic levitation motion stage provided with controllable excitation linear synchronous motors and used for a vertical machining center. The magnetic levitation motion stage is characterized in that the magnetic levitation motion stage comprises a motion stage, a base, the controllable excitation linear synchronous motors, a levitation control system and a motion control system. The magnetic levitation motion stage has the advantages and effects that the electromagnetic thrust force is changed by adjusting the current of armature windings; the magnetic levitation forces are the unilateral magnetic pull generated between excitation magnetic poles on stators and rotor iron cores of the linear synchronous motors and are adjusted by adjusting the exciting current; the motion stage depends on the magnetic levitation forces generated by the two motors to operate and has the capacity of direct automatic levitation.

Description

technical field [0001] The invention relates to a motion platform, in particular to a magnetic levitation motion platform for a controllable excitation linear synchronous motor of a vertical machining center, belonging to the technical field of numerical control. Background technique [0002] Friction is an important factor affecting the machining accuracy of vertical machining centers, and it is also a factor that causes wear and noise. Therefore, reducing or eliminating friction has become a technical bottleneck that restricts the performance of linear motion platforms of vertical machining centers. The linear motion platform of the traditional vertical machining center is mostly driven by a servo motor, driven by a precision ball screw and supported by a sliding guide rail. During high-speed machining, there is serious mechanical friction, which is prone to elastic deformation and dust, which seriously affects the accuracy and quality of the machining center. machine life...
