Large range moving magnetic suspension planar working table

Abstract

The invention relates to a large-range mobile maglev plane workbench, relating to a maglev plane workbench, in particular to a large-scale mobile maglev plane workbench, which is mainly used in the fields of manufacturing equipment and robots. The workbench includes a base and a mobile platform. The mobile platform is composed of a platform and a mobile electromagnetic structure arranged at the bottom of the platform. A planar permanent magnet array is arranged on the top of the base. The mobile electromagnetic structure is composed of more than three armature units. Each armature unit includes an armature core, an X-phase winding and a Y-phase winding. The X-phase winding and the Y-phase winding overlap each other in the vertical direction on the bottom surface of the armature unit, and any effective side of the X-phase winding is connected to the Y-phase winding. Any effective side of the winding is perpendicular to each other. Since the moving range of the mobile station is not limited by the size of the mobile station, the mobile station can move on a base station whose planar size is much larger than that of the mobile station, thereby greatly increasing the relative stroke of the mobile station and realizing the large size of the mobile station Range panning.

Description

technical field [0001] The invention relates to a maglev planar workbench, in particular to a large-range mobile maglev planar workbench, which is mainly used in the fields of manufacturing equipment and robots. Background technique [0002] The XY table is an electromechanical component used to realize the plane relative movement between the workpiece and the tool, between the base part and the end part, and between multiple workpieces in manufacturing equipment and robots. The traditional XY table is composed of two sets of linear drive units stacked vertically. Each set of linear drive units consists of a rotary motor, a set of linear motion conversion mechanism and a set of linear guide rails, or a linear motor and a set of linear guides. rail composition. The linear drive unit located on the bottom not only bears the drive of the end bearing table, but also bears the mass of the top linear drive unit, thus causing a serious imbalance in the motion inertia of the XY tab...

Problems solved by technology

figure 1 (b) and figure 1 (c) shows the situation when the mobile station moves to the uppermost and lowermost sides in the Y direction. At this time, the permanent magnetic array M x1 and M x2 The lower boundary and the upper boundary of the axis respectively coincide with the center line 2-2', so the movement stroke of the mobile station in the Y direction is less than or equal to the distance d≈50mm between the boundaries of the permanent magnetic array, and the stroke in the X direction is also subject to the above principle limit, the range of movement is less than 20% of the side length of the mobile station
