Abstract

The utility model discloses a positioning and pressure maintaining device for a Halbach magnetic assembly. The positioning and pressure maintaining device comprises a machine body, a jig for placing the Halbach magnetic assembly, a positioning assembly and a pressure maintaining assembly, the machine body is provided with a bottom plate, a middle plate and a top plate, and the middle plate is fixedly arranged between the bottom plate and the top plate; the jig is placed on the middle plate, the positioning assemblies are arranged on the portions, on the two sides of the jig, of the middle plate, and the positioning assemblies move relative to the jig so as to position the jig. The pressure maintaining assemblies are arranged on the upper surface of the bottom plate and the lower surface of the top plate respectively, the jig and the middle plate are provided with long-strip-shaped through holes, the pressure maintaining assemblies on the upper surface of the bottom plate stretch into the long-strip-shaped through holes in an upward jacking mode and are matched with the pressure maintaining assemblies on the lower surface of the top plate to conduct downward pressing movement, and therefore pressure maintaining is conducted on the Halbach magnetic assembly on the jig. The positioning assembly is used for positioning the two sides of the jig for placing the Halbach magnetic assembly, and the pressure maintaining assembly is used for maintaining pressure on the upper surface and the lower surface of the Halbach magnetic assembly on the jig, so that a magnet and an iron piece of the Halbach magnetic assembly can be perfectly attached, the qualified rate and the production efficiency of products are improved, and the production cost is reduced. And the automation degree is high, and the manual operation amount is reduced.
