Multi-purpose assembly fixture for skewed laminated rotor core assembly

Abstract

The invention discloses a multipurpose assembly fixture for a skewed and laminated rotor core assembly, belongs to a motor manufacturing tool, and aims at providing the rotor core assembly assembling fixture which is high in assembling precision, simple in structure and beneficial to mold removal. The multipurpose assembly fixture comprises a base, a pressing block, a mandrel and plug pins. A cushion plate (7) and three positioning columns (2) evenly distributed with the center of the cushion plate as the circle center are fixed to the base (6). A pressing plate (1) is positioned on the positioning columns (2). Three first horn holes (9) with the center of the cushion plate as the circle center are formed in the pressing plate (1). Three second horn holes (5) with the center of the cushion plate as the circle center are formed in the cushion plate (7). Each first horn hole (9) and the corresponding second horn hole (5) are staggered by an angle. The plug pins are inserted between the first horn holes (9) and the second horn holes (5). The mandrel (4) penetrates the base (6), the cushion plate (7) and the pressing plate (1) to extend upwards. The multipurpose assembly fixture is multipurpose and is the rotor core assembly assembling fixture.

Description

technical field [0001] The invention relates to a clamp for assembling a laminated rotor core assembly, in particular to a clamp for assembling a skewed laminated rotor core assembly; it belongs to the tooling for motor manufacturing. Background technique [0002] As we all know, the iron core assembly is a component that constitutes the rotor of a DC motor, and is usually formed by laminating iron sheets with a number of punching grooves distributed along the edges; currently, lamination molds are usually used to assemble the iron core assembly. The existing chute armature iron core stacking die generally consists of stacking mandrels, upper and lower backing plates, locking nuts, positioning keys, pressure heads and the like. The announcement number is "CN203014613U", the name is "Invisible Pole Inclined Slot Rotor Core Stacking Die", and "CN202190188U", the name is "Spherical Key Slope Rotor Core Stacking Die" respectively discloses two stacked inclined The assembly devi...
