Abstract

The invention provides a stator iron core lamination tool. The stator core lamination tool is used for laminating the stator core. The stator core lamination tool includes: a bearing part, the bearing part supports the stator core; an extruding part, the extruding part is arranged opposite to the bearing part , and the spacing is adjustable relative to the bearing part, the stator core is arranged between the bearing part and the extrusion part; and the mandrel part, the mandrel part is arranged between the bearing part and the extrusion part, and the outer diameter of the mandrel part The size is adjustable, and the stator iron core is sleeved on the core shaft. The lamination tooling of the stator iron core can ensure that the inner hole is not deformed, and the coaxiality of the stator iron core is guaranteed to be qualified.

Description

technical field [0001] The invention relates to the technical field of frequency conversion motors for compressors, in particular to a stator core lamination tool. Background technique [0002] With the rapid development of the motor industry, the miniaturization and thinning of brushless motors has become the trend of motor development. At present, the silicon steel sheets of the frequency conversion series stator cores for compressors have the characteristics of large slot holes, few buckle points, and thin walls. When the hydraulic press is used for lamination and the lamination tool is not matched, the silicon steel sheet is prone to skew, twist and deformation process problems, and its coaxiality cannot be guaranteed to meet the requirements. Contents of the invention [0003] The present invention aims to provide a stator core lamination tool to solve the technical problem in the prior art that the inner hole of the stator core is deformed during the lamination proc...
