Abstract

This invention belongs to the field of automotive manufacturing technology, specifically relating to an assembly machine for a permanent magnet stator of an automotive starter motor. The upper assembly fixture has a pushing assembly, which includes pushing members. Multiple pushing members simultaneously approach or move away from each other via a second drive mechanism. The lower assembly fixture has a support clamping assembly arranged opposite to the pushing assembly. The support clamping assembly includes support clamping members, the support clamping portions of which extend upwards from the assembly operation window. A pushing channel exists between the support clamping portions of two adjacent support clamping members, allowing the pushing portions of the pushing members to vertically extend or reciprocate linearly along a direction from near to far from the machining positioning center L. Multiple support clamping members simultaneously approach or move away from each other via a third drive mechanism. The equipment has high reliability, saves labor, and improves the assembly efficiency of automotive starter motor permanent magnet stators.
