Assembly device and assembly method for rotor core

Abstract

The invention discloses an assembly device and an assembly method for a rotor core and aims at solving the defect that a disqualified product appears easily due to low assembly automation degree of the rotor core, low positional accuracy of the rotor core and low assembly efficiency. The assembly device comprises a mounting base, a support plate, a support and a compression shaping mechanism, wherein a feed channel and an ejector piston cylinder are arranged on the support plate; a lifting rotary disc is arranged on the support plate; a fixed shaped head and a movable shaped head are arranged on the support plate; the movable shaped head is connected to a feed piston cylinder expansion link; the front end of an ejector piston cylinder expansion link is connected to an ejecting rack; an elastic ejector rod is movably arranged on the rotary disc; a mandrel capable of lifting vertically arranged on the lower end of the compression shaping mechanism; a shaping material return sleeve coats the mandrel; a compression spring coats the mandrel; a plurality of elastic locating core and a plurality of shaping groove shape knives are movably arranged on the shaping material return sleeve; a location sensor is arranged on a position close to the upper ends of the elastic locating cores; and a grab mechanism is arranged at the side of the compression shaping mechanism.

Description

technical field [0001] The invention relates to a rotor core assembly device, more specifically, it relates to a high-efficiency rotor core assembly device and an assembly method. Background technique [0002] The rotor iron core is an important part of the motor. In the process of rotor assembly, it is necessary to assemble the auxiliary balance weight, iron core, magnetic steel, retainer, and main balance weight in sequence. Finally, riveting and blanking are carried out. The iron core is equipped with a magnetic steel installation. Slots and riveting holes for the assembly of magnetic steel and riveting of rivets, so it is necessary to ensure accurate assembly positions during the assembly of the iron core. However, in the prior art, the assembly automation of the rotor core is low, the positioning accuracy of the assembly position is low, the assembly efficiency is low, and unqualified products are prone to appear. [0003] Chinese patent announcement number CN203679703...
