Problems solved by technology

The stator is composed of three parts: stator core, stator winding and machine base. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic field lines in the rotating magnetic field to generate (output) current. The stator core is an important component of the motor stator One, at present, when the motor stator is welded, the filler metal is often used for welding, the welding deformation is large, and the welding quality is poor. At the same time, multi-point synchronous automatic welding cannot be realized during welding, which affects work efficiency.

Abstract

The invention discloses a small motor stator core welding structure, which comprises a stator core unit, wherein the stator core unit is sleeved on the sleeve pipe, and the stator core unit is formed by stacking and combining a plurality of core punching sheets; and each iron core punching sheet is composed of an iron core yoke portion of an annular structure and a plurality of iron core tooth portions integrally formed on the inner side of the iron core yoke portion at equal angles, and stop blocks are arranged at the ends of the iron core tooth portions. According to the small motor stator core welding structure, welding grooves and welding bumps are symmetrically arranged at the bottom and top parts of cross sections of the iron core punching sheets, so that the welding bumps can be matched with the welding grooves for alignment stacking during stacking welding, and meanwhile, the welding bumps can be directly subjected to welding hot melting, so that metal filling is not needed during welding, the welding operation is more convenient, the welding quality is improved, the metal medium consumption is guaranteed to be balanced during welding, and the welding quality and the welding flatness are improved.

Description

technical field [0001] The invention relates to the technical field of stator core welding, in particular to a small motor stator core welding structure. Background technique [0002] The motor stator is the stationary part of the motor. The stator is composed of three parts: stator core, stator winding and machine base. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic field lines in the rotating magnetic field to generate (output) current. The stator core is an important component of the motor stator One, at present, when the motor stator is welded, the filler metal is often used for welding, the welding deformation is large, and the welding quality is poor. At the same time, multi-point synchronous automatic welding cannot be realized during welding, which affects work efficiency. Contents of the invention [0003] The object of the present invention is to provide a welding struct...
