Welding method and structure for motor end ring and conducting bars

Abstract

The invention discloses a welding method and structure for a motor end ring and conducting bars. The welding structure comprises the end ring and the conducting bars. The welding structure is characterized in that grooves which are in one-to-one correspondence to the conducting bars are processed in the end surface of the end ring according to the dimensions of the end parts of the conducting bars, wherein the conducting bars and the grooves are correspondingly welded on the end ring. The welding structure reduces area of grooves in the end ring, and welding flux is limited in a single grooveduring welding, so that melting and curing of the welding flux in a welding process are guaranteed to be always limited in single groove, dosage of sliver brazing filler metal and soldering flux can be effectively reduced, welding cost is reduced, the conducting bars are guaranteed to be uniformly spaced and distributed in the peripheral direction of the end ring, the welding positions of the conducting bars are positioned simply and clearly, distance regulating does not need to be manually performed, welding operation difficulty is effectively reduced, and welding efficiency and welding quality for the end ring and the conducting bars is improved.

Description

technical field [0001] The invention relates to a welding method and structure of a motor end ring and a guide bar, which is used for welding the motor end ring and guide bars, and belongs to the technical field of motor manufacturing. Background technique [0002] The motor rotor is also the rotating part in the motor. The motor is composed of two parts: the rotor and the stator. It is used to realize the conversion device of electric energy and mechanical energy and mechanical energy and electric energy. The motor rotor is divided into the motor rotor and the generator rotor. The motor rotor mostly uses cage Type structure, so easy to rotate. [0003] The brazing of the end ring and the rotor guide bar in the manufacturing process of the cage-type motor rotor is an important link in the motor production process, and the quality of the brazing directly affects the performance parameters of the motor. In order to ensure the quality of the product, the end ring brazing struc...
