Abstract

The invention relates to the technical field of motor welding, and aims to provide a rotor cage bar and end ring welding bench. According to the key points of the technical scheme, the rotor cage barand end ring welding bench comprises a support, a welding barrel and a workbench. A first welding hole, a second welding hole, a first limiting groove and a second limiting groove are formed in the workbench, and the first welding hole and the second welding hole communicate with the welding barrel. Limiting components are arranged on the side wall of the first limiting groove and the side wall ofthe second limiting groove, and each limiting component comprises a limiting hole, a spring and a limiting rod. The limiting holes are formed in the side wall of the first limiting groove and the side wall of the second limiting groove, one end of each spring is connected with the corresponding limiting hole, and the other of the spring is connected with the corresponding limiting rod. When the spring is under compression, the end, back from the spring, of the corresponding limiting rod is outside the corresponding limiting hole. The rotor cage bar and end ring welding bench can weld two groups of rotor cage bars and end rings at a time, and the welding efficiency is high.

Description

technical field [0001] The invention relates to the technical field of motor welding, in particular to a rotor cage bar and end ring welding processing table and a welding method. Background technique [0002] The motor rotor cage and the end ring are connected together by welding to form a current loop and ensure the safety and reliability of the structure. The rotor cage is evenly distributed on the circumference, and the end ring has an annular groove at the ring position corresponding to the diameter of the cage. , The cage bars are evenly distributed in the annular groove of the end ring, and the rotor cage bars and the end ring are welded together by a welding machine. During the welding process, the welding processing table is an indispensable device. [0003] At present, most of the welding processing stations on the market are such as figure 1 As shown, it includes a fixed frame, a placement cylinder with openings at both ends, and a working panel. One end of the p...
