Abstract

The invention relates to a continuous annular automatic high-temperature fusion welding device for copper bar rotors of large and medium-sized motors. The device comprises a main underframe with a middle hole, a large rotary flat plate capable of intermittently rotating is mounted on the main underframe through a rotary support, and a round hole corresponding to the middle hole of the main underframe and a shaft head for positioning a workpiece are arranged in the middle of the large rotary flat plate. A plurality of height adjusting assemblies are arranged on the upper surface of the large rotary flat plate in the circumferential direction and used for abutting against an end ring of a workpiece to keep the end ring horizontal. The main underframe is further provided with a welding assembly with the radial position adjustable, the red copper bars to be welded in the end rings are sequentially in butt joint with the lower portion of the welding assembly along with rotation of the large rotation flat plate, and welding is completed through rotation intermittence. A rotary mechanical device drives the workpiece to rotate and cooperates with the welding assembly to complete welding, and the reliability is high. In the whole high-temperature fusion welding process, the speed is controllable, positioning is reliable, the process quality is improved, and meanwhile the operation labor intensity is greatly relieved.

Description

technical field [0001] The invention relates to the technical field of welding devices for copper bar rotors of electric motors, in particular to a continuous annular automatic high-temperature fusion welding device for copper bar rotors of large and medium-sized motors. Background technique [0002] In the prior art, for the welding process of copper bar rotors of various types of large and medium-sized motors, two methods are generally adopted: manual fusion welding or high-frequency induction welding. Although the production cost of the former method is low, it is easy to cause uneven heating, unstable welding quality and high labor intensity due to manual operation. Although the latter method has less labor intensity and stable quality, its electrical efficiency is low, the power of a single machine is small, the working voltage is too high, and the safety is poor, and related accessories such as special induction coils are expensive, and the input cost is high. Conten...
