Combined electric welding and power generating dual-purpose machine

Abstract

The invention provides a combined electric welding and power generating dual-purpose machine, which relates to an electric welding power generator. The combined electric welding and power generating dual-purpose machine comprises a rotor part, a stator part and a center connecting end cover, and is characterized in that a rotor is divided into a power generator part and an electric welding part, a rotor shaft of the power generating part is connected with a rotor shaft of the electric welding part in a conical coupling mode through a center passing screw bolt positioned in the center, a long shaft is formed, and meanwhile, the long shaft is fixedly arranged on a power output shaft of a gasoline engine or a diesel engine. The middle of the long shaft is provided with a bearing, and blades are arranged at the two sides of the long shaft. The power generator stator part is fixedly arranged between a front end cover and a middle connecting end cover provided with two air inlets, and the electric welding machine stator part is fixedly arranged between the middle connecting end cover and the back end cover provided with an air outlet through external full-length screw bolts. The combined electric welding and power generating dual-purpose machine has the advantages that a combined structure is adopted, the dismounting, the maintenance and the replacement are convenient, the use of the other one is not influenced on either the power generator or an electric welding machine is damaged, and the undamaged one can still normally work. The power generator gives out stable alternate current voltage in a magnetic assisting mode, and the electric welding machine generates constant current in an extinction mode. The power generation and the electric welding can realize the simultaneous work without mutual influence, and the electric welding and the power generation can both achieve the best effect. Double fans are respectively used for cooling, and the temperature rise is lower.

Description

technical field [0001] The invention relates to an electric welding generator, in particular to a dual-purpose electric welding generator. Background technique [0002] At present, gasoline generators, gasoline electric welding generators, and permanent magnet electric welding generators are widely used, but whether it is a DC excitation electric welding generator or a permanent magnet electric welding generator, the stator structure of the generator is basically the same. Two sets of windings are placed on one iron core, the generating winding and the electric welding winding. Electric welding and power generation are done by one rotor. When welding, a constant current power supply is required; when generating electricity, a constant voltage power supply is required. The effect of causing power generation and electric welding is all very poor, more can not use simultaneously for power generation and electric welding. Contents of the invention [0003] The purpose of th...
