Description
Technical Field
The invention relates to the technical field of surface thermal spraying engineering, in particular to an electric arc spray gun rotating device.
Background
The thermal spraying technology can solve the problems of wear resistance, corrosion resistance, insulation, electric conduction, friction reduction and the like, and change the surface performance of parts. The double-wire electric arc is an important process method in the thermal spraying technology, and the electric arc spraying technology takes the electric arc as a heat source, atomizes molten metal wires by high-speed airflow and sprays the atomized metal wires onto the surface of a workpiece at high speed to form a coating.
The spraying of the cylinder hole and the cylinder sleeve of the automobile engine can reduce oil consumption and carbon dioxide emission. The whole automobile quality is reduced, the oil consumption can be reduced, the whole automobile quality can be reduced by adopting the aluminum alloy cylinder body, but the inner wall of the aluminum alloy cylinder hole is easy to wear, so that the service life is prolonged by spraying a layer of better wear-resistant material on the surface of the aluminum alloy cylinder hole. The electric arc spraying technology reduces the quality of an engine and improves the wear resistance, and on the other hand, the naturally formed porosity of 3% -5% by electric arc spraying can store oil, so that the lubricating performance of a cylinder hole in the using process is obviously improved.
At present, the mode of boring a large cylinder hole and embedding a cylinder sleeve is generally adopted for repairing the cylinder hole of the engine manufactured in China. The electric arc spraying technology is applied to repairing the cylinder hole of the engine, the original size of the cylinder hole can be recovered under the condition of not changing the structure, scrapping is reduced, cost and raw materials are saved, but the difficulty of double-wire electric arc inner hole spraying is mainly two points: 1. an excessively small inner hole cannot ensure enough spraying distance, so that a workpiece matrix is overheated, the coating quality is affected, and the coating is cracked and falls off; 2. the traditional electric arc spraying gun can not realize the rotating function when the double-wire is fed.
While patents CN107930885A and CN107321518A both refer to a device for rotating a female twin-wire arc torch, both of them can solve the above problems, but both of them perform 360 ° rotation spraying by means of the simultaneous rotation of the torch and the wire feeder. Moreover, when other devices with narrow inner container space are sprayed, the scheme cannot meet the requirement of spraying compactness.
