Description

Technical Field

[0001] The invention relates to the technical field of piston welding machines, and in particular to an electron beam welding loading and unloading device and a control method thereof. Background Art

[0002] A welding machine refers to an electrical appliance that provides a power source with certain characteristics for welding. Welding is widely used in various industrial fields, such as aerospace, shipbuilding, automobiles, containers, etc., because of its flexibility, simplicity, convenience, firmness, reliability, and the fact that the welded material can even have the same strength as the parent material.

[0003] The electric welding machine is actually a transformer with a falling external characteristic, which converts 220V and 380V AC into low-voltage DC. Electric welding machines can generally be divided into two types according to the type of output power supply: one is AC power supply; the other is DC power supply. The DC electric welding machine can be said to be a high-power rectifier, which is divided into positive and negative poles. When the AC power is input, it is transformed by the transformer and then rectified by the rectifier, and then the power with a falling external characteristic is output. The output end will produce a huge voltage change when connected and disconnected. The two poles will ignite the arc when the short circuit occurs instantly, and the arc is used to melt the welding rod and welding material, and then cool them to achieve the purpose of combining them. The welding transformer has its own characteristics. The external characteristic is the characteristic that the voltage drops sharply after the welding rod is ignited.

[0004] During the piston welding process, the piston is usually fixed on a fixture and welded by a person holding a welding machine. Currently, manual welding of pistons has the disadvantages of poor quality stability, large coaxiality error and low efficiency. Summary of the invention
