A kind of automatic welding device and its welding process

Abstract

The invention discloses an automatic welding device and a welding process thereof. The welding device comprises a vertical column, a transverse arm and a welding gun, wherein one end of the transverse arm is arranged on the vertical column, the other end of the transverse arm is provided with a main shaft and a main shaft motor, the main shaft motor is used for driving the main shaft to rotate, the main shaft is provided with a welding wire delivery machine, the welding wire delivery machine is used for delivering welding wires to the welding gun, the main shaft is provided with an X-axis slide rail, a Z-axis slide rail is arranged on the X-axis slide rail, a rotary body is arranged on the Z-axis slide rail, and the welding gun is arranged on the rotary body. The welding process comprises the following steps of utilizing a tooling clamp on a base to position a welding workpiece; enabling a manual pull rod on an elastic center rod to lift the elastic center rod, putting another welding workpiece under a press head, and pressing and positioning the two welding workpieces together; adjusting the position of the welding gun, and driving the main shaft and the slide rails to weld a welding seam; after welding, lifting the elastic center rod, ascending the press head, and taking off the welding workpieces. The automatic welding device and the welding process have the advantages that the pre-fixing for manual point welding is not needed, and the welding production efficiency is improved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an automatic welding device and a welding process thereof. Background technique [0002] At present, compared with other types of metal forming processing, welding processing is not highly automated and relies more on manual operations. There are deficiencies in welding quality, work efficiency, personnel safety, energy saving and environmental protection. Although the welding robot industry has developed in recent years Rapid, powerful welding robot, but its price is expensive, unaffordable by ordinary small and medium-sized enterprises, and there is no common and open technology among robot manufacturers, so different brands of robots operate differently, and usually require professionals trained by manufacturers It can only be operated, which makes it difficult for robots to enter small and medium-sized enterprises with weaker technical strength for a while.

[0002] At present, compared with other types of metal forming processing, welding processing is not highly automated and relies more on manual operations. There are deficiencies in welding quality, work efficiency, personnel safety, energy saving and environmental protection. Although the welding robot industry has developed in recent years Rapid, powerful welding robot, but its price is expensive, unaffordable by ordinary small and medium-sized enterprises, and there is no common and open technology among robot manufacturers, so different brands of robots operate differently, and usually require professionals trained by manufacturers It can only be operated, which makes it difficult for robots to enter small and medium-sized enterprises with weak technical strength for a while.

[0003] In order to realize welding automation, the industry uses more welding machines, that is, special welding equipment specially designed for a certain field or a certain product. This type of equipment has poor versatility and a single welding variety has a small application range.
