Automatic electric welding machine for closed type circular weld bead

Abstract

The invention discloses an automatic electric welding machine for a closed type circular weld bead. A second insulating plate of the automatic electric welding machine is fixedly arranged in a closed work chamber. A welding clamping device is fixedly arranged above the second insulation plate. A workpiece tool plate is arranged on the welding clamping device. A rotation drive motor arranged on the lower surface of the second insulating plate is connected with the welding clamping device through a motor connection sleeve. The lower portion of an upper top plate of the work chamber is fixedly connected with a cylinder through a U-shaped supporting frame. The bottom of a telescopic rod of the cylinder is fixedly connected with a welding gun supporting arm. A welding gun is installed at the other end of the welding gun supporting arm through a welding gun regulation device. A welding gun extension length adjustment switch, a welding gun height adjustment switch, a welding gun angle adjustment switch and a rotation drive motor rotating speed adjustment switch are arranged on the outer side of the work chamber. A wire feed device is connected with the welding gun, a carbon dioxide feed pipe is connected with the welding gun, and influences of electric welding smoke and splashing welding flux on the welding quality are reduced; the welding quality is improved, and the welding depth is uniform; and it is effectively avoided that workers get an electric shock in the use process.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of carbon dioxide shielded welding, and relates to a closed circular bead automatic electric welding machine, which has the effects of high welding efficiency and stable quality, and is especially used for batch welding in factories. [0003] Background technique: [0004] Welding in the machinery manufacturing industry usually adopts manual welding or robot welding. Manual welding is inefficient and labor-intensive; robot welding has high quality and fast welding, but the cost is too high. Moreover, manual welding and robot welding technology are not suitable for circular welding beads. Welding method. In the electric welding process, Tongsheng uses carbon dioxide as a shielding gas to protect arc welding, and sometimes uses CO 2 The mixed gas of +Ar is mainly used for manual welding. However, the welding quality of manual welding is unstable and requires high technical level of the operators, which is not...
