Excavator arm and loader rocker arm circular automatic welding machine

Abstract

The invention belongs to an automatic circumference welding machine for movable arms of excavators and swing arms of loaders. The automatic circumference welding machine comprises a lower bottom plate (21), an upper main plate (13) and a gear motor (7), and is characterized in that a mandrel (10) is movably arranged between the lower bottom plate (21) and the upper main plate (13); a first gear (2) and a positioning shaft seat (1) are arranged on the lower portion of the mandrel (10); four carbon brush copper rings (8) are arranged on the upper main plate (13), are positioned on the upper portion of the mandrel (10), are in contact with the mandrel (10) and are arranged on carbon brush holders (11), a conductive slip ring (12) is arranged on the mandrel (10) and is positioned above the carbon brush copper rings (8), and a pneumatic slip ring (14) is arranged above the conductive slip ring (12); a control panel (18) and the gear motor (7) are arranged on the left side of a space between the lower bottom plate (21) and the upper main plate (13). The automatic circumference welding machine has the advantages of simple structure, low cost, wide application range, good welding quality, uniform welding bead, smooth appearance and high welding efficiency.

Description

technical field [0001] The invention belongs to a welding machine, and particularly designs an automatic circular welding machine for excavator arm and loader rocker arm. Background technique [0002] Both the excavator arm and the loader rocker arm are of circular structure, which requires uniform welding, good quality, and good appearance. The original production is manual welding, the quality cannot be guaranteed, and the uniformity and appearance are not ideal. Low efficiency and high labor intensity. With the advancement of science and technology, there have been a variety of welding machines, which have complex structures and high costs, and are especially unsuitable for welding the circumference of parts of large-scale machinery such as excavator arms and loader rocker arms with a diameter of 200 to 2000 mm. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and provide a welding machin...
