Abstract

The invention relates to a field pipeline groove cutting machine which comprises a chuck, a driving chuck, a speed changer, a motor, a belt pulley and a milling cutter device, wherein the chuck and the driving chuck are respectively formed by an outer ring, an inner ring and a bracket; the outer ring and the inner ring are arranged in a coaxial way, a bearing is arranged between the outer ring and the inner ring, and the inner ring is provided with a set screw; the inner ring of the driving chuck is provided with a screw hole, and the inner ring is fixedly connected with the belt pulley by a bolt; the motor is connected with the speed changer by a gear; the speed changer is connected with the belt pulley by a transmitting belt; the milling cutter device comprises a groove milling cutter, a milling cutter box and a milling cutter moving mechanism; the milling cutter moving mechanism is arranged in the milling cutter box; the groove milling cutter is arranged on the milling cutter moving mechanism. According to the field pipeline groove cutting machine, the processed pipeline is fixed on the groove cutting machine by the chuck and the driving chuck and is driven to rotate by the motor through the speed changer, and groove cutting is carried out on the pipeline by the groove milling cutter, so that the pipeline groove cutting quality and the pipeline welding quality are improved, and pipeline laying construction efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of pipeline equipment installation and welding, and relates to an on-site pipeline bevel cutting machine. Background technique [0002] Petroleum and chemical companies design and install a large number of process pipelines to meet the needs of production and operation. The laying of pipelines is to weld the pipes together to form pipelines. At the construction site of laying pipelines, it is necessary to cut grooves at the joints of pipelines to facilitate butt welding of pipelines. The traditional method is to cut grooves by gas cutting. When laying a long-distance oil pipeline, the number of pipeline grooves that need to be processed is huge. Using the conventional gas cutting method to process the grooves is not only slow, but also difficult to control the quality of the grooves. Poor quality of the grooves will increase the difficulty of subsequent welding, resulting in Slow welding speed, poor quality...
