Pipe cutting positioner

Abstract

The invention provides a cutting positioning machine which includes a frame body, a rotary positioning mechanism rotatablely arranged on the frame body, and a transmission mechanism driving the rotary positioning mechanism to rotatablely position; the rotary positioning mechanism includes a rotary disc with a chamber, a chain fixedly circled on the external circumference of the rotary disc, and a clamp positioning mechanism arranged at the chamber close to the rotary disc for clamping the pipes; the transmission mechanism includes at least one transmission chain wheel engaged with the chain; as the diameter of the rotary disc of the rotary positioning mechanism on the positioning machine is not restricted by the process, the large rotary disc can be added and meanwhile be matched with the clamp positioning mechanism, tightly clamping the pipes to be cut with different types, in particular to the large types; furthermore, the chain wheel is adopted for transmission, which ensures the stability of the rotation of the rotary disc, thus no skidding or axial movement occurring in the cutting process, and sequentially implementing the synchronous linkage between the cutting equipment and the positioning machine.

Description

technical field [0001] The invention relates to the field of metal pipe fitting cutting process equipment, in particular to a positioner for cutting large pipe fittings. Background technique [0002] When plasma or electron beam is used to cut pipe fittings, especially large pipe fittings, positioners are usually used. The existing positioners usually use open gears for transmission, and an opening is opened on the transmission gear, so that the pipes to be cut The pipe fittings are set on the large gear through the opening, and the cutting is realized by rotating and displacing through gear transmission. However, due to the limitation of the manufacturing process, the nominal diameter of the large gear has an upper limit (maximum 1.5 meters), so when cutting large pipe fittings At the same time, the existing open gear transmission method is prone to slipping and axial movement during the working process, and at the same time cannot meet the requirements of automatic cutting...

However, due to the limitation of the manufacturing process, the nominal diameter of the large gear has an upper limit (maximum 1.5 meters), so when cutting large pipe fittings At the same time, the existing open gear transmission method is prone to slipping and axial movement during the working process. At the same time, it cannot meet the requirements of automatic cutting equipment and positioner synchronous linkage, which brings a lot of inconvenience to cutting.
