Automatic following, lifting and pneumatic supporting device and laser pipe cutting machine with device

Abstract

The invention discloses an automatic following, lifting and pneumatic supporting device and a laser pipe cutting machine with the device, and belongs to the field of laser devices. The supporting device comprises a supporting arm assembly, an idler wheel assembly and one or more air cylinders, and the air cylinders are controlled by pneumatic electromagnetic valves; the supporting arm assembly isa telescopic arm; the telescopic arm is hinged to a base and is further hinged to air cylinder shafts; the idler wheel assembly comprises an idler wheel with a V-shaped groove, an idler wheel shaft and an idler wheel axial adjustment mechanism; the idler wheel shaft is arranged at the tail end of the telescopic arm, the idler wheel is rotatably arranged on the idler wheel shaft, and the idler wheel axial adjustment mechanism used for adjusting the axial position of the V-shaped groove in the idler wheel is arranged on the idler wheel shaft. The automatic following, lifting and pneumatic supporting device is simple in structure, low in cost, high in efficiency, remarkable in synergy and convenient to assemble, and can be added in a new pipe cutting machine, and the existing pipe cutting machine on the market can also be updated and remoulded conveniently.

Description

technical field [0001] The invention relates to the field of mechanism equipment, in particular to an automatic follow-up lifting pneumatic support device and a laser pipe cutting machine including the device. Background technique [0002] Due to the high processing efficiency of laser pipe cutting machine, it is widely used in the field of machinery. However, the steel pipe processed by the laser pipe cutting machine is relatively long (up to 6 meters), the pipe wall is relatively thin, and the pipe diameter is different (mainly for the processing of various thin-walled round pipes within φ50, and also for the processing of φ50-200 round pipes). [0003] In the process of processing, when the distance between the front and rear chucks is far away, the steel pipe itself is not rigid enough to cause the steel pipe to bend down and deflect when turning, which makes the center of the round pipe deviate from the center position, thus affecting the position accuracy of the front ...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology, it is difficult to add intermediate support in the middle and the support cannot adapt to different diameters in the existing technology due to the different diameters of the processing pipes and the front and rear chucks of the laser pipe cutting machine from the farthest six meters to zero with the processing process. The problem that the pipe diameter cannot be aligned with the pipe, the invention provides an automatic follow-up lifting pneumatic support device and a laser pipe cutting machine including the device
