Abstract

The invention discloses an auxiliary device for automatically cutting a long round hole on site. The auxiliary device for automatically cutting the long round hole on site includes a linear drive assembly, an arc drive assembly, a cutting nozzle mounting assembly for clamping a cutting nozzle, and an electric control box; the arc drive assembly is connected to the linear drive assembly, and the linear drive assembly is used for driving the arc drive assembly to perform linear motion; the cutting nozzle mounting assembly is connected to the arc drive assembly, and the arc drive assembly is usedfor driving the cutting nozzle mounting assembly mounted with the cutting nozzle to perform circular motion; and the operation of the linear drive assembly and the arc drive assembly is controlled byan electric control box. The auxiliary device for automatically cutting the long round hole on site is flexible and convenient to use, meets the operation needs of the three-dimensional space on theproduction site, achieves the improvement of processing efficiency and lowering the skill requirements of operators, guarantees the cutting quality of the long round holes on plates of different thicknesses, makes the cutting surface smoother, and only needs simple grinding after cutting to meet the quality specification requirements, which improves the production efficiency and saves the polishing process and time cost.

Description

technical field [0001] The invention relates to the field of welding and cutting, in particular to an auxiliary device for automatically cutting long strips and round holes on site to assist automatic flame or automatic plasma cutting equipment. Background technique [0002] In petrochemical installations, the bolt fixing holes of towers, containers, column bases and the bolt connection holes that need to have adjustment functions in the connecting structural parts need to be processed into long strip bolt fixing holes (that is, long round holes) with a certain length. , to facilitate the installation of bolts. In factory processing, you can rely on CNC cutting machines, profiling cutting machines, etc. to cut and process long strips of round holes, but for the opening of long and heavy profiles, the opening of on-site climbing maintenance construction, etc. Due to construction conditions and other reasons, the cutting machine cannot meet the requirements of hole opening pr...
