Multifunctional special-shaped nuclear industrial pipe running fit device

Abstract

The invention relates to a multifunctional special-shaped nuclear industrial pipe running fit device. The device comprises a first roller, a second roller, a third roller and an infrared photoelectric sensor. The first roller rotates around a first rotating shaft, the second roller rotates around a second rotating shaft, and the third roller rotates around a third rotating shaft. The first rotating shaft and the third rotating shaft are symmetrically arranged on the two sides of the second rotating shaft, and the first rotating shaft, the second rotating shaft and the third rotating shaft support three different faces of a special-shaped nuclear industrial pipe correspondingly. The distances from the axis of the first rotating shaft, the axis of the second rotating shaft and the axis of the third rotating shaft to the center point of the section of the special-shaped nuclear industrial pipe are equal and are kept unchanged, it is guaranteed that the gravity center of the special-shaped nuclear industrial pipe is kept unchanged all the time in the rotating process, and the stability of the special-shaped nuclear industrial pipe in the rotating cutting process is effectively improved. The cutting angle is prevented from being changed due to shaking in the cutting process of the special-shaped nuclear industrial pipe, and the cutting quality of the special-shaped nuclear industrial pipe is improved.

Description

technical field [0001] The invention relates to the technical field of special-shaped nuclear industry pipe processing, in particular to a multifunctional special-shaped nuclear industry pipe rotation matching device. Background technique [0002] At present, for nuclear industry pipes with thick-walled pipes, cutting knives are commonly used, or magnetic pipe cutting machines are used for cutting, which adjust the intake of oxygen and acetylene according to the thickness of nuclear industry pipes, so as to achieve the cutting of pipes . However, for nuclear industry pipes with thick walls or large diameters, when cutting with a cutter, people need to change the cutting angle constantly, and the final pipe bevel presented is not uniform, and the workmanship is poor in appearance. However, if the cutting angle is changed by rotating the nuclear industry pipe, since the shape of the nuclear industry pipe is mostly polygonal, the traditional rotating support and matching devic...
