A multi-functional special-shaped nuclear industry pipe rotation matching device

Abstract

The invention relates to a multi-functional special-shaped nuclear industry pipe rotation matching device, which includes a first roller, a second roller, a third roller and an infrared photoelectric sensor. The first roller rotates around the first rotation axis, the second roller rotates around the second rotation axis, and the third roller rotates around the third rotation axis. The first rotating shaft and the third rotating shaft are arranged symmetrically on both sides of the second rotating shaft, and the first rotating shaft, the second rotating shaft and the third rotating shaft respectively support three different surfaces of the special-shaped nuclear industry pipe. Among them, 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 cross-section of the special-shaped nuclear industry pipe are all equal and remain unchanged, which ensures that the special-shaped nuclear industry pipe can be rotated during the rotation process. The center of gravity is always kept unchanged, which effectively improves the stability during the rotary cutting process of special-shaped nuclear industrial tubes, avoids shaking during the cutting process of special-shaped nuclear industrial tubes and changes the cutting angle, and improves the cutting quality of special-shaped nuclear industrial tubes.

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...
