Description

  The present invention relates to a three-dimensional pipe assembling apparatus for accurately attaching a flange at a predetermined angle to an end of a pipe with a bent pipe or a branch pipe, and in particular, a three-dimensional suitable for application to a lubricating oil pipe or the like in a mechanical device or the like. The present invention relates to a pipe assembly apparatus.

As a three-dimensional pipe assembly apparatus for accurately attaching a flange at a straight angle to the end of a pipe such as a straight pipe or a bent pipe, there are those described in Patent Document 1 and Patent Document 2 below.
Each of these assumes the case where the mounting angle of the flange with respect to the shape of the entire pipe is a right angle.
Therefore, when the flanges are located on the same plane, or assuming a three-dimensional arrangement such as a vertical direction and a horizontal direction, but obliquely with respect to the horizontal and vertical directions, that is, having an angle. Not assumed.

That is, for example, in a three-dimensional pipe as shown in FIG. 5 to FIG. 6, in order to fix and weld the flange at the end at an accurate square angle with respect to the axis of the pipe, It is necessary to continue assembling while measuring repeatedly using a welding ruler, a deposit, a level, etc.
At this time, even if the dimensional error is very slight, when the end of the long pipe is reached, the error has a great influence, and it may be difficult to connect to the adjacent pipe.

In the conventional three-dimensional pipe assembly method, it is suitable for accurately attaching a flange to a horizontal or vertical pipe, but to attach a flange to an oblique pipe accurately in the direction perpendicular to the axis, (1) Accurate positioning cannot be achieved simply by using a flange welding ruler, insert, level, etc. (2) Even if an angle gauge such as a protractor is used, it is repeated to match the position and angle accurately. It takes time to work because it is a work while measuring. (3) The accuracy varies depending on the skill of the worker. (4) It is difficult to match the relative position of the flanges for long dimension pipes. 5) There were drawbacks such as requiring two or more workers.
