Description

[0001] APPARATUS FOR MAKING HOLE [0002]

The present invention relates to a hole processing apparatus, and more particularly, to a hole processing apparatus capable of preventing twisting of a gas hose due to rotation of a torch and realizing smooth hole processing.

Generally, during the ship construction, the pipe works through many floor and wall surfaces. At this time, holes are formed on the bottom surface and the wall surface for passing the pipes through the bottom surface and the wall surface, respectively, and pipes are welded to the holes after welding.

In this way, when the pipe passing position is determined in advance and machining is performed, the machining accuracy of the hole is good because the working condition is good. However, when the pipe passing position can not be determined in advance, There is a case where construction is required.

At this time, if the machining surface of the hole is not horizontally placed, the posture of the worker may become unstable, and the installation angle of the machining surface may be unstable, so that an ellipse may be machined on the machined surface. Further, when the holes are manually cut, the degree of the hole-processed surface is poor, and a large gap is generated between the pipe and the hole, so that there is a great difficulty in welding after the welding.

In this connection, "circular hole cutting apparatus (Registration Practical Utility Model No. 20-0338200)"

Conventionally, a circular hole cutting apparatus attaches a tilting base to a work surface to be cut by using a vacuum adsorption pad and a magnet, adjusts the rotation guide mounted on the central axis and the coaxial axis to adjust the position of the cutting torch to a circle size, Cut the hole on the machined surface using the cutting torch.

However, in this conventional technique, since the tilting base is attached to the processing surface through the vacuum adsorption pad and the magnet, if the processing surface is heated by the flame of the torch, thermal deformation occurs in the vacuum adsorption pad or the magnetic force of the magnet is weakened, The tilting base can easily fall off the work surface during machining of the machining surface through the cutting torch.

Further, if the cutting torch supplied with the gas from the gas hose rotates about the center axis of the hole cutting device, the gas hose is twisted, which may be a difficult point in machining the machined surface.
