Description

Piping jig with pipe alignment function

The present invention relates to a jig for pipe fitting having a pipe alignment function.

Pipe welding refers to welding the distal end of the first pipe and the distal end of the second pipe in contact with each other so that the first pipe and the second pipe, which are two pipes, are connected.

Temporary welding of the pipe is a welding site in order to prevent bending or twisting of at least one of the first pipe and the second pipe due to heat applied during welding to the first pipe and the second pipe. It refers to performing a plurality of point welding so as to be spaced apart from the abutting portions of the first pipe and the second pipe.

In general, for the temporary welding of the pipe, the first pipe and the second pipe are fixed, and a temporary welding jig is applied so that the temporary welding of the pipe is performed. These are those of the patent literature presented below, including the patents registered by

However, according to the conventional temporary welding jig including the patent document presented below, only the temporary welding of the first pipe and the second pipe is performed, and the alignment of the first pipe and the second pipe is directly performed by an operator manually. Alignment or a separate alignment jig is used. When the operator aligns, the alignment state is different depending on the skill level of the operator, and when the separate alignment jig is used, the alignment of the first pipe and the second pipe Then, there was a problem in that the alignment of the first pipe and the second pipe was misaligned due to the separation of the separate alignment jig for mounting the conventional jig for temporary welding.

The pipe protrusion length adjustment member is
a pipe protrusion length adjustment body disposed parallel to the first body member on a side of the first body member facing the second body member;
A pipe protrusion length adjustment bend body extending from the distal end of the pipe protrusion length adjustment body and formed in a bent shape along a direction away from the first body member relatively;
and a pipe protrusion length adjustment connecting shaft rotatably connecting the pipe protrusion length adjustment body to the first body member,
When the first pipe is inserted through the first body member, the length of the protrusion of the first pipe with respect to the first body member by protruding and fixing the first pipe to the end of the pipe protrusion length adjustment bending body A jig for pipe welding with a pipe alignment function, characterized in that it can be adjusted to a predetermined length. delete The method of claim 1,
The welding torch includes a torch body that can be held by hand, a torch head formed to be bent at a predetermined angle with respect to the torch body at the end of the torch body, and a ceramic nozzle connected to the end of the torch head and made of a ceramic material; , a tungsten rod formed to have a long predetermined length, disposed inside the ceramic nozzle and the torch head, and in contact with the first pipe and the second pipe to perform the welding; and a tungsten rod fixture disposed at the distal end in the opposite direction and capable of fixing the tungsten rod disposed inside the ceramic nozzle and the torch head,
The jig for pipe welding having the pipe alignment function is
It is formed on at least one of the first body member and the second body, and the end of the ceramic nozzle and the end portion of the ceramic nozzle are formed so as to be in contact with each other among the distal end portions of the first pipe and the distal end of the second pipe that face each other. Including; a tungsten rod positioning member capable of adjusting the separation distance between the ends of the tungsten rod;
The tungsten rod positioning member is
a nozzle insertion hole that is recessed to a predetermined depth in an upper surface of at least one of the first upper pipe support body and the second upper pipe support body, and into which the distal end of the ceramic nozzle can be inserted;
and a tungsten rod seating protrusion protruding from the bottom of the nozzle insertion hole at a predetermined height to seat the end of the tungsten rod,
When the distal end of the ceramic nozzle is inserted into the nozzle insertion hole in a state in which the tungsten rod is movably inserted into the ceramic nozzle and the torch head, the distal end of the tungsten rod is seated on the tungsten rod seating protrusion and the ceramic nozzle is movably inserted. The separation distance between the end of the nozzle and the end of the tungsten rod can be adjusted to a predetermined separation distance,
By applying an external force to the tungsten rod fixture to fix the position of the tungsten rod in a state where the separation distance between the end of the ceramic nozzle and the end of the tungsten rod is adjusted to a predetermined separation distance, the end of the ceramic nozzle and the tungsten rod A pipe fitting jig with a pipe alignment function, characterized in that the separation distance between the ends of the rods can be maintained in a state adjusted to a predetermined separation distance. delete The method of claim 1,
The jig for pipe welding having the pipe alignment function is
Occurs when performing the temporary welding by covering the distal end of the first pipe and the distal end of the second pipe together when the temporary welding is performed on a portion in contact with each other among the distal end of the first pipe and the distal end of the second pipe Including;
The fire scattering prevention member is
an upper cover body formed to cover a portion of the distal end of the first pipe and the distal end of the second pipe and having both sides open;
The lower cover is formed to cover the remaining portions except for the portion covered by the upper cover body among the distal end of the first pipe and the distal end of the second pipe that are in contact with each other, both sides are open and the lower cover is connected to the upper cover body body and
a welding torch inlet formed through at least one of the upper cover body and the lower cover body, and into which the welding torch is inserted;
A pair of upper cover collets coupled to both open side surfaces of the upper cover body and having a curved surface of a predetermined curvature at the lower portion thereof;
A pair of lower cover collets coupled to both open sides of the lower cover body and having a curved surface of a predetermined curvature formed thereon,
A portion connected to the upper cover body and the lower cover body is made of a magnet and is detachably connected to each other,
In a state in which the distal end of the first pipe and the distal end of the second pipe are covered by the upper cover body and the lower cover body, the welding torch is put into the welding torch inlet to perform the temporary welding, so that of the first pipe The temporary welding of the distal end and the distal end of the second pipe is made, but the scattering of the sparks generated during the temporary welding can be prevented.
