Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, in particular to a pipe fitting welding tool. Background Art

[0002] Round pipes are widely used in our production and life. They can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry and special purposes.

[0003] During the machining process, it is often necessary to weld pipe fittings, including connecting the ends of two pipe fittings or vertically connecting the pipe fittings to form a T-shaped pipe (i.e., a three-way pipe).

[0004] For the welding of the ends of pipe fittings, the existing welding tools are easy to clamp and fix because the ends of pipe fittings are flat, so the two pipe fittings can be welded after being coaxial. However, for the vertical welding of pipe fittings, there is no better welding tool for clamping. Usually, the welding machine is used after manual gripping. However, manual gripping for welding may cause the two pipe fittings to have different heights during welding, and it will also make it impossible to achieve vertical welding during the welding process. Utility Model Content

[0005] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a pipe welding tool, which can facilitate vertical welding of pipes. Through the first clamping mechanism, the second clamping mechanism and the supporting mechanism, the vertical distribution and fixation of the pipes can be facilitated, which facilitates welding and ensures the quality of welding.

[0006] The utility model is implemented in this way: a pipe welding tool is constructed, comprising a first clamping mechanism, which is arranged at one end of the top of a base, and a second clamping mechanism and a tight seat are arranged at the other end of the top of the base;

[0007] A supporting mechanism is arranged at the middle of the top of the base;

[0008] A plurality of pipes are arranged vertically and fixed by means of a first clamping mechanism, a second clamping mechanism, a tightening seat and a supporting mechanism.

[0009] As described in the previous paragraph, providing the first clamping mechanism and the second clamping mechanism can facilitate fixing of the pipe, and providing the supporting mechanism can facilitate keeping the pipe vertical to the pipe fixed on the first clamping mechanism or the second clamping mechanism, thereby facilitating vertical welding and fixing of the pipe.

[0010] The first clamping mechanism supports and clamps a first pipe, and the second clamping mechanism and the abutting seat support and clamp a second pipe, and the first pipe and the second pipe are kept parallel and at the same height;

[0011] The supporting mechanism is provided with a third pipe fitting, one end of the third pipe fitting is kept perpendicular to the first pipe fitting, and the other end of the third pipe fitting is kept perpendicular to the second pipe fitting.

[0012] Furthermore, the first clamping mechanism is divided into two groups of mechanisms symmetrically arranged, each group of mechanisms includes a mounting block, and a first support block is also arranged on the side surface of one end of the mounting block close to the second clamping mechanism. A U-shaped slot hole is opened on the top of the first support block, and an inclined hole is opened on the mounting block. The first pipe fitting is placed in the U-shaped slot hole of the first support block in the two groups of mechanisms and is kept fixed by passing a pin through the inclined hole and a preset hole at the outer end of the first pipe fitting.

[0013] As described in the previous paragraph, the U-shaped slot on the first support block is convenient for placing pipes, and the inclined holes and latches are convenient for fixing the pipes in the U-shaped slot to prevent the pipes from moving along the opening direction of the U-shaped slot or rotating in the U-shaped slot.

[0014] Furthermore, the second clamping mechanism and the abutting seat are relatively arranged on the other end of the top of the base, and the abutting seat includes a second supporting block and a abutting head, and the abutting head is arranged on the surface of the second supporting block facing the second clamping mechanism.

[0015] Furthermore, the second clamping mechanism includes a bottom plate, which is arranged on the outer side of the base and kept flush;

[0016] A mounting plate is arranged on the bottom plate and has a hinged portion at one end and a sliding portion at the other end;

[0017] A hinged rod, one end of which is hinged to the hinged portion of the mounting plate, and the other end of which is provided with a handle;

[0018] A connecting rod, one end of which is hinged at the middle position of the hinged rod;

[0019] One end of the sliding push rod is hinged to the other end of the connecting rod, and the other end passes through the sliding part of the mounting plate to maintain linear movement.

[0020] As described in the above two paragraphs, the provision of a clamping head and a sliding push rod is to facilitate clamping and fixing of the pipe fitting, so that the pipe fitting remains suspended, thereby facilitating welding.

[0021] Furthermore, a guide block is provided on the base, which is used to install the second clamping mechanism in a precise position, thereby ensuring that the sliding push rod corresponds to the clamping head, one end of the second pipe fitting is clamped at the outer end of the clamping head, and the other end is clamped at the end of the sliding push rod and fixed by the linear movement of the sliding push rod.

[0022] As described in the above paragraph, the guide block is provided to ensure that the positions of the sliding push rod and the abutment head correspond to each other during installation of the second clamping mechanism, thereby achieving suspended clamping of the pipe fitting.

[0023] Furthermore, each group of the support mechanism includes at least a left support block and a right support block, the left support block and the right support block are arranged relative to each other and have corresponding through holes, and the third pipe fitting is placed between the left support block and the right support block and is fixed by inserting a rod through the through hole and a preset through hole at the outer end of the third pipe fitting.

[0024] As described in the previous paragraph, setting the left support block and the right support block can facilitate the left and right direction limitation of the pipe fitting, and setting the insertion rod to pass through the pipe fitting and the support block can ensure the complete fixation of the pipe fitting, thereby facilitating the pipe fitting and the pipe fittings at both ends to be in a vertical state, which is convenient for welding.

[0025] Furthermore, a slag discharge hole is provided at a position of the base close to the first clamping mechanism and the second clamping mechanism.

[0026] As described in the previous paragraph, opening the slag discharge hole can facilitate the rapid discharge of welding slag generated during welding.

[0027] The utility model has the following beneficial effects:

[0028] The welding tool can fix and clamp the pipe fittings through the first clamping mechanism and the second clamping mechanism. Combined with the pipe fittings fixed on the supporting mechanism, it is convenient to vertically arrange and fix the pipe fittings, thereby facilitating welding, effectively ensuring the welding quality, and preventing the pipe fittings from moving or rotating during welding, resulting in the pipe fittings being unable to be vertical after welding, or causing the pipe fittings to have different heights after welding.

[0045] As described in the background technology, the existing pipe welding tooling is only convenient for welding the ends of pipes. It is not convenient for clamping and fixing the vertical welding of pipes, so the welding quality cannot be guaranteed, which may result in failure to ensure verticality and failure to ensure the height consistency of the pipes after welding.

[0062] As described in the above paragraph, the guide block is provided to ensure that the positions of the sliding push rod and the abutment head correspond to each other during installation of the second clamping mechanism, thereby achieving suspended clamping of the pipe fitting.
