Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding tooling technology, and in particular to a welding assembly tooling for pipe fittings. Background Technology
[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. In the production and construction of steel structures, it is often necessary to weld two steel components. Before welding, not only must the welding area be cleaned, but also tooling and fixtures must be used for positioning and fixing to ensure the precision and quality of the weld.
[0003] In the construction and erection of steel components, the main structure has mostly been prefabricated through digital modeling, and these prefabricated components can be installed by hoisting. However, welding is still required during construction, whether it is welding of steel components or welding and erection of construction facilities / protection. This utility model provides a welding fixture for assembling pipe fittings. Utility Model Content
[0004] This utility model discloses a welding assembly fixture for pipe fittings, including a first clamping member, a second clamping member, a third clamping member, and a fourth clamping member. The first and second clamping members form a first set of clamps, and the third and fourth clamping members form a second set of clamps. First screws are inserted and arranged on both sides of the first and second sets of clamps. In use, the first set of clamps is used to clamp one pipe fitting, and the second set of clamps is used to clamp another pipe fitting.
[0005] A second screw is inserted into the fourth clamping member, and the second screw is threadedly connected to the second clamping member. Several smooth rods are fixedly connected to the third clamping member, and the smooth rods are slidably connected to the first clamping member. The axis of the second screw is parallel to the axis of the smooth rod. When the first screw is tightened, the two pipe fittings are aligned coaxially with the axis and the smooth rods. Simultaneously, the second screw is rotated to control the distance between the first and second sets of clamps, thus controlling the distance between the two pipe fittings and meeting welding requirements.
[0006] Preferably, the first screw has an elongated hole in its middle, and a limiting ring is inserted through the elongated hole. The first screw, the second clamping member, and the fourth clamping member are inserted through each other and threadedly connected to the first clamping member and the third clamping member, respectively. The limiting ring is provided to prevent the first screw from separating from the second / fourth clamping member.
[0007] Preferably, both the first and second sets of clamps are equipped with pull ropes. The pull ropes ensure that the first and second clamping parts, the third clamping part, and the fourth clamping part do not separate, which facilitates the use of the tooling.
[0008] Preferably, the first, second, third, and fourth clamping members are all provided with a fastening groove, and a fastening block is provided in the fastening groove, with the fastening block fastening the end of the pull rope. The pull rope is fixed by the fastening block.
[0009] The beneficial effects of this utility model are as follows: 1. This utility model has a simple structure and is easy to carry. It is also equipped with limit rings, pull ropes and other components to ensure that all parts of the tooling are connected together and easy to use.
[0010] 2. It can clamp the end sidewalls of two pipe fittings. By setting the second screw and the smooth rod, the coaxiality and spacing of the pipe fittings can be adjusted to meet the needs of assembly welding. Attached Figure Description

[0013] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.
[0014] like Figures 1 to 4As shown, a welding assembly tooling for pipe fittings includes a first clamping member 1, a second clamping member 2, a third clamping member 5, and a fourth clamping member 6. Their main structures are all identical and are arc-shaped. The first clamping member 1 and the second clamping member 2 form the first set of clamps, and the third clamping member 5 and the fourth clamping member 6 form the second set of clamps. First screws 4 are inserted on both sides of the first set of clamps and the second set of clamps. It can be understood that the first set of clamps, together with the first screws 4, or the second set of clamps, together with the first screws 4, forms a clamping structure. In use, the first set of clamps and the second set of clamps respectively clamp and fix the end sidewalls of the two pipe fittings.
[0015] A second screw 7 is inserted into the fourth clamping member 6, and the second screw 7 is threadedly connected to the second clamping member 2. Several smooth rods 3 are fixedly connected to the third clamping member 5. The smooth rods 3 are used for guidance. The smooth rods 3 are slidably connected to the first clamping member 1. The axis of the second screw 7 is parallel to the axis of the smooth rod 3. It should be noted that when the first set of clamps and the second set of clamps are used to clamp the pipe fittings, the second screw 7 is engaged with the second clamping member 2, while the smooth rods 3 are engaged with the first clamping member 1. That is, after the first set of clamps and the second set of clamps are used to fix the pipe fittings, it can be ensured that the two pipe fittings can be set coaxially. At this time, the second screw 7 is rotated with a tool to control the distance between the two pipe fittings, which is conducive to the assembly and welding of the device.
[0016] The first screw 4 has an elongated hole 8 in the middle, and a limiting ring 9 is inserted through the elongated hole 8. The limiting ring 9 is located between the first clamping member 1 and the second clamping member 2, and between the third clamping member 5 and the fourth clamping member 6. Since the screw 4 and the second / fourth clamping member 2 are inserted through each other, the limiting ring 9 is set to prevent loss and facilitate the use of the tooling.
[0017] Both the first and second clamping units are equipped with pull cords 10. The pull cords 10 connect the components of the first and second clamping units together, thus preventing loss.
[0018] Each of the first clamping member 1, the second clamping member 2, the third clamping member 5, and the fourth clamping member 6 is provided with a fastening groove, and a fastening block 11 is provided in the fastening groove, and the fastening block 11 fastens the end of the pull rope 10. That is, the first clamping member 1 and the second clamping member 2 are connected together by the pull rope 10, and the third clamping member 5 and the fourth clamping member 6 are connected together by the pull rope 19. The structure of the fastening block 11 and the groove is to fix the pull rope 10.
[0019] Working principle: In the initial state of the tooling, the first screw 4 is not connected to the first clamping part 1 / third clamping part 5, while the second screw 7 is fitted to the second clamping part 2, and the bare rod 3 is fitted to the first clamping part 1. At this time, the first clamping part 1 or the second clamping part 2 is placed against the side wall of one pipe fitting, and the third clamping part 5 or the fourth clamping part 6 is placed against the side wall of another pipe fitting. Then, the other half of the first set of clamps and the second set of clamps are clamped together and screwed onto the first screw 4 to form a tight clamp structure. After all the first screws 4 are threadedly connected, they are tightened to set up the tooling for the two pipe fittings. Then, the second screw 7 is rotated to adjust the distance between the two pipe fittings. Finally, welding is performed. A portion can be pre-welded, and then the tooling can be disassembled to weld the remaining portion.
[0020] The technical means disclosed in this utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
