Abstract
Description
Technical Field
[0001] The utility model relates to the field of welding, in particular to a multifunctional seamless pipe welding auxiliary positioning fixture. Background Art
[0002] Control instrument equipment pipelines are usually made of stainless steel seamless pipes. When arranging the pipelines, if the pipeline runs too long, the straight pipe sections are usually welded. At the same time, the bends and turns of the pipelines are usually connected by welding elbows and straight seamless pipe sections. In addition, when there are branches in the pipeline, welding tees and straight seamless pipe sections are also used for welding. The docking and positioning of the above-mentioned pipeline parts before welding usually use the straight edge of the auxiliary profile as a support, manually align the interfaces of the pipeline parts, and then manually hold them in place or press them down with heavy objects before welding. During this process, the pipeline docking is prone to deviation, and the pipeline parts are prone to displacement during the welding process, which in turn affects the actual welding effect and appearance.

[0015] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.
[0016] like Figure 1 、 Figure 2 As shown, the utility model is a multifunctional seamless pipe welding auxiliary positioning fixture, including a base 1, a pressure cover 2, a first clamping bolt 3 and a second clamping bolt 4. The base 1 is provided with a pressure cover 2, the base 1 is an I-shaped base with a depression in the middle, and the pressure cover 2 is a convex type. The concave and convex parts of the base 1 and the pressure cover 2 are arranged correspondingly, a first clamping bolt 3 is provided in the center of the pressure cover 2, which passes through the pressure cover 2, and second clamping bolts 4 are provided on both sides of the pressure cover 2. The second clamping bolts 4 lock the pressure cover 2 and the upper part of the base 1, wherein the concave and convex parts are set as a first placement position 5, and the first placement position 5 is used to place a straight pipe 9, and the two sides of the I-shaped base 1 are set as second placement positions 6, and the second placement position 6 is used to place an elbow 10 and a tee 11.
[0017] An adjusting gasket set 7 is provided on the side of the I-shaped base 1 , and the adjusting gasket set 7 is used to adjust the centering of the elbow and the tee at the second placement position 6 .
[0018] A locking nut 8 is provided on the second clamping bolt 4 . The locking nut 8 is placed on the gland 2 and is used to fix the gland 2 .
[0019] Before welding the pipeline, this clamp can be used to dock and position the pipeline parts that need to be welded. It is easy to operate, safe and reliable to fix, does not require additional manual assistance, and the pipeline parts will not be displaced during welding, which will affect the pipeline welding effect.
[0020] When the straight pipe sections 9 are connected, the pipeline parts can be placed directly in the V-groove at the top middle of the base 1. First, use the second clamping bolt 4 and the locking nut 8 to fix the gland 2 on the base 1. Then, align the interfaces of the pipeline parts and use the first clamping bolt 3 to tighten the pipeline parts into position. After that, welding operations can be performed.
[0021] When positioning the elbow 10 or tee 11, the piping components can be placed in the U-shaped grooves on both sides. The shim set 7 is adjusted to align them. After the interfaces are aligned, the second clamping bolt 4 is used to clamp the piping components in place. Welding can then be performed. When placing piping components in the U-shaped grooves, appropriate adjustment shim sets 7 can be added based on the outer diameter of the pipe to ensure that the piping components are centered and close to the base 1, preventing displacement of the piping components.
