Problems solved by technology

In the butt welding of hydraulic pipelines, especially the welding of conventional φ76mm hydraulic pipelines, the traditional method is to use manual (TIG) tungsten argon arc welding full argon welding or manual (TIG) tungsten argon arc welding for backing after on-site assembly. Manual electrode arc welding filling and cover welding, but for large-scale technical transformation projects, this welding method is inefficient, labor-intensive, and the quality of the weld is too dependent on the welder's operating skills and experience, and often due to weld quality inspection Unqualified, affecting the quality of online products and the progress of technological transformation

Embodiment 1

[0037] like Figure 1-Figure 5As shown, a hydraulic pipeline pairing device of the present invention is used for the pairing of the grooves 201 opened by the corresponding nozzles of the two sections of the hydraulic pipeline 200, so as to facilitate the welding of the two sections of the hydraulic pipeline 200, and it includes at least two pairings The tooling unit 100, each pair of tooling units 100 includes a fixed base 10 and a movable link mechanism 20, the top of the fixed base 10 is provided with a chute 11; the movable link mechanism 20 includes a sliding arrangement in the chute 11 The sliding seat 21 is provided with a sliding seat adjusting mechanism 29 between one end of the sliding seat 21 and the fixed base 10, and a first connecting rod 22 and a second connecting rod 23 are respectively connected on both sides of the top of the sliding seat 21 through pins 25, The first connecting rod 22 and the second connecting rod 23 have the same specifications, and a bidire...

Embodiment 2

[0044] like Figure 1-Figure 7 As shown in the figure, a hydraulic pipeline group butt welding process of the present invention is used for the group butt welding of the ends of two hydraulic pipelines 200. Taking the hydraulic pipeline 200 with a diameter of 76 mm as an example, the corresponding ends of the two hydraulic pipelines 200 are firstly provided with grooves. After 201, use the hydraulic pipeline grouping device described in Embodiment 1 to group the grooves 201 of the two sections of the hydraulic pipeline 200. First, set the two groups to the tooling units 100 at corresponding intervals to ensure that they are on the same horizontal line. , and then fix the two sections of hydraulic pipelines 200 on the tops of the two pairs of tooling units 100 through the pipeline locking mechanism respectively, and then preliminarily adjust the distance between the two sections of hydraulic pipelines 200 through the sliding seat adjustment mechanism 29, and then through the two...

Abstract

The invention discloses a hydraulic pipeline assembly device which comprises at least two assembly tool units, each assembly tool unit comprises a fixed base and a movable connecting rod mechanism, and a sliding groove is formed in the top of each fixed base; the movable connecting rod mechanism comprises a sliding seat slidably arranged in the sliding groove, a sliding seat adjusting mechanism is arranged between one end of the sliding seat and the fixed base, the two sides of the top of the sliding seat are connected with a first connecting rod and a second connecting rod through pin shafts respectively, and a two-way adjusting mechanism is further arranged between the middle of the first connecting rod or the second connecting rod and the top of the sliding seat. The sliding seat, the first connecting rod, the second connecting rod and the third connecting rod form a parallelogram connecting rod structure, and a pipeline locking mechanism is arranged on the top of the third connecting rod. The hydraulic pipeline assembly welding device is novel in design, reasonable in structure and easy to operate, is matched with the welding technology, effectively achieves automatic assembly welding of hydraulic pipelines, greatly reduces the labor intensity of operators, is short in operation time and has good practicability.

Description

technical field [0001] The invention belongs to the technical field of welding, and relates to a hydraulic pipeline grouping device and a welding process, in particular to a φ 76mm hydraulic pipeline grouping device and a welding process. Background technique [0002] At present, in the upgrading technology transformation of medium and heavy material projects of some large steel enterprises, many transformation focuses include the transformation of hydraulic stations, the group butt welding of a large number of hydraulic pipelines involved in various hydraulic stations, and the pipelines of hydraulic stations are responsible for the transportation of Gas and liquid media of various pressures. In the butt welding of hydraulic pipelines, especially the traditional welding method of conventional φ76mm hydraulic pipelines is to use manual (TIG) tungsten argon arc welding or manual (TIG) tungsten argon arc welding for bottoming after on-site grouping. Manual electrode arc weldin...
