[0027] 3. The present invention can assemble the welding rings at the orifice positions of the assembly holes together with the various branch pipes through the welding ring correction assembly. By utilizing this structure, the welding rings can be firstly rounded to prevent axial distortion when the welding rings are sleeved on the outside of the branch pipes. Once distortion occurs, the welding liquid will be uneven during the subsequent welding assembly, which will easily lead to the problem of substandard weld air tightness. Therefore, when assembling the branch pipes, the welding rings can be neatly sleeved on the outside of the branch pipes and assembled together with the axial assembly of the branch pipes, thereby improving the assembly efficiency and the assembly effect.

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0042] Example 1

[0043] like Figure 2 As shown, a main and branch pipe assembly device for stainless steel pipe fittings includes an assembly platform 10.

[0044] The assembly platform 10 is provided with a lower positioning body 11, and a vertical plate 12 is installed on the rear side of the assembly platform 10. An upper positioning body 13 is installed on the vertical plate 12. The upper positioning body 13 is adjustable in vertical position relative to the lower positioning body 11, and the upper positioning body 13 is downwardly coordinated with the lower positioning body 11 to fix the main pipe. The lower positioning body 11 is provided with a main pipe lower positioning structure, and the upper positioning body 13 is provided with a main pipe lower positioning structure. The vertical plate 12 is provided with a vertical guide groove, and the upper positioning body 13 slides in the vertical guide groove. A quick pressing clamp 121 is installed on the vertical plate 12, and the quick pressing clamp 121 is used to drive the upper positioning body 13 to be adjustable in vertical position relative to the lower positioning body 11. Figure 10 As shown, the main pipe lower positioning structure and the main pipe upper positioning structure both include a main pipe positioning groove 103 and an outer flange positioning groove 104 , and the outer flange positioning groove 104 of the main pipe upper positioning structure is a U-shaped structure.

[0045] The upper positioning body 13 is driven downward by the quick pressing clamp 121 to press and fix the main pipe installed through the positioning structure under the main pipe. During the downward process, the U-shaped structure of the outer flange positioning groove 104 will guide and center the outer flange, which is convenient for accurately positioning and fixing the main pipe and ensuring the position of the assembly hole on the main pipe.

[0046] The assembly platform 10 is also equipped with a special-shaped branch pipe moving seat 14 and a straight branch pipe moving seat 15. The special-shaped branch pipe moving seat 14 and the straight branch pipe moving seat 15 slide relative to the assembly platform 10. The special-shaped branch pipe moving seat 14 is provided with a special-shaped pipe positioning structure 141, and the straight branch pipe moving seat 15 is provided with a straight branch pipe positioning structure 151.

[0047] Among them, the assembly platform 10 is equipped with a guide platform 101 for the vertical main pipe and a quick pressing clamp 102. The special-shaped branch pipe moving seat 14 and the straight branch pipe moving seat 15 are slidably fitted on the guide platform 101. The quick pressing clamp 102 drives the special-shaped branch pipe moving seat 14 and the straight branch pipe moving seat 15 to move closer to or away from the main pipe.

[0048] Since one end of the main pipe has an elbow area, under the action of gravity, the main pipe (especially the outer flange) on the lower positioning body 11 will not be in a horizontal state when it is rotated upward. The special-shaped branch pipe is installed on the special-shaped branch pipe moving seat 14, and the straight branch pipe is installed on the straight branch pipe moving seat 15. The special-shaped branch pipe moving seat 14 and the straight branch pipe moving seat 15 are moved along the corresponding guide platform 101 by the quick pressing clamp 102, so that the assembly operation of each branch pipe can be quickly realized with high efficiency and high assembly accuracy.

[0049] Example 2

[0050] Based on the above embodiment, the following improvements are made: Figure 3 、 Figure 4As shown, a fixed seat 142 is installed on the special-shaped branch pipe moving seat 14, and the fixed seat 142 is vertically arranged. The fixed seat 142 is located on the side of the special-shaped branch pipe moving seat 14 away from the upper positioning body 13. A slide groove of a vertical main pipe is provided on the special-shaped branch pipe moving seat 14, and a slide plate 143 is slidably fitted in the slide groove. A spring is installed between the slide plate 143 and the fixed seat 142, and the slide plate 143 is used to limit the top position of the special-shaped branch pipe.

[0051] Since the exposed length of the special-shaped end of the special-shaped branch pipe is limited, generally about 10 mm, the special-shaped branch pipe positioning structure 141 on the special-shaped branch pipe moving seat 14 cannot effectively ensure the stability of the special-shaped branch pipe during assembly. Therefore, the slide plate 143 can effectively fix the special-shaped branch pipe to ensure the stability of the state during axial assembly and the assembly accuracy of the branch pipe.

[0052] Example 3

[0053] Based on the above embodiment, the following improvements are made: Figures 5 to 9 As shown, the welding ring correction assembly 20 includes a movable piece 1 21 and a movable piece 2 22. The movable piece 2 22 is located on the side of the movable piece 1 21 away from the main pipe, and a welding ring holding slot 23 is provided on the side of the movable piece 2 22 opposite to the movable piece 1 21. The top of the welding ring holding slot 23 is open, and the movable piece 1 21 and the movable piece 2 22 are both symmetrically arranged in two groups.

[0054] A sliding pin 24 is provided at the bottom of the movable piece 21, and a slide groove 25 arranged parallel to the main pipe is provided on the assembly platform 10. The sliding pin 24 is slidably installed inside the slide groove 25. The slide groove 25 includes a notch 1 arranged perpendicular to the main pipe and a notch 2 arranged parallel to the main pipe. One end of the notch 2 intersects with one end of the notch 1. The sliding pin 24 is connected to the assembly platform through a spring.

[0055] A second sliding pin 27 is provided at the bottom of the second movable piece 22 , and a second slide groove 26 vertically arranged on the main pipe is provided on the assembly platform 10 , and the second sliding pin 27 is slidably installed inside the second slide groove 26 .

[0056] An elastic block 28 is provided on one side of the movable seat close to the main pipe. The elastic block 28 is elastically deformed before the spring on the sliding pin 24 is elastically deformed, thereby completing the welding ring sleeve on the outer wall of the branch pipe.

[0057] When the movable seat approaches the main pipe, the movable piece 2 22 presses the welding ring inside the welding ring receiving notch 23 onto the movable piece 1 21 to complete the full circle.

[0058] The welding ring is placed from the top of the welding ring holding slot 23. When the movable seat approaches the main pipe, the movable seat will drive the movable piece 22 to approach the main pipe. In the process of approaching the main pipe, the welding ring will be first processed into a whole circle. Since the originally manufactured circular ring is an open ring structure, there is an axial deviation in the circumferential direction, so this step is required. Secondly, the movable piece 22 will squeeze the elastic block 28 under the obstruction of the movable piece 1 21, so that the movable piece 1 21 and the movable piece 22 will fit the whole circle of the welding ring on the branch pipe until the elastic block 28 undergoes the maximum elastic deformation to complete the welding ring fitting.

[0059] When the assembly action is completed, the movable piece 1 21 and the movable piece 22 will move closer to the main pipe together with the movable seat. When approaching the main pipe, the sliding pin 1 24 will be stretched by the spring installed on itself. When it enters the end of the slot 1, it will be pulled, so that the movable piece 1 21 will be separated from the movable piece 2 22. When the movable piece 2 22 is separated, the elastic block 28 will push the welding ring to the side close to the main pipe and fit it on the end face of the assembly hole.

[0060] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
