Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the word "over" a first feature or feature in a second feature may include the word "over" or "over" the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature "under" a second feature may include a first feature that is directly under and obliquely under the second feature, or may simply mean that the first feature is at a lesser elevation than the second feature.
As shown in fig. 1 to 4, the auxiliary welding fixture 1 of the instrument mounting base 2 of the present embodiment includes a handrail 11, a connecting rod 12, a limiting portion 13 and a positioning rod 14, the handrail 11 is perpendicularly connected to the connecting rod 12, the limiting portion 13 is disposed between the connecting rod 12 and the positioning rod 14, the positioning rod 14 is insertable into a through hole 21 of the instrument mounting base 2, the limiting portion 13 is connected to the instrument mounting base 2, so that one end of the positioning rod 14, which is far away from the limiting portion 13, extends out of the through hole 21 and the positioning rod 14 and the instrument mounting base 2 are kept relatively stationary.
The welding auxiliary tool 1 of the instrument mounting base 2 of the embodiment extends the positioning rod 14 out of the through hole 21 of the instrument mounting base 2 through the limiting function of the limiting part 13, so that the positioning rod 14 can be inserted into the opening hole 101 of the pipeline 100, the instrument mounting base 2 is accurately positioned on the opening hole 101 of the pipeline 100, and the through hole 21 of the instrument mounting base 2 is aligned with the opening hole 101 of the pipeline 100. In addition, through setting up connecting rod 12, effectively prolonged the distance of holding hand and welding seam 200, prevented to take place the wounded condition of hand among the welding process.
Preferably, the stopper 13 is provided with an external thread, and the stopper 13 is screwed with an internal thread provided in the through hole 21. The instrument mounting base 2 is generally self-threaded due to the need to mount instruments thereon. This embodiment can realize welding auxiliary fixtures 1 and instrument mount 2 through the dismantlement of threaded connection form and be connected through the external screw thread that sets up the internal thread matching on spacing portion 13 and instrument mount 2 to make welding auxiliary fixtures 1 and instrument mount 2 can fasten the assembly together, conveniently carry out the location before welding to instrument mount 2.
Further, the external thread on the limiting part 13 is a tapered thread. Because the instrument installation has higher requirement to the leakproofness, the screw thread on the instrument mount pad 2 often sets up the better toper screw thread of sealing performance, consequently sets up the external screw thread on spacing portion 13 also to the toper screw thread in order to match with the screw thread on the instrument mount pad 2.
As shown in fig. 5 and 6, in some preferred embodiments, the limiting portion 13 is shaped like a cake, the diameter of the limiting portion 13 is larger than that of the through hole 21, and the limiting portion 13 abuts against one end of the instrument mounting base 2 to extend the positioning rod 14 out of the through hole 21 by a certain distance, so that the positioning rod 14 performs a positioning function. Compared with a complex thread structure, the processing difficulty of the limiting part 13 is greatly reduced, and the manufacturing cost is saved.
further, spacing portion 13 is the magnetic part, makes instrument mount pad 2 can be adsorbed and fix on spacing portion 13 to make instrument mount pad 2 combine as an organic whole with welding auxiliary fixtures 1, in instrument mount pad 2's location process, need not to hold instrument mount pad 2 with the hand, prevent to hinder the hand because of the welding position is too close.
In other preferred embodiments, as shown in fig. 7 and 8, the position-limiting portion 13 includes a bottom plate 131 and a side wall 132, the bottom plate 131 is perpendicular to the connecting rod 12, the side wall 132 is a hollow cylinder, the side wall 132 is perpendicular to the bottom plate 131 and is located on the side of the bottom plate 131 away from the grab bar 11, and the side wall 132 is provided with an internal thread matching with the external thread on the instrument mounting base 2. When the screw thread on instrument mount pad 2 is the external screw thread form rather than the internal screw thread form, the internal screw thread that sets up on lateral wall 132 can carry out threaded connection with instrument mount pad 2 that is provided with the external screw thread to realize welding auxiliary fixtures 1 and instrument mount pad 2's detachable connection.
further, the internal threads provided on the side wall 132 are tapered threads. When the external screw thread on instrument mount pad 2 was the toper screw thread, also set up the internal thread on lateral wall 132 to the assembly of convenient welding auxiliary fixtures 1 and instrument mount pad 2 for the toper screw thread.
Preferably, the length of the connecting rod 12 is not less than 5 CM. Because the outer diameter of the positioning rod 14 cannot be perfectly matched with the aperture of the opening 101, a small gap exists between the positioning rod 14 and the hole wall of the opening 101, and before the instrument mounting base 2 is welded and fixed, the hand holding rod 11 needs to be held by hand, so that the axis of the instrument mounting base 2 is aligned with the central line of the pipeline 100. The connecting rod 12 is set to be not shorter than 5CM in length, so that a sufficient distance is kept between the welding seam 200 and the handrail 11, and hands can be effectively prevented from being burnt by heat generated by welding.
Preferably, the axes of the connecting rod 12, the limiting part 13 and the positioning rod 14 are overlapped, so that the welding auxiliary tool 1 is convenient to process and use.
The embodiment of the invention also provides a welding method of the instrument mounting base 2, which comprises the following steps:
Firstly, assembling the instrument mounting seat 2 on the welding auxiliary tool 1, then inserting the positioning rod 14 into the opening 101 on the pipeline 100, then fixing the instrument mounting seat 2 by spot welding, then separating the welding auxiliary tool 1 from the instrument mounting seat 2, and after the separation is finished, welding the instrument mounting seat 2 and the pipeline 100. By utilizing the characteristic of detachable connection of the welding auxiliary tool 1 and the instrument mounting seat 2 and adopting a two-step welding method of spot welding and full welding, the welding auxiliary tool 1 is separated after the positioning of the instrument mounting seat 2 is completed, so that the welding auxiliary tool 1 is prevented from being damaged by heat generated by welding and even the welding auxiliary tool 1 and the instrument mounting seat 2 are prevented from being welded. Therefore, the welding method of the instrument mounting base 2 of the embodiment has low welding difficulty and high precision.
