Technical Field
The utility model relates to the technical field of flanges, in particular to a flange with auxiliary positioning.
Background
Flanges are parts that interconnect pipes to pipes and to valves, and are attached to the ends of the pipes. The flanges are generally used in pairs, and the pair of flanges are connected with the pipeline well by arranging the corresponding mounting holes and penetrating the mounting holes through connecting pieces such as bolts. The flanges are provided with holes, the two flanges are tightly connected through bolts, and the flanges are sealed through sealing rings; flanges are typically welded directly to pipes, valves, etc. and then bolted together to join the components.
When the existing flanges are connected, the mounting holes in the adjacent flanges are difficult to be concentric, the flanges are often rotated to be concentric to the mounting holes through tools such as bolts after connection, and the sealing rings between the flanges are easily stressed and pulled in the rotating process, so that the phenomena of deformation, dislocation, separation and the like of the sealing rings are caused, and the sealing property between the flanges is influenced.
Disclosure of Invention
In order to overcome the defects of the background art, the utility model aims to design the flange with the auxiliary positioning function, and the main flange body and the auxiliary flange body can be well calibrated when being spliced together through the limiting of the positioning column and the guiding groove, so that the sealing ring is naturally fixed between the main flange body and the auxiliary flange body, and the sealing property is ensured.
The technical scheme adopted by the utility model is as follows: the utility model provides a flange with auxiliary positioning, includes main flange body and vice flange body, and main flange body and vice flange body are connected, the central authorities of main flange body, vice flange body are equipped with the through-hole, are equipped with first connecting hole on the main flange body, are equipped with on the vice flange body with first connecting hole assorted second connecting hole, be equipped with on the main flange body with second connecting hole assorted reference column, be equipped with the guiding groove on the vice flange body, and the second connecting hole all is in the guiding groove.
Furthermore, the main flange body is provided with more than two positioning columns and first connecting holes, and the positioning columns are fixed between the two adjacent first connecting holes.
Furthermore, the main flange body is provided with four positioning columns and four first connecting holes, and each positioning column is fixed between two adjacent first connecting holes.
Furthermore, the positioning column and the first connecting hole have the same length from the center point of the through hole.
Adopt above-mentioned technical scheme, in main flange body and vice flange body installation, if first connecting hole and second connecting hole are not concentric, the reference column preferentially contacts the guiding groove on the surface, it is rotatory with main flange body, it is close to towards the direction of second connecting hole to make the reference column through the guide of guiding groove, it is downthehole until the reference column enters into the second connecting hole, remaining first connecting hole and second connecting hole align with each other with one heart this moment, make main flange body and vice flange body concatenation just can calibrate the connecting hole when being in one-tenth, make the sealing washer fix naturally between main flange body and vice flange body, thereby guarantee the leakproofness, thereby easy to assemble improves the installation effectiveness.
The utility model is further arranged that one end of the positioning column facing the auxiliary flange body is an arc surface and the side surface is a drawing surface.
Furthermore, the guiding groove is a spherical groove, and a round chamfer is arranged at the joint between the second connecting hole and the guiding groove.
By adopting the technical scheme, the outer diameter of the positioning column is gradually increased from outside to inside, the largest outer diameter is the same as the second connecting hole, the positioning column is convenient to position in the installation process, and the guide groove is a spherical groove processed by a spherical cutter, so that the positioning column is convenient to process and is suitable for batch production.
The embodiments of the present invention will be further described with reference to the accompanying drawings.

Detailed Description
As shown in fig. 1 to 4, a flange with auxiliary positioning includes a main flange body 1 and an auxiliary flange body 2, the main flange body 1 is connected with the auxiliary flange body 2, a through hole 3 is provided at the center of the main flange body 1 and the auxiliary flange body 2, a first connection hole 11 is provided on the main flange body 1, a second connection hole 21 matched with the first connection hole 11 is provided on the auxiliary flange body 2, a positioning column 4 matched with the second connection hole 21 is provided on the main flange body 1, a guide groove 23 is provided on the auxiliary flange body 2, and the second connection holes 21 are all in the guide groove 23. Furthermore, the main flange body 1 is provided with more than two positioning columns 4 and first connecting holes 11, and the positioning columns 4 are fixed between two adjacent first connecting holes 11. Furthermore, four positioning columns 4 and four first connection holes 11 are arranged on the main flange body 1, and each positioning column 4 is fixed between two adjacent first connection holes 11. Furthermore, the positioning column 4 and the first connecting hole 11 have the same length from the center point of the through hole 3.
