Description

Technical Field

[0001] The utility model belongs to the technical field of flange alignment tooling, and in particular relates to a flange multi-hole position alignment tooling. Background Art

[0002] Flange is also called flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used in flanges on equipment inlets and outlets for connection between two devices. Flange connection or flange joint refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a combined sealing structure. Pipe flange refers to the flange used for piping in pipeline devices. When installing existing flanges, it is difficult to align the bolt holes completely when bolting the flanges because the flanges themselves or the pipelines are not convenient to move. The bolts cannot pass through normally, making the installation process cumbersome and time-consuming. Not only is the installation efficiency low, but the installation quality is also difficult to guarantee. Therefore, there is an urgent need for a flange multi-hole alignment tool to solve the above problems. Utility Model Content

[0003] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a flange multi-hole alignment tool.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0005] A flange multi-hole position alignment tool comprises an alignment rod, a conical protrusion is provided on the upper side of the alignment rod, a connecting plate is installed on the top of the conical protrusion, an adjustment sleeve is sleeved on the surface of the alignment rod, and the adjustment sleeve is composed of three arc blocks of the same size and structural shape, the inner sides of the three arc blocks are provided with arc slide grooves matching the conical protrusions, the upper and lower sides of the three arc blocks are provided with installation grooves, and retaining springs are installed in the installation grooves, the alignment rod is sleeved with a connecting rod on the lower side of the adjustment sleeve, and a threaded column is provided at the bottom of the alignment rod, and the threaded column is connected to a locking cap.

[0006] It is further defined that the outer diameter of the adjustment sleeve is processed according to actual use requirements. Such a structural design is convenient for adapting to flanges of different sizes.

[0007] It is further defined that a limit platform is provided on the lower side of the connecting rod. Such a structural design can prevent the connecting rod from falling into the flange hole as a whole after assembly.

[0008] It is further defined that the locking cap has a hexagonal structure, which is convenient for twisting and use.

[0009] It is further defined that the guide rod, the conical protrusion, the connecting plate and the threaded column are integrally formed. Such a structural design improves the structural strength and prolongs the service life.

[0010] The beneficial effects of the utility model are as follows: the utility model provides a guide rod, a conical protrusion, an adjusting sleeve, a connecting rod, a threaded column and a locking cap. When in use, the above parts are assembled and adjusted in sequence, and the adjusting sleeve is inserted into the flange holes on the upper and lower sides. By tightening the locking cap, the conical protrusion can push the adjusting sleeve outward to expand. When the adjusting sleeve expands, it will drive the flanges on the upper and lower sides to move for automatic centering and alignment, so that the bolt holes of the flanges can be quickly aligned, which saves time and effort, is convenient and quick, and improves installation efficiency.

[0016] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-2 As shown, a flange multi-hole position alignment tool of the utility model, a conical protrusion 2 is provided on the upper side of the guide rod 1, a connecting plate 3 is installed on the top of the conical protrusion 2, an adjusting sleeve 4 is sleeved on the surface of the guide rod 1, and the adjusting sleeve 4 is composed of three arc blocks 401 of the same size and structure shape, the inner sides of the three arc blocks 401 are provided with arc slide grooves 402 matching the conical protrusion 2, the upper and lower sides of the three arc blocks 401 are provided with mounting grooves 403, and a retaining spring 404 is installed in the mounting groove 403, the guide rod 1 is sleeved on the lower side of the adjusting sleeve 4, a threaded column 6 is provided at the bottom of the guide rod 1, and the threaded column 6 is connected to a locking cap 7.

[0018] It is further defined that the outer diameter of the adjusting sleeve 4 is processed according to the actual use requirements. Such a structural design is convenient for adapting to the use of flanges of different sizes. In fact, other structural shapes of the adjusting sleeve 4 can also be considered according to specific circumstances.

[0019] Further defined, the lower side of the connecting rod 5 is provided with a limiting platform 8. Such a structural design can prevent the entire connecting rod from falling into the flange hole after assembly. In fact, other limiting structural shapes of the connecting rod 5 can also be considered according to specific circumstances.

[0020] It is further defined that the outer shape of the locking cap 7 is a hexagonal structural design. Such a structural design is convenient for twisting use. In fact, other structural shapes of the locking cap 7 can also be considered according to specific circumstances.

[0021] It is further defined that the guide rod 1, the conical protrusion 2, the connecting plate 3 and the threaded column 6 are integrally formed.
