The end face of the flange needs to be coaxially fitted with the end face of the pipe and then welded. It is difficult to position flanges and pipes with larger diameters. When the flange is installed, it will not be coaxial with the pipe, resulting in a loose flange connection and a risk of leakage. To address the above problems, a flange positioning tool is proposed.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1

[0023] like Figure 1-3 As shown, the utility model provides a flange positioning tool, including a fixed shell 1 and a fixed seat 2, a fixing mechanism 3 is arranged on one side of the fixed seat 2, the fixing mechanism 3 includes a fixed disk 31, a screw 32 and six groups of connecting rods 36, one end of the screw 32 is fixedly installed with a connecting ring 33, the outer wall of the screw 32 is threadedly connected with a connecting sleeve 34, one end of the connecting sleeve 34 is fixedly installed with a connecting disk 35, one end of every two groups of connecting rods 36 is provided with a connecting shell 37, the interiors of the three groups of connecting shells 37 are rotatably connected with two groups of rollers 38, the fixed seat 2 is fixedly installed inside the fixed shell 1, one side of the fixed disk 31 is fixedly connected to one side of the fixed seat 2, one end of the screw 32 is rotatably connected to the interior of the fixed disk 31, the other ends of the six groups of connecting rods 36 are rotatably connected to the interiors of the three groups of connecting shells 37 respectively, one end of the three groups of connecting rods 36 is rotatably connected to the interior of the fixed disk 31, and one end of the other three groups of connecting rods 36 is rotatably connected to the interior of the connecting sleeve 34.

[0024] The following is a detailed description of the specific settings and functions of this embodiment. When installing the flange, there is a discrepancy between the inner diameter of the flange and the inner diameter of the pipe. First, place the pipe and the flange together, adjust the support mechanism 4 so that the support plate 45 fits tightly against the inner wall of the pipe, and then the staff holds the position of the connecting plate 35 by hand or with the help of a tool, and then manually rotates the connecting ring 33 and the screw 32, and then the connecting sleeve 34 moves on the outer wall of the screw 32, and the distance between the fixed plate 31 and the connecting sleeve 34 gradually increases. The six groups of connecting rods 36 deflect, and the three groups of connecting shells 37 gradually move from the center to the outside until the six groups of rollers 38 closely contact the inner wall of the flange, thereby fixing the position of the flange, and coaxially fitting the end face of the flange with the end face of the pipe and then welding them. By setting the fixing mechanism 3, the flanges and pipes with different diameters are positioned so that the flanges and pipes are coaxially installed, which can ensure that the flanges and pipes are on the same axis, reduce the movement and friction of the connection, increase the stability of the connection, improve the sealing of the connection, reduce the looseness and wear of the connection, and reduce the risk of leakage.

[0025] Embodiment 2

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a support mechanism 4 is provided on one side of the fixed shell 1, and the support mechanism 4 includes a servo motor 41 and three groups of gears 42. The servo motor 41 is fixedly installed inside the fixed shell 1, and the output end of the servo motor 41 is transmission-connected to one side of a group of gears 42. One end of the three groups of gears 42 are all rotationally connected to the inside of the fixed shell 1. The outer wall of the gear 42 is engaged with a limit plate 43, and the limit plate 43 is movably arranged inside the fixed shell 1. Three groups of limit seats 44 are clamped on one side of the limit plate 43, and one side of the three groups of limit seats 44 are fixedly installed with a support plate 45, and one side of the three groups of limit seats 44 are all slidingly connected to the inside of the fixed shell 1.

[0027] The effect achieved by the entire embodiment is that, first, one end of the flange is fitted with one end of the pipe, the device is placed inside the pipe, and the servo motor 41 is started to drive a group of gears 42 to rotate, thereby driving the limit plate 43 to rotate. Since one side of the limit plate 43 is a toothed tooth and the other side is a limiting wire groove, the other two groups of gears 42 are driven to rotate synchronously. The wire groove on the other side of the limit plate 43 is spiral. Therefore, during the rotation of the limit plate 43, the three groups of limit seats 44 will be driven to move, and the limit seats 44 will drive the three groups of support plates 45 to move until one side of the three groups of support plates 45 is close to the inside of the pipe. At this time, the screw 32 is located at the central axis position of the pipe and the flange. By setting the support mechanism 4, the inside of the pipe can be internally supported and fixed, thereby limiting the position of the screw 32, and cooperating with the adjustment and fixing mechanism 3 to limit the position of the flange, the coaxial installation of the pipe and the flange is realized, the movement and friction at the connection are reduced, the stability of the connection is increased, and the sealing of the connection is improved.

[0028] The use method and working principle of this device: when installing the flange, if the inner diameter of the flange is inconsistent with the inner diameter of the pipe, first fit one end of the flange with one end of the pipe, place the device inside the pipe, start the servo motor 41, drive a set of gears 42 to rotate, and then drive the limit plate 43 to rotate. Since one side of the limit plate 43 is a toothed tooth and the other side is a limit groove, the other two sets of gears 42 are driven to rotate synchronously. The groove on the other side of the limit plate 43 is spiral. Therefore, during the rotation of the limit plate 43, the three sets of limit seats 44 are driven to move, and the limit seats 44 drive the three sets of support plates 45 to move. The connecting ring 33 and the screw 32 are manually rotated, and the connecting sleeve 34 moves on the outer wall of the screw 32. The distance between the fixed plate 31 and the connecting sleeve 34 gradually increases, and the six connecting rods 36 are deflected. The three connecting shells 37 gradually move from the center to the outside until the six rollers 38 are in close contact with the inner wall of the flange, thereby fixing the position of the flange, and welding the end face of the flange to the end face of the pipeline coaxially.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
