[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0021] Referring to Figures 1-4 , a special-shaped flange processing tooling includes a base 1. A plurality of columns 2 are arranged on the base 1. The tops of the plurality of columns 2 are connected to the same top plate 3. A first adjustment mechanism 4 and a second adjustment mechanism 5 are respectively arranged on the top and bottom of the top plate 3. A plurality of first moving columns 6 are slidably connected to the top of the top plate 3. The first moving columns 6 are evenly arranged in a circular shape with the center of the top plate 3 as the center of the circle. A plurality of second moving columns 7 are slidably connected to the top of the top plate 3. The second moving columns 7 are evenly arranged in a circular shape with the center of the top plate 3 as the center of the circle and are located outside the first moving columns 6. A plurality of guide grooves 8 are formed in the top plate 3. The plurality of guide grooves 8 are evenly arranged in a circular shape along the radial direction of the top plate 3. A first guide shaft 9 and a second guide shaft 10 are respectively slidably connected in each guide groove 8. The first guide shaft 9 is connected to the bottom end of the first moving column 6. The second guide shaft 10 is connected to the bottom end of the second moving column 7. Each first moving column 6 is rotatably connected to the first adjustment mechanism 4 through a first connecting rod 11. Each second guide shaft 10 is rotatably connected to the second adjustment mechanism 5 through a second connecting rod 12.
[0022] By adding the first adjusting mechanism 4 and the first connecting rod 11, and guiding through the first guiding shaft 9 and the guiding groove 8, several first moving columns 6 achieve synchronous circular radial movement, thereby providing inner circle limiting support for the assembly of the special-shaped flange. By adding the second adjusting mechanism 5 and the second connecting rod 12, and guiding through the second guiding shaft 10 and the guiding groove 8, several second moving columns 7 achieve synchronous circular radial movement, thereby providing outer circle limiting support for the assembly of the special-shaped flange, and further ensuring the concentricity of the inner circle and the outer circle after the assembly of the special-shaped flange. The operation is simple and convenient, and at the same time, the welding precision is improved. Through the cooperation between the first adjusting mechanism 4 and the first moving column 6, the relative adjustment of the inner circle specification of the special-shaped flange is realized. Through the cooperation between the second adjusting mechanism 5 and the second moving column 7, the relative adjustment of the outer circle specification of the special-shaped flange is realized, making the tooling adaptable to the welding processing of special-shaped flanges of different sizes, and effectively improving the adaptability of the tooling.
[0023] Specifically, in this embodiment, the first adjusting mechanism 4 and the second adjusting mechanism 5 are the same, and both are composed of a fixed pipe 13, a moving pipe 14, a screw 15 and a handwheel 16. The fixed pipe 13 is connected to the top plate 3. The moving pipe 14 is sleeved on the fixed pipe 13. The screw 15 is rotatably connected in the moving pipe 14 and is threadedly connected in the fixed pipe 13. The handwheel 16 is connected to the screw 15 and is located outside the moving pipe 14. The first connecting rod 11 and the second connecting rod 12 are respectively rotatably connected to the outer walls of the moving pipes 14 at the first adjusting mechanism 4 and the second adjusting mechanism 5.
[0024] Drive the screw 15 to rotate by using the handwheel 16. The screw 15 screws into the fixed pipe 13. The pressure of the handwheel 16 disc acts on the end of the moving pipe 14, causing the moving pipe 14 to move towards the fixed pipe 13, realizing the change of the position of the connection part between the connecting rod and the fixed pipe 13, and thus realizing the position adjustment of the moving column.
[0025] Specifically, in this embodiment, a threaded hole 17 is opened in the fixed pipe 13. The screw 15 is threadedly adapted in the threaded hole 17, realizing the change of the extending length of the screw 15 in the fixed pipe 13 and maintaining the stability of the screw 15 in the fixed pipe 13 after screwing.
[0026] Specifically, in this embodiment, one end of the moving pipe 14 is closed, and a support shaft 18 is rotatably connected inside. The support shaft 18 is connected between the screw 15 and the handwheel 16, restricting the axial movement of the screw 15 in the moving pipe 14, and facilitating the smooth movement of the moving pipe 14 away from the fixed pipe 13 when the screw 15 is screwed in the reverse direction.
[0027] Specifically, in this embodiment, step grooves 19 with the same depth are formed at the tops of the first moving column 6 and the second moving column 7, providing bottom support for several arc-shaped petals of the special-shaped flange and ensuring sufficient welding space is reserved between the special-shaped flange and the top plate 3.
[0028] Specifically, in this embodiment, a third connecting rod 20 is rotatably connected to the first moving column 6, and the third connecting rod 20 is rotatably connected to the outer wall of the moving pipe 14 at the first adjusting mechanism 4. The third connecting rod 20 is parallel to the first connecting rod 11, further improving the stability of the connection between the first adjusting mechanism 4 and the first moving column 6.
[0029] Specifically, in this embodiment, a limiting groove 21 is formed on the inner wall of the middle part of the guiding groove 8, and limiting shafts 22 are arranged on the outer walls of the middle parts of the first guiding shaft 9 and the second guiding shaft 10. The limiting shafts 22 are slidably connected in the limiting groove 21, ensuring that the first guiding shaft 9 and the second guiding shaft 10 can slide smoothly in the guiding groove 8 while preventing the first guiding shaft 9 and the second guiding shaft 10 from separating from the guiding groove 8.
[0030] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
