[0033] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0034] According to one aspect of this application, a fixing device 10 for welding flanged pipes is provided. See also Figure 1 The fixing device 10 may include a base plate 20 and at least three fixing mechanisms 30.
[0035] According to the example embodiment, at least three fixing mechanisms 30 can be vertically fixed to the upper surface of the substrate 20, and the at least three fixing mechanisms 30 are arranged radially around the center point of the substrate 20.
[0036] The center point of the substrate 20 can be the intersection of the diagonals of the substrate 20, or it can be the center of a circle of the substrate 20, etc. The first end of the fixing mechanism 30 is close to the center point, and the second end of the fixing mechanism 30 extends radially with the center point as the center.
[0037] Adjacent fixing mechanisms 30 have the same preset angle, which can be determined based on the number of fixing mechanisms 30. The fixing mechanisms 30 can be evenly distributed. The number of fixing mechanisms 30 can be determined based on the diameter of the flange 40. For example, if the flange 40 has a small diameter (e.g., 10 cm), six fixing mechanisms 30 can be installed. See also Figure 1 For flanges with a larger diameter (e.g., 20 cm), up to six fixing mechanisms (30) can be installed. See also... Figure 2 When the flange diameter is large (e.g., 30 cm), nine fixing mechanisms can be installed.
[0038] See Figure 3 and Figure 4 The fixing mechanism 30 includes a corner cylinder 31, a support block 32, and a pressure block 33. The corner cylinder 31 includes a fixing part 311 and a rotating part 312. One end of the fixing part 311 is connected to the upper surface of the substrate 20. The first end of the rotating part 312 is rotatably connected to the other end of the fixing part 311 in a horizontal direction with the first end of the rotating part 312 as the axis, and the first end of the rotating part 312 is slidably connected to the other end of the fixing part 311 in a direction perpendicular to the upper surface of the substrate 20.
[0039] For example, by operating the control valve (not shown in the figure), the connection between the intake gas pipeline or the exhaust gas pipeline and the rotary cylinder 31 can be controlled. When the intake gas pipeline is in operation, the rotating part 312 rotates horizontally about its first end as the axis, while simultaneously sliding downwards in a direction perpendicular to the upper surface of the substrate 20.
[0040] See Figure 3 and Figure 4 The lower surface of the support block 32 is vertically disposed on the upper surface of the base plate 20, and the support block 32 is disposed on the side of the fixing part 311 near the center point. The upper surface of the support block 32 supports the flange 40 to be welded. One end of the pressure block 33 is connected to the other end of the rotating part 312, and the other end of the pressure block 33 is used to contact the flange 40.
[0041] With the flange 40 placed on the upper surface of the support block 32, the rotating part 312 rotates and moves downward in a direction perpendicular to the upper surface of the substrate 20, driving the pressure block 33 to move until the pressure block 33 comes into contact with the flange 40.
[0042] For example, see Figure 5 With flange 40 placed on the upper surface of support block 32, by operating the control valve (not shown in the figure), the intake gas pipeline can be connected to the angle cylinder 31. The rotating part 312 rotates horizontally around its first end, while simultaneously sliding downwards along the direction perpendicular to the upper surface of the base plate 20. The rotating part 312 can drive the pressure block 33 to move, gradually approaching flange 40, until the lower surface of the pressure block 33 contacts the upper surface of flange 40. Figure 6 As shown. The pressure block 33 can apply downward pressure to the flange 40 along the upper surface perpendicular to the base plate 20.
[0043] The operator can control all the corner cylinders 31 simultaneously through the intake gas pipeline or the exhaust gas pipeline, or control each corner cylinder 31 individually.
[0044] After the flange 40 is fixed to the pipe 50, it can be welded manually or by a robot.
[0045] Through the above embodiments, the technical solution of this application can apply downward pressure perpendicular to the upper surface of the base plate to the flange through the fixing mechanism, so that the gap between the flange and the pipe can be uniform, and horizontal deformation of the flange can be avoided, thereby improving the welding quality. Multiple fixing mechanisms can also make the flange bear force evenly.
[0046] Optionally, the pressure block 33 and the rotating part 312 are detachably connected, and the pressure block 33 can be replaced according to the shape of the flange to accommodate flanges of different shapes.
[0047] Optionally, the support block 32 is detachably connected to the base plate 20, and the support block 32 can be replaced according to the shape of the flange to accommodate flanges of different shapes.
[0048] Optionally, see Figure 3 The upper surface of the support block 32 is provided with a U-shaped groove. The sidewalls and bottom surface of the U-shaped groove can be arc-shaped to correspond to the flange, so as to fit the flange snugly. The number and curvature of the U-shaped groove can be determined according to the shape of the flange.
[0049] Optionally, see Figure 3 and Figure 4 The fixing mechanism 30 also includes a sliding part 34. The sliding part 34 may include a guide rail 341, a slider 342, and a connecting block 343.
[0050] According to the example embodiment, the guide rail 341 is radially fixed on the upper surface of the substrate 20 with the center point as the center. The first end of the guide rail 341 is close to the center point, and the second end of the guide rail 341 extends radially with the center point as the center.
[0051] Slider 342 is disposed on both sides of guide rail 341 and is slidably connected to guide rail 341. For example, slider 342 can slide along the direction of guide rail 341 through mutually cooperating grooves and protrusions.
[0052] The lower surface of the connecting block 343 is fixedly connected to the upper surface of the slider 342, and the upper surface of the connecting block 343 is fixedly connected to the lower surface of the fixing part 311.
[0053] When the slider 342 slides, it can drive the connecting block 343 and the fixing part 311 to slide, thereby driving the pressure block 33 and the support block 32 to move, so that the fixing device 10 can adapt to flanges of different diameters.
[0054] Optionally, the support block 32 is detachably connected to the guide rail 341, and the support block 32 can be replaced according to the shape of the flange to accommodate flanges of different shapes.
[0055] Optionally, see Figure 3 and Figure 4 The sliding part 34 also includes a guide rail brake 344. The guide rail brake 344 is detachably connected to the second end of the guide rail 341 and fixedly connected to the connecting block 343. The operator can control the sliding of the slider 342 on the guide rail 341 through the guide rail brake 344. When the slider 342 slides to the target position, the operator can fix the slider 342 in the target position through the guide rail brake 344.
[0056] The operator can manually control the sliding of each slider 342, or control the sliding of all sliders 342 simultaneously through electrical control.
[0057] Optionally, the substrate 20 and the connecting block 343 can be made of 6061 aluminum alloy, and the pressure block 33 and the support block 32 can both be made of 45# aluminum alloy.
[0058] According to another aspect of this application, this application provides a welding apparatus, which includes the fixing device 10 as described above.
[0059] Finally, it should be noted that the above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions of the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
