Technical Field
[0001] This utility model relates to the field of electric welding auxiliary equipment technology, and in particular to a flange welding adjustment bracket. Background Technology
[0002] A cooler is a type of heat exchange equipment used to cool fluids. It typically uses water or air as a coolant to remove heat. They can be mainly classified into shell-and-tube coolers, plate coolers, and air-cooled coolers. Coolers are widely used heat exchange devices in industries such as metallurgy, chemical engineering, energy, transportation, light industry, and food processing.
[0003] In the actual production process of the cooler, most of the pipes and flanges of the cooler are welded by hand. First, the flange is placed flat on the workbench, and then the connecting pipe is inserted into the flange. The welder holds the pipe with one hand and holds the welding gun with the other hand to weld the pipe and flange together. Because it is difficult to weld various thick-walled and small-diameter pipes and flanges, it is impossible to be precise, stable and prevent scalding by hand. Therefore, it is necessary to adjust a stable and reasonably angled plane as the flange support base to create good welding conditions.
[0004] Therefore, those skilled in the art have provided a flange welding adjustment bracket to solve the problems mentioned in the background art. Utility Model Content

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0028] See Figure 1-4 As shown;
[0029] The flange welding adjustment bracket described in this embodiment of the utility model includes:
[0030] The base 1 has an upper tray 2 on top of it. The flange is placed on the top surface of the upper tray 2. When the flange slips off due to excessive welding angle, it can be spot welded to the tray 2.
[0031] Three steel cylinders 3 are evenly distributed between the base 1 and the upper tray 2. Each steel cylinder 3 is equipped with a telescopic rod 4 inside. The bottom end of the steel cylinder 3 is rotatably connected to the top edge of the base 1, and the top end of the telescopic rod 4 is rotatably connected to the bottom edge of the upper tray 2.
[0032] In practical use, this application uses three telescopic rods 4 as fulcrums to determine the plane on which the upper pallet 2 is located. It uses three sets of steel cylinders 3 and freely telescopic and adjustable telescopic rods 4 to adjust the plane on which the upper pallet 2 is located so that the flange on it can adapt to welding at various angles.
[0033] The bracket in this application consists of two layers, upper and lower. When in use, the lower base 1 is placed on a flat ground, and the flange to be welded is placed on the top surface of the upper tray 2. By adjusting the extension length of the three telescopic rods 4, the upper tray 2 can be adjusted at various angles and heights, thereby adjusting the relative position of the flange and the copper pipe and creating good welding conditions.
[0034] Furthermore, the bottom end of the steel cylinder 3 has a first nut 5, a first hinge 6 is inserted inside the first nut 5, and the part of the first hinge 6 located outside the first nut 5 passes through a second nut 7 respectively. The two second nuts 7 are welded to the edge of the top surface of the base 1.
[0035] The first hinge pin 6 is rotatably connected to both the first nut 5 and the second nut 7, so that the steel cylinder 3 can swing along the axis of the first hinge pin 6.
[0036] Furthermore, the top of the telescopic rod 4 has a third nut 8, a second hinge 9 is inserted inside the third nut 8, and the part of the second hinge 9 located outside the third nut 8 passes through a fourth nut 10 respectively. The two fourth nuts 10 are welded to the edge of the bottom surface of the upper tray 2.
[0037] The second hinge pin 9 is rotatably connected to both the third nut 8 and the fourth nut 10, so that the telescopic rod 4 can swing along the axis of the second hinge pin 9.
[0038] When the telescopic rod 4 extends, it swings inward along the second hinge axis 9, and the angle between the telescopic rod 4 and the upper tray 2 gradually increases. The steel cylinder 3 swings outward along the first hinge axis 6, and the angle between the steel cylinder 3 and the base 1 gradually increases. When the telescopic rod 4 retracts, it swings outward along the second hinge axis 9, and the angle between the telescopic rod 4 and the upper tray 2 gradually decreases. The steel cylinder 3 swings inward along the first hinge axis 6, and the angle between the steel cylinder 3 and the base 1 gradually decreases.
[0039] See Figure 3 , 5 As shown in -6;
[0040] A set screw 11 is provided on the outer side of the top of the steel cylinder 3. The bottom end of the set screw 11 can extend into the steel cylinder 3 and abut against the outer wall of the telescopic rod 4.
[0041] When the telescopic rod 4 extends to the preset length, tighten the set screw 11 so that the bottom end of the set screw 11 is tightly against the telescopic rod 4, so that the telescopic rod 4 maintains this length, so that the flange on the upper tray 2 can be welded to the angle of the copper pipe.
[0042] A positioning cylinder 12 is provided at the top of the steel cylinder 3, the bottom of the set screw 11 is threaded to the inner wall of the positioning cylinder 12, and a fixing plate 13 is welded between the outer wall of the positioning cylinder 12 and the outer wall of the steel cylinder 3.
[0043] The positioning cylinder 12 enables the set screw 11 to be positioned on the top of the steel cylinder 3 and prevents the set screw 11 from falling off. The positioning cylinder 12 is fixed to the top of the steel cylinder 3 by the fixing plates 13 on the upper and lower sides of the positioning cylinder 12, so as to facilitate the tightening of the set screw 11.
[0044] Furthermore, the set screw 11 includes a crossbar 14 and a threaded rod 15. The top end of the threaded rod 15 is welded to the middle of the bottom surface of the crossbar 14, and the threaded rod 15 extends into the positioning cylinder 12 and is threadedly connected to it.
[0045] The crossbar 14 is designed to allow the user to rotate the threaded rod 15. The threaded connection between the threaded rod 15 and the positioning cylinder 12 allows the threaded rod 15 to be positioned on the top of the steel cylinder 3. It also allows the threaded rod 15 to smoothly enter the steel cylinder 3 and to press the telescopic rod 4 inside the steel cylinder 3 tightly, preventing the telescopic rod 4 from shifting.
[0046] Furthermore, a through hole 16 is provided in the center of the top surface of the upper tray 2 to facilitate fine adjustment of the relative position of the flange and the pipeline during welding.
[0047] During operation, the flange is placed on the upper tray 2, and the bracket for placing the flange is placed below the copper pipe to be welded. The height of the three telescopic rods 4 is adjusted so that the flange adapts to the angle of the copper pipe and contacts the part to be welded to the copper pipe. The set screws 11 are tightened to fix the telescopic rods 4 and prevent displacement that would affect the welding effect. This application does not require manual support for the flange and can make contact between the flange and the copper pipe welding part to ensure the welding effect. It solves the welding problems of no fixed plane, difficulty in stabilizing by hand support, and difficulty in fine adjustment of angle when welding copper pipe and flange of cooler.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
