Technical Field

[0001] The utility model relates to the technical field of metal welding, in particular to a metal processing welding auxiliary device. Background Art

[0002] Pipe butt welding is a commonly used metal connection technology, widely used in industry and construction. Pipe butt welding is a process of heating the interface of two pipes to a molten state, then fusing them together, and forming a strong connection after cooling. During the welding process, it is necessary to use appropriate welding materials to fill the interface to improve the firmness and sealing of the connection.

[0003] The existing patent number CN213351398U proposes a welding auxiliary device for metal pipe processing, including a workbench, a support leg is fixedly installed at the bottom of the workbench, and fine-tuning brackets are fixedly installed at both ends of the upper surface of the workbench, and an adjustment baffle is slidably connected in the fine-tuning bracket. Support sliders are slidably connected on both sides of the upper surface of the workbench. However, when the above-mentioned welding auxiliary device for metal pipe processing is in use, the two sections of metal pipes to be welded are respectively fixed by two groups of clamping mechanisms. If the tightening force is different when controlling the two groups of clamping mechanisms to clamp the pipes, it is very easy to cause the welding positions of the two sections of metal pipes to be unable to be aligned, which causes certain difficulties in the welding work. Therefore, a metal processing welding auxiliary device is proposed. Utility Model Content

[0022] like Figure 1 to Figure 2As shown, a metal processing welding auxiliary device comprises a workbench 1, a groove 2 is provided on the top of the workbench 1, a U-shaped frame 3 is fixedly installed on the top of the workbench 1, cylinders 4 are fixedly installed on the two symmetrical side walls inside the U-shaped frame 3, a U-shaped rod 5 is fixedly installed on the output end of each cylinder 4, a clamping plate 6 is fixedly installed on both ends of each U-shaped rod 5, a cylinder 2 7 is fixedly installed on the inner top surface of the U-shaped frame 3, a U-shaped rod 2 8 is fixedly installed on the output end of the cylinder 2 7, and a clamping plate 2 9 is fixedly installed on both ends of the U-shaped rod 2 8. It should be noted that if two sections of metal pipes need to be welded, the two sections of metal pipes are first placed on the upper surface of the workbench 1, and then the two sections of metal pipes are fixedly installed on the upper surface of the workbench 1. At the same time, the two sections of metal pipes are respectively located between each two adjacent clamping plates 6, and then the welding ends of the two sections of metal pipes are aligned, and the two cylinders 4 and 7 are started at the same time, each cylinder 4 drives the U-shaped rod 5 connected to it to move, and each U-shaped rod 5 drives the two clamping plates 6 connected to it to move, so that each clamping plate 6 approaches the metal pipe to complete the clamping, and at the same time, the cylinder 27 drives the U-shaped rod 28 to move downward, and the U-shaped rod 28 drives the two clamping plates 29 to move downward to complete the pressing of the metal pipe, thereby solving the problem of different tightening forces of the two sections of metal pipes when clamping the auxiliary device for metal pipe welding in the existing metal processing welding auxiliary device.

[0023] like Figure 1 , Figure 2 As shown, two side walls of the workbench 1 are provided with two slide grooves 10, each of which is movably installed with a slide rod 11 inside, and a supporting leg 12 is fixedly installed at the bottom of each slide rod 11, a connecting rod 13 is fixedly installed between each two adjacent slide rods 11, and an electric telescopic rod 14 is fixedly installed on the top of each connecting rod 13, and a cylinder three 15 is fixedly installed on the output end side wall of each electric telescopic rod 14, and an extrusion cone 16 is fixedly installed on the output end of each cylinder three 15. It should be noted that the staff can pull the two connecting rods 13 closer to or farther away from the workbench 1 according to the length of the metal pipe to be welded, and each connecting rod 13 drives the two slide rods 11 connected to it to slide back and forth in the corresponding slide groove 10 respectively. After the two connecting rods 13 are moved to the appropriate position, each electric telescopic rod 14 is lifted and lowered to the appropriate position, and each cylinder three 15 drives the adjacent extrusion cones 16 to move closer to the two ends of the two metal pipes that are far away from each other, thereby squeezing the two metals close together for easy welding.

[0024] like Figure 1 , Figure 2 As shown, the extrusion cone 16 has a conical structure, and the tip of each extrusion cone 16 is far away from the output end of the adjacent cylinder three 15. It should be noted that when the extrusion cone 16 is extruding the metal pipe, the extrusion cone 16 can be inserted into the metal pipe. Since the extrusion cone 16 has a conical structure, it can be used for metal pipes of different diameters.

[0025] like Figure 1 , Figure 2 As shown, a threaded hole 17 is opened on the top of the workbench 1 corresponding to the position of each slide slot 10, and a bolt 18 is threadedly connected to the inside of each threaded hole 17. It should be noted that when the two connecting rods 13 are moved to the appropriate position, each bolt 18 is rotated respectively to move, thereby fixing the position of the four slide slots 10.

[0026] like Figure 2 , Figure 3 As shown, two arc grooves 19 are provided on the top of the workbench 1, and a plurality of arc plates 20 of equal size are arranged inside each arc groove 19. It should be noted that when two sections of metal pipes are respectively located between each two adjacent clamping plates 6, the two sections of metal pipes can be placed inside the two arc grooves 19 respectively, and at the same time, several arc plates 20 can be stacked inside each arc groove 19 according to the diameter of the metal pipe. Finally, the two sections of metal pipes are respectively placed inside the two uppermost arc plates 20, so as to avoid excessive position errors when the metal pipes are placed.

[0027] like Figure 2 , Figure 3 As shown, a limit rod 21 is fixedly installed at the bottom of each arc plate 20, and a limit groove 22 compatible with the adjacent limit rod 21 is opened on the inner arc surface of each arc groove 19, and a limit groove 22 is opened at the position of the inner arc surface of each arc plate 20 corresponding to the upper limit rod 21, and each limit rod 21 is movably installed inside the adjacent limit groove 22. It should be noted that the staff only needs to pull the corresponding arc plate 20 so that the arc plate 20 drives the limit rod 21 connected to it to slide out from the corresponding limit groove 22 to remove it, and the position of the corresponding arc plate 20 can be limited by the cooperation of the limit rod 21 and the limit groove 22 so that it will not move easily.

[0028] In summary:

[0029] If it is necessary to weld two sections of metal pipes, first place the two sections of metal pipes on the upper surface of the workbench 1, and make the two sections of metal pipes respectively located between each two adjacent clamping plates 6, then align the welding ends of the two sections of metal pipes, and start the two cylinders 4 and cylinders 2 7 at the same time, each cylinder 4 drives the U-shaped rod 5 connected to it to move, and each U-shaped rod 5 drives the two clamping plates 6 connected to it to move, so that each clamping plate 6 approaches the metal pipe to complete the clamping, and at the same time, the cylinder 2 7 drives the U-shaped rod 2 8 to move downward, and the U-shaped rod 2 8 drives the two clamping plates 2 9 to move downward to complete the pressing of the metal pipe, thereby solving the problem of different tightening forces of the two sections of metal pipes when clamping the auxiliary device for metal pipe welding in the existing metal processing welding auxiliary device.
