Description

Technical Field

[0001] The present application relates to the technical field of mechanical automated welding, and in particular to an automated pipe welding device. Background Art

[0002] In modern industrial production, pipe welding is a common operation link. Especially in the pipeline processing industry, efficient and high-quality welding of pipe fittings is of great significance to improving product quality.

[0003] At present, traditional welding operations mostly rely on manual operations. Welders need to manually place the cylindrical workpiece to be welded into the fixed groove for preliminary positioning, put the annular workpiece on the cylindrical workpiece, and then step on the welding machine foot switch to start the welding equipment. The welder holds the cylindrical workpiece and rotates it manually to complete a circle of welding the annular workpiece and the cylindrical workpiece. This requires manual participation in many operation processes and a lot of manual intervention. Not only is the efficiency low, but also due to the influence of human factors, the welding quality is difficult to guarantee, resulting in inconsistent surface quality of welded parts, a high secondary repair rate, increased labor intensity of welders, low work efficiency and high cost.

[0010] The moving mechanism is connected to the top of the workbench and is used to drive the clamping mechanism to move horizontally. The moving mechanism is connected to a rotating drive member, and the output end of the rotating drive member is connected to the rotating shaft.

[0011] By adopting the above technical solution, when it is necessary to weld the workpiece, the lifting mechanism controls the height of the welding machine so that the welding head of the welding machine can be accurately aligned with the welding position; the clamping mechanism firmly clamps the workpiece, and through the linkage of the turntable and the rotating shaft, the workpiece rotates smoothly during the welding process, reducing the instability and possibility of human error in traditional manual operation. At the same time, the moving mechanism can accurately adjust the position of the clamping mechanism in the horizontal direction, further ensuring the stability and consistency of the welding process, thereby reducing the welding defect rate, reducing the number of rework times, and effectively improving production efficiency and product quality.

[0047] In order to further realize automation, a control box 9 is fixedly connected to the top wall of the workbench 2. A controller is installed in the control box 9. The controller is used to control the clamping mechanism 3, the rotating drive member 71 and the lifting drive member 61.

[0048] Specifically, refer to Figure 2 and Figure 3 The mounting assembly includes a mounting piece 82 and a set piece 83. There are two mounting pieces 82, and the two mounting pieces 82 are hinged. One end of the two mounting pieces 82 is hinged to form a clamping opening for clamping the welding machine 1. The mounting piece 82 is clamped on one end of the welding machine 1 and is convex. The set piece 83 is fitted on the two mounting pieces 82, so that one end of the mounting piece 82 with the clamping opening is against the set piece 83, and the position of the set piece 83 on the mounting piece 82 is limited. The set piece 83 is provided with a slot that matches the two mounting pieces 82 for insertion. The fitting part of the mounting piece 82 and the set piece 83 is in the shape of a square column, thereby reducing the possibility of the mounting piece 82 rotating in the set piece 83. To improve the anti-rotation ability, the two mounting parts 82 located in the set 83 fit together, the outer wall of the set 83 is in a ring shape, and the lifting seat 63 is provided with an insertion opening, which is circular, and the set 83 is inserted into the insertion opening.

[0049] When the welding machine 1 needs to be replaced, the fixing rod 8 is taken out from the fixing mouth, the limiting ring 85 is twisted, and the limiting ring 85 is disassembled from the set 83. The operator holds the set 83 close to one end of the welding machine 1, thereby pulling the set 83 off from the lifting seat 63, and then pulls the mounting part 82 out of the set 83, so that the two mounting parts 82 are in a free state, and the welding machine 1 is disassembled from the mounting part 82, thereby realizing the possibility of replacing the welding machine 1, improving convenience, and facilitating the replacement of the set 83 and the mounting part 82, reducing the possibility of welding shaking due to severe wear of the set 83 or the mounting part 82, thereby improving welding quality, reducing the possibility of rework, and improving work efficiency.

[0050] The lifting seat 63 is fixedly connected to the side away from the welding machine 1 with an adjusting member 86, which is in an arc shape. The adjusting member 86 is provided with a sliding groove 861, which is in an arc shape. One end of the sliding groove 861 is through-shaped, and the end of the fixed rod 8 away from the mounting member 82 slides with the adjusting member 86 through the sliding groove 861. The fixed rod 8 is inserted into the sliding groove 861. The fixed rod 8 is in a square column shape, and the raised end of the fixed rod 8 is against the end of the mounting member 82 away from the welding machine 1. When the angle of the welding machine 1 is adjusted, the rotating The fixing rod 8 rotates to drive the mounting member 82 to rotate, so that the set member 83 rotates on the lifting seat 63, and then the welding angle of the welding machine 1 is adjusted. In order to stably fix the welding angle of the welding machine 1, the locking member 81 is inserted into the sliding groove 861, and the locking member 81 is threadedly matched with the fixing rod 8. When the fixing rod 8 is fixed, the locking member 81 is against the groove wall of the sliding groove 861. When the fixing rod 8 is removed, the end of the fixing rod 8 away from the mounting member 82 is slid out from the end through the sliding groove 861.

[0051] In order to facilitate locking of the fixing rod 8 , one end of the locking member 81 away from the fixing rod 8 is fixedly connected to a twisting member 87 , which is T-shaped.

[0052] The implementation principle of an automated pipe welding device according to an embodiment of the present application is as follows: a cylindrical workpiece to be welded is placed in a clamping mechanism 3, the workpiece is firmly clamped by adjusting the opening and closing degree of the clamping mechanism 3, the lifting drive 61 drives the lifting screw 62 to rotate, and the lifting screw 62 drives the lifting seat 63 to move up and down, thereby adjusting the height of the welding head of the welding machine 1 so that the welding head of the welding machine 1 is aligned with the welding position of the cylindrical workpiece, the adjusting hand wheel 42 drives the adjusting screw 43 to rotate, and the adjusting screw 43 drives the moving seat 44 to move horizontally along the base 41, thereby adjusting the clamping mechanism The rotating drive member 71 is turned on and the turntable 7 is rotated via the rotating shaft, thereby rotating the cylindrical workpiece and the annular workpiece in the clamping mechanism 3.
