Description

Technical Field

[0001] The utility model relates to the field of automatic welding equipment, in particular to a tube-to-tube intersecting line TIG automatic welding system. Background Art

[0002] Tube-to-tube intersecting line TIG welding is a special and precise welding technology, mainly used for welding when two round tubes intersect, especially widely used in fields such as petroleum, chemical industry, shipbuilding and construction. This technology not only requires high-precision operation, but also requires precise control of various parameters during the welding process to ensure welding quality and efficiency.

[0003] Welding principle: Tube-to-tube intersecting line TIG welding heats through an electric arc or flame to melt the contact surfaces of the two round tubes, and a firm connection is formed in the molten state. During welding, through filler materials or self-fusion methods, the metals at the joint are fused to form a continuous and uniform weld seam.

[0004] Since tube-to-tube intersecting line welding requires high precision and mainly relies on manual cooperation with positioning equipment for welding, it greatly limits the welding efficiency and the automation level is relatively low. Therefore, how to improve the welding efficiency on the premise of ensuring precision has become an urgent problem for those skilled in the art. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies existing in the prior art, and provide a tube-to-tube intersecting line TIG automatic welding system, which can effectively improve the welding efficiency of the tube-to-tube intersecting line on the premise of ensuring precision, and has great market promotion value.

[0006] The utility model is realized through the following technical solutions:

[0007] A tube-to-tube intersecting line TIG automatic welding system includes a lower clamping mechanism, an upper clamping mechanism, a welding torch adjustment mechanism and a welding torch. The lower clamping mechanism clamps and locks the horizontal pipe section, and the upper clamping mechanism clamps and locks the vertical pipe section. The intersecting line of the horizontal pipe section and the vertical pipe section intersects. The welding torch adjustment mechanism includes a lifting component, an angle adjustment component and an arc voltage tracking slide plate. The lifting component is vertically slidably connected to the operation table through a support arm. The lifting component drives the angle adjustment component, the arc voltage tracking slide plate and the welding torch to slide up and down. The angle adjustment component drives the arc voltage tracking slide plate and the welding torch to rotate by a set angle. The free end of the arc voltage tracking slide plate is connected to the welding torch.

[0008] It can be seen that in the above technical solution, the staff adjusts the lower clamping mechanism and the upper clamping mechanism so that the lower clamping mechanism clamps and locks the horizontal pipe section, and the upper clamping mechanism clamps and locks the vertical pipe section. At this time, the intersection line of the horizontal pipe section and the vertical pipe section intersects at the set position. Then, the lifting assembly drives the angle adjustment assembly, the arc voltage tracking slide plate and the welding torch to slide up and down. The angle adjustment assembly drives the arc voltage tracking slide plate and the welding torch to rotate by a set angle. At this time, the welding position of the welding torch is facing the joint of the horizontal pipe section and the vertical pipe section. As the lower clamping mechanism drives the horizontal pipe section to rotate smoothly, the lifting assembly synchronously fine-tunes the up and down sliding, so as to effectively improve the welding efficiency of the pipe-to-pipe intersection line on the premise of ensuring accuracy, and has great market promotion value.

[0009] According to the above technical solution, preferably, the lower clamping mechanism includes a rotating assembly, an X-direction adjustment assembly and two symmetrically arranged Y-direction clamping assemblies. The rotating assembly includes a first motor and a turntable. The first motor drives the turntable to rotate, and the turntable is rotatably connected to the operation table. The X-direction adjustment assembly includes a first fixed seat and a first slide table. The first fixed seat is coaxially and fixedly connected to the turntable. The first slide table is slidably connected to the first fixed seat through a first lead screw unit. The Y-direction clamping assembly includes a second fixed seat and a second slide table. The second fixed seat is fixedly connected to the first slide table. The second slide table is slidably connected to the second fixed seat through a first lead screw unit. The moving directions of the first slide table and the second slide table are perpendicular to each other. The second slide table is provided with chucks for clamping both ends of the horizontal pipe section.

[0010] It can be seen that in the above technical solution, the X-direction adjustment assembly drives the Y-direction clamping assembly and the horizontal pipe section to slide and adjust in the X direction, and the two Y-direction clamping assemblies clamp and adjust the horizontal pipe section in the Y direction until the center point of the vertical projection of the joint of the horizontal pipe section and the vertical pipe section coincides with the center point of the turntable. At this time, the rotating assembly can drive the horizontal pipe section to rotate smoothly.

[0011] According to the above technical solution, preferably, the upper clamping mechanism includes a vertical cylinder and a limit clamping seat. The fixed part of the vertical cylinder is fixedly connected to the support arm, and the free end of the vertical cylinder is fixedly connected to the limit clamping seat. The limit clamping seat is adapted to the upper end of the vertical pipe section.

[0012] It can be seen that in the above technical solution, the free end of the vertical cylinder pushes the limit clamping seat to lock the vertical pipe section, so as to lock and limit the vertical pipe section and the horizontal pipe section vertically.

[0013] According to the above technical solution, preferably, the lifting assembly includes a vertical slide rail, a second motor, a second lead screw unit and a vertical slide table. The vertical slide rail and the second motor are both vertically fixedly connected to the support arm. The second motor drives the second lead screw unit, and the second lead screw unit is in threaded cooperation with the vertical slide table. The angle adjustment assembly is fixedly connected to the vertical slide table.

[0014] It can be seen that in the above technical solution, the second motor drives the second lead screw unit, and the second lead screw unit drives the vertical slide table and the angle adjustment assembly to adjust vertically and smoothly, with high precision and sensitive response.

[0015] According to the above technical solution, preferably, the angle adjustment assembly includes a fixed disk and an adjustment disk that are coaxially rotatably connected. The fixed disk is fixedly connected to the vertical slide table, and the arc voltage tracking slide plate is fixedly connected to the adjustment disk.

[0016] The beneficial effects of the present utility model are as follows: The staff adjusts the lower clamping mechanism and the upper clamping mechanism so that the lower clamping mechanism clamps and locks the horizontal pipe section, and the upper clamping mechanism clamps and locks the vertical pipe section. At this time, the intersection line of the horizontal pipe section and the vertical pipe section intersects at the set position. Then, the lifting assembly drives the angle adjustment assembly, the arc voltage tracking slide plate, and the welding torch to slide up and down. The angle adjustment assembly drives the arc voltage tracking slide plate and the welding torch to rotate by a set angle. At this time, the welding position of the welding torch is directly opposite to the splicing position of the horizontal pipe section and the vertical pipe section. As the lower clamping mechanism drives the horizontal pipe section to rotate smoothly, the lifting assembly synchronously fine-tunes the up and down sliding, thereby effectively improving the welding efficiency of the pipe-to-pipe intersection line while ensuring precision, and having great market promotion value.

Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the utility model.

[0025] In the description of the utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the utility model.

[0026] As shown in the figure, the utility model provides a tube-to-tube intersecting line TIG automatic welding system, which includes a lower clamping mechanism 1, an upper clamping mechanism 2, a welding torch adjusting mechanism 3 and a welding torch 4.

The angle adjusting assembly 8 drives the arc voltage tracking slide plate 9 and the welding torch 4 to rotate by a set angle. At this time, the welding position of the welding torch 4 is facing the splicing point of the horizontal pipe section 5 and the vertical pipe section 6. As the lower clamping mechanism 1 drives the horizontal pipe section 5 to rotate smoothly, the lifting assembly 7 synchronously fine-tunes the up and down sliding, so as to effectively improve the welding efficiency of the tube-to-tube intersecting line while ensuring the accuracy, and has great market promotion value.
