Embodiment 1

[0056] Such as figure 1 As shown, the first embodiment provides a welding device for pipe fittings, which includes two sets of rotatable workbenches 2 and a welding assembly 5, and uses two sets of rotatable workbenches 2 to drive the pipe fittings 12 to rotate infinitely, avoiding the need for cables during welding Without interference, barrier-free welding of the pipe fitting 12 can be realized.

[0057] In the first embodiment, two sets of rotatable workbenches 2 are arranged up and down opposite to each other. A set of clamping assemblies 3 are respectively provided on these two sets of workbenches 2, and each set of clamping assemblies 3 is provided with a pipe fitting 12 for clamping. The clamping space, the pipe fittings 12 to be welded can be reliably clamped and fixed in the clamping space, so as to facilitate the subsequent welding process of the pipe fittings 12; 2 are coaxially arranged, that is to say, when two pipe fittings 12 to be welded are respectively clamped...

Embodiment 2

[0072] The structure of the pipe fitting welding device provided in the second embodiment is basically the same as that in the first embodiment, and the similarities need not be repeated. One of the clamping assemblies 3 has the same structure, that is, the clamping assembly 3 includes a clamp 14 and a fixed block 13; and the other set of clamping assemblies 3 includes a chuck fixed on the worktable 2, and the axis of the chuck is provided with There is a clamping space, and at least three claws are respectively arranged around the clamping space, and the pipe fitting 12 to be welded is inserted at the central axis position between each claw, and the claws are pressed from multiple directions, so that the pipe fittings 12 is fixed in the clamping space. This setting is because according to the requirements of the EMU copper tube welding process, when welding between the clip and the copper tube, it is usually impossible to use the method of pressing and clamping up and down at ...

Embodiment 3

[0074] Such as Figure 4 As shown, on the basis of the above-mentioned embodiment 1 or embodiment 2, this embodiment 3 provides a pipe fitting welding system, the frame 1 of the system is fixed with the control device 4 and the above-mentioned pipe fitting welding device, The system uses the control device 4 to control the welding torch 11 of the pipe welding device to weld the rotating pipe 12, the welding assembly 5 is fixed, and the workbench 2 is used to drive the pipe 12 to rotate infinitely, which avoids cable interference during welding and can realize Hassle-free welding of pipe fittings 12.

[0075] Specifically, the control device 4 of the system is connected to the workbench 2 and the welding assembly 5 respectively, and the control device 4 is provided with a workbench 2 control module, a welding torch 11 control module, a wire feeding control module, an arc length tracking module and a data processing module . The workbench 2 control module is respectively conne...

Abstract

The invention relates to the technical field of welding, in particular to a welding device, a welding system and a welding method for pipes. The mechanism comprises two rotatable worktables which are arranged oppositely up and down; a clamping component is arranged on each of the two worktables; each clamping component is provided with a clamping space for clamping a pipe; each clamping space is arranged coaxial with the corresponding worktables, and the worktables are arranged coaxially; two to-be-welded pipes are separately clamped in the two clamping spaces oppositely, and are driven to rotate separately by the two worktables; at least one clamping component comprises a clamp and a fixed block; the clamp and the fixed block are separately arranged on the corresponding worktable oppositely, and a clamping space is formed between the clamp and the fixed block; a welding component is arranged between the two clamping components and is used for welding a connection part between the rotating two pipes; and the welding system and the welding method are disclosed based on the welding mechanism; and the problem that existing copper pipe welding mainly relies on manual operation and is tedious, so that welding is inconvenient is solved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a pipe fitting welding device, a welding system and a welding method. Background technique [0002] Because copper tubes have the advantages of good thermal conductivity, easy processing and long service life, copper tubes are often used in current EMUs, and according to specific applications, copper tubes need to be processed in various ways, such as bending, cutting, welding, etc. ; Among them, welding is one of the most common processing techniques in pipe fittings processing. [0003] At present, in the production process of rail vehicles in my country, the welding production process of EMU copper pipes usually adopts the flame brazing process. In this process, silver-based solder, containing about 45% silver, is manually welded by workers, and the entire welding process To meet the demand of producing 8 vehicles in 1.5 days, about 176 copper pipes are produced and welded ev...
