[0047] See also Figures 1 to 4 As shown, the butt-welding device provided by the present application includes a first clamping device 101, a second clamping device 102 and a steering welding device 103; the first clamping device 101 and the second clamping device 102 are arranged relatively to each other, and are used to clamp the first object to be welded 104 and the second object to be welded 105 respectively, and butt the welding end of the first object to be welded 104 and the welding end of the second object to be welded 105; a steering welding device 103 is arranged between the first clamping device 101 and the second clamping device 102, and the steering welding device 103 can move circumferentially around the butt joint of the first object to be welded 104 and the second object to be welded 105 to weld the butt joint circumferentially.

[0048] Specifically, the butt-welding device includes a first clamping device 101, a second clamping device 102 and a steering welding device 103. The first clamping device 101 clamps the first object to be welded 104, the second clamping device 102 clamps the second object to be welded 105, and the welding ends of the first object to be welded 104 and the second object to be welded 105 are butted, and the butt joint is the welding joint. The steering welding device 103 can rotate relative to the first clamping device 101 and the second clamping device 102, so that the welding gun of the steering welding device 103 moves around the butt joint and welds the butt joint. For the first object to be welded 104 and the second object to be welded 105 with a long welding length, the first object to be welded 104 and the second object to be welded 105 are fixed, and the steering welding device 103 is rotated to weld the butt joint, which can save more energy consumption.

[0049] The butt girth welding device provided in the present application realizes girth welding of the first object to be welded 104 and the second object to be welded 105 through the first clamping device 101, the second clamping device 102 and the steering welding device 103, thereby saving manpower and improving production efficiency.

[0050] In an optional solution of this embodiment, the first clamping device 101 includes a first clamping seat 106, a first clamping cover 107 and a first lifting device 108. A clamping opening is formed between the first clamping seat 106 and the first clamping cover 107 to clamp the first object to be welded 104. The first lifting device 108 is used to drive the first clamping cover 107 to move so that the first clamping seat 106 and the first clamping cover 107 are separated or brought closer.

[0051] The second clamping device 102 includes a second clamping seat 109, a second clamping cover 110 and a second lifting device 111. A clamping opening is formed between the second clamping seat 109 and the second clamping cover 110 to clamp the second object to be welded 105. The second lifting device 111 is used to drive the second clamping cover 110 to move so as to separate or approach the second clamping seat 109 and the second clamping cover 110.

[0052] In this embodiment, the first clamping device 101 includes a first clamping seat 106, a first clamping cover 107 and a first lifting device 108. After the first lifting device 108 lifts the first clamping cover 107, the first object to be welded 104 can be placed between the first clamping seat 106 and the first clamping cover 107; when the first object to be welded 104 is placed in the clamping opening between the first clamping seat 106 and the first clamping cover 107, the first lifting device 108 can lower the first clamping cover 107, so that the first clamping seat 106 and the first clamping cover 107 clamp the first object to be welded 104, thereby ensuring that the object to be welded is reliably fixed during welding.

[0053] The second clamping device 102 is used to clamp the second object to be welded 105 , which is similar to the first clamping device 101 and will not be described in detail herein.

[0054] In an optional solution of this embodiment, the first lifting device 108 includes a first alignment mechanism 112 and a first lifting mechanism 113; the first alignment mechanism 112 includes a first alignment drive device 114 and a first connecting member 115, and the first lifting mechanism 113 includes a first lifting drive device 116 and a first lifting support member 117; when the first clamping seat 106 and the first clamping cover 107 are attached, the first connecting member 115 is connected to the first clamping seat 106 and the first clamping cover 107; the first alignment drive device 114 can drive the first connecting member 115 to move away from the first clamping seat 106 so that the first connecting member 115 is disconnected from the first clamping seat 106 and the first connecting member 115 is connected to the first lifting support member 117; after the first connecting member 115 is disconnected from the first clamping seat 106, the first lifting driving device 116 drives the first lifting support member 117 to move so that the first clamping cover 107 is away from the first clamping seat 106; the first alignment driving device 114 can drive the first connecting member 115 to move close to the first clamping seat 106, so that the first connecting member 115 is connected to the first clamping seat 106 and the first clamping cover 107, and the first connecting member 115 is disconnected from the first lifting support member 117;

[0055] The second lifting device 111 includes a second alignment mechanism 118 and a second lifting mechanism 119; the second alignment mechanism 118 includes a second alignment drive device 120 and a second connecting member 121, and the second lifting mechanism 119 includes a second lifting drive device 122 and a second lifting support member 123; when the second clamping seat 109 and the second clamping cover 110 are attached, the second connecting member 121 is connected to the second clamping seat 109 and the second clamping cover 110; the second alignment drive device 120 can drive the second connecting member 121 to move away from the second clamping seat 109, so that the second connecting member 121 is attached to the second clamping seat 109. The clamping seat 109 is disconnected and the second connecting member 121 is connected to the second lifting support member 123; after the second connecting member 121 is disconnected from the second clamping seat 109, the second lifting drive device 122 drives the second lifting support member 123 to move so that the second clamping cover 110 is away from the second clamping seat 109; the second alignment drive device 120 can drive the second connecting member 121 to move close to the second clamping seat 109, so that the second connecting member 121 is connected to the second clamping seat 109 and the second clamping cover 110, and the second connecting member 121 is disconnected from the second lifting support member 123.

[0056] In this embodiment, in order to ensure that the positions of the first clamping seat 106 and the first clamping cover 107 do not deviate when they are attached to each other to clamp the first object to be welded 104, the first lifting device 108 is set to include a first alignment mechanism 112 and a first lifting mechanism 113. Among them, the first alignment mechanism 112 includes a first alignment driving device 114 and a first connecting member 115. The first clamping seat 106 and the first clamping cover 107 are correspondingly provided with connecting plates. When the first clamping seat 106 and the first clamping cover 107 are attached to each other, the first connecting member 115 is simultaneously connected to the connecting plates of the first clamping seat 106 and the first clamping cover 107. The first connecting member 115 can play an alignment role, thereby ensuring that the positions of the first clamping seat 106 and the first clamping cover 107 do not deviate.

[0057] Before the first clamping cover 107 is lifted, the first alignment driving device 114 drives the first connecting member 115 to move, so that the first connecting member 115 is disconnected from the first clamping seat 106, and the first connecting member 115 still remains connected to the first clamping cover 107. The first lifting mechanism 113 includes a first lifting driving device 116 and a first lifting support member 117. During the movement of the first connecting member 115, the first connecting member 115 is connected to the first lifting support member 117. After the first connecting member 115 moves to the right position, the first lifting driving device 116 drives the first lifting support member 117 to move, and the first lifting support member 117 is connected to the first connecting member 115, and the first connecting member 115 is also connected to the first clamping cover 107, so as to realize driving the first clamping cover 107 away from the first support seat. After the first object to be welded 104 is placed between the first clamping cover 107 and the first clamping seat 106, the first lifting drive device 116 drives the first clamping cover 107 to approach and fit with the first clamping seat 106. At this time, the first connecting member 115 is connected to the first clamping cover 107 and the first lifting support member 117, and the first alignment drive device 114 drives the first connecting member 115 to move, so that the first connecting member 115 is disconnected from the first lifting support member 117 and is connected to the first clamping seat 106 and the first clamping cover 107.

[0058] The second lifting device 111 has the same principle as the first lifting device 108 , which will not be described in detail herein.

[0059] In an optional solution of this embodiment, a first slide rail assembly 124 is provided between the first alignment mechanism 112 and the first lifting mechanism 113; the first slide rail assembly 124 includes a first track and a first slider, the first track is connected to the first lifting support 117, and the first slider is connected to the first alignment driving device 114; the first connecting member 115 is provided with threads, and the first clamping seat 106, the first clamping cover 107 and the first track are all provided with threaded holes 125, so that the first connecting member 115 can be threadedly connected with the first clamping seat 106, the first clamping cover 107 and the first track;

[0060] A second slide rail assembly 126 is arranged between the second alignment mechanism 118 and the second lifting mechanism 119; the second slide rail assembly 126 includes a second rail and a second slider, the second rail is connected to the second lifting support 123, and the second slider is connected to the second alignment drive device 120; the second connecting member 121 is provided with a thread, and the second clamping seat 109, the second clamping cover 110 and the second rail are all provided with a threaded hole 125, so that the second connecting member 121 can be threadedly connected with the second clamping seat 109, the second clamping cover 110 and the second rail.

[0061] In this embodiment, the first connecting member 115 is threadedly connected with the first clamping seat 106, the first clamping cover 107 and the first track, and the first connecting member 115 needs to perform rotational movement so that it can rise and fall. The first alignment drive device 114 outputs torque to enable the first connecting member 115 to rotate counterclockwise or clockwise. Since the length of the first connecting member 115 remains unchanged, and the first connecting member 115 is connected to the first alignment drive device 114, and the first connecting member 115 supports the first alignment drive device 114, when the first connecting member 115 rises or falls, the position of the first alignment drive device 114 needs to be changed. A first slide rail assembly 124 is provided on the first lifting support member 117 so that when the first alignment drive device 114 drives the first connecting member 115 to move, it can slide relative to the immovable first lifting support member 117. The above structure realizes the alignment process of the first alignment mechanism 112.

[0062] The principle of the second alignment mechanism 118 is the same as that of the first alignment mechanism 112 and will not be described in detail herein.

[0063] In an optional solution of this embodiment, a first alignment guide mechanism 127 is further included, and the first alignment guide mechanism 127 includes a first alignment guide rod 128 and a first alignment guide plate 129; one end of the first alignment guide rod 128 is connected to the first lifting support member 117, and the other end of the first alignment guide rod 128 is connected to the first clamping cover 107; a first alignment guide plate 129 is arranged between the first alignment driving device 114 and the first clamping device 101, and the first alignment guide plate 129 is provided with a first alignment guide hole, so that the first alignment guide rod 128 can pass through the first alignment guide hole and slide;

[0064] It also includes a second alignment guide mechanism 130, which includes a second alignment guide rod 131 and a second alignment guide plate 132; one end of the second alignment guide rod 131 is connected to the second lifting support member 123, and the other end of the second alignment guide rod 131 is connected to the second clamping cover 110; a second alignment guide plate 132 is arranged between the second alignment drive device 120 and the second clamping device 102, and the second alignment guide plate 132 is provided with a second alignment guide hole so that the second alignment guide rod 131 can pass through the second alignment guide hole and slide.

[0065] In this embodiment, in order to prevent the first connecting member 115 from being skewed during the lifting and lowering process, a first alignment guide mechanism 127 is provided. The first alignment guide mechanism 127 includes a first alignment guide rod 128 and a first alignment guide plate 129. Specifically, the first clamping device 101 can be mounted on the first alignment guide plate 129, so that the immovable first clamping seat 106 is fixed on the first alignment guide plate 129. One end of the first alignment guide rod 128 is mounted on the first lifting support member 117, and the first alignment guide rod 128 passes through the first alignment guide hole provided on the first alignment guide plate 129. In the process of the first lifting driving device 116 driving the first lifting support member 117 to move, the first alignment guide hole can limit the movement of the first alignment guide rod 128.
