[0035] Specifically, the transmission mechanism 2 includes a motor 21 and a reduction gear box 22, and the motor 21 is connected to the reduction gear box 22. The mounting base 1 is also fixedly connected to the connecting base 11, and the reduction gear box 22 is fixedly arranged on the connecting base 11.

[0036] In this embodiment, the reduction gearbox 22 includes a wire feeding assembly 221, a straightening wheel 222 and a wire feeding bracket 223; the wire feeding assembly 221 is arranged on one side of the reduction gearbox 22, and the straightening wheel 222 and the wire feeding bracket 223 are arranged on the other side of the reduction gearbox 22; the wire feeding bracket 223 is also connected to a pressure adjustment handle 224.

[0037] The submerged arc welding gun 3 includes a welding gun rod 31 , a flux funnel 32 and a welding nozzle 33 which are connected in sequence.

[0038] More specifically, the connecting base 11 is also fixedly connected to a first mounting bracket 13 , and the first mounting bracket 13 is used to mount the line laser detector 4 .

[0039] Furthermore, the line laser detector 4 also includes a plurality of laser ranging probes, each of which corresponds to the X-axis, Y-axis and / or Z-axis direction.

[0040] Example 2

[0041] One of the implementation methods of the welding device with line laser detection of the utility model is as follows: Figures 1 to 6 As shown, the main technical solution of this embodiment is basically the same as that of Example 1. The features not explained in this embodiment are explained in Example 1 and will not be repeated here. The difference between this embodiment and Example 1 is:

[0042] It also includes: an in-place detection mechanism; the in-place detection mechanism includes: an in-place switch 5 and a swing arm 51; one end of the swing arm 51 is connected to the in-place switch 5, and the other end of the swing arm 51 is also provided with a transition wheel 511.

[0043] As the welding device descends, when the transition wheel 511 contacts the workpiece, the swing arm 51 swings due to the extrusion. When the swing arm 51 swings to the corresponding position, the in-position switch 5 is triggered.

[0044] Specifically, the in-position switch 5 is fixed on one end of the second mounting bracket 52 ; the other end of the second mounting bracket 52 is provided with a mounting clamp 53 , which is fixed on the welding gun rod 31 of the submerged arc welding gun 3 through the mounting clamp 53 .

That is, the controller is electrically connected to the motor 21, the submerged arc welding gun 3, the line laser detector 4 and the in-position switch 5.

[0050] Specifically, the controller obtains high-precision position information in real time through the line laser detector 4, so that the welding position can be adjusted accordingly to follow the detected position, ensuring that the weld position has no deviation.

[0051] The controller uses the in-position switch 5 at the front end of the welding direction as a sensor to detect the position of the welding workpiece or the welding length. After detecting the position to be welded in advance, it can send a signal to the flux delivery switch of the submerged arc welding gun 3, effectively reducing the accumulation and waste of flux at the tail end, and improving the welding quality and aesthetics.
