Embodiment 1

[0049] Such as figure 1 and figure 2 As shown, this embodiment provides a welding torch 1 , which includes: a welding torch body 11 , a wire feeding nozzle 12 and a camera 13 . The wire feeding nozzle 12 and the camera 13 are arranged on the welding torch body 11 .

[0050] The welding torch body 11 is a cylindrical structure, with a nozzle 111 at one end and a clamping motor 112 at the other end. A clamping mechanism and a tungsten electrode 113 are arranged inside the welding torch body 11. One end of the tungsten electrode 113 is clamped by the clamping mechanism, and the other end is provided with a clamping motor 112. One end protrudes from the nozzle 111 . The clamping motor 112 is connected with the clamping mechanism through a bevel gear transmission, and controls the clamping mechanism to clamp or loosen the tungsten pole, so as to facilitate the operation of automatically replacing the tungsten pole.

[0051] The axial direction of the wire feeding nozzle 12 is i...

Embodiment 2

[0066] Such as Figure 4 and Figure 5 As shown, this embodiment provides a welding device, including: a base 2, a wire feeding mechanism 3, an adjustment mechanism 4, and the welding torch 1 of Embodiment 1.

[0067] The adjusting mechanism 4 is arranged on the base 2 and is connected with the welding torch 1 for adjusting the position of the welding torch 1 relative to the base 2 to adjust the position of the welding torch 1 relative to the workpiece.

[0068] The wire feeding mechanism 3 is arranged on the base 2 and connected with the wire feeding nozzle 12 of the welding torch 1 through the welding wire, and is used for pulling the welding wire through the wire feeding nozzle 12 .

[0069] In this embodiment, the adjustment mechanism 4 includes a two-dimensional linear drive mechanism 41, the two-dimensional linear drive mechanism 41 is connected between the base 2 and the welding torch 1, and is used to drive the welding torch 1 to reciprocate relative to the base 2 alo...

Embodiment 3

[0079] This embodiment provides a welding system, which includes a welding machine, a control system and the welding device of Embodiment 2.

[0080] The base 2 of the welding device is arranged on a mobile trolley, and the welding machine is connected with the welding device to drive the welding device to run.

[0081] The camera 13 of the welding device is electrically connected with the control system, and is used for transmitting the real-time camera signal to the control system,

[0082] The control system is electrically connected with the welding machine and the adjustment mechanism 4 respectively, and is used to judge whether the nozzle 111 of the welding torch 1 and the wire feeding nozzle 12 are facing the area to be welded of the workpiece according to the real-time camera signal, if so, control the welding machine to start; if not, then Control the action of the adjustment mechanism 4 to adjust the position of the welding torch 1 relative to the base 2 until the no...

Abstract

The invention provides a welding gun, a welding gun device and a welding system. The welding gun comprises a welding gun body, a wire feeding nozzle and a camera, the wire feeding nozzle and the camera are arranged on the welding gun body, one end of the welding gun body is provided with a nozzle, the axial direction of the wire feeding nozzle is inclined relative to the axial direction of the nozzle, and an outlet of the wire feeding nozzle is close to an outlet of the nozzle; and a lens of the camera faces the to-be-welded area of a workpiece, and the visual angle of the camera at least covers the outlet of the nozzle, the outlet of the wire feeding nozzle and the to-be-welded area of the workpiece. The camera is installed on the welding gun so as to shoot the images of the outlet of the nozzle, the outlet of the wire feeding nozzle and the to-be-welded area of the workpiece in real time, the camera can be electrically connected to a remote control system so that the position of the welding gun can be remotely controlled and adjusted, and therefore operators are prevented from being exposed in the nuclear welding environment.

Description

technical field [0001] The invention specifically relates to a welding torch, a welding device and a system. Background technique [0002] For nuclear power equipment that has expired in service, it needs to be decommissioned accordingly. One of the links is the welding and sealing of special mechanical components, so as to ensure that the radioactive materials in it will not cause unacceptable harm to the public and the environment during the safe storage period. harm. [0003] Due to the high level of radioactivity in the area where nuclear power equipment is located, personnel cannot work at close range, and it is necessary to use remote control to carry out welding and sealing operations. Conventional welding equipment is difficult to meet this requirement. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a welding torch remotely controlled by an auxiliary control system, and to provide a welding device and a...
