Abstract

The invention provides a welding head for deep hole surfacing. The whole head is supported and positioned through a fixed adjusting device, wherein a wireless rotating device is fixed to the fixed adjusting device, an extension arm assembly is fixed to the wireless rotating device, a welding gun assembly is fixed to the end of the extension arm assembly, a wire feeding mechanism is fixed to the wireless rotating device and conveys welding wires to the welding gun position of the welding gun assembly, and a camera device is further installed on the welding gun assembly. The whole head is supported and positioned through the fixed adjusting device, a rotating motor drives an extension arm to rotate infinitely through a connecting device, and the continuous forward and reverse rotating welding function is achieved; and the extension arm assembly and the fixed adjusting device can adjust the welding gun position according to the workpiece weld depth, an arc voltage tracking device can adjust the rotating radius of a welding gun according to workpieces with different inner diameters, and meanwhile arc voltage real-time tracking is carried out in the welding process.

Description

technical field [0001] The invention belongs to the technical field of welding heads, in particular to a welding head used for deep-hole surfacing. Background technique [0002] The current petrochemical nuclear power pressure vessel equipment needs to be manufactured by welding, and the inner wall surfacing of the vessel connection usually adopts vertical or horizontal pipe inner wall surfacing equipment. These welding equipment are usually equipped with a manipulator, a three-dimensional adjustment mechanism and a rotary chuck support, etc., which are suitable for fixed stations, and the small size is convenient for welding of moving and flipping workpieces. Therefore, these conventional welding equipments occupy a large space and are not convenient for moving and lifting; they are not suitable for assembly site welding and welding places with limited space. Contents of the invention [0003] In order to solve the above problems, the present invention provides a welding...
