Abstract

The invention provides a welding machine head for deep-hole surfacing welding. The whole machine head is supported and positioned by a fixed adjustment device. The infinite rotation device is fixed on the fixed adjustment device. The end of the long arm assembly is fixed with a welding torch assembly, the wire feeding mechanism is fixed on the infinite gyration device, and the welding wire is delivered to the welding torch position of the welding torch assembly, and a camera device is also installed on the welding torch assembly. The present invention supports and positions the entire machine head through the fixed adjustment device, and the rotary motor drives the extension arm to rotate infinitely through the connection device to realize continuous positive and negative rotary welding functions; the extension arm assembly and the fixed adjustment device can be adjusted according to the depth of the weld seam of the workpiece The position of the welding torch and the arc voltage tracking device can adjust the radius of gyration of the welding torch according to workpieces with different inner diameters, and at the same time track the arc voltage in real time during 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...
