Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a novel welding rod mechanism of a boring and welding integrated machine. Background Art

[0002] The boring and welding machine is widely used in the field of welding and boring of engineering machinery. The working principle of the boring and welding machine mainly depends on the spindle, screw assembly and working head assembly inside it. The spindle rotates through the driving component, and the power head drives the spindle to rotate, thereby driving the working head assembly sliding on the spindle to rotate. The screw assembly is responsible for driving the working head assembly to slide horizontally on the spindle. The working head assembly includes a boring tool assembly and a welding gun assembly, which are used for boring and welding respectively.

[0003] However, one end of the welding rod of the existing boring and welding machine is fixed in the bearing seat by a reducing sleeve. The welding rod is inserted through the reducing sleeve, resulting in a gap between the reducing sleeve, the bearing seat and the welding rod. In addition, the weight of the cable acts on one end of the welding rod, which will cause the side of the welding rod where the gun head is installed to tilt upward, eventually causing the welding gun to rotate eccentrically during operation, resulting in problems such as skewed welding and uneven size and thickness of welds, and also causing boring to be time-consuming and energy-consuming. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the utility model is to provide a novel welding rod mechanism of a boring and welding integrated machine, which has a compact structure, is easy to disassemble and assemble, has high concentricity, and can ensure processing quality.

[0006] A first welding rod, wherein the first welding rod is hollow;

[0007] A second welding rod, wherein the second welding rod is hollow and arranged opposite to the first welding rod;

[0008] A welding gun assembly, wherein the welding gun assembly is arranged between the first welding rod and the second welding rod, and the two sides of the welding gun assembly are detachably connected to the first welding rod and the second welding rod respectively, and a through groove communicating with the hollow portion thereof is formed on the side wall of the second welding rod, and the through groove cooperates with the welding gun assembly.

[0009] Preferably, the welding gun assembly includes a rotating welding rod, a gun head, a goose tube, a conductive nozzle and a nozzle.
