Current conduction nozzle

Abstract

The invention relates to a current conduction nozzle which comprises a current conduction nozzle body, a shell and a spring adjusting device. The shell is provided with a current conduction nozzle body installing hole, and a plurality of threaded installing holes are formed in the shell wall and are symmetrically arranged around the current conduction nozzle body installing hole; the spring adjusting device comprises springs, bosses and threaded connecting pieces which correspond to the threaded installing holes in a one-to-one manner; the current conduction nozzle body is formed by two matching bodies, the matching faces of the two matching bodies are each provided with a semi-groove, and the two semi-grooves are combined to form a wire penetrating hole; each matching body sequentially comprises an axial positioning section, a matching section and an extending-out section from the wire inlet end and the wire outlet end; the current conduction nozzle body and the shell are installed ina matched manner, the axial positioning sections are located outside the shell, the matching sections are located inside the shell, and the extending-out sections extend out of the shell. The currentconduction nozzle solves the problem that an existing current conduction nozzle inner hole is difficult to machine, and the matching precision of the diameter of the current conduction nozzle inner hole and the wire diameter is low; and the current conduction nozzle has the beneficial effects that machining is easy, the matching accuracy is high, adjustment is facilitated, efficiency is high, andthe service life is long.

Description

technical field [0001] The invention relates to a conductive tip. Background technique [0002] The inner hole of the contact tip is a slender hole, which is relatively difficult to process, and it is difficult to meet the process requirements of the contact tip. Generally, in order to make the welding wire pass through the inner hole of the contact tip smoothly, the diameter of the inner hole of the contact tip must be processed larger than the diameter of the welding wire, so that the following problems arise: First, irregular shaking occurs when the welding wire is drawn out, especially After the wear of the inner hole becomes larger, the swaying range is greater. Once the inner hole is worn or out of round, it will directly affect the welding quality; second, there is no self-compensation, and the machine-made welding wire is in loose contact with the inner hole of the contact tip. It is a pity that the new contact tip will be burned when it is first arced, and the wast...
