Wire feeding mechanism

Abstract

The invention discloses a wire feeding mechanism which comprises an upper cover, a machine body, a step driving mechanism, at least two wire feeding mechanisms and a positioning mechanism, wherein the step driving mechanism is mounted in the machine body through a bolt, and fixed-length output of a welding wire is realized through the arrangement of the step driving mechanism; the upper cover is movably connected with the machine body in an opening-closing way, and is provided with an opening-closing mechanism which can realize flexible opening and closing of the upper cover to facilitate insertion of the welding wire at a wire feeding state; each wire feeding mechanism comprises two wire guiders fixed on the machine body and a wire feeding gear, the two wire guiders are provided with through holes that are located on the same horizontal axis after the two wire guiders are fixed, and the wire feeding gear is arranged between the two wire guiders and connected with the step driving mechanism; and the positioning mechanism is mounted in the upper cover, is located above the wire feeding gears, and can be closely combined with the wire feeding gears during operation. According to the wire feeding mechanism provided by the invention, the upper cover can be opened to facilitate insertion of the welding wire, the working continuity is high, fixed-length output of the welding wire is realized, the production efficiency is improved, and waste is avoided.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to a wire feeding mechanism of a welding machine. Background technique [0002] The welding machine is equipped with a wire feeding mechanism to realize automatic production, but the fuselage of the wire feeding mechanism in the prior art is integrally formed, and manual wire threading before welding cannot observe the wire threading situation in real time. It is easy to bend at the time, and needs to be repeatedly interspersed, which cannot ensure a 100% success rate, and the operation is cumbersome and complicated; the existing wire feeding mechanism only has a wire feeding gear inside, and the welding wire is likely to shift when the welding machine is working , thereby affecting the quality of welding; in addition, the existing wire feeding mechanism can only coordinate with one welding machine, and its work efficiency is low and the cost is high; in addition, the existing wire ...
