Wire feeding mechanism of welding machine

Abstract

The invention discloses a wire feeding mechanism of a welding machine. The wire feeding mechanism comprises a machine base, a wire feeding gear, a wire clamping induction wheel, a welding wire guide block, a first sensor and a second sensor, wherein the wire clamping induction wheel is rotatably arranged on a slide plate which is arranged on the machine base and capable of sliding leftwards and rightwards, the left end of the slide plate is connected with a plurality of pressure springs, the ends of the pressure springs are fixed on the left end of the machine base, the wire feeding gear and the wire clamping induction wheel are arranged on the machine base in a leveled manner, an interval through which a welding wire penetrates is formed between the wire feeding gear and the wire clamping induction wheel, the welding wire guide block is arranged just above the interval, the first sensor is arranged on the machine base and just opposite to the welding wire guide block, and the second sensor is arranged on the slide block and just opposite to the wire clamping induction wheel. The wire feeding mechanism of the welding machine is reasonable in structure and smart in design, and can precisely and reliably detect whether soldering tin exists and whether the wire is normally fed, so that the production efficiency is improved, and the lack of welding is eliminated.

Description

technical field [0001] The invention relates to welding equipment, in particular to a wire feeding mechanism of a welding machine. Background technique [0002] In the prior art, when using a welding machine for automatic welding, if it is not found in time that the welding wire is used up or the welding wire is blocked, or when it is not 100% detected, there will often be a large number of poorly welded products, which will bring a lot of trouble to the enterprise. A lot of losses. [0003] How to accurately detect whether the welding wire is used up or the welding wire is blocked, so as to avoid the occurrence of missing welding, has become an urgent need in the industry. Contents of the invention [0004] The purpose of the present invention is to solve the above problems and provide a reasonably designed wire feeding mechanism of a welding machine, which can accurately and reliably detect whether there is solder and whether the wire is fed normally, thereby improving ...
