Intelligent welding rod distribution device

Abstract

The invention discloses an intelligent welding rod distributing device, which comprises a frame, on which a distributing main shaft is rotatably installed, on which a spline barrel is arranged, on which a plurality of distributing key grooves are arranged, and the side walls of the distributing key grooves are key grooves The fixed wall and the movable wall of the keyway, the fixed wall of the keyway or the corresponding movable wall of the keyway is fixed with the bottom wall of the keyway; the movable wall of the keyway and the fixed wall of the keyway adjacent to the opposite side of rotation are provided with an intersection forming the outer peripheral surface of the spline cylinder. Enclosing structure, opening stoppers and occlusal elastic forcers are respectively set between the movable walls of each keyway and the distribution main shaft, distribution drives are provided between the distribution main shaft and the frame; There is a bar-eating opener on the side, and a bar-spraying opener on the opposite side of the spline barrel at the low point of rotation. The invention can adapt to the bending and eccentricity of welding rods for counting and discharging, the counting and discharging is orderly and reliable, and the damage of drug skin and damage of welding rods can be reduced.

Description

technical field [0001] The invention relates to the technical field of welding accessories, in particular to an intelligent welding rod distribution device. Background technique [0002] The welding rod is a metal strip that is melted and filled at the joint of the welding workpiece during gas welding or electric welding. It is widely used in many occasions such as large-scale machining, metal manufacturing, and welding teaching. The welding rod is mainly composed of a metal welding core and a coating covering the metal welding core. In order to ensure the effect of welding, the finished electrode has strict requirements in terms of eccentricity, bending and other aspects. Among them, the bending degree is usually required to be no more than 1mm (non-cold drawn welding core is not more than 1.5mm); the eccentricity requirements of electrodes with different diameters are different, and the larger the diameter of the electrode, the higher the eccentricity requirements.

Problems solved by technology

At present, the allocation of welding rods mainly relies on manual records, which is very cumbersome and has a high error rate

At present, although there are also welding rod distribution devices that use spline cylinders to realize single counting and discharging, such as the rotating cylinder disclosed in the invention patent application with the application number "201911273760.9" and the name "An Intelligent Distribution Device and Method for Welding Rods" Meter structure, but the actual use effect is not ideal, specifically as follows: (1) In order to prevent redundant electrodes from entering the keyway, each keyway on the surface of the spline barrel is usually designed with a fixed width. Counting and discharging, but for most electrodes that are slightly bent or partially eccentric, the electrodes often cannot enter the keyway normally, and normal counting and discharging cannot be completed, so the actual adaptability of the spline barrel structure is poor. ; (2) In order to improve the adaptability effect described in (1), the keyway of the spline cylinder is usually slightly larger than the diameter of the welding rod to adapt to bending and partial eccentricity, but this will cause two There are two kinds of phenomena, one is that after one electrode enters the keyway smoothly, other electrodes are piled up in the keyway notch in sequence, and the other is that the electrode with bending or partial eccentricity still cannot enter the keyway normally; in the actual use process, the spline barrel rotates The direction is usually equipped with a structure such as a rigid baffle to block and remove redundant electrodes. Because the electrode is different from other screw-shaped materials, it has a layer of coating on the outside, so the forced removal of the above rigid baffle will form a butt joint between the keyway and the keyway. This will not only easily cause damage to the outer coating and affect the subsequent welding performance, but will even cause damage to the electrode, resulting in waste of electrode resources; It is forced into the keyway, but the welding rod is also stuck in the keyway. When the keyway rotates to the low point of the spline barrel, it cannot fall out freely, and the counting and discharging cannot be performed normally.
