Electrode rotation electric conduction structure

Abstract

The invention discloses an electrode rotation electric conduction structure. The electrode rotation electric conduction structure comprises an electrode shaft and an electrode holder, an electrode wheel is installed at one end of the electrode shaft, and the electrode shaft is sleeved with the electrode holder and provided with shaft shoulders of which the sections are trapezoid or rectangular. The electrode holder is provided with an annular clamp, silver electrode tiles are arranged between the shaft shoulders and the annular clamp, and the annular clamp comprises a semicircular upper clamp body and a semicircular lower clamp body connected with the upper clamp body in a butt joint mode. The upper clamp body and the lower clamp body are encircling pressing parts of which the radius is changeable. A shrinkage gap is prearranged between the upper clamp body and the lower clamp body, and pressing pieces for pressing the electrode tiles are arranged between the upper clamp body and the corresponding electrode tile as well as between the lower clamp body and the corresponding electrode tile. Because the clamping radius of the annular clamp for clamping the electrode tiles is changeable, the radius of the annular clamp is adjusted and shrunk, the abrasion loss of the silver pieces can be offset, it is ensured that the electric conduction structure keeps original pressure all the time, and therefore the electric conduction effect of the electric conduction structure can be ensured without frequently replacing the silver pieces.

Description

technical field [0001] The invention relates to a conductive structure, in particular to a conductive structure for electrode rotation. Background technique [0002] The conduction method of the movable conductive structure of the electrode shaft and the electrode seat inside the electrode of the traditional seam welding machine is to compress the electrode seat by a spring, so that the tapered surface of the electrode shaft and the electrode seat fit and conduct electricity. In order to achieve low rotational resistance and strong electrical conductivity in the above structural form, it is first necessary to ensure the matching accuracy between the electrode holder, the electrode tile and the electrode shaft, and secondly to ensure that the compression force of the spring reaches the maximum within the allowable range of rotational resistance. , the strength is just right. Due to the high requirements for matching accuracy and spring force, the commonly used conductive str...

AI Technical Summary

Problems solved by technology

Due to the high requirements for matching accuracy and spring force, the commonly used conductive structures are complex, difficult to install and maintain, high processing requirements and high manufacturing costs, and are not suitable for making small tiles.

In the existing commonly used conductive structures, if the spring force is too large, the friction between the electrode holder and the electrode shaft will be too large, causing the electrode holder to hold the electrode shaft so that the electrode shaft cannot rotate freely, and the movable guiding structure will fail; The process will inevitably lead to the wear of the electrode tile, that is, the silver sheet. After the electrode tile is worn and thinned, there will be a displacement between the electrode shaft and the electrode tile. The spring pressure cannot be adjusted, so the spring force will continue to weaken, resulting in insufficient pressure, resulting in poor electrical conductivity. And bulky equipment is bulky
