Problems solved by technology

[0010] In order to overcome the high cost of electrodes in the prior art, frequent grinding and repairing is required during use; the length of the electrode inserted into the honeycomb is small and the rigidity is poor; the length of the electrode inserted into the honeycomb is not fixed, and the welding quality is unstable. The invention provides a A small honeycomb component spot welding movable electrode, the length of the electrode can be determined according to the height of the honeycomb, so that the length of the electrode extending into the honeycomb is relatively fixed, which can significantly improve the welding quality

Embodiment Construction

[0031] refer to figure 1 . The movable electrode is made of suitable high-strength enameled wire, which is processed into a figure 1 The active electrodes are shown. After the electrode is formed, the insulating varnish on its pressurized conductive surface 4 and welding contact surface 3 parts can be carefully removed. For example, image 3 For the honeycomb part shown, the diagonal size of the honeycomb is 1mm, and the high-strength enameled wire of φ0.7mm can be used to make the movable electrode; the diagonal size of the honeycomb is 2.0mm, and the high-strength enameled wire of φ1.6mm can be used to make the movable electrode electrode.

Abstract

A movable electrode for the point welding on sall cellular member is made up of a segment of high-strength enamelled wire, flattening and bending its upper segemnt, and removing the enamel from its contact surface and electric conducting surface. Its welding method includes such steps as inserting said movable electrode in the cellular member, making electric conducting and pressing block on the inner surface of welding tongs in contact with the point to be welded, and closing the power switch for electric point welding.

Description

Technical field: [0001] The invention relates to a movable electrode for spot welding of a small honeycomb component and a welding method. Background technique: [0002] Small honeycomb components have become necessary components of modern aero-engines. [0003] Small honeycomb structures are often welded by micro capacitor energy storage spot welding. Before welding, the strip-shaped honeycomb profiles are cut along the Figure 5 The dotted line locations shown cut the two ends apart and butt them together exactly. The existing technology is to use Figure 6 The miniature welding pliers shown perform point-by-point spot welding. [0004] Due to the small size of a single honeycomb body of a small honeycomb structure, for example, the diagonal line of a single honeycomb of a honeycomb structure used in a 10A engine is only 1 mm, and the wall thickness is only 0.04 mm. Figure 6 When welding with the miniature welding pliers shown, there are the following problems: [00...
