Abstract
The present invention relates to the special-shaped spot welding bottom electrode probeed into inside outer ring assembly, including electrode body (1) and electrode contacts (2), electrode body (1) is arranged in spot welding electrode mounting seat, and the internal water cooling passage of electrode body (1) is connected with mash welder water cooling plant；The upper end both sides of electrode body (1) are respectively symmetrically provided with the boss (3) with loop configuration, and the aperture for placing electrode contacts (2) is provided with the top of boss (3).The present invention is not required to reuse fixture clamping outer shroud and locating piece, and special-shaped bottom electrode directly ensures the relative position of outer shroud and locating piece；Special-shaped electrode, which is probeed into, carries out spot welding inside outer shroud, fundamentally change the welding manner of original single-side double-point, efficiently solve in welding process the generation of " shunting " phenomenon, and then it is unqualified to avoid the caused joint quality of nugget skew；Electrode contacts are detachable, it is to avoid electrode is integrally scrapped caused by export license.
Description
Technical field
The invention belongs to spot-welding technology equipment Design field, it is related to the processing of the spot welding to aeronautical product outer ring assembly.
Background technology
Obturator outer ring assembly is connected by outer shroud with locating piece in spot welding mode in fuel regulator, due to that can probe into
Special-shaped spot welding lower electrode arrangement inside outer shroud is complicated and intensity is difficult to reach requirement, so the spot welding of outer ring assembly is generally used
Outer shroud and locating piece, were both assembled on frock directly with common upper/lower electrode pair by the spot welding mode by middle conductor of frock
Point.This spot welding mode can cause the shunting of welding current, cause serious when welding the outer ring assembly that thin and thick differs greatly
Nugget is offset, and causes quality of weld joint to be difficult to reach design requirement.
The content of the invention
The purpose of the present invention is：A kind of special-shaped spot-wedling electrode is designed, changes original single-side double-point spot welding mode, it is to avoid shunting
Phenomenon occurs, and probes into and spot welding is carried out inside outer ring assembly, and solving nugget skew causes the underproof problem of joint quality.
The technical scheme is that：Design the special-shaped spot welding bottom electrode probeed into inside outer ring assembly, including electrode body 1
With electrode contacts 2, electrode body 1 is arranged in spot welding electrode mounting seat, the internal water cooling passage and mash welder of electrode body 1
Water cooling plant is connected；The upper end both sides of electrode body 1 are respectively symmetrically provided with the boss 3 with loop configuration, at the top of boss 3
It is provided with the aperture for placing electrode contacts 2.
The loop configuration of boss 3 and the annular groove of outer ring assembly coordinate.
During welding, the contact area of the locating piece of electrode contacts 2 and outer ring assembly is less than the outer of Top electrode and outer ring assembly
The contact area of ring.
Electrode body 1 and the material of Top electrode are chromium-zirconium-copper, and the material of electrode contacts 2 is CuW80.
It is an advantage of the invention that：It is not required to reuse fixture clamping outer shroud and locating piece, special-shaped bottom electrode directly ensures outer shroud
With the relative position of locating piece；Special-shaped electrode, which is probeed into, carries out spot welding inside outer shroud, fundamentally change original single-side double-point
Welding manner, efficiently solves in welding process the generation of " shunting " phenomenon, and then avoids joint matter caused by nugget skew
Amount is unqualified；Electrode contacts are detachable, it is to avoid electrode is integrally scrapped caused by export license.
