Abstract
The utility model relates to an electrode structure which can do single-side non-pressure resistance combined spot welding on ordinary spot-welding equipment. The connecting mode of the utility model is that an upper electrode body is sheathed with an electrode head, a lower electrode body is sheathed with a fixed sleeve, and a core pad and an insulating sleeve are sheathed with the fixed sleeve, so that the upper and the lower electrode bodies and the axial cord of the electrode head are perfected by passing through the insulating sleeve and the core pad. The utility model has the advantages of favorable neutralism, convenient dismounting, and high quality of welding spot, and omits the repair work before polishing and chromium plating.
Description
The utility model relates to a kind of electrode structure that single face does not have load mould combination spot welding that can carry out on the general point soldering equipment.
As everyone knows, spot welding is a kind of electric resistance welding method that resistance heat forms weldering nuclear when utilizing electrode to pass through weldment.Because of its productivity ratio height, no arc light toxic dust, need not additional fill metal and use solder flux, and be used widely.But some special requirement of some product requires the weldment single face not have load mould, in order to surperficial following process such as polishing, chromium plating.Realize that single face does not have the conventional method of load mould.The one, adopt special use to improve equipment, but cost is higher; The 2nd, carry out projection welding with salient point, general first punching out salient point.Sometimes, be difficult on the technology realize.
The purpose of this utility model realizes that in order to solve single face does not have the problem of load mould spot welding on the general point soldering equipment exactly, does not have load mould combined spot welding electrode and release a kind of single face.
The technical solution of the utility model is above electrode body and electrode tip socket, the mode of bottom electrode body and fixed cover socket, the axis that makes upper and lower electrode body and electrode tip is by the heart among the core pad on the insulation sleeve, make electric current around the insulating core pad, form the loop, thereby avoid the formation of load mould to be achieved.
Fig. 1 does not have load mould combined spot welding electrode schematic diagram for single face.
The diagram mark:
The 1-polar body 2-electrode tip that powers on
3-bottom electrode body 4-fixed cover
5-insulation sleeve 6-core pad
The 7-workpiece
Be described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the polar body that powers on (1) adopts red copper T4 to make, and has favorable conductive and thermal diffusivity.In the below socket material of the polar body that powers on (1) is that the cartridge of chromium zirconium copper is the electrode tip (2) of sphere.Socketing method adopts taper fit, the centering of be convenient to power on polar body (1) and electrode tip (2) and change electrode tip (2).Bottom electrode body (3) also adopts red copper T4 to make, and socket material is the fixed cover (4) of chromium zirconium copper on it, and insulation sleeve (5) adopts the insulation heat resistant rubber to make, and places in the middle of the fixed cover (4).The core pad made from 45# quenched and tempered steel (6) then places on the insulation sleeve (5), core pad (6) and fixed cover (4) insulation.
When using the utility model, electric current through electrode tip (2), workpiece (7), fixed cover (4), passes to bottom electrode body (3) by the polar body that powers on (1).Owing between core pad (6) and the fixed cover (4), be equipped with insulation sleeve (5), and be centered in electrode tip (2) below, make on the plane of bottom, weldering nuclear district, can not produce load mould.Simultaneously, electrode tip (2) cartridge adopts dome shape, impression is not evenly had splash.
Advantage of the present utility model:
1, cost reduces, and is applicable to the general point soldering equipment;
2, electrode tip (2) adopts taper fit, and is good to neutrality, changes conveniently;
3, quality of welding spot is good, has exempted polishing, the preceding finishing process of chromium plating, and presentation quality also is improved.
Claims (3)
1, a kind of single face does not have load mould combined spot welding electrode, mainly by the polar body that powers on (1), bottom electrode body (3) constitutes, it is characterized in that going up socket electrode tip (2) at the polar body that powers on (1), on bottom electrode body (3), be equipped with fixed cover (4), in the middle of the fixed cover (4), be equipped with core pad (6) by insulation sleeve (5), insulation between fixed cover (4) and the core pad (6), the axis of upper and lower electrode body (1), (3) and electrode tip (2) is by the center of core pad (6).
2, a kind of single face as claimed in claim 1 does not have load mould combined spot welding electrode, it is characterized in that adopting taper fit between electrode tip (2) and the polar body that powers on (1).
3, a kind of single face as claimed in claim 1 does not have load mould combined spot welding electrode, it is characterized in that the cartridge of electrode tip (2) is dome shape.
