Description
Technical field
This utility model is related to field of mechanical technique, specifically a kind of projection welding electrode for being provided with traveling nut.
Background technology
In current automobile and the design of household electrical appliances hardware, for improve production efficiency, start to adopt metal parts
Directly projection welding is on another part, the method for once forming 2,3 or 4 solder joints.Such design reduces part life
Operation is produced, number of parts is reduced, welding energy consumption is reduced, more conducively environmental protection, while reducing production cost.
But such structure design, very high for the requirement of projection welding, traditional projection welding electrode cannot Reliable guarantee 2
Individual, the formation weld nugget that 3 or 4 salient point energy are stable, welding process is affected and unreliable by export license.
Accordingly, it would be desirable to be improved to traditional electrode, a kind of projection welding electrode for being provided with traveling nut is designed, to solve welding
The reliability of process, the ease for maintenance of frock.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of projection welding electricity for being provided with traveling nut
Pole, to solve the reliability of welding process, the ease for maintenance of frock.
In order to achieve the above object, this utility model is a kind of projection welding electrode for being provided with traveling nut, including electrode body, convex
Type electrode, alignment pin, insulation sleeve, insulation board, it is characterised in that：2 male electrodes, 2 male electrodes are fixed with electrode body
Middle part is provided with convex end face, and convex end face withstands traveling nut, and 2 male electrodes are fixed in electrode body using screw, convex
The side of electrode is provided with bolt, and between the end face and male electrode of bolt insulation sleeve, location-plate and insulation board are provided with, electrode body
Middle part is provided with groove, and alignment pin is provided with groove, and another insulation sleeve is provided between alignment pin and electrode body.
2 described male electrodes are arranged symmetrically in electrode body.
Described location-plate is set between insulation sleeve and insulation board.
The upper end of described alignment pin is provided with positioning sleeve.
This utility model compared with the existing technology, devises the projection welding electrode structure for being provided with traveling nut, after solving projection welding
Structural reliability, improve the qualification rate of production, improve welding quality, efficiency and stability of the production process.This reality
Only need to complete to safeguard by changing male electrode with new, both improve maintainability, also reduce cost.Additionally, effectively protecting
Welding quality is demonstrate,proved, also can suitably reduce welding heat energy input, energy saving.This utility model can be widely applied to metal stamping
Part projection-welding structure.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view of the present utility model.
Referring to Fig. 1 and Fig. 2,1 is electrode body；2 is male electrode；3 is insulation sleeve；4 is location-plate；5 is insulation board；6 are
Alignment pin；7 is another insulation sleeve；8 is positioning sleeve；9 is traveling nut；10 is weldment；11 is screw.
Specific embodiment
This utility model is described further in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, this utility model is a kind of projection welding electrode for being provided with traveling nut, including electrode body, convex electricity
Pole, alignment pin, insulation sleeve, insulation board.The middle part of 2 male electrodes, 2,2 male electrodes 2 is fixed with electrode body 1 and is provided with convex
End face, convex end face withstands traveling nut 9.2 male electrodes 2 are fixed in electrode body 1 using screw 11, male electrode 2
Side is provided with bolt, and insulation sleeve 3, location-plate 4 and insulation board 5,4 sets of location-plate are provided between the end face and male electrode 2 of bolt
It is located between insulation sleeve 3 and insulation board 5.The middle part of electrode body 1 is provided with groove, and alignment pin 6, alignment pin 6 and electricity are provided with groove
Another insulation sleeve 7 is provided between polar body 1, the upper end of alignment pin 6 is provided with positioning sleeve 8.
In this utility model, 2 male electrodes 2 are arranged symmetrically in electrode body 1.
In this utility model, electrode withstands traveling nut 9 using split type by the convex end face of male electrode 2 so as to
It is positioned at solder joint.In addition whole part except weld conduction in addition to, also by the insulation board on electrode holder, insulation sleeve and weldering
Welding fixture is completely insulated, reduces and part conductive contact area, the electrode pressure at 2 solder joint positions when effectively increasing projection welding,
Electric current density, reduces current distributing, and 2 solder joints are obtained the nugget of stable and consistent, so that welding quality is greatly improved.
Electrode adopts male electrode 2, safeguards that area is reduced to electrode end surface every time, and maintenance quality and efficiency are improved,
After male electrode 2 weares and teares, only male electrode 2 need to be changed, without the need for changing electrode body 1, electrode life is extended, so as to
Reduce welding cost.
