Description
Technical field
The present invention is used for welding gun field, more particularly to a kind of welding gun electrode arm cooling water pipe fixed structure.
Background technique
Resistance spot welding welding gun is mainly used during carbon fiber automobile body-in-white welding production.Resistance spot welding gun is mainly used for
Welded body plate.Entire vehicle body is that white body is combined by resistance spot welding welded blank, the shape of white body be by
It is designed according to the acceptance level in market and the update cycle is shorter.Body contour has to the aesthetic power flow changing in follow-up market
And change, it can just obtain achievement of sale in the market in this way.Therefore, car configuration will often change, then, due to
The variation of appearance and modeling, the plate welding position of white body part and plate shape can change.Due to now for
The weight of resistance spot-welding servo welding gun is more sensitive, and weight can determine in specific production process, the beat speed-raising of production.Cause
This, the horn that the horn in resistance spot-welding servo welding gun applied at present largely uses aluminum alloy material to manufacture.
Currently, welding gun carries out welding process when automobile body-in-white produces, welding gun is needed to welding position, electrode stem, electrode
It is cooling that cap carries out internal water cooling, and all conductive contact surfaces inside welding gun require to carry out water flowing cooling.Copper material can be
Internal directly punching is cooled down, but aluminum alloy materials cannot directly contact cooling water in the case where energization, because in water
Ion can under the action of electric current, with aluminum alloy materials generate electrochemical corrosion, and then influence aluminum alloy material performance, and
And horn belongs to high stress part, has to avoid the occurrence of corrosion phenomenon.There is the reason of because of Automobile Body Modeling again, can make
It is all very different at the horn size and shape of welding gun, not all copper electrode arm can process inner hole completely.This
The case where sample, causes in many cases, and cooling water needs to arrange that other cooling water water pipe carries out water flowing cooling, makes cooling water can
To reach electrode stem and electrode cap welding position.Early period is designed in white body automation welding and assembling production lines, is needed to whole cloth
The motion profile and equipment design pattern of office and robot carry out simulating, verifying, it is ensured that field device is before production, i.e.,
Analog field device situation and operating status, it is ensured that produce and complete in equipment, after scene is integrated, can satisfy actual
Claimed condition and productive temp.In design of Simulation, the horn of welding gun is all to need to protrude into equipment and white body workpiece
Middle carry out welding procedure.But because the cooling water pipe in addition arranged is will not to emulate to use in welding gun in design welding gun early period
It is shown in digital-to-analogue.Furthermore because cooling water pipe is polyurethane flame-proof hose.When live practical application, the movement of water pipe
Form and specific location are uncontrollable, and because of the adhesion of the dust impurities such as welding slag, the state of water pipe more can not be pre-
Meter control.
Because of the presence of above situation, will cause live cooling water pipe and bodywork or other equipment generate interference with
Winding, robot drive in resistance spot-welding servo welding gun motion process, it may appear that pullling and cutting, wearing to cooling water pipe.
Cutting or breaking for cooling water pipe will be caused when serious.And then the supply of cooling water is influenced, influence welding quality.And because
Largely to there is electrical component in field device, after cooling water water pipe is cut or is broken, cooling water can a large amount of splashes to setting
On standby, there is the very big equipment electric component that may cause to burn out.
Summary of the invention
In order to overcome the above cooling water water pipe motion state that can not emulate, field condition can not it is estimated with control the case where,
The present invention provides a kind of welding gun electrode arm cooling water pipe fixed structure, with compact-sized, does not influence horn size itself
The characteristics of with stress and water pipe fully controls within horn profile.
The technical solution adopted by the present invention to solve the technical problems is: a kind of welding gun electrode arm cooling water pipe fixed knot
