Description

A kind of welding equipment of multi-functional threaded fastener

Art

This utility model is related to a kind of welding equipment of threaded fastener.

Background technology

Threaded fastener be welded on the application in manufacture field widely, such as automobile, motorcycle, electric bicycle, work Journey machinery, communication apparatus, high ferro train, aircraft etc..The welding manner of conventional threaded fasteners is resistance projection-welding, and welding equipment is adopted With resistance spot weld (being also resistance projection-welding machine).This welding manner needs to process the welding ends of threaded fastener before welding Become salient point, will have the threaded fastener of salient point and other metal plate parts welding.Because the thermal source of this kind of welding manner is resistance Heat, therefore referred to as resistance projection-welding.Why have salient point, be in order to when welding by current convergence to improve the intensity of electric energy, no Then, welding would become hard to realize.In order to realize good welding effect, resistance projection-welding to the size of salient point, highly, quantity has very High requirement, and on same threaded fastener, the size of salient point, height also will be consistent.Moreover the screw thread for welding The specification of securing member is not very big, and majority, between M6-M14, processes 3-4 salient point, no on this little metal object Only very high to the manufacture requirements of processing technique and processing mold, also add manufacturing process, extend manufacturing time, screw threads for fastening Salient point on part also makes the material of manufacture increase.Although a unremarkable salient point, improve the manufacture of threaded fastener Cost.

Because threaded fastener is welded by the way of resistance projection-welding, therefore need to be welded with this equipment of resistance spot weld Connect.Resistance welder is generally divided into power supply, electrode, compression system, cooling system and control system composition.Power supply is to provide for welding The electric energy of sufficient intensity.Electrode is the welding mechanism of welding machine, is divided into upper and lower electrode, upper and lower electrode by threaded fastener with therewith The sheet metal component of welding passes through pressing mechanism (cylinder) and compresses, and electric current is conducted to threaded fastener and sheet metal component by electrode.Screw thread Resistance heat is produced by the gold of the salient point on threaded fastener and sheet metal component and bump contacts position after securing member and sheet metal component energising Belong to and be heated to welding temperature.At this moment pressing mechanism passes through electrode by pressure conduction to threaded fastener and sheet metal component, by high temperature Metal compaction position one end time complete to weld.The squeeze time of welding process, weld interval, holds time, when stopping Between and welding current etc. be controlled by control system.The effect of cooling system is exactly the temperature producing when reducing electrode welding Degree.

Connect threaded fastener with resistance spot welding machine, because its welding efficiency is high, simple operation and other advantages, extensively each at present Associated production producer is used.But its shortcoming is it is also obvious that be especially embodied in the following aspects：The cooling system of resistance spot weld System increased equipment purchase cost and use cost.Electrode needs to process the passage of cooling water, and cooling water is liquid, easily leaks outside, The difficulty of electrode machining is high.Electrode needs from high conductivity, low resistive metal, and price is high, and generally this kind of metal hardness is relatively Difference, easily weares and teares, and replacement frequency is high.Need during welding to apply very high precompression and upset force, easily operator is damaged. It is only suitable for welding low-carbon steel metal it is impossible to the welding more preferable metal of mechanical property such as middle, high-carbon, the metal relatively low to resistivity Welding as aluminum, magnesium etc. is more difficult, can not carry out the welding between dissimilar metal.Thin plate can only be welded, the thickness to more than 5mm Plate weld is poor.Due to needing to apply precompression and upset force to workpiece during welding, upper and lower electrode is necessary for perpendicular to workpiece Solder side, weld U-shaped sheet metal component when, the threaded fastener of bottom can only be welded, if welding threaded fastener U-shaped The both sides of sheet metal component, no matter threaded fastener is in inner side or outside, all cannot be carried out welding.This characteristic pair of resistance projection-welding The welding effect of pipe part especially hollow pipe is also bad.In addition this kind of plant capacity of resistance spot welding is big, unfavorable and electrical network Balance movement.

Moreover, electric resistance welding is used for the welding of threaded fastener, and weld strength is unstable, same equipment, with for the moment Between weld same product.The torsion of inspection after welding threaded fastener, the fluctuation range of torque value is also very big.Torsion is big much Exceed the requirement of threaded fastener weld strength, the threaded fastener that leads to of difference comes off, and causes to do over again, increased and produce into This, waste manpower and materials.Run into product structure complicated, the number of parts of assembling is many, such as find that in auto assembly screw thread is tight Firmware comes off, and not only affects the assembling progress of whole piece automobile assembly line.Because body structure complexity is it is possible to lead to screw threads for fastening Part drops and cannot take out inside vehicle body, and this situation is done over again just highly difficult, and vehicle body can only be scrapped.Utility model patent《A kind of Prevent welding slag from penetrating into the weld jig mechanism of nut bore》, patent No. CN20122066608750, the inside just refer to adopt resistance Projection welding nut, but nut-welding insufficient strength, also need to carry out consumable electrode active gasess with resistance spot welding machine again after being connect The thing of shielded arc welding (also referred to as carbon dioxide gas arc welding, hereinafter referred to as MAG weld) reinforcement of weld.In reality produces, Come off after resistance projection-welding welding threaded fastener this situation, and each manufacturer can run into, the simply height of probability of happening Different.The generation that runs into that customer requirement is strict or threaded fastener postwelding comes off than more frequently it is necessary to MAG weld into Pedestrian's work reinforcement of weld.Originally only needed to the threaded fastener through once welding, but secondary welding to be carried out, not only produces into Originally it is doubled, the production cycle similarly extends one times.

Patent《Nut-welding special welding gun and its process of welding》, patent No. CN2005100158849, this patent Fundamentals of Welding be to be welded using electric capacity discharge mode.Specifically striking is carried out by the striking salient point of welded nut, in wink Between arcing state under, the welding procedure on welded nut surface and welded piece local melting belongs to spiral shell in welding classification The category of post weldering.This invention clamps welded nut, then the in the hole positioning table of nut top being inserted mother metal by special welding gun Welded.The method, due to being welded using welding gun, is compared then more flexible with resistance spot weld, but the profile chi due to welding gun Very little too big, run into the narrow and small U-shaped sheet metal component of inside dimensions, and threaded fastener need to be welded on the situation of U-shaped sheet metal component medial wall, This welding manner is just helpless.Furthermore this welding method will on nut locating and machining platform, the welding position of nut Also to there is striking salient point, the processing technology ratio resistance projection welding of nut is more complicated.Also has the method to threaded fastener and mother metal Phosphorus content also have strict demand, be usually no more than 0.2%, otherwise weldability can reduce, easily cause threaded fastener and take off in a large number Fall.During welding gun welded nut, for ensureing the perpendicularity of nut and mother metal, operator during welding, is needed to position 3 of welding gun front end Post is all adjacent to mother metal.Due to being operated using artificial, efficiency is low and effect it is difficult to ensure that, operator somewhat neglects, and cannot protect 3 locating dowels of card are all adjacent to mother metal completely.This situation is even more serious in welding screw, because the length of stud is nut Several times even more than ten times, in the case that skew angle is consistent, length is longer, and the deviation on top is bigger.

Patent《A kind of sheet material and the quick positioning tool of nut-welding》, the patent No. 2013207956002, this patent maximum Advantage be exactly with《A kind of weld jig mechanism preventing welding slag from penetrating into nut bore》Compare and increased nut clamping device.Use MAG Weldering or non consumable arc welding electrode Heliarc welding (also referred to as argon arc welding, abbreviation TIG weldering once) welding are not result on nut Stick up, nut is posted with sheet material, seamless, perpendicularity is guaranteed.Because if not compressing to nut, according to existing Welding method, first weld a bit, solder joint (refers to weld seam, because of weld seam only one of which round dot size, therefore referred to as solder joint, the weldering of this paper Point refers both to weld seam) shrink in cooling, nut leads to the opposite side of nut solder joint in the case that other directions do not have restraining forceies Upwarp.《A kind of sheet material and the quick positioning tool of nut-welding》Solve such difficult problem very well, grip device is in clamp nut Also protect the screw thread of nut interior, the effect of welding slag preventing is also more preferable simultaneously.Sentenced according to this patent specification and Figure of description Disconnected, this frock should be hand-held.Therefore during operation, needing a human hand held frock, sheet material and nut are put into frock corresponding positions by another people Put, just can be welded after sheet material is all fixed with nut.And the hold down gag of nut needs manual operation, efficiency is low, and passes Although the resistance spot weld equipment of system is complicated, it is power clamp nut using compressed gas, high degree of automation, collection sheet material, Nut positions and is welded in one, and all processes only need one man operation, and integrated cost is compared instead than this hand-held positioning tool And can be much lower.This invention is simply used as positioning during welding, has no welding function.Sheet material positioning element, nut positions Part, on a centrage, such as runs into and needs on the side wall of U-shaped sheet metal component to weld this situation of threaded fastener, then cannot determine Position and welding.The taper of taper and sheet material positioning Xiao's head that nut only relies on pull bar plunger is positioned, and reliability is poor.

Patent《A kind of welding equipment for manufacturing nutplate》, patent No. CN2011201469988, welding equipment in this Increased nut, the automatic clamping of sheet material and conveyer device respectively on the basis of traditional resistor mash welder, automaticity with Traditional resistor spot welding is compared and is further improved.Patent《Nut welding machine》, patent No. CN2013203736234, be The resistance spot weld of one double.Patent《Special welding machine for nut of anti-theft door》, patent No. CN2008201644129, then be one The resistance spot weld of individual multistation.Patent《Nut pinch welder》, patent No. CN2009201265837, this invention improves nut weld The motility connecing.Above-mentioned four patents have his own strong points, but its Fundamentals of Welding is all resistance projection-welding, correspondingly, resistance projection-welding lack Point also cannot overcome in this four patents.

In sum, the welding manner currently used for threaded fastener has two big class one kind is resistance projection-welding, and another kind is Arc-welding.The thermal source of electric resistance welding is resistance heat, and electrode collection welds, compresses, being positioned one, and structure is simple.But electrode needs to cool down, Need during welding to apply the precompression of sufficient intensity and upset force, can only welding low-carbon steel, threaded fastener welding position needs Process the shortcomings of salient point, welding stability difference also very important.Arc-welding is also classified into two kinds to the welding of threaded fastener, a kind of It is to be welded with MAG weldering, TIG weldering etc., another kind is arc stud welding.The advantage of TIG weldering is to splash less, does not almost have, therefore welds It is not required to when connecing using anti-splash measure.Need easy positioning tool during welding nut is positioned, if do not done frock If will by nut process a positioning boss similar to above《Nut-welding special welding gun and its technique side of welding Method》In nut positioning table, during welding, positioning boss is put into the corresponding in the hole of metal plate parts, completes the positioning to nut, Nut typically welds 2-4 point, artificial welding according to the size of specification, and any welds welds another point again, once welds a bit, a spiral shell Mother will weld through 2-4 time, and solder joint is evenly distributed on around nut.Due to there being filler metal, therefore solder joint welds than TIG for MAG weldering Full, there is no the defect of undercut yet.In addition with metal inert gas arc welding (hereinafter referred to as MIG weldering), this kind of weldering Connect and be similar to it is simply that protective gas is different with MAG weldering.Arc welding threaded fastener, in addition to ensureing nut accurate positioning, also Need nut is compressed, otherwise when welding at first point because nut inequality of being heated leads to nut can not fit with panel beating, cause Nut crooked (if bolt is then more serious).Patent《A kind of sheet material and the quick positioning tool of nut-welding》Although there being compression work( Can, but shortcoming is also apparent from.It is exactly finally arc stud welding, the welding gun of arc stud welding is operated using artificial, and stability is poor.

Although the mode of welding threaded fastener is a lot, such as resistance projection-welding, MAG weldering, TIG weldering, MIG weldering, arc stud welding etc., But run into the special sheet metal component of some shapes, the welding of threaded fastener is also highly difficult.The U-shaped sheet metal component side arm that picture is said above Threaded fastener is welded in inner side and outer side, and both of these case resistance projection-welding all can not weld.Arc stud welding can only weld side-wall outer side Threaded fastener, then can not in inner side.Although MAG weldering, TIG weldering, MIG weldering can be welded, because inner space is narrow and small, screw thread is tight The positioning of firmware and compression are all highly difficult.During such as welded nut, with a matching bolt, nut driving can only be existed On sheet metal component, again bolt is back-outed after welding.It is extremely inefficient that this mode welds threaded fastener.Substitution method is exactly to use Blind nut, matching is hand riveter.The mode of this riveting carrys out attaching nut, and production efficiency increases, but riveting The manufacturing process of nut is complicated, high cost, and needs the instrument hand riveter of extra purchase riveting nut.

Content of the invention

This utility model passes through to change the different sources of welding current and change matched welding gun, can be on same equipment Realize the welding to threaded fastener for the welding manner such as MAG weldering, TIG weldering, MIG weldering, arc stud welding, MIG soldering.And for different outer The workpiece of the shape detent mechanism different with the design of different types of threaded fastener, clamp system and welding gun form.Can carry out Various complex profile sheet metal components, the welding of particularly U-shaped sheet metal component side wall and threaded fastener；And various pipe fitting (cross section For circular or polygon, hollow or solid) welding with threaded fastener.It also is adapted for various metal materials, dissimilar metal The welding of even foreign material and threaded fastener.This utility model has and threaded fastener and workpiece is positioned simultaneously With the dual-use function of welding, and an equipment can install many welding guns and be welded, with traditional arc welding threaded fastener Compare, there is welding efficiency height, the good advantage of welding quality.

Welding method of the present utility model and equipment solve its technical problem and be employed technical scheme comprise that：Body, welding Mechanism, Power Component, clamping device, hold-down mechanism, detent mechanism, arc light baffle plate assembly, control system and illuminating lamp, counting Some other miscellaneous function parts such as device form the welding equipment of complete set.Body is welding mechanism, Power Component, clamping machine Structure, hold-down mechanism, the carrier of detent mechanism, arc light baffle plate assembly and control system.Power Component can use pneumatic cylinder, hydraulic pressure Cylinder or motor provide power.Welding mechanism is divided into MAG welding machine, tig arc welding machine, MIG welding machine, stud welding machine, if necessary Welding high-carbon steel, steel alloy, dissimilar metal or foreign material, can also use MIG soldering welding machine.Welding mechanism executes welding , by control system, welding mechanism is arranged on body for the switch of task, power output of Power Component etc., can place in body One or more welding mechanism is it is also possible to place polytype welding mechanism it is possible to change at any time as needed not simultaneously The welding mechanism of same type.Welding gun on welding mechanism is changed to clipping by hand held, is fixed on the clamping device of equipment, former Then go up a welding machine and join a welding gun but it is also possible to a welding mechanism accompanies multiple stage wire feeder and many welding guns, and welding gun can Arbitrarily to change.That is a threaded fastener can be welded using many clipping welding guns simultaneously, or even a screw thread On securing member can simultaneously using MAG weldering, TIG weldering, MIG weldering and MIG soldering welded (if necessary).Screw threads for fastening Part is completed by detent mechanism with the positioning of workpiece, and threaded fastener is completed by hold-down mechanism with the compression of workpiece, in particular cases, Hold-down mechanism also has the function of positioning concurrently.The positioning mode of threaded fastener and workpiece include compound positioning, location-independent and Integrated positioning that both modes combine etc..Compound positioning mode is exactly threaded fastener and workpiece to be positioned simultaneously, This positioning mode is suitable for workpiece weld the situation in hole, and it is fixed that nut is carried out to workpiece typically by the way of alignment pin simultaneously Position, that is, alignment pin is step, and the big part of alignment pin diameter, the screwed hole insertion positioning of nut are inserted in the hole of workpiece weld The little part of pin diameter, is equipped with locating surface in addition again and is positioned, and is combined the workpiece positioning and alignment pin all using same fixed Position pin and locating surface positioning.The positioning of bolt is typically positioned to workpiece by the way of location hole and locating surface simultaneously, that is, Bolt is inserted into positioning in the hole through after the hole of workpiece weld, is equipped with locating surface in addition again and is positioned.Location-independent mode It is exactly respectively threaded fastener and workpiece to be positioned, threaded fastener and workpiece have independent detent mechanism to carry out determining respectively Position, is not related between the detent mechanism of threaded fastener and the detent mechanism of workpiece.Alignment pin and locating surface are only to nut Positioned, location hole and locating surface only position to bolt, and limited post positions to the side of workpiece and profile, (inclination) Positioning vertical pole (eccentric positioning tube) positions to the face of workpiece, alignment pin to the hole of workpiece (include the hole of weld and other Local hole) positioned.Integrated positioning is exactly that the compound mode being combined with location-independent that positions is positioned, and is used for multiple Close in the case that positioning can not position to workpiece completely and be aided with the mode of location-independent again, that is, with alignment pin, positioning While hole, locating surface position to threaded fastener and workpiece, reuse limited post, (bias is fixed for (inclination) positioning vertical pole Position cylinder) and alignment pin workpiece is positioned.Mode it can in addition contain be irradiated with light beam is positioned, and will launch light beam Light source is fixed on equipment, and the position welding threaded fastener in workpiece marks, and the luminous point that light beam is radiated on workpiece is For the welding position of threaded fastener, when luminous point is overlapped with the labelling on workpiece, that is, complete the positioning to workpiece.Ordinary circumstance Lower nut is positioned with screwed hole, and special circumstances lower nut can also be using profile positioning, that is, location hole is positioned. In the case that bolt has hole, bolt can also be positioned with alignment pin.Alignment pin and location hole are stationary type vertical in ground Face (horizontal plane) or rotary and with ground (horizontal plane) at an angle.Screw bolt and nut can be positioned at workpiece Top, lower section, front, right, any direction such as left and right.No matter being the positioning of threaded fastener or determining of workpiece Position just can make the position of object have uniqueness it is necessary to carry out limiting to its front, back, left, right, up, down six direction, that is, fixed Position.Alignment pin, location hole can limit four direction, and limited post, (inclination) positioning vertical pole (eccentric positioning tube), locating surface can limit Both direction.

In order to avoid the injury to operator's eyes and facial skin for the arc light in welding, this utility model is also equipped with arc light Baffle plate.Before welding, the welding parameters such as electric current, voltage, wire feed rate, gas flow are set on welding machine.By hold-down mechanism and Clipping welding gun moves down, and regulation hold-down mechanism is forward and backward, the position of upper and lower all directions is so as to can collet threaded securing member and workpiece (sheet metal component or pipe fitting)；Regulate distance and the angle of welding gun on clamping device and weld again.Mix up rear Power Component Drive compression

Mechanism and clamping device move up reset, and equipment is in state to be welded.During formal welding, screw thread is tight Firmware and workpiece are put into detent mechanism and are positioned.Then starting device, Power Component drives hold-down mechanism and welding gun to moving down Dynamic, while collet threaded securing member and workpiece, welding mechanism is opened, and welding mechanism starts the weldering to threaded fastener and workpiece The place of connecing is welded, and when with stud welding machine welding threaded fastener, a stud welding gun welds a threaded fastener.When During with MAG weldering, TIG weldering, MIG weldering and MIG soldering welder threaded fastener, a welding gun is between threaded fastener and workpiece Weld a solder joint.Operator can weld several solder joints as needed, need only install the welding gun of equal number.Generally feelings 2-4 clipping welding gun is installed under condition and just can meet needs.Welding continues for some time (0.1-30 second) and welds afterwards and terminate, and now moves Power assembly drives hold-down mechanism and welding gun to reset, and then the product welding is taken out by operator, and whole welding process completes, subsequently Carry out the welding of next threaded fastener, such circulate operation.The operation such as the compression of each functional unit, welding, reset above Content is controlled by the control system of equipment, and operator only needs piece installing starting device pickup, and whole process one people just can Complete, and simple to operate, it is not required to carry out professional training, slightly training just can operate.Operator can be according to the product of unlike material Product select different welding manners.As the materials such as welding low-carbon steel, medium carbon steel and rustless steel can select MAG to weld；Welding low-carbon The materials such as steel, rustless steel, aluminum, magnesium can select TIG weldering or MIG weldering；Welding high-carbon steel, steel alloy, non-ferrous metal, xenogenesis gold Belong to even foreign material and can select MIG soldering；If selection arc stud welding, can be with welding low-carbon steel and rustless steel.Work as spiral shell The welding job of stricture of vagina securing member is not too many, equipment temporarily leave unused when, then can on equipment welding mechanism (MAG welding machine, Tig arc welding machine, MIG welding machine, MIG soldering welding machine) remove, welding gun is replaced with and commonly manually operates welding gun, you can often to carry out The human weld of rule, if being replaced with robotic gun, mixes welding robot it is possible to carry out robot automation's welding. Carry out arc stud welding if desired in the heavy parts that bulky, personnel cannot move or machinery equipment, then can be stud The clipping welding gun of weldering is replaced with existing common hand-held welding gun, plays its advantage that is flexible, being not required to move welding workpiece.This reality With new threaded fastener without processing salient point, and threaded fastener can be replaced to be connected with the staking of workpiece.It is a kind of real A tractor serves several purposes, the threaded fastener welding equipment of one-machine-multi-function.

MAG weldering, TIG weldering, MIG weldering, the difference of MIG these four welding manners of soldering are, the protective gas of MAG weldering It is consumable electrode welding wire for active gasess, electrode form；The protective gas of TIG weldering is noble gases, and electrode form is not melt Change pole tungsten electrode；The protective gas of MIG weldering is noble gases, and electrode form is consumable electrode welding wire；The protection of MIG soldering Gas is noble gases, and electrode form is consumable electrode solder.MAG weldering, MIG weldering are to rely on electric arc heat fusing mother metal and filling Metal；TIG weldering is to rely on electric arc heat fusing mother metal, does not have filler metal；MIG soldering is to rely on electric arc heat fusing solder, mother metal Non-fusible.Although above-mentioned four kinds of welding manners are slightly different, the form of welding gun is essentially the same, as long as adopting corresponding bonding machine Structure, and existing welding gun is slightly improved, corresponding welding gun is installed on clamping device and can achieve.Therefore technique scheme can Realize MAG weldering, TIG weldering, MIG weldering, the welding to threaded fastener for the MIG soldering.

The beneficial effects of the utility model are：The welding manner of this threaded fastener of existing resistance projection-welding, is pressure One kind of weldering, needs the pressure applying to be up to 3000N-10000N during welding.And this equipment adopts MAG weldering, TIG to weld, MIG welds, The welding manner such as arc stud welding and MIG soldering, belongs to arc welding in welds types.Welding itself does not need pressure, is In fixation, collet threaded securing member and workpiece, prevent the purpose ability of welding deformation from applying suitable pressure in welding, but this Power be far from resistance projection-welding pressure big, only 1/10th about of electric resistance welding pressure.Because welding pressure is little, thus without Operator is damaged.The workpiece more special to some profiles and welding position is as in the wall of U-shaped sheet metal component side Side is threadably secured the welding of part, due to employing the welding manner of special detent mechanism and arc-welding, also can easily realize, Thus avoiding fixing threaded fastener (high cost of staking threaded fastener, efficiency are low) by the way of staking.This practicality is new Type is to rely on arc heat to melt to realize welding by threaded fastener and workpiece, and threaded fastener does not need to process salient point, structure Simply.Threaded fastener and tubing (cross section of tubing is circular or polygon, and tubing is internally hollow or solid) Welding, this utility model also has obvious advantage.Weld as (hollow or solid) with pipe, threaded fastener is connect with pipe Contacting surface only has a line, and traditional resistance projection-welding requires the salient point of threaded fastener need to contact with pipe, and otherwise welding just cannot Realize.That is threaded fastener and the position degree of pipe fitting have high demands, operator's bad assurance during welding.If tubing is (empty Heart pipe) tube wall too thin, the pressure of resistance projection-welding will by pipe fitting compressive strain, and weld strength also can reduce will during welding Pressure needed for light wall pipe be collapsed leads to weld can not meet.If the solid tubes that tube wall is too thick or caliber is too big, will Cause threaded fastener to mismatch with workpiece, so that welding difficulty increase is followed on slab and carry out one reason of resistance projection-welding. Cross section is polygonal tubing, and the side due to this kind of tubing is all plane, and during welding, threaded fastener and tubing position degree will Ask and on the contrary reduce much.But if will be welded on tubing seamed edge, then occur with weld on pipe problem. This utility model adopts arc welding principle, is not required to want powerful pressure during welding, also not against resistance heat and acceptable when welding Add filler metal.Entirely different with the Fundamentals of Welding of resistance projection-welding, when threaded fastener is welded with tubing, either solid Tubing, hollow tubing, thick tubing, thin tubing, is circular tubing or polygonal tubing regardless of cross section Can easily realize welding.In terms of welding material, electric resistance welding can only welding low-carbon steel or rustless steel, and this equipment can not only Welding low-carbon steel and rustless steel are moreover it is possible to weld medium and high carbon steel, steel alloy non-ferrous metal, dissimilar metal even foreign material.

Traditional MAG weldering, TIG are welded, MIG welds, the method for MIG Welding threaded fastener, no pressed positioning mechanism, and Using human weld.Human weld once can only weld a bit, and a threaded fastener typically need to weld 2-4 point, then also Need welding 2-4 time, the welding efficiency which results in traditional arc welding threaded fastener is very low.Human weld is to operation The level of skill requirement of person is also very high, needs the training through specialty could be competent at.Threaded fastener is welded on workpiece, needs Threaded fastener and workpiece are positioned, simplest method is exactly to take self-align mode.It is exactly in threaded fastener One positioning boss of upper processing, the shape of positioning boss is coordinated with the hole on workpiece with size, and during welding, threaded fastener is convex Platform prevents the in the hole into workpiece, is then being welded.But threaded fastener is not constrained by external force, and once can only weld One solder joint, this is resulted in the uneven one end easily causing threaded fastener that is heated and upwarps it is impossible to be adjacent to workpiece, due to not having Protective measure, screw thread also can be stained with spatter.Mentioned above《A kind of weld jig machine preventing welding slag from penetrating into nut bore Structure》, prevent by anti-splashing alignment pin welding slag from entering in nut, but the material of this alignment pin do not illustrated, with exhausted Edge material result is best.Though with effect, this anti-splashing alignment pin and the spiral shell that also can play pre- welding slag preventing if metal material Female thread contact can produce contact resistance, the screw thread in high temperature meeting scaling loss nut that contact resistance produces.Even if passing over anti- The problem of materials of splashing alignment pin, this patent also has a lot of defects.There is no hold down gag first, convex if not using resistance in advance Nut is welded by weldering, and welding back nut will upwarp, and nut cannot ensure with the perpendicularity of sheet metal component.Threaded fastener is divided into Nuts and bolt (or stud), only the splashing to nut has fine preventive effect to this patent, inapplicable to bolt.If met Welded to tubing with nut, this patent does not have corresponding technical scheme yet.《A kind of sheet material and nut-welding quickly position work Dress》, this patent carrys out clamp nut using nut positioning element, and the problem that nut upwarps has obtained good solution.But also only fit Close the welding of nut and sheet material, if the welding of other forms, such as bolt and metal sheet carry out welding, the weldering of nut and tubing Connect or bolt is all inapplicable with the welding of tubing.And in practical operation, needing a human hand held positioning tool, another people enters The positioning work of andante material and nut, two people's cooperatings just can complete, and is also to need human weld after the completion of positioning.This positioning Frock not only operates that number is many, and efficiency is also very low, also high to the skill set requirements of welder.No matter being《One kind prevents welding slag from oozing Enter the weld jig mechanism of nut bore》, or《A kind of sheet material and the quick positioning tool of nut-welding》, a kind of substantially simply work Clamps, function only as positioning and the protective action of threaded fastener, do not have the function of welding, the welding of threaded fastener Also need to welding equipment to complete.Although traditional arc stud welding can once complete in welding screw or nut, workman exists Not only stud or nut are welded on the position that workpiece specifies exactly during welding, simultaneously threaded fastener also to be ensured With the perpendicularity of workpiece, which results in that traditional arc stud welding positioning precision is poor, perpendicularity is unstable, and efficiency is not also high.This practicality Novel pin separately designs different detent mechanisms, clamp system and welding gun, energy to different workpiece and different threaded fasteners Realize the sheet metal component (including U-shaped sheet metal component) of variously-shaped and thickness, variously-shaped and thickness tubing respectively with all kinds Threaded fastener welding.This welding equipment is located on ground, is not required to manpower and helps, hold-down mechanism is carried by Power Component Not only save manpower for power, ensureing the laminating degree that threaded fastener is with workpiece, perpendicularity and preventing the damage screw thread that splashes While efficiency also higher.The contact portion of detent mechanism and threaded fastener screw thread is using high-strength insulating material or to setting Carry out insulation processing with the position of thread contact in standby, prevent the damage to screw thread for the contact resistance.Welding equipment is in compression spiral shell Welded while stricture of vagina securing member, high degree of automation.Achieved by many clipping welding guns are installed on welding equipment That welds once completes, and welding efficiency is high；The work such as the positioning of threaded fastener and workpiece, welding one people can complete, welding Front need set every welding parameter, and adjust detent mechanism, hold-down mechanism, the position of clipping welding gun just can easily be welded Connect, low to the skill set requirements of operator, save human cost.The welding gun of arc stud welding be changed to by traditional hand-held clipping, It is fixed on the clamping device of equipment, driven by Power Component.Ensure that during arc stud welding that nut is fitted closely and spiral shell with workpiece Post is vertical with workpiece；It is not required to during welding will manually operate welding gun, efficiency is also higher.
