Description

A kind of Welding Method & Equipment of multi-functional threaded fastener

Art

The present invention relates to the Welding Method & Equipment of a kind of threaded fastener.

Background technology

The application being welded on manufacture field of threaded fastener 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 be processed by the welding ends of threaded fastener before welding Become salient point, the threaded fastener having salient point is welded with other metal plate parts.Owing to the thermal source of this kind of welding manner is resistance Heat, therefore referred to as resistance projection-welding.Why there is salient point, by current convergence when being to weld, in order 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 the size of salient point on same threaded fastener, the most also to keep consistent.Moreover the screw thread for welding The specification of securing member is not the most very big, most between M6-M14, processes 3-4 salient point, no on this little metal object Only the highest 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.

Owing to threaded fastener uses the mode of resistance projection-welding to weld, therefore need to weld 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 is compressed by pressing mechanism (cylinder), and electric current is conducted to threaded fastener and sheet metal component by electrode.Screw thread The resistance heat gold by the salient point on threaded fastener and sheet metal component with bump contacts position is produced after securing member and sheet metal component energising Belong to and be heated to welding temperature.At this moment pressing mechanism by electrode by pressure conduction to threaded fastener and sheet metal component, by high temperature Metal compaction one end, position time complete welding.The squeeze time of welding process, weld interval, holds time, when stopping Between and welding current etc. be controlled by control system.The temperature that the effect of cooling system produces when reducing electrode welding exactly Degree.

Connecing threaded fastener with resistance spot welding machine, because its welding efficiency is high, simple operation and other advantages, the most extensively by respectively 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 adds equipment purchase cost and use cost.Electrode needs the passage of processing cooling water, and cooling water is liquid, easily leaks outside, The difficulty of electrode machining is high.Electrode needs to select high conductivity, low resistive metal, and price is high, and usual this kind of metal hardness is relatively Difference, easily weares and teares, and replacement frequency is high.Need during welding to apply the highest precompression and upset force, easily operator is damaged. It is only suitable for welding low-carbon steel metal, it is impossible to the more preferable metals of mechanical property such as welding middle, high-carbon, the metal relatively low to resistivity Welding such as aluminum, magnesium etc. is more difficult, more can not carry out the welding between dissimilar metal.Thin plate can only be welded, the thickness to more than 5mm Plate weldability is poor.Needing during due to welding workpiece is applied precompression and upset force, upper and lower electrode is necessary for being perpendicular to workpiece Solder side, weld U-shaped sheet metal component time, can only weld bottom threaded fastener, 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 the most bad.Additionally this kind of plant capacity of resistance spot welding is big, unfavorable and electrical network Balance movement.

Moreover, electric resistance welding is 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 the biggest.Torsion is big far away Having exceeded the requirement of threaded fastener weld strength, the threaded fastener that causes of difference comes off, and causes and does over again, adds and produce into This, waste manpower and materials.Running into product structure complicated, the number of parts of assembling is many, and as found when auto assembly, screw thread is tight Firmware comes off, and not only affects the assembling progress of whole piece automobile assembly line.Owing to body structure is complicated, it is possible to cause screw threads for fastening Part drops and cannot take out inside vehicle body, and this situation is done over again the most highly difficult, and vehicle body can only be scrapped.Utility model patent is " a kind of Prevent welding slag from penetrating into the weld jig mechanism of nut bore ", patent No. CN20122066608750, the inside just refer to use resistance Projection welding nut, but nut-welding insufficient strength, also need to carry out consumable electrode active gases with resistance spot welding machine again after connecing The thing of shielded arc welding (also referred to as carbon dioxide gas arc welding, hereinafter referred to as MAG welds) reinforcement of weld.In reality produces, Come off after resistance projection-welding welding threaded fastener this situation, and each manufacturer can run into, simply the height of probability of happening Different.Run into that customer requirement is strict or threaded fastener postwelding comes off generation ratio more frequently, it is necessary to MAG weld into Pedestrian's work reinforcement of weld.Originally had only to the threaded fastener through once welding, secondary welding to be carried out, not only produced into Originally being doubled, the production cycle extends one times too.

Patent " nut-welding special welding gun and the process of welding thereof ", patent No. CN2005100158849, this patent Fundamentals of Welding be use electric capacity discharge mode weld.Specifically carried out striking, in wink by the striking salient point of welded nut Between arcing state under, by the welding procedure on welded nut surface Yu welded piece local melting, in welding classification, belong to spiral shell The category of post weldering.This invention clamps welded nut by special welding gun, then is inserted by the positioning table of nut top in the hole of mother metal Weld.The method is owing to using welding gun welding, with resistance spot weld is compared the most flexible, but due to the profile chi of welding gun Very little too big, run into the U-shaped sheet metal component that inside dimension is narrow and small, and threaded fastener need to be welded on the situation of U-shaped sheet metal component medial wall, This welding manner is the most helpless.Furthermore this welding method will on nut locating and machining platform, the welding position of nut Striking salient point to be had, the processing technology of nut is more complicated than resistance projection-welding.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, and easily causes threaded fastener and takes off in a large number Fall.During welding gun welded nut, for ensureing the perpendicularity of nut and mother metal, during welding, need operator by 3 location of welding gun front end Post is all adjacent to mother metal.Owing to using manual operation, efficiency is low and effect it is difficult to ensure that, operator somewhat neglects, and cannot protect Demonstrate,prove 3 locating dowels to be adjacent to mother metal all completely.This situation is even more serious when welding screw, because the length of stud is nut Several times even tens times, in the case of skew angle is consistent, length is the longest, and the deviation on top is the biggest.

Patent " a kind of sheet material and the quick positioning tool of nut-welding ", the patent No. 2013207956002, this patent maximum Advantage adds nut clamping device exactly compared with " a kind of weld jig mechanism preventing welding slag from penetrating into nut bore ".Use MAG Weldering or non consumable arc welding electrode Heliarc welding (also referred to as argon arc welding is once called for short TIG weldering) welding are not result on nut Sticking up, nut posts with sheet material, seamless, and perpendicularity is guaranteed.Because if nut not being compressed, according to existing Welding method, first weld a bit, solder joint (refer to weld seam, because of weld seam only one of which round dot size, therefore referred to as solder joint, weldering herein Point refers both to weld seam) shrink when cooling, nut causes the opposite side of nut solder joint in the case of other directions do not have restraining forces Upwarp." a kind of sheet material and the quick positioning tool of nut-welding " solves such difficult problem very well, and grip device is at clamp nut Also protecting the screw thread of nut interior, the effect of welding slag preventing is more preferable simultaneously.Sentence 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 weld after sheet material all fixes 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, using compressed gas is kinetic pressure jack panel, but automaticity is high, 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 location during welding, and welding function.Sheet material positioning element, nut positions Parts, on a centrage, need on the sidewall of U-shaped sheet metal component to weld this situation of threaded fastener as run into, then cannot determine Position and welding.The tapering of tapering and sheet material location Xiao's head that nut only relies on pull bar plunger positions, and reliability is poor.

Patent " a kind of welding equipment for manufacturing nutplate ", patent No. CN2011201469988, welding equipment in this On the basis of traditional resistor mash welder, add automatically clamping and the conveyer device of nut, sheet material respectively, automaticity with Traditional resistor means of spot welds 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 connect.Above-mentioned four patents have his own strong points, but its Fundamentals of Welding are all resistance projection-weldings, correspondingly, and lacking of resistance projection-welding Point also cannot overcome in these four patents.

In sum, the welding manner being currently used for threaded fastener has two big class one to be resistance projection-welding, and another kind is Arc-welding.The thermal source of electric resistance welding is resistance heat, and electrode collection welds, compresses, is positioned one, simple in construction.But electrode needs cooling, Need during welding to apply the precompression of sufficient intensity and upset force, can only welding low-carbon steel, threaded fastener welding position needs Processing salient point, the shortcomings such as welding stability is poor are the most very important.Arc-welding is also classified into two kinds to the welding of threaded fastener, Yi Zhongshi Welding with MAG weldering, TIG weldering etc., another kind is arc stud welding.The advantage of TIG weldering is to splash less, almost without, therefore weld Shi Buxu uses anti-splash measure.Need easy positioning tool during welding nut is positioned, as do not done frock Nut one positioning boss of processing will be similar to above " nut-welding special welding gun and the technique side of welding thereof by words Method " in nut positioning table, positioning boss is put in the corresponding hole of metal plate parts during welding, completes the location 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 be through 2-4 welding, and solder joint is evenly distributed on around nut.MAG welds owing to there being filler metal, and therefore solder joint welds than TIG 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 with MAG weldering is similar, it is simply that protective gas is different.Arc welding threaded fastener, in addition to ensureing nut accurate positioning, also Need nut is compressed, otherwise cause nut can not fit with panel beating when welding due to nut inequality of being heated at first, cause Nut crooked (if bolt is the most serious).Patent " a kind of sheet material and the quick positioning tool of nut-welding " is although there being compression merit Can, but shortcoming is also apparent from.Being exactly finally arc stud welding, the welding gun of arc stud welding uses manual operation, poor stability.

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 running into the sheet metal component that some shapes are special, the welding of threaded fastener is the most highly difficult.The U-shaped sheet metal component side arm that picture is said above Inner side and outer side welding threaded fastener, 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, owing to inner space is narrow and small, screw thread is tight Location and the compression of firmware are the most highly difficult.Such as during welded nut, with a bolt matched, 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 uses exactly Blind nut, match 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, and cost is high, and needs the extra instrument hand riveter buying riveting nut.

Summary of the invention

The present invention, by changing the different sources of welding current and changing matched welding gun, can realize on same equipment The welding manner welding to threaded fastener such as MAG weldering, TIG weldering, MIG weldering, arc stud welding, MIG soldering.And for different profiles Detent mechanism, clamp system and the welding gun form that workpiece is different with the design of different types of threaded fastener.Can carry out various Complex profile sheet metal component, the most U-shaped sheet metal component sidewall welds with threaded fastener；And various pipe fitting (cross section is circle Shape or polygon, hollow or solid) with the welding of threaded fastener.It also is adapted for various metal material, dissimilar metal even It is foreign material and the welding of threaded fastener.The present invention has and threaded fastener and workpiece is positioned and welded simultaneously Dual-use function, and an equipment can install many welding guns and weld, and compared with tradition arc welding threaded fastener, has Welding efficiency is high, the advantage that welding quality is good.

The welding method of the present invention and equipment solve the technical scheme is that body of its technical problem, welding mechanism, Power Component, clamping device, hold-down mechanism, detent mechanism, arc light baffle plate assembly, control system and illuminating lamp, enumerator etc. The welding equipment of some other miscellaneous function parts composition complete set.Body is welding mechanism, Power Component, clamping device, pressure Tight mechanism, detent mechanism, arc light baffle plate assembly and the carrier of control system.Power Component can use pneumatic cylinder, hydraulic cylinder or Person's motor provides power.Welding mechanism is divided into MAG welding machine, tig arc welding machine, MIG welding machine, arc stud welding welding machine, if needing welding High-carbon steel, steel alloy, dissimilar metal or foreign material, it is also possible to use MIG soldering welding machine.Welding mechanism performs weld task Switch, Power Component power output etc. by control system, welding mechanism is arranged on body, can place one in body Or multiple stage welding mechanism, it is also possible to place polytype welding mechanism, it is possible to change inhomogeneity the most at any time simultaneously The welding mechanism of type.Welding gun on welding mechanism is changed into clipping by hand held, is fixed on the clamping device of equipment, in principle A welding gun joined by one welding machine but it also may a welding mechanism accompanies multiple stage wire feeder and many welding guns, and welding gun can be with Meaning changes.That is a threaded fastener can use many clipping welding guns to weld simultaneously, even one screw threads for fastening Can use on part simultaneously MAG weldering, TIG weldering, MIG weldering and MIG soldering carry out welding (if necessary).Threaded fastener with The location of workpiece is completed by detent mechanism, and threaded fastener is completed by hold-down mechanism with the compression of workpiece, in particular cases, compresses Mechanism also has the function of location concurrently.The location mode of threaded fastener and workpiece include compound location, location-independent and this two The integrated positioning etc. that the mode of kind combines.Compound location mode is exactly to position threaded fastener and workpiece simultaneously, this Location mode is suitable for the situation that workpiece weld is porose, and nut typically uses the mode of alignment pin to position workpiece simultaneously, I.e. alignment pin is step, and the part that alignment pin diameter is big is inserted in the hole of workpiece weld, and the screwed hole of nut inserts alignment pin The part that diameter is little, is equipped with locating surface the most again and positions, and workpiece and the alignment pin of compound location all use same location Pin and locating surface position.Workpiece is positioned by the general mode using hole, location and locating surface in location of bolt simultaneously, i.e. spiral shell Bolt is inserted into positioning in hole behind the hole of workpiece weld, is equipped with locating surface the most again and positions.Location-independent mode is just Being to position threaded fastener and workpiece respectively, it is fixed that threaded fastener and workpiece have independent detent mechanism to carry out respectively Position, is not related between detent mechanism and the detent mechanism of workpiece of threaded fastener.Alignment pin and locating surface are only to nut Positioning, bolt is only positioned by hole, location and locating surface, and limit and the profile of workpiece are positioned by limited post, (inclination) The face of workpiece is positioned by location vertical pole (eccentric positioning tube), alignment pin to the hole of workpiece (include the hole of weld and other Local hole) position.Integrated positioning is exactly that the compound mode combined with location-independent that positions positions, and is used for multiple Close the mode being aided with location-independent in the case of workpiece can not be positioned by location completely again, namely with alignment pin, location While threaded fastener and workpiece are positioned by hole, locating surface, re-use limited post, (bias is fixed for (inclination) location vertical pole Position cylinder) and alignment pin workpiece is positioned.It can in addition contain position by the mode of light beam irradiation, light beam will be launched Light source is fixed on equipment, marks in the position of workpiece welding threaded fastener, and the luminous point that light beam is radiated on workpiece is i.e. For the welding position of threaded fastener, when luminous point overlaps with the labelling on workpiece, i.e. complete the location to workpiece.Ordinary circumstance Lower nut screwed hole positions, and special circumstances lower nut can also use profile to position, and namely hole, location positions. In the case of bolt is porose, bolt can also position with alignment pin.Alignment pin and hole, location are that stationary type vertical is in ground Face (horizontal plane), it is also possible to be rotary and with ground (horizontal plane) at an angle.Screw bolt and nut can be positioned at workpiece Any direction such as top, lower section, front, right, left and right.No matter it is the location of threaded fastener or determining of workpiece Position, it is necessary to its front, back, left, right, up, down six direction is limited the position of object just can be made to have uniqueness, the most fixed Position.Alignment pin, hole, location can limit four direction, and limited post, (inclination) location vertical pole (eccentric positioning tube), locating surface can limit Both direction.

In order to avoid the arc light in welding is to operator's eyes and the injury of facial skin, the present invention is also equipped with arc light gear Plate.Before welding, welding machine sets the welding parameters such as electric current, voltage, wire feed rate, gas flow.By hold-down mechanism and folder The formula welding gun of holding moves down, and regulation hold-down mechanism is forward and backward, the position of upper and lower all directions so that it is can collet threaded securing member and workpiece (sheet metal component or pipe fitting)；Regulate the welding gun on clamping device and the distance of weld and angle again.Mix up rear Power Component Driving hold-down mechanism and clamping device to move up reset, equipment is in state to be welded.When formally 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 Yu workpiece The place of connecing welds, when with stud welding machine welding threaded fastener, and stud welding gun one threaded fastener of welding.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 required, 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 welded is taken out by operator, and whole welding process completes, subsequently Carry out the welding of next threaded fastener, so circulate operation.The compression of the most each functional unit, weld, the operation such as reset Content is controlled by the control system of equipment, and operator only needs piece installing starting device pickup, whole process one people just can Complete, and simple to operate, it is not required to carry out professional training, training just can operate a little.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, then 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, when equipment temporarily leaves unused, 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 common manual operation welding gun, often i.e. can 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. If desired for bulky, heavy parts that personnel cannot move or machinery equipment carry out arc stud welding, then can be stud The clipping welding gun of weldering is replaced with existing common hand-held welding gun, play its flexibly, be not required to move the advantage of welding workpiece.This Bright threaded fastener need not process salient point, and threaded fastener can be replaced to be connected with the staking of workpiece.It is a kind of real one Machine is multiplex, the threaded fastener welding equipment of one-machine-multi-function.

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

The invention has the beneficial effects as follows: the welding manner of this threaded fastener of existing resistance projection-welding, is Pressure Welding One, needs to apply the pressure of up to 3000N-10000N during welding.And this equipment uses MAG weldering, TIG weldering, MIG weldering, stud The welding manners such as weldering and MIG soldering, belong to arc welding in welds types.Welding itself is not required to pressure, simply for solid Fixed, collet threaded securing member and workpiece, prevent the purpose of welding deformation from just applying suitable pressure when welding, but this power be remote The pressure not having resistance projection-welding is big, only about 1/10th of electric resistance welding pressure.Owing to welding pressure is little, thus without to behaviour Author damages.The workpiece that some profiles and welding position are more special is such as entered in the inner side of U-shaped sheet metal component sidewall The welding of row threaded fastener, owing to have employed the welding manner of special detent mechanism and arc-welding, also can easily realize, thus Avoid using the mode of staking to fix threaded fastener (cost of staking threaded fastener is high, efficiency is low).The present invention is dependent on Threaded fastener and workpiece are melted and realize welding by arc heat, and threaded fastener need not process salient point, simple in construction.Screw thread Securing member and the welding of tubing (cross section of tubing is circular or polygon, and tubing is internally hollow or solid), this Bright also have obvious advantage.As welded with pipe (hollow or solid), threaded fastener only has one with the contact surface of pipe Line, traditional resistance projection-welding requires that the salient point of threaded fastener need to contact with pipe, and otherwise welding just cannot realize.That is Threaded fastener requires height, operator's bad assurance during welding with the position degree of pipe fitting.If the tube wall of tubing (hollow pipe) is too Thin, light wall pipe be collapsed by pipe fitting compressive strain, and will be caused when weld strength also can reduce welding by the pressure of resistance projection-welding Pressure needed for welding can not meet.If the solid tubes that tube wall is the thickest or caliber is the biggest, will result in screw threads for fastening Part does not mates with workpiece, makes welding difficulty increase follow on slab and carries out one reason of resistance projection-welding.Cross section is polygon The tubing of shape, owing to the limit of this kind of tubing is all plane, during welding, threaded fastener and tubing position degree require on the contrary to reduce not Few.If but to weld on tubing seamed edge, then there will be the problem welding with on pipe.The present invention uses electricity Arc Welding Principles, need not powerful pressure during welding, also not against resistance heat, and can also add filler metal during welding.With The Fundamentals of Welding of resistance projection-welding are entirely different, when threaded fastener welds with tubing, and the most solid tubing, hollow pipe Material, thick tubing, thin tubing, is circular tubing or polygonal tubing can easily realize weldering regardless of cross section Connect.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 not Rust steel, moreover it is possible to welding medium and high carbon steel, steel alloy non-ferrous metal, dissimilar metal even foreign material.

Traditional MAG weldering, TIG weld, MIG welds, the method for MIG Welding threaded fastener, without pressed positioning mechanism, and Use human weld.Human weld once can only weld a bit, and a threaded fastener typically need to weld 2-4 point, then the most just Needing welding 2-4 time, the welding efficiency which results in traditional arc welding threaded fastener is the lowest.Human weld is to operation The level of skill of person requires the highest, needs the training through specialty to be competent at.Threaded fastener is welded on workpiece, needs Positioning threaded fastener and workpiece, simplest method is exactly to take self-align mode.It is exactly at threaded fastener One positioning boss of upper processing, the shape of positioning boss coordinates with the hole on workpiece with size, and during welding, threaded fastener is convex In platform prevents the hole of workpiece, then welding.But threaded fastener is not retrained by external force, and once can only weld One solder joint, this results in inequality of being heated and easily causes one end of threaded fastener and upwarp, it is impossible to be adjacent to workpiece, owing to not protecting Protect measure, screw thread also can be stained with spatter." a kind of weld jig machine preventing welding slag from penetrating into nut bore mentioned above Structure ", prevent welding slag from entering in nut by anti-splashing alignment pin, but the material of this alignment pin is not illustrated, with absolutely Edge material result is best.Though with also playing the effect of pre-welding slag preventing if metal material, but this anti-splashing alignment pin and spiral shell Female thread contact can produce contact resistance, the screw thread in the 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 defect.First there is no hold down gag, convex if not prior resistance 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), this patent has fine preventive effect to the splashing of nut, the most inapplicable to bolt.If met Welding to tubing with nut, this patent does not has corresponding technical scheme yet." a kind of sheet material quickly positions work with nut-welding Dress ", this patent uses nut positioning element to carry out clamp nut, and the problem that nut upwarps has obtained good solution.But the most only fit Close welding of nut and sheet material, if the welding of other forms, as bolt carry out with metal sheet welding, nut and the weldering of tubing Connect or bolt is the most inapplicable with welding of tubing.And in practical operation, needing a human hand held positioning tool, another people enters The location work of andante material and nut, two people work in coordination with operation and just can complete, and are also to need human weld after having positioned.This location Frock not only operates that number is many, and efficiency is the lowest, the highest to the skill set requirements of welder.No matter it is that " one 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 ", substantially simply a kind of work Clamps, functions only as location and the protective action of threaded fastener, does not has the function of welding, the welding of threaded fastener Also need to welding equipment complete.Although traditional arc stud welding can once complete when welding screw or nut, but workman exists Not only stud or nut are welded on the position that workpiece specifies exactly during welding, threaded fastener to be ensured With the perpendicularity of workpiece, which results in tradition arc stud welding positioning precision poor, perpendicularity is unstable, and efficiency is the highest.The present invention Separately design different detent mechanism, clamp system and welding guns for different workpiece and different threaded fasteners, can realize The sheet metal component (including U-shaped sheet metal component) of variously-shaped and thickness, variously-shaped and thickness tubing respectively with various types of spiral shells The welding of stricture of vagina securing member.This welding equipment is located on ground, is not required to manpower and helps, and hold-down mechanism is provided dynamic by Power Component Power not only saves manpower, is ensureing threaded fastener and the laminating degree of workpiece, perpendicularity and is preventing splashing from damaging the same of screw thread Time efficiency the highest.Detent mechanism uses high-strength insulating material or in equipment with the contact portion of threaded fastener screw thread Carry out insulation processing with the position of thread contact, stop the contact resistance damage to screw thread.Welding equipment is tight in collet threaded Welding while firmware, automaticity is high.Welding is achieved by installing many clipping welding guns on welding equipment Once complete, welding efficiency is high；Work one people such as threaded fastener and the location of workpiece, welding can complete, before welding only Need to set every welding parameter, and adjust detent mechanism, hold-down mechanism, the position of clipping welding gun just can easily be welded, Low to the skill set requirements of operator, save human cost.The welding gun of arc stud welding is changed into clipping by traditional hand-held, fixing On the clamping device of equipment, Power Component drive.When ensure that arc stud welding the laminating of nut and workpiece closely and stud with Workpiece is vertical；Need not manual operation welding gun during welding, efficiency is the highest.
