The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, before parallel welding machine welding head was transformed: soldering tip 7 was provided with right electrode 1 and left electrode 2, each electrode is provided with electrode contact (HOLD) 3 respectively, right electrode links to each other with negative pole with the positive pole of power supply 9 with 8 by cable 6 respectively with left electrode, and welded article 4 forms parallel weldering solder joint (two point) 5 under placing electrode during work.
As shown in Figure 2, soldering tip 18 is provided with right electrode 11 and left electrode 10, each electrode is provided with electrode contact (HOLD) 12 respectively, right electrode links to each other by the positive pole of cable with power supply 19, at the fixing butt welding lower clamp 15 of described parallel welding machine welding head base position, (as shown in Figure 3, the butt welding lower clamp is by fixing successively from bottom to top base 21, support column 22 and bottom electrode 23 are formed), bottom electrode is positioned under the right electrode of parallel welding machine welding head, connecting the power turn-on anchor clamps is arranged between support column and the bottom electrode, connect the power turn-on anchor clamps and connect bottom electrode and power cathode respectively, welded article 13 places and forms butt welding solder joint (single-point) 17 between right electrode and the bottom electrode during work.Butt welding lower clamp base is fixed in parallel welding machine welding head base, and support column and bottom electrode are concentric column, and the support column radius is greater than the bottom electrode radius.
The utility model will connect the left electrode of parallel weldering (-) cable and install the fixedly bottom electrode of butt welding lower clamp additional by connecting the access of power turn-on anchor clamps, make and install butt welding lower clamp and the right electrode of parallel welding machine (+) formation loop additional, butt welding lower clamp electrode and the right electrode vertical current of parallel welding machine are reached single-point to welding (parallel welding machine left side electrode this moment (-) is to disconnect) through contact resistance.
Only need the butt welding lower clamp is removed when the parallel weldering of butt welding conversion, cable is inserted parallel welding machine left side electrode (-), two point is parallel have been welded thereby just change into back.
The spot-welding equipment circuit is closed, exactly because can circuit be that closed just making equates at whole closed circuit and electric current everywhere; But resistance everywhere is different, and particularly in the fixing resistance maximum of contact position not, this resistance is contact resistance in physics.According to the fuel factor law (also being Joule's law) of electric current, Q=CI
2Rt as can be known, electric current equates that the position heating that then resistance is big more is high more, the contact resistance maximum of the contact position of contact that welds when point is welded in welding and soldered metallic object, then also just at most, solder joint is again the lower alloy of fusing point to the electric heating that produces at this position, the easy fusing of nature naturally.The high-temperature electric arc that utilizes positive and negative polarities to produce when instantaneous short circuit melts scolder and the materials to be welded on the welded article, reaches the purpose that makes their combinations.Alloy solder joint core after the fusing is stained with and is combined on the welded article body after supercooling just has been bonded in one to welding object.Exerts pressure by electrode in weldment combination back, the method that the resistance heat that utilizes contact-making surface and the adjacent domain of electric current by joint to produce welds is called electric resistance welding.Electric resistance welding has the high and low cost of production efficiency, saves material, is easy to characteristics such as automation.So by the provable parallel weldering of above mash welder operation principle and the operation principle of butt welding is the same parallel welding machine to be transformed parallel soldering tip, according to the resistance welder principle, the design anchor clamps change parallel soldering tip into general soldering tip.
