Straight line soldering turret such as Fig. 2, it is by straight line soldering turret base 25, moving sliding base 26, on, bottom arm 18,19, on, bottom electrode bar 20,21 form, straight line soldering turret base 25 left sides are affixed by screw and rotating disc 4 right sides, the axis of the piston 8 right-hand members pass and by the hole on rotating disc 4 and the straight line soldering turret base 25 from protecgulum 6, be connected with upper electrode arm 18 by attaching nut 22 on its front end, straight line soldering turret base has dovetail groove on the 25 lower right sides, the left side of moving sliding base 26 is a dovetails, it and base 25 bottom dovetail grooves are matched, moving sliding base 26 and straight line soldering turret base 25 are fixedlyed connected by screw, moving sliding base 26 right-hand members are socket cap, and internal thread hole is arranged on it, and bottom arm 19 is screwed in this internal thread hole, its junction is set with horn adapter sleeve 27, on, bottom arm 18,19 also pass through chuck 30 respectively with last, bottom electrode bar 20,21 is affixed.

Principle of the present utility model is such: transformer 1 joins together with main control loop, as long as press handgrip switch 28, just has electric current to flow into electrode tip, is suspended on the guide rail by 29 activities of balance suspension rod when the utility model uses.When the utility model is in straight line soldering turret motion state, as Fig. 2, source of the gas gas enters electromagnetic gas valve 5 backs directly enter cylinder block 2 piston cavities from the pore on the cylinder protecgulum 6 by electromagnetic valve right air chamber, gas atmosphere is moved to the left and drives upper electrode arm 18 that cylinder axis 8 is connected to moving left to left limit with piston 9, at this moment two welding electrode heads open, the workpiece that will process is placed between two electrode tips, the electromagnetic gas valve laggard promoting the circulation of qi body commutation of switching on, be that gas enters left air chamber by the pore on the dividing wall, gas atmosphere moves right piston 9 and drives the axis of the piston 8, make the upper electrode arm 18 that is connected with the axis of the piston 8 move right, workpiece is tightly withstood, then press handgrip switch 28, transformer 1 is connected power supply and is sent welding current, welding current is by last, bottom arm 18,19 and electrode stem 20,21 flow through the end points of tightly clamping with workpiece, the welding current that flows through dissolves workpiece and becomes one, later transformer 1 deenergization, welding current disappears, electromagnetic gas valve 5 power interruption recoverings enter the right ventricle to gas by the hole on the cylinder protecgulum 6, make two electrode tips separately, the workpiece welding finishes, and action just can be finished the welding of whole work-piece and so forth.If during the irregular workpiece of welding, the rotatable spacing handle 11 of straight line soldering turret, when making the spacing hook 10 of straight line soldering turret throw off the work of stop nut 14(straight line soldering turret, the spacing hook 12 of camber line soldering turret must be thrown off stop nut 14 and locked earlier), the back work stroke of the axis of the piston 8 is strengthened, so that irregular workpiece puts between the soldering turret electrode tip, and then the spacing hook 10 of the straight line soldering turret that closes, normal welding sequence just.

When the utility model is in camber line soldering turret motion state, as Fig. 1, after source of the gas gas enters electromagnetic gas valve 5, enter the left air chamber of piston cavity from the pore on the cylinder dividing wall by electromagnetic valve, gas atmosphere moves right piston 9, and drive the axis of the piston 8 moves to right limit, it is that the center clockwise rotates with axle 24 that the small clevis pin with head 23 by its right-hand member both sides of moving to right of the axis of the piston 8 makes shift fork swing arm 17, and drive bottom arm 19 and 21 rotations of bottom electrode bar thereof, electrode tip is opened, workpiece to be processed is placed between two electrode tips, the laggard promoting the circulation of qi body commutation of electromagnetic gas valve 5 energisings, be that gas directly enters right air chamber by the valve on the cylinder protecgulum 6, gas atmosphere is moved to the left and drives the axis of the piston 8 with piston 9 and moves left to left limit, the axis of the piston 8 moves to left and makes shift fork swing arm 17 is that the center rotates counterclockwise with axle 24, and drive bottom arm 19 and 21 rotations of bottom electrode bar thereof, make the electrode tip closure, workpiece tightly is clipped between two electrode tips, press handgrip switch 28, transformer 1 is connected power supply and is exported welding current, welding current is by last, bottom arm 18,19 and on, bottom electrode bar 20,21 flow through the end points of tightly clamping with workpiece, make workpiece be melted into one at solder joint, later transformer 1 deenergization, welding current disappears, electromagnetic gas valve 5 power interruption recoverings are to original state, two electrode tips are opened, the workpiece means of spot welds finishes, and repeats above-mentioned action later on, just can finish the welding of whole work-piece.If the special-shaped workpiece of welding, need to regulate electrode tip open apart from the time, when the rotatable spacing handle 13 of camber line soldering turret makes the spacing hook 12 of camber line soldering turret throw off the work of stop nut 14(camber line soldering turret, the spacing hook 10 of straight line soldering turret must be thrown off stop nut 14 earlier, and locked), the back work stroke of the axis of the piston 8 is strengthened, to put into special-shaped workpiece, the spacing hook 12 of the camber line soldering turret that closes then, just normal welding sequence.

The utility model has the advantages that the welding mechanism with camber line and straight line exchange, transformer and welding mechanism one have been saved the secondary Water cooling cable, its volume is little, capacity is low, low production cost, and is easy for installation, flexible operation, and energy savings is convenient to computer and is carried out timesharing control.
