Detailed description of the invention
1 to 3 pair of the specific embodiment of the present invention is described further by reference to the accompanying drawings:
A kind of stud welding gun, comprise rifle shell, drive motors 14 and driven shaft 7, be enclosed with radial magnet steel 6 in driven shaft 7, driven shaft 7 upper end has and the groove welding nail 5 diameter adaptation.Rifle shell is formed by fixedly connecting by left shell 1 is relative with right shell body 2, and the front portion of rifle shell has targeting port 3, and targeting port 3 is V-shaped, and targeting port is just to the groove port of driven shaft 7, and weldering nail 5 is put into by targeting port 3, is adsorbed, fall in groove and suck by magnet steel 6.Drive motors is positioned at the rear portion of rifle shell, drive motors 14 is fixedly connected with rifle shell by motor cabinet 15, the driving shaft of drive motors 14 is leading screw, on leading screw, cover has screw 13, screw 13 is connected to the rear end of insulation sleeve 11 by screw 12, the front end of insulation sleeve 11 connects driven shaft 7, and drive motors 14 drives driven shaft 7 to move back and forth.Rifle shell front end is provided with three backstays 4, when backstay 4 is on same straight line with weldering nail 5, and can by angled with Plate Welding for weldering nail.
Driven shaft 7 is provided with locating dowel 8, and locating dowel 8 is inserted in the trepanning of the positioning sleeve 10 be fixedly connected with driven shaft 7 by spring 9.Stud welding gun also comprises guide rail 18, guide rail 18 is connected with slide block 19, and slide block 19 is fixedly connected with driven shaft 7 by contiguous block 20.Driven shaft 7, guide rail 18, slide block 19 and contiguous block 20 are conductor, guide rail 18 are connected with the negative pole of the source of welding current 17, and the positive pole of the source of welding current 17 is connected on steel plate 60 to be welded.The small of the stock of rifle shell is provided with start stop switch 16.
Weldering nail 5 puts into groove (end thereof contacts locating dowel 8) by targeting port, instead of inserts from certain endoporus of driven shaft, and labour intensity greatly reduces, and speed is fast.The contact area of the groove of weldering nail 5 and driven shaft 7 is much larger than the sectional area welding nail 5, so pick-up current is enough large during welding.In addition, drive motors 14 can be stepper motor, linear electric motors, direct current generator or cylinder.For arc pulling type welding, driven shaft drives weldering to follow closely the arcing action had backward; For condenser type welding, driven shaft does not have arcing action with weldering nail.
Arc pulling type welds: put into by targeting port 3 by weldering nail 5, press start stop switch 16, drive motors 14 rotates, and screw 13 advances on the driving shaft, by driven shaft 7, weldering nail 5 is delivered to solder side.Weldering nail 5 and steel plate 60 Contact, adopt PLC or Single-chip Controlling drive motors 14 first arcing one end backward distance to move forward again, weld nail 5 firmly integrally welded with steel plate 60 under instantaneous high-temperature.Or weldering nail 5 keeps contacting with steel plate 60 when starting, and presses start stop switch 16, while starting welding current, drive motors 14 first arcing one end backward distance moves forward again, completes above-mentioned welding action.
Capacitor discharge type welds: this stud welding gun, and at removal backstay 4, drive motors 14 removal or do not work, keeps driven shaft 7 to fix, and weldering can be made to follow closely 5 and directly contact with steel plate 60, the source of welding current 17 positive and negative electrode is energized, and realizes capacitor discharge type and welds.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited in above-mentioned citing, and the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
