[technical field]
The utility model relates to the arcing soldering equipment, relates in particular to a kind of arc pulling type stud welding gun.
[background technology]
Stud welding gun is widely used in automobile, shipbuilding, aviation, locomotive and other panel beating industry.Stud welding gun utilizes the electric current of welding machine output, form electric arc by being lifted between welding sheet metal component and the weldering nail of electromagnet, the welding position of weldering nail and sheet metal component is melted simultaneously, control by controller again, turn-off current of electromagnet, the conducting end part drives the molten bath that the weldering nail is pressed into sheet metal component under the pressure effect of spring, once welding is finished.Whole welding process only needs a few tens of milliseconds.Therefore the work characteristics of welding gun is: the time is short, frequency is high, perpendicular positioning, need good repetition operating characteristic.
Existing welding gun generally adopts electromagnet to promote, and conducting end adopts the basis brass cover as sliding bearing, and the rifle line of welding gun is common cable.Exist owing to have remanent magnetism after the electromagnet outage, after the electromagnet outage, double-screw bolt fell slow, was easy to generate rosin joint; Common brass bushing is not wear-resisting, and influence welding quality once long heavy wear service time; The rifle line of welding gun fractures easily owing to often drag, and has reduced welding gun and has used service life.
[summary of the invention]
After the technical problems to be solved in the utility model provided a kind of electromagnet outage, the double-screw bolt falling speed was fast, the arc pulling type stud welding gun that welding quality is good.
It is little that the technical problems to be solved in the utility model provides a kind of moving component wearing and tearing, the stud welding gun of long service life.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is a kind of arc pulling type stud welding gun, comprise shell, handle, conducting end group, conductive chuck, insulating base, electromagnet, control line and cable, insulating base is fixed on the front portion of shell, electromagnet is fixed in the shell, and conductive chuck is fixed on the front end of conducting end group, and the front portion of conducting end group is by the sliding supported condition that is installed in the insulating base; The rear end of conducting end group is by the sliding supported condition that is installed in the electromagnet; Electromagnet armature is equipped with at the rear portion of conducting end group, and the separation pad of non-magnet material is housed between described armature and the electromagnet.
Above-described arc pulling type stud welding gun, the thickness of described separation pad are 0.1 to 0.5 millimeter.The material of described separation pad is stainless steel or beryllium-bronze.
Above-described arc pulling type stud welding gun, described sliding bearing are self-lubricating bearing.Described sliding bearing is tin bronze bearing or sintered metal powder bearing.
Above-described arc pulling type stud welding gun, the connecting portion of described control line and cable and handle has encapsulate.
Conducting end group of the present utility model is raised after the electromagnet energising, the weldering nail and the welded blank that drive the conductive chuck the inside leave, between sheet material and weldering nail, produce electric arc, form the molten bath, when electromagnet cuts off the power supply, the separation pad of non-magnet material has reduced the suction of electromagnet remanent magnetism to armature, and the conducting end group can will be welded nail rapidly and is pressed into the molten bath under the pressure effect of stage clip, thereby has guaranteed the welding quality of weldering nail.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model arc pulling type stud welding gun embodiment.
Fig. 2 is the structure chart of the utility model arc pulling type stud welding gun embodiment conducting end group.
[specific embodiment]
In Fig. 1, the utility model arc pulling type stud welding gun embodiment shown in Figure 2, stud welding gun comprises rifle shell 6 and handle 32, the anti-cover 1 that splashes, end cap group 4, conductive chuck 2, locking nut 3, insulating base 5, conducting end group 27, separation pad 7, electromagnet 8, spring base 12, stage clip 13, regulates blind nut 14, protecting cover 15, near switch 24.Conducting end group 27 is made up of conducting end 2701, insulation sleeve 2702, armature 2703 and guide rod 2704.5 of electromagnet 8 and edge insulators all are fixed on the rifle shell, and the conducting end 2701 of conducting end group 27 is by insulating base 5 supportings, and guide rod 2704 is supported by electromagnet 8, and can do relative slip with insulating base 5 and electromagnet 8 vertically.Between conducting end 2701 and the insulating base 5 sliding bearing 33 is arranged, between guide rod 2704 and the electromagnet 8 sliding bearing 36 is arranged, sliding bearing 33 and 36 all adopts the tin bronze self-lubricating bearing, is not easy wearing and tearing, effectively guaranteed the linear slide of conducting end group, the life-span of having improved welding gun.Sliding bearing 33 and 36 can also adopt as self-lubricating bearings such as sintered metal powder bearings.Conductive chuck 2 is fixed on by locking nut 3 on the conducting end 2701 of conducting end group 27, and it is 0.2 millimeter beryllium-bronze separation pad 7 that thickness is arranged between the armature 2703 of conducting end group 27 and the electromagnet 8.Conducting end group 27 is raised after electromagnet 8 energisings, produce electric arc between the weldering nail of drive conductive chuck 2 the insides and the welded blank, between sheet material and weldering nail, form the molten bath, when electromagnet cuts off the power supply, the conducting end group can will be welded nail rapidly and is pressed into the molten bath under the pressure effect of stage clip 13, guarantee welding quality.The effect of separation pad 7 is to reduce the suction of electromagnet outage back remanent magnetism to armature, prevents that double-screw bolt fell slow under the effect of stage clip 13 elastic force after the electromagnet outage.Separation pad 7 can adopt the high non-magnet material of intensity to make, as beryllium-bronze, and stainless steel etc.
