It comprises that also one is arranged on the locating piece 11 on the rifle shell 1
, and this locating piece 11 falls away from mother at this public access cover 6 and connects the front end face that cover propped up connector 4 at 7 o'clock.
A kind of stud welding gun in
present embodiment, it comprises rifle shell 1 and is arranged on the end cap group 2 on the rifle shell 1.Said end cap group 2 comprises two aluminium covers and centring ring; Be positioned at the aluminium cover 21 and rifle shell 1 clamping mutually of rear end; The aluminium cover 22 that is positioned at front end is connected through screw thread with centring ring; The aluminium cover 21 that is positioned at the rear end is provided with the guide rod that two axis with conductive shaft 3 parallel, the aluminium that is positioned at front end overlap 22 can slide relatively be arranged on the guide rod.The aluminium cover 22 that is positioned at front end can slide on guide rod according to the double-screw bolt of different length roughly to satisfy the height that double-screw bolt stretches out centring ring; And then,, double-screw bolt meets processing request so that stretching out the length of centring ring further through regulating the height that centring ring and the screw thread accurate adjustment double-screw bolt that is positioned at front end stretch out centring ring.
because the linearity of guide rod processing typing, and the formed straight line in axle center and the guide rod of axle center and the aluminium cover 21 that is positioned at the rear end that therefore is positioned at the aluminium cover 22 of front end parallels.Therefore, in process, also just can be guaranteed by the linearity of the double-screw bolt of end cap group 2 location.
this rifle shell 1, the aluminium cover 21 that is positioned at the rear end and the common cavity that forms of centring ring include conductive shaft 3, connector 4, insulation sleeve 5, public access cover 6 and mother and connect cover 7 in this cavity.
The front end of
conductive shaft 3 is connected with conductive chuck.The coaxial axle sleeve 9 that is arranged with on the conductive shaft 3, the outer rim of this axle sleeve 9 are provided with the backstay 10 that extends laterally, offer on the said rifle shell 1 to be used for and this backstay 10 hole of clamping mutually.Armature 8 is arranged on the rear end of public access cover 6, and public access cover 6 drives conductive shafts 3 and slides, and axle sleeve 9 is arranged on the front portion of conductive shaft 3, so axle sleeve 9 limited conductive shaft 3 beating in welding process, has guaranteed the quality of double-screw bolt in welding process.
The setting that is connected with the front end of connector 4 of
rear end of conductive shaft 3, connector 4 is a cuboid, the center line of the axis of this conductive shaft 3 and connector 4 coincides.Connector 4 setting that also links to each other with a flexible cable, the other end and the control circuit of flexible cable are electrically connected.Flexible cable lighter weight, the frictional force that in sliding process, produces are also just less.
connector 4 the front end of rear end through threaded engagement and insulation sleeve 5 be fixedly connected, the axis of the axis of insulation sleeve 5 and this conductive shaft 3 coincides, insulation sleeve 5 is a wood materials, plays insulation effect.
The front end of the rear end of
insulation sleeve 5 and public access cover 6 is connected, and the rear end of this public access cover 6 is provided with an armature 8, and armature 8 be soft iron, and soft iron is magnetized putting into magnetic field at once, after magnetic field disappears, demagnetizes at once again.Therefore public access cover 6 is fast and stable with the process of female absorption that connects cover 7 and disengaging.Armature 8 is cross, on the axis that is centered close to this conductive shaft 3 of this cross armature 8.Between armature 8 and insulation sleeve 5, public access cover 6 also comprises a bullet with taper surface.
when hot-wire coil was switched on, mother connect cover 7 and produces magnetic, and armature 8 is produced suction; Armature 8 drive public access covers 6 slide to mother and connect cover 7; Produce electric arc between the double-screw bolt of drive conductive chuck the inside and the welded plate, between welded plate and double-screw bolt, produce the molten bath, when hot-wire coil cuts off the power supply; Conductive shaft 3 can promptly be pressed into molten-bath arc welding with double-screw bolt and be connected on the welded plate under the reaction of spring 12.
this welding gun comprises that also one is arranged on the locating piece 11 on the rifle shell 1, and this locating piece 11 falls away from mother at this public access cover 6 and connects the front end face that cover propped up connector 4 at 7 o'clock.Can also regulate the distance that conductive shaft 3 falls through regulating the size of locating piece 11, also just regulate the welding and assembling height between double-screw bolt and the welded plate simultaneously.
The present invention adopts above structure, has the following advantages:
1, compact conformation, welding operation is easy;
2, can process the double-screw bolt of all lengths;
The axle center accurate positioning of
3, conductive shaft 3 guarantees that double-screw bolt and welded blank are perpendicular.
are above to combine diagram to be illustrated to specific embodiment of the present invention, clearly, on the basis of not leaving scope of the present invention and spirit, can much revise prior art and technology.In the technical field, the common knowledge of a GPRS just can be carried out diversified change in technological main idea scope of the present invention under of the present invention.
