The specific embodiment

Please refer to shown in Fig. 2 to Fig. 8, it has demonstrated the concrete structure of the preferred embodiment of the utility model, and this welding gun includeshandle 10,air inlet pipe 20, weldinggun rotating joint 30,gauge tap 40,torch head 50 andtorch head 60.

Wherein, as in Figure 3-5, describedtorch head 60 is connected in the front end oftorch head 50, and thistorch head 50 is extended type designs, and its front end is bowed downward to arc shape.During due to welding,torch head 60 can produce high heat, and king-size torch head 50 structures, the thermal energy transmission that can extendtorch head 60, therebytorch head 50 is connected in one end heat ofhandle 10 to be scattered and disappeared in a large number in transmittance process, makeshandle 10 can not feel hot.And the Front-end Design camber shape oftorch head 50 is made to form betweentorch head 60 and operating personnel certain angle, thereby operating personnel can hold the position of welding better, the comfort while increasing operation.

Thishandle 10 is to be snapped together and formed by left outsideshell 11 andright casing 12, in interior formation oneaccommodating cavity 13 ofhandle 10, thishandle 10 is divided into frontend installation portion 15, middlehand grip portion 17 and rearend connecting portion 16 from front to back, this frontend installation portion 15 is for fixing weldinggun rotating joint 30, mountinghandle fixture 14 on this rearend connecting portion 16, and inhandle fixture 14, have a conduit, for importing protective gas; Thisair inlet pipe 20 extend inhandle 10 and is connected in welding adapter from rearend connecting portion 16, by this weldinggun rotating joint 30, protective gas is led totorch head 50, bytorch head 60, is sprayed.

The structure of described weldinggun rotating joint 30 as shown in Figure 7; in this weldinggun rotating joint 30, be provided with four holes, one is thatwelding wire hole 31 for passing into welding wire, one are thatpore 32 for passing into protective gas, another two are for passing into theline hole 33 of Electric Machine Control line.During normal use, in thiswelding wire hole 31, pass into welding wire, thispore 32 connects inair inlet pipe 20, twoline holes 33 control line.Wherein, thiswelding wire hole 31 connects the front/rear end of weldinggun rotating joint 30, andpore 32 communicates withwelding wire hole 31 in weldinggun rotating joint 30, thereby in weldinggun rotating joint 30, the protective gas of importing is melted to welding wire mutually.

As shown in Figure 5,6, the head end of describedtorch head 50 is connected on weldinggun rotating joint 30, and this weldinggun rotating joint 30 is by buckle structure, to be fastened in the frontend installation portion 15 of handle 10.As shown in Figure 7,8, this buckle structure comprises the first concavo-convex fixture block 34 of being located at weldinggun rotating joint 30 outer walls and the second concavo-convex fixture block 153 of being located at frontend installation portion 15, and this first, second concavo-convex fixture block 34,153 matches and is fixed.In the present embodiment, the internal face of described frontend installation portion 15 is equipped withmany fins 151, between adjacent twofins 151, form the space 152 for 30 heat radiations of welding gun rotating joint, be conducive to heat radiation, described the second concavo-convex fixture block 153 is formed on the inner peripheral surface offin 151, thereby the first concavo-convex fixture block 34 and the second concavo-convex fixture block 153 match to fix welding gun rotating joint 30.By weldinggun rotating joint 30 being installed on to the front end ofhandle 10, rather than be provided withhandle 10 rear ends, and its benefit is to avoidtorch head 50 to extend inhandle 10, while causing welding, heat imports to handle 10 bytorch head 50, make operating personnel holdheating handle 10 and sweat, uncomfortable during work.

Describedgauge tap 40 is located at the head end below of welding gun, on thisgauge tap 40, be connected with power connection 43, this power line is connected with the interior control line inline hole 33 of weldinggun rotating joint 30, by this weldinggun rotating joint 30 andgauge tap 40 being all located to the head end of welding gun, thereby power line is done to obtain the very short control line that just enough connects, connect up convenient, guaranteed the clean and tidy ofhandle 10 interior wirings.

In sum, design focal point of the present utility model is, it is mainly weldinggun rotating joint 30 to be moved on to together withtorch head 50 to the front end ofhandle 10, with the fixing weldinggun rotating joint 30 of the frontend installation portion 15 ofhandle 10, like this,torch head 50 stretches out outsidehandle 10, and be to be no longer contained inhandle 10, thereby on the onehand torch head 50 directly contacts withoutside air handle 10 is outer, is easy to dispel the heat, and makes to be transmitted to the heat minimizing of weldinggun rotating joint 30; On the other hand, weldinggun rotating joint 30 is provided in a side of the front end ofhandle 10, is no longer located at the middle rear end ofhandle 10, even if weldinggun rotating joint 30 is produced heat like this, can not be transmitted to the middlehand grip portion 17 ofhandle 10, in the middle of making,hand grip portion 17 can not generate heat, and increases the comfortableness of operating personnel's handle 10 yet.

In addition, weldinggun rotating joint 30 is advanced to front end by the rear end ofhandle 10, make weldinggun rotating joint 30 can be positioned at the top ofgauge tap 40, when thereby the power line ofgauge tap 40 connects the control line of weldinggun rotating joint 30, power line only need to be done to such an extent that very shortly just can, without the hand end of moving power line to handle 10 as the conventional practice trouble of wiring again, can guarantee by this clean and tidy ofhandle 10 interior wirings, save wiring cost.

The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore any trickle modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
