Abstract
The utility model provides a kind of arc stud welding guiding mechanism for mistake proofing, comprise guide pin bushing and the anti-cover that splashes, guide pin bushing and the anti-cover that splashes are all assemblied on arc stud welding muzzle, it is characterized in that: the inner side at guide pin bushing is longitudinally provided with gathering sill, longitudinally be provided with guide pad, described gathering sill and described guide pad assembly connection in anti-outside of splashing cover.Inner side at guide pin bushing is longitudinally provided with more than at least two gathering sill, and the anti-cover outside of splashing is provided with the guide pad consistent with gathering sill position and quantity.The utility model not only can prevent the wrong specification of arc stud welding, and can ensure the perpendicularity of double-screw bolt and welded piece, and then ensures the welding quality of double-screw bolt.
Description
Technical field
The utility model relates to a kind of guiding mechanism, and particularly a kind of arc stud welding guiding mechanism for mistake proofing, belongs to technical field of welding equipment.
Background technology
Arc stud welding be a kind of by metallic stud and similarly metal parts be soldered to a kind of welding method on metal works.In prior art, in order to make the manual stud welding gun position to regulation by stud welding accurately, need on stud welding gun, increase the guide pin bushing mating with the anti-cover that splashes of stud welding gun, guide pin bushing has the effect of the vertical workpiece welding of auxiliary stud welding gun.
Existing arc stud welding guide pin bushing and anti-splashing while covering on welding, be first placed into the stud welding gun of clamping stud in guide pin bushing, and be pressed on welded piece, the compression of welding gun inner spring, and double-screw bolt end face is close to surface of the work; Press weldering trigger for gun, enter the striking stage, the energising of stud welding gun electromagnet makes double-screw bolt promote the electric arc that ignites, clean weld zone coating and greasy dirt, and this electric current is called striking electric current; In latter stage in striking stage, welding gun passes to stronger welding current automatically according to preset value, fusing double-screw bolt termination and weld zone; Before welding arc extinguishes on schedule, solenoid degaussing, spring promotes double-screw bolt termination and is written into fusion zone; In the time of double-screw bolt and workpiece short circuit, arc extinction, but welding current still exists, time delay is zero to arc voltage, and now welding current finishes welding gun medi-spring during this period of time the pressure of double-screw bolt is not cancelled, and molten pool metal is extruded, form recrystallization plasticity jointing, welding gun is mentioned, and welding process finishes.Can find out in whole welding process, guide pin bushing and the anti-cover that splashes are playing a part auxiliary welding attitude always.
Along with the extensive application of arc stud welding also reflects some problems gradually, first at the station that need to weld multiple double-screw bolt, often there is the situation of the wrong double-screw bolt specification of weldering, reason is operative employee in the time of welding with wrong welding gun, although guide pin bushing and the anti-cover that splashes do not mate, but stud welding gun still can touch workpiece and weld, this just makes double-screw bolt can not find in time wrong weldering in the time of welding; Secondly, in double-screw bolt joint forming process, it is vertical with workpiece that double-screw bolt falling direction should keep as far as possible, the angle of deflection remains on welding quality within 5 degree to be affected little, exceed this scope welding quality can be subject to certain impact, and when welding gun hand-manipulated, double-screw bolt perpendicularity is held by operator to a great extent, be subject to the impact of human factor larger, if double-screw bolt inserts the immediate inclination in molten bath, just may make double-screw bolt occur on one side lack of penetration, fly and another side liquid metals is squeezed, finally cause joint quality to reduce; In addition, arc stud welding guide pin bushing and double-screw bolt rifle anti-splashed and covers on the situation that there will be unavoidably wearing and tearing after welding repeatedly, makes to be difficult to ensure double-screw bolt perpendicularity, and then affects welding quality.
Utility model content
For above deficiency, the utility model provides a kind of arc stud welding guiding mechanism for mistake proofing, not only can prevent the wrong specification of arc stud welding, and can ensure the perpendicularity of double-screw bolt and welded piece.
The technical solution of the utility model: for the arc stud welding guiding mechanism of mistake proofing, comprise guide pin bushing and the anti-cover that splashes, guide pin bushing and the anti-cover that splashes are all assemblied on arc stud welding muzzle, it is characterized in that: the inner side at guide pin bushing is longitudinally provided with gathering sill, longitudinally be provided with guide pad, described gathering sill and described guide pad assembly connection in anti-outside of splashing cover.
Inner side at guide pin bushing is longitudinally provided with more than at least two gathering sill, and the anti-cover outside of splashing is provided with the guide pad consistent with gathering sill position and quantity.
The utlity model has following advantage: the utility model is that guide pin bushing and the anti-cover that splashes are processed again, owing to increasing gathering sill and increase guide pad on guide pin bushing on the anti-cover that splashes, make anti-splash cover and perfectly combination of guide pin bushing, especially the quantity of gathering sill and guide pad is designed to more than two, ensure the perpendicularity of double-screw bolt and welded piece, greatly reduced the rosin joint rate of double-screw bolt; In addition, the position of gathering sill and guide pad can be set according to the specification of double-screw bolt to be welded, and the double-screw bolt that the different position of gathering sill and guide pad is corresponding different has so just prevented from welding the situation of many double-screw bolts station arc stud welding mistake specification; In addition, the gathering sill of increase and guide pad, can not rotate in can prevent splashing cover and guide pin bushing, reduced wear extent, ensured the welding quality of double-screw bolt.
