A kind of rosin joint leak inductance device for robot automatic arc stud welding machine as shown in Figure 1:, the rosin joint leak inductance
Device includes driving cylinder 1, and 2 front end of piston rod of driving cylinder 1 is provided with impact hammer 3, and the impact hammer 3 is located at arc stud welding
The tup of the welding gun pipette tips side of machine, impact hammer 3 can be located at weldering along hitting perpendicular to the axial horizontal movement of welding gun pipette tips
The stud of rifle pipette tips front end just welded, and drive cylinder 1 that the tup of impact hammer 3 is driven to hit dynamics according to weldering nail welding intensity
Setting；When impact hammer 3 hits the stud just welded, the shock feedback of impact hammer is empty shock if solder skip, can issue alarm
Signal；Weldering nail can be miscued if rosin joint.Above-mentioned driving cylinder 1 is fixed on cylinder positioning seat 4, cylinder positioning seat 4
It is mounted on by fixed plate 5 on the side wall of stud welding gun mounting base.
There is the following two kinds consideration in specific setting position about driving cylinder 1.
First is that driving cylinder 1 is arranged at welding gun pipette tips front position by specification longer cylinder positioning seat 4, at this time
Drive 2 telescopic direction of piston rod of cylinder 1 perpendicular to the axial direction of welding gun pipette tips, then impact hammer 3 is directly fixed at piston rod 2
Top.
First is that driving cylinder 1 is arranged in by specification shorter cylinder positioning seat 4 the fuselage side of stud welding machine, at this time
2 telescopic direction of piston rod of driving cylinder 1 is not orthogonal to the axial direction of welding gun pipette tips, and the hammer handle back segment of impact hammer 3 is fixedly mounted on
On connecting plate 6, by connecting, active pin 7 is mounted on piston connector 8 other end of connecting plate 6 and piston connector 8 is directly anchored to
The top of piston rod 2；By positioning, active pin 9 is connected the plate body of connecting plate 6 with connecting rod 10 and the other end of connecting rod 10 is direct simultaneously
It is fixed on one end of positioning plate 11, so that the tup of impact hammer 3 can not be along the axial movement of welding gun pipette tips, and the tail of positioning plate 11
End is fixedly mounted on cylinder positioning seat 4；When so that the piston rod 2 of driving cylinder 1 stretching out, axis of the impact hammer 3 along welding gun pipette tips
It is limited to movement by positioning plate 11 and connecting rod 10 and the tup of impact hammer 3 can only be along the axial horizontal movement perpendicular to welding gun pipette tips
To hit the stud just welded for being located at welding gun pipette tips front end.It in addition is that the position of impact hammer 3 is adjusted, even
