The shape of pole changes, and reduces the high-temperature stability of electrode, and butt welding gun electrode causes to be lost, by being arranged in welding gun electrode
The loss of welding gun electrode can be effectively reduced in electrode cap.Illustratively, common electrode material starts soft at 400 DEG C or so
Change, when reaching 980 DEG C of nugget formation needs, Vickers hardness has fallen to 1/3 or so of original hardness, so as to cause electricity
Pole is partially soft in welding, and loss increases.Drawbacks described above can be overcome by strengthening electrode cap 5a made of copper disperse aluminium, 900
DEG C or so when just start to soften that this guarantees its stability at high temperature, reduce loss.
Optionally, puppet's welding mechanism further includes welding circuit, and referring again to Fig. 1, welding circuit includes the first conduction copper bar
13, the second conduction copper bar 14 and welding copper bar 15, the first conduction copper bar 13 are connect with first electrode 3 by cable 16 (see Fig. 6),
Second conduction copper bar 14 is connect with second electrode 5 by cable 16, and copper bar 15 and the first conduction copper bar 13 and the second conduction are welded
Copper bar 14 connects, and welding copper bar 15 is located between the first conduction copper bar 13 and the second conduction copper bar 14.When use puppet's welding mechanism
When butt welding point is welded, vehicle body, first electrode 3, first conduct copper bar 13, welding copper bar 15, second conducts copper bar 14 and the
Two electrodes 5 form welding circuit, and welding personnel welds welding copper bar 15 using external welding machine, provide weldering for welding circuit
Electric current is connect, realizes the welding to vehicle body.Due to using welding circuit to move away from the position of vehicle body solder joint for copper bar 15 is welded,
Keep welding personnel more convenient to the welding of vehicle body solder joint, further improves welding efficiency.
Illustratively, welding personnel, which welds average each vehicle body solder joint using common soldering turret, needs 3S, welds complicated solder joint about
4s, after this puppet's welding mechanism, the welding copper bar 15 that human weld's puppet's welding mechanism connects out, which can be realized, welds vehicle body
Spot welding, weld interval about 1.5s, single solder joint can save the time of 4-1.5=2.5s, have 6 according to the vehicle body of each car
The workload of solder joint, annual 50000 production plans, can save working hour 2.5*6*50000=750000S every year.
Fig. 6 is a kind of partial structural diagram of another angle of puppet's welding mechanism provided in an embodiment of the present invention.Such as Fig. 6
Shown, illustratively, second electrode connection component 9 can also include cable connection block 5b.Cable connection block 5b is located at the second electricity
Between pole 5 and the second cylinder 10, cable connection block 5b is in a strip shape.When need by cable 16 connect second conduction copper bar 14 (see
When Fig. 1) with second electrode 5, it is connect by the cable connection block 5b of strip with cable 16, cable 16 can be made far from second electrode
5, it avoids cable 16 and clamp positioning mechanism from being formed and interferes.
The course of work of puppet's welding mechanism provided in an embodiment of the present invention is simply introduced below with reference to FIG. 1 to FIG. 6.Including such as
Lower step:
Bodywork parts are placed on station by the first step, pass through soldering cramping apparatus positioning mechanism Set and Positioning；
Second step operates the first cylinder 4, and coordination electrode swing arm 2 is turned to the welding position of bodywork parts, in switching process
In, if be connected with first electrode 3 first electrode connection component 2a and soldering cramping apparatus positioning mechanism formed interfere, by this first
Electrode connection component 2a is removed, and is again installed to first electrode connection component 2a after electrode swing arm 2 is moved to welding position
In electrode swing arm 2, first electrode 3 is made to be directed at corresponding solder joint on welding position；
Second electrode 5 is moved to the welding position of bodywork parts by third step, is prolonging second electrode 5 with first electrode 3
It stretches and is in a straight line on direction；
4th step welds bodywork parts by first electrode 3 and second electrode 5.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
