Described air supply system comprises air feed box, connects the gas supply line of air feed box; Described air feed box one end is fixed on the end of rocking bar B, and the other end arranges a cavity.
Further, a by-pass valve control is installed in described gas supply line, and is fixed on the sidewall of car body.
Further, a pair vertical rail is installed at the two ends of described rocking bar A, and vertical rail bottom is welded on the upper surface of car body.
Further, the opposing sidewalls lower horizontal of described car body welds some nuts, and coordinates with some jackscrew grafting.
Further, the cavity side of described air feed box one end is wound around resistance to guncotton.
Further, in the cavity of described air feed box one end, a sieve plate is set.
Further, be plugged with stainless steel inside described sieve plate and cut son.
The invention has the advantages that:
1) gas shielded arc welding back of weld gas shield frock parts mostly are dismountable, strong adaptability, convenient, flexible, install, simple to operate, air feed box is by the adjustment of jackscrew and endplay device, add that spring force can be accomplished to fit tightly weldment to greatest extent, saving and protection gas and excellent effect;
2) by-pass valve control is installed in gas supply line, and is fixed on the sidewall of car body, convenient in close welding scene one end adjustment throughput;
3) a pair vertical rail is installed at the two ends of rocking bar A, and vertical rail bottom is welded on the upper surface of car body, can limit rocking bar double swerve and even depart from position while welding;
4) the opposing sidewalls lower horizontal of car body welds some nuts, and grafting coordinates some jackscrews, effectively can catch ground, is unlikely to slide, and can play the effect of levelling device;
5) air feed box one end cavity side is wound around resistance to guncotton, increases sealing and can protect weldment not by the scratch of air feed box simultaneously, when weldment is revolving body, then also needs to process binding face;
6) in the cavity of air feed box one end, a sieve plate is set, makes the full air feed box of protective gas energy uniform fold, being plugged with stainless steel inside sieve plate simultaneously and cutting son, for increasing gas flow resistance, making air feed even.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of gas shielded arc welding back of weld of the present invention gas shield frock.
Fig. 2 is the structural representation of the air feed box of a kind of gas shielded arc welding back of weld of the present invention gas shield frock.
Detailed description of the invention
As depicted in figs. 1 and 2, the invention discloses a kind of gas shielded arc welding back of weld gas shield frock, comprise connect successively motion, bindiny mechanism and air supply system.
The telescopic bar 1 that motion comprises car body 2, is arranged on the wheel 3 of car body 2 lower end and is arranged on car body sidewall; The opposing sidewalls lower horizontal of car body 2 welds some nuts 9, and coordinates with the grafting of some jackscrews 4.
Bindiny mechanism comprises rocking bar A7, rocking bar B11, bracing frame 15, spring 6 and guide rod 10; Rocking bar A7 one end is hinged on the upper end of 2, the other end and rocking bar B11 hinged, simultaneously a pair vertical rail 13 is installed at the two ends of rocking bar A7, and vertical rail 13 bottom is welded on the upper surface of car body 2; Bracing frame 15 horizontal welding is connected on the sidewall of car body 2, and is in the lower end of rocking bar A7, arranges a groove in the middle part of bracing frame 15; Guide rod 10 coordinates with spring 6 sleeve, and upper end thereof is bottom rocking bar A7, and lower end coordinates with groove grafting.
