Abstract
The utility model relates to a connection device of a spray nozzle and a protection sleeve for a welding torch, belonging to the technical field of the welding torch structure of inert gas or mixed gas protected melting pole automatic welding equipment. The connection device is mainly characterized in that a conducting nozzle is sleeved in the spray nozzle; the protective sleeve is sleeved in the outer layer of a conducting pole; a cap nut is sleeved on the protection sleeve; the rear part of the cap nut supports against the lug boss of the protection sleeve; and the internal threads of the cap nut are fixedly connected with the external threads of the spray nozzle. The utility model has the advantages that the cap nut is in threaded connection with the spray nozzle, and the joint surface of the cap nut and the spray nozzle is well jointed so that air can not enter the welding torch from gaps in the joint surface; and in addition, because the cap nut is in threaded connection with the spray nozzle, the cap nut can be screwed down, and the spray nozzle can be assembled and disassembled rapidly and conveniently without being obstructed and interfered by pipes, wires and other auxiliaries.
Description
Technical field
The utility model relates to inert gas or mixed gas protected consumable electrode automatic welding and connects welding torch technical field in the equipment.
Background technology
Automatic welding torch is that a kind of inert gas or mixed gas protected consumable electrode automatic welding connect the welding torch in the equipment, uses rated current more than 1000A.After protective gas enters welding torch by rectification chamber (air chamber),,, thereby form inert gas or the mixed gas protected district isolated with air in the welding pool region surface finally by the nozzle ejection via current divider, protective sleeve.
Connecting between existing automatic welding torch nozzle and the protective sleeve is to adopt the suit snap fit, and the faying face of nozzle and protective sleeve leaves the slit, and air enters welding torch inside from the slit, reduced the quality of welding protection gas.
The utility model content
The utility model provides a kind of automatic welding torch, and cap nut and nozzle faying face are fitted good, and easy accessibility has improved the quality of weld seam protection gas.
The utility model is that this bar is realized: the welding torch coupling arrangement of protective sleeve and nozzle, comprise nozzle 1, cap nut 2 and protective sleeve 3, ignition tip 4 is sleeved in the nozzle 1, protective sleeve 3 is sleeved on the skin of conducting rod 5, the major technique feature is: cap nut 2 is sleeved on the protective sleeve 3, and the boss of protective sleeve 3 is withstood at the rear portion of cap nut 2; The external screw thread of the internal thread of cap nut 2 and nozzle 1 is connected and fixed.
Compared with prior art, the beneficial effects of the utility model are: cap nut connects with nozzle threads, and cap nut and nozzle faying face are fitted good, and air can not enter welding torch inside from this slit; The cap nut formula connects in addition, does not need rotary nozzle to screw, and both dismounting was quick and convenient, has avoided the obstruction and the interference of annexes such as other pipeline, electric wire in the process of dismounting nozzle again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the welding torch coupling arrangement of protective sleeve and nozzle, comprise nozzle 1, cap nut 2 and protective sleeve 3, ignition tip 4 is sleeved in the nozzle 1, protective sleeve 3 is sleeved on the skin of conducting rod 5, structure is: cap nut 2 is sleeved on the protective sleeve 3, and the boss of protective sleeve 3 is withstood at the rear portion of cap nut 2; The external screw thread of the internal thread of cap nut 2 and nozzle 1 is connected and fixed.
The utility model uses in consumable electrode automatic welding connects welding torch in the equipment; the structure of consumable electrode automatic welding torch is; ignition tip is sleeved in the nozzle; conducting rod withstands the rear portion of ignition tip, and protective sleeve is sleeved on the skin of conducting rod, and the rear portion of current divider is fixed with insulation sleeve; the rectification chamber is fixed on the insulation sleeve rear portion; be provided with air inlet pipe on top, rectification chamber, rectification chamber afterbody is provided with into fiber tube, is set with fixed bar in advancing fiber tube.
