Abstract
The utility model discloses a welding gun nozzle structure, and aims to provide a welding gun nozzle structure with good security, stable welding positioning during operation, reasonable viewing angle and guaranteed welding quality. The welding gun nozzle structure comprises a nozzle body and a nozzle head, wherein a clamping slot used for clamping a welding wire is formed in the nozzle head; a protection cover in threaded connection is arranged on the nozzle body; a mirror groove is formed in the protection cover; one end of the mirror groove is aligned with the outer surface of the protection cover, and the other end of the mirror groove protrudes from the protection cover; the aligned end of the mirror groove is hinged to an observation mirror; the protruding end of the mirror groove is provided with multiple positioning grooves for clamping the observation mirror; a rigid support bar is arranged on one side, away from the mirror groove, of the protection cover; the support bar is connected with a pressing roller through a spring and a bracket; the pressing roller and the bracket are connected rotationally. The welding gun nozzle structure has the beneficial effects that the welding positioning stability is good, the welding quality is guaranteed, sparks and the wire are not easy to splash, and the safety is high.
Description
Technical field
The utility model belongs to welder field, relates in particular to a kind of welding gun mouth structure.
Background technology
In automobile making, we often need to use welding gun and carry out gas shielded arc welding in finished car, semi-finished vehicles, be used for repair, improve all parts.In the time that we carry out weld job on automobile top or side elevation, spark, the welding wire producing in the operation process interior trim of fit on of easy scaling loss that splashes threatens the personnel of reprocessing simultaneously; Moreover, in when welding, because welding wire length is changing always, be unfavorable for controlling rifle corners of the mouth degree and adjust in time face shield and carry out the observation of reasonable angle, easily cause that welding position is offset, welding quality is not high.
Chinese patent Granted publication number: CN202511281U, October 31 2012 Granted publication day, disclose a kind of torch head, described a kind of torch head comprises: gas input passage and gas output channel, gas input passage and gas output channel are communicated with by bent passage.The noise having produced when this torch head has reduced welding, has improved torch head comfort level in use, and then provides a kind of comfortable working environment for operator.The weak point of this utility model is, protection is limited, and security threat is large, can not effectively help operator to adjust in time viewing angle and welding wire location is unstable when welding, causes welding position to be departed from and not prison welding is leaned on.
Utility model content
The utility model is the deficiency that has defect in order to overcome the security of prior art welding rifle mouth, operational stability, provides a kind of security good, welds position stability high when operation, and viewing angle is reasonable, the welding gun mouth structure that welding quality is secure.
To achieve these goals, the utility model is by the following technical solutions:
A kind of welding gun mouth structure, comprise mouth body, mouth, described mouth is provided with the draw-in groove for clamping welding wire, described mouth is provided with the protective cover being threaded with mouth body with it, described protective cover is provided with mirror groove, align with protective cover outer surface in described mirror groove one end, outside the outstanding protective cover outer surface of the other end, alignment end and a peephole of mirror groove are hinged, jag is provided with some for blocking the locating slot of peephole, on described protective cover, be relatively provided with the support bar of rigidity away from a side of mirror groove, described support bar is connected with a pinch roller by spring and support, pinch roller and support are rotationally connected.Protective cover is for preventing splashing of spark, after welding wire length reduces to a certain degree, can press down peephole makes it snap in next locating slot, make within operator is in suitable scope all the time to the viewing angle at the wire welding place of connecing, improve the monitoring power to welding process, pinch roller can be pressed in position suitable on vehicle body simultaneously, improve supportive, allow user not change hands and tremble and can maintain welding wire position all the time near weld, the existence of spring can realize quick adaptation and regulate, even if ensure that welding wire length is changing always, user also can effectively control by the variation of the application of force on hand the position of welding wire, maintain the stable of welding process, ensure the quality of products.
As preferably, described protective cover is provided with some baulk rings, described baulk ring on protective cover madial wall, described baulk ring section semicircular in shape.Can prevent that first the high temperature welding wire splashing in protective cover from directly dropping and hurting sb.'s feelings, second can make to protect the inert gas of use to be blocked, form multiple interior circulation among a small circle, extend action time, improve protection effect.
As preferably, described protective cover is formed slopely a striker plate near a side direction inner side of support bar, and described striker plate is parallel with protective cover axis.Striker plate can be assisted and be caught the high temperature welding wire falling, and makes it can not directly splash the person upper, prevents that spark from spilling and hurt operator's pin downwards simultaneously.
The beneficial effects of the utility model are: welding position stability is good, and welding quality is protected, and spark, welding wire are difficult for splashing, safe.
