Abstract
The invention discloses a carbon arc air gouging torch for a narrow gap. The carbon arc air gouging torch comprises a torch head, a torch body, an air inlet device and a conductive device. The torch head is formed by a hollow conductive rod and a nozzle fixedly arranged in the conductive rod. The torch body is of a hollow structure with the shape similar to an S, one end of the torch body is connected with the conductive rod in a welding mode, the other end of the torch body is connected with the air inlet device, the conductive device is arranged on the air inlet device in a sleeved mode, and the conductive device comprises a conductive clamp and a compression bolt used for compressing the conductive clamp. In the carbon arc air gouging torch, the torch body is small in diameter and is of the structure with the shape similar to the S, therefore, operation can be conducted in the narrow gap, and the working efficiency is improved. The nozzle is provided with a groove and a slit so that a carbon rod can be clamped conveniently. In addition, barbs are arranged on the air inlet device, and therefore the air inlet device cannot fall off after being connected with an air inlet pipe on an air compressor.
Description
Technical field
The invention belongs to carbon arc air gouging technical field, relate in particular to a kind of carbon arc gouging gun for narrow gap welding, be mainly used in compared with the reparation of narrow gap welding defect.
Background technology
Carbon arc gouging gun is a kind of instrument that simultaneously utilizes electric arc and high pressure air workpiece to be carried out to arc gouging, is that welder carries out all kinds of Steel Structure Weld back gougings, drives the requisite instruments such as " U " type groove.Traditional carbon arc gouging gun is large and heavy, and the work in some narrower gaps, just can not enter work, can barely use in time, can not guarantee well work quality, affects very much operating efficiency.
Summary of the invention
For overcoming traditional carbon arc gouging gun rifle body heaviness, the deficiency such as thick, the object of this invention is to provide a kind of carbon arc gouging gun for narrow gap, the rifle body of this carbon arc gouging gun is thin and be arcuate structure, is highly suitable for the planing work such as reparation of narrow gap welding defect.
In order to realize foregoing invention object, the present invention adopts technical scheme as described below:
A kind of carbon arc gouging gun for narrow gap, it comprises rifle head, rifle body, inlet duct and electric installation, rifle head is made up of the conducting rod of hollow and the nozzle being fixedly arranged in conducting rod, described rifle body is the hollow structure of approximate serpentine, one end of rifle body and conducting rod welding, the other end is connected with inlet duct, is arranged with electric installation on inlet duct, and electric installation comprises conductive clip and for compressing the hold-down bolt of conductive clip.
Further, described inlet duct is a hollow bushing, and the outer wall hypomere of sleeve pipe is provided with screw thread, and outer wall epimere is provided with hangnail.
Further, described nozzle is hollow cylinder structure, on the outer wall of cylinder, axially uniformly offer some the lines of rabbet joint along it, the sidewall of cylinder one end is divided into some equal portions by these some lines of rabbet joint, on the outer circumference surface of every a sidewall, axially all offer groove along it, the length of groove is identical with the length of cylinder, between described groove and conducting rod inwall, forms compressed air channel.
Further, the external diameter of described rifle body is 10 ~ 30cm.
Owing to adopting technique scheme, the present invention has following superiority:
Rifle body diameter in the present invention is less, and for approximate " S " type structure, is convenient to operate in narrower gap, has improved operating efficiency; On described nozzle, relate to groove and the line of rabbet joint, be convenient to clamp carbon-point; In addition, hangnail is set on inlet duct, after being connected with the air inlet pipe on air compressor, can prevents from coming off.

The specific embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of carbon arc gouging gun for narrow gap, it comprises rifle head, rifle body 3, inlet duct 4 and electric installation, rifle head is made up of the conducting rod 1 of hollow and the nozzle 2 being fixedly arranged in conducting rod, described rifle body 3 is the hollow structure of approximate serpentine, one end of rifle body 3 and conducting rod 1 weld, the other end is connected with inlet duct 4, between inlet duct 4 and rifle body 3 by being welded to connect, on inlet duct, be arranged with electric installation, electric installation comprises conductive clip 5 and for compressing the hold-down bolt 6 of conductive clip.
Described inlet duct 4 is a hollow bushing, and the outer wall hypomere of sleeve pipe is provided with screw thread, and outer wall epimere is provided with hangnail; Electric installation when mounted, is first set in conductive clip on the outer wall of sleeve pipe, then hold-down bolt is utilized the screw thread on sleeve pipe that conductive clip is compressed; In addition, inlet duct is after being connected with the air inlet pipe of air compressor, and described hangnail can prevent from coming off between inlet duct and air inlet pipe.
Described nozzle 2 is hollow cylinder structure, on the outer wall of cylinder along its axial uniform some lines of rabbet joint 9 that offer, the sidewall of cylinder one end is divided into some equal portions by these some lines of rabbet joint, on the outer circumference surface of every a sidewall, axially all offer groove 8 along it, the length of groove is identical with the length of cylinder, between described groove 8 and conducting rod 1 inwall, forms compressed air channel; The centre bore of nozzle 2 is used for installing carbon-point 7, and owing to offering the line of rabbet joint on nozzle 2 sidewalls, therefore this nozzle can be applicable to the operation of the carbon-point of multiple different-diameter size.
The external diameter of described rifle body 3 is 10 ~ 30cm, is convenient to the operation in narrow gap.
The present invention, in the time of concrete application, is connected inlet duct with the air inlet pipe of air compressor, in the centre bore of nozzle, installing carbon-point can use.
