Abstract
The utility model relates to an automatic angle-welding gun for the inner hole of a pipe and a pipe plate, comprising a welding gun matrix and a gun head. The welding gun matrix can have a structure corresponding to the automatic welding gun of the prior art, the structure of the gun head comprises a copper shaft, a copper core and a tungsten electrode, and the copper shaft is a hollow structure. The essential technical characteristic is that the copper core is a hollow structure and is connected with the tag end of the copper shaft, and an insulation protection mouth is arranged at the periphery of the copper core. The tungsten electrode is aslant installed on the copper core and passes through the insulation protection mouth, and air outlet holes are distributed around the tungsten electrode on the copper core. Open holes are arranged at the periphery of the tungsten electrode on the protection mouth, and a positioning sleeve is arranged on the copper shaft. The utility model has artful structure and successfully solves the problem of welding the angle of a small diameter in the inner hole of the pipe and the pipe plate.
Description
The utility model belongs to the welding gun of automatic welding usefulness, particularly a kind of pipe, the automatic fillet welding welding gun of tube sheet endoporus.
At present, pipe, tube sheet endoporus weld automatically and are divided into fillet welding and butt welding two classes both at home and abroad, for larger-diameter endoporus welding, no matter be that butt welding or fillet welding all have corresponding welding gun to realize.The welding gun structure of minor diameter endoporus butt welding adopts ceramic structure in the world, but the fillet welding welding gun structure of minor diameter (particularly 38mm is following) endoporus is not appeared in the newspapers.The petrochemical plant heat exchanger of some special defectss can only adapt to the mode of outside weldings because of adopting the endoporus welded corner joint, causes device structure unreasonable, and service life is short.
The purpose of this utility model provides a kind of pipe, the automatic fillet welding welding gun of tube sheet endoporus, and this welding gun delicate structure, and easy to use, this welding gun is adapted to the fillet welding of minor diameter endoporus especially.
Another purpose of the present utility model provides the rifle head of above-mentioned pipe, the automatic fillet welding welding gun of tube sheet endoporus.
Pipe of the present utility model, the automatic fillet welding welding gun of tube sheet endoporus; comprise welding gun parent, rifle head; the welding gun parent comprises driving mechanism, welding wiring; the rifle head comprises copper axle, copper core, tungsten electrode; the copper axle is that hollow-core construction links to each other with welding wiring, driving mechanism; it is characterized in that the copper core is that hollow-core construction is connected the copper shaft end; copper core periphery is the insulation protection mouth; the tungsten electrode bevel is installed on the copper core and passes the insulation protection mouth; being distributed with venthole around the tungsten electrode on the copper core, is bigger perforate in the tungsten electrode periphery on the insulation protection mouth.
On above-mentioned copper axle, have positioning sleeve, welding gun is located in tubesheet holes, prevent that welding gun from rocking.
The angle α of tungsten electrode and between centers is preferably 15～75 degree angles.
Improvements of the present utility model are the architecture advances of rifle head, and to adapt to the fillet welding of minor diameter endoporus, the welding gun parent can be the corresponding structure of prior art automatic welding gun, for the rifle head provides protection gas, conducting welding current, drives rifle head rotation etc.The welding wiring comprises welding control electric wire, air inlet pipe, water inlet pipe.The rifle header structure as mentioned above; comprise copper axle, copper core, tungsten electrode; the copper axle is a hollow-core construction; the major technique characteristics are that the copper core is a hollow-core construction; be connected the copper shaft end, copper core periphery is the insulation protection mouth, and the tungsten electrode bevel is installed on the copper core and passes the insulation protection mouth; being distributed with venthole on the copper core around the tungsten electrode, is bigger perforate in the tungsten electrode periphery on the protection mouth.
Have positioning sleeve on the copper axle, play the role of positioning.The angle α of tungsten electrode and between centers is preferably 15～75 degree angles.
Below in conjunction with the embodiment description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a rifle head part structural representation;
Fig. 3 is the utility model user mode reference diagram;
Among the figure: 1 welding wiring, 2 welding gun parents, 3 positioning tubes, 4,6 positioning sleeves, 5 bronze medal axles, 7 bronze medal cores, 8 tungsten electrodes, 9 pottery protection mouths, 10 water inlet pipes, 11 outlet pipes, 12 air inlet pipe 13, fixing 17 sleeves, 18 tube sheets, 19 pipe of venthole 14 holes 15 screws, 16 bronze medal cores
Welding gun is made up of welding gun parent 2 and rifle head, and the welding gun parent is the prior art structure, and it grips mechanism as hand simultaneously, and micro machine is housed in the parent, and the rotation of motor drives the rotation of arc welding gun head, finishes the welding of whole circle.Water inlet pipe 10, air inlet pipe 12 and welding control electric wire are inserted by welding wiring 1, and welding control electric wire links to each other with automatic welder(welding machine), and water inlet, water outlet are the heats that is transmitted by the rifle head in order to cool off.The same prior art of above-mentioned detailed operation process.
The rifle head comprises copper axle 5, copper core 7, tungsten electrode 8, pottery protection mouth 9, positioning sleeve 4, positioning sleeve 6; tungsten electrode 8 is fixed on the copper core 7 by screw 15; and pass pottery and protect mouth 9 (insulation protection mouth); the angle α of tungsten electrode and copper axle is 15～75 degree angles; fixing 16 in copper core and the soldering of copper core are fixed, and its end is that slotted hole cooperates the mutual rotation that prevents between copper core and the pottery protection mouth with pottery protection mouth.Being distributed with inclined hole on copper core one side around tungsten electrode is venthole 13, is a bigger perforate 14 around tungsten electrode on the pottery protection mouth 9, and positioning sleeve 4,6 is stuck on the sleeve 17, and the other end of positioning sleeve 6 is stuck on the pottery protection mouth.
Advantage of the present utility model:
Delicate structure has successfully solved the problem, particularly diameter of bore of pipe, tube sheet endoporus medium-small diameter automatic fillet welding Fillet welding problem below 38 millimeters is used in combination with automatic welder(welding machine), is mainly used in special defects petrochemical plant heat exchanger and nuclear The endoporus fillet welding of equipment.
