Abstract
The utility model discloses a deep-drilling exterior-angle automatic welding gun, comprising a tungsten electrode, a current-carrying cable, gun rod, a centering device and a driving device. The utility model is mainly characterized in that a four-link mechanism is arranged between the gun rod and a gun nozzle body which is connected with the tungsten electrode, that the centering shaft of the centering device is positioned on the front end of the gun rod, that the centering shaft is provided with a centering sleeve, and that an arc voltage adjustment mechanism is composed of a pull rod, a pull rod handle and adjusting nuts. The utility model, which is suitable for self-fusion welding of deep-drilling pipes and pipe plates, can carry out high-quality welding of intensity welding seams and sealing welding seams.
Description
The utility model relates to a kind of soldering appliance, particularly relates to a kind of deep hole exterior angle automatic welding gun.
Manual welding can only be finished more shallow eyelet welding and connect, can't finish the outer welded corner joint of dark endoporus, in recent years existing abroad deep hole exterior angle welding gun, the PIA/POB welding gun of Sweden ESAB company for example, its fillet welding only can be tilted about 0～10 ° with downhand welding, can only realize inside fillet, its welding point form also is confined to spill, and its centring means adopts steel ball centering, is difficult for extracting out when mouth of pipe penetration, this apparatus structure complexity, the manufacturing cost height.
The purpose of this utility model is, provides a kind of simple in structure, and cost of manufacture is low, can finish the automatic welding gun of the outer welded corner joint of deep hole.
The utility model can be realized with following mode:
Welding gun is formed and is comprised tungsten electrode, current carring cable, barral of a gun, centring means and drive unit, its architectural feature is, between rifle mouth body that connects tungsten electrode and current carring cable and barral of a gun, four-link mechanism is set, centring means is made up of centration axis and centring sleeve, and centration axis places the front end of barral of a gun, and centring sleeve is placed on the centration axis, and it is rotatable, adjusting nut is arranged on the gun barrel, and pull bar one end links to each other with pole, and the other end links to each other with the pull bar handle.
Centring sleeve is the middle bloated folder formula structure that groove is arranged.
Also be provided with gas hood on the tungsten electrode.
Advantage of the present utility model:
Current-carrying capacity of cable is big, welding current is at 8～200A, heat-resisting quantity is good, and operating temperature can reach 80～150 ℃, and can finish internal orifice dimension is 25～35mm, the degree of depth is that weld automatically at the deep hole exterior angle of 250～300mm, its welding quality can guarantee to rotate flexibly in the intensity weldering of 0.4Pa and general seal weld, and the fillet welding angle can tilt 25～30 ° with workpiece, the centring sleeve of the bloated folder formula structure of its elasticity makes and welds easily extraction welding gun of back.
Fig. 1 is the utility model overall structure schematic diagram.
The utility model is described in further detail below in conjunction with accompanying drawing:
Current carring cable 4 one ends of automatic welding gun link to each other with tungsten electrode 1 through rifle mouth body 3, also be covered with gas hood on the tungsten electrode 1, gas hood 2 is by ceramic nozzle and divide air sifter to form, current carring cable 4 other ends are connected on the pneumoelectric interface 6 in the drive unit 7, drive motors 16 and reducing gear also are installed in the drive unit 7, motor 16 is the stepper motors that have speed measuring device, pull bar 9 one ends link to each other with pole 10, the other end links to each other with pull bar handle 8, pull bar 9 can move in gun barrel 15, pull bar 9, pull bar handle 8 and adjusting nut 5 are formed the arc voltage guiding mechanism, pole 10 and connecting rod 11 are controlled opening of tungsten electrodes 1 or are tightened up, during use, earlier move pull bar handle 8 arrow indication right in figure to stop position, pull bar 9, pole 10 and connecting rod 11 tighten up the welding gun soldering tip, then the welding gun soldering tip is put in fabrication hole, centring sleeve 14 enters treats welded tube, adjusting nut 5 precession fabrication holes, regulate welding gun position in bobbin carriage, be fixed up then, dropped into user mode, again with pull bar handle 8 to arrow indication left to moving stop position to, connecting rod 10 and pole 11 are opened soldering tip, the open radius of gyration can be adjusted by changing pole 11, soldering tip and workpiece angle of inclination 25～30 ° adjustable, the distance of tungsten electrode 1 and tube sheet is except with the adjustment of tungsten electrode adjustment nut, also be fixed up after mixing up in the position of compensation linkage handle 8 on gun barrel 15.
Centring sleeve 14 is middle axially grooved bloated cassette structures, is convenient to welding gun and inserts and extract out welded tube, and pole 10, connecting rod 11 adopt insulating materials to make, and current carring cable 4 adopts alloy annealed copper wire strands to form current carring cable 4 overcoat nylon hoses, anti-high frequency, high pressure.
