Abstract

The utility model relates to an argon arc welding automatic welding blow lamp for a contacting generating arc, which is characterized in that the distance of the tungsten electrode and the workpiece is adjustable; the adjustable portion is composed of the tungsten electrode, a locking and clamping head which is sheathed with the tungsten electrode, a sleeve cylinder which is connected with the locking and clamping head and is sheathed on the external side of the tungsten electrode, a regulating spring which is clamped between the boss of the sleeve cylinder and adjusting screws, and a button shaft which is provided with a button cap. The lower plane of the boss of the argon arc welding automatic welding blow lamp for a contacting generating arc can mutually press with the upper plane of the boss of the sleeve cylinder. The locking portion is composed of a press cover which is loosely sheathed on the external sides of the button shaft and the sleeve cylinder and is connected with the adjusting screws, a press cap which is sheathed on the locking portion, and a lower connecting component which is provided with an air inlet and is tightly sheathed with the tungsten electrode with the lower end. The lower part of the former is connected with the welding blow lamp; the upper part of the argon arc welding automatic welding blow lamp for a contacting generating arc and the press cover are totally connected with the conductive body of the welding blow lamp, and the gun body which is provided with the connecting component of the upper gun body and the connecting component of the lower gun body is tightly sheathed with the conductive body of the welding blow lamp.

Description

Argon arc welding automatic welding blow lamp for contacting generating arc

The argon arc welding mechanical blowpipe that a kind of contacting ignition arc is used belongs to the welding equipment annex and makes the field.

When common argon-arc torch is done the contacting ignition arc operation under the condition of thin part high-quality automatic butt weldering, because welding torch is to be fixed on the frame of automatic walking and will to keep certain arc length when welding, thereby just can't realize, because the spacing between its tungsten electrode and workpiece can't be adjusted in real time.

The purpose of this utility model is to provide a kind of argon arc welding mechanical blowpipe that can realize contacting ignition arc when approaching the automatic butt welding of part high-quality.

Of the present utility model being characterised in that: but its argon arc welding mechanical blowpipe that to be the push type contacting ignition arc of spacing between a kind of manual adjustments tungsten electrode and workpiece use, its manual adjustments partly contains tungsten electrode 1, be enclosed within the prong type tungsten electrode locking chuck 2 on the tungsten electrode 1, be enclosed within the tungsten electrode sleeve 3 that tungsten electrode 1 is outer and the lower end is connected with tungsten electrode locking chuck 2 internal threads, be enclosed within the outer and regulating spring 4 that push up mutually with its boss lower plane of tungsten electrode sleeve 3, the spring set screw 5 of pushing up mutually with latter other end and upper end tightly are with button cap 6 and the push button shaft 7 that presses mutually on the plane on the boss of plane and tungsten electrode sleeve 3 on its boss, its lock portion is enclosed within the gland 8 that push button shaft 7 and tungsten electrode sleeve 3 are outer and its lower end connects with spring set screw 5 internal threads by pine, tightly be enclosed within its outer pressure cap 9 and be enclosed within tungsten electrode 1 and tungsten electrode sleeve 3 is outer and the lower end has an air inlet following connector 10 constitutes, welding torch 11 and following connector 10, welding torch electric conductor 12 and gland 8, following connector 10 all is threaded, its rifle body portion is by tightly being enclosed within the outer rifle body 13 of welding torch electric conductor 12 and respectively at last, following two ends and rifle body 13 fasten mutually on, lower gun body connector 14,15 constitute, at

gland

8 and 14 of upper cutting gun connectors sealing ring 16 is arranged, its longitudinal section is asked for an interview Fig. 1.

Use proof: it can realize contacting ignition arc easily when the argonaut welding of thin plate high-quality.

In order in conjunction with the embodiments the utility model to be done detailed describing below, show as follows employed accompanying drawing number of the utility model application documents and title brief introduction:

Fig. 1: the argon arc welding mechanical blowpipe longitudinal section that contacting ignition arc is used.

Embodiment:

Ask for an interview Fig. 1.Wherein descend connector 10 lower ends to have four air admission holes altogether.It can be according to different tungsten electrode locking chuck of the diameter adapted of different tungsten electrode 12 and following connector 10.

When argonaut welding, after connecting power supply, flicking is button cap 6 once, and it just makes tungsten electrode send for 1 time and contacts gently with workpiece, forms short circuit, gives heated parts under the steady-state shortcircuit current effect of putting at welding machine.When openhanded opening, then tungsten electrode 1 just pops up automatically, resets under the effect of regulating spring 4, return to original tungsten electrode of determining 1 and the distance between the workpiece, electric arc ignites rapidly under the good dynamic characteristic effect of contravariant arc welding power source, frame just drives welding torch 11 and moves along welding direction after time-delay, implement welding automatically.

Claims

1, the argon arc welding mechanical blowpipe that a kind of contacting ignition arc is used, it contains the rifle body, tungsten electrode, the welding torch electric conductor, nozzle and corresponding locking member, it is characterized in that: but it be between a kind of manual adjustments tungsten electrode and workpiece spacing apply the argon arc welding mechanical blowpipe that the pressure type contacting ignition arc is used, its manual adjustments partly contains tungsten electrode (1), be enclosed within the prong type tungsten electrode locking chuck (2) on the tungsten electrode (1), be enclosed within the tungsten electrode sleeve (3) that tungsten electrode (1) is outer and the lower end is connected with tungsten electrode locking chuck (2) internal thread, be enclosed within the outer and regulating spring (4) that push up mutually with its boss lower plane of tungsten electrode sleeve (3), the spring set screw (5) of pushing up mutually with latter other end and upper end tightly are with button cap (6) and the push button shaft (7) that presses mutually on the plane on the boss of plane and tungsten electrode sleeve (3) on its boss, its lock portion is enclosed within the gland (8) that push button shaft (7) and tungsten electrode sleeve (3) are outer and its lower end connects with spring set screw (5) internal thread by pine, tightly be enclosed within its outer pressure cap (9) and be enclosed within tungsten electrode (1) and tungsten electrode sleeve (3) is outer and the lower end has following connector (10) formation of air inlet, welding torch (11) and following connector (10), welding torch electric conductor (12) and gland (8), following connector (10) all is threaded, the rifle body portion is by tightly being enclosed within the outer rifle body (13) of welding torch electric conductor (12) and respectively at last, following two ends and rifle body (13) fasten mutually on, lower gun body connector (14), (15) constitute, between gland (8) and upper cutting gun connector (14), sealing ring (16) is arranged.
