7. the welding method of boxing TIG weld equipment described according to claim 1 ~ any one of 6, it is characterised in that: it is wrapped
Include following steps:
S1, tamponade will be pressed into the hole of the left end of guide pipe (50)；Guide pipe (50) is supported on directive wheel；
S2, the tamponade in guide pipe (50) is sequentially passed through to the second connecting tube (36), the first connecting tube (35), hole E(30), expansion set
Cylinder (33), bellmouth (28), hole B(24), hole A(23), closed chamber (6) finally tamponade is pressed in circular pit (15), from
And realize the positioning of guide pipe and tamponade；
The clamping of S3, guide pipe: control cylinder (16) piston rod stretches out, and piston rod drives long connecting rod (17) to move upwards, long to connect
Bar (17) drives the second connecting tube (36) to move downward, and the second connecting tube (36) drives the first connecting tube (35) to move downward, the
One connecting tube (35) drive movable axis move downward, spring (32) is gradually compressed, movable axis during moving downward, due to
Bellmouth (28) is matched with wedge block (31), and wedge block (31) is promoted gradually to move upwards, when expansion set cylinder (33) are located at wedge shape
When block (31) is moved to above wedge block (31), wedge block (31) radially holds expansion set cylinder (33) tightly, and then makes expansion set cylinder
(33) guide pipe (50) are embraced, the clamping of guide pipe is finally realized；
The rotation of S4, guide pipe: opening motor (2), and motor (2) drives driving gear rotation, and driving gear drives driven gear
(22) it rotates, driven gear (22) drives rotary sleeve (21) rotation, since guide pipe is limited by movable axis, guide pipe
Synchronous rotary, to realize the rotation of guide pipe；
The adjustment of S5, tungsten electrode and annulus position, it includes that tungsten electrode horizontal direction adjusts, tungsten electrode front-rear direction adjusts, on tungsten electrode
Lower direction adjustment；
The step of tungsten electrode horizontal direction adjusts are as follows: unscrew two adjusting screws (49) of level, at this time the chassis of T shape column (39)
It can be moved horizontally in type chamber (44), when tungsten electrode (43) is adjusted to the surface of annulus, tighten two adjusting screws of level
(49), so as to adjust the position of tungsten electrode horizontal direction；
The step of tungsten electrode front-rear direction adjusts are as follows: unscrew former and later two and adjust screw (49), at this time the chassis of T shape column (39)
It can be moved forward and backward in type chamber (44), when tungsten electrode (43) is adjusted to the surface of annulus, tighten former and later two and adjust screw
(49), so as to adjust tungsten electrode position in the front-back direction；
The step of tungsten electrode up and down direction adjusts are as follows: rotation thread bush (41), thread bush (41) do axis on external screw thread B(47)
To movement, adjusting rod (38) is made to axially move along pilot hole, when tungsten electrode (43) is adjusted to the surface of annulus, tightens lock
Tight screw (48), so as to adjust the position of tungsten electrode up and down direction；
S6, plug (52) are opened, is passed through helium in closed chamber (6) through stomata (51), after filling a period of time, close plug
(52)；
The welding of S7, annulus, power supply (10) is powered to tungsten electrode (43), between tungsten electrode (43) and guide pipe (50) and tamponade
Electric arc is generated, arc-melting material can along the circumferential direction carry out arc welding, work as guiding with the rotary motion of guide pipe
It can be by annular seam welding after one circle of pipe rotation；
S8, after welding product taking-up, control cylinder (16) piston rod retract, piston rod drive long connecting rod (17) downwards transport
Dynamic, the second connecting tube (36) moves right at this time, and the second connecting tube (36) drives the first connecting tube (35) to move right, and first connects
Adapter tube (35) drives movable axis to move right, while under the restoring force of spring (32), further increases movable axis pushing away to the right
Power promotes expansion set cylinder (33) to move right, and wedge block (31) is separated with guide pipe (50) at this time, and wedge block (31) is no longer held tightly and led
Xiang Guan at this time can take out the product after welding.
