Technical field
The utility model relates to the pipeline chucking devices, in particular to one on a kind of positioner for automatic welding device
Six dog chucks of kind.
Background technique
In the prior art, need a kind of fixture by different-diameter in pipe prefabrication factory, the positioner of automatic welding device
Pipe and flange, elbow part clamp, welded for automatic welder.Due to the flange diameter to match with same pipe
It changes greatly, therefore it is required that the adaptability of fixture extensively when in addition clamping flange will need that flange is positioned and reserves enough
Welding bead carries out welding for automatic welder to be prefabricated into various required pipe fittings.The inventor of present patent application sends out in practice
Existing, the fixture in this field is scroll chuck in the prior art.There are the following shortcomings for this kind of chuck: 1, Wu Fashi
The now reliable retention to the pipe of major diameter, flange or elbow and positioning.When especially clamping the flange of major diameter, it can only clamp
Outer circle or inner wall be easy to cause flange position inaccurate without reliable positioning surface, and chucking power not enough causes flange to loosen, askew
Tiltedly, to influence the quality of welding.2, the size range of existing fixture clamping pipe fitting is small, limits the use scope of equipment.
In conclusion lack in the prior art it is a kind of can pipe, flange or elbow to major diameter carry out reliable retention
And positioning, chucking power is stronger, the pipeline folder on the positioner for automatic welding device wider array of to plumbing dimensions adaptation range
Holding equipment.
Utility model content
The technical problems to be solved in the utility model be to provide it is a kind of can pipe, flange or elbow to major diameter into
Row reliable retention and positioning, chucking power is stronger, the six pawl cards for automatic welding device wider array of to plumbing dimensions adaptation range
Disk.
In order to solve the above technical problems, technical solution provided by the utility model are as follows: a kind of six dog chucks, it includes bottom
Seat, sets that there are three active deck and three auxiliary decks on the pedestal；Above-mentioned six decks are mutually staggered and are uniformly distributed
On pedestal, center bevel gear is equipped at the center of the pedestal；The active deck is equipped with drive bevel gear, described
Drive bevel gear on be connected with active screw rod, the active screw rod is equipped with nut, and one end of active screw rod stretches out in master
Except dynamic deck；Drive bevel gear on three active decks is engaged with center bevel gear；The auxiliary deck
On paranema bar is installed, one end of paranema bar stretches out in except auxiliary deck, and the paranema bar is equipped with nut；It is above-mentioned each
A claw is fixedly connected on nut；Sliding rail corresponding with claw is respectively equipped on six decks；The card
Pawl is integrally in the L-type to couch, is equipped with a projection, the projection and claw towards the side of center bevel gear on claw
One is formed between main body for being clamped the notch of flange.
Preferably, being equipped with a groove backwards to the side of center bevel gear on the claw.
Preferably, in addition to groove, being additionally provided with two rows of cards on the side of center bevel gear on the claw
Tooth.
Preferably, being equipped with V-groove among two rows of latches.
Preferably, the projection is equipped with latch.
After adopting the above structure, the utility model has the following beneficial effects: six dog chucks of present patent application design can
It is applicable in the flange of diameter of different sizes, it is applied widely.Six dog chucks are by pedestal, active deck, auxiliary deck, center umbrella tooth
The composition such as wheel, transmission umbrella wheel, active screw rod, paranema bar and nut, sliding rail, claw, rotation active screw rod make drive bevel gear band
Center bevel gear is moved to make other active screw rod while rotate to drive nut and the mobile clamping workpiece of claw, difference revolute pair
Screw rod drives nut and jaws clamp.Keep Workpiece clamping reliable.Simultaneously because claw is designed with the special of notch
L shape, flange be placed in notch position when clamping flange, then fix to improve with adjustment cushion block and jackscrew and clamp flange
Stability positions workpiece in fixture reliably.In addition claw positive and negative can use, and expand the scope of application of fixture.
In conclusion the utility model provide it is a kind of can pipe, flange or elbow to major diameter reliably pressed from both sides
It holds and positions, chucking power is stronger, six dog chucks for automatic welding device wider array of to plumbing dimensions adaptation range.
