Description
Technical field
The present invention relates to welding mouth of pipe school sired results dress, belong to material shaping automation technical field.
Background technology
Ship pipeline differs in size as the blood vessels on human body, different, extends in all direction, crisscross, spreads all over
The complete each corner of ship, its task is the daily life needs for ensureing ship normal/cruise and meeting crewman, its act on and
Residing status is particularly significant.Ship piping system will select suitable size and the steel pipe system of thickness according to different pressure and flow
Make, the small latus rectum of normal conditions be less than DN550 can use it is seamless, more than DN350 can use welded still pipe make.For welding
The mode of steel pipe generally use longitudinal seam welding, weld seam is parallel with tube length direction, and after welding, the pipe both ends mouth of pipe can be carried out
School circle processing, the out-of-roundness of the usual production tube mouth of pipe are less than 2mm.When Relations Pertaining to ships makes, the length of pipe be not it is fixed,
Jacking processing would generally be carried out to the pipe of same specification different length, i.e., (country is usually in the steel pipe of a full-length
12 meters) on cut out the different pipe of length as required.Steel pipe after cutting often occurs that the both ends mouth of pipe loses showing for circle
As, and the out-of-roundness of the mouth of pipe is more than 2mm, even up to 6~7mm.Generally there is steel pipe-joint welding method as needed in ship piping system
The form such as orchid, steel pipe-W.N flange, steel pipe-steel pipe, the form of steel pipe-slip-on flange need steel pipe to be inserted into flange endoporus
Welding, so just has required precision to the size of outer diameter of steel pipes and flange endoporus, and main is exactly to have to want to steel pipe nozzle out-of-roundness
Ask, usually require that out-of-roundness is less than 2mm, just can guarantee that steel pipe smoothly inserts flange and can guarantee that and protected between steel pipe and flange
Rational, uniform gap is held, and rationally uniform gap using automatic welding means for being had very important significance.
On the other hand, the form of steel pipe-W.N flange and steel pipe-steel pipe is directed primarily to the unfitness of butt joint of butt joint, due to steel pipe
Mouth out-of-roundness is excessive, causes the unfitness of butt joint of butt joint excessive, it is impossible to meet requirement.
In order to solve to weld the situation that out-of-roundness is overproof after the mouth of pipe is cut, carried out when in school, pipe operates usually using jack
Hold round processing, i.e., before the pipe of school, jack be put into steel pipe nozzle, find the maximum place of deflection, carry out it is internal outward
Hold round, then flange is set on steel pipe, the gap of flange and steel pipe is adjusted when carrying out school pipe, gap uniformity is met to require
Place first carry out spot welding, then pull down jack, be put into the excessive place in gap, hold round again to gap it is suitable when spot welding,
So repeatedly untill steel pipe and the whole ring gap of flange are all uniform.So operate, although can meet to require, exist several
Problem is than more prominent, and first, the jack used is screw jack, and all-steel, kerb weight is overweight, operation inconvenience, worker
Labor intensity is larger, and security is not high.Second, it is cumbersome, need being dismounted for multiple times during holding round, efficiency is low.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of welding mouth of pipe school sired results dress,

Technical scheme：To achieve the above object, welding mouth of pipe school sired results dress of the invention, including fixed block, in fixed block
Four bases are circumferentially installed, base rod is interior to be provided with cushion block inserted with motion bar, one end of motion bar, and the other end is provided with ear muff,
Guide groove is provided with base, ear muff is slided along guide groove, and ear muff is hinged with strut, and the strut other end is hinged with four paws nut,
On screw mandrel, screw mandrel is arranged on fixed block four paws nut sleeve；By rotary screw rod, four paws nut is driven to be moved on screw mandrel,
So as to drive strut to move, strut drives motion bar elongation, and so as to withstand round tube inner wall, school circle is carried out to pipe.
Preferably, the ear muff is arranged on strut by screw bolt and nut, strut passes through screw bolt and nut and four paws
Nut connects.
Preferably, the motion bar includes the first motion bar and the second motion bar, the first motion bar is hollow-core construction, the
Two motion bars are inserted in the first motion bar, and cushion block is located at the second movable boom end, if being evenly distributed with the second motion bar
Dry pin-and-hole, is provided with through hole on the first motion bar, and pin is inserted from through hole, and pin is inserted into pin-and-hole, is moved so as to adjust cushion block
Dynamic distance is with treating that the internal diameter of school round steel pipe matches.
Preferably, the top of the cushion block is provided with seam.
Preferably, the pressing plate for preventing screw mandrel from coming off is installed on the fixed block.
Beneficial effect：The welding mouth of pipe school sired results dress of the present invention, is made, total quality is small, is easy to using high strength alumin ium alloy
Mobile and operation；By the way of four paws linkage, school circle efficiency high；The the second motion bar positioning hole customized according to pipe diameter is protected
The precision of school circle is demonstrate,proved, a set of school sired results dress is adapted to the steel pipe school circle of different tube diameters, and frock versatility is good；Using screw mandrel spiral shell
Mother is used as moving component, and bar linkage motion mechanism, strength amplification coefficient is big, and manual physical's consumption is small；Using feed screw nut as fortune
Dynamic component, bar linkage motion mechanism, nut total kilometres are small, few between the bowlder of school.
