Description
Technical field：
The utility model is related to a kind of progress of the welding bead surface of SAW spiral welded pipe to oil, natural gas line
The device of grinding.
Background technology：
Welding bead on the SAW spiral welded pipes outer wall such as transfer oil, natural gas has certain height, is making steel pipe
When outside surface anticorrosion, outer surface of steel tube is completely covered anti-corrosion material, wherein to the anti-corrosion layer thickness and steel of welding bead outer surface
The anti-corrosion layer thickness at other positions of tube outer surface, there is certain proportion requirement in the standard used.It is anti-to meet welding bead surface
The anti-corrosion layer thickness of rotten layer thickness, other positions will be thickened accordingly, is increased the dosage of anti-corrosion material, is increased the anti-corrosion of steel pipe
Cost.
If weld seam is ground away a part, the dosage of anti-corrosion material can be reduced, reduces production cost, but at present also
The equipment that automatic grinding can not be carried out in the production line to spiral welding bead.It, can only be by worker with manually if be ground
Tool completes grinding work, and recruitment is more, and labor intensity is big, and work efficiency is low.Currently, not yet manufacturer using such method into
Row production operation, so being badly in need of a kind of equipment of continuous grinding welding bead of development to solve problem above.
Invention content：
The technical problem to be solved by the utility model is to provide one kind can it is on-line automatic continuously to outer wall of steel pipe welding bead into
Row grinding, the full welding bead milling drum of spiral seam to reduce anti-corrosion material dosage.
What above-mentioned purpose was realized in：It includes pedestal, and pedestal is equipped with displacement mechanism, and the displacement mechanism includes
It is connected with bottom plate on the slideway being fixed on the base, with the linear slider of slideway cooperation installation, displacement motor is mounted on bottom plate,
Turntable is housed on displacement motor power output shaft, sets several displacement metering-orifices on turntable, each displacement metering-orifice and the turntable center of circle away from
From difference, there are hinge seat, the rear end of hinge axis to be mounted on the top of hinge seat, hinge by shaft on the pedestal at slideway rear
The front end of axis is connected with adjustment bolt, and adjustment bolt is connected with connecting plate, and the front end of connecting plate is equipped with bearing, bearing hole and turns
A displacement metering-orifice on disk is bolted, and thus connecting plate and turntable link together, displacement motor work
Drive turntable rotation, under the action of connecting plate, adjustment bolt, hinge axis, bottom plate is driven to move reciprocatingly on slideway；
There is holder on bottom plate, there is top plate, the cylinder body of lifting cylinder to be mounted on bottom plate by lower rotary shaft above bottom plate,
The cylinder rod of lifting cylinder is connected by one end of upper shaft and top plate, and the top of holder connects also by the other end of shaft and top plate
It connects, sun gear（It is ground active wheel）By axis on sun wheel support, sun gear frame bottom is fixed by bolts on top plate；
For abrasive belt wheel on the output shaft of motor, motor has screw on planker on planker, has lead screw, screw to be mounted in silk on bottom plate
On bar, the outer end of lead screw is connected with handle, and abrasive band is sleeved on sun gear and abrasive belt wheel.
The utility model has the advantages that：The present apparatus is mounted on SAW spiral welded pipe automatic assembly line, passes through displacement
Mechanism and lifting cylinder are adjusted operating position, and after steel pipe completes automatic welding, external welding bead surface carries out automatic continuous
Grinding makes subsequent preservative process reduce the use of anti-corrosion material, plays the role of cost efficiency.The present apparatus can it is online, automatic,
Continuous work.
