Description
Technical field
Aperture apparatus in a kind of large-diameter steel pipe boring of the utility model, belong to boring endoporus equipment technical field.
Background technology
Large-diameter steel pipe is widely used in fired power generating unit, petrochemical equipment etc. now, and along with the development of domestic economy, the demand of large aperture steel pipe constantly increases.At present, domestic large-diameter steel pipe mainly adopts the method for centrifugal casting to make, because outer surface of steel tube and inner surface after casting are more coarse, steel pipe casting manufacturer often needs need to carry out roughing to steel pipe internal-surface and outer surface according to customer requirement, but existing boring machine can't meet above-mentioned requirements.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved has been to provide a kind of for the roughing large-diameter steel pipe, the interior aperture apparatus of the large-diameter steel pipe boring that working (machining) efficiency is high.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: aperture apparatus in a kind of large-diameter steel pipe boring, comprise: the boring machine main frame, be provided with pipe holder on the axis direction of described boring machine main frame, one end of boring bar is fixed on the chuck of boring machine main frame, the other end of described boring bar is movably arranged on pipe holder, and end is fixed with gear ring, on the inner length direction of described boring bar, leading screw is installed, and the surface of boring bar has slotted hole, described slotted hole is corresponding with leading screw, described leading screw and boring bar eccentric setting, and an end of leading screw is equipped with gear, described gear is positioned at the outside of pipe holder, and be meshed with gear ring, the cutter sleeve pipe box is contained on boring bar, and the cutter sleeve pipe is connected with leading screw by screw, screw on described cutter sleeve pipe is positioned at slotted hole, on described cutter sleeve pipe, cutter is installed.
Described cutter sleeve pipe and boring bar are matched in clearance.
The beneficial effect that the utility model compared with prior art had is: the utility model meshes by gear-wheel gear-ring, the reciprocal machined steel inside pipe wall of band cutter, and working (machining) efficiency is high, simple and convenient.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
The right view that Fig. 2 is Fig. 1.
In figure: 1 is the boring machine main frame, and 2 is pipe holder, and 3 is boring bar, and 4 is gear ring, and 5 is leading screw, and 6 is slotted hole, and 7 is gear, and 8 is the cutter sleeve pipe, and 9 is cutter, and 10 is large-diameter steel pipe.
The specific embodiment
As Fig. 1, shown in Fig. 2, aperture apparatus in a kind of large-diameter steel pipe boring, comprise: boring machine main frame 1, be provided with pipe holder 2 on the axis direction of described boring machine main frame 1, one end of boring bar 3 is fixed on the chuck of boring machine main frame 1, the other end of described boring bar 3 is movably arranged on pipe holder 2, and end is fixed with gear ring 4, on the inner length direction of described boring bar 3, leading screw 5 is installed, and the surface of boring bar 3 has slotted hole 6, described slotted hole 6 is corresponding with leading screw 5, described leading screw 5 and boring bar 3 eccentric settings, and an end of leading screw 5 is equipped with gear 7, described gear 7 is positioned at the outside of pipe holder 2, and be meshed with gear ring 4, cutter sleeve pipe 8 is sleeved on boring bar 3, and cutter sleeve pipe 8 is connected with leading screw 5 by screw, screw on described cutter sleeve pipe 8 is positioned at slotted hole 6, on described cutter sleeve pipe 8, cutter 9 is installed.
Described cutter sleeve pipe 8 is matched in clearance with boring bar 3.
Boring machine main frame and pipe holder in the utility model are all same as the prior art.
When the utility model is specifically used, large-diameter steel pipe 10 erection bracket are fixed between boring machine main frame 1 and pipe holder 2, and guarantee that large-diameter steel pipe 10 and boring bar 3 coaxially arrange, wherein, boring bar 3 is by boring machine main frame 1 driven rotary, to guarantee that cutter 9 can be around the steel duct smear metal, gear ring 4 meshes with gear 7 simultaneously, cutter 9 is connected with leading screw 5 by screw, when cutter 9 can be moved in a circle around boring bar 3 centers, then do rectilinear motion along leading screw 5, thereby can process large-diameter steel pipe, working (machining) efficiency is high, simple to operation.
The above is explained in detail embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-described embodiment, in the ken possessed those of ordinary skills, can also under the prerequisite that does not break away from the utility model aim, make various variations.
