Abstract
The utility model provides a cutting head with a quickly repaired external conical surface. The cutting head is provided with a positioning column, an inwardly recessed reamer and a drill rod, and is characterized in that the upper end of the center of the inwardly recessed reamer is fixedly connected with the center of the positioning column; the round surface of the inwardly recessed reamer is vertical to the axial line of the positioning column; the lower end of the center of the inwardly recessed reamer is fixedly connected with the center of the drill rod; the round surface of the inwardly recessed reamer is vertical to the axial line of the drill rod; the axial line of the positioning column is positioned on an axial extension line; and the angle between the cutting edge of the inwardly recessed reamer and the positioning column is 1/2 of the external conical angle. The cutting head can be mounted on an electric drill and the kinetic energy is provided by the electric drill. The cutting head has the benefits as follows: due to the adoption of the technical scheme, the external conical seal surface is more convenient and quick to repair; and the cutting head has the advantages of resource saving, simple structure, low repair cost, high production efficiency and the like.
Description
Technical field
The utility model belongs to a kind of ozzle fix tool of needs sealing, especially relates to a kind of male cone (strobilus masculinus) and repairs fast cutter head.
Background technology
Be used in existing technology airplane hydraulic pressure, then, the pipeline connecting pipe mouth of cold gas system is the outer cone shape mostly, because the ozzle of border extended is more and more thinner outwardly by conical base, so the situation of ozzle damage often occurs, then cause having produced sealing effectiveness decline.Because the parts precision on aircraft is very high, in prior art, can only lose former ozzle, more renew ozzle, cause producing the maintenance cost of great number, cause the technical problem of the wasting of resources.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of ozzle fix tool, especially is fit to a kind of male cone (strobilus masculinus) and repairs fast cutter head.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: provide a kind of male cone (strobilus masculinus) to repair fast cutter head, cutter head is provided with locating dowel, indent reamer, drilling rod; The upper end, the center of circle of indent reamer is fixedly connected with the center of circle of locating dowel, and the disc of indent reamer is mutually vertical with the axis of locating dowel; The lower end, the center of circle of indent reamer is fixedly connected with the center of circle of drilling rod, and the disc of indent reamer is mutually vertical with the axis of drilling rod; The axis of location group is positioned on the axis extended line of drilling rod, and the edge of a knife of indent reamer and the angle A of locating dowel are 1/2 of outer cone angle.Described male cone (strobilus masculinus) is repaired fast cutter head and can be arranged on electric drill by drilling rod, provides kinetic energy by electric drill.
Further, described indent reamer is straight knife or circular knife.
Further, be provided with chip-breaker between described indent reamer and drilling rod.
Described chip-breaker is double flute shape, with concentric second chip-breaker that arranges of article one chip-breaker.
Further, the lead angle of described indent reamer is 0 °-45 °.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, be that the maintenance of outer bevel sealing surface is convenient, quick; Have economize on resources, simple in structure, maintenance cost is low, the production efficiency advantages of higher.

The specific embodiment
As shown in Figure 1, the utility model provides a kind of male cone (strobilus masculinus) to repair fast cutter head, and cutter head is provided with locating dowel, indent reamer, drilling rod; The upper end, the center of circle of indent reamer is fixedly connected with the center of circle of locating dowel, and the disc of indent reamer is mutually vertical with the axis of locating dowel; The lower end, the center of circle of indent reamer is fixedly connected with the center of circle of drilling rod, and the disc of indent reamer is mutually vertical with the axis of drilling rod; The axis of location group is positioned on the axis extended line of drilling rod.Described indent reamer is straight knife.Be provided with chip-breaker between described indent reamer and drilling rod.Effect is: reduce friction, derive scrap.Due to the rotation of indent reamer, scrap is discharged from the bits groove, and obtains the good continuous outer poppet surface of precision.Simultaneously, the scrap that produces after indent reamer High Rotation Speed can not disperse and hurt sb.'s feelings, and lands but be introduced into storage bits gear buffering again.
As shown in Figure 2, the utility model provides another kind that described male cone (strobilus masculinus) is repaired cutter head fast to have the embodiment of two chip-breakers.Described indent reamer is circular knife.Described chip-breaker is double flute shape, with concentric second chip-breaker that arranges of article one chip-breaker.Effect is: in order to be fit to different machining conditions and the larger amount of feeding and the cutter life of singing as far as possible can be provided.The lead angle of described indent reamer is 0 °-45 °.
The course of work of this example: positioning body is pressed in pore, and the indent reamer is rotated processing take the center line of conduit as axis, and the position pin of injury on ozzle is cut away, and remakes an intact ozzle.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
