Description
Technical field
The utility model relates to a kind of machining tool, particularly relates to a kind of rotary valve hole machined reamer.
Background technology
Carburetor is under the vacuum action of engine operation generation, and by the mechanical device that a certain proportion of gasoline mixes with air, carburetor is as a kind of mechanical device of precision, and it can be referred to as " heart " of engine to the important function of engine.Carburetor inside is provided with rotary valve hole, this rotary valve hole is stepped hole, in prior art, need to process at twice during the rotary valve hole of processing carburetor, first process large diameter hole and on the basis of large diameter hole, reprocess small diameter bore again make the rotary valve hole of carburetor be stepped hole.Such processing mode is length consuming time not only, and skew easily appears in secondary operations causing hole position, reduces the accuracy of product.
Utility model content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model be to provide a kind of can the rotary valve hole machined reamer of disposable processing step hole.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of rotary valve hole machined reamer, comprise handle of a knife and cutter head, described cutter head comprises the first rank cutter head and second-order cutter head, this the first rank cutter head is fixedly connected with second-order cutter head, described first rank cutter head is connected with handle of a knife, and described first rank cutter head and second-order cutter head are equipped with at least two knife plates, and this knife plate is provided with blade, the length of described first rank cutter head is at least 40.0cm, and the length of described second-order cutter head is 3.3cm.
Further, described first rank cutter head is provided with two knife plates, and this knife plate is 180 degree of distributions, and the distance between described knife plate upper knife edge is 21.3cm, meets the requirement of rotary valve hole machined.
Further, described second-order cutter head is provided with two knife plates, and this knife plate is 180 degree of distributions, and the distance between described knife plate upper knife edge is 4.0cm, meets the requirement of rotary valve hole machined.
Further, described first rank cutter head and second-order cutter head form circulation passage between two adjacent knife plates, and this circulation passage is operationally for channel of chip removal also helps the circulation of cooling fluid.
Further, the anterior angle of described first rank cutter head and second-order cutter head is 0 degree, and anterior angle can affect cutting edge shape, and this rotary valve hole machined reamer anterior angle can prevent tooth shape from distorting in order to 0 degree, increases the service life of blade.
Further, the relief angle of described first rank cutter head and second-order cutter head is 5 degree, and the main function of relief angle is the friction after reducing between knife face and transitional surface, and the relief angle of blade is that 5 degree of unlikely changes of radial dimension of workpiece to be added after refacing made are too large.
Compared with prior art, the utility model has the advantage of: the utility model compact conformation, cutter head comprises the first rank cutter head and second-order cutter head, the length of the first rank cutter head all meets the requirement of the large diameter hole processing carburetor rotary valve hole with the distance of relative blade, length and the relative blade spacing of second-order cutter head all meet the requirement of the small diameter bore of processing carburetor rotary valve hole, drilling machine is coordinated to use this rotary valve hole machined reamer, disposablely can add carburetor rotary valve hole, it is made to reach the requirement of stepped hole, make hole site more accurately and reduce process time, this rotary valve hole machined reamer designing is practical, be applicable to large-scale promotion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cross section of the utility model first rank cutter head;
Fig. 3 is the cross section of the utility model second-order cutter head.
Detailed description of the invention
As Figure 1-3, a kind of rotary valve hole machined reamer, comprise handle of a knife 1 and cutter head, described cutter head comprises the first rank cutter head 2 and second-order cutter head 5, this the first rank cutter head 2 is fixedly connected with second-order cutter head 5, described first rank cutter head 2 is connected with handle of a knife 1, described first rank cutter head 2 is equipped with two knife plates 3 with second-order cutter head 5, circulation passage 6 is provided with between two adjacent knife plates 3, this knife plate 3 is provided with blade 4, distance on first rank cutter head 2 between two blades 4 is 21.3cm, the length of the first rank cutter head is for being 40.0cm, distance on second-order cutter head 5 between two blades 3 is 4.0cm, the length of second-order cutter head is 3.3cm, the anterior angle of the first rank cutter head and second-order cutter head is equal 0 degree, the relief angle of the first rank cutter head and second-order cutter head is 5 degree.
During tradition processing carburetor rotary valve hole, first process large diameter hole on the basis of large diameter hole, to reprocess small diameter bore again make the rotary valve hole of carburetor be stepped hole, workpiece is made to reach the requirement of stepped hole, but process length consuming time, production cost is high, and processing makes the accuracy of hole site reduce at twice, the utility model design coordinates machining to need, be applied on drilling machine and can reduce process time, increase work efficiency, in use, handle of a knife 1 connects drilling machine, second-order cutter head 5 first contact workpiece to be added and play when reamer machining part keep cutter head honest cut pin direction, first rank cutter head 2 carries out reaming more to machined part, carburetor rotary valve hole is finally made to reach stepped hole effect.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in previous embodiment, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment technical scheme of the utility model.
