Abstract
The utility model discloses a reamer of an air inlet gun. The reamer comprises a cutter body and a cutter head, wherein water injection holes are arranged at the cutter body and the core of the cutter head; one side of the front end of the cutter head is provided with a cutting part; three water outlet holes that are communicated with the water injection holes are axially arranged on the cutter head at intervals; the first water outlet hole is in alignment with a cutter tip of the cutting part; the radial included angle between the axes of the second water outlet hole and the first water outlet hole is 40-50 DEG; and the radial included angle between the axes of the second water outlet hole and the third water outlet hole is 80-100 DEG. The three water outlet holes are dispersedly arranged, so as to improve the utilization ratio of the water outlet holes and prevent the cuttings from being accumulated on the surface of a workpiece, so that the cutting and processing quality and the processing efficiency are improved, and the quality of the workpiece is greatly improved as well.
Description
Technical field
The utility model belongs to the Machining Technology field, particularly a kind of boring cutter that is used for machining high-precision cylinder hole.
Background technology
Along with development of science and technology, machinery manufacturing industry also is more and more higher to the requirement of machining accuracy, and as air inlet rifle reamer, it can directly influence the machining accuracy of machine-building.The cutting tip of air inlet rifle reamer mainly is composite polycrystal-diamond (or polycrystalline cubic boron nitride composite sheet), this composite sheet is formed through the HTHP compacting by polycrystalline diamond layer (or polycrystalline cubic boron nitride layer) and hard alloy layer, and composite sheet is in the same place by solder bond with cutter hub.At present, air inlet rifle reamer is a single-point tool, is provided with four apopores in the cutter hub, and the apopore position is arranged in order from top to bottom, because the apopore distribution is too concentrated, causes impeded drainage easily, and smear metal is washed away not thorough, causes machining accuracy low low with working (machining) efficiency.
The utility model content
The purpose of this utility model provides a kind of machining accuracy height, air inlet rifle reamer that working (machining) efficiency is high.
For achieving the above object, the technical solution of the utility model is: a kind of air inlet rifle reamer, comprise cutter hub and cutter head, cutter hub and cutter head core are provided with water injection hole, cutter head front end one side is provided with cutting tip, and axially spaced-apart is provided with three apopores that communicate with water injection hole on the described cutter head, and first apopore is aimed at the point of a knife of cutting tip, between second apopore and the first apopore axis radially angle be 40 °～50 °, between second apopore and the 3rd apopore axis radially angle be 80 °～100 °.
Described cutter hub front end is an inverted cone shape, and its back taper is 0.01～0.015/40; The cutter head front end is an inverted cone shape, and its back taper is 0.005/40.
Described cutter hub end is provided with the shank platform, and the shank platform parallels with cutting tip.
Three apopores of the present utility model not only axially spaced-apart distribute, and the point of a knife of the first apopore aligning cutting tip, has radially angle between second apopore and the first apopore axis, has radially angle between second apopore and the 3rd apopore axis, three apopores distribute and disperse, and improve the apopore utilization ratio, prevent that smear metal from accumulating at surface of the work, thereby improve machining quality and working (machining) efficiency, the workpiece quality also greatly promotes.
The shank platform of cutter hub end parallels with cutting tip, is convenient to the clamping cutter.
The utility model is simple in structure, reasonable in design, can improve the machining accuracy of workpiece, increases the service life, and improves working (machining) efficiency, strengthens product competitiveness.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2 and air inlet rifle reamer shown in Figure 3, it comprises cutter hub 1 and cutter head 2, and cutter hub 1 is provided with water injection hole 3 with the core of cutter head 2, and the front end of water injection hole 3 seals shutoff by screw, and cutter head 2 front ends one side is provided with cutting tip 4.Cutter hub 1 and cutter head 2 front ends are inverted cone shape, and back taper is respectively 0.01～0.015/40 and 0.005/40.Cutting tip 4 mainly is composite polycrystal-diamond (or polycrystalline cubic boron nitride composite sheet), this composite sheet is formed through the HTHP compacting by polycrystalline diamond layer (or polycrystalline cubic boron nitride layer) and hard alloy layer, and composite sheet and cutter head 2 combine by welding manner.Axially spaced-apart is provided with three apopores that communicate with water injection hole 3 on cutter head 2, first apopore 5 is aimed at the point of a knife of cutting tip 4, between second apopore 6 and first apopore, 5 axis radially angle be 40 °～50 °, between the 3rd apopore 7 and second apopore, 6 axis radially angle be 80 °～100 °, to reach the purpose that three apopores are fully disperseed, improve its utilization ratio, prevent that smear metal from accumulating at surface of the work, thereby improve machining quality and working (machining) efficiency.For the ease of the clamping cutter, cutter hub 1 end is provided with shank platform 8, and shank platform 8 parallels with cutting tip 4.
In the present embodiment, between second apopore 6 and first apopore, 5 axis radially angle be 45 °, between the 3rd apopore 7 and second apopore, 6 axis radially angle be 90 °.
