Description
Technical field
This utility model belongs to machine tool technical field, particularly relates to one and can process a kind of band cone on deep hole drilling machine
Degree and the boring cutter body for deep hole machining stepped hole tapering arc transition of arc transition endoporus.
Background technology
When the endoporus shown in manuscript 1, stepped hole transition portion is utilized on lathe loading onto shaping with lengthened tool arbor
Blade boring processing.Owing to knife bar extension elongation about 1000mm and shaping blade are wider, knife bar vibrates, and easily forges a knife, processing
Surface roughness, it is impossible to meet user's requirement, and production efficiency is the lowest.In consideration of it, we devise a kind of for depth drill
A kind of band tapering and the instrument of arc transition endoporus is processed on bed.
Summary of the invention
The purpose of this utility model is the processing band cone providing a kind of simple in construction, low cost of manufacture, work efficiency high
Degree and the boring cutter body for deep hole machining stepped hole tapering arc transition of arc transition endoporus.
The technical solution of the utility model is as follows: a kind of boring cutter body for deep hole machining stepped hole tapering arc transition,
This boring cutter body includes forming-tool block, cutter hub and wood key, and on the external cylindrical surface of described cutter hub, uniform four keyways, set in described keyway
Put wood key；The frustum position of described cutter hub is provided with a platform, and described platform offers two screwed holes, two screwed hole centers
Line is 30 degree of angles with the centrage of cutter hub, and described forming-tool block is fixed by screws on described cutter hub.
The carbide tool-block that four pieces of hard alloys are spliced, described hard alloy it is welded with on described forming-tool block
Cutter block is consistent with the circular arc at inner hole of workpiece step transition position to be processed, and the length of described carbide tool-block is more than inner hole of workpiece
The tapering length of transition position.
The good effect that the technical solution of the utility model produces is as follows: be machined with two on forming-tool block of the present utility model
Individual groove, unclamps screw, and forming-tool block moves along the platform milled out on cutter hub, can adjust the position of blade, such that it is able to add
The various sizes of endoporus of work, endoporus range of work φ B ± 10mm；Shape boring cutter body to be connected with drilling rod by rectangular thread, just
Property good, process endoporus at deep hole drilling machine, dimensional accuracy is easy to control, and surface quality is good, and production efficiency is high.

Detailed description of the invention
A kind of boring cutter body for deep hole machining tapering arc transition endoporus, as shown in Fig. 2,3,4,5,6,7, according to workpiece
Tapering at the diameter of endoporus and endoporus step transition, designed arc-shaped appearance shape boring cutter body, this shaping boring cutter body include forming-tool block,
Screw, cutter hub and wood key.On the external cylindrical surface of cutter hub, four keyways of the most uniform processing, at the built-in overwood of keyway
Key；Mill out a platform at the frustum position of cutter hub, platform bores the screwed hole of two M8, the two screwed hole line of centres and cuttves
The centrage of body becomes 30 °；Being spliced by four pieces of hard alloys according to tapering length by carbide tool-block 5(, be spliced into is hard
Matter alloy knife block length is more than the tapering length of inner hole of workpiece transition position) it is welded on forming-tool block, and carbide tool-block is ground
Become consistent with the circular arc at inner hole of workpiece step transition position to be processed；By packaged for forming-tool on cutter hub and tight with two screws
Gu.
During use, first inner hole of workpiece initial processing being shaped such as Fig. 5 on deep hole drilling machine, step transition position is stayed certain remaining
Amount, cutter hub is coupled with drilling rod by the saw screw thread at rear portion, cuts good for cutter block position adjustment by trial cut, it is ensured that bore size and
Inner hole of workpiece big hole dimension φ B is consistent, 30 ° of tapered portion and transition arc R25.4 boring is become.
Claims (2)
1. the boring cutter body for deep hole machining stepped hole tapering arc transition, it is characterised in that: this boring cutter body includes shaping
