Abstract
The invention provides a slotting tool for an orthogonal hole. The slotting tool comprises a drill handle body, wherein a back pad and a knife sheath are arranged in a bearing hole in the front end of the drill handle body; a bearing is arranged between the back pad and the knife sheath; one end of the bearing is fixed by a check ring; the other end of the bearing is fixedly mounted on the knife sheath by a front pad; a bearing end cover is mounted at the outer end of the bearing; the bearing end cover is fixedly mounted on the drill handle body through an inner hexagon screw; an adjusting screw is arranged in an internal thread hole in the rear end of the knife sheath; a tool is mounted in an unthreaded hole in the front end of the knife sheath; the tool is fixed in the knife sheath through a locking screw. The slotting tool disclosed by the invention has the advantages of simple structure, convenient operation and high efficiency.
Description
Technical field
The invention belongs to mechanical field, relate in particular to a kind of positive hexagonal hole slotting drilling tool.
Background technology
A little end face centers band hexagonal hole axial workpiece often can be run in the middle of production and processing; the mode of processing these part hexagonal holes is: be washed into by hand; namely workpiece bottom outlet is bored; then with the chuck kept flat Workpiece clamping; hand-held shaping six side's punching pin alignment pieces bottom outlets again; another hand-held hammer repeatedly beats punching pin top, is washed into by hexagonal hole.The hexagonal hole low precision processed like this, presentation quality is poor, and punching pin easily produces tipping damage, and rushing the also difficult taking-up of rear punching pin, efficiency is too low, and labour intensity is larger.
Summary of the invention
The invention provides a kind of positive hexagonal hole slotting drilling tool, solve the shortcoming that in background technology, manual working (machining) efficiency is low, of poor quality, labour intensity is large.
Technical scheme of the present invention is achieved in that positive hexagonal hole slotting drilling tool, comprise drillstock body, rear pad and broach shell is provided with in the dead eye of drillstock body front end, bearing is provided with between rear pad and broach shell, bearing one end back-up ring is fixed, the other end is fixedly mounted on broach shell by foremast, bearing outer end is equipped with bearing (ball) cover, bearing (ball) cover is fixedly satisfied with on drillstock body by soket head cap screw, internal thread hole, broach shell rear end is provided with adjustment screw, be equipped with cutter in the unthreaded hole of front end, cutter is fixed in broach shell by lock-screw;
Between the center line of cutter and the center line of drillstock body, angle α equals the angle theta between cutter front end face and vertical plane;
The center line of cutter and the center line of drillstock body intersect at cutter front end face central point C.
The invention has the beneficial effects as follows: the front end face of cutter of the present invention and workpiece end face have certain angle, will rotate together with bearing inner ring with broach shell and other part be arranged on broach shell by carry its tools when workpiece rotates, all the time be that a blade of cutter is cutting, cutting resistance is little, be easy to go out positive hexagonal hole, withdrawing is simple, and continuous cutting is once washed into, the hexagonal hole quality gone out is high, and structure is simple, easy to operate, efficiency is high.
Accompanying drawing explanation
Fig. 1 is generalized section of the present invention.
Part illustrates: 1, drillstock body, 2, rear pad, 3, back-up ring, 4, bearing, 5, soket head cap screw, 6, foremast, 7, lock-screw, 8, cutter, 9, broach shell, 10, bearing (ball) cover, 11, adjustment screw, and C, central point.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described: positive hexagonal hole slotting drilling tool, comprise drillstock body 1, rear pad 2 and broach shell 9 is provided with in the dead eye of drillstock body 1 front end, bearing 4 is provided with between rear pad 2 and broach shell 9, bearing 4 one end back-up ring 3 is fixed, the other end is fixedly mounted on broach shell 9 by foremast 6, bearing 4 outer end is equipped with bearing (ball) cover 10, bearing (ball) cover 10 is fixedly satisfied with on drillstock body 1 by soket head cap screw 5, internal thread hole, broach shell 9 rear end is provided with adjustment screw 11, cutter 8 is equipped with in the unthreaded hole of front end, cutter 8 is fixed in broach shell 9 by lock-screw 7, between the center line of cutter 8 and the center line of drillstock body 1, angle α equals the angle theta between cutter 8 front end face and vertical plane, the center line of cutter 8 and the center line of drillstock body 1 intersect at cutter 8 front end face central point C.
The positive hexagonal hole slotting drilling tool adjusted is put into Mohs No. 4 taper holes of tail stock, clamp on the chuck of the trade union college to lathe that have bored bottom outlet, by tailstock near end face, locking tailstock, start lathe, the front end face of cutter 8 and workpiece end face have certain angle theta, namely the angle theta between cutter 8 front end face and vertical plane, will rotate together with bearing inner ring with broach shell 9 and other part be arranged on broach shell 9 by carry its tools 8 when workpiece rotates, all the time be that a blade of cutter 8 is cutting, cutting resistance is little, now manually shake tailstock axial feed, be easy to go out positive hexagonal hole, owing to being hand-operated tailstock, so withdrawing is easy to, and continuous cutting is once washed into, the hexagonal hole quality gone out is high, this apparatus structure is simple, easy to operate, efficiency is high.
