Define.
Fig. 1 and Fig. 2 are please referred to, the utility model embodiment includes:
Embodiment 1
The utility model discloses a kind of replaceable compound knife system, comprising: composite knife bar 1, boring bar tool 2 and blade
3。
Wherein, the composite knife bar 1 includes cylindrical structure 11 and the conical structure for being connected to described 11 one end of cylindrical structure
12；The middle part of the cylindrical structure 11 and conical structure 12 has a through hole, and the shank of the boring bar tool 2 is from the circular cone knot
The through hole is inserted into 12 side of structure and the composite knife bar 1 is fixed；The composite knife bar 1 is located at the cylindrical structure 11 and circle
The two sides of 12 junction of wimble structure symmetrically open up fluted 13, and the blade 3 is fitted in the side of the conical structure 12 with side
The direction in face is vertical to be fixed in the groove 13.
Specifically, the shank of the boring bar tool 2 is milled with plane 21, and the side of the cylindrical structure 11 has screw hole
14, it is fixed by penetrating through the screw 4 of the screw hole 14 between the boring bar tool 2 and the composite knife bar 1.
The direction of the groove 13 towards 12 side of conical structure is equipped with screw hole, and the blade passes through described in perforation
The screw 5 of blade and screw hole is detachable to be fixed in the groove 13.The blade 3 has intact blade part
Complete chamfering work.
And a large amount of waste and old blade can be generated in turnery processing, machining generally only will cause these waste and old blades
Corner wear, and to blade side edge almost without damage, therefore, the waste and old blade that the utility model generates these turnery processings
It reuses, carries out chamfer cutting using the side edge of blade, by largely it was verified that the processing effect of these waste and old blades
With service life considerably beyond chamfer drill.By the use of these waste and old blades, a large amount of brill of falling knife on the one hand can be saved,
The cost of compound knife system is effectively reduced, the service life is longer for another aspect blade, can reduce the frequency of replacement.
The replaceable compound knife system of the utility model, the later period only needs to change blade, and the replacement and installation of blade are non-
It is often convenient, without that again to knife, only the blade of replacement need to be screwed in groove, accelerate production efficiency, also
Cost is saved.
The boring bar tool 2 is milling cutter or drill bit.With specific reference to required preparation hole the case where select.When needing to prepare
The hole of small aperture or when drilling in general plane, selection installation fried dough twist drill bit, cooperation blade carry out chamfering；Work as needs
When drilling on inclined-plane, irregular face or pre- hole carry out reaming, selection installation milling cutter hole milling.
Embodiment 2
The difference from embodiment 1 is that the composite knife bar 1 further includes upright bar 15, the upright bar 15 is fixed on the circle
The other end of rod structure 11.The middle part of the upright bar 15 has the threaded hole 16 being connected to the through hole, the threaded hole 16
Inside it is fitted with screw 4.By fitting depth of the regulation screw 4 in the threaded hole 16 of upright bar 15, to regulate and control milling cutter or fiber crops
The working depth that flower bores, to increase the use scope of replaceable compound knife system.
A kind of replaceable compound knife system of the utility model, improves production effect to machine the drilling chamfering in field
Rate, save the cost.The utility model carries out reaming cutting, hole milling by contrast test, using the milling cutter of size identical as aperture
Cutting has higher dimensional accuracy, avoids hole wall tilt phenomenon, and cooperation chamfering blade completes functions of reaming, chamfering once.Pass through
The re-using for the useless blade that can be generated in turnery processing, on the one hand reduces installation cost, and realizes waste secondary use, separately
On the one hand it improves assembly efficiency and use is the service life, help to improve the working efficiency of drilling.
