Description
Technical field
The utility model relates to machine tool technical field, particularly relates to a kind of composite drill bit for processing bell housing counter sink.
Background technology
Bell housing inner chamber place has 13 processing requests to be Φ 13
+ 0.27 0hole, the end face in hole needs ream to put down, and there is 1 × 45 ° of chamfering in aperture.Conventional machining process is: use a kind of subland drill, as shown in Figure 1, comprise Morse taper shank 1 and drill body, drill body is formed by first spiral bit 2 grinding of Φ 34, front end is ground to second spiral bit 3 of Φ 13, Φ 34, Φ 13 junction are ground to countersink with ream planar end surface, carry out chamfering process again after processing.In process, this subland drill easily causes stress to concentrate in Φ 34, Φ 13 junction, frangibility, service life is short, and cause whole subland drill to be scrapped, use cost is high, and roughness is defective after flattening end surface, whole technical process operation is many, and man-hour is long, causes the manufacturing cost of bell housing higher.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of composite drill bit, instead of traditional countersunk head drill bit, extends the service life of drill bit, reduce the use cost of drill bit, shorten manufacturing procedure simultaneously, reduce the manufacturing cost of bell housing.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of composite drill bit, comprise Morse taper shank and drill body, described drill body comprises the first spiral bit and the second spiral bit that are detachably installed together, described first spiral bit and described Morse taper shank are set to one, described second spiral bit is positioned at described first spiral bit one end away from described Morse taper shank, the diameter of described first spiral bit is greater than the diameter of described second spiral bit, described first spiral bit is provided with the flat blade of ream and chamfering blade away from the end of one end of described Morse taper shank respectively by securing member.
Improve as one, a blind hole concentric with described first spiral bit is established in the end of described first spiral bit, described second spiral bit comprises drilling rod and drill bit, described drilling rod and described blind hole suitable, be provided with retention mechanism between described drilling rod and described second spiral bit.
As further improvement, described retention mechanism comprises the anti-rotation plane be arranged on described drilling rod, described anti-rotation plane is consistent with the bearing of trend of described drilling rod, and described second spiral bit has been threaded holding screw, and the end of described holding screw relies in described anti-rotation plane.
After have employed technique scheme, the beneficial effects of the utility model are: owing to devising the first spiral bit and the second spiral bit that are detachably installed together, when making, the first spiral bit and the second spiral bit can use different materials, to prevent the fracture of the second spiral bit, the second spiral bit can be dismantled when the second spiral bit damages to change simultaneously, whole drill bit need not be scrapped, reduce use cost; Again owing to devising the flat blade of ream and chamfering blade, can continue to implement the gentle chamfering process of ream after boring completes, simplify bell housing bore process flow process, reduce further the production cost of bell housing.
Because the flat blade of ream and chamfering blade use securing member to be arranged on the first spiral bit, not only ream can reach smooth bright and clean processing effect after putting down, and is convenient to dismounting and replacing, thus reduces the use cost of this composite drill bit.

In figure: 1, Morse taper shank, the 2, first spiral bit, the 3, second spiral bit, 4, Morse taper shank, the 5, first spiral bit, 51, blind hole, the 6, second spiral bit, 61, drilling rod, 62, drill bit, 63, anti-rotation plane, 7, the flat blade of ream, 8, chamfering blade.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 2, a kind of composite drill bit, comprise Morse taper shank 4 and drill body, drill body comprises the first spiral bit 5 and the second spiral bit 6 be detachably installed together, first spiral bit 5 is set to one with Morse taper shank 4, second spiral bit 6 is positioned at the first spiral bit 5 one end away from Morse taper shank 4, the diameter of the first spiral bit 5 is greater than the diameter of the second spiral bit 6, first spiral bit 5 is provided with the flat blade 7 of ream and chamfering blade 8 away from the end of one end of Morse taper shank 4 respectively by securing member, the flat blade 7 of ream is provided with two and scope between the external diameter and the external diameter of the second spiral bit 6 of the first spiral bit 5, chamfering blade 8 is then arranged on the first spiral bit 5 of the second spiral bit 6 outer radial position, the blade of chamfering blade 8 is corresponding with the aperture that the second spiral bit 6 is holed, the angle of chamfering blade 8 can adjust as required, the flat blade 7 of ream and chamfering blade 8 use screw fastening usually, be convenient to dismounting or replacing.
Illustrate the detachable mounting means between the first spiral bit 5 and the second spiral bit 6 below, a blind hole 51 concentric with the first spiral bit 5 is established in the end of the first spiral bit 5, second spiral bit 6 comprises drilling rod 61 and drill bit 62, wherein, drilling rod 61 and drill bit 62 are coaxially arranged and the diameter of drilling rod 61 is less than the diameter of drill bit 62, drilling rod 61 is suitable with blind hole 51, retention mechanism is provided with between drilling rod 61 and the second spiral bit 6, retention mechanism comprises the anti-rotation plane 63 be arranged on drilling rod 61, anti-rotation plane 63 is consistent with the bearing of trend of drilling rod 61, second spiral bit 6 has been threaded holding screw (not shown), the end of holding screw relies in anti-rotation plane 63.
During making, first spiral bit 5 and the second spiral bit 6 can use different materials, second spiral bit 6 uses high strength steel, and the first spiral bit 5 can use medium carbon steel material, the manufacturing cost of composite drill bit can either be reduced, effectively can reduce again the fracture of the second spiral bit 6, improve the service life of the second spiral bit 6.During use, when there being damage in the second spiral bit 6, the flat blade 7 of ream or chamfering blade 8, can dismounting and change at any time, be unlikely to whole composite drill bit and scrap, reduce further the use cost of composite drill bit.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, done all conversion, all drop within protection domain of the present utility model.
