Abstract
The invention discloses a kind of integral type drilling and tapping cutter and its manufacturing methods, including bit part, screw tap part, withdrawing slot part and shank, the bit part is in the front end of integral type drilling and tapping cutter, screw tap part, which is in the middle part of integral type drilling and tapping cutter and links up with bit part, to connect, one section of escape is equipped between screw tap part and shank, the shank is in honest hexa-prism, and locating slot is equipped on the prism side of shank, and the locating slot is strip.In use process using steel ball positioning action in clamping device in locating slot, increase considerably chucking power of the integral type drilling and tapping cutter in fixture, the state of clamping is more stable, reduce the shaking of integral type drilling and tapping cutter work in-process, positioning accuracy and machining accuracy have obtained significant raising, improve the production efficiency of drilling and tapping.
Description
Technical field
The invention belongs to machining equipment technical fields, and in particular to a kind of integral type drilling and tapping cutter and its manufacture
Method.
Background technique
Drilling and tapping are a kind of processing methods relatively conventional in machining, common drill bit come drilled, reaming
Or the machining of spot-facing；And for the internal screw thread of small size, silk dimension is almost unique process tool.Usual drilling and
Tapping is one in front and one in back completed as two individual processes, is needed to remove on drill bit after completing drilling and is again loaded onto screw tap, and one
Aspect, in actual operation, since drill bit and screw tap clamp unstable in clamper, the axial and circumferential of drill bit and screw tap are equal
Small displacement can be generated, the shaking and bounce of drill bit and screw tap are easily caused, on the other hand since drill bit and screw tap are inherently deposited
In coaxiality error, the cutter dismounting for processing midway easily forms accumulated error, and not only manufacturing procedure is complicated, machining accuracy
Receive strong influence.
Summary of the invention
It is high that it is an object of the invention to a kind of precision, the simple integral type drilling and tapping cutter of process and its manufacturing method.
The technical scheme is that a kind of integral type drilling and tapping cutter, including bit part, screw tap part, escape
Part and shank, the bit part are in the front end of integral type drilling and tapping cutter, and screw tap part is in integral type drilling and attacks
The middle part of silk cutter and with bit part is coherent connects, one section of escape is equipped between screw tap part and shank, the shank is in
Honest hexa-prism, locating slot is equipped on the prism side of shank, and the locating slot is strip.
A kind of manufacturing method of the integral type drilling and tapping cutter of high manufacturing accuracy, including following preparation step：
(1) blanking：It is 90mm, the stainless-steel pipe that diameter is 14 that vehicle, which takes length,；
(2) it is segmented turning：(2-1) vehicle bit part：φ8 .8×20mm；
(2-2) thread wimble fraction：φ10 .3×25mm；(2-3) vehicle is by cutter groove：φ8 .4×17mm；(2-4) vehicle shank：φ12
.7×28mm；
(3) Milling Machining：(3-1) mills shank hex surface：Corresponding surface diameter；(3-2) mills locating slot：A positioning is processed in hex surface
Slot, length are 10 passwords, and width 5mm, hole depth is 2 .5mm；
(4) it is heat-treated：Overall vacuum quenching is carried out, the hardness for quenching acquisition is HRC62-65；
(5) peripheral milling：(5-1) crusher drill part：(5-2) grinds screw tap part：(5-3) grinds shank：
(6) helicla flute is ground：Helix angle is 30 °, and spiral groove bar number is 2；
(7) it grinds one's teeth in sleep：Mill specification is the screw tap of the .5mm of M10 × 1；
(8) screw tap front opening：Opening size is φ 8 .3 × 4 .5mm；
(9) bit part clear side：Cutting edge is ground, Tool in Cutting resistance is reduced；
(10) bit part is open：Opening angle is 135 ° ± 5 °；
(11) to bit part, screw tap part and allow cutter groove part carry out ti coat on diamond processing.
Beneficial effects of the present invention：
A kind of integral type drilling and tapping cutter of the invention and its manufacturing method, it is fixed using steel ball in clamping device in use process
Position acts in locating slot, increases considerably chucking power of the integral type drilling and tapping cutter in fixture, the state of clamping is more
Stablize, reduces the shaking of integral type drilling and tapping cutter work in-process, positioning accuracy and machining accuracy have obtained significantly mentioning
Height improves the production efficiency of drilling and tapping.
