Abstract
A kind of auger bit drilling deep holes positioning device that lengthens is the improvement being related on center lathe with the Simple positioning device structures of auger bit drilling deep holes.The present invention provides a kind of Simple positioning device of lathe auger bit drilling deep holes that the aperture for ensuring deep hole processing is not overproof.The present invention includes drill bushing, and the two sides of structural feature drill bushing are respectively arranged with workpiece hole, drill bit bore, is the connector sleeve with notch between workpiece hole, drill bit bore, is provided with holding screw on the drill bushing of workpiece hole.
Description
Technical field
The present invention is related on center lathe with the improvement of the Simple positioning device structure of auger bit drilling deep holes.
Background technique
In mechanical processing process, the hole drilled out the case where using auger bit drilling deep holes on center lathe is frequently encountered
It is overproof often to there is aperture.This is because needing repeatedly to exit drill bit in boring procedure, chip is exported, drill bit is oriented in addition
Caused by land and aperture friction.
If the required precision in hole is not high, such case occur can also receive, but higher for the required precision in hole,
Or require when aperture processes screw thread, orifice diameter is overproof, is unacceptable.
Summary of the invention
The present invention addresses the above problem, provides a kind of lathe auger bit that the aperture for ensuring deep hole processing is not overproof
The Simple positioning device of drilling deep hole.
Above-mentioned purpose to realize the present invention, the present invention adopt the following technical scheme that the present invention includes drill bushing, and structure is wanted
The two sides of point drill bushing are respectively arranged with workpiece hole, drill bit bore, are the connector sleeve with notch, workpiece between workpiece hole, drill bit bore
Holding screw is provided on the drill bushing in hole.
Beneficial effects of the present invention:
The workpiece hole of drill bushing of the invention is connected with excircle of workpiece；Drill bit bore is oriented to as drill bit and location hole, instead of workpiece
Friction is born in aperture, can prevent the diameter dimension in aperture from constantly becoming larger；It is provided with notch on the connector sleeve of drill bushing of the invention, is used for
Fill cutting fluid and chip removal, in the case where guaranteeing necessary strength conditions, notch is opened more larger as far as possible, can be improved cutting fluid injection with
Chip removal effect.Above two structures can ensure that the aperture of drilling deep hole is not overproof, and qualification rate meets the needs of production up to 100%.
Detailed description of the invention:
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment:
The present invention includes drill bushing 1, and the two sides of drill bushing 1 are respectively arranged with workpiece hole 5, drill bit bore 2, between workpiece hole 5, drill bit bore 2
For the connector sleeve 3 with notch 4, holding screw 6 is provided on the drill bushing 1 of workpiece hole 5.
To keep workpiece 8 preferably fixed, 4 holding screws 6 can be set on the drill bushing 1 of workpiece hole 5.
Settable 4 longitudinal notches 4 on connector sleeve 3, so as to better chip removal or injection cutting fluid.
Illustrate first use process of the invention with reference to the accompanying drawing:
Firstly, the workpiece hole 5 of drill bushing 1 is connected with the workpiece 8 on chuck 9, it is then with holding screw 6 that workpiece 8 is fixed；Again will
Drill bit 7 passes through drill bit bore 2.In boring procedure, at the notch 4 of connector sleeve 3, cutting fluid and chip removal are injected at any time.
