Abstract
The utility model provides a reverse-direction double-edge smoothing cutter which comprises a taper shank and a cutter holder. The utility model is characterized in that: internal threads are provided in a middle hole at one end of the taper shank; the internal threads and one end screw of the cutter holder are matched through a gasket and a locknut for cooperation; one end of the cutter holder is provided with a blind hole; the hole is internally provided with a spring and a bayonet pin; the bayonet pin is integrated with a sliding sleeve through a pin and can move in a middle long groove range of the cutter holder; a double-surface countersink cutter is slidably provided in a front through hole of the cutter holder; and the middle part of the double-surface countersink cutter is provided with a mortise which is engaged with a flat tenon at the top end of the bayonet pin. The reverse-direction double-edge smoothing cutter has the following advantages: simple structure, no requirement of performing turnover to a workpeice for cutting a lower surface, more convenient countersink cutter replacement, simple process, high production efficiency, etc.
Description
Technical field
The utility model relates to a kind of reverse twolip and wipes cutter off, is particularly useful for the cutter that the workpiece through-hole bottom face is wipeed off.
Background technology
In drilling operating, often run into and when the auger shell bolt throughhole, need wipe up and down both ends of the surface off, if use common countersink, but the strickling of upper surface forward, the strickling of lower surface then will be stood up workpiece just and can be carried out, and does the technology complexity like this, production efficiency is low, labour intensity is big.
Summary of the invention
The purpose of this utility model just provides a kind of reverse twolip and wipes cutter off, and it can make workpiece under the situation of not standing up the lower surface be wipeed off.
The purpose of this utility model is achieved in that this cutter comprises taper shank, knife bar, it is characterized in that described taper shank mesopore is provided with internal thread, internal thread and knife bar one terminal screw are used by pad and locking nut, the other end of described knife bar is provided with blind hole, spring and bayonet lock are housed in the hole, bayonet lock and sliding sleeve combine as a whole, can move in the elongated slot scope of the middle part of knife bar by bearing pin, two-sided countersink cunning is assigned in the knife bar front end through hole, and two-sided countersink middle part has a tongue-and-groove that matches with the flat tenon in bayonet lock top.
The utlity model has simple in structurely, workpiece need not stand up just can the scraping lower surface, and countersink is changed convenient, and technology is simple, characteristics such as production efficiency height.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
The contrast accompanying drawing as can be known, the utility model comprises taper shank 1, knife bar 2, it is characterized in that described taper shank 1 mesopore is provided with internal thread 3, internal thread 3 is used by pad 4 and locking nut 5 with knife bar 2 one terminal screw 2-1, described knife bar 2 one ends are provided with blind hole 6, spring 7 and bayonet lock 8 are housed in the hole, bayonet lock 8 combines as a whole, can move in elongated slot 11 scopes of the middle part of knife bar 2 by bearing pin 10 with sliding sleeve 9, two-sided countersink 12 sliding being assigned in the knife bar 2 front end through holes 13, two-sided countersink 12 middle parts have a tongue-and-groove 14 that matches with the flat tenon in bayonet lock 8 tops.
During work, taper shank 1 is packed in the drill press spindle hole, knife bar 2 passes the through hole 16 of workpiece 15 from top to bottom, sliding sleeve 9 drive bayonet locks 8 with hand push moves up, insert two-sided countersink 12 in the knife bar 2 front end through holes 13 this moment, unclamp sliding sleeve 9 then, thrust by spring 7, the flat tenon in bayonet lock 8 tops just snaps in the tongue-and-groove 14 of two-sided countersink 12, fall drill press spindle this moment, knife bar 2 upper end screw 2-1 are screwed in the internal thread 3 of taper shank 1, and fastening with locking nut 5, can carry out reverse scraping work to workpiece 15.
