Abstract
The utility model relates to a milling cutter, which comprises a cutting head, a cutter handle and a positioning block, wherein the cutter handle is fixed on a chuck by clamping jaws; a strip groove is formed at the clamping position of the chuck on the cutter handle; the positioning block is positioned in the strip groove and extends out of the strip groove; when the cutter handle is fixed in the chuck, the extension end of the positioning block is pressed against one side of each of the clamping jaws. According to the milling cutter, the positions of the milling cutter and the clamping jaws are positioned by the positioning block, so that the phenomenon of slipping in the clamping jaws during the rotation of the cutter handle of the milling cutter is avoided effectively; and clamping force is not needed to be applied to the cutter handle of the milling cutter, so that the service life of the milling cutter is prolonged.
Description
Technical field
The utility model relates to a kind of cutter, and the milling cutter that especially a kind of machining is used belongs to machining and uses the cutting-tool engineering field.
Background technology
Milling cutter all is made up of cutter head and handle of a knife, and during the milling workpiece, normally the handle of a knife with milling cutter is fixed in the scroll chuck in machining, and machine tool chief axis drives milling cutter rotation milling workpiece.During milling, milling cutter is drawn out easily or in claw, skids under the effect of cutting component.In order to address this problem, when clamping milling handle, all can increase chucking power usually, operating personnel can twist when being fixed on milling cutter in the chuck always, twist always, up to tangible stubborn motionless, are fixed firmly by claw just feel the handle of a knife of milling cutter.But during milling, still need to observe constantly,, influence the crudy of workpiece between claw in order to avoid milling cutter skids.And, owing to when fixing milling cutter, too clamp milling cutter, also can cause the milling handle wearing and tearing, do not note also can interrupting handle of a knife the initiation security incident service life of not only having reduced milling cutter slightly.
Summary of the invention
The utility model purpose is for the deficiency that overcomes prior art a kind of milling cutter to be provided, and when it is fixed in the chuck, can between claw, not skid, and fixes to clamp conveniently long service life.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of milling cutter comprises cutter head, handle of a knife and locating piece; Said handle of a knife is fixed on the chuck through claw; On the said handle of a knife, be positioned at chuck clamping place and have bar-shaped trough; Said locating piece is positioned at bar-shaped trough, and locating piece extends bar-shaped trough; When said handle of a knife was fixed in the chuck, the locating piece elongated end propped up a side of claw.
Preferably, the elongated end of said locating piece is arranged in the triangular groove of claw; The face that said locating piece contacts with claw is the inclined-plane.
Preferably, said locating piece extends the length of bar-shaped trough, and is identical with the degree of depth of bar-shaped trough.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of milling cutter of the utility model scheme, in the bar-shaped trough of its handle of a knife, the locating piece that is provided with; Keep out the side at claw, milling cutter is when rotating, through the position location of locating piece with milling cutter and claw; When having prevented that effectively milling handle from rotating, the phenomenon of in claw, skidding takes place; Simultaneously, do not need again on milling handle, to apply clamping force, improved the service life of milling cutter, reduced processing cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of the milling cutter of the utility model when using;
Accompanying drawing 2 is the cutaway view at A place in the accompanying drawing 1;
Wherein: 1, cutter head; 2, handle of a knife; 3, claw; 4, triangular groove; 5, bar-shaped trough; 6, locating piece; 7, chuck.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Accompanying drawing 1,2 is the described a kind of milling cutter of the utility model, comprises cutter head 1, handle of a knife 2 and locating piece 6; Said handle of a knife 2 is fixed on the chuck 7 through claw 3; On the said handle of a knife 2, be positioned at chuck 7 clampings place and have bar-shaped trough 5; Said locating piece 6 is positioned at bar-shaped trough 5, and locating piece 6 extends bar-shaped trough 5; When said handle of a knife 2 was fixed in the chuck 7, locating piece 6 elongated ends propped up a side of claw 3; The elongated end of said locating piece 6 is arranged in the triangular groove 4 of claw 3; The face that said locating piece 6 contacts with claw 3 is the inclined-plane; Said locating piece 6 extends the length of bar-shaped trough 5, and is identical with the degree of depth of bar-shaped trough 5.
After above-mentioned milling cutter is fixed in the chuck 7,, prevented that handle of a knife 2 from skidding in claw 3, improved the precision of Milling Process and the crudy of workpiece, the service life of also having improved milling cutter because keeping out of locating piece 6 makes that claw 3 and handle of a knife 2 are spacing.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
