Description

The taper shank instrument that a kind of anti-cutter gets loose

Technical field

The present invention relates to machined field, the taper shank instrument that especially a kind of anti-cutter gets loose.

Background technology

Taper shank is a kind of conventional traditional handle of a knife instrument, as Morse taper shank, for installing taper-shank cutter.The location of handle of a knife and cutter, be connected and realize by Small Taper self-locking.In the middle of use, because handle of a knife and cutter are connected by Small Taper self-locking, there is error, handle of a knife and cutter and rotate and the reason such as tool sharpening is stressed in the tapering due to handle of a knife and cutter, cutter easily gets loose, cause forge a knife, damage lathe, workpiece scraps and the consequence of security incident, can not realize High-speed machining.

Summary of the invention

The object of the present invention is to provide on a kind of handle of a knife and have hole for subsequent use, by the screw in compression cutter that links closely, make cutter obtain axial force, thus reach relaxation effect, accelerate processing feed, efficient high-speed is processed, percent defective is low, the taper shank instrument that a kind of anti-cutter that safety coefficient is high gets loose.

Technical solution of the present invention is such, the taper shank instrument that a kind of anti-cutter gets loose, comprise handle of a knife, tightening screw, cutter, the large end angle of taper hole, axially eccentric, cutter screw, it is characterized in that cutter (3) is arranged on handle of a knife (1), interface between handle of a knife (1) with cutter (3) coordinates and is drilled with screw, tightening screw (2) enters the screw of handle of a knife (1) by the large end of taper hole of cutter (3), by tightening screw (2) handle of a knife (1), cutter (3) tightens up, the taper hole of cutter (3) is taper hole large end angle α, tightening screw (2) to be arranged on after the taper hole of cutter (3) wherein with cone limit axially eccentric e, cutter (3) has cutter screw φ, at handle of a knife (1) pinching screw and tightening screw (2), the opposite of pinching screw is installed and operates on tool screw φ, its position install with cutter (3) after taper hole position corresponding, cutter screw φ is as a secondary orifices of cutter (3), handle of a knife (1) has the screw becoming the taper hole of angle large end angle α with cutter (3) axis above.

Tightening screw (2) is cone end hex screw, is screwed on the screw of handle of a knife (1) by the taper hole of cutter (3).

The screw of handle of a knife (1) and the through hole of cutter (3) are axial eccentric e.

Cutter screw φ coordinates with drill jig and manufactures.

Taper hole on cutter (3) becomes taper hole large end angle α with the axial line of handle of a knife (1).

Compared with prior art, the invention has the beneficial effects as follows, key point of the present invention is and old taper shank ratio, it is by tightening screw or pinching screw, overcomes the shortcoming easily got loose when taper-shank cutter uses, ensure that installation accuracy and cutter rigidity, High-speed machining can be realized, raise the efficiency, avoid the accident of getting loose, and mounting or dismounting are convenient.Handle of a knife of the present invention has a hole for subsequent use, play its drill jig effect, utilize drilling machine, required taper hole is gone out to some cutter rapid processing without taper hole, thus realizes locking.

Fig. 3 is that the installation diagram of prior art adds partial sectional view.

Reference numeral: handle of a knife (1), tightening screw (2), cutter (3), taper hole large end angle α, axially eccentric e, cutter screw φ.

Detailed description of the invention

Below in conjunction with accompanying drawing, the invention will be further described

Embodiment 1, with reference to shown in accompanying drawing 1, handle of a knife (1) has cutter screw e, cutter (3) there is taper hole be taper hole large end angle α, handle of a knife (1) and cutter (3) have screw and taper hole in its assembled state screw and taper hole at axial eccentric e, its screw center is at interior (cone small end), cutter taper hole center is (cone is held greatly) outside, tightening screw (2) is a cone end hex screw, it is screwed on handle of a knife (1) screw, because screw becomes eccentric with taper hole, cutter (3) the screw conical surface and handle of a knife (1) are gone up, and taper hole is unidirectional to be contacted, cutter (3) is made to obtain the inner axial force of a handle of a knife (1), thus reach the locking effect of cutter.Cutter (3) is arranged on handle of a knife (1), interface between handle of a knife (1) with cutter (3) coordinates and is drilled with screw, tightening screw (2) is used to be arranged on screw afterwards, by tightening screw (2), handle of a knife (1), cutter (3) are tightened up, what wherein cutter (3) left is through hole, what handle of a knife (1) was opened is screw, but cutter (3) but hole screw, may also be unthreaded hole.The hole of cutter (3) is taper hole, and the hole of cutter (3) is taper hole.It is cutter screw φ that the subtend of handle of a knife (1) clamping screw has a hole, its position install with cutter (3) after taper hole position corresponding, purposes is provided with to some the cutter having taper hole, drill jig is made with it after being arranged on handle of a knife (1), process taper hole fast and accurately with common drilling, thus can locking functions be used when using these universal cutters.

Embodiment 2, accompanying drawing 2 is that anti-cutter of the present invention gets loose the another kind of taper shank.Handle of a knife (1), tightening screw (2), cutter (3).Handle of a knife (1) has the screw becoming α angle with axis above, and (3) have inclined surface with it with cutter, are tightened by tightening screw (2), makes cutter (3) obtain an axial thrust load all the time toward cone small end, thus reaches the locking effect of cutter.

Embodiment 3, (3) have inclined hole with cutter, and handle of a knife (1) corresponding inclined hole has taper hole, and it cooperatively interacts and manufactures, and inclined hole becomes taper hole large end angle α with handle of a knife axial line.By tightening screw (2) conical surface monolateral compression cutter (3) taper hole, make cutter (3) obtain an axial thrust load all the time, thus reach the effect loosened.Or handle of a knife (1) has above and becomes taper hole large end angle α with axis, (3) have inclined surface with it with cutter, tightened by tightening screw (2), cutter (3) is made on handle of a knife (1), to have opened individual screw all the time, (1) opens taper hole with cutter, mounting cutter (3) rear bolt hole and the certain distance of taper hole off-centring i.e. axial eccentric e, obtains an axial thrust load toward boring small end, thus reaches the locking effect of cutter.Handle of a knife (1) has a hole for subsequent use and cutter axis hole φ, play its drill jig effect, utilize drilling machine, required taper hole is gone out to some cutter rapid processing without taper hole.
