Description

A kind of collet-type numerical control knife handle of non-threaded gap and torsion deformation

Technical field

The utility model relates to the collet-type numbers that numerical control field of tool more particularly to a kind of non-threaded gap and torsion deform Control knife handle.

Background technique

Collet-type numerical control knife handle kind tool system is classified as two classes at present: one kind is to pass through the devices such as built-in screw to connect collet chuck Cooperate with ontology knife handle, collet chuck deformation retract clamp-on tool is made by tightening force, but such clamping mode clamping force is small, and There is the unstable deformation of collet chuck caused by rotary torsion；Another kind is pressure cap formula, is cooperated collet chuck by the connection of screw thread in ontology Contract deformation, but such form by be threadedly engaged difficulty reach high-precision, also have rotary torsion cause to deform it is unstable existing As.

Utility model content

The collet chuck of a kind of in order to overcome the deficiencies of the prior art, the utility model provides non-threaded gap and torsion deformation Formula numerical control knife handle has the effect of to guarantee that cutter is steady, high-speed cutting, reduces cutter use cost.

The utility model adopts the following technical solutions:

The collet-type numerical control knife handle of a kind of non-threaded gap and torsion deformation, including knife handle ontology and nut housing, nut Jacket internal and the mutually matched straight platform of positioning of knife handle body exterior setting；Cylinder inside the nut housing and knife handle inner body Between be equipped with ostium circle, and the outer circumferential of ostium circle have retaining ring.

Further, the contact surface of the nut housing and ostium circle is respectively provided with taper.

Further, the ostium circle is handled using partial end-face titanizing.

Further, the retaining ring is made of steel wire.

Further, the groove matched with ostium circle is equipped on the outside of the cylinder.

Compared with prior art, the utility model has the beneficial effects that

(1) locking torsion is eliminated in the split type rotation of the nut of the utility model, solves elastic collet chuck in contraction distortion, By each matable assembly mutually move generation unstable factor and caused by precision, strength problem；

(2) the utility model is linked together nut housing and ostium circle by built-in retaining ring, prevents from falling off, Ostium circle is handled using partial end-face titanizing, increases wearability, eliminates damage of the collet chuck exchange to nut；

(3) the collet chuck knife handle of the utility model can guarantee that cutter is steady, high-speed cutting during the cutting process, reduce knife Has use cost, and high-speed smooth cutting greatly improves production efficiency and product quality.

Specific embodiment

It is noted that following detailed description is all illustrative, it is intended to provide further instruction to the application.Unless another It indicates, all technical and scientific terms used herein has usual with the application person of an ordinary skill in the technical field The identical meanings of understanding.

It should be noted that term used herein above is merely to describe specific embodiment, and be not intended to restricted root According to the illustrative embodiments of the application.As used herein, unless the context clearly indicates otherwise, otherwise singular Also it is intended to include plural form, additionally, it should be understood that, when in the present specification using term "comprising" and/or " packet Include " when, indicate existing characteristics, step, operation, device, component and/or their combination.

It as background technique is introduced, rotary torsion exists in the prior art easily causes and deform unstable deficiency, be Solution technical problem as above, present applicant proposes the collet-type numerical control knife handles that a kind of non-threaded gap and torsion deform.

In a kind of typical embodiment of the application, as Figure 1-Figure 2, a kind of non-threaded gap and torsion are provided The collet-type numerical control knife handle of deformation, including knife handle ontology 1, nut housing 2, collet chuck 5, ostium circle 4 and retaining ring 3, wherein cylinder Folder 5 is located at 1 inside end of knife handle ontology.

The circumferential multistage straight platform of positioning of setting in 1 end of knife handle ontology, is equipped with inside nut housing 2 and knife handle ontology 1 Position the straight platform of positioning that straight platform matches.

Preferably, 2 inside of nut housing positions straight platform with setting second order outside knife handle ontology 1.

The cylinder 5 is equipped with groove by the outer circumferential of proximal end, and 4 side of ostium circle is set in groove, and aperture is matched 4 other sides of circle are closed to contact with 2 inner surface of nut housing.

The contact surface of the nut housing 2 and ostium circle 4 is respectively provided with taper, enhances centering.

Retaining ring 3 is set between ostium circle 4 and nut housing 2, by built-in retaining ring 3 by nut housing 2 and aperture Matching ring 4 links together, and prevents from falling off.

Preferably, the retaining ring 3 is made of steel wire.

The ostium circle 4 is handled using partial end-face titanizing, increases wearability, is eliminated collet chuck 5 and is exchanged to nut Damage.

Traditional monoblock type nut is split into the two parts mutually slided by the application, and increases retaining ring 3, the straight platform of positioning, cylinder Folder 5 is being attached to knife handle inner cone locking type by nut band, positions straight platform correction thread pitch, locking is eliminated in the split type rotation of nut Torsion, to achieve the purpose that collet chuck locking type high-precision, high-strength clamping.

The foregoing is merely preferred embodiment of the present application, are not intended to limit this application, for the skill of this field For art personnel, various changes and changes are possible in this application.Within the spirit and principles of this application, made any to repair Change, equivalent replacement, improvement etc., should be included within the scope of protection of this application.
