Description

Taper connects knife handle

Technical field

The utility model relates to processing center machine tool cutting-tool engineering fields, connect knife handle more particularly, to a kind of taper.

Background technique

Traditional small-diameter cutter, substantially all using ER collet chuck or strength collet chuck or other transformational structure clamp-on tool come Process part.But due to the structure problem of most part to be processed, the space that can accommodate cutter is limited, always to lengthen small straight The length of diameter cutter meets processing request, and cutter draw ratio increase will affect the rigidity of cutter, and occurs shaking and knife or add The problems such as drawing requirement is not achieved in Chinese musical scale cun.

Utility model content

The technical issues of the utility model solves is that the length increase of small-diameter cutter in the prior art can be in process Drawing requirement is not achieved in middle appearance vibration knife or processing dimension.

In order to solve the above technical problems, technical solutions of the utility model provide a kind of taper connection knife handle, wherein including Holder main body, the holder main body are the trapezoidal pole piece in longitudinal section, the end of the holder main body integrally formed with knife bar, The end of the knife bar is equipped with blade, wherein the holder main body is equipped at least one rotation slot in the longitudinal direction.

Optionally, the end of the knife bar offers the blade mounting groove for installing the blade.

Optionally, it is through with axis inlet opening on the axial direction of the connection knife handle, the knife handle is run through in the inlet opening Main body and the knife bar.

Optionally, apopore is equipped between the inlet opening and the blade mounting groove.

Optionally, the tail portion of the holder main body has post-tensioning power transmission face.

Optionally, outside diameter of the holder main body close to post-tensioning power transmission face one end is less than the holder main body and leans on The outside diameter of nearly described knife handle one end.

Optionally, the rotation slot number is three, and is uniformly distributed on the holder main body.

The beneficial effect of technical solutions of the utility model is:

The utility model, when connection knife handle is clamped by packaged clamp, is passed through by increasing rotation slot on holder main body Key and rotation slot in packaged clamp cooperate, and prevent the radial rotating that knife handle is connected in process.Pass through the knife of taper simultaneously Handle main body, so that connection knife handle and packaged clamp are more convenient when assembling.

Detailed description of the invention

Fig. 1 is the structural schematic diagram that taper connects knife handle in the utility model embodiment；

Fig. 2 is the front view that taper connects knife handle in the utility model embodiment；

Fig. 3 is the assembly schematic sectional view that taper connects knife handle and packaged clamp in the utility model embodiment.

Specific embodiment:

The utility model is described in further detail in the following with reference to the drawings and specific embodiments, but not as the utility model It limits.

In the present invention unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ", " Gu It is fixed " etc. terms shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, can also can be indirectly connected through an intermediary Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood as the case may be Concrete meaning in the present invention.

Referring to Figure 1 and shown in Fig. 2, a kind of taper connection knife handle 100 of embodiment is shown, wherein including knife handle master Body 1, holder main body 1 are the trapezoidal pole piece in longitudinal section, and the end of holder main body 1 is integrally formed with knife bar 2, the end of knife bar 2 Portion is equipped with blade 3, wherein holder main body 1 is equipped at least one rotation slot 4 in the longitudinal direction, preferred in the present embodiment It is 3, and is uniformly distributed on holder main body, is cooperated by the suit head 201 of rotation slot 4 and aftermentioned packaged clamp 200, set The key (not shown) having in head 201 with 4 structure matching of rotation slot is filled, connection knife handle 100 is limited by the cooperation of key and slot Relative to the radial rotating freedom degree of packaged clamp 200, the possibility that vibration knife occurs for cutter in process is avoided.

In the present embodiment, the end of knife bar 2 offers the blade mounting groove 5 for installing blade 3.

It in the present embodiment, connects and is through with axis inlet opening 6 on the axial direction of knife handle, 1 He of holder main body is run through in inlet opening 6 Knife bar 2 is equipped with apopore 7 between inlet opening 6 and blade mounting groove 5, the coolant liquid in process enters from inlet opening 6, warp Blade mounting groove 5 is flowed to by apopore 7.

Shown in Figure 3 in the present embodiment, the tail portion of holder main body 1 has post-tensioning power transmission face 8, for external set clamping Tool 200 is clamped, and is specifically clamped by the folder 202 in packaged clamp.

In the present embodiment, outside diameter of the holder main body 1 close to 8 one end of post-tensioning power transmission face is less than holder main body close to knife handle The outside diameter of one end facilitates the assembly of connection knife handle 100 and packaged clamp 200.

In conclusion the utility model by increasing rotation slot on holder main body, is pressed from both sides when connecting knife handle by packaged clamp When holding, cooperated by the key in packaged clamp with rotation slot, prevents the radial rotating for connecting knife handle in process.Pass through simultaneously The holder main body of taper, so that connection knife handle and packaged clamp are more convenient when assembling.

The above is only the utility model preferred embodiments, are not intended to limit the embodiments of the present invention and protection Range should can appreciate that all with the utility model specification and diagramatic content institute to those skilled in the art The equivalent replacement made and obviously change obtained scheme, the protection scope of the utility model should all be included in It is interior.
