Description

A kind of combination cutter with six cutting edges

Technical field

The utility model belongs to machining tool technical field, and in particular to a kind of composite hinge with six cutting edges Knife.

Background technology

Currently, in the processing to multigroup stepped hole in part, multigroup hole division of labor step Milling Machining is mostly used, to required precision Higher hole need to use multigroup boring cutter to distinguish Boring；Two groups of holes are processed respectively by two boring cutters, and after each tool changing, there are knives Have clamping error, step depth can be caused inconsistent, especially step junction has machined trace, arc transition not round and smooth；Effect In terms of rate：Two groups of holes are processed respectively by two boring cutters, need to carry out tool changing twice, the dead time is more, and processing efficiency is low.

Invention content

The utility model provides a kind of combination cutter with six cutting edges for the drawbacks described above of the prior art.

The purpose of this utility model is achieved through the following technical solutions：

A kind of combination cutter with six cutting edges, includes the knife bar of cutter head and cylindrical structure；The cutter head and institute Knife bar is stated to be integrally formed using hard alloy；The cutter head is coaxially disposed with the knife bar；Even circumferential is arranged on the cutter head There are six cutting edges and chip space, the cutting edge and chip space to be separately arranged；The cutter head from far from the knife bar one It holds, is provided with the first knife face and the second knife face from left to right；Right angle transition between first knife face and second knife face； Angle between the two neighboring cutting edge non-working surface and working face is 70 °；Each cutting edge working face top Angle of inclination be 20 °.

Further, the opposite handle of the cutting blade of first knife face and second knife face bounce is within 0.005；The knife bar The opposite handle of outer circle bounce is within 0.005.

Further, the cutter head and the diameter for the part that the knife bar connects are identical as the diameter of the knife bar.

Compared with prior art, the utility model has at least the following advantages：

The combination cutter with six cutting edges of the utility model, from cutter head from one end far from the knife bar, from Left-to-right is provided with diameter the first knife face and the second knife face incremented by successively；When to multigroup step hole machined, it is processed and formed at one time, Reduce processing course error, there is no step circular arc machined trace, each step dimension is more precisely consistent；Once complete two groups of holes Processing, reduces tool change time and cutter dry running time, is improved significantly in processing efficiency.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all Embodiment.

Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts The every other embodiment obtained, shall fall within the protection scope of the present invention.

It is to be appreciated that the directional instruction of institute in the utility model embodiment（Such as up, down, left, right, before and after ...） It is only used for explaining in a certain particular pose（As shown in the picture）Under relative position relation, motion conditions etc. between each component, such as When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.

The description for being such as related to " first ", " second " in the present invention is used for description purposes only, and should not be understood as It indicates or implies its relative importance or implicitly indicate the quantity of indicated technical characteristic.Define as a result, " first ", The feature of " second " can explicitly or implicitly include at least one of the features.

In the description of the present invention, the meaning of " plurality " is at least two, such as two, three etc., unless otherwise Clear specific restriction.

In the present invention unless specifically defined or limited otherwise, term " connection ", " fixation " etc. should do broad sense reason Solution, for example, " fixation " may be a fixed connection, may be a detachable connection, or integral；It can be mechanical connection, also may be used To be electrical connection；It can be directly connected, can also can be indirectly connected through an intermediary the connection inside two elements Or the interaction relationship of two elements, unless otherwise restricted clearly.It for the ordinary skill in the art, can be with The concrete meaning of above-mentioned term in the present invention is understood as the case may be.

In addition, the technical solution between each embodiment of the utility model can be combined with each other, but must be with ability Domain those of ordinary skill can be implemented as basis, will be understood that when the combination of technical solution appearance is conflicting or cannot achieve The combination of this technical solution is not present, also not within the protection domain of the requires of the utility model.

As shown in Figure 1 and Figure 2, a kind of combination cutter with six cutting edges, includes the knife of cutter head 1 and cylindrical structure Bar 2；The cutter head 1 is integrally formed with the knife bar 2 using hard alloy；The cutter head 1 is coaxially disposed with the knife bar 2；Institute It states even circumferential on cutter head 1 and is provided with six cutting edges 3 and chip space 4, the cutting edge 3 and chip space 4 are separately arranged；Institute Cutter head 1 is stated from one end far from the knife bar 2, is provided with the first knife face 5 and the second knife face 6 from left to right；First knife Right angle transition between face 5 and second knife face 6；Angle between two neighboring 3 non-working surface of the cutting edge and working face It is 70 °；The angle of inclination on each 3 working face top of the cutting edge is 20 °.
