Utility model content

For solving the shortcomings and deficiencies of prior art, this utility model provides a kind of V-groove milling cutter, ChengVXing inclined-plane, work piece edge can be processed simultaneously, solve ChengVXing inclined-plane, conventional work piece edge and be difficult to the problem of processing, solve processing simultaneously and do not reach the situation that technology requires.

nullDescribed technical scheme is as follows: this utility model provides a kind of V-groove milling cutter，Including shank、Cutter hub portion，Described shank and cutter hub portion are combined into one，Described shank is cylinder，Described cutter hub portion is positioned at the two ends, left and right of shank，It is characterized in that: described cutter hub portion is that alloy material is made，Circumferencial direction is divided into several teeth，The number of teeth is even number，Tooth is connected with the middle part of tooth，From end face，Each tooth while being inclined-plane，Another side is for facing directly，The angle facing formation directly of the inclined-plane of one tooth and adjacent teeth is chip pocket，On described tooth, the position mill of distance outer face certain distance has V-groove，Two inclined-planes of described V-groove form cutting edge，Before described V-type inclined-plane cutting edge has、Latter two，Before、Rear cutting edge alternately contacts with machined surface，Described tooth is for there being certain thickness laminated structure，Its excircle diameter is identical with shank diameter，Vertically in line，Extend and rounding off to shank for curved type from position, outer face vertically with shank contact site，The top of several teeth described is in a circumference，Top curve self-assembling formation relief angle α.

Become the machining accuracy reaching requirement on V-type inclined-plane in order to solve work piece, the precision of each key position of the V-groove milling cutter that this utility model provides is controlled by.

Preferred as technique scheme, the ligament surface roughness Ra value of the V-type inclined-plane cutting edge of described tooth is not more than 0.2 μm.

Preferred as technique scheme, the Ra value in described cutter hub portion is not more than 0.8 μm.

Preferred as technique scheme, described shank radial run-out≤0.01 to common axis.

The V-groove milling cutter that this utility model provides, the front and back cutting edge of adjacent two teeth of described tooth alternately contacts with machined surface, two inclined-planes on V-type inclined-plane are processed by V-groove cutting edge simultaneously, solve the problem that the complicated oblique surface machinings such as V-type face in electromotor and hydraulic part industry are difficult, improving, the basis of production efficiency also improves machining accuracy, improve import cutter and seriously restrict our province, China's equipment manufacture current situation, improve equipment manufacture level, promote Domestic Cutting Tool, filled the domestic gaps.

Accompanying drawing explanation

In order to be illustrated more clearly that the technical scheme in this utility model embodiment, below the accompanying drawing used required during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the V-groove milling cutter construction schematic diagram front view provided in the present embodiment；

Fig. 2 is the I part local direction view enlarged drawing of Fig. 1.

Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, this utility model embodiment is described in further detail.

nullThis utility model provides a kind of V-groove milling cutter，Such as Fig. 1、Shown in Fig. 2，Including shank 1、Cutter hub portion 2，Described shank 1 and cutter hub portion 2 are combined into one，Described cutter hub portion 2 is positioned at the two ends, left and right of shank 1，It is characterized in that: described cutter hub portion 2 makes for alloy material，It is divided into 4 teeth 4.1 from axially seeing、4.2、4.3、4.4，Each tooth has a straight flange 4.5 and a hypotenuse 4.6，The angle that the hypotenuse 4.6 of tooth and the straight flange 4.5 of adjacent teeth are formed is chip pocket，The middle part of 4 teeth is connected，On 4 described teeth, the position mill of distance end face 5 certain distance has V-groove，Two inclined-planes of described V-groove form cutting edge 6，The V-type inclined-plane cutting edge 6 of described 4 teeth has former and later two，4 described teeth are for there being certain thickness laminated structure，Its excircle diameter is identical with the diameter of shank 1，Vertically in line，Extend and rounding off to shank 1 for curved type from end face 5 position vertically with shank 1 contact site，The top of described 4 teeth is in same circumference，The circular order self-assembling formation relief angle α at top.

For ensureing the machining accuracy on ChengVXing inclined-plane, work piece edge, the geometrical and toleranging of the individual sites of described V-groove milling cutter is controlled by:
