Specific implementation mode

The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally The every other embodiment that field those of ordinary skill is obtained without making creative work, belongs to this practicality Novel protected range.

It is in the description of the present invention, it should be noted that term "center", "upper", "lower", "left", "right", " perpendicular Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only The utility model and simplifying describes for ease of description, do not indicate or imply the indicated device or element must have it is specific Orientation, with specific azimuth configuration and operation, therefore should not be understood as limiting the present invention.In addition, term " the One ", " second ", " third " are used for description purposes only, and are not understood to indicate or imply relative importance.

In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other Not constituting conflict can be combined with each other.

Fig. 1 is the stereoscopic schematic diagram that milling cutter is covered according to a kind of PCD of the utility model one embodiment.PCD covers milling cutter one As property include cutter head 1 and handle of a knife 2.Handle of a knife 2 is general BT30 handle of a knifes.

Cutter head 1 includes head 11 and interconnecting piece 12, and head 11 is for installing cutter tooth, and interconnecting piece 12 is for connecting cutter head 1 On handle of a knife 2.Interconnecting piece 12 is diameter and handle of a knife 2 close to the comparable cylinder of 1 end face diameter of cutter head.

Head 11 includes the disk 111 being arranged in 12 one end of interconnecting piece, and disk 111 is on its surface far from handle of a knife 2, certainly The table of its periphery convexes to form a cycle basis bottom 112 away from 2 direction of handle of a knife, and substrate 112 is for filling cutter tooth.It is leaned in substrate 112 The radially inner side of nearly disk 111 is provided with the first cutter tooth 13, and 13 quantity of the first cutter tooth is 2, and offside is arranged in substrate 112, Namely on rotation round, about 180 ° on the basis of the center of circle are symmetricly set in substrate 112.In substrate 112 far from disk 111 Radially inner side be provided with the second cutter tooth 14, the quantity of the second cutter tooth 14 is 2, in substrate 112 offside be arranged, that is, On rotation round, about 180 ° on the basis of the center of circle are symmetricly set in substrate 112.First cutter tooth 13 and the second cutter tooth 14 interval are set It sets, this advantageously ensures that stress balance degree when PCD covers milling cutter rotation operation.Two the first cutter tooth 13 offsides in substrate 112 Be arranged and two the second cutters tooth 14 in substrate 112 offside setting also for improve PCD cover milling cutter rotation operation when by Dynamic balance degree.First cutter tooth 13 is radially inwardly projecting at close 111 end of disk, and such as protrusion 131 in Fig. 1, the second cutter tooth 14 is along axis To substrate 112 is stretched out, these are provided with conducive to the complicated workpiece of processing.

Close to the first cutter tooth 13, chip-removal hole 15,15 side of chip-removal hole are offered in substrate 112（One far from handle of a knife 2 Side）Substrate 112 be continuous, that is, as in Fig. 1 part of substrate 1121 be continuous, this advantageously ensures that the strong of cutter head 1 Degree.The rake face of first cutter tooth 13 is used to be discharged the cutting of the first cutter tooth 13 towards chip-removal hole 15, chip-removal hole 15.Close to the second knife Tooth 14, offers chip space 16 in substrate 112, and chip space 16 is recessed from end of the substrate 112 far from handle of a knife 2 to 2 direction of handle of a knife It falls into.The rake face of second cutter tooth 14 is used to be discharged the cutting of the second cutter tooth 14 towards chip space 16, chip space 16.

In the present embodiment, by structure design as above, good surface smoothness and longer cutter life, ruler can be realized It is very little more to stablize.Special cutter structure avoids the generation of vibration cutting.PCD covers the structure design of milling cutter, when due to processing The reasons such as arm of force shortening can improve cutter rigidity, realize and stablize cutting.

In the present embodiment, since the first cutter tooth 13 and the second cutter tooth 14 are arranged at the radially inner side of substrate 112, Ye Ji The first cutter tooth 13 and the second cutter tooth 14 are arranged on the inner ring of cutter head 1, and outer circle and the week of the inner ring workpieces processing of milling cutter are covered using PCD Slot, compared to universal cutter using outer ring around 70% or more Milling Machining saving of time.

Above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with technique Personage can understand the content of the utility model and implement according to this, the scope of protection of the utility model can not be limited with this, It is all according to equivalent change or modification made by the spirit of the present invention essence, should all cover the scope of protection of the utility model it It is interior.
