Specific embodiment

For the ease of understanding the utility model, with reference to the accompanying drawings and detailed description, the utility model is carried out more Detailed description.It should be noted that it can be directly in another element when element is expressed " being fixed on " another element Upper or placed in the middle there may be one or more therebetween elements.When an element is expressed " connection " another element, it can To be directly to another element or elements placed in the middle there may be one or more therebetween.This specification is used Term " on ", "lower", "inner", "outside", the instructions such as " bottom " orientation or positional relationship be orientation based on the figure or Positional relationship is merely for convenience of describing the present invention and simplifying the description, rather than the device or member of indication or suggestion meaning Part must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention. In addition, term " first ", " second " " third " etc. are used for description purposes only, it is not understood to indicate or imply relatively important Property.

Unless otherwise defined, technical and scientific term all used in this specification and the skill for belonging to the utility model The normally understood meaning of the technical staff in art field is identical.Art used in the description of the utility model in this specification Language is only for the purpose of describing specific embodiments, and is not intended to limitation the utility model.Art used in this specification Language "and/or" includes any and all combinations of one or more related listed items.

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.

As shown in Figure 1 to Figure 3, the cutter that drills and reams in one preferred embodiment of the utility model includes cutter head 1 and knife bar 2, Cutter head 1 is connect with knife bar 2, and knife bar 2 clamps rear fixed cutting tool for equipment, and cutter head 1 is equipped with end sword 11 far from one end of knife bar 2.

In the present embodiment, cutter head 1 includes two the first lands 12 being evenly spaced in outer ring along axial direction, preferably Ground, two the first lands 12 are distributed in the outer ring of cutter head 1 along axisymmetrical, guarantee stress balance.

First land 12 axially extends setting, is formed with cutter groove 13, cutter groove between every two the first adjacent lands 12 13 axially extend setting.First land 12 and the axially extending setting of cutter groove 13, allow 13 two sides of cutter groove the first land 12 side Edge is also axially disposed, so that drilling and reaming cutter in processing, the two edges of the first land 12 can be to the inner wall of the inner hole of processing Face is cooperated to, its stress point is more more when processing, is allowed stress more to balance, can be reduced vibration when tool sharpening, makes to bore It is more stable to cut with scissors work in-process, to improve the finish of cutter life and product.The final effect of the cutter that drills and reams is not increase Client's cutter use cost is reduced in the case where adding production cost, promotes consumer product finish and competitiveness.

In other embodiments, the quantity of the first circumferentially distributed land 12 of 1 outer ring of cutter head can also be more than two Other quantity.The position of the quantity and the first land 12 of holding sword 11 corresponds, convenient for cutting the transmitting with power.

It is respectively formed with secondary land 14 between the two edges of first land 12 and adjacent cutter groove 13, secondary land 14 is along axial direction It is extended.

In the present embodiment, the first land 12, secondary land 14 are plane, secondary land 14 and the first land 12 and cutter groove 13 Side wall surface 131 be in angle, allow two secondary lands 14 on the first land 12 and both sides to combine the land for forming bar shape.Secondary sword Band 14 the wide increasing of 13 arc of cutter groove, two of both sides secondary lands 14 make in the case where not increasing tool blade number cutter by Power direction increases 4 from 2, and cutter is more stable, and the finish of the product of processing is also more good.

In other embodiments, it can also be only formed between a wherein edge and adjacent cutter groove 13 for the first land 12 Secondary land 14.

Cutter groove 13 includes the two side walls face 131 in angle, and cutter groove 13 extends to knife bar 2, and at least one of cutter groove 13 Side wall surface 131 to 13 outside sweep of cutter groove and extends to the outside wall surface of knife bar 2 close to one end of knife bar 2, and cutter groove 13 is allowed to extend to knife The outside wall surface of bar 2, curved curved-surface structure can promote the intensity of cutter.

Preferably, in the present embodiment, 131 included angle of two side walls face of cutter groove 13 is 120 ± 5 °, in other implementations In example, 131 included angle of two side walls face of cutter groove 13 can also be other angles, and the section shape of cutter groove 13 can also be C-shaped, U The shapes such as shape, V-arrangement.

Specific embodiment of the present invention is by by the first land and the axially extending setting of cutter groove, allowing the of cutter groove two sides The edge of one land is also axially disposed, so that drilling and reaming cutter in processing, the two edges of the first land can be in processing The inner wall in hole is cooperated to, its stress point is more more when processing, is allowed stress more to balance, can be reduced shake when tool sharpening Dynamic, the work in-process that makes to drill and ream is more stable, to improve the finish of cutter life and product.In the feelings for not increasing production cost Client's cutter use cost is reduced under condition, promotes consumer product finish and competitiveness.

It is to be appreciated that above-mentioned each technical characteristic can be used in any combination and unrestricted.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other related technical areas are also included in the patent protection scope of the utility model.
