Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is described in further detail; should be understood that; protection scope of the present invention is not limited merely to following embodiment; for those skilled in the art; some improvements and modifications without departing from the principles of the present invention, also should be regarded as protection scope of the present invention.
Fig. 1 to Fig. 4 shows one embodiment of the present of invention, the adjustable cutting tool of tool cutting edge angle of the present embodiment, and including cutter body 1, cutting tip 3 and adjustment block 51, cutter body 1 is provided with cutter groove 2, and cutter groove 2 includes cutter groove bottom 25 and cutter groove side 29.Cutter groove bottom 25 is provided with blade screw hole 26 and adjustment block screw hole 27, cutting tip 3 is pressed in cutter groove bottom 25 by blade pressing screw 4, adjustment block 51 is pressed in cutter groove bottom 25 by adjustment block housing screw 52, and cutting tip 3 coordinates for plane contact with adjustment block 51.Cutter groove side 29 is provided with cutter groove the first locating surface 23, adjustment block 51 is provided with and contacts adjustment block the first locating surface 511 coordinated with cutter groove the first locating surface 23, cutter groove the first locating surface 23 and adjustment block the first locating surface 511 are arcwall face, and the radius of cutter groove the first locating surface 23 is more than the radius of adjustment block the first locating surface 511.Actuator for driving adjustment block 51 to rotate around adjustment block housing screw 52 is installed on cutter body 1.When needing the tool cutting edge angle regulating cutting tip 3, adjustment block 51 is driven to rotate around adjustment block housing screw 52 by actuator, due to cutting tip 3 with adjustment block 51 for contacting cooperation, the rotation of adjustment block 51 necessarily drives cutting tip 3 to rotate, thus reaches to regulate the purpose of cutting tip 3 tool cutting edge angle.
In the present embodiment, actuator, for adjusting screw 53, cutter body 1 offers the adjustment screw hole 28 leading to cutter groove side 29, adjusts screw 53 and is bolted in adjustment screw hole 28；Adjustment block 51 is provided with the adjustment face 513 for coordinating with adjustment screw 53 ends contact, by tightening adjustment screw 53, can apply motive force to adjustment block 51, promote adjustment block 51 to rotate.
In the present embodiment, cutter groove side 29 is additionally provided with cutter groove the second locating surface 24, adjustment block 51 is provided with and contacts adjustment block the second locating surface 512 coordinated with cutter groove the second locating surface 24, adjusts face 513 between adjustment block the first locating surface 511 and adjustment block the second locating surface 512.Cutter groove the second locating surface 24 and adjustment block the second locating surface 512 are arcwall face, and the radius of cutter groove the second locating surface 24 is more than the radius of adjustment block the second locating surface 512.
In the present embodiment, cutter groove the second locating surface 24 and cutter groove the first locating surface 23 are concentric arcs face, and the radius of cutter groove the second locating surface 24 is less than the radius of cutter groove the first locating surface 23；Adjustment block the second locating surface 512 and adjustment block the first locating surface 511 are concentric arcs face, and the radius of adjustment block the second locating surface 512 is less than the radius of adjustment block the first locating surface 511.
In the present embodiment, cutter groove side 29 be additionally provided with cutter groove face directly 21 and connect cutter groove face 21 directly and face 21 cutter groove empty avoiding faces 22 in a certain angle directly with cutter groove, the one side of cutting tip 3 face directly with cutter groove 21 contact coordinate and can go to contact cooperation with cutter groove empty avoiding face 22 at the promotion backspin of adjustment block 51.In the present embodiment, cutter groove face directly the angle between 21 and cutter groove empty avoiding face 22 be α be 30 degree so that the tool cutting edge angle of cutting tip 3 can on the basis of former 0 to 30 degree between adjust.
When actual installation, adjustment block 51 is inserted inside cutter groove 2 so that adjustment block first locating surface 511 of adjustment block 51 contacts with cutter groove the first locating surface 23, adjustment block the second locating surface 512 contacts with cutter groove the second locating surface 24.Then it is made just to contact with the adjustment face 513 of adjustment block 51 by adjusting in screw 53 is screwed into adjustment screw hole 28, then a pretightning force is applied to adjustment block 51 in adjustment block housing screw 52 being screwed into adjustment block locking screw nail 514 and adjustment block screw hole 27, ensure that adjustment block the first locating surface 511, adjustment block the second locating surface 512 contact location with cutter groove side 29, adjust face 513 with adjusting screw 53 and contact location.Then, cutting tip 3 is inserted inside cutter groove 2 so that cutting tip 3 one side is faced 21 directly and contacted cooperation with cutter groove, and cutting tip 3 another side contacts cooperation with adjustment block 51；Then a pretightning force is applied to cutting tip 3 in blade pressing screw 4 is screwed into blade screw hole 26, it is ensured that cutting tip 3 all contacts with cutter groove 2 and adjustment block 51 and positions.The most first adjustment block housing screw 52 is screwed on the premise of guarantee adjustment block 51 locks, then blade pressing screw 4 is screwed guarantee that cutting tip 3 is locked, just installed cutting tool, seen Fig. 3.The most just can detect whether cutting tip 3 tool cutting edge angle meets requirement.
When needing the tool cutting edge angle adjusting cutting tip 3, first blade pressing screw 4 is unscrewed but do not screw out blade screw hole 26, blade is made to be in relaxed state, then adjustment block housing screw 52 is also unscrewed but do not screw out adjustment block screw hole 27, adjustment block 51 is made to be in relaxed state, now ensureing that adjustment block 51 still contacts with cutter groove 2 and adjustment screw 53, cutting tip 3 still contacts with cutter groove 2 and adjustment block 51.Then pass through slowly to rotate and adjust screw 53 so that adjust screw 53 and be subjected to displacement by the threaded engagement between adjustment screw hole 28；Due to adjustment block adjust face 513 with adjust screw 53 and contact, the radius of cutter groove the first locating surface 23 is more than the radius of adjustment block the first locating surface 511, the radius of cutter groove the second locating surface 24 is more than the radius of adjustment block the second locating surface 512, so the displacement adjusting screw 53 will force adjustment block the first locating surface 511 and adjustment block the second locating surface 512 to rotate counterclockwise on cutter groove the first locating surface 23 and cutter groove the second locating surface 24；Contact with adjustment block 51 due to cutting tip 3 again, so cutting tip 3 will be forced to rotate the most counterclockwise when adjustment block 51 rotates counterclockwise.When cutting tip 3 rotates to the tool cutting edge angle needed, adjustment block housing screw 52 can be screwed guarantee adjustment block 51 the most exactly and lock, then blade pressing screw 4 is screwed guarantee that cutting tip 3 is locked, thus reach to adjust the purpose of cutting tip 3 tool cutting edge angle.Fig. 4 show cutting tip 3 and rotates to the schematic diagram contacted with cutter groove empty avoiding face 22 when coordinating.
In sum, the cutting tool of the present embodiment, the uninterrupted excursion of continuity that cutter tool cutting edge angle is from 0 ° to 30 ° can be realized completely, but also the precise fine-adjustment of cutter tool cutting edge angle can be realized, this not only substantially increases the recycling rate of waterused of cutter, it also avoid the error of cutter tool cutting edge angle produced by cutter distortion, improves the stability of cutter, reduce the cost of charp tool, it is achieved that the function that a cutter is multiplex.
