The specific embodiment
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 also not only confined 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 considered as protection scope of the present invention.
Fig. 1 to Fig. 4 shows one embodiment of the present of invention, and the adjustable cutting tool of tool cutting edge angle of the present embodiment, comprises cutter body 1, cutting tip 3 and adjustment block 51, and cutter body 1 is provided with cutter groove 2, and cutter groove 2 comprises 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 and adjustment block 51 coordinate for plane contact.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 coordinating 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 greater than the radius of adjustment block the first locating surface 511.On cutter body 1, be provided with for driving adjustment block 51 around the actuator of adjustment block housing screw 52 rotations.In the time of need to regulating the tool cutting edge angle of cutting tip 3, by actuator, drive adjustment block 51 around 52 rotations of adjustment block housing screw, due to cutting tip 3 with adjustment block 51 for contacting cooperation, the rotation of adjustment block 51 must drive cutting tip 3 rotation, thereby reaches the object that regulates cutting tip 3 tool cutting edge angles.
In the present embodiment, actuator, for adjusting screw 53, offers the adjustment screw hole 28 that leads to cutter groove side 29 on cutter body 1, adjusts screw 53 and is bolted in adjustment screw hole 28; Adjustment block 51 is provided with for contacting with adjusting screw 53 ends the adjustment face 513 coordinating, and by tightening, adjusts screw 53, can apply motive force to adjustment block 51, promotes adjustment block 51 rotations.
In the present embodiment, cutter groove side 29 is also provided with cutter groove the second locating surface 24, adjustment block 51 is provided with and contacts adjustment block the second locating surface 512 coordinating with cutter groove the second locating surface 24, and adjustment face 513 is 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 greater than the radius of adjustment block the second locating surface 512.
In the present embodiment, cutter groove the second locating surface 24 is concentric arcs face with cutter groove the first locating surface 23, 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 is concentric arcs face with adjustment block the first locating surface 511, 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 is also provided with cutter groove and faces 21 and connect cutter groove and face 21 and face 21 cutter groove empty avoiding faces 22 in a certain angle directly with cutter groove directly directly, and a side of cutting tip 3 and cutter groove are faced 21 directly and contacted to coordinate also and can at the promotion backspin of adjustment block 51, go to cutter groove empty avoiding face 22 and contact cooperation.In the present embodiment, cutter groove face directly 21 and cutter groove empty avoiding face 22 between angle be that α is 30 degree, the tool cutting edge angle of cutting tip 3 can be adjusted on former basis between 0 to 30 degree.
When actual installation, adjustment block 51 is inserted to cutter groove 2 the insides, make 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 adjustment screw 53 being screwed into adjust in screw hole 28 makes it just contact with the adjustment face 513 of adjustment block 51, then adjustment block housing screw 52 is screwed in adjustment block lock-screw hole 514 and adjustment block screw hole 27 and applies a pretightning force to adjustment block 51, guarantee that adjustment block the first locating surface 511, adjustment block the second locating surface 512 contact location with cutter groove side 29, adjustment face 513 contacts location with adjustment screw 53.Then, cutting tip 3 is inserted to cutter groove 2 the insides, make cutting tip 3 one sides and cutter groove face 21 directly and contact cooperation, cutting tip 3 another sides contact cooperation with adjustment block 51; Then blade pressing screw 4 is screwed in blade screw hole 26 and applies a pretightning force to cutting tip 3, guarantee that cutting tip 3 all contacts and locates with adjustment block 51 with cutter groove 2.Then first adjustment block housing screw 52 is screwed under the prerequisite that guarantees adjustment block 51 lockings sequentially, then blade pressing screw 4 is screwed and guarantees cutting tip 3 lockings, just installed cutting tool, referring to Fig. 3.Whether now just can detect cutting tip 3 tool cutting edge angles meets the demands.
In the time of need to adjusting the tool cutting edge angle of cutting tip 3, first blade pressing screw 4 unscrewed but do not screw out blade screw hole 26, make blade in relaxed state, then adjustment block housing screw 52 also unscrewed but do not screw out adjustment block screw hole 27, make adjustment block 51 in relaxed state, now guarantee that adjustment block 51 still contacts with adjustment screw 53 with cutter groove 2, cutting tip 3 still contacts with adjustment block 51 with cutter groove 2.Then by rotation slowly, adjust screw 53, make to adjust screw 53 by and the threaded engagement adjusted between screw hole 28 be subjected to displacement; Because adjustment block is adjusted, face 513 contacts with adjustment screw 53, the radius of cutter groove the first locating surface 23 is greater than the radius of adjustment block the first locating surface 511, the radius of cutter groove the second locating surface 24 is greater than the radius of adjustment block the second locating surface 512, so adjust the displacement of screw 53, will force adjustment block the first locating surface 511 and adjustment block the second locating surface 512 by counter clockwise direction, to rotate on cutter groove the first locating surface 23 and cutter groove the second locating surface 24; Again because cutting tip 3 contacts with adjustment block 51, so will force cutting tip 3 also by counterclockwise rotation when adjustment block 51 is rotated counterclockwise.When cutting tip 3 rotation to need tool cutting edge angle time, at this moment adjustment block housing screw 52 can be screwed exactly and guarantee adjustment block 51 lockings, then blade pressing screw 4 is screwed and guarantees cutting tip 3 lockings, thereby reach the object of adjusting cutting tip 3 tool cutting edge angles.Figure 4 shows that cutting tip 3 rotations extremely contact the schematic diagram while coordinating with cutter groove empty avoiding face 22.
In sum, the cutting tool of the present embodiment, can realize cutter tool cutting edge angle completely from the uninterrupted excursion of continuity of 0 ° to 30 °, but also can realize the precise fine-adjustment of cutter tool cutting edge angle, this has not only improved the recycling rate of waterused of cutter greatly, has also avoided the error of the cutter tool cutting edge angle that produces due to cutter distortion, has improved the stability of cutter, reduce the cost of charp tool, realized the multiplex function of a cutter.
