Four. operation principle of the present utility model.
The utility model cutter is when cutting, the connection situation of each parts is as follows, handle of a knife 10 connects power-equipment by screw 11, clamping sleeve 2 in screwing in the installing hole 91 of tool rest 9, the internal thread of interior clamping sleeve 2 is screwing the following cylinder 53 of micro actuator 5, and (interior clamping sleeve 2 lower ends are compressed by locking plate 1 under the situation that interior clamping sleeve 2 is fixed like this, the upper end heads on knife bar 6 and can't realize axially-movable, therefore can not rotate yet), rotary fine adjustment device 5, interior clamping sleeve 2 can and then not rotate.As long as rotary fine adjustment device 5 just can allow real micro actuator 5 realize axially-movable, last cylinder 51 cooperations of micro actuator 5 are directed in first hole of tool rest 9, play guide effect.The middle frustum of a cone 52 of micro actuator 5 is intersecting with tool bore 8, is provided with two knife bars 6 in the tool bore 8, and the inner inclined-plane 62 of knife bar 6 contacts with the taper seat of the middle frustum of a cone 52, and micro actuator 5 is magnetic, and therefore knife bar 6 can be held servo-actuated; In addition, interior clamping sleeve 2 is under the situation of tightening, and interior clamping sleeve 2 upper surfaces can prevent effectively that knife bar 6 is thrown out of with knife bar 6 being squeezed in the installing hole 91 tightly when rotating.The outer end of knife bar 6 is provided with screwed hole 61, by screw or bolting cutter head 7.Micro actuator 5 lower ends are provided with inner hexagonal hole 54 (can certainly a point of application be set in micro actuator 5 lower ends, be convenient to rotary fine adjustment device 5 and just become), are convenient to rotary fine adjustment device 5.Interior clamping sleeve 2 is compressed by locking plate 1, and flexible cushion rubber 12 between micro actuator 5 and the locking plate 1 mainly is to prevent that micro actuator 5 is loosening.Outside, tool rest 9 lower ends also is provided with anti-skidding trim ring 4 and external compression cover 3 is being pressed, and it is firm more, compact that whole cutter structure becomes.
When needs are regulated cutting output, be to work like this: screw off external compression cover 3, screw off locking plate 1 again, take off flexible rubber ring 12, turn micro actuator 5, micro actuator 5 axially moves, the middle frustum of a cone 52 conical surfaces of micro actuator 5 can promote two knife bars 6 and do radial motion, because micro actuator 5 peripheries are provided with dial, set a normal line on the interior clamping sleeve 2,, can set 5 one weeks of rotary fine adjustment device when datum mark usefulness, therefore the cutting output of a concrete specification of feeding can realize regulating cutting output according to concrete needs.After having regulated, again locking plate 1, external compression cover 3, flexible rubber ring 12 etc. are reinstalled.
Now provide the embodiment of concrete data, the helical pitch L=6mm of micro actuator 5 screw threads, establishing the line number is n=2, pitch p=3mm then, A=9 ° of the middle frustum of a cone 52 conical surfaces and last cylinder 51 axis extended line angle ∠, as shown in Figure 2.Adjuster 5 peripheries are divided equally 100 scales, be about to pitch p and be divided into N=100 part, the corresponding adjusting of each scale axial feeding is L1=3mm/100=0.03mm.Can release according to right angled triangle character: the radial feeds of a scale correspondence of every adjusting are R1=L1*tg9 °=0.03*0.158mm=0.00474mm.Therefore the utility model can rise to the cutting amount of feeding in the 0.005mm, and machining accuracy is higher.Can draw formula a: R1=p*tgA/N from above concrete data,
The utility model comes to this and solves the low technical problem of traditional machine tool machining accuracy.
In addition, the utility model also has other structure except said structure, and also can realize same function, specific as follows shown in.
First point, the utility model installing hole 91 are axially disposed within on the tool rest 9; But situation of change is: installing hole 91 can radially be arranged on the tool rest 9.
Clamping sleeve 2 in second point, the utility model adjusting device adopt and screw in the installing hole 91 is combined with the micro actuator 5 that promotes knife bar 6 radial motions in the interior clamping sleeve 2; But situation of change is: adjuster 5 directly screws with installing hole 91 inwalls and is connected, and tool rest 9 is axially arranged with screwed hole, and screwed hole and tool bore 8 square crossings are tightened from bottom to top by bolt and to be withstood knife bar 6, and knife bar 6 is fixed.
Thirdly, the utility model installing hole 91 screws with interior clamping sleeve 2 and is connected; But situation of change is: can make installing hole 91 and interior clamping sleeve 2 into and adopt and be slidingly connected; Can also make circumferentially spacing mode of installing hole 91 and 2 axially-movables of interior clamping sleeve into, such as being provided with many axial slides in the installing hole 91, interior clamping sleeve 2 outer walls are provided with the axial card article that matches with axial slide number same position correspondingly-shaped.
The 4th point, the utility model are provided with an external compression cover 3 and anti-skidding trim ring 4 in tool rest 9 lower ends, this can save in fact, and also available other modes replace.
The 5th point only is provided with a tool bore 8 on the utility model tool rest 9, be provided with two knife bars 6 in the tool bore 8.But situation of change: a plurality of tool bores 8 and a plurality of knife bar 6 can be set as required.
