Description

But the multiple-edged boring tool of adjusted in concert external diameter
Technical field
The cutter that the present invention relates to use in the machining specifically, but is the multiple-edged boring tool of adjusted in concert external diameter.
Background technology
Existing boring cutter, when regulating blade external diameter size, majority is that single blade is regulated singly.Like this, want the external diameter of each blade is adjusted to equally size, need to take a long time during adjusting.And after the external diameter of some blades was adjusted and compressed with lock-screw, slight variation often can occur again in the external diameter of this blade.Therefore, be difficult to adjust the external diameter of each blade in full accordly.
Summary of the invention
The objective of the invention is to design a kind of Novel boring cutter, so that when regulating the blade external diameter, can adjusted in concert.
The present invention realizes purpose of design like this.
Produce the lower knife body 17, nonstandard cutter holder 19, upper knife body 21 and the governor motion that link to each other with handle of a knife.Be processed with the screw 1 that compresses upper knife body at the upper end of lower knife body 17 end face; The equally distributed groove 2 identical with the blade number; The middle part of lower knife body 17 is processed with locating hole 3.Be processed with lower convex platform 13 in the bottom of nonstandard cutter holder 19, rearward end is processed with trapezoidal end face 12, and leading section is processed with the axial identical fine setting of nonstandard cutter holder 19 and supports screw 9; In the upper front end of nonstandard cutter holder 19, by insert retention screw 11 blade 10 is installed.Process the upper surface screw 5 of stepped hole 6 and the nonstandard cutter holder of compression at upper knife body 21, the centre is processed with installing hole 8; That the side processes is equally distributed, from the axle center to ambient radiation, identical with blade number cutter groove 4 and the milling side 7 that equates with cutter groove 4 quantity, be processed with the screw that can be screwed into nonstandard cutter holder lateral surface compressing screw 16 on each milling side 7.Governor motion includes conical surface regulating block 24 and the spring 25 that adjustment screw 23, spline nut 22 and tapering with scale match with the trapezoidal end face 12 of nonstandard cutter holder 19.
Use when of the present invention, can drive conical surface regulating block 24 upwards or move down by adjustment screw 23.Spring 25 promotes 24 risings of conical surface regulating block when conical surface regulating block 24 moves up.At this moment, the trapezoidal faces of the conical surface of conical surface regulating block 24 and trapezoidal end face 12 drives each nonstandard cutter holder 19 outwards mobile synchronously, so that the blade external diameter increases.When conical surface regulating block 24 moved down, nonstandard cutter holder 19 inwardly promoted each nonstandard cutter holder 19, so that the external diameter of blade diminishes under the effect of each centripetal spring 18.
The present invention can adjusted in concert blade external diameter.Because there is spline nut 22 to eliminate the gap error of screw thread transmission, so precision is high, effective; Because the fine setting of fine setting supporting screw 20 being arranged, can guarantee that nonstandard cutter holder 19 adjusts separately, thus the assurance machining accuracy.

The specific embodiment
Below in conjunction with accompanying drawing, a non-limiting examples is illustrated; The present embodiment is take 3 blades as example.
Produce 1 lower knife body 17(with handle of a knife referring to Fig. 1), 3 nonstandard cutter holder 19(are referring to Fig. 4), 1 upper knife body 21(is referring to Fig. 3) and 1 group of governor motion (referring to Fig. 1).
Referring to Fig. 2.Be processed with 3 screws 1 that can compress upper knife body at the upper end of lower knife body 17 end face; 3 equally distributed grooves 2; The middle part of lower knife body 17 is processed with 1 cylindrical locating hole 3.
Referring to Fig. 3.Process 3 stepped holes 6 and 3 upper surface screws 5 that compress nonstandard cutter holder at upper knife body 21,1 installing hole 8 of processing in the middle of upper knife body 21; The side process 3 equally distributed, from the axle center to cutter groove 4 and 3 milling sides 7 of ambient radiation; 1 screw that can be screwed into nonstandard cutter holder lateral surface compressing screw 16 of processing on each milling side 7.
Referring to Fig. 4. be processed with 1 lower convex platform 13 in the bottom of each nonstandard cutter holder 19, rearward end is processed with trapezoidal end face 12, and leading section is processed with the axial identical fine setting of nonstandard cutter holder 19 and supports screw 9; In the upper front end of each nonstandard cutter holder 19, by insert retention screw 11 1 blade 10 is installed.
