Description
Technical field
The utility model relates to the cutter that uses in the machining, specifically, but is the multiple-cutting-edge boring cutter 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 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 take place again in the external diameter of this blade.Therefore, be difficult to adjust the external diameter of each blade in full accordly.
The utility model content
The purpose of this utility model is a kind of novel boring cutter of design, makes when regulating the blade external diameter, can adjusted in concert.
The utility model is to realize 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, blade 10 is installed by insert retention screw 11.Process stepped hole 6 and the upper surface screw 5 that compresses nonstandard cutter holder on 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 cutter groove 4 and the milling side 7 that equates with cutter groove 4 quantity with the blade number, 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 adjustment screw 23, spline nut 22 and the tapering conical surface regulating block 24 and the spring 25 that match with the trapezoidal end face 12 of nonstandard cutter holder 19 of band scale.
When using the utility model, 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 and outwards moves synchronously, makes the blade external diameter increase.When conical surface regulating block 24 moved down, nonstandard cutter holder 19, inwardly promoted each nonstandard cutter holder 19 entad under the effect of spring 18 at each, makes the external diameter of blade diminish.
The utility model can adjusted in concert blade external diameter.Because have spline nut 22 to eliminate the gap error of screw thread transmission, so the precision height is effective; Because the fine setting of fine setting supporting screw 20 is arranged, can guarantee that nonstandard cutter holder 19 adjusts separately, thus the assurance machining accuracy.
