Abstract
The utility model relates to a boring cutter used in the mechanical process, which makes the original arbor of the boring cutter sepatated into a cutter body part (4) and a cutter setting part (3). The cutter setting part (3) is inserted into the guide hole of the cutter body part (4) and is fastened by a fastening screw (5). The outer circumference at the connecting position of the cutter body part (4) and the cutter setting part (3) is engraved with the scale lines (6) and (10). So when the screw (5) is unlocked, the cutter setting part (3) can rotate a certain angle relatively to the cutter body part (4), and the corner of the blade (2) on the cutter setting part (3) aligns the direction of the main shaft with non-sensitivity error. Consequently, the part ovality error caused by the error of the main shaft of the machine is eliminated.
Description
The utility model relates to the boring cutter that a kind of relevant machining is used.
Existing boring cutter generally all comprises cutter hub part 4 and dress cutter part 3, blade 2, and trip bolt 1 is processed with dress tool bore 9 on the dress cutter part 3, and blade 2 is contained in the tool bore 9, and tightens up with trip bolt 1, and cutter hub part 4 is an integral body with dress cutter part 3.This kind cutter, when mounted, the error that is difficult to point of a knife is adjusted to machine tool chief axis is sensitive direction least, therefore, the deviation from circular from of part when the numerical value of the widely different commentaries on classics error of machine tool chief axis warp-wise just is reflected as bore hole to some extent during bore hole, and numerical value is very unstable, can't stably reach the desired precision of circularity of part, thereby not guarantee the part precision requirement.
The purpose of this utility model is to provide a kind of boring cutter, can eliminate by the caused part deviation from circular from of the radially widely different commentaries on classics error of machine tool chief axis.
Solution of the present utility model is that cutter hub part and dress cutter are partly made separated two parts, the dress cutter is partly inserted in the pilot hole of cutter hub part, tighten up with trip bolt, partly with on the excircle of adorning cutter part junction be carved with 360 ° reticule at cutter hub, on dress cutter part, be carved with a groove, like this, unclamp trip bolt, just can be with dress cutter part with respect to a certain angle of cutter hub partial rotation, make the point of a knife of the blade on the dress cutter part aim at the least responsive direction of lathe spindle error, thereby eliminate the caused part deviation from circular from of machine tool chief axis error.
The utility model comprises the cutter hub part, dress cutter part, blade, trip bolt, the dress cutter partly is processed with the dress tool bore, blade is contained in the tool bore, and tighten up with trip bolt, of the present utility modelly be characterised in that cutter hub part and dress cutter partly are separated two parts, on the cutter hub part, be processed with pilot hole and steam vent, the dress cutter partly inserts in the pilot hole of cutter hub part, and tighten up with trip bolt, being carved with 360 ° reticule on the cutter hub part with on the excircle of dress cutter part junction, on dress cutter part, be carved with a groove, unclamp trip bolt, can dress cutter part is arbitrarily angled with respect to the cutter hub partial rotation.
Accompanying drawing is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model as shown in drawings, it comprises cutter hub part 4, dress cutter part 3, blade 2, trip bolt 1, dress cutter part 3 is processed with dress tool bore 9, blade 2 is contained in the tool bore 9, and tighten up with trip bolt 1, it is characterized in that cutter hub part 4 and dress cutter part 3 are separated two parts, be processed with pilot hole 8 and steam vent 7 on cutter hub part 4, dress cutter part 3 is inserted in the pilot hole 8 of cutter hub part 4, and tightens up with trip bolt 5, be carved with 360 ° reticule 6 on the cutter hub part 4 with on the excircle of adorning cutter part 3 junctions, on dress cutter part 3, be carved with a groove 10, unclamp trip bolt 5, can dress cutter part 3 is arbitrarily angled with respect to 4 rotations of cutter hub part.Dress cutter part 3 forms with No. 45 steel machinings of cutter hub part 4 usefulness, and carries out modifier treatment and blackout processing; The trip bolt standard component, the dress tool bore 9 on the dress cutter part 3 is a square hole, blade 2 is contained in the tool bore 9, and tightens up with trip bolt 1, by boring cutter being installed shown in the accompanying drawing.Before bore hole, measure the direction of widely different commentaries on classics error between the maximum diameter that machine tool chief axis produces earlier, the sensitive direction of the error when this direction is bore hole.During bore hole the handle of a knife on the cutter hub part 4 of this boring cutter is inserted in the tapered bore of machine tool spindle with either direction, then two trip bolts 5 are unclamped, rotation is clamped in the blade 2 on the dress cutter part 3, make the most responsive direction of point of a knife alignment error of blade 2, at this moment, firmly believe the value of 360 ° reticule on the cutter hub part 4 that the groove 10 on the dress cutter part 3 aimed at, then, press 360 ° reticule numerical value on the cutter hub part 4, will adorn cutter part 3 half-twists, make the least responsive direction of point of a knife alignment error, to adorn cutter part 3 with trip bolt 5 again and tighten up, just can process, at this moment, the hole that processes, its deviation from circular from minimum.
The utility model is simple in structure, and cost is low, and is easy to use, and with the part after the processing of this kind boring cutter, its error can reduce about 1 times, has improved the crudy of part widely.
Be below on same T68 boring machine, same test specimen processed the control wells of two groups of φ 50mm with same cutting data.The maximum difference of this lathe through checking its radially widely different commentaries on classics error stabilizes to 25 μ m, and the direction of the maximum of its radially widely different commentaries on classics error and minimum of a value is stable, shown in subordinate list.
Subordinate list:
| Error when point of a knife is adjusted to the sensitive direction bore hole of error.(representing original boring cutter) | With 90 ° of the widely different commentaries on classics of point of a knife, adjust to the least error during the sensitive direction bore hole of error.(representative the utility model) |
