Description
Technical field
The present invention relates to metal cutting process field, particularly relate to the adjustable cutting tool in a kind of cutting tip position.
Background technology
In order to improve the machining accuracy of cutter, especially improving the angle machining accuracy of cutter, having occurred more adjustable-angle cutter in prior art, the general guiding mechanism that adopts adjusts.European patent EP 0471099B1 discloses a kind of machining and rotates class cutting tool, comprise a kind of cutting tip angle-adjusting mechanism: the cuboid adjustment element of similar cutter holder, be with an insert groove, a band bolt hole in the middle part of adjustment element, three adjustment tanks becoming certain relation to arrange, to be pressed in the reconditioner flute on cutter body by bolt hole by fastening bolt; Adjustment tank by the setting and adjustment element side of holding adjustment spheroid endoporus with hold the screwed hole adjusting screw and be connected and form; Cutting tip is anchored in the insert groove of adjustment element by trip bolt; Before adjustment screw, end band bus becomes the conical surface of a upwards acute angle with reconditioner flute side, and adjustment screw is placed in the screwed hole of adjustment tank, and the adjustment spheroid point adjusting the screw conical surface and be placed in adjustment tank endoporus supports; Adjustment spheroid when adjusting can simultaneously with reconditioner flute supporting surface and adjustment screw conical surface point cantact; Due to the existence of above-mentioned acute angle, ensure that under the effect of spanner, screw is rotatable moves up in adjustment, by adjusting the transmission of spheroid, this adjustment screw and cutter body there is relative displacement perpendicular in the corresponding plane adjusting screw axis, due to the existence of hold-down bolt, adjustment element can rotate around bolt hole, by the adjustment of three adjustment screws, adjustment element can reach certain angle change, thus reaches the object to cutting tool machining angle adjustment.
Although this guiding mechanism structure is simple, parts are few, there is shortcoming:
One, described angle-adjusting mechanism utilizes the feature of spheroid equal diameter and centrum external diameter linear change in adjustment principle, in theory, be in course of adjustment, guiding mechanism lateral support is insecure support all the time, greatly reduces the safety and reliability of tool sharpening.
Two, described angle-adjusting mechanism lateral support is a support all the time, in the actual process of cutter, because supporting surface is that minimum point supports, support zone is stress deformation more or less, affect the isodiametric feature of spheroid, and then it is inadequate to cause blade angle to adjust stability, uniformity is poor, repeats Adjustment precision lower.
Three, described angle-adjusting mechanism does not carry out spacing control to adjustment spheroid, when adjusting, the strong point to can be considered on adjustment spheroid arbitrarily random a bit, due to above-mentioned shortcoming two i.e. strong point stress deformation, at secondary or when repeatedly utilizing this adjustment spheroid, adjustment ball position change also nonlinear change, and the possibility that position suddenlys change may be there is, greatly add cutter adjustment difficulty, reduce the adjustment stability of guiding mechanism, the recycling rate of waterused of guiding mechanism parts.
