Detailed description of the invention
Describe embodiments of the present invention in detail below with reference to drawings and Examples, to the present invention, how application technology means solve technical problem whereby, and the implementation procedure reaching technique effect can fully understand and implement according to this.It should be noted that, only otherwise form conflict, each embodiment in the present invention and each feature in each embodiment can be combined with each other, and the technical scheme formed is all within protection scope of the present invention.
Specifically, as illustrated in fig. 1 and 2, the invention discloses a kind of cutter, the part that this cutter will be processed is, cylindrical bus is circular arc, tangent with rectilinear generatrix.Wherein, the track of point of a knife is first along rectilinear generatrix walking, goes to circular arc portion and automatically walks out arc track.For this reason, this cutter is made up of three parts, simulation rotating mechanism, and auto-feed structure, rotates and slip switching mechanism.
Wherein, described simulation rotating mechanism, be contained on cover kickstand 10, specifically comprise: a blade 20, be arranged on a rotating disk 30, a fork 40 is rigidly connected with rotating disk 30, and synchronous axial system, one push rod 50 is slidably connected by bearing pin 63 with fork 40, and the push rod other end and end cap 72 are rigidly connected.
Further, preferably, described auto-feed structure, comprise: a handle of a knife 60, described handle of a knife 60 has the first coaxial die cavity 62, and slide-bar 65 is loaded in the first die cavity 62, the second die cavity 67 is had in slide-bar, Compress Spring 66 is loaded in the second die cavity 67, and key 20 is loaded in the chute 68 of slide-bar 65 through handle of a knife 60, and end cap 72 is arranged on handle of a knife 60.
Further, preferably, described rotation and slip switching mechanism, comprising: a thrust bearing 80, with radial bearing 85 combine be loaded on support 10 die cavity in, a bearing pin 90 is contained in two bearings and keeps coaxial.
Be described in detail to operation principle of the present invention below, specifically, the handle of a knife 60 of this cutter, clamping is on boring and milling machine main shaft.During work, cutter moves on to workpiece 22 face of cylinder endpoint location, sees Fig. 3 a, starts axial feed.
At this moment, the thrust of spring is greater than the axial thrust load of cutting force, and spring 66 is not compressed, and circular arc quadrantal points position gone to straight by cutter, sees Fig. 3 b, and bearing pin 90 touches the surface of workpiece 22.Now, bearing pin 90, cover kickstand 10, slide-bar 65, remain static at axis direction, but, handle of a knife 60 moves on end cap 72, spring 66 is just given compression by this, and push push rod 50 simultaneously and advance, push rod 50 promotes fork 40 and rotates, thus rotate with rotating disk 30, blade 20 simultaneously, simultaneously, boring cutter is rotating around main-shaft axis, and bearing group makes revolving part and static workpiece 22 form organic docking in these actions.When point of a knife 20 turns over 90 degree, this working angles completes.Main shaft retreats with handle of a knife 60, and spring 66 returns to original state, continues to retreat, and bearing pin 90, cover kickstand 10, slide-bar 65 all get back to initial position.Withdrawing completes, and namely completes one-period and sees, Fig. 3 c.
After this invention takes such scheme, it is adding man-hour to part, and point of a knife running orbit is circular arc, and by the face of cylinder and circular arc conical surface cutting at one time, automatically completes.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
