[specific embodiment]
The cutter of the rotation slotting profiled holes of the embodiment of the invention 1 comprises cutter head and anchor clamps.Anchor clamps comprise knife bar 1 and bearing block 2, and the rear end of cutter head 3 is screwed the holding in the hole of knife bar 1 front end 102, and the axle journal 101 at the rear portion of knife bar 1 is installed in the dead eye of bearing block 2 through twice bearing 4 and 5. Bearing 4 and 5 is angular contact bearing (angular contact ball bearings).
The front portion 301 of cutter head 3 is a cutting portion; The cutting portion 301 of cutter head 3 is a back taper; The profiled holes of the profile of the cross section of cutter head 3 front ends and institute's slotting is of similar shape (being hexagon in the present embodiment), and front end face 302 indents of cutter head 3 are to form the anterior angle of cutter head 3 front end face edge cutting edges 303.As shown in the figure, the front end face 302 of indent can be a sphere.
4 mounting screw holes 202 are arranged on the bearing block 2, and the cutter that will rotate the slotting profiled holes through mounting screw is fixed on the bearing of machine tool feed frame.
When the present invention rotated the cutter work of slotting profiled holes (hexagon ring), the clamping workpiece that has prefabricated circular hole was on machine tool chief axis, by the main shaft driven rotary.The bearing block of the cutter of rotation slotting profiled holes is fixed on through 4 screws on the bearing of feeding frame of lathe, and the feeding frame can be along the axial feed of main shaft.
The cutter of rotation slotting profiled holes needs to guarantee the axis of rotation of cutter head 3 and the axis of rotation oblique of machine tool chief axis that the angle of cut α of oblique is 1 ° to 2 ° when mounted.The intersection point of machine tool chief axis axis of rotation and cutter head 3 axiss of rotation is positioned at the central point of cutter head 3 front ends.
In cutter when work,, the feeding frame drives cutter head 3 to the feeding of workpiece direction, and when the workpiece of the preceding end in contact rotation of cutter head 3, the workpiece of rotation drives cutter head 3 and rotate synchronously, and cutter head 3 carries out axial feed when rotating.Cutter head 3 to workpiece direction cutting workpiece, each cutting edge is accomplished the slotting feeding to workpiece in turn cutting forward of work piece surface, on the pre-manufactured hole of workpiece, forms and the identical hexagon ring of cutter head 3 front end face profiles.
In order to prevent that cutter head 3 from interfering in when work and workpiece, the reversed cone angle β of the cutting portion of cutter head 3 is equal to or greater than 2 times of α angles.
The structure that Fig. 4 rotates the cutter embodiment 2 of slotting profiled holes to the present invention of being shown in Figure 7, different with embodiment 1 is, and embodiment 2 also comprises stationary spindle 6, and the front end of stationary spindle 6 is connected through microgroove with bearing block 2 to be fixed.The axis of rotation oblique of the axis of rotation of stationary spindle 6 and cutter head, the angle of cut α of oblique is 1 ° to 2 °.The intersection point of stationary spindle 6 axiss of rotation and cutter head axis of rotation is positioned at the central point A of cutter head front end.
The angle of cut of the axis of rotation oblique of the axis of rotation of present embodiment stationary spindle 6 and cutter head is that the structure through bearing block 2 guarantees.Because bearing block 2 comprises the dead eye 201 of bearing and the installing hole 203 of stationary spindle 6 front ends; Bearing block 2 during fabrication; As long as the axis of dead eye 201 and the axis oblique of installing hole 203, the angle of cut of the axis of the axis of dead eye 201 and installing hole 203 promptly is the angle of cut of stationary spindle 6 axiss of rotation and cutter head axis of rotation.
The length overall γ of cutterhead 3 is a regular length, guarantees that slotting cutter axis of rotation and machine tool chief axis axes intersect are in the center on slotting cutter head 3 tops in use.
