The specific embodiment
Referring to figs. 1 through Fig. 3, the utility model is a kind of processes the cutter that spherical cambered surface is used, comprise cutter head 10 and be articulated in the interior knife bar spare 20 of cutter head 10, an end of knife bar spare 20 stretches out cutter head 10, is provided with to drive the driving mechanism that knife bar spare 20 rotates around pin joint in cutter head 10.
The cutter that this processing spherical cambered surface is used drives knife bar spare 20 around its pin joint rotation by controlling driving mechanism work, make knife bar spare 20 ends make the arc track motion, and then do the cambered surface cutting on the inner hole of workpiece surface, process interior spherical cambered surface, simple in structure, easy to operate.
The Cutting tool installation manner that this processing spherical cambered surface is used can be used as lathe tool and uses on lathe, in like manner, be arranged on and can be used as the boring cutter use on boring machine.
If when using as boring cutter, cutter head 10 self rotating belt moving knife rod member 20 is done the circumference cutting movement, control again driving mechanism work and drive knife bar spare 20 around its pin joint rotation, under the acting in conjunction that its pin joint rotates, knife bar spare 20 cuts out interior spherical cambered surface as cambered surface at the gyration of cutter head 10 and knife bar spare 20 self.
If when using as lathe tool, cutter head 10 directly is fixedly mounted on lathe, workpiece is by the action of the work spindle band on lathe gyration, driving mechanism work drives knife bar spare 20 and rotates around its pin joint, under the acting in conjunction that its pin joint rotates, knife bar spare 20 cuts out interior spherical cambered surface as cambered surface at the gyration of workpiece self and knife bar spare 20 self.
As preferred embodiment of the present utility model, driving mechanism comprises that an end is articulated in connecting rod 31 on knife bar spare 20, is hinged with connecting rod 31 other ends and can be along cutter head 10 sliding shoe 32 in axial sliding, and the pull bar 33 that is connected with sliding shoe 32.
As preferred embodiment of the present utility model, knife bar spare 20 comprises rolling disc 21 and the knife bar 22 of being located on rolling disc 21, and an end of knife bar 22 stretches out cutter head 10 and is provided with cutter grain 23, and driving mechanism drives rolling disc 21 and rotates around its center of circle.
in the present embodiment, cutter head 10 is a multidiameter shape, rolling disc 21 is articulated in cutter head 10 take its center of circle as pin joint, radially have a conduit at rolling disc 21, knife bar 22 is installed in conduit, one end of knife bar 22 stretches out cutter head 10, connecting rod 31 is articulated in rolling disc 21 outer rim ends, make rolling disc 21 under the pulling of connecting rod 31, rolling disc 21 can rotate around its center of circle, and then drive knife bar 22 swings, make the cutter grain 23 on it make the cutting of arc track, connecting rod 31 is mainly driven by sliding shoe 32 and pull bar 33, pull bar 33 seesaws along cutter head 10 axis, and then drive sliding shoe 32 in cutter head 10 interior front and back slip, thereby pull connecting rod 31 to move forward and backward, driving rolling disc 21 rotates.
