Further, described pushing mechanism is a screw body, and the screw mandrel of described screw body is fixed in the rotating shaft of described worm gear, and the described first mouse fluted disc is fixed in the rear end of the nut of described screw body; Described driving key is fixed in the described knife rest rotating shaft, offers on the described nut to make the described driving key can only be along the gathering sill of screw axis to translation.
Further, described tool-post structure is provided with the sensor of the monitoring tool-post structure anglec of rotation.
Further, described tool-post structure is provided with eight main shafts.
Technical conceive of the present utility model is: during tool changing, earlier main drive gear is separated with mainshaft gear, start drive motors, worm screw is rotated, worm gear rotates under the driving of worm screw, and screw mandrel begins to rotate, the nut back motion thereby make, and the first mouse fluted disc separates with the second mouse fluted disc under the impetus of nut, when the first mouse fluted disc arrives block piece, move and follow screw mandrel after nut stops and rotating; Under the effect of driving key, the knife rest rotating shaft is followed screw body and is rotated, and when sensor sensing arrives the angle arrival predetermined angle of tool-post structure rotation, makes the drive motors counter-rotating; Nut stops operating, travels forward along the screw mandrel axis direction, up to the first mouse fluted disc and the engagement of the second mouse fluted disc; Mainshaft gear engagement on main drive gear and the main shaft chosen, cutter work.
The utlity model has: need not with tool-post structure jack-up positioning accuracy height, tool-post structure good rigidly, the advantage of long service life.
