After manually debugging was finished, lathe can formally come into operation, and the processing work process will all realize automation, and operating personnel are not had specification requirement, and the single operation personnel can control many lathes simultaneously.

In the process that workpiece is processed, the course of work of lathe is as follows:

Workpiece to be processed is positioned in the vibrating disc 64, start lathe work, open vibrating disc starting switch 22, and regulate the brisance of electromagnetic shaker 7 by brisance by-pass cock 21, workpiece is grabbed in the part 37 by the workpiece that conveying 65 is sent into manipulator under the effect of electromagnetic shaker 7.

This moment, headstock 17 inner main axis just changeed, cylinder 1 is opened, assembly 36 is moved on to anchor clamps 16 the place aheads, it is corresponding with anchor clamps 16 positions to make workpiece grab part 37, and assembly 36 touches command switch 32 and opens shift fork cylinder 2 simultaneously, promotes knockout rod 39 workpiece is pushed in the anchor clamps 16, pinch pull bar 100 moves right simultaneously, touch command switch 31 and open pinch spanner cylinder 3, promote pinch pull bar 100 workpiece is clamped, cylinder 1 resets with shift fork cylinder 2.

In this process, operation between the clamping device internal part is: pinch pull bar 100 moves right, driving active 13 moves right, and then drive yoke bracket 75 moves right, pinch 14 is expanded at active 13 place, driving pinch moves right by dish 15, thereby pull bar 77 is moved right, driving anchor clamps 16 moves right, workpiece is clamped, and all associated components reset when pinch pull bar 100 resets, and are adding man-hour, pinch 14 is rotated under the action of centrifugal force at a high speed, pinch 14 opens the easy stuck workpiece that makes can't be loosened, and by back-moving spring 76 is set on pinch 14, prevents the stuck phenomenon when pinch 14 rotates at a high speed, anchor clamps can help anchor clamps 16 to reset by end outer spring 70, and anchor clamps 16 reset rear jig by the end 68 outside workpiece realization automatic blanking that ejects under the effect of inner spring 69.

Meanwhile, pinch pull bar 100 touches command switch 31 can open down planker cylinder 4 simultaneously, 5, at following planker cylinder 4, under 5 the promotion,

cutter

56,57 directly cut workpiece, cutting the laggard cutter stop nut 62 that puts in place contacts with following

planker

10,30 contacts of following planker control instruction switch adjusting screw(rod) 59 and instruction switches, following

planker cylinder

4,5 reset, then command switch adjusting screw(rod) 61 contacts with command switch 29, last planker cylinder 6 is opened, the spacing screw rod 55 of planker 11 and last planker is contacted, with planker cylinder 4 and following planker cylinder 5 are opened at present, planker 10 travels forward under promoting, and when moving to down 30 contacts of planker control instruction switch adjusting screw(rod) 60 and instruction switches, this moment, screw die 53 tapping were finished.

Headstock 17 inner main axis counter-rotating under command switch 30 effects, following

planker cylinder

4,5 resets, following planker 10 resets, last planker cylinder 6 resets, and last planker 11 resets, and command switch adjusting screw(rod) 61 contacted with command switch 29 when following planker 10 resetted, pinch spanner cylinder 3 resets under the effect of command switch 29, pinch pull bar 100 resets, and anchor clamps 16 is loosened workpiece and ejection automatically, machines.
