Shown in Fig. 1,2,3,5,6, motor (1) driven gear planet carrier (2) rotation, several compound planet gears (13) that are contained on the gear planet carrier (2) rotate (this moment, this this gear was a sun gear) round the gear 3a on the mechanical coding dish (3), and drive end face cam (4) rotates.Several cam contours 4a on the edge cam (4) descends along several rollers (6), and the disk spring (14) of compression is loosened, brake (22) outage simultaneously, and first alignment pin (23) is upspring.Locking end-toothed disc (7) is under several cylindrical helical springs (11) effect, move backward (because of locking end-toothed disc (7) is connected with casing 12 with feather key, so can not rotate), and throw off with stiff end fluted disc (8), round end fluted disc (9) rapidly, lock several serrate slots 7a and the engagement of several trundles (5) on the edge cam (4) on the end-toothed disc simultaneously, edge cam (4) is pinned.Gear planet carrier (2) continues rotation, several compound planet gears (13) at this moment rotate around the gear 4a on the edge cam (4), (this moment 4b be sun gear), driven wheel 3a, mechanical coding dish (3) rotated simultaneously, and by main shaft (10) driven rotary end-toothed disc (9) and be fixed on the knife rest rotating disk (not shown) rotation of round end fluted disc (9).
As Fig. 1, shown in 2,3, microswitch group (20) drives push rod (15) by the circular-arc raised line on the mechanical coding dish (3) and outwards exports 8421 yards signal.Microswitch closure when selected cutter spacing, with and the microswitch (17) of gating during closed moment, brake (22), handling just, alignment pin (23) inserts forward in the groove of mechanical coding disk (3), mechanical coding dish (3) stops operating, and by main shaft (10) round end fluted disc (9) and knife rest rotating disk is also stopped operating simultaneously.
At this moment gear planet carrier (2) continues rotation, several compound planet gears (13) are around the gear 3a rotation of mechanical coding dish (3), drive end face cam (4) rotates simultaneously, several trundles (6) on the edge cam (4) roll along several serrate slots in locking end-toothed disc (7), and drive it forward with stiff end fluted disc (8), round end fluted disc (9) engagement locking.The engagement while, several cam contours move compression disk spring (14) after several rollers (6) rise also, at the same time, and motor (1) outage, three one group end-toothed disc (7,8,9) clamping, the locking of knife rest rotating disk.
Shown in Figure 6, roller (6) is on the plan-position, cam top of edge cam (4), and end-toothed disc (7,8,9) is in latched position.
Shown in Figure 7, roller (6) is in the cam extreme lower position of face gear (4), and the trundle (5) of edge cam (4) is in the serrate slot of keyed end fluted disc (7), and end-toothed disc (7,8,9) is in the released position.
Fig. 8 is another kind of embodiment of the present invention.As shown in Figure 8, motor (24) rotates through gear train (25) drive end face cam (28), rolling bearing (36) descends along cam curve, the disk spring (33) of compression loosens, locking end-toothed disc (29) is under helical spring (37) effect, several rollers (36) upwards lift along the cam arc groove, and rapidly with end-toothed disc (31), stiff end fluted disc (30) disengagement; Several rollers (35) of edge cam (28) fall into the serrate slot of locking end-toothed disc (29) end face simultaneously, and edge cam (28) is rotated with locking end-toothed disc (29) and capstan head body (27).
As Fig. 9, shown in 11,12, microswitch group (42) is outwards exported 421 code signals according to the angle that the code-disc (26) that is contained on the face gear (28) changes.When the microswitch closure of selected cutter spacing, with and the microswitch (45) of gating during closed moment, brake (38) electric, first alignment pin (41) is depressed, and with and slip in the first detent on the capstan head body (27), capstan head body (27) is tentatively locked.
As shown in Figure 8, locking end-toothed disc (29) is to adopt spline to be connected with capstan head body (27), locking end-toothed disc (29) can only move axially in capstan head body (27), can not rotate, because capstan head body (27) is locked, edge cam (28) continues rotation, and the little roll sleeve of several on it (35) rolls out along the inclined-plane of locking several serrate slots on end-toothed disc (29) end face, and driving locking end-toothed disc (29) meshes with stiff end fluted disc (30) and end-toothed disc (31) downwards.Several cam contours of edge cam (28) move after several rollers (36) rise, compression disk spring (33).At this simultaneously, the microswitch of locking (43) is once closure, motor (24) outage, and several rollers (36) have been on several plan-positions, cams top of edge cam (28), three one group of end-toothed discs (29,30,31) clamping, capstan head body 27 is accurately locked,
Shown in Figure 10, push rod (44) moves up under the driving of mechanical coding dish (26), with the microswitch closure.
