Embodiment
See Fig. 1, Fig. 2 and Fig. 3: for arming process in fuzes and the pin removal of valve starting by control mechanism, driving machine Structure and buffer gear composition.
Control mechanism is by front cover 25, guide sleeve 3, sliding block 4, bead 2, big ball 5, plane spring 10,23 and of memory alloy wire Memory alloy wire connector 9 forms.The counter sink of front cover 25 passes through at the major diameter circle convex platform of soket head cap screw 8 and shell 15 Through-hole cooperation, front cover 25 and shell 15 are connected.Fixing screws 6 are solid by the counter sink of 25 bottom plate outer ring of front cover and cylinder outer ring It is fixed, and the socket cap arc groove on the through-hole and drive block 1 on 3 bottom plate of guide sleeve is sequentially passed through, and do not have with socket cap arc groove There is contact;Fixing screws 6 are cased with insulator 7 among the ring up and down of drive block 1, are mounted with that memorial alloy connects on insulator 7 Fitting 9 passes through one end of 9 fixed memory alloy wire of memorial alloy connector.Guide sleeve 3 is mounted on the lower section of front cover 25, and leads to The rectangular teeth and the rectangular channel on shell 15 for crossing 3 outside of guide sleeve position.Drive block 1 is placed in the lower section of guide sleeve 3 and by interior The stepped cylindrical of side is matched with the boss of guide sleeve 3 to be merged and can rotate around guide sleeve 3.The outer ring of plane spring 10 and drive block 1 The slot of lower ring cooperates, and inner ring is placed on 15 partition of shell in the slot of cylinder boss.Bead 2 is mounted on the cylindrical side of guide sleeve 3 In hole, and it can be moved radially in hole.Drive block 4 is mounted between guide sleeve 3 and the boss of front cover 25, if bead 2 and driving The stepped cylindrical of block 1 is tangent, then the multi-diameter shaft rounding of the outer side-lower of sliding block 4 is contacted with bead 2, and sliding block 4 is limited in shell 15 Major diameter annulus top;If bead 2 is jumped into the half slot of 1 inner ring of drive block, the outside of sliding block 4 and bead 2 are tangent, and sliding Block is located in the middle part of the major diameter annulus of shell 15.Big ball 5 is located in the hole of 25 boss side surfaces of front cover, and can radially slide in hole, When sliding block 4 is located at the major diameter annulus top of shell 15, the big rounding and big ball of the hollow cylinder inner ring of sliding block 4 are tangent, and will Big top dome blocks pin 22, it is prevented to be axially moveable in the groove of 22 centre of pin;When sliding block 4 is located at the major diameter circle of shell 15 When in the middle part of ring, big ball is contacted with the annulus on 4 top of sliding block, and tangent with pin or do not contact, and does not have effect of contraction to pin.
Driving mechanism is made of driving spring 11, spring cup 12, pin 22, washer 13 and nut 21.The one of driving spring 12 End and 15 partition path annulus side contacts of shell, the other end is in spring cup 12;The threaded post of pin 22 is sealed across spring cup 12 The hole at place and washer 12 and nut 21 are fixed.Spring cup 12 can slide axially in the path annulus inner cavity of shell 15.
Buffer gear is made of buffer spring 11, buffering shell 16, buffer cover 20 and rear cover 19.On 19 outside boss of rear cover Through-hole on the downside of the path annulus of counter sink and shell 15 at boss cooperates, by soket head cap screw 14 by rear cover 19 and shell 15 It is connected;The counter sink of step cooperates below threaded hole and buffering 16 cylinder of shell in the outer lateral deviation of rear cover 19, passes through soket head cap screw 18 connect buffering shell 16 with rear cover 19.Buffer cover 20 be installed on buffering shell 16 inside, one side with buffering shell 16 inside Step contact, another side are contacted with buffer spring 17.Be installed below buffer spring 17 in the groove of the top of rear cover 19, top with Buffer cover 20 contacts.
Before pin removal movement, driving spring 11 is in compressive state, has effect always to pin 22, and sells intermediate groove There is big ball 5 to block and cannot move, be applied on big ball 5 in this way, spring force just passes through pin 22, is now in 15 major diameter of shell circle The power that the sliding block 4 on ring top is passed over by big ball 5, and the power is passed to the bead 2 for blocking sliding block, bead 2 and driving 1 inner ring of block is in contact and immovable, allows for pin removal in this way and is in locking state.
It when movement, is heated to memory alloy wire 23, shrinks it and drive block 1 is driven to rotate, when drive block 1 turns to centainly When angle, bead 2 is jumped into the half slot on drive block 1, releases the constraint of sliding block 4 in the axial direction, work of the sliding block 4 in big ball 5 In the middle part of the major diameter annulus of lower slider to shell 15, big ball 5 radially slides under the action of pin 22, until releasing the pact to pin 22 Beam, final pin 22, to moving inside whole device, complete unlock under the action of driving spring 11.
When needing to reuse the device, only bullet need to will be driven using external force by rear cover 19 and the centre bore of buffer cover 20 Spring 11 compress, when being compressed to initial position, plane spring drive drive block rotate and push bead 2 move, bead 2 by with The rounded contact of sliding block 4 pushes 4 to be axially moveable, and sliding block 4 pushes big ball 5 to block pin 22 again, drives after decontroling external force in this way Spring 11 is in compressive state.
