Abstract
The utility model discloses an unlocking device for an explosive bolt. The unlocking device comprises a detonator, a detonating cable, common explosive bolts, precision explosive bolts, a fixing part (a projectile body), a separating part (a booster) and a countersunk bolt. Six paths of explosive bolts are disposed between the fixing part and the separating part, the upper and lower paths of the explosive bolts are the precision explosive bolts, and the other four paths of the explosive bolts are the common explosive bolts. Two concentric cylinders on the rear portion of each precision explosive bolt are precision positioning pins, during mounting of the precision explosive bolt, the first cylinder is in precision fit with the positioning hole in the fixing part, the second cylinder is in precision fit with the positioning hole in the separating part. During mounting of the common explosive bolts, the two cylinders on the rear portion of the common explosive bolts are in non-precision fit with the bolt holes in the fixing part and the separating part. The unlocking device has the advantages that reliable connection before stage separation is guaranteed, the positioning precision problem of the fixing part and the separating part is solved, and reliability of unlocking and separation is increased.
Description
Technical field
The utility model relate to that a kind of guided missile inter-stage divides from blasting bolt tripper.
Background technology
Blasting bolt is used for multiple spot and connects parting surface, blasting bolt likeness in form plain bolt, different is that explosive and initiator are equipped with in inside, when separated, explosive is detonated, bolt disconnects realizes separation, is the critical component of carrier rocket and Booster separation device, plays inter-stage and connects two important function separated with release.General missile airframe and boost motor adopt series system, carrying out, body is higher to connecting positioning requirements while being connected with boost motor, conventionally in the situation that inter-stage connection required precision is higher, need alignment pin location, but the difficulty while adopting in the case alignment pin that increase is separated.
Utility model content
The defect existing for overcoming prior art, the utility model provides a kind of blasting bolt tripper with precision, this blasting bolt tripper, and can guarantee has the higher precision that is connected between body and boost motor, before separated, play connection function, when separated, play release release action.
This blasting bolt tripper comprises initiator, lead quick-fried cable, common blasting bolt, precision blasting bolt, fixture (body), separation member (boost motor) and dormant bolt, the lead-out wire of blasting bolt is all connected to initiator by leading quick-fried cable, described initiator is arranged on fixture, it is characterized in that: described blasting bolt tripper is provided with six road blasting bolts between fixture and separation member, wherein upper and lower two tunnels are precision blasting bolt, all the other four tunnels are common blasting bolt, described precision blasting bolt is anterior the same with common blasting bolt, the concentric Cylinder in two, rear portion is the alignment pin with precision, on described fixture and separation member, the hole of installation accuracy blasting bolt is all the locating hole with precision, described precision blasting bolt is all connected by dormant bolt with fixture with common blasting bolt, during connection, on first Cylinder of precision blasting bolt rear portion and fixture, locating hole is done precision cooperation, first Cylinder of common blasting bolt rear portion and fixture upper bolt hole are done non-precision loose fit, described separation member docks location by precision blasting bolt and common blasting bolt with fixture, during docking location, on second, precision blasting bolt rear portion Cylinder and separation member, locating hole is done precision cooperation, second, common blasting bolt rear portion Cylinder and separation member upper bolt hole are done non-precision loose fit, dock the nut that after having good positioning, described separation member carries by blasting bolt, spring pad is tightened and is fixed on fixture.When separated, initiator is connected, and the explosive in blasting bolt is detonated, and blasting bolt disconnects realizes the separated of separation member and fixture.
This tripper not only guarantees to connect reliable before stage separation, also solved the positioning precision problem of fixture and separation member, increased reliability when release is separated, owing to having loosened the installation accuracy matching problem of all the other common blasting bolts, guarantee that all the other common blasting bolt fitting operations are simple, convenient simultaneously.
