Description

Technical Field

[0001] The present invention belongs to the technical field of unlocking and separating, and in particular relates to a linkage type locking and releasing device capable of adapting to thermal deformation of a bomb wing. Background Art

[0002] Locking and separation technology is widely used in the aerospace field. It plays a vital role in the design and launch of aerospace vehicles. Locking technology is the key technology to ensure that the vehicle remains stable during launch and flight. Common locking technologies include: mechanical locking, memory alloy locking, and electromagnetic locking. Separation technology is the key technology to ensure the reliable separation of the active end and the passive end. The main technologies include: explosive bolt separation, explosive rope separation, and point connection unlocking device.

[0003] Aerospace products require a locking and releasing device to resist mechanical environmental impact and unlock in space, such as the separation of launch vehicles and payloads, the coordinated deployment of large solar panels and other accessories on satellites, etc. At present, most locking and releasing devices in aerospace are pyrotechnic devices, but pyrotechnic devices have problems such as large impact, difficulty in verifying reliability, single use, and pollution. With the exploration and research of the space field, higher requirements are put forward for the reliability, safety, synchronization and separation impact of the connection and separation devices, so there is an urgent need for new connection and separation devices.

[0004] As an important substitute for pyrotechnic devices, the mechanical locking and releasing mechanism currently uses electromagnetic and shape memory alloy wire as the driving source for unlocking. It has the advantages of small impact, recyclability, low pollution, short unlocking time, and verifiable reliability, which can fully make up for the shortcomings of pyrotechnic devices when in use. As a new type of unlocking and releasing device, the mechanical locking and releasing device mainly has the advantages of repeatability, small impact, and low energy consumption, but it also has major disadvantages:

[0005] 1) Most of the unlocking structures of electromagnetic drive sources are complex and their reliability is difficult to guarantee;

[0006] 2) The magnetic field generated by the electromagnetic driving source has a great impact on the space environment and its application scope is limited;

[0007] 3) It is difficult to ensure the synchronization of multiple single-point unlocking devices; Summary of the invention

[0008] In view of this, in order to solve the technical problems existing in the mechanical locking and releasing mechanism mentioned in the above background technology, the present invention proposes a linkage locking and releasing device that can adapt to the thermal deformation of the bomb wing.

[0009] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a linkage locking and releasing device that can adapt to the thermal deformation of the bomb wing, comprising a centralized pressing and releasing mechanism, a linkage locking and releasing mechanism, a driving mechanism and a main linkage rope; one end of the main linkage rope is connected to the centralized pressing and releasing mechanism by using a crimping terminal, and the other end is connected to the driving mechanism, the linkage locking and releasing mechanism comprises a plurality of single-point locking and releasing mechanisms connected in series, and each single-point locking and releasing mechanism is respectively pressed with the main linkage rope through a secondary linkage rope;

[0010] When unlocking is required, the centralized compression release mechanism is unlocked to release the crimped main linkage rope, and the main linkage rope moves under the action of the driving mechanism, driving the secondary linkage rope of the linkage locking release mechanism during the movement, thereby completing the unlocking of the linkage locking release mechanism.

[0011] Furthermore, the centralized compression release mechanism for pyrotechnic unlocking includes a pyrotechnic cutter, a loading nut, a ball pad, a pressure block, an auxiliary seat, a mounting seat and a cutting rod, an auxiliary seat being fixed on the mounting seat, and the thin loading end of the cutting rod passes through the mounting seat, the cutting hole cavity of the pyrotechnic cutter and the auxiliary seat in sequence, and then passes through the pressure block, the ball pad and the loading nut in sequence.

[0012] Furthermore, the centralized compression and release mechanism for pyrotechnic unlocking also includes a capture cap, a pin, a pin, a ball head and a spring. Two pins are screwed into the upper end of the auxiliary seat, and the spring is sleeved outside the pin. The ball head and the pin are connected by threads. The ball head is accommodated in a cavity at the interface between the auxiliary seat and the pressure block. A slope is provided in the cavity to facilitate the rapid removal of the ball head when unlocking. After loading is completed, the capture cap is installed on the auxiliary seat using screws.

[0013] Furthermore, when the centralized compression release mechanism is locked, the cutting rod is fixed to the fixed end through a thread, and the loading nut, ball pad, pressure block, and auxiliary seat constitute a constraint system. Under the action of the constraint system, the spring is compressed, and the pressure block and the auxiliary seat form a complete cavity structure, so that the ball head connected by the pin is accommodated in the cavity of the pressure block and the auxiliary seat, and the locking function is realized by loading the loading nut.

[0014] Furthermore, when the centralized clamping and releasing mechanism is unlocked, an electrical signal is sent out, the pyrotechnic cutter works, the cutting rod is disconnected, the active end and the passive end are released, and at the same time, the loading nut, the ball pad, and the pressure block are separated from the auxiliary seat under the joint action of the preload force and the spring.

After being wound to the end, the coil spring The circular ring structure is hooked on the optical axis end of the pin shaft. Under the action of the compression spring, the pin shaft is prevented from being triggered accidentally. The threaded end of the movable rod passes through the top circular hole of the support seat, the slider and the gasket pass through the movable rod in turn, and the No. 2 loading nut is screwed into the thread of the movable rod. The secondary linkage rope passes through the circular hole of the hanging pin and is crimped. The hanging pin is tightened with the pin shaft through the thread.

The support seat is fixed to the locking structure with screws, and the fixing nut is screwed into the fixing rod. The fixing rod passes through the locking end to connect with the fixed end, and is tightened with the fixing nut to complete the locking connection.

[0016] Furthermore, when the linked locking release mechanism is locked, one end of the coil spring is fixed to the movable rod by a fixing pin, and the other end is hung on the pin shaft by a winding hook, so that the fixed rod and the movable rod are assembled into a complete cylindrical structure, and the movable rod is passed through the round hole on the top of the support seat, and the slider and the ball pad are stacked in sequence, and the No. 2 loading nut is screwed into the screw rod, the fixed rod is connected to the fixed end, and fastened with the fixing nut, and the No. 2 loading nut is loaded using a loading tool to complete the compression connection between the fixed end and the locking end.

[0017] Furthermore, when the linkage locking release mechanism is unlocked, the secondary linkage rope is pulled to drive the hanging pin and the pin shaft to slide radially, thereby releasing the directional constraints on the coil spring. The coil spring rotates around the movable rod and the fixed rod under the action of its own restoring force and is released. At the same time, the movable rod and the fixed rod are decomposed under the interaction force of the contact surface of the screw thread, thereby completing the unlocking and separation of the active end and the passive end.

[0018] Furthermore, when the linkage locking and releasing device that can adapt to thermal deformation of the wing is in a locked state, the cutting rod is installed at the fixed end, and a constraint system is formed by a No. 1 loading nut, a ball pad, a pressure block and an auxiliary seat, and the ball head connected by the pin is accommodated in the cavity of the pressure block and the auxiliary seat, and the No. 1 loading nut is used to load and complete the compression connection of the concentrated compression point, and the fixed rod in the linkage locking and releasing mechanism is installed to the fixed end, and a constraint system is formed by a fixed pin, a coil spring and a pin shaft, and the fixed rod and the movable rod are assembled to complete the cylindrical structure, and the support seat is connected to the fixed end and passes through the movable rod, and the slider, the ball pad and the No. 2 loading nut are successively inserted from the top of the movable rod and a torque is applied to complete the connection of the locking point, and one end of the main linkage rope is connected to the pin of the concentrated compression and releasing mechanism, and the other end of the main linkage rope is connected to the driving mechanism, and the secondary linkage rope in the linkage locking and releasing mechanism distributed in the middle of the main linkage rope is connected to the main linkage rope by crimping to complete the locking connection of the whole set of linkage locking and releasing device.

[0019] Furthermore, when the linkage locking release device that can adapt to thermal deformation of the wing is in the unlocked state, an electrical signal is sent, the pyrotechnic cutter works, the cutting rod is broken, and the fixed end and the passive end of the concentrated compression point are unlocked and separated. At the same time, under the action of the spring, the No. 1 loading nut, the ball pad, and the pressure block move axially, and the pin and the ball head are quickly separated from the cavity of the pressure block and the auxiliary seat under the action of the driving mechanism, driving the secondary linkage rope in the linkage locking mechanism to move, and the secondary linkage rope pulls the hanging pin and the pin shaft to slide, and the end of the pin shaft releases the constraint on the coil spring, and the coil spring starts to rotate under the action of the restoring force, and at the same time releases the tightening constraint on the movable rod and the fixed rod, and the movable rod and the fixed rod are separated under the action of the screw contact surface, completing the unlocking and separation of the locking point.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0033] See also Figure 1-5 To describe this embodiment, a linkage type locking and releasing device that can adapt to the thermal deformation of the bomb wing includes a centralized compression and releasing mechanism 1, a linkage locking and releasing mechanism, a driving mechanism 3 and a main linkage rope 4;

[0034] Locking state: one end of the main linkage rope 4 is connected to the centralized clamping and releasing mechanism 1 by using a crimping terminal, and the other end is connected to the driving mechanism 3. The linkage locking and releasing mechanism includes multiple single-point locking and releasing mechanisms 2 connected in series, and each single-point locking and releasing mechanism 2 is respectively clamped with the main linkage rope 4 through the secondary linkage ropes 2-12.

[0035] Unlocked state: the centralized compression release mechanism 1 is unlocked, and the crimped main linkage rope 4 is released. The main linkage rope 4 starts to move along a specific direction under the action of the driving mechanism 1. During the movement, it drives the auxiliary linkage ropes 2-12 of multiple series-connected single-point locking and releasing mechanisms 2, thereby completing the unlocking of the linkage locking and releasing mechanism.

[0036] The centralized compression release mechanism 1 for pyrotechnic unlocking mainly comprises a pyrotechnic cutter 1-1, a capture cap 1-2, a No. 1 loading nut 1-3, a pin 1-4, a ball pad 1-5, a pressure block 1-6, a pin 1-7, a ball head 1-8, an auxiliary seat 1-9, a mounting seat 1-10, a fixing screw 1-11, a cutting rod 1-12 and a spring 1-13. The mounting seat 1-10, the auxiliary seat 1-9, the pressure block 1-6, the ball head 1-8, the ball pad 1-5, the No. 1 loading nut 1-3 and the cutting rod 1-12 are load-bearing structural parts, which are connected in sequence from bottom to top to form a complete load-bearing structure.

[0037] The cutting part of the pyrotechnic cutter 1-1 passes through the horizontal circular hole of the auxiliary seat 1-9, and the two are fixed to the mounting seat 1-10 at the same time with fixing screws. Two pins 1-4 are screwed into the upper end of the auxiliary seat 1-9, and the compression springs 1-13 are respectively inserted into the outside of the pins 1-4. The thin loading end of the cutting rod 1-12 passes through the through hole of the mounting seat, the hole cavity of the cutting part of the pyrotechnic cutter, and the vertical circular hole of the auxiliary seat from the bottom of the mounting seat 1-10, and then the pressure block 1-6, the ball pad 1-5, and the No. 1 loading nut 1-3 are successively inserted into the cutting rod 1-12, and the No. 1 loading nut 1-3 is screwed into the thin loading end of the cutting rod 1-12. The No. 1 loading nut 1-3 is rotated using a loading tool. Under the action of the nut squeezing, the ball pad 1-5 and the pressure block 1-6 move axially along the cutting rod 1-12, and the movement of the pressure block 1-6 causes the compression spring outside the pin 1-4 to be accommodated in the cavity of the pressure block 1-6 and the auxiliary seat 1-9. The ball head 1-8 is connected to the pin 1-7 by a thread, and the ball head 1-8 is accommodated in a cavity between the auxiliary seat 1-9 and the pressure block 1-6. The cavity is provided with an inclined surface to facilitate the rapid release of the ball head when unlocking. After loading is completed, the capture cap 1-2 is installed on the auxiliary seat 1-9 using screws.

[0038] When the centralized clamping and releasing mechanism 1 is locked, the cutting rod 1-12 is fixed to the fixed end through a thread, and the No. 1 loading nut 1-3, the ball pad 1-5, the pressure block 1-6, and the auxiliary seat 1-9 constitute a constraint system. Under the action of the constraint system, the spring 1-13 is compressed, and the pressure block 1-6 and the auxiliary seat 1-9 form a complete cavity structure, so that the ball head 1-8 connected by the pin 1-7 is accommodated in the cavity of the pressure block and the auxiliary seat 1-9, and the locking function is realized by loading the No. 1 loading nut 1-3.

[0039] When the centralized clamping release mechanism 1 is unlocked, an electrical signal is sent out, the pyrotechnic cutter 1-1 works, the cutting rod 1-12 is disconnected, and the active end and the passive end are released. At the same time, the No. 1 loading nut 1-3, the ball pad 1-5, and the pressure block 1-6 are separated from the auxiliary seat 1-9 under the joint action of the preload force and the spring 1-13. At the same time, the ball head 1-8 connected to the pin 1-7 can be removed from the cavity of the pressure block 1-6 and the auxiliary seat 1-9 under the action of external force, completing the unlocking and release of the centralized point.

[0040] The technical scheme of the linkage locking release mechanism is as follows: the single-point locking release mechanism 2 mainly includes a fixed rod 2-1, a movable rod 2-2, a coil spring 2-3, a screw plug 2-4, a pin 2-5, a compression spring 2-6, a slider 2-7, a second loading nut 2-8, a gasket 2-9, a support seat 2-10, a reversing block 2-11, a secondary linkage rope 2-12, a hanging pin 2-13, a fixed pin 2-14, and a fixed nut 2-15. The compression spring 2-6 and the screw plug 2-4 are sequentially inserted into the pin 2-5, the optical axis end of the pin 2-5 is inserted into the threaded through hole of the movable rod 2-2, and the screw plug 2-4 is screwed into the movable rod 2-2. The fixed rod 2-1 is passed through the small ring at the end of the coil spring 2-3 and fixed through the threaded hole of the movable rod 2-2. The fixed rod 2-1 and the movable rod 2-2 are spliced ​​by screw threads, and the coil spring 2-3 is driven by the tooling to be wound around the fixed rod 2-1 and the movable rod 2-2. After winding to the end, the small ring structure of the coil spring 2-3 is hooked on the optical axis end of the pin shaft 2-5. Under the action of the compression spring 2-6, the pin shaft 2-5 is prevented from being accidentally triggered and causing mislocking, so that the fixed rod 2-1 and the movable rod 2-2 form a complete cylindrical load-bearing structure.

[0041] The threaded end of the movable rod 2-2 passes through the top circular hole of the support seat 2-10, the slider 2-7 and the gasket 2-9 pass through the movable rod 2-2 in sequence, and the No. 2 loading nut 2-8 is screwed into the thread of the movable rod 2-2. The arc-shaped slider 2-7 can advantageously adapt to the thermal deformation of the structure under heating conditions. The secondary linkage rope 2-12 passes through the circular hole of the hanging pin 2-13 and is crimped, and the hanging pin 2-13 is screwed together with the pin shaft 2-5 through a thread. The reversing block 2-11 is fixed to the side of the support seat 2-10 by screws, and the fixed surface is oriented in the same direction as the hanging pin 2-13. The support seat 2-10 is fixed to the locking structure with screws, and the fixing nut 2-15 is screwed into the fixed rod 2-1. The fixed rod 2-1 passes through the locking end to connect with the fixed end, and is tightened with the fixing nut 2-15 to complete the locking connection.

[0042] The locking state of the linkage locking release mechanism: one end of the coil spring 2-3 is fixed to the movable rod 2-2 through the fixed pin 2-14, and the other end is hung on the pin shaft 2-5 through the winding hook. The fixed rod 2-1 and the movable rod 2-2 are assembled into a complete cylindrical structure. The movable rod 2-2 passes through the round hole on the top of the support seat 2-10, and the slider 2-7 and the gasket 2-9 are stacked in sequence, and the second loading nut 2-8 is screwed into the screw. The fixed rod 2-1 is connected to the fixed end and tightened with the fixed nut 2-15. The second loading nut 2-8 is loaded using the loading tool to complete the compression connection between the fixed end and the locking end.

[0043] Unlocking state of linkage locking release mechanism: pull the secondary linkage rope 2-12, drive the hanging pin 2-13 and the pin shaft 2-5 to slide radially, release the constraints on the coil spring 2-3 in all directions, and the coil spring 2-3 rotates around the movable rod 2-2 and the fixed rod 2-1 under the action of its own restoring force to release. At the same time, the movable rod 2-2 and the fixed rod 2-1 are decomposed under the interaction force of the contact surface of the thread teeth, completing the unlocking and separation of the active end and the passive end.

[0044] The overall locking state of the linkage locking and releasing device that can adapt to the thermal deformation of the wing described in the present invention; the cutting rod 1-12 is installed at the fixed end, and a constraint system is formed by the No. 1 loading nut 1-3, the ball pad 1-5, the pressure block 1-6, and the auxiliary seat 1-9. The ball head 1-8 connected with the pin 1-7 is accommodated in the cavity of the pressure block 1-6 and the auxiliary seat 1-9, and the No. 1 loading nut 1-3 is used to load and complete the compression connection of the concentrated compression point. The fixed rod 2-1 in the linkage locking and releasing mechanism is installed to the fixed end, and a constraint system is formed by the fixed pin 2-14, the coil spring 2-3, and the pin shaft 2-5. The fixed rod 2-1 and the movable rod 2-2 are assembled to complete the cylindrical structure. The support seat 2-10 is connected to the fixed end and passes through the movable rod 2-2. The slider 2-7, the ball pad 2-9, and the No. 2 loading nut 2-8 are successively inserted from the top of the movable rod 2-2, and a torque is applied to complete the connection of the locking point. One end of the main linkage rope 4 is connected to the pin 1-7 of the centralized compression release mechanism 1, and the other end of the main linkage rope 4 is connected to the driving mechanism 3. The auxiliary linkage rope 2-12 in the linkage locking release mechanism 2 distributed in the middle of the main linkage rope 4 is connected to the main linkage rope 4 by crimping, completing the locking connection of the entire linkage locking release device.

[0045] The overall unlocking process of the linkage locking release device that can adapt to the thermal deformation of the bomb wing described in the present invention is as follows: the electrical signal is sent, the pyrotechnic cutter 1-1 works, the cutting rod 1-12 is broken, and the fixed end and the passive end of the concentrated pressing point are unlocked and separated. At the same time, under the action of the spring 1-13, the No. 1 loading nut 1-3, the ball pad 1-5, and the pressure block 1-6 move axially. Under the action of the driving mechanism, the pin 1-7 and the ball head 1-8 quickly disengage from the cavity of the pressure block 1-6 and the auxiliary seat 1-9, driving the secondary linkage rope 2-12 in the linkage locking mechanism to move. The secondary linkage rope 2-12 pulls the hanging pin 2-13 and the pin shaft 2-5 to slide. The end of the pin shaft 2-5 releases the constraint on the coil spring 2-3. The coil spring 2-3 starts to rotate under the action of the restoring force, and at the same time releases the tightening constraint on the movable rod 2-2 and the fixed rod 2-1. The movable rod 2-2 and the fixed rod 2-1 are separated under the action of the screw thread contact surface, completing the unlocking and separation of the locking point.

The embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. According to the content of this specification, many modifications and changes can be made.
