Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of inertial navigation device installation, in particular to a ring type locking and releasing device for gyroscopic directional instrument. BACKGROUND

[0002] In the transportation, adjustment and calibration process of the gyroscopic sensitive part, the locking and releasing mechanism is needed to realize the locking and releasing operation, so as to fix the position of the sensitive part in the non-working state, and realize reliable release before and after the working state. The locking and releasing process is not only the implementation of geometric constraint, but also directly affects the attitude keeping of the sensitive part after locking and the position consistency in subsequent repeated installation.

[0003] The existing design adopts the "upper supporting type" clamping mode, that is, a supporting surface or supporting point is arranged below the sensitive part, and a lateral limiting or clamping part is used to realize fixation. The stress path of this type of structure is mainly below the supporting surface, and the lateral part only plays a local limiting or pre-tightening role, and it is difficult to form a symmetrical radial force field that is concentrated and directed to the center of the shell. In this mechanical environment, the tangential component and biasing moment are easily superimposed during clamping, and the differences in part tolerance and friction conditions make the sensitive part prone to slight attitude deviation after locking. The accumulation of this deviation will cause errors in coaxiality and affect the consistency of repeated positioning, thereby adversely affecting the subsequent calibration and measurement accuracy.

[0004] Therefore, the key problem to be solved at present is how to establish a clamping force field that is mainly radial and symmetrically distributed along the circumferential direction during locking and releasing, so that the positioning of the sensitive part after locking is more stable, thereby reducing the coaxiality deviation and maintaining high position consistency in repeated clamping. Design and improvement for this problem are of great significance to improve the installation reliability and measurement stability of the gyroscopic sensitive part in practical application. SUMMARY

[0024] Please refer to Figures 1-7 , Figure 1 The overall structure schematic diagram of the embracing type lock release device of the gyroscopic directional instrument provided by an embodiment of the present application is shown in the figure. Figure 2For Figure 1 The structural schematic diagram of the lock release shell of the device shown in the figure; Figure 3 For the cooperation schematic diagram of the locking mechanism and the radial driving mechanism in an embodiment of the present application; Figure 4 The connection schematic diagram of the lifting wedge provided by an embodiment of the present application on the transmission rod; Figure 5 The structural schematic diagram of the lifting wedge provided by an embodiment of the present application; Figure 6 The structural schematic diagram of the locking seat provided by an embodiment of the present application; Figure 7 The installation schematic diagram of the locking block in the locking seat provided by an embodiment of the present application. As Figures 1-7 The present application provides a ring-type lock release device of a gyroscopic directional instrument, which comprises a lock release shell 100, three sets of locking mechanisms 200, three sets of radial driving mechanisms 300 and three sets of needle-type conductive connectors 400.

[0025] The lock release shell 100 is a hollow cylindrical structure, and the three sets of locking mechanisms 200 are uniformly arranged in the circumferential direction of the lock release shell 100, which are used to implement symmetrical ring-type clamping on the sensitive part of the gyro in the locked state. The locking mechanism 200 and the radial driving mechanism 300 are arranged one by one, each set of radial driving mechanism 300 is in transmission connection with a corresponding set of locking mechanism 200, each set of locking mechanism 200 comprises a locking seat 210, a locking block 220 and two compression springs 230, the locking seat 210 is connected with the output end of the radial driving mechanism 300 and can move in the radial direction of the lock release shell 100 under the driving of the radial driving mechanism 300; the locking block 220 is installed on the locking seat 210 and connected with the locking seat 210 through the two compression springs 230, the locking block 220 can move synchronously when the locking seat 210 moves radially to synchronously clamp or release the sensitive part of the gyro under the driving of the locking seat 210; one set of needle-type conductive connectors 400 is arranged on each of the three locking blocks 220, the needle-type conductive connectors 400 can be in contact with the conductive contact block on the outer periphery of the sensitive part of the gyro to form an electrical connection when the locking block 220 radially clamps the sensitive part of the gyro.

[0026] In the embodiment, the lock release housing 100 is a hollow cylindrical structure, three sets of locking mechanisms 200 are uniformly arranged along the circumferential direction and are respectively connected with corresponding radial driving mechanisms 300 to realize the linear advance and retreat of the locking seats 210 in the radial direction of the housing. Thus, the three locking blocks 220 are driven by the radial driving mechanisms to load the sensitive part of the gyroscope in the radial direction. Since the three are arranged at equal angles along the circumferential direction, the forces are approximately symmetrically distributed in geometry, and the resultant force tends to the center of the housing. Through this symmetrical force applying mode, the tangential friction or biasing torque generated by the non-radial component on the surface of the sensitive part can be reduced, so that the clamping action remains in the main radial direction. Thus, the positioning of the sensitive part relative to the center of the housing is more stable after clamping, the coaxiality deviation is reduced, and the position consistency during repeated installation is also improved.

[0027] Further, each set of locking mechanisms 200 is composed of a locking seat 210, a locking block 220 and two compression springs 230. The locking seat 210 provides radial guidance and bears displacement input, the locking block 220 is connected with the locking seat 210 through the compression spring 230 to form an elastic coupling relationship. During the clamping action, the compression spring 230 enables the locking block 220 to have certain compliance, so that when there is a slight deviation in assembly or manufacturing, the compression spring 230 can absorb part of the displacement difference, thereby avoiding local overload caused by rigid contact. Further, when the three locking blocks 220 contact the surface of the sensitive part at different time points, the compression spring 230 can automatically adjust the force inside the structure, so that the clamping force of each locking point tends to be balanced, reducing the situation of excessive force on a single point. In this way, the stress concentration on the surface of the sensitive part of the gyroscope caused by clamping is relieved, and the impact during the instantaneous clamping process is also reduced. Through this structural arrangement, the overall clamping and releasing process is more stable, and the motion repeatability and rationality of force distribution are improved.

[0028] In addition, a needle type conductive connector 400 is installed on each of the three locking blocks 220, and when the clamping action is completed, the conductive connector 400 directly contacts the conductive contact block on the outer periphery of the sensitive part of the gyroscope to establish the required electrical path. Since the needle type conductive connector 400 and the locking block 220 are in the same loading direction, the contact pressure and the clamping force are generated by the same mechanism, so they can better coordinate in the force direction and action timing. This arrangement not only avoids additional independent plugging operation, but also simplifies the electrical connection implementation path. At the same time, the electrical contact point is in a stable compression state during the entire clamping and holding stage, the contact resistance fluctuation can be suppressed, and the relative micro-motion of the contact surface is also reduced. Thus, the mechanical clamping and electrical connection are synchronized and coordinated in the spatial arrangement and action timing, which not only reduces the additional wiring link, but also makes the electrical connection more reliable and the maintenance operation more convenient.

[0029] In some embodiments, the radial driving mechanism 300 is mounted on the lock release housing 100, and the radial driving mechanism 300 comprises a lock release motor 310, a spur gear transmission pair 320 connected with the output end of the lock release motor 310, a transmission rod 330 connected with the spur gear transmission pair 320, and a lifting wedge 340 threadedly connected with the transmission rod 330.

[0030] In the present embodiment, the lock release motor 310 is mounted in the shell wall of the lock release housing 100, and the output end of the lock release motor 310 is arranged upwardly and connected with the spur gear transmission pair 320. A sliding hole 101 is formed in the shell wall of the lock release housing 100, through which the locking mechanism 200 is arranged and can move radially. The upper end of the transmission rod 330 is connected with the spur gear transmission pair 320, and the lower end of the transmission rod 330 extends vertically into the shell wall of the lock release housing 100 and is connected with the locking mechanism 200 at the sliding hole 101. The transmission rod 330 can rotate clockwise and counterclockwise under the driving of the lock release motor 310 to make the locking mechanism 200 move radially.

[0031] In the present embodiment, the lock release motor 310 is mounted in the shell wall of the lock release housing 100, and the output end of the lock release motor 310 is arranged upwardly and connected with the spur gear transmission pair 320. A sliding hole 101 is formed in the shell wall of the lock release housing 100, through which the locking mechanism 200 is arranged and can move radially. The upper end of the transmission rod 330 is connected with the spur gear transmission pair 320, and the lower end of the transmission rod 330 extends vertically into the shell wall of the lock release housing 100 and is connected with the locking mechanism 200 at the sliding hole 101. The transmission rod 330 can rotate clockwise and counterclockwise under the driving of the lock release motor 310 to make the locking mechanism 200 move radially.

[0032] Further, the lifting wedge 340 is threadedly connected with the transmission rod 330. The forward and reverse output of the lock release motor 310 can be converted into clockwise or counterclockwise rotation of the transmission rod, and the rotation can be converted into axial displacement through the threaded pair, and the displacement accuracy is limited by the pitch parameter. With this structure, the displacement amount during radial driving can be decomposed into continuous and measurable steps, so that the locking mechanism 200 has good controllability during the advancing and retreating process.

[0033] At the same time, the driving components are arranged concentratedly on the lock release housing 100, and the lock release housing 100 can weaken the direct influence of the external environment. The sliding hole 101 is only used as a guide channel for the locking mechanism 200, and its opening position determines the arrangement position and maintenance path of the locking mechanism 200, avoiding the exposure of the driving components in a large area. This structural arrangement helps to reduce the possibility of foreign matter entering or wear intensifying, so that the device is more likely to maintain a stable working state in actual use.

[0034] In some embodiments, the lock release motor 310 is a servo motor, the lock seat 210 is provided with a connecting hole 211 matched with a lifting wedge 340, the lifting wedge 340 is threadedly connected to the lower end of the transmission rod 330 and located in the connecting hole 211, and a guide slope 2111 capable of preventing the lifting wedge 340 from rotating in the connecting hole 211 and guiding the lifting wedge 340 to axially ascend and descend on the transmission rod 330 is formed in the connecting hole 211; the lifting wedge 340 is a parallelogram structure with an internally threaded connecting hole, the outer surface of the lifting wedge 340 has opposite parallel slopes matched with the connecting hole 211, when the transmission rod 330 rotates, the lifting wedge 340 can axially ascend and descend in the connecting hole 211 without rotating, and can form a wedge-shaped transmission with the guide slope 2111 to extrude and push the lock seat 210 to move in the radial direction relative to the lock release housing 100, thereby driving the lock block 220 to realize radial clamping and release.

[0035] In the above embodiments, a servo motor is used as the driving source, which can provide reliable output power for the rotation of the transmission rod 330. The rotation is refined into axial displacement determined by the pitch parameter through the threaded pair cooperation of the transmission rod 330 and the lifting wedge 340, and then converted into radial advancement of the lock seat 210 through the cooperation of the lifting wedge 340 in the connecting hole 211. At the same time, the guide slope 2111 of the connecting hole 211 and the parallel slope of the outer surface of the lifting wedge 340 form a face-to-face cooperation relationship, which can limit the rotation of the lifting wedge 340 in the connecting hole 211 and only allow it to axially ascend and descend, thereby avoiding the torque directly acting on the lock seat 210 and reducing the lateral disturbance; on the other hand, the wedge-shaped cooperation guides the axial input of the transmission rod to the radial force of the housing under geometric constraints, reducing the interference of the tangential component, so that the locking process is more stable.

[0036] In addition, the lifting wedge 340 is designed as a parallelogram structure with an internal thread, and its parallel slope is in contact with the connecting hole 211, which can provide a stable contact surface and a constant wedge angle during force application. Through this geometric relationship, the rotation angle of the transmission rod 330 is first converted into the axial displacement of the lifting wedge 340 through the threaded pair, and then further converted into the radial feed amount of the lock seat 210 under the wedge-shaped guide action. Therefore, a clear corresponding relationship is formed between the driving input and the radial feed, so that the same input angle can produce consistent displacement and clamping force.

[0037] In some embodiments, the spur gear pair 320 includes a driving gear arranged on the output shaft of the lock release motor 310, a driven gear arranged on the transmission rod 330, and a transition gear between the driving gear and the driven gear to achieve torque transmission. The transition gear is engaged with the driving gear and the driven gear, respectively. In actual installation, the transition gear can be installed in cooperation with the bearing on the gear shaft connected with the transition gear, and the transmission rod 330 can be installed in cooperation with the bearing on the transmission rod 330.

[0038] In the present embodiment, the spur gear pair 320 introduces a three-stage transmission arrangement of driving gear, transition gear and driven gear, making the power transmission path and installation layout more reasonable. First, the transition gear is arranged between the driving gear and the driven gear, which is equivalent to adding an adjustable engagement point between the output shaft of the lock release motor 310 and the transmission rod 330. In this way, the center distance of the driving gear and the driven gear does not have to be fixed as the distance between the motor output shaft and the transmission rod, thereby improving the design flexibility and facilitating the arrangement in the limited space of the housing 100.

[0039] Further, the transition gear can change the transmission direction, so that the transmission rod 330 can be arranged more appropriately relative to the axis of the lock release motor 310. This adjustment can make the overall structure more compact and more adaptable in space utilization.

[0040] In addition, the introduction of the transition gear also enables flexible adjustment of the total transmission ratio of the gear pair. In this way, not only can the harsh engagement conditions caused by the limitation of module and tooth number when the driving gear and the driven gear are directly engaged be avoided, but also the engagement force can be reduced by reasonably selecting the gear parameters, thereby improving the stability and reliability in the transmission process. In operation, the torque transmission is smoother, and the output of the radial drive is more stable.

[0041] In summary, by adopting a three-stage gear arrangement in the spur gear pair 320, the present embodiment not only solves the problems of limited space and poor engagement that may be encountered when the lock release motor 310 and the transmission rod 330 are directly arranged, but also brings more flexible installation space, more reliable torque transmission and more smooth radial driving effect.

[0042] In some embodiments, the lock seat 210 is provided with a containing cavity 212 on the inner side for arranging the lock block 220, the lock block 220 is arranged in the containing cavity 212, the lock block 220 is provided with a clamping groove 221 on the inner side for clamping the gyro sensitive part, the lock block 220 is provided with a needle-type conductive connector 400 at the position of the clamping groove 221, and the lock release housing 100 is provided with a groove 102 arranged in a ring shape at the same height as the clamping groove 221 on the inner wall surface. Optionally, the clamping groove 221 is a V-shaped clamping groove, which is convenient for tightly fitting with the V-shaped boss of the gyro sensitive part to realize clamping.

[0043] Firstly, the present embodiment is capable of arranging the locking block 220 inside the locking seat 210 on the inner side by opening a containing cavity 212 on the inner side of the locking seat 210, the cavity wall of the containing cavity 212 can guide its movement and limit its swing, thereby reducing the swing and friction bias load generated during the radial feeding process. At the same time, the cavity wrapping structure can shield the locking block 220, reducing the possibility of contact with external objects or contamination after exposure, thereby reducing the risk of action obstruction or damage.

[0044] Secondly, the locking block 220 is provided with a clamping groove 221 on the inner side, which directly defines the contact force point position of the gyro sensitive part. In this way, the clamping point is fixed at a uniform height and orientation, the tangential slip is limited, and the contact position during repeated clamping is more consistent. The needle type electric connector 400 is arranged at the position of the clamping groove 221, so that the electric contact point and the mechanical clamping point coincide, the electric connection path is shortened, and the contact state is more stable.

[0045] In addition, the inner wall of the shell 100 is provided with a groove 102 arranged in a ring shape at the same height position of the clamping groove 221, and the groove 102 and the clamping groove area correspond to each other, so that the three sets of locking mechanisms can form a common restriction reference in the ring direction when clamping the gyro sensitive part in the radial direction. Through this same height and ring-shaped continuous arrangement, the three sets of locking mechanisms are constrained in the same reference plane on the circumference, ensuring that the clamping position is in a unified ring surface, thereby helping to realize the symmetrical distribution of three-way clamping force, and further improving the coaxiality and stability of the sensitive part after locking.

[0046] In some embodiments, each set of needle type electric connector 400 includes a pair of left and right spaced apart electric contact needles 410 arranged on the locking block 220 for contacting the electrically conductive contact block of the gyro sensitive part to form an electric connection, and the locking block 220 is provided with two mounting holes 222 for mounting the electric contact needles 410. The electric contact needle 410 is a built-in spring compressible spring contact needle, and the needle tip end of the electric contact needle 410 can be compressed back and apply contact pressure when clamping the electrically conductive contact block of the gyro sensitive part in the radial direction of the locking block 220, to reliably contact the electrically conductive contact block on the outer periphery of the gyro sensitive part to form an electric connection.

[0047] In the embodiment, the stability and adaptability of the electrical connection during clamping are improved by optimizing the arrangement and structure of the needle-type conductive connector 400. A pair of left and right conductive contact needles 410 are arranged on the locking block 220 with a fixed spacing and a uniform axial direction, and the symmetric force can reduce the local torque and contact surface warping caused by single-point contact. When the locking block 220 is radially compressed against the gyro-sensitive part, the needle tips of the contact needles 410 are compressed and partially withdrawn, thereby absorbing the gap caused by assembly deviation, thermal expansion and contraction, and surface micro-undulations by using elastic force, which helps to reduce the risk of overpressure or loose connection, thereby keeping the contact resistance at a relatively stable level.

[0048] In some embodiments, a limiting screw 213 is arranged at the outer lower side of the locking seat 210, which is screwed into the threaded hole at the outer lower side of the locking seat 210 and has a limiting end facing the gyro-sensitive part. Before and during clamping of the gyro-sensitive part, the limiting screw 213 is in a loosened state. After the locking block 220 completes the radial clamping of the gyro-sensitive part, the limiting screw 213 is tightened to make the limiting end cooperate with the limiting part on the gyro-sensitive part, thereby forming additional fixation of the gyro-sensitive part. When the gyro-sensitive part needs to be released, the limiting screw 213 is loosened first to remove the additional fixation before unlocking.

[0049] In the embodiment, the limiting screw 213 is additionally arranged at the outer lower side of the locking seat 210, and is specified to perform the operation sequence of loosening first, tightening second, and loosening third in use, thereby further converting the clamping retention mode from the "encircling clamping" mode to a combined fixation form combining "encircling" and "rigid point cooperation".

[0050] Before and during clamping, the limiting screw 213 remains in a loosened state, which does not affect the symmetric radial feeding of the three sets of locking mechanisms 200, avoiding interference with the clamping force distribution and self-centering process. After the locking block 220 completes the radial clamping, the limiting screw 213 is manually tightened to make the end of the limiting screw 213 form point or surface contact with the limiting part on the gyro-sensitive part, thereby introducing additional rigid constraint on the basis of the original three-way normal clamping. In the case of vibration, impact or long-term loading, this rigid constraint can inhibit micro-sliding and creeping, which helps to further reduce the risk of relaxation. When released, the limiting screw 213 needs to be loosened first, and then the unlocking operation is performed, which can avoid hard friction between the limiting end and the gyro-sensitive part during the unlocking stroke, thereby reducing the risk of surface damage.

[0051] In some embodiments, the lock release housing 100 comprises an upper housing part 110 and a lower housing part 120, which are arranged oppositely and detachably connected; the shell wall of the upper housing part 110 is provided with mounting positions for mounting the lock release motor 310, the spur gear transmission pair 320 and the transmission rod 330, and three slip holes 101 corresponding to the locking mechanisms 200 are uniformly arranged on the lower part of the shell wall of the lock release housing 100.

[0052] In the specific implementation process, the detachable connection mode of the upper housing part 110 and the lower housing part 120 is not limited to a single structure form, and can be selected according to actual use requirements and processing conditions. For example, screw connection, combined connection of bolt and positioning pin, buckle connection, or other conventional mechanical connection modes convenient for disassembly can be used. The above-mentioned modes all belong to the conventional technical means in the art, and can be easily realized by those skilled in the art. The present application does not limit the specific connection structure, as long as the stable fixation and repeated disassembly between the upper housing part 110 and the lower housing part 120 can be realized, which falls within the protection scope of the present application.

[0053] In the above embodiment, the shell wall of the upper housing part 110 is provided with mounting positions for mounting the lock release motor 310, the spur gear transmission pair 320 and the transmission rod 330, which share the same housing, and through this arrangement, the relative positions of the motor shaft of the lock release motor 310, the gear center distance and the transmission rod axis are defined by the same rigid carrier, which can improve the compactness of the device structure. The lower part of the shell wall of the lower housing part 120 is uniformly provided with three slip holes 101, which correspond to three groups of locking mechanisms 200. The three slip holes 101 have uniform circumferential angle and the same height of movement window in geometric position, so that each locking mechanism 200 obtains consistent avoidance and guiding boundary in the radial stroke. In addition, the upper housing part 110 and the lower housing part 120 are detachably connected. The driving components can be pre-installed in the upper housing, and then combined with the lower housing part 120. In this way, during maintenance or replacement, they can be individually disassembled for maintenance.

[0054] In some embodiments, the shell wall of the lock release housing 100 is provided with a stroke detection assembly 500 below each locking mechanism 200, which comprises two micro travel switches 510 arranged in the radial movement direction of the locking seat 210, and the two micro travel switches 510 are respectively used for detecting the locking-in-place state of the locking block 220 when the radial clamping gyro sensitive part is locked and the release-in-place state when the radial release gyro sensitive part is released; the triggering end of the micro travel switch 510 is arranged towards the locking seat 210, and when the locking seat 210 moves to the corresponding position of the locking-in-place or release-in-place under the driving of the radial driving mechanism 300, the corresponding micro travel switch 510 can be triggered to output the corresponding stroke signal.

[0055] In the present embodiment, a stroke detection assembly 500 is arranged on the shell wall of the lock-and-release housing 100 and below each set of locking mechanisms 200. The stroke detection assembly 500 includes two micro-stroke switches 510 arranged along the radial movement direction of the locking seat 210 and spaced apart, corresponding to the “locked-in-place” and “released-in-place” positions respectively, with the triggering end facing the locking seat 210. When the locking seat 210 is moved to the corresponding position under the action of the radial driving mechanism 300, the corresponding micro-stroke switch 510 will be triggered and output a corresponding stroke signal. At the same time, the micro-stroke switch 510 is arranged adjacent to each set of locking mechanisms 200, with the triggering end facing the locking seat 210, for being directly triggered when the locking seat 210 moves in and out along the radial direction. When the locking seat 210 is moved to the position corresponding to the “locked-in-place” or “released-in-place” position under the action of the radial driving mechanism 300, the corresponding micro-stroke switch 510 can be triggered to output a stroke signal representing the state, thereby providing accurate feedback for the control system to clamp or release.

[0056] It should be noted that the micro-stroke switch 510 can be an existing mechanical micro-switch or an optical limit switch, and those skilled in the art can select a suitable model according to the actual installation space and detection accuracy requirements, which is not limited in the present application. In specific implementation, the micro-stroke switch 510 adopts a common mechanical micro-switch, which is triggered by the locking seat 210 through physical contacts to output a switch quantity signal; or an optical stroke switch can be selected according to the installation environment and response speed requirement, to realize non-contact detection and output corresponding electrical signals by blocking or transmitting light beams. Those skilled in the art can make reasonable selection according to factors such as structure arrangement space, service life, anti-interference ability and interface mode.

[0057] In some embodiments, the gyroscopic directional instrument embracing lock-and-release device of the present application further includes a control unit 600 electrically connected with the stroke detection assembly 500 and the needle-type conductive connector 400. The control unit 600 is configured to determine the “locked-in-place” state and the “released-in-place” state of the locking mechanism 200 when receiving the stroke signal output by the micro-stroke switch 510 of the stroke detection assembly 500. When determining that the locking mechanism 200 is in the “locked-in-place” state, the control unit 600 controls the needle-type conductive connector 400 to establish electrical connection with the conductive contact block of the gyroscopic sensitive part after a delay preset time, to realize power supply and signal transmission of the working circuit of the gyroscopic sensitive part. When determining that the locking mechanism 200 is in the “released-in-place” state, the control unit 600 controls to disconnect the electrical connection of the needle-type conductive connector 400, to avoid power consumption and signal interference in the non-working state. The delay preset time is in the range of 0.5 seconds to 3 seconds. Optionally, the delay preset time is 2 seconds.

[0058] In this embodiment, the control unit 600 is added to the gyroscopic directional instrument ring type locking device, and the electric connection delay mechanism based on the travel signal determination is logically introduced. The control unit 600 collects the travel signal of the micro travel switch 510 in real time, and when the locking mechanism 200 reaches the clear state of "locking to position" or "lowering to position", a more reliable determination can be made to avoid false triggering caused by being in the intermediate position state or mechanical shaking, thereby reducing the risk of false power supply.

[0059] In the "locking to position" state, the control unit does not immediately connect the needle type conductive connector 400, but provides a buffer time for the slight deformation rebound and contact stability after locking to position through the preset delay time of 0.5s to 3s. Such processing can reduce the contact failure caused by instantaneous instability, and help improve the reliability of power supply and signal transmission. Correspondingly, when determining the "lowering to position" state, the control unit will immediately disconnect the electric connection, so that the needle type conductive connector 400 is no longer in conduction with the conductive contact block of the gyroscopic sensitive part, thereby avoiding the power consumption and signal interference of the device in the non-working state, and helping to improve the energy efficiency management of the system.

[0060] In some embodiments, the control unit 600 is arranged outside the locking and releasing shell 100 and is electrically connected with the travel detection assembly 500 and the needle type conductive connector 400 through a cable. Optionally, the control unit 600 adopts an industrial programmable logic controller (PLC), an embedded microcontroller unit (MCU) or a single-chip microcomputer system with a digital input and output interface, which can include a signal acquisition circuit, a logic processing circuit and a drive control circuit inside. The control unit 600 receives the travel signal output by the micro travel switch 510 of the travel detection assembly 500 through the signal acquisition circuit, and determines the locking to position and lowering to position states by the logic processing circuit; when determining the locking to position state, the control unit 600 sends a control instruction through the drive control circuit after a delay preset time (for example, 2s), so as to drive the needle type conductive connector 400 to establish an electric connection with the conductive contact block of the gyroscopic sensitive part; when determining the lowering to position state, the control unit 600 sends a disconnection instruction to immediately cut off the electric connection of the needle type conductive connector 400. The control unit 600 is preferably arranged in an independent electric control box outside the locking and releasing shell 100 and is electrically connected with the travel detection assembly 500 and the needle type conductive connector 400 through a cable, so as to ensure compact arrangement, reliable signal transmission, and facilitate maintenance and replacement.

[0061] In order to facilitate understanding of the actual application mode of the device, the use process of the gyroscopic directional instrument ring type locking device of this embodiment will be described in combination with its structure and action mechanism.

[0062] Before the device is put into use, the operator needs to place the gyro-sensitive part in the circular through hole in the center of the locking and releasing shell 100, so that the outer wall is in the range of action of the three sets of locking mechanisms 200. At this time, the three sets of locking mechanisms 200 are in a radial release state, and the gyro-sensitive part can be smoothly placed and initially centered, thereby avoiding hard contact and unnecessary interference during installation. Before starting clamping, each limiting screw 213 should be in a loosened state to avoid interference with self-centering and stress distribution during radial feeding.

[0063] After the placement is completed, the control unit 600 issues a locking instruction to each radial drive mechanism 300, and each servo motor is synchronously started to drive the transmission rod 330 to rotate. The rotary motion is converted into axial displacement through the cooperation of the lifting wedge block 340 and the connecting hole 211, and is further converted into radial advancement under the action of the wedge-shaped guide. As the locking seat 210 moves inward with the locking block 220, the three sets of clamping points simultaneously act on the outer wall of the gyro-sensitive part, realizing ring-wise three-point balanced clamping. The compression spring 230 provides flexible compensation during clamping to make the stress distribution more uniform.

[0064] After the clamping stroke approaches the end point, the micro travel switch 510 will be triggered to output a locking-in-place signal, which is used by the control unit 600 to confirm that the clamping action is completed. After confirming that the locking is in place, the operator tightens the limiting screw 213 so that the limiting end cooperates with the limiting part on the gyro-sensitive part to form an additional mechanical fixation; this step is used to suppress micro-sliding and creeping in scenarios of vibration, impact or long-term loading. At the same time, the needle-type conductive connector 400 contacts the conductive contact block of the gyro-sensitive part at the end stage of radial clamping, and the control unit 600 controls the needle-type conductive connector 400 to establish electrical connection with the conductive contact block of the gyro-sensitive part after a delay of 0.5-3 seconds. In this way, mechanical clamping and electrical closure are completed simultaneously by the same action, which not only ensures the stable positioning of the gyro-sensitive part, but also ensures the reliable transmission of signals or currents.

[0065] When the gyro-sensitive part needs to be released, the control unit 600 issues a reverse command to the servo motor, and the transmission rod 330 rotates in reverse, at which time the locking seat 210 drives the locking block 220 to gradually move radially outward, thereby releasing the constraint on the gyro-sensitive part. Before unlocking, the limiting screw 213 should be loosened to release the additional fixation, and then the unlocking action is performed, to avoid hard friction between the limiting end and the gyro-sensitive part during the return stroke. When the locking block 220 is completely withdrawn to the release position, the other micro travel switch 510 is triggered to output a release-in-place signal, indicating that the device is in an unlocked state, so that the gyro-sensitive part can be smoothly removed.

[0066] During the whole use, the cooperation of the driving mechanism and the guiding structure ensures the displacement transmission path simple and the direction clear, and avoids the motion deviation caused by the additional torque or the partial load. The double position feedback provided by the stroke detection assembly makes the clamping and releasing process under the state identification of the monitorable, and the operation safety and reliability can be better guaranteed, so as to realize the stable and repeatable ring type locking and releasing of the gyro sensitive part.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that; it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
