Description

Technical Field

[0001] The present invention relates to the technical field of aerospace rocket testing, and particularly to an automatic separation and connection device for unplugging or plugging connectors. Background Art

[0002] In the comprehensive testing (desktop test) of the rocket control system, the module flight test items involving plugging and unplugging connections and separations require manual operation by operators. Due to the large spring force of the plugging and unplugging connections, it is quite strenuous for operators to manually connect, and it is easy to have an imbalance in the force control of both hands, resulting in misalignment of the head end and seat end of the connector and damage to the pins. Improper torque control when manually turning the handle at the tail of the connector is also likely to damage the pins. At the same time, when unplugging and separating, a large number of personnel are needed to support the unplugging or pull out the plugging, which increases the probability of human error, reduces the test efficiency, and has a low automation rate. With the increase in the number of rocket launch missions, the personnel allocation has become increasingly tense, while the requirement of completing the comprehensive test with high quality and high efficiency remains unchanged. Only by improving the automated test level of the comprehensive test can the dependence on personnel be reduced. According to the usage characteristics of unplugging and plugging in the comprehensive test, by using a miniaturized and low-cost unplugging or plugging connection and separation device, it is possible to facilitate installation, reduce human operation errors, improve the test efficiency, and achieve an improvement in the automated test level at a lower cost.

[0080] Embodiment

[0081] (1) Use guide rails to constrain the centering of the plug and socket of the plug-in or split connector

[0082] In this example implementation, two cylindrical hollow guide rails 12 are installed in parallel. The two ends of the guide rails are respectively fixed on the left end panel 24 and the right end panel 25. The two ends of the plug-in socket 21 and the plug 20 are constrained on the guide rails through the mother and son fixing panels 1, 18, 2, 19, linear bearings 13, and guide rail fixing seats 11. The fixing panel 1 at the socket end can slide on the guide rail 12 and is fixed on its respective panel after the plug-in socket 21 and the plug 20 are connected. After the plug-in is separated, the fixing panel 1 at the socket end translates along the guide rail 12 under the constraint of the guide rail, so that the plug-in socket 21 and the plug 20 can be centered and connected again during connection. See Figures 1 to 3 as shown.

[0083] (2) The sub-panels for fixing the connector head and socket are replaceable to be compatible with different models of connectors

[0084] In this example implementation, a JF2A plug-in socket 21 and a plug 20 are used. The inner edge shape of the sub-panels 18 and 19 is designed according to the JF2A plug-in shape (by replacing the sub-panels, it can be compatible with various models of plug-ins or split connectors such as JF2B, JF3, YF15A, YF8, CFH1, etc.), and the outer edge shape remains fixed. The sub-panels 18 and 19 are fixed on the mother panels 1 and 2 by screws. There is a certain fitting gap between the mother and son panels for adjusting the large position deviation during the initial centering of the plug-in socket 21 and the plug 20. Flexible gaskets 26 and 27 with a thickness of about 1 - 2 mm are covered between the fitting surfaces of the sub-panels 18, 19 and the ends of the plug 20 and the socket 21 for adaptively adjusting the small position or angle deviation during plug-in connection. See Figure 4 as shown.

[0085] (3) Use a dual protection method of machinery and program to prevent damage to the connector during the connection process

[0086] In this embodiment, the connection sequence of the JF2A plug-in / disconnection socket 21 and plug-in / disconnection plug 20 is: the plug-in / disconnection handle sleeve 3 rotates counterclockwise to the bottom - the pull rod 8 contracts to press and clamp the plug-in / disconnection socket 21 and plug-in / disconnection plug 20 - the handle rotates clockwise to the bottom - the handle rotates 45° counterclockwise. The connection relationship between the central control rotating assembly and the plug-in / disconnection handle is: hollow rotating platform 5 - damping shaft 4 - plug-in / disconnection handle sleeve 3 - plug-in / disconnection handle.

[0087] Program protection: 1. During the contraction of the pull rod 8, the socket 21 is driven forward. When it is stuck in place, the position sensor 29 receives a signal, and the pull rod 8 stops contracting and turns into an extended state; 2. The operation of the stepper motor of the hollow rotating platform 5 is controlled by the program. The single-chip microcomputer collects the current of the motor driver in real time to adjust the stepper motor torque, thereby controlling the torque applied to the plug-in and unplug handle to protect the plug-in and unplug handle from damage in abnormal situations.

[0088] Mechanical protection: 1. Add a limit sleeve 14 to the retracting rod 8. When the position sensor 29 is stuck or the program is abnormal, the pull rod 8 continues to retract after the unplugging socket 21 and the unplugging plug 20 are connected and stuck, which may cause the pin to be forced to be crooked. After adding the limit sleeve 14, the pull rod 8 is retracted to the predetermined position because the limit sleeve 14 supports the fixed plate 2, and the pull rod limit 8 cannot continue to retract, thereby preventing the unplugging socket 21 from being forced onto the unplugging plug 20. 2. The maximum torque value of the damping shaft 4 can be adjusted to set the maximum torque applied to the handle sleeve 3. When the electrical control system is abnormal, the abnormal large torque will be removed by the slipping of the damping shaft 4 to prevent it from being applied to the unplugging handle sleeve 3, thereby achieving the purpose of protecting the unplugging. See Figure 4 , Figure 5 shown.

[0089] (4) After installation, the connector head is fixed and separated by moving the base end

[0090] In the present implementation, the JF2A detachable plug 20 is fixed on the guide rail 12 through the daughter board 19, the mother board 2 and the guide rail fixing seat 11, and the detachable socket 21 is constrained on the guide rail 12 through the daughter board 18, the mother board 1 and the linear bearing 13, and can move forward and backward relative to the detachable plug 20. When the linear pull rod 8 contracts, it drives the detachable socket 21 to move toward the detachable plug 20. After moving to the stuck position of the detachable socket 21 and the detachable plug 20, the pull rod 8 is extended to the maximum position. Since the structure of the detachable plug 20 is more complicated than that of the seat end, the detachable plug 20 part has a rotating handle connected to the handle sleeve 3, and the tail of the handle has a separation pin connected to the strong detachment pull rope 9. At the same time, the ground cable connected to the detachable plug 20 is thick and bulky, resulting in the detachable plug 20 being subjected to a large torque of the ground cable and not easy to move. Therefore, the detachable plug 20 is fixed and the separation connection is achieved through the relative movement of the detachable socket 21, which can reduce the control force and reduce the wear of the device. See Figure 4 , Figure 5 shown.

[0091] (5) The rear end of the connector separation seat captures passive anti-rebound through gravity and magnetic attraction

[0092] In this example implementation, when JF2A is unplugged and separated, the spring force inside the unplugging plug 20 is released, and the unplugging plug 20 is fixed on the guide rail 12, causing the unplugging socket 21 to move away from the head end at a certain speed and hit the left end plate 24. A hydraulic buffer device 15 is installed on the left end plate 24, and a magnetic attraction capture device 16 composed of a magnet and a spring plunger. When the unplugging socket 21 hits the left end plate 24, it is first attracted by the magnetic attraction capture device 16, and then the speed is reduced to 0 by the hydraulic buffer device 15 to prevent it from rebounding and hitting the unplugging plug 20 again. By adjusting the support of the device bracket 17-1, the guide rail 12 forms an angle of 10° to 20° with the horizontal plane, making the unplugging socket 21 of the unplugging socket lower and the unplugging plug 20 higher. The rear seat end 20 of the separation naturally slides to the leftmost stable state under the action of the gravity component, further ensuring the stable state where the unplugging socket 21 and the unplugging plug 20 are far away from each other after separation. See Figure 2 and Figure 5 shown.

[0093] (6) Use a hollow rotating device to provide a tightening torque to the screwing handle end of the connector

[0094] In this example implementation, there is a separation pin at the tail of the screwing handle of the JF2A unplugging plug 20. Use a central control rotating platform 5 (providing a rotating torque) - a hollow damping rotating shaft 4 (limiting the torque value) - a central control handle sleeve 3 (connecting the handle) to connect to the unplugging screwing handle. Pass the pulling rope 9 on the separation pin through the hollow part and connect it to the electric pull rod 6 to achieve non-interference between the handle rotation control and the separation pin control in terms of structure. See Figure 4 and Figure 5 shown.

[0095] (7) Integrated control electrical box, which can achieve distributed or centralized control of single or multiple devices

[0096] In this example implementation, a 24v to 5v DC power supply module (powering the position sensor, sound and light alarm, and single-chip microcomputer) is integrated in the electrical control box 7, an STM32 single-chip microcomputer development board (receiving / executing control instructions, information processing, communication), a stepping motor driver module to drive the hollow rotating platform, and two DC motor driver modules to drive the pull rod 8 and the strong unplugging push rod 6 respectively. All the above modules are installed on a PCB bottom board. There are strong unplugging buttons, handle rotation buttons, and connection buttons on the control box. These three buttons can achieve manual control of the separation and connection of the unplugging. The reset button is used for reset when there is an abnormality in connection, separation, or program; the switch button is used to control the connection of the external 24V DC power supply. See Figure 5 and Figure 6 shown.

[0097] The STM32 single-chip microcomputer development board is equipped with an RS232 serial port and a network port. When controlling a single device or multiple devices centrally, the host computer controls each device by sending commands to the serial port respectively; when performing distributed control, a network switch is used. Each device is assigned a different IP address, and signals are sent or received through multicast UDP. See Figure 8 as shown.

[0098] (8) Add status flag discrimination and fault diagnosis discrimination in electrical control

[0099] In the implementation of this example, the device has 5 photoelectric position sensors, namely: 1. The separation-in-place position sensor 30. When the distance between the unplugging socket 21 and the unplugging plug 20 is greater than a certain distance, it is considered that the separation is good; 2. The head seat clamping-in-place position sensor 29. When the distance between the unplugging socket 21 and the unplugging plug 20 is less than a certain distance, it is considered that the clamping is in place; 3. The connection-in-place sensor 10. After the clamping is in place, the unplugging handle needs to be rotated, and the unplugging socket 21 continues to move forward. When the distance between the unplugging plug 20 and the unplugging socket 21 is less than a certain distance, it is considered that the connection is in place. 4. The retraction-in-place position sensors 28 for the pull rods 1 and 2. When the pull rod 8 extends to the position where the sensor 28 responds, it is considered that the retraction is in place. The single-chip microcomputer receives the status signals of the sensors and combines the issued execution signals to determine whether the device has normally completed the execution process of the command. For example, when the single-chip microcomputer receives the unplugging and connecting command issued by the host computer, the execution process is as Figure 7 shown. If the connection good signal is not received within the specified time, it is considered that the connection is abnormal, and the sound and light alarm device is activated and the corresponding status flag bit is set. When the host computer sends a query command, an abnormal status flag code is sent. Once in an abnormal state, it must be reset by an operator pressing the reset button, and the control commands received in the abnormal state will not be executed.

[0100] (9) The device is equipped with an inclination adjustment bracket, which can be detachably separated

[0101] In the implementation of this example, the unplugging and connecting separation device is fixed using an aluminum profile bracket 17. The inclination of the device is adjusted by adjusting the height of one side of the device bracket support 17-1. The bracket is about 550 mm long, 300 mm wide, and 720 mm high. In actual use, the bracket is placed on the ground next to the test table. The ground unplugging plug 20 passes through the inside of the bracket 17 and is fixed to the device, and the unplugging socket 21 is led out from the test table and fixed to the first sub-panel 18 of the device. The bracket 17 is equipped with brake wheels for easy overall movement and fixation. When it is required to be used as a plugging and unplugging device, since the plugging and unplugging heads, sockets and their lead-out cables are all on the test table, the device needs to be placed on the test table without the bracket. The device is placed on the table separately by removing the connection screws between the device and the bracket 17. See Figure 3 and Figure 4 as shown.
