[0068] The present application provides an automatic simulation test equipment for a quick connector, which includes a socket and a plug. The test equipment includes a locking and unlocking device, a plug-in driving device and a position monitoring device. The socket and the plug are locked and unlocked by the locking and unlocking device. The plug-in driving device is drivingly connected with the plug, and the plug is driven to be inserted into or pulled out of the socket by the plug-in driving device. The position monitoring device is used to monitor the locking state and the unlocking state of the locking and unlocking device, and whether the plug is inserted into or pulled out of the socket. In the technical field, the locking and unlocking device, the plug-in driving device and the position monitoring device are all mature technologies, and therefore, the specific structure of these devices is not limited in the present application. The present application aims to automatically simulate the plug-in and pull-out, locking and unlocking of the quick connector, and high-frequency recirculation, thereby saving manual single, multiple or repeated operations. The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0069] Please refer to Figure 1 The automatic simulation test equipment for a quick connector according to the present embodiment includes a test base plate 5, a test vertical plate 4, a locking and unlocking device 2, a plug-in driving device 6 and a position monitoring device. The test vertical plate 4 is fixedly arranged on the test base plate 5.

[0070] The plug-in driving device 6 is arranged on the test base plate 5. The plug-in driving device 6 includes a second driving motor 605, a screw rod and sliding block mechanism and a sliding table 601. The second driving motor 605 is drivingly connected with the sliding table 601 through the screw rod and sliding block mechanism, and the plug 1 is fixed on the sliding table 601 by a clamp. In the present embodiment, the clamp 14 includes an upper clamp 1401 and a lower clamp 1402. The upper clamp 1401 is fixed on the lower clamp 1402 by a threaded fastener, and the lower clamp 1402 is fixed on the sliding table 601.

[0071] The screw rod and sliding block mechanism is mature technology in the field, and the present application does not make specific limitations thereto. In the present embodiment, the screw rod and sliding block mechanism comprises a base 604, a screw rod 603 and a sliding block 602, and the base 604 is fixed on the test base plate 5. The base 604 is provided with a sliding rail 6041, and the sliding block 602 is slidingly arranged on the sliding rail 6041. The second driving motor 605 is fixed at one end of the base 604 and is drivingly connected with the screw rod 603. The screw rod 603 is rotatably arranged on the base 604. The sliding table 601 is threadedly connected with the screw rod 603, and the sliding table 601 is fixedly connected with the sliding block 602. In the present embodiment, the rotation of the second driving motor 605 is converted into the linear reciprocating motion of the sliding table 601 through the screw rod and sliding block mechanism, so that the plug-in and plug-out of the plug 1 is realized by the plug-in and plug-out driving device 6.

[0072] Along the length direction of the base 604, one side of the base 604 is provided with a C-shaped guide rail 7, and the opening of the C-shaped guide rail 7 faces outward.

[0073] The position monitoring device comprises an inductive plate 10, a first photoelectric proximity switch 11 and a second photoelectric proximity switch 9 matched with the inductive plate 10, and the first photoelectric proximity switch 11 and the second photoelectric proximity switch 9 are arranged in a spaced manner along the moving direction of the plug 1. The inductive plate 10 is fixedly arranged opposite to the plug 1. Specifically, the first photoelectric proximity switch 11 is slidingly arranged on the C-shaped guide rail 7 through a first support, the second photoelectric proximity switch 9 is slidingly arranged on the C-shaped guide rail 7 through a second support 8, and the second photoelectric proximity switch 9 is closer to the second driving motor 605 than the first photoelectric proximity switch 11. The inductive plate 10 is fixed on the sliding table 601. When the inductive plate 10 approaches the first photoelectric proximity switch 11, the plug 1 is inserted into position, please refer to Figure 14 ; when the inductive plate 10 approaches the second photoelectric proximity switch 9, the plug 1 is pulled out into position, please refer to Figure 17 .

[0074] The plug 1 comprises an insertion part 101, and the insertion part 101 is a non-circular structure, that is, the insertion part 101 is not circular, for example, an elliptical shape, a rectangular shape, a regular polygon or an irregular image, and the like. In the present embodiment, the insertion part 101 is preferably an elliptical shape. The socket 3 is provided with a slot 301 matched with the insertion part 101. In the present embodiment, the shape of the slot 301 is the same as that of the insertion part 101, and the slot 301 is slightly larger than the insertion part 101. When the two are connected, the insertion part 101 is inserted into the slot 301.

[0075] The socket 3 is fixed on the test vertical plate 4. In the present embodiment, the test vertical plate 4 is provided with a mounting hole for mounting the socket 3, and the socket 3 is fixedly mounted on the mounting hole.

[0076] Please refer toFigures 2 to 13 The locking and unlocking device 2 comprises a clamping blade 203 and a power driving mechanism which is drivingly connected with the clamping blade 203. The clamping blade 203 is provided with a non-circular hole 2031 which is adapted to the insertion part 101. When the two are connected, the insertion part 101 is inserted into the slot 301 through the non-circular hole 2031, the power driving mechanism drives the clamping blade 203 to rotate, and the clamping blade 203 abuts against the insertion part 101 to limit the movement of the insertion part 101 in the pulling-out direction. When the insertion part 101 is inserted into the slot 301, one end surface of the insertion part 101 is located in the slot 301, and the other end surface is located outside the slot 301. The end surface is in contact with the clamping blade 203 to achieve the purpose of abutting the clamping blade 203 against the insertion part 101. Since the insertion part 101 and the non-circular hole 2031 on the clamping blade 203 are not circular structures, when the clamping blade 203 rotates, the insertion part 101 will stagger with the non-circular hole 2031 on the clamping blade 203, that is, the end surface of the clamping blade 203 will be in contact with the end surface of the insertion part 101. The clamping blade 203 limits the movement of the insertion part 101 in the pulling-out direction, so the insertion part 101 cannot be separated from the non-circular hole 2031 of the clamping blade 203, and the insertion part 101 cannot be separated from the slot 301 of the socket 3, thereby achieving the purpose of locking the plug 1 by the clamping blade 203. At this time, the locking and unlocking device 2 is in the locked state. Please refer to Figure 5 and Figure 12 When it is necessary to unlock the plug 1, the power driving mechanism drives the clamping blade 203 to rotate, and the clamping blade 203 is no longer in contact with the insertion part 101. Therefore, the clamping blade 203 no longer limits the movement of the insertion part 101 in the pulling-out direction, that is, the limitation of the movement of the insertion part 101 in the pulling-out direction is removed. At this time, the locking and unlocking device 2 is in the unlocked state. Please refer to Figure 4 and Figure 13 The plug 1 can be pulled out of the socket 3.

[0077] In the embodiment, the plug 1 comprises a plug body 103 and an insertion part 101 which is integrally arranged at one end of the plug body 103. The outer periphery of the connection between the insertion part 101 and the plug body 103 is provided with an annular groove 102. When locked, the clamping blade 203 is in contact with the end surface of the insertion part 101 which faces the plug body 103 through the annular groove 102 to abut against the insertion part 101, thereby achieving the purpose of locking the insertion part 101 by the clamping blade 203. In the embodiment, the plug body 103 and the insertion part 101 are integrally formed, and the shape and size of the plug body 103 are the same as those of the insertion part 101.

[0078] The power driving mechanism can directly drive the clamping knife 203, or drive the clamping knife 203 through transmission, and the present application does not make any limitation. In this embodiment, the power driving mechanism includes a power mechanism and a transmission mechanism, and the power mechanism is drivingly connected with the clamping knife 203 through the transmission mechanism. The power mechanism can be an electric device, a pneumatic device or an oil cylinder, and the transmission mechanism can be a belt transmission, a gear transmission, a chain transmission, a worm gear transmission or a screw transmission, and the present application does not make any specific limitation. In this embodiment, the power mechanism includes a first driving motor 208, and the transmission mechanism includes a gear 207 and an arc-shaped gear rack 214, and the gear 207 is fixedly connected with an output shaft of the first driving motor 208. The clamping knife 203 is in a disc type structure, the arc-shaped gear rack 214 is fixed on the outer periphery of the clamping knife 203, and the gear 207 is engaged with the arc-shaped gear rack 214. In this embodiment, the arc-shaped gear rack 214 is externally engaged with the gear 207, and thus the rotating direction of the gear 207 is the same as that of the first driving motor 208, and the rotating direction of the arc-shaped gear rack 214 is opposite to that of the first driving motor 208, and thus the rotating direction of the clamping knife 203 is opposite to that of the first driving motor 208.

[0079] In this embodiment, the clamping knife 203 is in a disc structure, and the arc-shaped gear rack 214 is integrally formed on the outer periphery of the clamping knife 203, and the arc-shaped gear rack 214 is concentric with the clamping knife 203.

[0080] In order to facilitate the installation of the clamping knife 203 and the power driving mechanism, the locking and unlocking device 2 further includes a mounting seat, the mounting seat is fixed on the socket 3, the clamping knife 203 is rotatably arranged on the mounting seat, and the power mechanism is mounted on the mounting seat.

[0081] In this embodiment, the mounting seat includes a bottom plate 211 and a face plate 202, the bottom plate 211 is fixedly connected with the socket 3, and the bottom plate 211 is fixed on the test vertical plate 4. The clamping knife 203 is rotatably connected with the bottom plate 211 through a bearing 213.

[0082] Please refer to Figure 8 The side of the bottom plate 211 facing the clamping knife 203 is provided with an annular stepped boss 2113, the annular stepped boss 2113 includes a first circular boss 21132 and a second circular boss 21131, the first circular boss 21132 is located outside the second circular boss 21131, the bearing 213 is sleeved on the second circular boss 21131, the inner ring end face of the bearing 213 abuts against the first circular boss 21132, and the outer ring end face of the bearing 213 is in suspension, so as to ensure that the outer ring end face of the bearing 213 does not directly contact with the bottom plate 211 to cause clamping.

[0083] The bottom plate 211 is provided with a first guide hole 2112 for guiding the insertion of the insertion part 101 into the socket 301. The first guide hole 2112 penetrates the second circular ring boss 21131.

[0084] The card cutter 203 is provided with an annular stepped groove 2032 on the side of the bottom plate 211. Please refer to Figure 7 The annular stepped groove 2032 includes an inner groove 20321 and an outer groove 20322, and the outer groove 20322 is connected to the outer periphery of the inner groove 20321. The bearing 213 is embedded in the outer groove 20322, and the outer ring end face of the bearing 213 abuts on the groove bottom of the outer groove 20322; the inner ring end face of the bearing 213 is suspended through the inner groove 20321. The purpose is that when one end of the bearing 213 is embedded in the card cutter 203, the inner ring of the bearing 213 will not directly contact the card cutter 203 to cause jamming.

[0085] The panel 202 is fixedly connected with the bottom plate 211, such as being connected by threaded fasteners such as studs 205 or being connected by other fasteners. The card cutter 203 is located between the panel 202 and the bottom plate 211, and the panel 202 abuts against the card cutter 203.

[0086] Please refer to Figure 9 The panel 202 is provided with a second guide hole 2021 for guiding the insertion of the insertion part 101 into the socket 301. The socket 301 on the socket 3, the first guide hole 2112 on the bottom plate 211, the non-circular hole 2031 on the card cutter 203, and the second guide hole 2021 on the panel 202 are all oval holes with the same shape and size as the insertion part 101. The socket 301 on the socket 3, the first guide hole 2112 on the bottom plate 211, the non-circular hole 2031 on the card cutter 203, and the second guide hole 2021 on the panel 202 are sequentially connected to form a channel for the movement of the insertion part 101.

[0087] The panel 202 is provided with a plurality of hemispherical protrusions 2022 for axial positioning of the card cutter 203 on the side facing the card cutter 203. The circular bottom surface of the hemispherical protrusion 2022 is fixedly connected with the panel 202, and the spherical surface of the hemispherical protrusion 2022 abuts against the card cutter 203. In this embodiment, the plurality of hemispherical protrusions 2022 are arranged at intervals around the outer periphery of the second guide hole 2021. The contact area between the hemispherical protrusion 2022 and the card cutter 203 is small, and the friction is small.

[0088] In order to prevent the first drive motor 208 from rotating excessively, the bottom plate 211 is further provided with two limiting columns on the side facing the card cutter 203, which correspond to the two ends of the arc-shaped rack 214 respectively. When the card cutter 203 rotates, please refer to Figure 10When one end of the arc-shaped rack 214 contacts one of the limit posts 212, or when the other end of the arc-shaped rack 214 contacts the other limit post 212', the card blade 203 stops rotating. That is, the two limit posts limit the bidirectional rotation of the card blade 203 by contacting the two ends of the arc-shaped rack 214 on the card blade 203. Figure 11

[0089] In this embodiment, the bottom plate 211, the panel 202, and the card blade 203 are all made of low-temperature-resistant materials, and the surfaces contain low-temperature-resistant coatings, which are used to prevent sticking, water, condensation, or icing when cooling or conducting.

[0090] In this embodiment, in order to monitor whether the insertion part 101 is inserted into place (i.e., whether the insertion part 101 is inserted into the insertion slot 301 of the socket 3 to a specified position), the locking and unlocking device 2 further includes a first monitoring device for monitoring whether the insertion part 101 is inserted into place, which includes a first magnet 201 and a first magnetic proximity switch 209 adapted to the first magnet 201. The first magnet 201 is arranged on the insertion part 101, and the first magnetic proximity switch 209 is arranged on the bottom plate 211. When the first magnet 201 reaches the front of the first magnetic proximity switch 209, the insertion part 101 is inserted into place; otherwise, the insertion part 101 is not inserted into place.

[0091] The locking and unlocking device 2 further includes a second monitoring device for monitoring the state of the card blade 203, which includes a second magnet 204 and a second magnetic proximity switch 206 and a third magnetic proximity switch 210 adapted to the second magnet 204. The second magnet 204 is arranged on the side of the card blade 203 facing the bottom plate 211, and further, the second magnet 204 is located on the side of the arc-shaped rack 214. The second magnetic proximity switch 206 and the third magnetic proximity switch 210 are arranged on the bottom plate 211 in a spaced manner. When the second magnet 204 reaches the front of the second magnetic proximity switch 206, the card blade 203 is locked into place when rotating, please refer to Figure 12 ; when the second magnet 204 reaches the front of the third magnetic proximity switch 210, the card blade 203 is unlocked into place, please refer to Figure 13 .

[0092] In this embodiment, the position monitoring device further includes a first micro switch 12 and a second micro switch 13. The first micro switch 12 is located outside the second magnetic proximity switch 206 and is fixed on the test vertical plate 4. If the card blade 203 triggers the first micro switch 12 during the process of locking the plug, the card blade 203 is locked out of position, please refer to​Figure 15 The second micro switch 13 is located outside the third magnetic proximity switch 210 and fixed on the test riser 4. The first micro switch 12 and the second micro switch 13 are respectively on both sides of the locking and unlocking device 2. When the card knife 203 is in the process of unlocking the plug, when the card knife 203 triggers the second micro switch 13, the card knife 203 is unlocked. Please refer to Figure 16 .

[0093] In this embodiment, when the plug 1 is fully inserted, the first magnet 201 is located directly in front of the first magnetic proximity switch 209, and the locking action is executed. That is, the first drive motor drives the card knife 203 to rotate forward. When the second magnet 204 rotates to the position directly in front of the second magnetic proximity switch 206, the second magnetic proximity switch 206 is triggered, and the card knife 203 is locked in place. If the second magnetic proximity switch 206 is not triggered, and the card knife 203 triggers the first microswitch 12, the card knife 203 has rotated too far, and the locking is recorded as over.

[0094] Please refer to Figure 19 This embodiment also provides a control system for automatic simulation test equipment for quick connectors, including a host computer 15 and a controller 607. The host computer 15 is electrically connected to the controller 607 and the locking and unlocking device 2, respectively. The controller 607 is electrically connected to the plug-in drive device 6 and the position monitoring device, respectively. Specifically, the host computer 15 communicates with the first drive motor driver 216 and the controller 607 via the RS485 communication protocol. The signals collected by the first magnetic proximity switch 209, the second magnetic proximity switch 206, and the third magnetic proximity switch 210 are fed back to the first drive motor driver 216, which drives the first drive motor 208. The signals collected by the first photoelectric proximity switch 11, the second photoelectric proximity switch 9, the first microswitch 12, and the second microswitch 13 are fed back to the controller 607, which controls the second drive motor driver 606, which in turn drives the second drive motor 605.

[0095] This embodiment also provides a control method for automatic simulation test equipment of a quick connector, please refer to Figure 20 , including the following steps:

[0096] S1. The host computer 15 issues an insertion command, the second drive motor 605 rotates forward, and drives the plug 1 to perform a linear insertion motion. When the first magnetic proximity switch 209 determines that the plug is inserted in place, the locking signal is triggered; if the first magnetic proximity switch 209 does not trigger the insertion in place signal, and the first photoelectric proximity switch 11 determines that the plug is inserted in place, the first magnetic proximity switch 209 is in a failed state at this time, the abnormality is recorded and counted, and the locking signal is triggered.

[0097] S2, after triggering the locking signal, the first motor rotates forward, driving the gear to rotate forward, and the locking blade 203 rotates reversely. When the second magnet 204 on the locking blade 203 is located in front of the second magnetic proximity switch 206, the second magnetic proximity switch 206 judges that the locking is in place, and then the upper computer 15 sends an unlocking instruction; if the second magnetic proximity switch 206 does not judge that the locking is in place, but the first micro switch 12 judges that the locking is in place, at this time, it is in the locking overtravel state, then the second magnetic proximity switch 206 is recorded as abnormal and counted, and then the upper computer 15 sends an unlocking instruction

[0098] S3, after the upper computer 15 sends an unlocking instruction, the first motor reverses, driving the gear to reverse, and the locking blade 203 rotates forward. When the second magnet 204 on the locking blade 203 is located in front of the third magnetic proximity switch 210, the third magnetic proximity switch 210 judges that the unlocking is in place, and then the upper computer 15 sends a pulling-out instruction; if the third magnetic proximity switch 210 does not judge that the unlocking is in place, but the second micro switch 13 judges that the unlocking is in place, at this time, it is in the unlocking overtravel state, then the third magnetic proximity switch 210 is recorded as abnormal and counted, and then the upper computer 15 sends a pulling-out instruction.

[0099] S4, after the upper computer 15 sends a pulling-out instruction, the second motor reverses and times, and the plug 1 moves linearly. When the second photoelectric proximity switch 9 judges that the pulling-out is in place, the second motor stops, and then the above S1, S2, S3 and S4 are repeated. Figure 18 The locking blade 203 contains a strain gauge for judging pressure. If the timing is overdue or the strain gauge pressure on the locking blade 203 is too large, it is judged that the pulling-out is abnormal. In order to prevent the second motor from continuing to run and damaging the test equipment, the test equipment as a whole stops working.
