The structure of described locating flange component is that keeper one end of cylindricality is provided with locating flange, and the other end is provided with lockTight ring flange, locking ring flange is provided with the limited block of circle distribution, and limited block is flexibly connected with locking jaw；In locking ring flangeUpper circle distribution has the locking face of wedge shape.
The outside of gear wheel and little gear described in described monitor component is provided with gear protective cover, in gear protective coverProvided with the video camera with runing rest.
Described threaded rod is provided with mobile plectrum, in base top provided with three proximity switches, three proximity switches according toIt is secondary to be located on the path of mobile plectrum.
The method positioned using positioning and locking device to Aircraft Tools skeleton, is comprised the following steps：
1）By the monitoring of the video camera on monitor component, the front end of locating flange component is arranged on by control needs positioningFrock skeleton on；
2）Start two-phase stepping motor I, alignment pin is protruding, and is inserted into the positioning hole of frock skeleton to be positionedInterior, now the positioning hole of frock skeleton and locating flange component are coaxial；
3）Start two-phase stepping motor II and drive pinion rotation, and by the bull gear drive of engagement, so as to drive lockThe locating flange of locating flange component and frock are positioned clamping skeleton locking and are connected by tight flange disc spins, wedge lock face.
This is used for the electronic positioning and locking device of Aircraft Tools skeleton using locking positioning component, locating flange component and monitoringThe structure that component is combined, so that positioning is more accurate, quick.
Locking positioning component drives threaded rod to rotate using two-phase stepping motor II, so that alignment pin can stretch certainlySuch as, alignment pin is made to position frock skeleton, while driving locating flange component to rotate wedging by gear engagement.
On locating flange component set limited block be connected with locking jaw, circumference setting lozenges, in order to frock skeletonCarry out wedging connection.
Position for video camera, in order to observe the position of positioning hole, makes positioning more accurate in gear protective cover.
Mobile plectrum on threaded rod can control the stroke of alignment pin by proximity switch.
The association that the method positioned using positioning and locking device to Aircraft Tools skeleton passes through two stepper motors of controlTransfer and make, so as to control locating flange quickly to be positioned with frock skeleton.
