The application belongs to the technical field of aircraft structure design, and particularly relates to a multi-stage trigger type high-load locking mechanism, which mainly comprises a first locking ring (1), a blocking ring (2), an inner cylinder (3), a reversing device (4), a shaft (6), a release shaft sleeve (8), a second locking ring (9), a release lever (12) and a reset spring. The multi-stage trigger type high-load locking mechanism converts the force axially transmitted by the inner cylinder (3) into radial transmission, and transmits the force to the second locking ring (9) through the first locking ring (1) and the reversing device (4). The self-locking of the inner cylinder (3) is realized by the axial limiting of the second locking ring (9) through the release shaft sleeve (8). The release lever (12) drives the release shaft sleeve (8) to move, removes the axial limiting of the second locking ring (9), and realizes the unlocking of the inner cylinder (3). The application improves the bearing capacity of the mechanism, is stable and reliable in work, convenient to operate, and lower in cost.

The utility model discloses an AC shaft swing head which comprises a C shaft rotating mechanism, an A shaft rotating mechanism, a swing head base and a swing head main shaft, and the C shaft rotating mechanism comprises a first motor, a speed reducer and a C shaft brake assembly. The output end of the motor I is in transmission connection with the speed reducer, the output end of the speed reducer is connected with the C-axis brake assembly, a detachable connecting disc is arranged between the swing head base and the C-axis brake assembly, and the connecting disc is in power transmission connection with the swing head base and the C-axis brake assembly, so that the swing head base rotates around a C axis; the A-axis rotating mechanism is installed in the swing head base and comprises a second motor, a worm, a rotating tower, a time grating assembly and an A-axis brake assembly. The output end of the second motor is in transmission connection with a worm, the worm extends in the axial direction of the worm and is provided with spiral teeth, a plurality of rollers in meshing transmission with the spiral teeth are distributed in the circumferential direction of the rotating tower, one end of the rotating tower is connected with the time grating assembly and the A-axis brake assembly, the other end of the rotating tower is connected with the swing head main shaft, and the swing head main shaft rotates around the A axis.
