Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.
[0029] The invention provides an adaptive underactuated space capture device, which includes a housing, four evenly distributed lifting lugs, four evenly distributed centripetal thrust bearings, a chuck assembly, a torsion spring, and a flexible anti-friction anti-skid pad , pressure sensor, telescopic rod.
[0030] The device is mounted on the end arm of the service spacecraft's space robotic arm. The catching part drives the linkage mechanism by controlling the expansion and contraction of the piston rod of the hydraulic cylinder or driving the thread pair by the motor to make the chuck assembly close or expand, so as to achieve the effect of catching or releasing.
[0031] When the chuck assembly moves to the left under the drive of the telescopic rod, the closing effec...
