Flexible capturing connection device and capturing connection method thereof

Abstract

The invention discloses a flexible capturing connection device and a capturing connection method of the device. The device comprises a driving capturing connection unit and a driven capturing connection unit. The driving capturing connection unit comprises an upper connecting rod, a flange disc, a spherical head shaft, lead springs, a capturing rod, a guide head and a lock tongue, and the upper connecting rod is connected with the spherical head end of the spherical head shaft through the flange disc; the lead springs are in the pretightening state and are connected between the spherical head shaft and the flange disc; the spherical head shaft is connected with the capturing rod which is connected with the guide head; the lock tongue is arranged on the outer side, close to one end of the guide head, of the capturing rod; and the driven capturing connection unit comprises a conical opening and a lock hook, and the lock hook is arranged at the conical end of the conical opening. When capturing is completed, the guide head enters the conical opening, and the lock hook and the lock tongue are in contact for compressing. The method comprises the steps that the guide head enters the conical opening; the lock tongue and the lock hook generate spring lock capturing; a shifting rod rotates to trigger a sensor; and the driving capturing connection unit moves upwards, and the lock tongue and the lock hook are in contact for compressing. The device and method are simple in structure, small in mass and large in capturing range.

Description

technical field [0001] The invention relates to the aerospace field, in particular to a flexible capture connection device and a capture connection method thereof. Background technique [0002] With the rapid development of space agencies, whether reliable capture and connection between two aircraft can be achieved directly affects the formation of the space station. However, due to the influence of the space environment and mechanism control precision, the two aircraft must be captured and connected in an environment with large position deviation and vibration shock, which requires the mechanism to complete this function to meet the requirements of large deviation capture, large connection force, high Accuracy and timely reset requirements. [0003] In the existing mechanisms for capturing connections, there are generally problems such as complex structures (such as docking mechanisms), large mass and volume, small capturing range, and low connection and retention capabili...
