Technical Field

The invention relates to a multi-degree-of-freedom rapid positioning and locking mechanism at the rear end of a vertical arm.

Background

With the development of aerospace technology, the launching mode of 'three-horizontal-vertical' (horizontal assembly, horizontal test, horizontal transfer and vertical launching scheme) starts to be widely applied in commercial aerospace. Based on the characteristics of a 'three-horizontal and one-vertical' launching mode of a carrier rocket, the locking mechanism of the rear locking mechanism plays a role in supporting, positioning and locking the rocket in the horizontal transferring and vertical erecting processes of the rocket. And the rear end locking needs to adapt to the position difference of the rear end positioning shafts or the positioning shafts of the switching disc of different rockets, and the purposes of quick positioning locking and unlocking are achieved. At present, most of the mechanisms on the ground equipment for launching the carrier rocket in a three-horizontal and one-vertical mode are multi-degree-of-freedom linkage mechanisms, the debugging work of a positioning surface and a limiting device is complicated, the time required for positioning, locking and unlocking is more, and the preparation workload of the rocket before launching in a launching site is large.

Disclosure of Invention

In order to solve the technical problems, the invention provides a multi-degree-of-freedom rapid positioning and locking mechanism at the rear end of a vertical arm, which can effectively meet the requirements of rapid positioning, rapid locking and rapid unlocking of a carrier rocket.

The invention is realized by the following technical scheme.

The invention provides a multi-degree-of-freedom rapid positioning and locking mechanism at the rear end of a vertical arm, which comprises a lifting screw conveyor arranged on the vertical arm; the lifting screw machine is fixedly provided with a lifting guide cylinder, a lifting screw machine action shaft is fixedly provided with a lifting guide shaft, the lower end of the lifting guide shaft is sleeved in the lifting guide cylinder, an upper mounting seat is fixedly arranged at the upper end of the lifting guide shaft, and a rocket is arranged on the upper mounting seat.

The locking screw machine is arranged at the side end of the upper mounting seat and drives the locking hook to move horizontally along the upper mounting seat.

A positioning block is arranged on the upper mounting seat and fixed beside the lock hook.

And a positioning screw rod is arranged at the other end of the upper mounting seat opposite to the end where the locking screw machine is positioned, and the positioning screw rod can drive the lock hook to move.
