Light press type operation tool storage platform capable of preventing instantaneous impact

Abstract

The invention provides a light pressing type operation tool storage platform capable of preventing instantaneous impact, and belongs to the technical field of space robots. The problems that an opening and closing mechanism is low in rigidity, a cover plate is poor in impact load resistance, and tools are prone to disengagement under the condition that multiple tools are arranged in parallel in an existing space on-orbit operation tool storage platform are solved. The device comprises an opening and closing driving mechanism, a triangular bracket type anti-impact cover plate mechanism, a tool bracket and a spring buffer mechanism, and has the capability of actively and passively resisting tool impact, and in order to reduce the impact load momentum, the passive spring buffer mechanism is designed on a cover plate, so that the instantaneous impact force is effectively reduced; the cover plate opening and closing driving mechanism is in a mode that a small driving motor is combined with a large-reduction-ratio harmonic reducer, and the passive impact resistance of the opening and closing mechanism is improved. Under the impact effect, the multiple tools distributed in parallel can generate corresponding impact force on the cover plate to enable the cover plate to overturn, and therefore the triangular support type anti-impact cover plate mechanism is designed, deformation of the cover plate is effectively resisted, and the tools are prevented from escaping.

Description

technical field [0001] The invention belongs to the technical field of space robots, and in particular relates to a light-weight pressing-type operating tool storage platform with anti-instantaneous impact. Background technique [0002] With the development of technology, the tasks to be completed by the space on-orbit manipulator are becoming more and more complex. From the analysis of the current space robots, it can be seen that all countries are equipped with different operating tools through a standard interface to complete different work tasks, so it is suitable for space robots. The operation tool storage platform for the robotic arm to pick and place operation tools has become an indispensable and important research object. Considering that the instantaneous large load of the launch and the large vacuum temperature difference and weightlessness environment in space may easily cause the tool in the operation tool storage platform to be damaged or even come out of the ...
