Problems solved by technology

The traditional mechanical clamping device needs to adapt to the deformed mechanical system for positioning and fixing. Its structural design is very complicated, and the coordinated control is very difficult, and it is easy to generate large fastening stress and cause the attitude of the mechanical system to change.

Abstract

The present invention discloses a stressless space follower positioning equipment. It is characterized by that it has a base seat, the upper portion of said base seat is a cylindrical hollow cavity, the lower bottom surface of said hollow cavity is equipped with a plate-shaped heat-insulating layer, the inner wall of the cylindrical hollow cavity is equipped with a ring-shaped heat-insulating layer, in the heat-insulating layer interior a positioning sleeve is set, in the exterior of positioning sleeve an electric heater or electromagnetic coil is fixed, in the interior of said positioning sleeve a supporting bar is set, between the interior of positioning sleeve and supporting bar low-melting point metal or magnetorheologic fluid is filled, the supporting bar and bottom portion of said positioning sleeve are equipped with supporting spring respectively, in the upper portion of said supporting bar a heat-insulating plate and a supporting flange are fixed, and in the upper portion of said base seat an end cover is mounted.

Description

technical field [0001] The invention relates to a stress-free space follow-up positioning device. Background technique [0002] How to adjust a rigid mechanical system to a certain space state and make it reliably locked in this state is a problem often encountered in military, aviation, aerospace, geology, ocean and other fields. [0003] If a rigid mechanical system is fixedly connected to the platform by multiple support rod structures, and then the mechanical system is placed in a certain attitude by adjusting the platform, if during the attitude adjustment process of the rigid mechanical system or after the attitude adjustment is completed, the outside world imposes an additional force on the mechanical system force (such as local processing, heating deformation, etc.) Place on the platform until the stress on the mechanical system is completely relieved. If it is necessary to fix the mechanical system on the platform according to the current attitude through the supp...
