Rotary table device that can be raised and lowered in a large range

Abstract

The invention provides a rotary table device capable of lifting in a large range. The device comprises a bottom frame, a turning support, a lifting table and a rotating plate; the turning support is fixedly equipped with a plurality of guide rails which are vertical to a hinging shaft; a lifting driving mechanism is arranged between the lifting table and the turning support; the lifting table is in sliding connection with the guide rails and can be driven by the lifting driving mechanism to axially move along the guide rails; the rotating plate is mounted on the lifting table through a rotating plate bearing; a rotating driving mechanism is arranged on the lifting table to drive the rotating plate to rotate about the axis. The device has the characteristics of being high in assembling precision, wide in moving range and large in loading capacity; the processes of conveying instruments and apparatus during assembling in the ground can be decreased; the manmade operation risk can be reduced; the assembling efficiency can be increased; the operation time is saved; a lifting system mainly comprises four sets of guide rail pairs and a set of ball guide screw nut pairs; the guide rails are symmetrically arranged at the front, back, left and right; the positions of the sliding blocks are optimized to enable the guide rails to bear pressure, so as to ensure uniform bearing.

Description

technical field [0001] The invention relates to a turntable device, which is suitable for realizing the five-degree-of-freedom movement of heavy hardware products, especially in the upward and downward lifting directions, which can realize a large moving range and high displacement accuracy, and at the same time, It can realize the transshipment functions such as site conversion and station conversion. It is not only applicable to the field of spacecraft, but also to fields such as civilian equipment. Background technique [0002] After the success of my country's manned spaceflight and lunar exploration projects, large spacecraft will become the focus of my country's spaceflight development in the future, and the installation and testing of test instruments and equipment on satellites will be more and larger. , the weight is relatively large, which poses a challenge to the ground assembly, and some instruments and equipment need to be assembled and moved repeatedly.

Problems solved by technology

[0002] After the success of my country's manned spaceflight and lunar exploration projects, large spacecraft will become the focus of my country's spaceflight development in the future, and the installation and testing of test instruments and equipment on satellites will be more and larger. , the weight is relatively large, which poses a challenge to the ground assembly, and some instruments and equipment need to be assembled and moved repeatedly. It makes the whole assembly process more complicated, and manpower can no longer complete it. It must rely on the corresponding auxiliary assembly system to proceed safely, reliably and efficiently.

Although the existing turntable can realize product flipping, turning, up and down, left, right, front and back movement, but the up and down movement is manual, and the movement range is small.
