Problems solved by technology

However, when the structural dimensions of the components that need to rotate coaxially are relatively large, the use of the above-mentioned traditional structural forms will inevitably cause the designed turntable body to be too large in the axial direction, thereby restricting its use.

Abstract

The invention provides a multi-layer nested parallel type coaxial rotary structure. Multiple rotary bodies used for achieving driving, electrical connection and position calculation are nested together to form a parallel structure, coaxial movement of the multiple rotary bodies can be guaranteed, and the structural size of the coaxial rotary bodies can be minimized. A shell, a main shaft and more than two coaxial rotary components are included. The main shaft is supported in the shell through a bearing; more than two annular cavities coaxial with the main shaft are arranged between the shell and the main shaft along the radial direction, and the annular cavities correspond to the coaxial rotary components one by one and are respectively used for mounting the coaxial rotary components; and a rotating part of each coaxial rotary component is fixedly connected with the main shaft and rotates along with the main shaft, and a fixed part of the coaxial rotary component is fixedly connected with the shell.

Description

Technical field [0001] The present invention relates to a rotational structure, and more particularly to a coaxial rotary structure, which belongs to the multi-component coaxial rotation high precision turning table. Background technique [0002] Typically, when the multi-component co-axis is required, it is usually implemented in series through the coaxial series of each rotating body. However, when the components of the common shaft rotation are required, the above-mentioned conventional structural form will inevitably cause the design of the turntable to be excessive axial dimension, thereby limiting it. [0003] Based on this, it is necessary to design a turntable structure that can minimize axial structural dimensions while achieving multi-component coaxial rotation. Inventive content [0004] In view of this, the present invention proposes a multi-layer nested parallel coaxial swivel structure, not only to the multi-return coaxial movement, but also minimizes the structura...
