A dual-axis CNC rotary table driven by inclined axes and dual motors

Abstract

The invention belongs to the field of machine tool accessories, and particularly relates to an inclined shaft dual motor driving double-shaft numerical control rotating table. The inclined shaft dual motor driving double-shaft numerical control rotating table comprises a left inclined shaft assembly, a right inclined shaft assembly, a rotating shaft assembly, and a baseplate. The left inclined shaft assembly and the right inclined shaft assembly are symmetrically arranged on the left side and the right side of the baseplate. The left inclined shaft assembly comprises a left core shaft and a left driving motor, the right inclined shaft assembly comprises a right core shaft and a right driving motor, and the left core shaft and the right core shaft are located on the same axis. In addition, the left core shaft and the right core shaft are driven, under the control of the same driving command, by the left driving motor and the right driving motor correspondingly to rotate synchronously. The rotating shaft assembly comprises a rotating table body and a driving motor which drives the rotating table body to rotate. The rotating shaft assembly is connected with the left core shaft and the right core shaft correspondingly through a left swinging arm and a right swinging arm which are located on the left side and the right side of the rotating shaft assembly. The rotating shaft assembly can swing in a reciprocating mode along with the left core shaft and the right core shaft. The inclined shaft dual motor driving double-shaft numerical control rotating table has the advantages of simple structure, small size, high precision, good machine stiffness, large output torque, and good response characteristics.

Description

technical field [0001] The invention belongs to the field of machine tool accessories, and in particular relates to a cradle symmetrical double-axis numerical control rotary table driven by inclined-axis double motors. Background technique [0002] With the development of science and technology, the rotary functional components controlled by direct drive motors have become the development trend of five-axis CNC machine tools. The CNC rotary table is directly controlled by direct drive motors, which has the advantages of small size, high precision, fast speed, no mechanical wear, No gap, excellent stress state and other advantages. Most of the existing two-axis direct-drive CNC rotary table structures are driven by a direct-drive motor to rotate the swing arm on the fourth axis, and the fifth axis is installed on the swing arm. It is required that the fourth axis must have a good Mechanical rigidity, output torque and response characteristics. However, due to the influence ...

AI Technical Summary

Problems solved by technology

However, affected by the performance of the direct-drive turntable itself, it is difficult to achieve better output characteristics for the fourth axis of the current two-axis direct-drive CNC rotary table, which limits the performance improvement of the CNC rotary table to a certain extent.
