Problems solved by technology

[0002] In recent years, with the rapid development of my country's national economy, the requirements for product quality and precision have also continued to rise. At present, the most commonly used CNC three-axis linkage machine tool has been unable to meet the requirements of modern product processing precision and style due to its own structure.
[0003] In the past, due to the transmission mode of gears, belts and other mechanisms, the transmission mechanism not only increases the transmission control error due to the transmission backlash, but also reduces the structural resonance frequency of the entire system. During control, due to the existence of transmission backlash, the response frequency of the control system is severely limited, which makes the motion control prone to oscillation and even control failure

Abstract

The invention discloses a two-shaft linked rotating workbench for a numerical control machine tool. The workbench comprises an inclined shaft seat (1), a main shaft (2), a rotating seat (3) and a rotating shaft (4), wherein a main shaft moment servo motor (5) is arranged on the inclined shaft seat (1) and directly connected with the main shaft (2); an interference scanning coder (6) with the average pitch of 4mu m is arranged on the main shaft (2); a rotating shaft moment servo motor (8) is arranged on the rotating seat (3) and directly connected with the rotating shaft (4); and an interference scanning coder (9) with the average pitch of 4mu m is arranged on the rotating shaft (4). The workbench is directly driven by high-performance moment servo motors, and dynamic and static errors are reduced to a certain extent; and a workpiece is more easily clamped, the workbench has enough rotating angles, repeated clamping can be avoided, an accumulated error generated by repeated clamping is reduced, and machining accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing machine tools, and relates to the technology of a numerical control machining center. More specifically, the invention relates to a two-axis linkage rotary table of a numerical control machine tool.
