Multi-axis motion and series manipulator composite drive four-reflector polishing machine tool

Abstract

The invention discloses a multi-axis motion and series manipulator composite drive four-reflector polishing machine tool which comprises an X-direction linear module, a Y-direction linear module, a Z-direction linear module, a B-direction rotating platform assembly, a C-direction rotating platform assembly, a machine tool body assembly, an air cylinder counterweight device and a movable working platform. The X-direction linear module is fixed to a bottom plate of the machine tool body assembly, and the Z-direction linear module is fixed to the X-direction linear module. The C-direction rotating platform assembly is fixed on the Z-direction linear module, the Y-direction linear module is fixed to a stand column of the machine tool body assembly, the movable working platform is fixed to the Y-direction linear module, and the B-direction rotating platform assembly is fixed to the movable working platform. A workpiece clamp device is fixed on the B-direction rotating platform assembly, one end of a series mechanical arm tool is fixed to the C-direction rotating platform assembly, and the other end of the series mechanical arm tool is provided with a polishing tool head which is matched with the workpiece clamp device to polish the optical curved surface of a workpiece.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and specifically relates to a multi-axis motion and serial manipulator compound-driven four-mirror polishing machine tool.
