A precision CNC machine tool that automatically realizes parts turning around to complete their double-sided processing

Abstract

The invention provides a precise numerical control machine tool for automatically realizing turning of a workpiece and finishing double-side processing of the workpiece. The precise numerical control machine tool is provided with a lathe bed, wherein a spindle system is arranged on one side of the upper end of the lathe bed; the spindle system comprises a servo motor, a spindle box and a spindle; a crossing-shaped saddle which slides along a Z direction is arranged on the other side of the upper end of the lathe bed; a supporting plate which slides along an X direction is arranged on the upper end face of the crossing-shaped saddle; a spindle tool rest device is arranged on one side of the upper end of the supporting plate; a rear shaft box, a rear shaft motor and a hollow rear shaft are arranged on the other side of the upper end of the supporting plate; a rear shaft tool rest device is arranged on the end face, opposite to the rear shaft box, of the spindle box; the workpiece is clamped on the spindle and one side of the workpiece is processed by the spindle tool rest device, and then the workpiece is directly assembled on the hollow rear shaft and the other side of the workpiece is processed by the rear shaft tool rest device under the effects of the Z-directional sliding of the crossing-shaped saddle and the X-directional sliding of the supporting plate. The precise numerical control machine tool provided by the invention can realize the detaching and clamping of the workpiece without manual interference; one device is utilized to automatically exchange the side and change the direction of the workpiece and to finish the double-side processing of the workpiece; the processing requirements of low workpiece cost, high efficiency and high precision are met.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tool manufacturing, and in particular relates to a precision numerical control machine tool which can automatically realize parts turning around to complete double-sided processing. Background technique [0002] The CNC machine tool is a high-precision, high-efficiency automatic machine tool. When the existing CNC machine tool processes the workpiece, it can only process one side of the workpiece at a time. Only by re-clamping can the other side be re-processed. Sometimes even two CNC machine tools are required to complete mass production. Machining accuracy, so it is necessary to propose improvements. Contents of the invention [0003] The technical problem solved by the present invention is to provide a precision CNC machine tool that can automatically realize the double-sided processing of the parts by turning around. The back shaft system is added to the existing CNC machi...
