Abstract

The invention discloses a synchronous double-spindle-box numerically controlled lathe. The synchronous double-spindle-box numerically controlled lathe comprises a lathe body and a main motor arranged on one side of the lathe body, wherein a left spindle box and a right spindle box are arranged at the two ends of the lathe body, a synchronous shaft is arranged between the left spindle box and the right spindle box, the lathe body is provided with a lathe saddle, the lathe saddle is provided with a ball screw a, a servo driving motor a is arranged on one side of the lathe saddle, a middle supporting plate is arranged on the lathe saddle, a servo driving motor b is arranged on one side of the middle supporting plate, a ball screw b is arranged in the middle supporting plate, and an electric tool tower is arranged on the middle supporting plate. When the lathe machines a long-axis-class workpiece, the two ends of the workpiece can be clamped and rotate synchronously, multiple times of machining can be carried out on the workpiece through one time of clamping, and production efficiency is improved. Thus, the dimensional accuracy of the workpiece is guaranteed, the automation degree is high, the productivity efficiency is improved by 6-8 times, and the labor cost is largely reduced.

Description

technical field [0001] The invention is a numerically controlled machine tool, more specifically a numerically controlled lathe with synchronous double spindle boxes. Background technique [0002] At present, it is mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces. It is the most widely used type of machine tool in machinery manufacturing and repair factories. Rotary processing machines such as milling machines and drilling machines are derived from lathes. Milling machine refers to a machine tool that mainly uses milling cutters to process various surfaces on workpieces; [0003] When machining long-axis workpieces on CNC machine tools, when processing the end far away from the chuck, the workpiece is too long to easily cause the workpiece to jump during the processing rotation, resulting in the workpiece being unable to be processed at one time, and it is necessary to stop the machine for repeated clamping, which not only delays the ...
