Problems solved by technology

Most of the existing CNC lathes use single-spindle machine tools, and their structures include: spindle box, spindle and driving device. When processing workpieces, manual loading, unloading and U-turn clamping are performed by personnel, and the processing efficiency is low.
Repeated positioning of the workpiece leads to large cumulative errors, resulting in poor machining accuracy of the workpiece; and manual clamping poses safety hazards

Abstract

The invention relates to a numerically-controlled machine tool provided with double moving spindles. The numerically-controlled machine tool comprises a base and a tool body, wherein a spindle box and an auxiliary spindle box which are oppositely arranged are arranged on two sides of the base; a spindle is arranged on the spindle box; an auxiliary spindle is arranged on the auxiliary spindle box; the spindle box can move in the axial direction and the radial direction of the spindle on the tool body; the auxiliary spindle box can move in the axial direction and the radial direction of the auxiliary spindle on the tool body. The machine tool provided with the double spindles is adopted, the spindle box and the auxiliary spindle box which are oppositely arranged are arranged at two ends of the base, an auxiliary device or manual turning for clamping is not required, working time consumed for clamping is shortened in the aspect, and the working efficiency is improved; meanwhile, error accumulation caused by repeated clamping is eliminated, and the machining accuracy is improved; besides, both the spindle box and the auxiliary spindle box can move freely in the axial direction and the radial direction, the time for moving between the spindles is shortened, and the machining efficiency is further improved. The machine tool is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of lathes, in particular to a double-moving spindle numerical control machine tool. Background technique [0002] Compared with traditional machine tools, CNC machine tools have the following characteristics. It has the advantages of high flexibility, high processing precision, stable and reliable processing quality, high productivity, improved working conditions, and modernized production management. Most of the existing CNC lathes use single-spindle machine tools, and their structures include: a spindle box, a spindle, and a driving device. When processing workpieces, manual loading, unloading, and U-turn clamping are performed by personnel, and the processing efficiency is low. Repeated positioning of the workpiece leads to large cumulative errors, resulting in poor machining accuracy of the workpiece; and manual clamping poses safety hazards. Contents of the invention [0003] In view of the present ...
