Double-shaft composite numerical control machine tool

Abstract

The invention discloses a double-shaft composite numerical control machine tool. The machine tool comprises a base, a lathe bed is fixedly mounted on the base, a workbench is mounted on the lathe bed,the upper end of the lathe bed is provided with a gantry, two driving mechanisms are slidably mounted on the gantry, spindle mechanisms are mounted on the driving mechanisms, the driving mechanisms can drive the spindle mechanisms to move along an X axis and a Z axis, the spindle mechanisms can also be driven to rotate, a straight-line tool magazine is mounted below the spindle mechanisms, and the straight-line tool magazine is slidably mounted on the gantry. According to the double-shaft composite numerical control machine tool, the two driving mechanisms are arranged, the driving mechanismseach drive one spindle mechanism to move along the gantry and drives the corresponding spindle mechanism to move and rotate along the Z axis, so that the flexibility of movement of the spindle mechanisms is improved, and multi-angle machining can be carried out on a workpiece; and automatic tool changing is achieved through forward stretching of the straight-line tool magazine, the tool magazineretracts into the gantry during standby of the machine tool, so that the occupied space of the tool magazine on the machine tool is reduced, and the machining space of the machine tool is increased.

Description

technical field [0001] The invention relates to the technical field of processing machine tools, in particular to a dual-axis compound numerical control machine tool. Background technique [0002] Existing machine tools are used for multi-process processing of parts, especially when different processes need to process different planes or even in-hole processing, they often need to be processed separately by multiple lathes, milling machines or grinding machines with separate functions. The workpiece is positioned and clamped multiple times, the operation is cumbersome, and it is easy to cause low machining accuracy. [0003] Existing machine tools that respectively clamp workpieces with two spindles and process different processes, drive two spindles to move through a single screw or drive one spindle to move through two coaxial lead screws to clamp and grasp workpieces. Pick. [0004] Machine tools that drive two spindles through a single lead screw often have the disadva...

AI Technical Summary

Problems solved by technology

[0004] Machine tools that drive two spindles through a single lead screw often have the disadvantage of insufficient rigidity of the leads, which affects machining accuracy; while two lead screws set on the same axis drive one spindle to move for processing, the spindle movement The location is limited, which will also affect the use of the machine tool, and the existing machine tool has a single processing angle for the workpiece, and cannot perform complex processing operations on the workpiece
