Numerical control drilling and milling machine with numerical-control multi-axis double working tables

Abstract

The invention discloses a numerical control drilling and milling machine with numerical-control multi-axis double working tables. The drilling and milling machine comprises a numerical control multi-axis box (1), a lathe bed (2), a portal (3), an X-axis unit (4), an AY-axis unit (5), a BY-axis unit (6) and a Z-axis unit (7); the numerical control multi-axis box is arranged on the Z-axis unit, and is provided with a spindle motor and a plurality of telescopic rotating shafts; the telescopic rotating shafts are composed of oil cylinders (14), spline shafts (15), spline gears (17) and transition gears (18); the AY-axis unit (5) is provided with a working table A (51), and the BY-axis unit (6) is provided with a working table B (61); during work, a machine-borne numerical control electrical system carries out control, numerical control homing and numerical control knife output, collecting and changing are achieved, and shutdown is not needed; and due to the technical scheme of alternative work of the working table A and the working table B, drilling and milling machining achieves the aims that the efficiency is improved, the cost is reduced, and the machine is suitable for large-scale batch production.

Description

technical field [0001] The invention relates to a numerically controlled machine tool, specifically referring to a numerically controlled multi-axis device arranged on a vertical Z axis, capable of holding a plurality of different drilling and milling cutting tools at the same time. , drilling, tapping, countersinking continuous processing of a CNC multi-axis dual-table CNC drilling and milling machine. Background technique [0002] Many workpieces or products are provided with a large number of straight holes, stepped holes, threaded holes, platforms and grooves with different sizes, apertures, shapes and specifications, which are usually processed by CNC drilling and milling machines; the CNC drilling and milling machines of the prior art only set There is a single rotating shaft device that holds a cutting tool, referred to as a single-axis device; the single-axis device can only hold one drilling and milling tool for processing at a time. When the cutting tool needs to b...

[0002] Many workpieces or products are provided with a large number of straight holes, stepped holes, threaded holes, platforms and grooves with different sizes, apertures, shapes and specifications, which are usually processed by CNC drilling and milling machines; the CNC drilling and milling machines of the prior art only set There is a single rotating shaft device that holds a cutting tool, referred to as a single-axis device; the single-axis device can only hold one drilling and milling tool for processing at a time. When the cutting tool needs to be replaced during drilling and milling, although the CNC drilling and milling machine is equipped with a CNC cutting tool However, every time the cutting tool is changed, the machine needs to be stopped. After the tool is changed, it is necessary to return to zero and set the tool, and find the target three-dimensional search, so as to continue processing, resulting in low processing efficiency and high processing cost. Such processing is difficult to adapt to large-scale batch workpieces. Drilling and milling production needs, therefore, the existing technology has the problems and deficiencies of low efficiency, high cost, and not suitable for large-scale mass production
