Multi-axis numerical control machine tool

Abstract

The invention belongs to the field of numerical control machining, and particularly relates to a multi-axis numerical control machine tool. The multi-axis numerical control machine tool is compact in structure, high in space utilization rate, small in occupied area, low in weight, high in tool changing efficiency and small in linear axis linkage range so as to achieve high-precision and high-efficiency machining of small precise complex products. The multi-axis numerical control machine tool comprises a lathe bed, a stand column, a cross beam, a tool magazine and a cantilever rotary table, wherein the cross beam and the stand column form a gantry structure to be mounted at the rear end of the lathe bed; the tool magazine and the cantilever rotary table are both mounted on the lathe bed; the cantilever rotary table is positioned in front of the cross beam and can move forwards and backwards along the lathe bed; and the tool magazine is arranged below the cross beam and can be pushed out of the cross beam.

Description

technical field [0001] The invention belongs to the field of numerical control machining, in particular to a multi-axis numerical control machine tool. Background technique [0002] There are a number of typical industries in the market, whose product features are small, precise and complex, such as small precision core molds, watch cases, movements, dental implant abutments, precious metal jewelry, etc. These products have a great impact on processing accuracy and surface effects. It requires high processing efficiency and high processing difficulty, and has strict requirements on the footprint and weight of processing equipment. Existing miniaturized processing equipment has problems such as poor rigidity and low processing accuracy, and most of them are mainly three-axis CNC machine tools, which are difficult to achieve high-precision and high-efficiency processing of complex products; although multi-axis CNC machine tools can achieve high precision for complex products. ...

Problems solved by technology

[0002] There are a number of typical industries in the market, whose product features are small, precise and complex, such as small precision core molds, watch cases, movements, dental implant abutments, precious metal jewelry, etc. These products have a great impact on processing accuracy and surface effects. It has high requirements on processing efficiency and processing difficulty, and has strict requirements on the area and weight of processing equipment

Existing miniaturized processing equipment has problems such as poor rigidity and low processing accuracy, and most of them are mainly three-axis CNC machine tools, which are difficult to achieve high-precision and high-efficiency processing of complex products; although multi-axis CNC machine tools can achieve high precision for complex products. Precision machining, but the existing multi-axis CNC machine tools are generally heavy and have problems such as large footprint, low space utilization rate, and inability to go upstairs, which makes it difficult to meet the requirements of the above-mentioned products for the processing equipment footprint and application site; The existing multi-axis processing equipment still has problems such as low tool change efficiency and large linear axis linkage range due to the influence of structural layout, which affects the improvement of processing efficiency.
