Description
技术领域technical field
本实用新型属于加工机床技术领域,尤其涉及一种双轴复合数控机床。The utility model belongs to the technical field of processing machine tools, in particular to a biaxial composite numerical control machine tool.
背景技术Background technique
当前世界经济和技术发展迅速,随着社会生产力的发展,市场上产品越来越丰富,消费者选择越来越多,对产品的要求也越来越高。提升机器加工效率只能朝着更高的自动化、精度化、速度化这三个方向发展。现有技术的数控机床一般包括底座、X轴运动机构、Y轴运动机构、Z轴运动机构、立柱、横梁、工作台、电主轴和电气控制装置,现有的数控机床主要由主轴和刀具组成,由于数控机床的功能逐渐增多,每一项细小的功能都有相配套的刀具与零配件,因此每一台数控机床的刀具与零配件也越来越多,然而,现在市场上的数控机床存在以下不足:At present, the world economy and technology are developing rapidly. With the development of social productivity, the products on the market are becoming more and more abundant, consumers have more and more choices, and the requirements for products are getting higher and higher. Improving machine processing efficiency can only develop in three directions: higher automation, precision, and speed. The CNC machine tools of the prior art generally include a base, an X-axis motion mechanism, a Y-axis motion mechanism, a Z-axis motion mechanism, a column, a beam, a workbench, an electric spindle and an electric control device. The existing CNC machine tools are mainly composed of a spindle and a cutting tool. , due to the gradual increase in the functions of CNC machine tools, each small function has a matching tool and spare parts, so each CNC machine tool has more and more tools and spare parts. However, the CNC machine tools on the market now There are following deficiencies:
1)现有的数控机床一般只有一个主轴,因此其在使用过程中只能对单个零件进行加工,在进行加工时工作效率低下,加工重复性的工件则要浪费很多资源。此外,遇到要用多把刀加工同一件产品时,现有较为先进数控机床采用常见的自动换刀,即在单个主轴边带一个转盘,转盘里放上若干个刀头,成本非常高,也只能用一个主轴进行加工。1) Existing CNC machine tools generally only have one spindle, so they can only process a single part during use, the work efficiency is low during processing, and a lot of resources are wasted when processing repetitive workpieces. In addition, when the same product needs to be processed with multiple knives, the existing relatively advanced CNC machine tools adopt the common automatic tool change, that is, a turntable is attached to a single spindle, and several cutter heads are placed in the turntable, which is very costly. Also only one spindle can be used for machining.
2)现有的数控机床大部分都是使用斜盘式或者盘式刀库,但现有的数控机床一般使用龙门横梁结构,斜盘式、盘式刀库安装的工艺复杂,且安装位置位于侧面或者主轴正方,这样使得换刀时变得复杂,整体结构尺寸变大,重心偏移使得机身不稳且影响精度,对于生产来说制造成本也比较高。此外,现有的采用排列式刀库的数控机床,一般将排列式刀库固定安装在机床工作台上,减少了工作台的有效使用面积,且由于排列式刀库固定,取刀动作全部由主轴完成,取刀时间长,生产效率低。2) Most of the existing CNC machine tools use swash plate or disc tool magazines, but the existing CNC machine tools generally use the gantry beam structure, the installation process of the swash plate and disc tool magazines is complicated, and the installation position is located at The side or the main shaft is square, which makes the tool change complicated, the overall structure size becomes larger, and the center of gravity shifts make the fuselage unstable and affects the accuracy, and the manufacturing cost is relatively high for production. In addition, the existing CNC machine tools that use arrayed tool magazines generally fix the arrayed tool magazines on the machine tool workbench, which reduces the effective use area of the workbench. The main shaft is completed, the tool takes a long time, and the production efficiency is low.
3)现有的数控机床进行上下料时,一般只能从单侧进行上下料,即,机械手只能从前方或者后方进行动作,导致加工效率大打折扣。3) When loading and unloading the existing CNC machine tools, generally only one side can be used for loading and unloading, that is, the manipulator can only move from the front or the rear, resulting in greatly reduced processing efficiency.
