技术领域technical field

本发明属于数控机床设备装配技术领域,具体涉及一种桥式龙门铣床立柱安装调整结构及其调整方法。The invention belongs to the technical field of numerical control machine tool equipment assembly, and in particular relates to a column installation and adjustment structure of a bridge type gantry milling machine and an adjustment method thereof.

背景技术Background technique

桥式龙门铣床是针对汽车工业中精密模具高速高精加工的设备,其结构特点是工作台静止、横梁沿立柱上的直线导轨在水平方向上移动。立柱作为桥式龙门铣床中重要的支撑部件,其安装与调整对机床的整体稳定性和加工精度有着重要的影响。为了达到国家标准(GB50271-98)中对机床立柱的直线导轨安装面与工作台面的平行度、两立柱之间的平行度以及水平高度一致性的装配要求,通常是经过粗刮、半精刮、整机精度调整时的精密刮研等多道工序,或者通过钢垫块及斜垫片调整直线导轨安装面的水平等方法进行立柱的安装调整。这些方法容易受到刀库重量、立柱材质、应力变形等因素的变化的影响,调整难度大,装配精度与效率低,严重影响机床整机的加工精度与运行性能。The bridge-type gantry milling machine is a high-speed and high-precision machining equipment for precision molds in the automotive industry. Its structural features are that the workbench is stationary and the beam moves horizontally along the linear guide rail on the column. The column is an important supporting component in the bridge type gantry milling machine, and its installation and adjustment have an important impact on the overall stability and machining accuracy of the machine tool. In order to meet the assembly requirements of the national standard (GB50271-98) on the parallelism between the linear guide rail installation surface of the machine tool column and the work table, the parallelism between the two columns and the consistency of the horizontal height, it is usually after rough scraping and semi-fine scraping. , Multiple processes such as precision scraping and grinding during the precision adjustment of the whole machine, or the installation and adjustment of the column by adjusting the level of the linear guide rail installation surface through steel pads and inclined gaskets. These methods are easily affected by changes in the weight of the tool magazine, the material of the column, stress and deformation, etc., the adjustment is difficult, the assembly accuracy and efficiency are low, and the machining accuracy and operating performance of the machine tool are seriously affected.

专利CN103846680B公开了一种铣床立柱调节装置,利用底座上的定位凸边与立柱上的定位凹槽相互配合卡接,并通过螺栓将立柱连接在底座的侧面上,保证立柱与底座的垂直度;专利CN104097070A公开了一种镗床立柱的垂直调节装置,通过立柱座上设有水平测量器,来调节螺柱插入管体的距离,以使立柱座达到水平位置,从而达到调节立柱的垂直度的目的。上述专利中的调节装置只考虑调整立柱与底座的垂直度,未提及立柱直线导轨安装面与工作台面的平行度以及两立柱之间的平行度的调整;且由于调节装置采用螺纹连接,却没有考虑到加工过程中机床振动而导致螺纹连接松动的情况。随着机床使用时间的延长,将会影响到立柱调整的效果。此外,对于专利CN103846680B中的立柱调节装置,一旦出现因连接松动出现立柱倾斜、偏移等现象时,调整非常困难,必须将相关零件全部拆除后才能调整,十分麻烦。Patent CN103846680B discloses a column adjustment device for milling machines. The positioning flange on the base and the positioning groove on the column are used to cooperate with each other, and the column is connected to the side of the base by bolts to ensure the verticality of the column and the base; Patent CN104097070A discloses a vertical adjustment device for a column of a boring machine. A level measuring device is provided on the column base to adjust the distance of the stud inserted into the pipe body, so that the column base reaches a horizontal position, thereby achieving the purpose of adjusting the verticality of the column . The adjusting device in the above-mentioned patent only considers adjusting the verticality between the column and the base, and does not mention the parallelism between the mounting surface of the column linear guide rail and the worktable and the adjustment of the parallelism between the two columns; It does not take into account the loosening of threaded connections caused by machine vibration during machining. With the prolongation of the use time of the machine tool, the effect of column adjustment will be affected. In addition, for the column adjustment device in the patent CN103846680B, once the column is tilted or shifted due to loose connection, the adjustment is very difficult, and all relevant parts must be removed before adjustment, which is very troublesome.
