由哈尔科夫组合机床专业设计局设计、哈尔科夫组合机床厂制造的XA—7412型自动组合机床,用于加工阀门壳体类零件(如角形管接头)。该机床的特点是采用料仓型的装料装置,以实现毛坯在工作位置上自动定位以及在装料工位上自动把它放到夹具的夹紧装置内。在此机床上加工零件上的孔及端面。 在圆形床身1的中央(图1)装有八工位分度回转工作台2,在其花盘12上紧固有八个夹具3;工作台由电机通过减速装置带动。在床身上安装有五个自驱式动力头4(ГС05—10型),其中一个卧式安装在垫板
The XA-7412 automatic assembly machine, manufactured by Kharkov Machine Tool Works, is designed by Kharkov Special Machine Tool Design Bureau to process valve housing parts such as angled pipe fittings. The machine features a bin-type charging device to automatically position the blank in the working position and to automatically place it in the clamping device of the fixture at the loading station. In this machine processing parts on the hole and the end surface. The center of the circular bed 1 (FIG. 1) is provided with an eight-position indexing rotary table 2, and eight brushes 3 are fastened on the face plate 12 of the circular bed 1; the table is driven by a motor through a speed reduction device. Five self-propelled power heads 4 (ГС05-10) are mounted on the bed, one of which is mounted horizontally on a backing plate
