镗削多轴头的结构如图1,图2为被加工零件。多轴头的主轴是通过轴向错开啮合的齿轮1驱动的。主轴分为前部2和后部3两部分。前部用滚针轴承支承。承受推力的主轴后部3与前部2用螺纹套环5联接,并可进行轴向微调。刀具用螺纹联接,刀头振摆控制在0.01毫米以内。 Boring multi-axis head structure shown in Figure 1, Figure 2 is processed parts. The spindle of a multi-spindle head is driven by a gear 1 which is offset in the axial direction. Spindle is divided into front 2 and rear 3 two parts. Front with needle bearing support. The thrust-receiving spindle rear part 3 is connected to the front part 2 by means of a threaded collar 5 and allows fine adjustment in the axial direction. Tool with threaded connection, the vibration control head within 0.01 mm.
