T716金刚镗床属专用立式镗床,多用于加工内燃机缸体,主轴不能装刀杆和锥柄刀具,工作台只能纵向移动。由于机床性能的局限性,我们在不损伤机床的原则下,对镗床进行了改装。改装分两步进行,一、在原纵向工作台上增加了一个横向工作台,以满足孔系加工的要求。二、更换原主轴部件。新主轴部件结构见图2。前支承采用双列向心短圆柱滚子轴承15,后支承采用圆锥滚子轴承7,以承受径向力。为承受轴向力,在前支承处还装一单向推力球轴承11。拆下盖1,
T716 King Kong boring machine is a special vertical boring machine, used to process the internal combustion engine cylinder, the spindle can not be installed knife and taper shank tool, the table can only move longitudinally. Due to the limitations of machine tool performance, we modified the boring machine without damaging the machine tool. Modified in two steps, one, in the original vertical workbench added a horizontal table to meet the requirements of the hole system processing. Second, replace the original spindle components. The new spindle components shown in Figure 2. The front bearing adopts double row radial cylindrical roller bearing 15, the rear bearing adopts tapered roller bearing 7 to bear the radial force. In order to withstand the axial force, a one-way thrust ball bearing 11 is also mounted on the front bearing. Remove the cover 1,
