Y 3180滚齿机加工齿轮时,由于工作台复位精度不稳定,利用刻度值来控制工件的加工尺寸很难保证,导致工件不合格。为此,我们作了改进。该机床的径向进给(滚切深度)是由工作台滑座下面的丝杠螺母来实现的(附图)。在丝杠6的右端装有一定程油缸,便于工件调整、测量和装拆时快速进退。因此,这就要求螺母支架结构具有较好的刚性。由下半部结构可见,圆锥滚柱轴承4的
Y 3180 gear hobbing machine gear, the table reset accuracy is not stable, the use of scale values to control the processing of the workpiece size is difficult to guarantee, resulting in the workpiece failed. To this end, we made improvements. Radial infeed (hobbing depth) of the machine is achieved with a spindle nut below the table carriage (photo). In the right end of the screw 6 is equipped with a certain length of cylinder, easy to adjust the workpiece, measuring and loading and unloading rapid advance and retreat. Therefore, this requires that the nut support structure has better rigidity. As seen from the lower part of the structure, the tapered roller bearing 4
