Axle dynamic balancing machine with TTD

The utility model provides a dynamic balancing machine with a TTD axle. The dynamic balancing machine comprises a workpiece clamp seat, a rotary driving motor, a long spline driving shaft, a pair of butt joint shafts, a pair of transmission assemblies, a pair of butt joint action cylinders, a pair of clamping mechanisms, a laser distance measuring sensor, a drilling mechanism, a rotary encoder and a coloring pen. According to the scheme, the output shaft of the axle is adopted for driving, and the rotation frequency of the output shaft is different from that of the input shaft, so that unbalance calculation of the input shaft of the axle and the flange is not affected, and the measurement accuracy is improved; an existing input shaft driving scheme is high in design requirement for an input shaft adapter, the input shaft adapter needs to be tightly positioned and matched with an axle matching surface, and the scheme can avoid the design and manufacturing difficulty. 本实用新型提供一种带TTD车桥动平衡机，其包括工件夹具座、旋转驱动电机、长花键驱动轴、
