Axial positioning device

The axial positioning device comprises a machine body and a transmission shaft arranged in the machine body, the outer side of the transmission shaft is sleeved with a bearing, and when the transmission shaft moves towards the left side, a step on the left side of a stop sleeve achieves thrust on an outer ring of the bearing; and when the transmission shaft moves towards the right side, the bearing outer ring realizes thrust through the adjusting pad and the bearing cover. According to the axial positioning device, reasonable distribution of the axial size of the transmission shaft is achieved through the stop disc, the gear and the transmission shaft are connected through the bolt, and the purpose of power output is achieved; through the innovative design of the stop sleeve and the adjusting pad, the axial positioning problem of the transmission shaft is solved; reliable lubrication of the transmission shaft is achieved through the design of a bushing oil way. 本发明提供了一种轴向定位装置，包括机体及其内部设置的传动轴，传动轴外侧套接轴承，当传动轴向左侧窜
