The utility model discloses a positioning and rotation driving mechanism for ultrasonic automatic detection of a valve conical surface, which is characterized by comprising a motor, a pneumatic centering chuck and a clamping jaw, the pneumatic centering chuck is coaxially connected with a motor shaft of the motor and is driven by the motor to rotate; the clamping jaw is arranged on the pneumatic centering chuck and is used for clamping a valve rod part of a tested valve; the clamped length of the valve rod part is not smaller than one fifth of the total length of the valve rod part and not larger than one half of the total length of the valve rod part. The positioning and rotation driving mechanism solves the problems of rotation slipping and stall in the air valve detection process; and the adjustment workload required during model changing of the tested valve is reduced. 本实用新型公开一种用于气门锥面超声自动化检测的定位及旋转驱动机构，其特征在于，包括：电机、气动定心卡盘以及夹爪；气动定心卡盘与电机的电机轴同轴连接且由电机驱动旋转；夹爪安装在气动定心卡盘上，夹爪用于夹持被测气门的气门杆部；气门杆部的被夹持长度不小于气门杆部总长度的五分之一且不
