The technical scheme is as follows: the utility model discloses a motor front cover rear cover tang concentricity detection frock, including base, bearing space ring, bearing gland, dabber, spring expansion sleeve, centrum, the dabber supports on through the bearing on the base, separate through the bearing space ring between the bearing and keep a determining deviation, the both ends of bearing are sealed fixed through the bearing gland; the upper end of the mandrel is provided with a cone, and the periphery of the side of the cone is provided with a spring expansion sleeve in a matching manner.

Further, the number of the bearings is two, and the two bearings are separated by a bearing spacer ring to keep a certain distance.

Furthermore, two ends of the spring expansion sleeve are provided with tapers, and the other end of the spring expansion sleeve is controlled by a vertebral body gland to expand.

Further, the vertebral body is adjusted by screws.

Further, the vertebral body adopts a pneumatic structure.

Further, the top and the bottom of the tool are fixed through locking screws in a locking mode.

Has the advantages that: the utility model discloses a frock is made simply, and is with low costs, and is light and handy practical, has effectively solved the difficult problem that preceding, back lid tang concentricity of motor detected, detects high-efficient accurate, has ensured the quality problems of lid around the motor.
