The end face of the motor shell or the pump shell of the integral structure needs to form a friction pair with parts such as rotor blades, gear shafts or cylinder bodies, and the like, so that the integral structure has high requirements on flatness and roughness. After the end face and the step face are machined in one-time clamping, finish machining such as grinding is needed. When the end face is ground and the like, the parallel precision relative to the step face needs to be controlled, otherwise, the running-in state and the service life of a hydraulic motor or a hydraulic pump are influenced. In the existing detection method, the parallelism error is usually measured by a depth micrometer at multiple points, the detection efficiency is low, and improvement is needed.
