Bearing outer ring end face measuring device

The utility model relates to the technical field of bearing measurement, in particular to a bearing outer ring end face measuring device. The device comprises a support, a measuring head assembly, a slide rail assembly and a displacement sensor. The sliding rail assembly and the displacement sensor are arranged on the support, the measuring head assembly is arranged at the lower end of the sliding rail assembly, the contact plate is arranged above the sliding rail assembly, and the sliding rail assembly can drive the measuring head assembly and the contact plate to move up and down. The contact plate is in contact with a contact of the displacement sensor; the lower end of the measuring head assembly is provided with a measuring surface, and the measuring surface can be driven by the slide rail assembly to tightly press the outer ring end face of the measured bearing. According to the device, the measuring surface and the outer ring end surface of the measured bearing form a face-to-face contact form, so that
