Slewing bearing gap measuring device

The invention discloses a slewing bearing gap measuring device. The device comprises a workbench, and supporting legs are fixedly connected to the four corners of the lower surface of the workbench. The upper surface of the workbench is fixedly connected with a first electric push rod. The output end of the first electric push rod is fixedly connected with a clamping block; a baffle is fixedly connected to the upper surface of the workbench. A through hole is formed in the upper surface of the workbench, the hole wall of the through hole is rotationally connected with an inner ring fixing mechanism through a rolling bearing, two symmetrically-distributed supporting rods are fixedly connected to the upper surface of the workbench, a U-shaped troughplate is fixedly connected to the top endsof the supporting rods, and a fixed rod is fixedly connected to the lower surface of the side, away from the supporting rods, of the U-shaped trough plate. According to the slewing bearing gap measuring device, the slewing be
