Roundness detection device for cylindrical bearing roller

The utility model discloses a roundness detection device for a cylindrical bearing roller, which belongs to the technical field of bearing detection, and comprises a workbench, a circular groove is arranged on the workbench, a rotating device is clamped in the workbench, the rotating device is slidably connected in a clamping device, the rotating device comprises a motor, and the motor is connected with the circular groove. The motor is clamped in the workbench, and a first rotating shaft is fixedly connected to the motor. According to the roundness detection device for the cylindrical bearing roller, the circular groove and the detection device are arranged, a handle is pulled downwards, and four limiting plates drive four sliding blocks to slide towards the periphery in four limiting grooves until the bearing roller to be detected is limited, so that the device can rapidly and effectively limit the bearing roller to be detected, and the detection efficiency is improved. And the condition that the bearing ro
