Device for measuring raised amount of inner diameter of bearing

The application discloses a device for measuring the raised amount of the inner diameter of a bearing. The device comprises a measurement assembly, an angular table and a lever comparator, wherein themeasurement assembly comprises a measuring head arranged along the horizontal direction, and a measuring rod; the measuring head is installed at the tail end of the measuring rod; a V-shaped groove used for supporting the bearing to be detected is formed in the top of the angular table in a sinking way; the angular table can drive the bearing to be detected to approach the measuring head and enables the measuring head to enter an inner hole of the bearing to be detected; the lever comparator is connected with the measuring head. The novel measuring device is short in detection beats, convenient to operate, accurate in measuring results and low in price. The device can be used for a production field, replaces the traditional contourgraph to detect the raised amount, lowers the detection cost, and increases the det
