Abstract

The invention discloses a device for synchronously detecting coaxiality and perpendicularity of inner and outer rings of a bearing. The device comprises a base, an inner ring fixing mechanism, a supporting mechanism, a probe mechanism and a driving mechanism, the inner ring fixing mechanism is fixed on the base and is used for fixing an inner ring of the bearing; the supporting mechanism is movably arranged on the base and is used for supporting the bearing inner ring; the probe mechanism is movably arranged on the base; the driving mechanism is used for driving the bearing outer ring to rotate; and the inner ring fixing mechanism can be adjusted according to the diameter of the bearing inner ring. The inner ring fixing mechanism, the supporting mechanism, the probe mechanism and the driving mechanism are arranged, the inner ring of the bearing is fixed through the inner ring fixing mechanism, the supporting mechanism is adopted to support the inner ring of the bearing, it is guaranteed that the bearing is located on the horizontal plane, the probe mechanism makes contact with the outer ring of the bearing, the driving mechanism is used for driving the outer ring of the bearing to rotate, and the structure is simple; the device is low in use cost, convenient to operate and high in measurement precision, and the driving mechanism is adopted to drive the bearing outer ring to rotate, so that the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of bearing production, in particular to a synchronous detection device for coaxiality and perpendicularity of inner and outer rings of a bearing. Background technique [0002] With the rapid development of industry, higher requirements are put forward for the dimensional accuracy of bearings. In the detection of bearing machining accuracy, coaxiality is used as a positioning error, also called shaft misalignment error, which has an impact on the performance of the entire rotating shaft system. big impact. When the bearing has shaft misalignment error during operation, it will cause problems such as bearing friction damage, machine vibration and shaft deflection deformation. Therefore, efficient and accurate detection of bearing coaxiality is very important for the operation of mechanical components. [0003] At present, the existing methods for testing the coaxiality of the inner and outer rings of bearings...
