Description

Technical Field

[0001] The utility model relates to the field of bearing rotation accuracy detection, in particular to a linear bearing rotation accuracy detection device. Background Art

[0002] Linear bearings are a more common type of bearing among existing bearings. This type of bearing has a longer axial length and higher requirements for rotational accuracy. Linear bearings usually need to undergo rotational accuracy testing before being applied to equipment. However, large linear bearings are inconvenient to test due to their large size and long axial length, and the test data at different positions are prone to deviations. The existing linear bearing rotation accuracy detection device fixes the linear bearing on a base, and then sets multiple measuring instruments along the length direction of the linear bearing to measure the rotational accuracy of different positions of the linear bearing. During the test, one end of the measuring instrument needs to contact the outer peripheral wall of the linear bearing. Technical personnel in this field rotate the linear bearing so that the measuring instrument can collect data related to the rotational accuracy. When the linear bearing rotates, the position of the instrument seat used to fix the measuring instrument is easily affected by the rotation of the bearing and changes, and the data measured on different horizontal lines are not easy to form effective test data. The existing measuring device cannot keep multiple measuring instruments on the same horizontal line for measurement, which is likely to affect the measurement data. Utility Model Content
