Instrument device for detecting bearing inner diameter runout

Abstract

The invention belongs to the technical field of bearing detection, and particularly relates to an instrument device for detecting bearing inner diameter runout. The instrument device comprises a base,wherein a supporting plate is fixed on the base, and one side of the supporting plate is provided with a structure for fixing a bearing outer ring of a to-be-detected bearing; a supporting plate is fixed to other side of supporting plate, a second air cylinder rotating seat and a third air cylinder rotating seat are installed on the upper portion of the supporting plate, the upper portion of thesecond air cylinder rotating seat is in shaft connection with one end of a second air cylinder, the upper portion of the third air cylinder rotating seat is in shaft connection with a third air cylinder fixing seat which is detachably connected with a third air cylinder, a piston rod of the second cylinder drives the third cylinder and the third cylinder fixing seat to rotate relative to the thirdcylinder rotating seat, and a piston rod of the third cylinder is connected with a measuring meter which can be driven by the third cylinder to the other side of the supporting plate. The device is adetection instrument capable of positioning the bearing in the axial direction by using a cylinder, so that the detection result is more stable and accurate.

Description

technical field [0001] The invention belongs to the technical field of bearing detection, and in particular relates to an instrument device for detecting the runout of the inner diameter of a bearing. Background technique [0002] In the existing technology, when the inner diameter runout of cylindrical roller bearings is tested, when the heavy bearings are tested by the traditional "triangular eccentric platform" detector, the inner and outer rings cannot be concentric by manpower, and there is a slight "dislocation". Measurements that cause inside diameter runout are false and not accurate enough. Contents of the invention [0003] In view of the defects of the prior art, the present invention provides an instrument device for detecting the runout of the inner diameter of the bearing, which is a detection instrument capable of positioning the bearing in the axial direction with a cylinder, which can make the detection result more stable and accurate. [0004] In order t...
