A wheel hub bearing defect detection device

Abstract

The application belongs to the technical field of bearing detection, and discloses a hub bearing defect detection device, which comprises a bottom support frame, a workbench fixedly connected to the top of the bottom support frame, a fixed clamping table fixedly connected to one side of the top of the workbench, and a movable clamping table arranged on one side of the fixed clamping table. The fixed clamping table and the movable clamping table are both in a strip shape. The fixed clamping table is used for positioning and clamping one end of a hub bearing, and the movable clamping table is used for clamping and fixing the other end of the hub bearing in cooperation with the fixed clamping table. A driving assembly is arranged on the top of the workbench and is used for driving the movable clamping table to displace towards the fixed clamping table, so as to adjust the distance between the movable clamping table and the fixed clamping table. A translation assembly is installed on the top of the workbench. An electric push rod is connected to the translation assembly and is used for providing power in the vertical direction. After the hub bearing is fixed, hardness and surface defect detection can be completed at one time, and the practicability is improved.
