Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection equipment, in particular to a bearing defect rapid detection device for an industrial robot. Background Art

[0002] Bearings are essential core components in the mechanical manufacturing and machining industries. They are components that fix and reduce the load friction coefficient during mechanical transmission. That is, when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient in power transmission and keep the center position of the shaft fixed.

[0003] Among mechanical products, bearings are high-precision products that require not only theoretical support from numerous disciplines, such as mathematics and physics, but also the expertise of numerous other disciplines, including materials science, heat treatment technology, precision machining and testing techniques, numerical control technology, effective numerical methods, and powerful computer technology. Testing technology is the last line of defense in bearing manufacturing, directly impacting the performance and safety of mechanical transmissions. Therefore, research into testing technology and improving its accuracy are of practical significance.

[0004] There are many different types of bearings, and each requires different inspection emphases. However, generally, these inspections include basic dimensional accuracy testing (inside and outside diameters), component burr detection (smoothness testing), clearance testing, flaw detection, and shape testing (for deformation). The inspection standards for bearings also vary depending on the type of bearing, with some prioritizing smoothness, others focusing on inside and outside diameters, and others requiring rigidity and durability. Therefore, during bearing inspection, different inspection techniques are selected based on the emphasis of the inspection standard.

[0005] At present, the detection efficiency of the bearing detection equipment used is not high, and for high-altitude bearing detection, the detection device needs to be replaced, which makes the detection inconvenient and low in efficiency. Summary of the Invention
