Description

Technical Field

[0001] The present invention relates to the technical field of finished product detection, and in particular to a surface defect detection device for a mechanically processed finished product. Background Art

[0002] Pipe inner surface inspection technology is an important quality control method in the industrial field, especially in manufacturing, chemical, oil and gas, aerospace and other industries. The quality of the pipeline system is directly related to the safety and operation efficiency of the equipment. There may be various defects on the inner surface of the pipe, such as corrosion, scratches, cracks, sediments, welding defects, etc. These defects will affect the fluid delivery capacity, durability and safety of the pipeline. Therefore, the research and application of pipe inner surface inspection technology has become crucial.

[0003] In the document (publication number: CN116626066B), a surface defect detection device and method for mechanical finished products are disclosed. The device transports the finished product that needs to be inspected for surface defects to a predetermined position through a conveying device, and clamps and limits the inner and outer surfaces of the finished product in sequence through a clamping and limiting device. After the clamping and fixing is completed, the outer and inner surfaces of the finished product are sequentially inspected by a detection device, and the defect detection of the inner and outer surfaces of the annular finished product is completed, which improves the efficiency of the detection process and shortens the detection time. The scheme can improve the clamping efficiency of the surface of the finished product, shorten the surface defect detection time, and improve the detection efficiency; at the same time, it can also flexibly protect the surface of the finished product to ensure the quality of the finished product. However, when inspecting a workpiece with a bend inside, the device cannot meet the requirements of inspecting its curved surface, which will cause the device to have limitations, cannot reasonably meet different detection requirements, and cannot avoid the influence of external light sources on the detection results during actual use, which reduces the accuracy of the device's detection.

[0022] When inspecting a tubular workpiece, its outer surface is usually inspected by rotating the workpiece. Since some tubular workpieces have curved parts, it is difficult to effectively inspect the curved parts when inspecting the inner surface. When inspecting the inner surface, external light sources will also affect the normal inspection. When inspecting the inner surface of a tubular workpiece, first, the workpiece is transferred to the upper surface of the inspection platform 2 by the feeding belt 11, and the electric telescopic rod 25 is started.

As the adjusting rope 56 gradually shrinks, the groups of adjusting tubes 59 gradually return to their original positions, so that the groups of adjusting tubes 59 are mutually engaged, so that the detection mechanism 3 and other components are in the same horizontal plane, thereby completing the detection of the inner surface of the workpiece.
