Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, and more specifically, to an integrated device for workpiece deburring and wear resistance testing. Background Art

[0002] In the aerospace, instrumentation, medical manufacturing, defense and marine industries, key structural parts that require high surface quality and good wear resistance are increasingly used, and higher requirements are placed on the accuracy and efficiency of the processing methods of such parts. For example, propeller shafts, water-lubricated bearings, dynamic seals, hard-sealed valves, gear transmission parts, and medical cobalt-chromium alloy medical devices are currently processed by electrochemical processing, thermal processing, and ultrasonic vibration processing. However, these processing methods are difficult to guarantee the quality of burr removal and are prone to new damage to the surface state of the workpiece. The friction damage caused by burrs on the surface of related parts during operation is a bottleneck problem that affects the stable, efficient, and long-life operation of equipment;

[0003] At present, the burrs of this type of workpiece are mainly removed by manual grinding. However, grinding tools are difficult to cooperate with workpieces with complex shapes. Surface over-grinding is very likely to occur during the burr removal process. Differences in manual skill levels make it difficult to ensure the quality of burr removal. In addition, it is difficult to test the wear resistance of the workpiece surface after burr removal in the first place. It is difficult to determine whether the wear resistance requirements of the workpiece can be met after burr removal. The surface quality inspection and adjustment of the grinding process have a long cycle, low operating efficiency, and a poor environment. Therefore, improvements are urgently needed.
