Description

Technical Field

[0001] The utility model relates to the technical field of wheel production, in particular to a hardness testing machine for wheel production. Background Art

[0002] A hardness tester is a device for measuring the hardness of metal materials. It can measure the surface Rockwell hardness value of steel, alloy steel, cemented carbide, electroplating layer, carburizing, nitriding and cyaniding layer. The measured hardness value can be read directly from the display window.

[0003] During the production process of wheels, it is usually necessary to perform hardness testing on the wheel hub to determine whether it meets the factory requirements. However, in the current testing process, since there is no limit fixing structure on the testing table, the wheel hub position is easily offset and shaken during the downward pressure testing of the pressure head, thereby affecting the accuracy of the test. In addition, there is no protective structure on the periphery. When the hardness does not meet the qualified requirements, local fragmentation is easy to cause fragments to splash, posing a major safety hazard. Therefore, in view of the above-mentioned deficiencies, the utility model makes the following improvements. Utility Model Content
