Embodiment Construction

[0017] The embodiment of the present invention provides a device for realizing the wear resistance test, which is applied to the test of objects with irregular surfaces. The device is shown in FIG. An adjustment unit 304 , a fixed platform 305 , a measured object 306 and a reciprocating times setting unit 307 . The measured object 306 is fixed on the fixed platform 305, and the test head 301 is a hard and brittle material (such as graphite or pencil lead, etc.) Under the control of 303, the surface of the measured object 306 is repeatedly moved (such as linear motion, etc.), and the test head 301 is in good contact with the test point on the surface of the measured object 306 during the reciprocating movement on the measured object 306; the pressure adjustment unit 304, the pressure that the test head acts on the measured object 306 can be adjusted; the reciprocating motion times setting unit 307 is connected with the mobile unit 303, and is used to adjust the wear resistance ...

Abstract

The invention discloses a device for test abrasion resistance, used to test the object with irregular surface. The invention comprises a test head, a movable unit and a fixed platform, wherein an object is arranged on the fixed platform, the test head controlled by the movable unit reciprocally moves on the object, the test head is made from rigid and brittle material, the end of the test head is flat, test head has better contact with the surface of the object in the reciprocal movement. The invention also provides a relative abrasion-resistance test method. When in use and in friction, since the end of the pencil is flat and the pencil is rigid, the invention can accurately pickup test point, to contact the test point accurately, therefore, the test pressure is accurate, and the test result can represent whole effect, to accurately evaluate the plated structure art of lathe tool, and the abrasion resistance of structure of other lathe tool.

Description

technical field [0001] The invention relates to the technical field of surface wear testing, in particular to a method and a device for realizing wear resistance testing. Background technique [0002] With the improvement of people's living standards, more and more people use mobile phones, which have become one of the essential items for most people. At the same time, as users have higher and higher requirements for the quality of mobile phones, the competition for the appearance of mobile phones has become more and more fierce. Various appearance and surface structures of mobile phones are also displayed in front of everyone. Wear resistance is a key performance of the reliability and quality of the appearance of mobile phone products. The quality of wear resistance directly affects the appearance life of the mobile phone and the user's satisfaction with the mobile phone. Therefore, when the mobile phone leaves the factory, it is necessary to conduct a wear resistance tes...
