Embodiment
The embodiment of the invention provides a kind of implement device of wearability test, be applied to the test of surface imperfection testee, this installs as shown in Figure 3, and comprising: measuring head 301, fixed cell 302, mobile unit 303, pressure regulating unit 304, stationary platform 305, testee 306 and to-and-fro movement number of times are provided with unit 307.Testee 306 is fixed on the stationary platform 305, measuring head 301 is the smooth hard and crisp material (as graphite or pencil-lead etc.) of end face, fixing by fixed cell 302, and contact with testee 306, on the surface of testee 306, doing repeatedly motion (as rectilinear motion etc.) under the control of mobile unit 303, and measuring head 301 contacts well with testee 306 surface test points in the to-and-fro movement process on testee 306; Pressure regulating unit 304 can be adjusted the pressure that measuring head acts on testee 306; The to-and-fro movement number of times is provided with unit 307 and is connected with mobile unit 303, is used for according to manufacturer or user the pressure that acts on testee that the requirement and the pressure regulating unit 304 of testee wearing quality applies being provided with corresponding times of exercise.
Whether also comprise testee wear testing unit in the embodiment of the invention, it is complete to be used to detect testee 306 surfaces of passing through measuring head 301 repeated friction.Testee wear testing unit can be realized by optical technology, promptly passes through the degree of wear on optical reflectance measurements testee 306 surfaces; Certainly, under measuring accuracy is not very high situation,, also can determine whether the testee surface weares and teares by the artificial visually examine in order to save cost.
The embodiment of the invention also provides a kind of abrasion resistance test method, as shown in Figure 4, comprising:
S101 uses the measuring head of the smooth hard and crisp material of end face to contact with testee.Wherein, measuring head comprises graphite or pencil-lead.
S102, measuring head are in testee surface motion preset times repeatedly, and measuring head well contacts with the testee surface in the to-and-fro movement process on testee.Wherein, preset times is according to the requirement of testee wearing quality and the pressure that acts on testee are determined that preset times and pressure are inversely proportional to; In the common test specification, pressure requires to fix, and number of times can suitably be adjusted.
Whether S103 detects the testee surface and is worn, and as not having wearing and tearing, then testee is by test.
Be that example describes with Chinese advanced drawing pencil as measuring head below, as shown in Figure 5 with suitable hardness.
Step s201, the processing pencil make pencil expose the front end pen core, and the front end pen core polishes flat on sand paper.
Step s202 is fixed on pencil in the pencil anchor clamps, the pencil anchor clamps is assemblied in friction and rolling draws on the mobile machine console of lattice machine.
Step s203 installs testing sample on test platform, and this testing sample surface is a lathe tool line shape, and the pencil end face contacts with the testing sample Surface Vertical.
Step s204 applies certain pressure by device for exerting to pencil, and the end face that pencil is contacted with testing sample reaches certain pressure intensity, and this pressure is directly proportional with pressure, is inversely proportional to the pencil face area.
Step s205 perpendicular to the lathe tool line tangent line of sample, makes pencil-lead horizontal linear reciprocating friction sample surfaces, produces the process of a test surfaces abrasion.In the process of friction, because the pencil front end is the plane, and pencil is the hard and crisp material of rigidity, thus can accurately grasp test point, accurate engaged test point, test pressure is accurate, and test result can reflect whole structure.Wherein, can pass through CNC (Computer Numerical Control, computer numerical control) programmed control mobile machine console linear reciprocating motion, drive pencil and do linear reciprocating motion together, surface to be tested rubs.
Step s206, behind the certain number of times of reciprocating friction, the cleaning sample surfaces is assessed the degree that tested surface is worn, if the processing layer on sample surface is galled, illustrates that the wearing quality of this sample is undesirable, if do not galled, then meets the requirements.
The method of testing of the embodiment of the invention, in the process of friction, because the pencil front end is the plane, and pencil is the hard material of rigidity, so can accurately grasp test point, accurate engaged test point, test pressure is accurate, test result can reflect whole structure, thus can assess lathe tool line electroplated structural technology exactly, and the anti-wear performance of other lathe tool line structural manufacturing process.Can be when there be the mobile phone process of this technology in user's use, the anti-wear performance of this technology reaches requirement, increases the satisfaction that the user uses.
More than disclosed only be several specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
