Description

A kind of device of modified test cladding wearability energy

Technical field

The utility model relates to abrasion resistance testing device, is specifically related to a kind of device of modified test cladding wearability energy.

Background technology

Traditional analog watch is worn in process and is caused the test method of wearing and tearing to be: use an industrial rotation buffing machine, the container that artificial organic material is manufactured is installed on it.Tested parts and friction material are put into container and carry out roll cast, the potpourri that friction material forms for the cylindrical or ball-type grinding element being comprised of particles of silicon carbide and the clear water that adds surface tension agent.

First test need to measure watch case and during within 1 year, wearing, be worn the weight of rear loss, after this loss in weight is determined, just can define and obtain the accelerated wear test duration (circulation effective wearing and tearing of corresponding a year) of a circulation.Then with this duration of test runs wearing and tearing calibration pad, by the loss in weight of more accurate packing ring, demarcate the performance of each test friction material used, the mass loss of calibrating pad after an accelerated wear test cyclic test should be 6mg ± 2mg, and to answer service precision be that the precision balance of 0.1mg is measured.Standardized washer material is 316L stainless steel, hardness: 210HV1 ± 10HV1, roughness Ra 0.4um.

The problem that above conventional test methodologies exists is:

1) can not wear the wearing and tearing in process by realistic simulation wrist-watch because wrist-watch in wearing process normally with the material production friction of the hardness such as clothing lower than coating hardness.

2) the more general coating of emery (as gold-plated, plating TiN) hardness exceeds too much, in actual use, finds, for hardness, differs larger coating, amount to into the accelerated wear test required time of a circulation, differ very little, be difficult to distinguish coating wear resistance, possess hardly comparability.

Utility model content

The technical problems to be solved in the utility model be to provide a kind of modified test cladding wearability can device, compact conformation, easy to use, there is the function that retains test data after suspending, be convenient to test and count accurate recording when total.

For achieving the above object, the technical solution of the utility model is as follows:

A device for modified test cladding wearability energy, comprising:

One frame,

One watchcase clamping device,

And some groups of roller set that frame one side is set, webbing forms a closed-loop path around roller set,

The watchcase to be tested of described watchcase clamping device clamping contacts with fabric zone face,

One control system is also set above frame, and described control system comprises a control enclosure, and the timer on control enclosure is set.

Preferably, watchcase clamping device comprises a load bar, and load bar end arranges a table folder frock.

Preferably, on described load bar, a scale label is also set.

Preferably, described watchcase frock is " H " type, and load bar end connects " H " type upper recess, and " H " type lower notch connects a watchcase to be tested.

Preferably, described roller set comprises a loading wheel, a pair of driving wheel and a pair of additional wheel, and described additional wheel arranges frame topmost, loads wheel and frame is set bottom, and driving wheel arranges central rack both sides.

By technique scheme, the beneficial effects of the utility model are:

The utility model is applicable to the various tectal tribological property tests such as electrodeposited coating, vacuum-coating.Obvious to different hardness coating test findings, be easy to distinguish coating wear resistance, there is very high reference value.

Test be take webbing as friction material, applies with constant friction force and arrives testpieces surface, and webbing has good suitability to workpiece geometries, can carry out abrasion resistance properties test to the part of the complicated shapes such as watchcase, watchband.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is structural representation of the present utility model.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

With reference to Fig. 1, a kind of device of modified test cladding wearability energy, comprise: a frame 1, one watchcase clamping device 2, watchcase clamping device 2 is connected with support by a through hole, and the some groups of roller set 3 that frame 1 one sides are set, and webbing 4 forms closed-loop paths around roller set 3, webbing 4 width are equal to or less than the roller mouth of roller set, and the watchcase to be tested 201 of described watchcase clamping device 2 clampings contacts with 4 of webbings.

Watchcase clamping device 2 comprises a load bar 202, and load bar 202 ends arrange a table folder frock 203.

Watchcase frock 203 is " H " type, and load bar 202 ends connect " H " type upper recess, and " H " type lower notch connects a watchcase 201 to be tested.
