Description
Technical field
This utility model belongs to material and mechanics experimental equipment, especially scratch test instrument and scrapes head unit association area.
Background technology
At present, some simple portable scratch tester, simple to operate, use counterweight constant load, it is impossible to change and scrape head, it is impossible to use difformity, the head of scraping of size to carry out scratch test, and do not possess forces associated measurement apparatus.After test, also can only judge material surface scratch resistant performance by the observation pattern of cut, the degree of depth, it is impossible to measure normal force, tangential force during scratch test.And for some expensive scratching instruments, it has good measurement, acquisition system, but expensive because of it so that test apparatus cost is substantially improved.And the measurement system of such scratching instrument, scrape non-exchange, cause restricted application, scratch test DATA REASONING and the collection of some specific load scope can only be carried out.Fancy price and limited range cause this type of scratch tester to have some limitations.
Utility model content
In view of the above-mentioned deficiency of prior art, the purpose of this utility model is that a kind of self-balancing for scratch test instrument is replaceable scrapes head for structure, is allowed to reduce test apparatus cost and overcome the disadvantage mentioned above of prior art.Device of the present utility model can:
1, it is convenient for changing cut and scrapes head, use various shape, the head of scraping of size to carry out scratch test；
2, gravity self-balancing, can eliminate and scrape the impact that normal force during scratch test is measured by nose heave power；
3, the power measured simultaneously, record on 2 directions, and sensor is easily changed；
4, by more emat sensor, the scratch test under different loading condition can be met and measure collection demand.
The purpose of this utility model is to be realized by following means:
A kind of self-balancing for scratch test instrument is replaceable scrapes head, for completing to scrape a normal force and the Real-time Collection of tangential force data during scratch test.Including: sensor contiguous block 1, miniature tension-compression sensor 2, miniature LOAD CELLS 3, balancing pull rod 4, weights 5, cut scrape 7, fixing bar 8；Miniature LOAD CELLS 3 is arranged in the sensor contiguous block 1 of tubular profile；One end of Minitype tension sensor 2 is coupled with the screwed hole 11 of sensor contiguous block 1 by external screw thread；The other end of Minitype tension sensor 2 couples with balancing pull rod 4 also through external screw thread；Cut is scraped 7 and is connected in bottom sensor contiguous block 1；Weights 5 and turn-knob wing nut 6 are nested with the end of thread at balancing pull rod 4.
Sensor contiguous block (1) rear side has rectangular cut (13), in order to installs and connects the holding wire of miniature LOAD CELLS and change miniature LOAD CELLS.
The bottom design of described sensor contiguous block 1 has screwed hole 12, in order to that installs multi-form scrapes head.
In reality is implemented, all critical piece aluminium alloys and rustless steel process, and aluminum alloy surface is carried out oxidation processes, can effectively prevent phenomenon of getting rusty.During installation, first cut is scraped 7 and is fixed on sensor contiguous block 1 by screwed hole 12；Miniature LOAD CELLS 3 is installed in sensor contiguous block 1；By the screw thread of miniature tension-compression sensor 2 left and right sides, sensor contiguous block 1 and balancing pull rod 4 are coupled together, weights 5 is installed on wing nut 6, and by the screw thread of wing nut 6 turn-knob to balancing pull rod 4.Then, screw 9 and nut 10 is used to be installed on balancing pull rod 4 on fixing bar 8.Finally fixing bar 8 is fixed on scratch test instrument by screw 9.Scrape 7 by changing cut, available difform scrape the scratch test that head is carried out.
Self-balancing of the present utility model is replaceable scrapes head, and the scratch test demand meeting different load is different with the scope of measurement, reduces test apparatus cost simultaneously.Owing to scratch tester uses force-feedback control to scrape a normal direction motion, elimination is needed to scrape the impact of nose heave power, so this utility model uses weights and wing nut to balance and scrape head unit gravity.And moved left and right by wing nut so that in the case of being changed without weights, change difformity, size scrape head.Utilize two independent tension-compression sensors, measure normal force and tangential force respectively.By change individually, easily normal direction and tangential on sensor, can to normal direction and tangential on measurement range, precision be adjusted, scrape the advantages such as replaceable, gravity self-balancing, structurally simple, economical practicality.

Detailed description of the invention
Below in conjunction with the accompanying drawings, structure of the present utility model is described in further detail.
Fig. 1, by entirety assembling 3-D view, gives the assembling relationship figure of all parts.First cut is scraped 7 be fixed on sensor contiguous block 1 by screwed hole 12；Miniature LOAD CELLS 3 is installed in sensor contiguous block 1；By the screw thread of miniature tension-compression sensor 2 left and right sides, sensor contiguous block 1 and balancing pull rod 4 are coupled together, weights 5 is installed on wing nut 6, and by the screw thread of wing nut 6 turn-knob to balancing pull rod 4.Then, screw 9 and nut 10 is used to be installed on balancing pull rod 4 on fixing bar 8.Finally fixing bar 8 is fixed on scratch test instrument by screw 9.Scrape 7 by changing cut, available difform scrape the scratch test that head is carried out.
Use structure of the present utility model, be convenient for changing miniature tension-compression sensor 2, miniature LOAD CELLS 3, scratch test demand and the measurement scope of different load can be met；Simultaneously, by balancing pull rod 4, weights 5 and wing nut 6, when can balance scratch test, sensor contiguous block 1, miniature tension-compression sensor 2, miniature LOAD CELLS 3, weights 5, wing nut 6 and cut scrape the gravity of 7, realize self-balancing, thus eliminate this device self gravitation to impact when normal force measurement, collection.
