Abstract
The utility model discloses a two to force measuring device for scratch test instrument, mainly by including: sensor (2), minitype weighing sensor (3), balance pull rod (4) are pressed to sensor connecting block (1), miniature drawing. Install in sensor connecting block (1) minitype weighing sensor (3). Through the miniature screw thread of pressing sensor (2) the left and right sides that draws, connect sensor connecting block (1) and balance pull rod (4). The utility model discloses a two to force measuring device for scratch test instrument has advantages such as simple structure, be liable to change sensor, economical and practical.
Description
Technical field
The utility model relates to mechanics and material testing apparatus, in particular for scratch test instrument two to force measuring device.
Background technology
At present, some simple portable scratch tester, simple to operate, uses counterweight constant load, it is impossible to changes and scrapes head, it is impossible to uses 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 pattern of observation 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 be construction a kind of for scratch test instrument two to force measuring device, be allowed to the disadvantage mentioned above reducing test apparatus cost and overcoming prior art.Device of the present utility model can:
1, measurement in real time, the power recording on 2 directions, and sensor are easily changed；
2, by more emat sensor, the scratch test under different loading condition and measurement collection demand can be met.
3, it is convenient for changing cut and scrapes head, use various shape, the head of scraping of size to carry out scratch test；
The purpose of this utility model is to be realized by following means:
A kind of for scratch test instrument two to force measuring device, for completing the Real-time Collection scraping a normal force and tangential force data during scratch test.Including: sensor contiguous block the 1st, miniature tension-compression sensor the 2nd, miniature LOAD CELLS the 3rd, balancing pull rod 4；Miniature LOAD CELLS 3 is installed in the sensor contiguous block 1 of tubular profile；One end of miniature tension-compression sensor 2 is coupled with the screwed hole 10 of sensor contiguous block 1 by external screw thread, and the other end of miniature tension-compression sensor 2 couples with balancing pull rod 4 also through external screw thread.
Bottom design at sensor contiguous block 1 has end screwed hole 6, it is simple to installs and difform scrapes head, scrapes the cut test under head scratching to be adapted to material in difformity.
Rectangular cut 7 is had, in order to the installation of miniature load cell signal line connects and changes miniature LOAD CELLS on rear side of described sensor contiguous block 1.
Rectangular cut 7 is had, in order to the installation of miniature load cell signal line connects and changes miniature LOAD CELLS on rear side of described sensor contiguous block 1.
Sensor contiguous block 1 left and right sides is both provided with screwed hole, in order to select according to demand to install miniature tension-compression sensor.
The utility model for scratch test instrument two to force measuring device, the scratch test demand meeting different load is different with measurement scope, simultaneously reduction test apparatus cost.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 is adjusted.Provide one for scratch test instrument and provide two to force measuring device, there is simple in construction, be easily changed sensor, economical and practical advantage.
Brief description is as follows:
Fig. 1 is general structure of the present utility model assembling schematic diagram.
Fig. 2 is the view of the utility model sensor contiguous block.Including: upward view (Fig. 2 a), front view (Fig. 2 b), rearview (Fig. 2 c) and axonometric drawing (Fig. 2 d).
Fig. 3 is the utility model balancing pull rod view.Including: front view (Fig. 3 a) and right view (Fig. 3 b).
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 overall assembling 3-D view, gives the assembling relationship figure of all parts.It is installed to miniature LOAD CELLS 3 in sensor contiguous block 1.By the screw thread of miniature tension-compression sensor 2 left and right sides, connect sensor contiguous block 1 and balancing pull rod 4.In Fig. 2,5 and 6 are respectively side screwed hole and end screwed hole.The utility model provide a kind of for scratch test instrument two to force measuring device, there is simple in construction, be easily changed sensor, the advantage such as economical and practical.
