Description
Technical field
The utility model relates to a kind of clamping device of Physico-chemical tests instrument, a particularly lee ' hardness reference block clamping device for simulated field test service condition, or a kind of lee ' hardness test reference block assembly containing this lee ' hardness reference block clamping device.
Background technology
Leeb Hardness Tester is mainly used in on-the-spot hardness and detects fast, and the concrete steps that ball hardness number is measured in current use standard lee ' hardness test block are as follows:
Step 1, choose the standard lee ' hardness test block of a certain fixing hardness number;
Step 2, the test block of standard lee ' hardness to be steadily positioned on horizontal support plane;
Step 3, the vertical survey of use Leeb Hardness Tester obtain numerical value;
Step 4, compare to the hardness number of measured value with standard block of hardness itself, the error within acceptability limit can be accepted;
Step 5, use are carried out calibrated sclerometer and are measured unit under test, obtain corresponding ball hardness number after obtaining lee ' hardness value by certain fixing conversion relation.
This measuring method has following three obvious shortcomings:
1, consider from the angle of accuracy, detected parts should be chosen the standard hardness test block close with detected parts hardness number and demarcate before use Leeb Hardness Tester is measured.But the hardness number alternative of actual Plays hardness test block is less, limitation is large, can not meet the hardness requirement scope of all detected parts completely, usually differ comparatively far away with the hardness number scope needed, the accuracy after in this case checking for sclerometer can produce considerable influence.
2, consider from the convenience measured, due to Richter scale standard hardness test block, because its test block volume and weight is all comparatively large, not portable, therefore on-the-spot test all only has one piece of reference block to demarcate usually, and portability is poor, should not carry.
3, consider from the operability of measuring process, owing to using the process need of standard lee ' hardness test block, test block is placed in the horizontal plane stably, therefore, in calibration process, can only demarcate the measurement accuracy of sclerometer vertical direction, other direction of measurement cannot be carried out.
It can thus be appreciated that, scleroscopic check before using the generation of the error in standard lee ' hardness test block measuring process and measuring, demarcate certain relation.But because accepted standard lee ' hardness test block hardness number is single, scope is limited to, can only checks for a certain durometer level, the durometer level of all detection parts can not be met.When the hardness of detected parts differs larger with standard lee ' hardness test block hardness number, measurement result can not react lee ' hardness value and the ball hardness number of this kind of material reality really, therefore causes measuring error to cause more greatly measurement effect bad.
And current standard lee ' hardness test block can only be checked vertical survey direction or demarcate, but actual measurement often can be measured for the parts of different angles, because direction difference also can bring larger measuring error in measuring process.
