Principle: this utility model utilizes screw rod mechanism motion to produce continuous dislocation principle, combined standard specification, material power
The relevant speciality theoretical knowledgies such as, Precision Machinery Design, detection technique, design and manufactured range and cover 10～500mm,
Gauge precision meets the ± cover to reinforcement of 0.2mm, slab thickness measuring instrument calibrating installation, by the assembling of device,
Repeatability, stability checking, analysis on Uncertainty, measurement comparison and characteristic analysis, this device expanded uncertainty isU=
0.7mmk=2 requirements meeting transmission of quantity value, it is possible to carry out magnitude tracing.And be experimentally confirmed, use new reinforcing steel bar protection
Layer, slab thickness measuring instrument calibrating installation compare conventional apparatus at data accuracy, data accuracy, operating efficiency, data can
Tonality and operability are all greatly improved than traditional calibration steps.The many factors affecting thickness measure is also entered by project
Go the analysis of system, good directive function has been played in protective layer thickness measurement from now on.
Conventional steel tendon protective layer thickness measuring instrument calibrating installation uses the standard of all-in-one-piece calibrated bolck or separate type
Block, all can only measure the protective layer thickness of fixed dimension.For different bar diameters, different protective layer thickness need more
Changing different calibrated bolcks, then remeasure protective layer thickness value, practical operation is got up inconvenience, it is impossible to meet what enterprise specified
The measurement of calibration point.
Therefore it is contemplated that the calibrated bolck of standard thickness to be placed directly on reinforcing bar the school carrying out protective layer thickness measuring instrument
Standard, is so on the one hand flatness and the phase that the depth of parallelism of the work surface of calibrated bolck with reinforcing bar axis can be included in work surface
The depth of parallelism to work surface, reduces the partial uncertainty introduced by the depth of parallelism on calibrated bolck surface with reinforcing bar, on the other hand, is
When standard block size is traced to the source, only by the dimensional discrepancy of consideration calibrated bolck, slide calliper rule are used just can the size of calibrated bolck to be traced back
Source.
We utilize screw thread pair to convert rotational motion to the principle that moves along a straight line, and fully take into account during Design and Machining
The factors such as cost, material, hysterisis error, friction, Precision Machining goes out to meet the screw rod that device design requires, non magnetic bottom cooperation
Bearing and the handle at top, strengthen regulation operability；Upper, middle and lower workbench and four column guide rails ensure that device
Stability and degree of freedom, by controlling column guide rail and workbench gap value in addition lubricating oil, it is ensured that workbench moves up and down
The depth of parallelism and stationarity.During assembling, have found that it is likely that in time the perturbing of existence, deform, the problem such as gap value, by transformation,
The amendment mode such as parameter, verification experimental verification, it is ensured that the precision of device, sensitivity and stability.This device is compared tradition reinforcing bar and is protected
Sheath, slab thickness instrument calibrating installation, advantage is to utilize screw lifting mechanism, converts rotational motion into linear motion, can
To provide stable displacement of the lines, and by the Precision Machining to screw pitch, workbench can be improved in lifting process
The precision that displacement controls.
Through actually used inspection, demonstrate this calibrating installation and there is following function and feature:
1. by adjusting screw rod, can quickly and conveniently control instrument, can produce in the range of (10～100) mm and appoint
What size criteria thickness, can meet the requirement of any calibration point of user, and overall range can arrive 500mm, the thickness error of indication
Meet≤± 0.2mm.
The most whole instrument simple, intuitive, easily uses；The indicating value of instrument is stable, good operation performance.
The most whole table apparatus uses nonmagnetic substance.
Through the thickness of protection tier measuring instrument to use different model, variety classes stationary installation (traditional) carried out
Test, test and the use to device, interpretation of result is as follows:
1. from the point of view of data accuracy, adjustable device (this utility model) and the measurement number of stationary installation (traditional)
According to all keeping concordance, maximum error is less than 1mm, and less than code requirement, data of the present utility model are closer to very
Real-valued；
2., from the point of view of data discrete, use the data discrete type of adjustable device (this utility model) than fixed dress
Putting the little of (traditional), adjustable device (this utility model) error of indication more concentrates near null value, and stationary installation
(traditional) data are relatively decentralized；
3., from the point of view of operating efficiency, the operating time of adjustable device (this utility model) is than stationary installation (traditional)
Shorten many, major part shortened to present 20 minute from original 30 minutes；
4. from the point of view of device adjustability, adjustable device (this utility model) one-tenth-value thickness 1/10 can according to client need adjust
Whole to the position of arbitrfary point in (10～100) mm range, and stationary installation (traditional) can only be measured at fixing point；
5. from the point of view of the operability of device, this utility model in terms of reading or size Control all than conventional apparatus
More directly perceived, operation of being more convenient for.
