Technical Field
The invention relates to the technical field of measuring instruments, in particular to a full-automatic resiliometer calibrator.
Background
The rebound tester is used for testing the compression strength of materials such as concrete, mortar, bricks, rock, rubber and the like, and the principle is that a rebound value is obtained by bouncing the surface of a tested object, and the rebound value is used as an index related to the compression strength of the tested object to estimate the compression strength of the tested object. To ensure that the resiliometer has a uniform measurement reference, calibration is required before use.
The rebound apparatus has wide application in the aspect of concrete compression strength and large quantity. The existing calibrator is purely mechanical, depends on manual operation, needs to gradually and sequentially measure various parameters manually, has low efficiency, and cannot meet the requirement of large-scale metering calibration work. Some technical indexes often need artificial sensory judgment, and the accuracy and objective consistency of measured data cannot be completely guaranteed. Moreover, the purely mechanical resiliometer calibrator requires a long learning and experience accumulation of the user, so that the measured data are prone to human error. The existing calibrator is split, the measurement of the rigidity of the spring impact tension spring needs an independent tension spring instrument, the graduation of a scale of the tension spring instrument is 0.5mm in precision, and the precision requirement of the rigidity measurement of the spring impact tension spring cannot be met.
The specifications and models of the resiliometers are many, and the existing purely mechanical type calibrator can only calibrate the M225 type resiliometers, wherein the L20 type resiliometers, the L75 type resiliometers, the H450 type resiliometers and the H550 type resiliometers can not be calibrated. The existing purely mechanical calibrator is manually measured and recorded, detection reports are manually filled in at the later stage, data are not easy to store and store, and some descriptive statements are used for measuring data, such as: the tensile length of the impact tension spring is measured when the impact is not performed, and the judgment of the state is different from person to person. The calibration regulations of the resiliometer still have no corresponding matched machines and tools so far, and cause certain technical obstacles for the popularization and the use of the resiliometer.
