Full-automatic pressure gauge verification table and full-automatic verification method

Abstract

The invention relates to improvement of a pressure gauge verification technology, in particular to a full-automatic pressure gauge verification table and a full-automatic verification method; and thefull-automatic pressure gauge verification table comprises a verification table, a switch, a code scanning device, a camera adjusting mechanism, a camera, a gauge clamping mechanism, a gauge knockingmechanism, a display, a controller and a gas circuit control system; the camera adjusting mechanism comprises a sliding base and a sliding block, the sliding block is in sliding fit with the sliding base, the sliding base is inclined, the camera is installed on the sliding block and faces the gauge clamping mechanism, the gauge knocking mechanism comprises a vertical rod, a telescopic air cylinderand a push rod, the push rod is connected with a telescopic end of the telescopic air cylinder, and a cylinder body of the telescopic air cylinder is installed on the vertical rod. The full-automaticpressure gauge verification table has the advantages of less manual intervention, high automation integration level and high detection accuracy, and can realize the automatic pressure gauge detectionfunction of scanning once, knocking for three times and easily detecting the pressure gauge.

Description

technical field [0001] The invention relates to an improvement to the pressure gauge verification technology, in particular to a pressure gauge automatic verification platform and a full-automatic verification method. Background technique [0002] As the most commonly used instrument among various instruments, pressure gauges need to be judged on the accuracy of their range and pressure measurement after leaving the factory. For the verification of instruments, my country has special verification standards, that is, JJG52-2013 "Elastic Element Type General Pressure Gauge, Pressure Vacuum Gauge and Vacuum Gauge" issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China. In the regulations, it is clear that the zero point error, indication error, return error and slight displacement need to be verified. That is, under the specified environmental conditions, connect the inner cavity of the pressure gauge to the atmo...

Problems solved by technology

It can be understood that although the second generation of products uses image recognition devices to identify the readings of pressure gauges, the main improvement point is that the readings are more accurate, but the workload of manual operations has not been significantly reduced, and for the detection of pressure gauges , due to the large number of tested pressure gauges, for the second-generation pressure gauge verification device, it has not significantly reduced the workload of the measurer for the pressure gauge verification
