Free-combination automatic-weight adding device

Abstract

The invention discloses a free-combination automatic-weight adding device, which is used for automatic weight adding in the pressure detection field. The device comprises a group of cylindrical weights (6) arranged in a sleeving mode, and the upper end of each weight layer (6) is provided with a driving mechanism for driving the weight (6) to move up and down; and a weight tray (8) with a weighing or pressure detection mechanism additionally provided is arranged below the weight (6). Heights of the weights (6) are sequentially decreased from inside to outside, a supporting groove (41) is arranged in the exposed column surface of the upper end of each weight, and supporting rods, an inner ring (13), a middle ring (14) and an outer ring (15) are correspondingly arranged. The free-combination automatic-weight adding device is used in the pressure detection or weighing system, free combination and automatic weight adding of the weight adding operation can be realized, the operation is convenient, and weight adding is accurate.

Description

technical field [0001] The invention relates to an automatic weight adding device, in particular to an automatic weight adding device applied in the field of pressure detection, that is, a free combination automatic weight adding device. Background technique [0002] In the field of physical quantity detection, it is often required that the detection system provide a specific force. For example, in the field of pressure detection, various forms of pressure gauges, pressure sensors, and pressure transmitters are commonly used instruments for pressure detection. industrial processes and research fields. The performance of the pressure gauge is directly related to the quality of the test results. In order to ensure the detection accuracy of the instrument, the pressure gauge must be calibrated regularly. Currently, it is common practice for businesses to perform periodic checks and calibrations on all pressure gauges. This requires that the pressure gauge detection and calib...

AI Technical Summary

Problems solved by technology

Weights are generally the benchmark for pressure gauge testing and calibration. It is a common practice for pressure gauge testing to form a specific weight through a specific combination of weights to exert pressure on the pressure gauge. However, at present, the work of adding weights is generally done manually. Repetitive labor, dry work, manual overweighting is difficult to maintain stable pressure, and the pressure fluctuates greatly. The system cannot perform real-time measurement and automatic compensation, which brings errors and other problems to the verification results, and manual operation is easily affected by factors such as ambient temperature, humidity, and atmospheric pressure. influences
