An Automatic Loading System for Weighing Apparatus Type Evaluation

Abstract

The invention belongs to the weighing instrument measurement field, and relates to a loading system used in the weighing instrument type evaluation system, in particular to an automatic loading system used in the weighing instrument type evaluation of 300-3000kg. The system includes a driving mechanism, a loading mechanism and a loading support structure; the system also includes a load transmission part, and the driving mechanism is connected with the loading mechanism through the load transmission part; the present invention provides a The system can be loaded automatically in the thermostat, and the electric drive device of the system is placed outside the thermostat, which prolongs the service life of the mechanism. At the same time, the automatic loading process reduces the impact of human factors on the test environment. The invention realizes the automatic combination of different loads for different weight loading plates, and realizes non-impact loading because a limit mechanism is also set in the system.

Description

technical field [0001] The invention belongs to the weighing instrument measurement field, and relates to a loading system used in the weighing instrument type evaluation system, in particular to an automatic loading system used in the weighing instrument type evaluation of 300-3000kg. Background technique [0002] In the field of metrology, it is aimed at various types of weighing instruments, whether they are mechanical weighing instruments, electronic weighing instruments, or weighing instruments that have been supplemented or modified due to additional requirements for special purposes, or weighing instruments designed due to special technologies. Specifications need to be calibrated and measured to meet the requirements of specified weighing instruments. In the evaluation experiment of weighing instruments, the external conditions such as temperature and humidity should meet the experimental requirements. For the type evaluation experiment of 300-3000kg weighing appara...

AI Technical Summary

Problems solved by technology

For the type evaluation experiment of 300-3000kg weighing apparatus, in the existing technology, the whole machine can only be carried out at room temperature, and the electric hoist is used to lift the weight, and the manual operation is labor-intensive. Due to the participation of personnel, the measurement environment is disturbed. Affected measurement accuracy

[0003] In the prior art, in order to simulate the scale type experiment under the condition of temperature and humidity, it needs to be carried out in the incubator. Under the existing conditions, only the module experiment can be carried out, and the whole machine experiment cannot be carried out.

Due to the impact of artificial loading on the accuracy

[0004] At the same time, if the automatic whole machine loading of the incubator is realized, since the automatic loading system is located inside the incubator, the driving components such as the electrical mechanism are in the incubator, and the components are easily damaged in a warm and humid environment, causing the automatic loading system to not work normally.
