A slow-down device used in weight measurement verification

Abstract

The invention provides a slow-down device for weight measurement and verification, which includes a damping support, a fixed support, a lower connecting plate, an upper connecting plate, a mass comparator, a slow-down baffle, a compression nut, and a universal wheel; The fixed support fixes the upper and lower connecting plates in the device, the universal wheel is installed at one end of the fixed support, the lower connecting plate is sleeved at one end of the fixed supporting, and the compression nut is used to fasten the lower connecting plate. One end of the damping support is installed on the lower connecting plate, and the other end protrudes from the upper cover of the mass comparator; the mass comparator is placed flat on the upper connecting plate, and its four legs are placed in the bearing area of ​​the fixed support; the buffer baffle is installed on the damping The threaded end of the support guide is used to make contact with the weight to be tested. The device of the invention has reasonable structure, is movable, and is easy to operate, and can have a slow-down and vibration-reducing effect on the placement action of weights of 1 ton or more in the measurement verification process, so as to ensure that the mass comparator is not damaged by impact when the weights are placed.

Description

technical field [0001] The invention relates to the technical field of metrology, in particular to a slow-down device for weights with a mass of 1 ton or more in metrological verification. Background technique [0002] Mass is one of the seven basic physical quantities, and weights are a physical measuring tool that reproduces mass values, and are widely used in various departments. The measurement and verification of weights is realized by weighing and comparing the standard weights and the tested weights by measuring instruments, which is directly related to the accuracy and consistency of mass value transmission. In the existing weight verification technology, the loading and unloading of weights with a mass of 1t or more is usually carried out by manual positioning and manual handling, which requires a lot of physical labor for the verification personnel and is inefficient. And there are many uncontrollable factors in the process of placing the weight, so it is easy to ...

In the existing weight verification technology, the loading and unloading of weights with a mass of 1t or more is usually carried out by manual positioning and manual handling, which requires a lot of physical labor for the verification personnel and is inefficient. And there are many uncontrollable factors in the process of placing the weight, so it is easy to have a severe impact when the weight is in contact with the mass comparator. The impact force will cause damage to the sensor part of the mass comparator, and in severe cases will cause the mass comparator to be damaged. scrapping
