Counterweight hanging device

Abstract

A counterweight hanging device disclosed by the present invention comprises a counterweight set comprising a plurality of counterweights, a hanging rod and a connecting rod, wherein the middle part of each counterweight is equipped with an axial chamber, an upper circular truncated cone chamber is arranged at the upper part of the axial chamber of the uppermost counterweight, and the lower circular truncated cone chambers are arranged at the lower parts of the axial chambers of the counterweights; the bottom of the hanging rod penetrates the axial chamber of the uppermost counterweight movably, and the bottom of the hanging rod is equipped with a hanging rod circular truncated cone limiting member; the top of the connecting rod is equipped with a connecting rod circular truncated cone limiting member and penetrates the lower circular truncated cone chamber of the upper counterweight movably, and the bottom of the connecting rod is arranged in the axial chamber of the lower counterweight. According to the present invention, the bottom of the above hanging rod is equipped with the hanging rod circular truncated cone limiting member, the top of the connecting rod is equipped with the connecting rod circular truncated cone limiting member, and when the counterweights are loaded, the hanging rod circular truncated cone limiting member can align at the axis of the counterweight set automatically, thereby being convenient to detect. The connecting rod circular truncated cone limiting member can prevent the connecting rod circular truncated cone limiting member and the axial chambers of the counterweights from impacting to influence the detection precision.

Description

Technical field [0001] The invention belongs to the field of mechanical performance detection, and specifically relates to a weight hanging device. Background technique [0002] All measuring instruments must pass metrological verification or calibration to ensure the accuracy and reliability of their measurement data. Corresponding value transmission systems have been established for various measurement parameters in our country. The force measuring instrument is no exception, all of which must be verified or calibrated with a standard dynamometer or a force standard device. [0003] Force value detection is an important part of mechanics measurement and testing, and is widely used in national production and life. Generally, a weight set is used to detect the force value of a product during force value detection. In the prior art, the weight set is formed by connecting multiple weights in series, and the weights are connected by connecting rods. The connecting rod is easy to co...

Problems solved by technology

Generally, weight groups are mostly used to detect the force value of products during force value detection. In the prior art, the weight group is composed of multiple weights connected in series, and the weights are connected by connecting rods. However, ordinary The connecting rod is easy to collide with the inner wall of the weight during measurement, which affects the loading weight and thus affects the accuracy of the measurement
