Rack structure of force standard machine

Abstract

The invention provides a rack structure of a force standard machine, comprising an upper beam and a base, wherein the bottom surface of the upper beam and the upper surface of the base are correspondingly and respectively provided with a positioning hole; the rack structure further comprises two pairs of concave-shaped frameworks which are oppositely arranged pairwise; each concave-shaped framework comprises two protruding parts; the upper beam is of a reversed T shape and the base is of a T shape; one protruding part of each concave-shaped framework is clamped with a transverse edge of the upper beam; the other protruding part of the concave-shaped framework is clamped with the transverse edge of the base; the lateral edges of the transverse edges of the upper beam and the base are clung to the inner edges of the concave-shaped frameworks, and the lateral edges of vertical edges of the upper beam and the base are clung to the top ends of the protruding parts; and the length value of the vertical edge of the base is equal to the width value of the top end of each protruding part. The rack structure of the force standard machine, disclosed by the invention, has the advantages of good stability and bearing capability, simple structure, small difficulty of a machining technology and low production cost.

Description

【Technical field】 [0001] The invention relates to a force standard machine structure, in particular to a frame structure of the force standard machine. 【Background technique】 [0002] The force value is an indispensable and important physical quantity in industrial and agricultural production, national defense construction and scientific research. The capacity of the force standard machine and the level of measurement performance are important factors that reflect a country's strategic competitiveness in the fields of industry, national defense and scientific research. sign. At present, the largest force standard machine in China has a measuring range of 30MN. With the development of domestic industrial production and science and technology, there is an increasing demand for the measurement of large force values. Therefore, it is necessary to establish a larger force value base standard to meet the needs of the national aerospace industry, To meet the needs of the developme...

AI Technical Summary

Problems solved by technology

If a four-column structure is used as a force standard machine frame with a large force value, the nuts used to lock the columns are easy to loosen, resulting in poor parallelism of the frame, so there is a problem of difficulty in locking the columns and high locking costs
