Embodiment 1

[0018] A level meter zero checker, comprising a flat plate 1 and an instrument main body, the instrument main body includes a rectangular base 2, a mandrel 3 and a pressing device; the mandrel 3 is fixed on the rectangular base by the pressing devices at both ends on the seat 2; the main body of the instrument is placed upright on the flat plate 1 by its own weight. The two side surfaces of described rectangular base 2 are two parallel planes and are perpendicular to the bottom surface; The upper and lower ends of the front of described rectangular base 2 are bosses, and a V-shaped groove is provided in the middle of the boss; The center line of the V-shaped groove is perpendicular to the bottom surface of the rectangular base 2, and parallel to the working surface on the back side of the rectangular base 2. The mandrel 3 is a precision cylindrical rod. The mandrel 3 is fixed in the V-shaped groove of the rectangular base 2 through the pressing devices at both ends. The pres...

Abstract

The invention discloses a level gauge zero-position inspection tester. The zero-position inspection tester comprises a flat panel and an instrument body, and the instrument body comprises a rectangular base, a core rod and hold-down devices; the two side faces of the rectangular base are two parallel planes and perpendicular to the bottom face, V-shaped grooves are formed in the upper end and the lower end of the middle of the front face of the rectangular base, the center line of the rectangular base is perpendicular to the bottom face and in parallel with a working face at the back side of the rectangular base, and the two hold-down devices are used for pressing the core rod tightly and fixing the core rod into the V-shaped grooves of the rectangular base. The rectangular base and two core standard components of the core rod form the instrument body in an integrated mode, the instrument body is erected on the flat panel by depending on self weight, rigidity is good, and the zero position of a level gauge can be inspected stably and reliably. By means of the technical scheme, an arc-shaped stand column and a complex fastening device of a traditional old level gauge zero-position inspection tester are omitted, and a core rod is further omitted, so that the level gauge zero-position inspection tester has the advantages of being simple in structure, easy to machine and manufacture, convenient to operate, good in rigidity, stable and reliable in measured data, convenient in instrument periodic verification and the like.

Description

technical field [0001] The invention belongs to the field of measuring standard instruments, and relates to a level meter zero-position checker. Background technique [0002] The traditional old-fashioned level zero checker listed in the current national metrology verification regulations includes a flat plate, an arched column, a parallel square column, two mandrels and a fastening device. The bow-shaped column uses a complex fastening device to fix the parallel square column and a mandrel on the flat plate, and the other mandrel is placed on the two V-shaped blocks on the flat plate. When in use, place the bottom plane and the bottom V-shaped surface of the level to be tested on the flat working surface and the mandrel supported by the two V-shaped blocks respectively, and then attach the side flat working surface and the side V-shaped surface of the level to be tested respectively. The side working surface of the closely parallel square column and the outer circular work...
