Description

Gravity direction analyzer
Technical field
The present invention relates to gravity direction analyzer, especially for the gravity direction analyzer of measurement support weight.
Background technology
During support Design is claimed, in order to simplify the stress of beam, make its pulling force or pressure by a direction, to knot The force direction that bears of structure beam is demarcated, and the beam of support weight is not produced the power such as moment of flexure and shearing in other directions, and is influenceed The weighing precision of weighing sensor, therefore the perpendicularity of the beam is demarcated first.
The content of the invention
The invention provides gravity direction analyzer, and the beam perpendicularity for supporting weight is demarcated, preferably solves it The power in his direction（Such as moment of flexure and shearing）Influence, only by the pulling force or pressure in a direction, improve the essence of weighing of weighing sensor Degree.
What the purpose of patent of the present invention was realized in：Gravity direction analyzer, it is characterized in that：Analyzer includes garlic mortar Post, garlic mortar post hemisphere epicranial plate, garlic mortar hemispherical head base, six orientation pressure-strain piece 1-6, pressure-strain piece pressure data are shown Instrument, garlic mortar post are put on garlic mortar hemispherical head base and are pressed on six orientation pressure-strain piece 1-6, garlic mortar post hemisphere epicranial plate and garlic Mortar hemispherical head base is connected, and six orientation pressure-strain piece 1-6 are connected by input interface and pressure-strain piece pressure data display instrument Connect.
Described garlic mortar column bottom is half sphere shape, and top is cylinder.
Described garlic mortar hemispherical head base is the interior cup dolly for having matrix sphere.
Feature：Garlic mortar post is finely adjusted according to the data of pressure-strain piece pressure data display instrument, until pressure-strain piece Untill the data of pressure data display instrument are equal, it is determined that the weight beam is in upright position.
Brief description of the drawings
