Description

A small double-flange three-force measurement structure

Technical Field

The utility model relates to the technical field of three-dimensional force sensors, in particular to a small double-flange three-dimensional force measurement structure, which has the advantages of simple structure, low cost, small size and large installation surface.

Background Art

The three-dimensional force sensor is based on a strain-type weighing sensor and adopts the resistance strain principle. It is also called a strain-type three-dimensional force sensor. It consists of an elastic element, a resistance strain gauge and a Wheatstone bridge circuit. The weight of the object being weighed acts on the elastic element, causing it to deform and generate strain. The resistance strain gauge attached to the elastic element converts the strain proportional to the weight of the object into a resistance change, and then converts the resistance change into a voltage output through a Wheatstone bridge circuit. The measurement and measurement tasks can be completed by measuring the voltage output value through a display instrument. Existing three-dimensional force sensors mostly use cubic strain beams, and their mounting surface is smaller than the overall specifications. If the requirements of a larger mounting surface are to be met, it is often necessary to select a larger sensor, and its structure is more complex and relatively expensive.

Therefore, it is of great practical significance to develop a three-force measurement structure with simple structure, low cost, small size and large installation surface.

Utility Model Content

The upper transfer prism and the lower transfer prism are symmetrically arranged relative to the patch square column. The cross-section of the patch square column is a square, and patches are pasted on the four peripheral surfaces of the patch square column.

The small double-flange three-force measurement structure of the utility model has a reasonable structural design. The patches are arranged on the patch square column. The patch square column is fixedly connected to the upper flange and the lower flange respectively through the upper transfer prism and the lower transfer prism. The transfer part adopts a prism structure, which can ensure the reliability of the overall structure. At the same time, the larger upper and lower flanges give it a larger installation surface under small specifications.
