Abstract

The application provides a six-dimensional force sensor, including: a housing, a base, and a sensor body, the sensor body includes a moving platform, a support body, and multiple sets of stress rods; the multiple sets of stress rods are in pairs, each The group of stress rods includes a first stress rod and a second stress rod, and the plane where the first stress rod and the second stress rod are located can be enclosed to form a regular polyhedron structure; the first stress rod and the second stress rod The second stress rods are arranged on the outer side of the support body in a circular array; the first stress rods and the second stress rods are arranged between the support body and the moving platform, and the The first stress rod and the second stress rod are arranged at a certain angle with each other. The new layout method of circumferential rotational symmetry of multiple sets of stress rod groups proposed by this application reduces the coupling error caused by the structure of the sensor in the process of force / torque measurement and perception, thereby improving the stability and accuracy of measurement.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a six-dimensional force sensor. Background technique [0002] A multidimensional force sensor refers to a force sensor that can measure force and moment components in more than two directions at the same time. In the Cartesian coordinate system, force and moment can be decomposed into three components respectively. Therefore, the most complete form of multidimensional force is A six-dimensional force / torque sensor, that is, a sensor capable of simultaneously measuring three force components and three torque components. [0003] In the prior art, the most common six-dimensional force / moment sensor mainly adopts a beam structure, and the beam structure can be divided into a vertical beam structure and a beam structure. The main problem that causes high coupling is usually to apply force in one direction, and force signals will also be generated in other directions where no force i...
