Problems solved by technology

Among them, the symmetry of the cross beam structure is good, the design is convenient, the theoretical relationship is simple and easy to analyze, but it has the disadvantages of radial effect, the calibration matrix is ​​an approximate solution, and the number of strain gauges is large; Lateral effects of the beam structure, but with increased cross-coupling
The existing technology also includes a six-dimensional force sensor with a double cross beam structure, which reduces the cross-coupling between dimensions while increasing the number of strain gauges to 32 pieces, which increases the complexity of the elastic body structure and the difficulty of manufacturing.

Abstract

The invention discloses a six-dimensional force sensor of an eight-beam structure. The six-dimensional force sensor is characterized by comprising a stress disc, a shell, a base, an elastic beam, a plug connecting piece and a plug. The stressed disc is connected with a force application device through a screw hole; the plug connecting piece is installed on the outer side face of the shell; the plug is fixed on the plug connecting piece; a base boss of the base is mounted in the shell; the elastic beam comprises a disc beam body and eight supporting beams; the disc beam body is connected with the stressed disc; stress concentration holes are formed in the eight supporting beams; the two sides of the center of the stress concentration hole in each supporting beam are each provided with two strain gages; the elastic beam is mounted on the base. The sensor has the advantages of being high in output precision, simple and compact in structure, simple in process, few in strain gauge, high insensitivity and decoupling precision, convenient to install and use and the like.

Description

technical field [0001] The invention relates to the technical field of strain sensors, in particular to a six-dimensional force sensor with an eight-beam structure. Background technique [0002] The six-dimensional force sensor is rich in force measurement information, and it is a sensor that can detect three components of space and three components of torque.
