The invention discloses a multi-axis force sensor. The multi-axis force sensor comprises an elastic body and strain components, wherein the elastic body comprises an upper platform, a lower platform and at least three force measuring columns arranged between the upper platform and the lower platform; each force measuring column comprises a first force measuring arm, a second force measuring arm and a connecting arm; the first force measuring arms are fixed on the peripheral wall of the upper platform, the second force measuring arms are fixed on the peripheral wall of the lower platform, one ends of the connecting arms are connected with the first force measuring arms, and the other ends of the connecting arms are connected with the second force measuring arms; the strain components are placed at two ends of the first force measuring arms, two ends of the second force measuring arms and the middles of the connecting arms. The multi-axis force sensor disclosed by the invention has the advantage of simple and compact structure, accurate measurement, high sensitivity and the like.
Description
technical field [0001] The invention relates to the technical field of sensors, in particular to a multi-axis force sensor. Background technique [0002] Multi-axis force sensors are widely used in aerospace, automobiles, robots, automation equipment, medical equipment, sports equipment and other fields, such as six-component force balances in wind tunnel tests, six-dimensional wheel force sensors in automotive road tests, and car collision The simulated human multi-axis force sensor in the test, etc. [0003] The key to the design of the multi-axis force sensor lies in the design of the elastic body, the patching of the strain gauge and the bridge assembly method. In order to obtain high measurement accuracy, the existing multi-axis force sensor often needs to design a relatively complex elastic body structure, which is not easy to assemble, and requires high precision for the position of the strain gauge, which is inconvenient to operate and cannot meet the use requiremen...
