Embodiment Construction

[0013] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] like figure 1 As shown, a five-dimensional force sensor of the present invention includes two two-dimensional force sensors and a beam 6 . Each two-dimensional force sensor includes a rectangular section beam 1 . The rectangular section beam 1 comprises opposite top and bottom faces, opposite first and third sides 11 , and opposite second and fourth sides 12 . A first through hole 1101 and a second through hole 1102 arranged up and down are opened on the first side 11 and the third side. The axes of the first through hole 1101 and the second through hole 1102 are parallel to each other and located in the same vertical plane. A first through groove 1103 is formed between the first through hole 1101 and the second through hole 1102 . The first through groove 1103 communicates with the first through hole 1101 and the second through h...

Abstract

The invention discloses a five-dimensional force sensor which comprises two two-dimensional force sensors and a cross beam, wherein each two-dimensional force sensor comprises a rectangular section beam; a first through hole, a second through hole and a first through groove are arranged on the first side surface and the third side surface of the rectangular section beam; a third through hole, a fourth through hole and a second through groove are arranged on the second side surface and the fourth side surface; strain gauges are arranged on the two sides of the first through hole, the second through hole, the third through hole and the fourth through hole respectively; a fifth through hole, a sixth through hole, a seventh through hole and an eighth through hole are arranged on the cross beam; a third through groove is arranged between the fifth through hole and the sixth through hole; a fourth through groove is arranged between the seventh through hole and the eighth through hole; strain gauges are arranged on the two sides of the fifth through hole, the sixth through hole, the seventh through hole and the eighth through hole respectively; and the cross beam is fixedly connected between the top ends of the two two-dimensional force sensors. The five-dimensional force sensor has a simple structure, and is convenient to manufacture and suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to a multi-dimensional force sensor, in particular to a five-dimensional force sensor. Background technique [0002] Multi-dimensional force sensors can measure multiple force components in three-dimensional space, and are widely used in many fields such as robotics, automatic control, and virtual reality technology. At present, a lot of research has been done on the multi-dimensional force sensor, and a variety of patented technologies have been formed. However, as a mechanical quantity-electricity conversion device, the sensor is mainly realized by a certain force-sensitive elastic structure. The action of the force is converted into the deformation of the structure, and the strain gauge is pasted at the deformed place, and the strain gauge and the sensitive element undergo elastic deformation together, and the deformation of the strain gauge corresponds to its resistance, which realizes the conversion of mechanical quantity to ...
