The invention discloses a pulling and pressing both-way decoupling and parallel connecting three-dimensional
force sensor. A loading plate is arranged on an outer frame and provided with three nuts with the center connecting lines forming a regular triangle. The lower ends of supporting studs meshed with the nuts are connected with a force measuring plate. Three horizontal adjusting bolts are arranged on the side face of the force measuring plate, wherein the included angle formed by the corresponding center lines of the horizontal adjusting bolts is 120 degrees. The bolt heads of the bolts are located outside the outer frame. The force measuring plate is further provided with three vertical adjusting bolts with the center connecting lines forming a regular triangle, and the lower ends of the vertical adjusting bolts are located on a bottom plate of the outer frame.
Four force measuring
branch chains are arranged between the force measuring plate and the outer frame, the structures of the three
horizontal force measuring
branch chains on the side face of the force measuring plate are the same, the center lines of the three
horizontal force measuring
branch chains on the side face of the force measuring plate are located on the same horizontal plane and intersect with one another at one point of the force measuring plate, the 120-degree included angle is formed by the corresponding center lines of the three
horizontal force measuring branch chains and
vertical force measuring branch chains are arranged below the force measuring plate, wherein the center lines of the
vertical force measuring branch chains are perpendicular to the center lines of the three horizontal force measuring branch chains and pass through the intersections of the center lines of the three horizontal force measuring branch chains. The pulling and pressing both-way decoupling and parallel connecting three-dimensional
force sensor is small in inter-dimensionality
coupling, high in measuring precision, simple and compact in structure and convenient to assemble and adjust, and the both-way decoupling measurement on the three-dimensional pulling and pressing force can be achieved easily.
