Embodiment Construction

[0015] exist figure 1 In the three-dimensional schematic diagram of the deformable parallel three-dimensional dynamic force sensor shown, there are four support columns on the fixed base 1, among which three side support columns 15 of equal height are arranged in an equilateral triangle, and the other support column is arranged at the center of the equilateral triangle It is a central support column 14, and the height of the central support column is greater than the height of the other three side support columns. A guide rail 13 is respectively arranged between each side support column and the center support column, and the three guide rails have the same angle with the fixed base. A force-measuring branch is set up on each guide rail, such as figure 2 As shown, each force-measuring branch includes a cylindrical pair 5, a first rotating pair 8, a connecting rod 9, a second rotating pair 10, tension-compression single-dimensional force sensors 4, 6 and springs 3, 7. Among th...

Abstract

The invention provides a deformable parallel three-dimensional dynamic force sensor which mainly comprises a fixed base, a force measuring plate and three force measuring branches with the same structure. On the fixed base, three equal-altituded side support columns are distributed in a normal triangle, and the other center support column is located at the center of the normal triangle. A guide rail of the same angle with the fixed base is arranged between each side support column and the center support column. Each force measuring branch comprises a cylindrical pair, a first rotation pair, a connection rod, a second rotation pair, a tension and compression type single-dimensional force sensor and a spring. The lower end of each force measuring branch is in sleeve joint with a guide rail, and the upper end is connected with the force measuring plate. According to the invention, force measuring requirements of a space three-dimensional dynamic force can be met; when measurement is carried out, the sensor can produce large deformation, and the mapping relationship between input and output is always constant during the deformation; and the sensor is assembled by separate components, has the advantages of symmetrical structure, simple manufacture and easy serialization, and can be applied to a variety of occasions needing space three-dimensional dynamic force measuring.
