Embodiment 1
[0044] Such as Figure 1-2 As shown, a kind of micro-thrust measuring device comprises support 1, and the upper side of described support 1 is provided with fixed frame 3, and described fixed frame 3 is equipped with two left and right symmetrical XY displacement platforms 2, and described fixed frame 3 is provided with a force arm 9, and one end of the force arm 9 is movably connected with the support 1 through a thimble 8, and the force arm 9 is provided with a movable thruster fixing seat 10, and each of the XY displacement platforms 2 is connected to the force arm 9 through a twisted wire 7, and the connection line between the twisted wire 7, the force arm 9 and the twisted wire 7 on the XY displacement platform 2 forms a right-angled trapezoid.
[0045] In this application: when the thruster starts to work, the force arm 9 is rotated by a certain angle θ around the thimble 8 to provide measurable angular displacement for subsequent measurement. The theoretical derivation...
Embodiment 2
[0064] Such as figure 2 As shown, on the basis of Embodiment 1, each of the XY displacement platforms 2 is provided with a plurality of fixing holes 6 . The fixing holes 6 are used to fix the upper ends of the twisted wires 7 , and multiple fixing holes 6 are provided for installing twisted wires 7 of different lengths.
Embodiment 3
[0066] Such as figure 2 As shown, on the basis of Embodiment 1, each of the XY displacement platforms 2 is provided with a mounting hole 5 . The setting of the mounting hole 5 is used to fix the XY displacement platform 2, and the XY displacement platform 2 can move up and down left and right, so that the position of the fixing hole 6 can move up and down or move left and right, thereby facilitating adjustment of the length of the twisted wire 7.
