Embodiment Construction
[0013] The present invention adopts the loading mode of fixing the screw to be tested and exerting force on the nut to be tested, and uses a pressure sensor and a displacement sensor to sample the axial load and micro-displacement of the nut to be tested respectively, wherein the pressure sensor and the nut to be tested are fixed Even, the displacement sensor is installed on the bed through the displacement sensor fixture to measure the vertical displacement of the right end face of the nut under test. By processing the sampled data, the axial static stiffness curve of the ball screw under the tension and compression state can be drawn respectively, and the value can be finally calculated, so as to realize the measurement of the axial static stiffness of the ball screw. The specific content is as follows.
[0014] to combine figure 1 , the horizontal static stiffness measuring device of the ball screw pair of the present invention includes a loading assembly, an anti-rotation ...
