Abstract

The invention discloses a high-speed screw and screw pair comprehensive examination test bed comprising a granite base, a floating guide rail and linear guide rails. The floating guide rail and the linear guide rails are arranged on the granite base parallelly. A linear guide rail holding plate is arranged on the linear guide rails, and the lower side of the linear guide rails is connected with a linear motor arranged on the granite base. A floating guide rail holding plate used for mounting a probe system is arranged on the floating guide rail and is connected with the linear guide rail holding plate through a connecting mechanism. By the aid of the test bed, a function of testing the features such as geometric accuracy, positioning accuracy, backlash, driving speed and acceleration, natural frequency, vibration mode, damping, and static and dynamic stiffness, friction torque and fatigue in the high-speed screw and screw pair and a function of testing stability in the high-speed screw and screw pair can be realized, and the rapid and accurate evaluation on most performance parameters of a precision ball screw can be given.
