Technical Field

[0001] The utility model relates to the technical field of ball screw detection, in particular to a ball screw accuracy detection device. Background Art

[0002] Ball screws are the most commonly used transmission elements in tool machinery and precision machinery. Their main function is to convert rotational motion into linear motion, or to convert torque into axial repetitive force. They also have the characteristics of high precision, reversibility and high efficiency. Due to their very small friction resistance, ball screws are widely used in various industrial equipment and precision instruments, including ball screws and screw sleeves.

[0003] Before a ball screw is put into use, it is usually necessary to test the ball screw. Currently, the bending of the rod is usually tested. There is a lack of equipment for precision testing of ball screws. The precision test is to detect the accuracy of the match between the number of turns of the ball screw and the distance the screw sleeve moves. Utility Model Content
