Description
Technical Field
The utility model relates to a measure examining utensil of ball screw helical pitch error.
Background
The ball screw is an ideal product for converting rotary motion into linear motion or converting linear motion into rotary motion. The ball screw is the most commonly used transmission element on tool machinery and precision machinery, and has the main function of converting rotary motion into linear motion or converting torque into axial repeated acting force, and has the characteristics of high precision, reversibility and high efficiency. Ball screws are widely used in various industrial equipments and precision instruments due to their small frictional resistance. The ball screw consists of a screw rod, a nut, a steel ball, a preforming piece, a reverser and a dust remover. Its function is to convert the rotary motion into a linear motion, which is a further extension and development of the acme screw, the important meaning of this development is to change the bearing from sliding motion to rolling motion.
In various operation processes, the positioning of the screw rod is very important, and the highest precision needs to reach 0.02 mm. In order to ensure the positioning accuracy, the lead difference of the screw rod should be checked and confirmed during the maintenance process. The transmission pair of the screw rod consists of a ball nut, a ball and a ball screw, and the measurement of the lead difference can not be completed by a conventional measuring tool. In the original maintenance process, no measuring tool is provided, and personnel can only judge the states of the screw rod and the ball nut according to self maintenance experience.
