Abstract

The invention provides a screw rod. The screw rod comprises a cylindrical body, wherein a connecting part is convexly arranged at one end of the body of the screw rod, a through groove is formed on the connecting part, and an annular positioning piece is also arranged on the body. The positioning piece is arranged on the screw rod provided by the invention, the screw rod arranged in such a way can be positioned exactly during a drive process, and the requirements of production and processing are met.

Description

technical field [0001] The invention relates to a mechanical part, in particular to a screw rod. Background technique [0002] Screws are ideal products for converting rotary motion into linear motion, or converting linear motion into rotary motion. The screw rod consists of a screw, a nut and a ball. Its function is to convert rotary motion into linear motion, which is a further extension and development of the ball screw. The significance of this development is to change the bearing from rolling motion to sliding motion. Due to its small frictional resistance, lead screws are widely used in various industrial equipment and precision instruments. [0003] During the transmission process of the screw rod, it is sometimes necessary to limit its transmission position, but the existing screw rods often cannot meet this requirement. [0004] Therefore, it is necessary to improve the existing screw mandrel to solve the above problems. Contents of the invention [0005] Th...
