Abstract

This thesis gives a brief introduction of the conception of automatic locking screw machine, The components and classification of automatic locking screw machine, the characteristics of air pressure drive, and the domestic and foreign status of the development.
This thesis designs the overall scheme of lead-screw driving system, decides the technique parameter of lead-screw driving system. Meanwhile, it designs the technique parameter of lift hydraulic cylinder and the structure of lift hydraulic cylinder.
This thesis focus on the analyzing of the transmission system of automatic locking screw machine, analyses the working principle of air pressure clamping system, draws a schematic and studies it, which helps a lot to make a improvement in charting, greatly improves the depth of understanding of the machinery.
Key Words: lead-screw, cylinder, air pressure drive, screw transmission
