AI Technical Summary

Technical Problem

The transmission mechanism of the existing automatic traction device when the casing is expanded is difficult to disassemble and maintain, and it is prone to locking or slipping wire problems, resulting in more troublesome maintenance.

Method used

An automatic traction device is designed. By setting a rotary plate on the outer wall of the rotary rod, a movable block is set at one end of the rotary plate, a limit groove is set inside the groove body, a limit plate is set inside the limit groove, a movable groove and a fixed rod are set on the outer wall of the limit plate, and a spring is set between the limit plate and the groove body, so that the limit plate can return to its initial position, thereby achieving convenient disassembly and adjustment of the transmission mechanism.

Benefits of technology

This device makes the transmission mechanism easy to disassemble and maintain, avoids maintenance difficulties caused by fixed connections in traditional devices, and improves the convenience of subsequent maintenance.

Abstract

The utility model discloses an automatic traction device for sleeve expansion, and particularly relates to the technical field of sleeve processing, the automatic traction device comprises a workbench and a plurality of supporting legs fixedly connected with the bottom end of the workbench, and the top of the workbench is fixedly connected with a sliding rod. A rotating plate is arranged on the outer wall of a rotating rod, a movable block is arranged at one end of the rotating plate, a limiting groove is formed in a groove body, a limiting plate is arranged in the limiting groove, a movable groove is formed in the outer wall of the limiting plate, a fixed rod is arranged on the outer wall of the limiting plate, and a spring is arranged between the limiting plate and the groove body, so that the limiting plate can return to the initial position; in the utility model, most traction devices adopt transmission mechanisms which move oppositely in two directions to carry out traction treatment on the sleeve, the transmission mechanisms need to be frequently used, so that parts such as internal gears of the transmission mechanisms need to be overhauled and maintained regularly, and the transmission mechanisms are convenient to disassemble and maintain, so that the subsequent overhaul and maintenance of the transmission mechanisms are relatively convenient.
