A hydraulic control system for an automobile production workshop

Abstract

This invention relates to the field of hydraulic system technology, specifically to a hydraulic control system for an automobile production workshop. The system includes a support frame, with a drive motor embedded inside. The outer wall of the support frame has a groove. The power output end of the drive motor is connected to a threaded rod, and a slider is fitted around the threaded rod. The invention utilizes the drive motor to rotate the threaded rod, which passes through a through hole into the slider, facilitating the slider's sliding along the support frame. This, in turn, causes the slider to move a movable arm along the groove. The movable arm moves the support mechanism to different positions, adapting to automobiles of different sizes and lengths while maintaining stability. A limiting plate is welded to the top of the slider through the support frame, enhancing the load-bearing capacity of the movable arm. A fitting plate is located at the bottom of the movable arm, fitted axially outside the support frame, facilitating stable sliding of the movable arm.
