AI Technical Summary

Technical Problem

The current production process of automotive front door guide rails requires the use of two different sets of clamps to fix its ends and side walls respectively, resulting in low production efficiency.

Method used

A clamping fixture was designed, including a loading base and multiple sets of cylinder-driven limiting components, which can simultaneously and stably position and clamp the end and side of the front door guide rail of an automobile. Through the cooperation of the side limiting components and the end limiting components, the full or half coverage positioning and clamping of the front door guide rail can be achieved, simplifying the processing flow.

Benefits of technology

This technology enables efficient clamping and machining of automotive front door guide rails, improving production efficiency. Furthermore, the avoidance groove prevents interference between the base and the cutting tool, ensuring smooth machining.
