AI Technical Summary

Technical Problem

The existing measurement and marking process in the positioning drilling process of the jack push cylinder bottom is time-consuming and has low accuracy, which affects the dimensional accuracy of subsequent drilling. Only one push cylinder bottom can be processed at a time, and the disassembly and assembly of the tooling back and forth is time-consuming and labor-intensive, seriously affecting production efficiency.

Method used

The design is suitable for the mechanism of pushing the cylinder bottom for positioning drilling with different cylinder diameters, including adjustable positioning hoop, positioning hole, positioning hoop locking hole, partition plate, adjustable gasket and other components. It is connected by locking bolts and nuts to achieve precise positioning of the drilling machine drill bit, simplify the processing process, and improve drilling accuracy and efficiency.

Benefits of technology

Precisely locate drilling holes, improve product matching accuracy, reduce rework rate, reduce lifting auxiliary time, shorten processing cycle, and improve production efficiency.
