AI Technical Summary

Technical Problem

The existing workpiece drilling positioning cannot effectively suppress drilling offset, mainly due to positioning datum error, insufficient clamping stability and cutting force changes caused by tool wear. Conventional methods cannot compensate for these issues in real time, making it difficult to completely eliminate the offset problem.

Method used

A drilling device and anti-offset positioning structure are adopted, including a transmission roller group, an offset positioning component and a multi-stage positioning seat. By using the combination of adjusting screw, clamping block and positioning top seat, the workpiece is stably clamped and the power transmission of the drill bit is achieved. The lead screw structure is used to compensate for the thickness difference of the workpiece, control the rotation speed and depth of the drill bit, and suppress the radial offset of the drill bit.

Benefits of technology

During the drilling process, the vertical stability of the workpiece and the precise control of the drill bit were achieved, effectively suppressing drilling offset, adapting to the fluctuation of the reference surface in mass production, and improving drilling accuracy and efficiency.
