AI Technical Summary

Technical Problem

In existing drilling equipment, the cylinder extension rod can only be fully extended or fully retracted, making it impossible to flexibly adjust the drilling depth. This results in the need to readjust the cylinder position when drilling holes of different depths.

Method used

The system employs a combination of a first limiting nut and a first lead screw. When the first moving seat is driven downward by the first cylinder, the limiting nut blocks the moving seat, thus adjusting the drilling depth. Simultaneously, the second cylinder and the second lead screw are used to adjust the front and rear positions of the drilling assembly, and the movement range is limited by the slide groove and guide rod.

Benefits of technology

It enables flexible adjustment of drilling depth without adjusting the cylinder position, improving drilling accuracy and efficiency, and simplifying the operation process.

Abstract

The utility model discloses a gang drill moving and positioning structure which comprises an installation seat and a drilling mechanism, a first air cylinder and a first lead screw are installed on the installation seat, an extension rod of the first air cylinder and the first lead screw are vertically arranged, and the first lead screw is in threaded connection with a first limiting nut. The drilling mechanism comprises a first moving seat and a gang drill assembly, the first moving seat is mounted on the mounting seat in a manner of moving up and down, the first moving seat is fixedly connected with the extension rod, and a part of the first moving seat is located right above the first limiting nut; the first limiting nut is arranged under one part of the first moving seat, when the first air cylinder drives the first moving seat to move downwards, the first limiting nut can stop the first moving seat from moving downwards, then the lowest position of the gang drill assembly is limited, the drilling depth is controlled, and the position of the first air cylinder does not need to be adjusted.
