Abstract

A positioning drilling system for an I-beam and a box beam, comprising a pad beam, wherein the upper end of the pad beam is provided with a height adjustment pad, the upper end of the height adjustment pad is provided with a workpiece, tooling bed-jigs are arranged at two sides of the height adjustment pad on the upper end of the pad beam and are provided with a plurality of lateral adjustment screw rods, the upper end of the workpiece is provided with a drilling mold plate, and both ends of the drilling mold plate are respectively fixed to the tooling bed-jigs at two sides of the height adjustment pad by positioning pins. The system can accurately locate and drill the I-beam and the box beam, ensure the accuracy of the workpiece hole group and greatly improve the efficiency, and is suitable for the factory manufacturing of batch I-beams or box beams.

Description

technical field [0001] The invention relates to a positioning drilling system for I-shaped beams and box-shaped beams. Background technique [0002] I-beams and box girders are often used in the field of building construction, but in the past, a single bar was used to drill holes with a small formwork, which was not accurate enough and could not meet the needs of batch and high-efficiency production. Contents of the invention [0003] The purpose of the present invention is to provide a positioning drilling system for I-beams and box girders, which solves the problems of low drilling precision and low drilling accuracy caused by the use of single rods in the existing building construction. Can not meet the problem of mass production and high-efficiency production. [0004] The technical solution adopted to achieve the above purpose is a positioning drilling system for I-beams and box beams, including a pad beam, the upper end of the pad beam is provided with a height-adju...
