Abstract
Description
technical field
[0001] The invention relates to an auxiliary device for drilling, in particular to a mold drilling device. Background technique
[0002] In ordinary mechanical processing, it is often necessary to process multiple holes with high position tolerances on a plane, such as flange covers, and internal threads need to be drilled with a twist drill on a drilling machine.
[0003] The existing processing procedure is that the fitter draws a line on a workpiece plane that needs to process multiple holes with relevant position tolerances according to the drawing requirements, punches and marks the holes, the driller fixes it on the drilling machine, and then inserts the standard drill Put it into the spindle of the drilling machine, and find the punching position manually to prevent the position error caused by the drilling from exceeding the position tolerance zone required by the drawing, which will affect the product quality.
[0004] For a single workpiece or a sm...
