Problems solved by technology

When the workpieces are produced in batches, this process is not advisable. It is not advisable to use skilled fitters to draw lines manually on batches of workpieces.
Manual scribing by fitters requires a high level of professional skills, and the production efficiency of manual scribing is also very low, and it is not the final process to ensure the position tolerance of the workpiece
The operator of the drilling machine is the controller of the tolerance of the porous position on the plane of the workpiece. When he finishes drilling the holes, the position between the holes may cause errors due to the operation, which does not meet the design requirements.

Embodiment Construction

[0019] like figure 1 Among them, a mold drilling device, the template 3 is provided with at least one positioning hole 6, and the positioning hole 6 is coaxially provided with a positioning sleeve 2;

[0020] The positioning hole 6 is larger than the aperture of the processing hole, and the aperture of the positioning sleeve 2 is equal to the aperture of the processing hole.

[0021] The positioning sleeve 2 is provided with a step, and the step extends into the positioning hole 6 . The outer edge of the step is used as the positioning datum of the positioning sleeve 2 . to ensure positioning accuracy.

[0022] The positioning sleeve 2 and the template 3 are connected by welding.

[0023] The bottom surface of the template 3 is a reference plane. To ensure machining accuracy, one of the datum surfaces must be the bottom surface of the template 3 .

[0024] like figure 1 , figure 2 During production, first use precision machining, such as: boring and milling methods to ...

Abstract

The invention relates to a cover-die hole-drilling device, which relates to an auxiliary device for hole-drilling machining, wherein at least one positioning hole is arranged on a template, and a positioning sleeve is coaxially arranged on the positioning hole; and the hole diameter of the positioning hole is larger than that of a machined hole, and the hole diameter of the positioning sleeve is equal to that of the machined hole. The problem of workpiece-position tolerance control is solved through the positioning sleeve and the template arranged on the cover-die hole-drilling device provided by the invention. Requirements on the technical grade of an operator are reduced, production links are decreased, the quality of products is ensured, the production benefit is improved, and the cover-die hole-drilling device is worthy of being widely popularized.

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...
