Finish machining method for blank part with basic hole

Abstract

The invention discloses a finish machining method for a blank part with a basic hole. The method comprises the steps that 1, a vacuum sucker positioning tool is prepared; 2, the part is corrected, anda straightening tool is fixed through the vacuum sucker positioning tool; 3, a coordinate system is built, and the part is installed in a corresponding positioning groove I; 4, a circular slitting knife is installed, the upper surface of the part is machined, and the basic hole is set to ensure that the distance between the basic hole and the upper surface is within a set range; 5, the part is rotated by 180 degrees around the X axis, and the part is installed on a corresponding positioning groove II on the surface; 6, a circular slitting knife is installed, the surface is calibrated by usingthe same basic hole, and machining is carried out; 7, the part is rotated by 180 degrees around the X axis and is installed on a positioning groove III, and a complete shape is machined; and 8, a chamfering knife is installed, a chamfer is machined, then the part is detached, burrs are removed, and machining is completed. According to the finish machining method for the blank part with the basichole, the machining precision is high, and the working efficiency is high.

Description

technical field [0001] The technology belongs to the field of numerical control machining, and in particular relates to a finishing method for rough parts with reference holes. Background technique [0002] Stretched wool with reference holes is often encountered in actual production. For the bending and deformation of the stretched aluminum profile wool with reference holes, the processing is stressful, and the size is not easy to control. It needs to be processed once and corrected once. The correction takes a long time. The processed holes are not in a straight line, and the contour size of the holes is not easy to control. It needs to be turned over and processed, and the reference hole will cause inaccurate reference positioning deviation due to deformation or positioning deviation of stretched wool parts, which brings great difficulty to the processing process and often leads to processing completion caused by inaccurate reference positioning of parts. parts do not me...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a method for finishing wool parts with reference holes. The positioning of the parts is carried out by a vacuum suction cup positioning tool, and a plurality of positioning grooves are provided on a vacuum suction cup positioning tool, which can adjust the different parts. The surface is positioned and processed, and the calibration is performed through the same reference hole at the same time, which solves the technical problems of difficult control of the processing size, long calibration time, and poor cost and quality in the prior art.
