Description
Technical field
The present invention relates to the method for a kind of Multi-angle drilling jig processing, there is for processing and manufacturing the drill jig of the large complicated part of Multi-angle hole.
Background technology
Along with aviation part functionalization and integrated requirement, Multi-angle hole class aviation part difficulty of processing and precision more and more higher, existing lathe is difficult to disposable machining when processing this type of part drill jig, there is processing accumulated error, often cause the machining accuracy of drill jig to meet design requirement.This type of drill jig needs frequent inverting reference in the fabrication process and repeatedly processes, and not only adds manufacturing cost and difficulty, also often delays manufacturing schedule, has a strong impact on the manufacturing schedule of aviation part, and reduce part by stability and assembly quality.
Summary of the invention
The technical problem to be solved in the present invention is to provide the method for a kind of Multi-angle drilling jig processing, the method not only reduces the difficulty of processing of multi-angle drill jig, and improve machining accuracy, meet design tolerance requirement, ensure the manufacturing schedule of frock, and then improve the precision and stability of aviation part, ensure Assembly of the parts quality.
For overcoming the above problems, the concrete technical scheme of this method is as follows: a kind of method of Multi-angle drilling jig processing, comprises the following steps:
1) fine finishining drill jig baseplane, reaches jig design required precision;
2) on drill jig, process waist type drill bushing bottom outlet: the center determining drill bushing bottom outlet on Digit Control Machine Tool, adopt with φ be nominal diameter drill bushing and centrally biased φ/2+0.5mm symmetry drill the circular hole that two diameters are φ, and ensure that the tolerance of circular hole is H7; The unnecessary amount removing two circular holes is waist type drill bushing bottom outlet, and the width of this waist type drill bushing bottom outlet is
3) offset distance and bias direction is looked for: after waist type drill bushing bottom outlet machines, by the feature of numerical control three coordinate measuring engine measurement drill bushing bottom outlet, simulate the center of waist type drill bushing bottom outlet, and contrast with theoretical center point coordinates, draw the Distance geometry bias direction of actual waist type drill bushing bottom outlet centre coordinate and theoretical waist type drill bushing bottom outlet centre coordinate;
4) determine the X-Y scheme of drill bushing: the X-Y scheme drawing waist type drill bushing according to the measured data of numerical control three coordinate measuring engine measurement, and increase the magnitude of interference and Linear cut polishing amount according to waist molded breadth degree, drill bushing increases machining benchmark and installation direction mark simultaneously; Draw the actual bore position of offset distance and bias direction determination drill bushing Multi-angle hole according to the 3rd step, make up the mismachining tolerance of drill bushing bottom outlet;
5) 2-D data of drill bushing is input in Linear cut, processes satisfactory waist type drill bushing, and carry out polishing process, ensure drawing tolerance;
6) according to liquid nitrogen Method for Installation, drill bushing is installed in drill bushing bottom outlet, and ensures drill bushing direction.
The method of this Multi-angle drilling jig processing has the large complicated aviation part drill jig of Multi-angle hole especially for processing and manufacturing, this method reduce secondary or repeatedly process, the operation such as Reference Transforming and measurement adjustment, simplify processing method, ensure that the disposable precision machined of multi-angle drilling mould, substantially increase production efficiency, and significantly improving stability and the assembly quality of part processing, the factors such as machine tool accuracy, stroke and cumulative errors that namely avoid are on the impact of Multi-angle drilling jig.
