Abstract

The invention relates to a method for part curve surface hole site drilling line drawing with a three-dimensional model. The method for the part curve surface hole site drilling line drawing with the three-dimensional model includes the following steps: (1) unfolding a curve surface of a part and correspondingly unfolding a hole site on the curve surface under the condition of a three-dimensional mathematical model, (2) conducting projection on two-dimensional model lines of the unfolded part and the unfolded hole site, and using a numerical controlled plotter to draw the two-dimensional model lines on a polyester film, (3) attaching the polyester film to the curve surface of the part, aligning the model lines with the edge of the part, and using a punch to make a round hole central point on the surface of the part, and (4) taking down the polyester film, and using a drilling tool to drill in the dotting position. The method for the part curve surface hole site drilling line drawing with the three-dimensional model can not only improve machining accuracy and machining efficiency of the hole site on the curve surface, but also reduce machining cost.

Description

The part Position of Hole Series on Curved Surface layout for drilling method that threedimensional model is arranged

Technical field

The present invention relates to a kind of part Position of Hole Series on Curved Surface layout for drilling method that threedimensional model is arranged, mainly be applicable to the curved surface part of threedimensional model.

Background technology

During existing Position of Hole Series on Curved Surface layout for drilling, normally press the size line processing of threedimensional model, during line, dimensional measurement is carried out in the ruler bending, because the hole is positioned on curved surface, dimensional measurement is very inconvenient, if hole number is more, just causes the line difficulty large, the line precision is low, line efficient is low, and then affects hole crudy and efficient.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of part Position of Hole Series on Curved Surface layout for drilling method that threedimensional model is arranged, and the method not only improves machining accuracy and the working (machining) efficiency of Position of Hole Series on Curved Surface, and has reduced processing cost.

For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of part Position of Hole Series on Curved Surface layout for drilling method that threedimensional model is arranged comprises the following steps:

1) under the three-dimensional mathematical model condition, the curved surface of part is launched, also launch accordingly the position, hole on it simultaneously;

The two-dimentional loft that 2) will launch rear part and position, hole carries out projection, and with calcomp, two-dimentional loft is plotted on polyester film;

3) polyester film is fitted in the part curved surface, loft is alignd with part edge, with punching pin, center of circular hole point is beaten on piece surface;

4) take off polyester film, hole by getting the position ready with boring bar tool.

Characteristics of the present invention are as follows: 1, curved surface boring need not to have saved the line time by the size line, shortens the part process-cycle; 2, utilize the data of the direct Developing Surface of three-dimensional mathematical model accurate, borehole accuracy is high, and the borehole accuracy machining accuracy of ruling is high; 3, when hole number is more, can once complete expansion, get ready, improve drilling efficiency 30%; 4, polyester film can repeatedly be got ready, is fit to produce in enormous quantities, can cut down finished cost simultaneously.

The specific embodiment

A kind of part Position of Hole Series on Curved Surface layout for drilling method that threedimensional model is arranged comprises the following steps:

1) under the three-dimensional mathematical model condition, the curved surface of part is launched, also launch accordingly the position, hole on it simultaneously;

The two-dimentional loft that 2) will launch rear part and position, hole carries out projection, and with calcomp, two-dimentional loft is plotted on polyester film;

3) polyester film is fitted in the part curved surface, loft is alignd with part edge, with punching pin, center of circular hole point is beaten on piece surface;

4) take off polyester film, hole by getting the position ready with boring bar tool.
