[0021] The utility model will be further described below in conjunction with the accompanying drawings.

[0022] The orientations mentioned in this specification are based on the orientations of the mechanical parts marking paper mold of the utility model during normal operation, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0023] like Figures 1 to 7 As shown in the figure, a mechanical part marking paper model includes a paper model 1, which is a common writing paper or oil paper on which graphics can be printed, and the paper model 1 is printed with a part to be processed. Figure 2 ,Component Figure 2 The size of the part is in a 1:1 ratio to the actual part. A reference line 3 is drawn on the paper model 1. Figure 2 The turning points and intersections of the parts are all drawn with reference points 4; the blank 5 to be processed is also included, the blank 5 is completed by CNC nesting, and a reference line 2 6 is drawn on the nested blank 5, and the position of the reference line 2 6 corresponds to the reference line 1 3; when nesting, a larger hole needs to have a processing allowance of 3 to 5 mm; preferably, the reference line 1 3 and the reference line 2 6 are both cross-shaped, and when the part is a centrally symmetrical figure, the intersection of the reference lines is located at the part Figure 2 Or the center of the blank 5.

[0024] Furthermore, the shape of the part to be processed can be a centrally symmetrical figure, such as a circle, an ellipse, and an equilateral triangle. When the shape of the part to be processed is a centrally symmetrical figure, the center of the reference line 3 is located at the part. Figure 2 The center of the reference line 2 6 is located at the center of the blank 5.

[0025] Furthermore, the shape of the part to be processed can also be an asymmetric irregular shape. When the shape of the part to be processed is an asymmetric irregular shape, a representative intersection point or turning point on the part is selected as the center point of the baseline, and the baseline is drawn. The position selection on the paper model 1 and the blank 5 is kept consistent, and positioning is convenient.

[0026] In parts Figure 2 When setting the reference point 4 on the workpiece 5, it should be noted that the density of the reference point 4 depends on the shape of the part. A reference point 4 should be stamped at each turning point and intersection. The distance of the reference point 4 depends on the shape and length of the line. It can be sparse on a straight line and slightly dense on a curve. When stamping the reference point 4 on the blank 5, the depth of the reference point 4 needs to be determined according to the material and thickness of the part. The depth of the reference point 4 of a thin part should be shallower, the depth of the reference point 4 of a rough part can be deeper, the reference point 4 of a soft part should be drawn lightly, and the reference point 4 at the center of the hole is better to be larger so that the drill bit can easily align with the center of the circle when drilling.

[0027] When using this marking paper template to mark mechanical parts, follow the steps below:

[0028] (a) Draw the parts in a 1:1 ratio using computer graphics software Figure 2 ;

[0029] (b) In parts Figure 2 Draw a reference line 3 and a reference point 4;

[0030] (c) Print the part on paper model 1 at a 1:1 ratio Figure 2 ;

[0031] (d) CNC nesting is performed on the processed parts, and a reference line 2 6 is drawn on the nested blank 5, corresponding to the reference line 1 3 on the paper model 1;

[0032] (e) Lay the printed paper mold 1 flat on the blank 5 so that the reference line 1 3 on the paper mold 1 coincides with the reference line 2 6 on the blank 5, and use a pressure iron to completely fit and fix the paper mold 1 and the blank 5;

[0033] (f) Use the sample gun to remove the parts on the paper model 1 Figure 2 The reference point 4 is stamped onto the blank 5;

[0034] (g) Remove paper model 1 and compare the parts Figure 2 , connect the contour lines to be processed, draw the contour lines of the graphics to be machined, and the marking process is completed.

[0035] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
