[0073] The sample parts are prepared with reference to the theoretical outline of the porous parts and the theoretical hole centers of m holes;

[0074] Weld the sample parts and obtain the experimental parts after cooling;

[0075] Measure the boundary offset between the sample part and the test part;

[0076] Based on the theoretical contour of the porous part and combined with the boundary offset, the adjusted contour of the porous part is obtained.

[0077] In one embodiment, the boundary offset includes an X-axis offset and a Y-axis offset.

[0078] In one embodiment, taking the theoretical contour of the porous part as a reference and combining the boundary offset, obtaining the adjusted contour of the porous part includes the following steps:

[0079] In the theoretical contour of the porous part, multiple boundary theoretical hole positions are selected as first reference holes, wherein the boundary theoretical hole position center is the theoretical hole position center closest to the boundary of the theoretical contour of the porous part, and the distance between the boundary theoretical hole position center and the boundary of the theoretical contour of the porous part is a preset value;

[0080] Taking the XY coordinates of the centers of the theoretical holes of the multiple boundaries as references and combining them with their corresponding boundary offsets, multiple boundary adjustment hole centers are obtained;

[0081] The adjustment contour of the porous part is obtained by taking the centers of the hole positions adjusted by multiple boundaries as the reference and combining the preset values.

[0082] The following is a specific embodiment provided by this application:

[0083] by Figure 2 A thin plate part (porous part) of an engine is shown as an example for explanation. The outline of the porous part is fan-shaped. There are multiple small holes with a diameter of φD (D ranges from 0.5-1.5mm) distributed on the porous part according to a certain rule. The number of holes is about 5000-15000, and the thickness is δ. For ease of understanding and clear expression of the drawings, a smaller number of holes is used for illustration in the attached drawings.

[0084] (1) First, prepare the sample part with reference to the theoretical outline of the porous part and the theoretical hole centers of m (5000-15000) holes; for the porous part, Figure 3The four boundary theoretical hole positions shown ("hole 1", "hole 2", "hole 3", "hole 4") and the theoretical contour of the porous part (solid line segments in the figure, including the first boundary 1, the second boundary 2, the third boundary 3 and the fourth boundary 4 respectively) must satisfy the following relationship: the distance dimension from the axis of "hole 2" to the first boundary 1 is V2, the distance dimension from the axis of "hole 1" to the second boundary 2 is V1, the distance dimension from the axis of "hole 1" to the fourth boundary 4 is H1; the distance dimension from the axis of "hole 2" to the fourth boundary 4 is H2; "hole 3" and "hole 1" are symmetrical relative to the midline, and "hole 4" and "hole 2" are symmetrical relative to the midline. The remaining small holes are distributed according to a certain rule within the dotted line range of "hole 1", "hole 2", "hole 3", and "hole 4".

[0085] (2) Weld the sample parts and obtain the experimental parts after cooling; specifically, overlap the two sample parts, put the solder on the contact surface in advance, heat them to a certain temperature in a diffusion welding furnace, and under a certain pressure, diffusion connection occurs on the contact surface of the two sample parts to complete the welding process. After welding, cool and obtain the experimental parts. Contour comparison of the sample parts and the experimental parts Figure 4 As shown, the contour boundary shown by the solid line in the figure is the contour boundary of the sample part, and the contour boundary shown by the dotted line in the figure is the contour boundary of the experimental part. It can be found that, relative to the sample part, the contour boundary of the experimental part obtained after cooling during welding heat treatment shrinks.

[0086] (3) Measure the boundary offset between the sample part and the experimental part; specifically, take the "zero point" as the measurement reference, and the "zero point" of the experimental part coincides with the "zero point" of the sample part. The X-direction offset of "Point 1" is represented by "X1", and the Y-direction offset is represented by "Y1". The X-direction offset difference of "Point 2" is represented by "X2", and the Y-direction offset is represented by "Y2". "Point 3" is a symmetrical point relative to "Point 1", and "Point 4" is a symmetrical point relative to "Point 2". The dimensional deviation of "Point 5" is represented only by the Y-direction offset "Y5". Measure the values ​​of X1, Y1, X2, Y2 and Y5 respectively to obtain the boundary offset.

[0087] (4) Taking the theoretical contour of the porous part as a reference and combining the boundary offset, the adjusted contour of the porous part is obtained, which specifically includes the following steps:

[0088] (4-1) In the theoretical contour of the porous part, multiple boundary theoretical hole positions (i.e., "hole 1", "hole 2", "hole 3", "hole 4") are selected as the first reference hole positions, wherein the boundary theoretical hole position center is the theoretical hole position center closest to the boundary of the theoretical contour of the porous part, and the distance between the boundary theoretical hole position center and the boundary of the theoretical contour of the porous part is a preset value (i.e., V1, V2, H1, H2).

[0089] (4-2) Taking the XY coordinates of the centers of the theoretical holes at the boundaries as the reference, respectively combine the corresponding boundary offsets (i.e., X1, Y1, X2, Y2, and Y5), that is, add the X coordinate of the corresponding hole center to its X-direction offset, and add the Y coordinate of the corresponding hole center to its Y-direction offset, to obtain the XY coordinates of the centers of the adjusted holes at the boundaries;

[0090] (4-3) Taking the positions of the centers of the hole positions for boundary adjustment as the reference and combining the preset values ​​(i.e., V1, V2, H1, H2), the adjusted contour of the porous part is obtained. That is, taking the XY coordinates of the center of the hole position for boundary adjustment as the reference and offsetting the corresponding preset values, the coordinates of the vertices of the adjusted contour of the porous part can be determined, and then combined with the curvature shape of each boundary of the theoretical contour of the porous part, the XY coordinates of the center of the hole position for boundary adjustment are used as the basis for proportional offset to obtain the boundary of the adjusted contour of the porous part, and finally the adjusted contour of the porous part is obtained. The final adjusted contour of the porous part is as follows: Figure 5 As shown (the boundary of the adjusted contour of the porous part is the solid line segment shown in the figure).

[0091] (5) Figure 5 The theoretical contour of the porous part shown in FIG. 5 , a theoretical boundary vertex (any one of multiple vertices) of the theoretical contour of the porous part is selected as the first reference point 5;

[0092] (6) Taking the first reference point 5 as a reference, determining the relative position relationship between the nth theoretical hole center of the porous part (point n is taken as an example in the figure) and the first reference point 5, wherein n is a positive integer and 1≤n≤m; specifically, the following steps are included (the operations in this step are all performed in the theoretical contour of the porous part):

[0093] (6-1) A first equal reference curve LX is drawn through the center of the nth theoretical hole position, and the first equal reference curve LX intersects the first boundary 1 at a first intersection point (point A);

[0094] (6-2) Draw a second isoreference curve LY of the third boundary 3 and the fourth boundary 4 through the center of the nth theoretical hole position, and the second isoreference curve LY intersects the third boundary 3 at a second intersection point (point B);

[0095] (6-3) Determine a first length ratio a of the first intersection relative to the first reference point 5 on the first boundary 1, and determine a second length ratio b of the second intersection relative to the first reference point 5 on the third boundary 3; specifically, the first length ratio a=La / LA, where La is the length of the first intersection relative to the first reference point along the length direction of the first boundary, and LA is the total length of the first boundary. The second length ratio b=Lb / LB, where Lb is the length of the second intersection relative to the first reference point along the length direction of the third boundary, and LB is the total length of the third boundary.

[0096] (6-4) The relative position relationship is determined by the first length ratio a and the second length ratio b.

[0097] (7) Figure 6 As shown, the adjusted boundary vertex corresponding to the theoretical boundary vertex and the adjusted contour of the porous part is used as the second reference point 6;

[0098] (8) Taking the second reference point 6 as a reference and combining the relative position relationship, determining the nth adjustment hole center of the porous part; specifically comprising the following steps:

[0099] (8-1) Taking the second reference point 6 as a reference and according to the first length ratio a, determine the first positioning point (point A') on the first boundary 1; that is, control La'=aLA', where La' is the length of the first positioning point relative to the second reference point 6 along the length direction of the first boundary 1, and LA' is the total length of the first boundary.

[0100] (8-2) Taking the second reference point 6 as a reference and according to the second length ratio b, determine the second positioning point (point B') on the third boundary 3; that is, control Lb'=bLB', where La' is the length of the second positioning point relative to the second reference point 6 along the length direction of the third boundary 3, and LB' is the total length of the third boundary 3.

[0101] (8-3) drawing a third isoreference curve LX' of the first boundary 1 and the second boundary 2 through the first positioning point, and drawing a fourth isoreference curve LY' of the third boundary 3 and the fourth boundary 4 through the second positioning point;

[0102] (8-4) The intersection of the third reference curve LX' and the fourth reference curve LY' is the center of the nth adjustment hole position (with Figure 6 Take point N as an example, point N is the adjusted point corresponding to point n).

[0103] (9) Starting from n=1, repeat the above steps (8-2) to (8-4), and n increases by 1 in each repetition until n=m. For example, when the porous part has 5000 holes, that is, m=5000, it starts from n=1, and n increases by 1 in each repetition until n=5000, and the positioning of 5000 holes is completed, and the adjusted porous part adjustment contour and the positions corresponding to the m holes are obtained. Specifically, a script can be designed by programming, and the script can run a loop calculation algorithm. The script is run in the corresponding design software to repeat this step until all points are automatically adjusted, which significantly improves the design efficiency. The specific computer program and its design principle involved in the script are the prior art known to those skilled in the art, and this application will not be repeated. When the corresponding computer program is used to run the hole position adjustment method of the porous part provided in this embodiment, after the part contour is adjusted, the hole positions of all small holes can be automatically arranged, which improves the efficiency of small hole arrangement design and shortens the development cycle of the porous part.

[0104] After the operation is completed, the adjusted contour of the porous part and its hole position are obtained, such as Figure 7 As shown, Figure 7 It is a schematic diagram comparing the theoretical contour 7 of a porous part and the theoretical hole center 9 therein, and the adjusted contour 8 of a porous part and the adjusted hole center 10 therein.

[0105] (10) Cutting parts with the adjusted contour of the porous part obtained in step (9), and punching holes according to the positions corresponding to the m holes to obtain the adjusted sample parts, welding the adjusted sample parts, and obtaining the adjusted experimental parts after cooling. The preparation process of the adjusted experimental parts is the same as the above step (2). Then measure the contour deviation value of the adjusted experimental part relative to the theoretical contour of the porous part, as well as the deviation value of each hole position. If the deviation value meets the design requirements, the parts are manufactured and mass-produced according to the corresponding porous part adjustment contour and hole position. As long as the contour size and welding process parameters of the parts are consistent, the outer contour size changes of the porous parts after mass production are basically consistent. If the deviation value does not meet the design requirements, repeat steps (4) to (9) again, and use a deviation value different from the last adjustment to adjust the porous part adjustment contour again until the deviation value meets the design requirements.
