[0024] In the related art, the saddle-shaped connector presents a complex saddle-shaped curved surface due to its structure, and its unique geometric shape makes it difficult to directly perform surfacing operation. During surfacing operation, in order to ensure the welding quality and stability, the curved surface to be surfaced on the saddle-shaped connector is usually precisely adjusted to a flat welding position by means of auxiliary tooling equipment to adapt to the requirements of the conventional surfacing process. However, since the curved surface of the saddle-shaped connector is not a single plane, in the actual surfacing process, the surfacing of the entire surface of the saddle-shaped connector cannot be completed by adjusting the tooling only once. This inevitably requires multiple re-adjustments of the auxiliary tooling and multiple overturning operations of the saddle-shaped connector to achieve surfacing coverage of the curved surfaces of different parts. Frequent overturning and tooling adjustment not only consumes a lot of time and manpower, but also seriously interferes with the continuity of the surfacing operation, and seriously affects the surfacing efficiency.

[0025] To solve the problems in the related art, the present embodiment provides a surfacing method and device for a saddle-shaped connector and an electronic device.

[0026] As shown in Figure 1 and 2 A surfacing method for a saddle-shaped connector provided by the present embodiment includes: S100, dividing the welding surface of the saddle surface according to the spatial structure into a first surfacing area and a second surfacing area, wherein the first surfacing area includes a saddle-shaped outer facade 1, a saddle-shaped inner wall 2, and a saddle-shaped fillet 3, and the second surfacing area includes a saddle-shaped end surface 4 and a saddle-shaped boss 5.

[0027] It should be noted that this automatic welding equipment features circumferential rotation and a welding gun lift adjustment function. The axial rotation can drive the welding gun to perform regular circular motion (e.g., 360° rotation) around the central axis, making it suitable for surfacing welding of rotationally symmetrical structures, such as the inner wall and regular end faces of a saddle-surface pipe 6. The welding gun lift adjustment function allows for precise vertical (height) movement of the welding gun to accommodate variations in the height of the surfacing surface (e.g., variations in the height of the saddle-shaped end face 4 and the saddle-shaped boss 5). This allows the automatic welding equipment, with both rotational and lift functions, to perform surfacing welding on different surfaces of the saddle-shaped pipe 6 to be welded. This avoids repeated adjustments to the position of the saddle-shaped pipe 6 during the surfacing process, improving surfacing efficiency.

[0028] Specifically, if Figure 2 As shown, based on the functional characteristics of the automatic welding equipment, the surface to be welded of the saddle-shaped nozzle 6 can be divided into a first surfacing area and a second surfacing area according to its spatial structural characteristics. The first surfacing area can include the saddle-shaped exterior surface 1, the saddle-shaped interior wall 2, and the saddle-shaped fillet 3. The welding trajectory of these areas is generally a trajectory curve; the second surfacing area can include the saddle-shaped end face 4 and the saddle-shaped boss 5. Due to the height difference between the end face and the boss, the height of the welding gun needs to be adjusted during the welding process to adapt to the height difference between these areas.

[0029] S200 , controlling the automatic welding equipment according to a preset first welding rule to perform surfacing welding on the saddle-shaped outer facade 1 , the saddle-shaped inner wall 2 , and the saddle-shaped fillet 3 .

[0030] Specifically, since the surfacing surfaces of the saddle-shaped outer facade 1, the saddle-shaped inner wall 2 and the saddle-shaped fillet 3 to be surfacing are not adjusted to flat welding, it is necessary to set the corresponding first welding rule for the vertical or inclined surfacing surface of the area to be welded, so that the surfacing surface of the first welding area can be surfacing welded by using the circumferential rotation function of the automatic welding equipment through the first welding rule. Figure 3 As shown, due to the structural characteristics of the first welding area, the welding trajectory of the area to be surfacing is a curved surface trajectory. Therefore, based on the principle of integration, the curved surface welding trajectory B of the area to be surfacing can be divided into multiple segments, and each segment A can be welded by controlling the automatic welding equipment. For example, in each segment, the welding gun is controlled to move an oblique line, so that the oblique lines formed by surfacing of all segments A can be approximated to form the required curved surface welding trajectory B. According to the accuracy requirements of surfacing, the more segments A are divided, the closer the surfacing result is to the required curved surface welding trajectory B.

[0031] S300 , controlling the automatic welding equipment to perform build-up welding on the saddle row end surface and the saddle-shaped boss 5 according to a preset second welding rule.

[0032] Specifically, since the surfacing surface of the saddle-shaped end face 4 and the saddle-shaped boss 5 in the area to be welded is in a flat welding position (horizontal position or near horizontal position), it is sufficient to control the welding gun to rotate one circle when performing surfacing welding. However, since there is a height difference between different positions of the saddle-shaped end face 4 and the saddle-shaped boss in the area to be welded, during the surfacing welding process, in addition to controlling the welding gun to perform circular motion, it is also necessary to continuously adjust the height of the welding gun during the welding process to adapt to the changes in the height difference of the area to be welded. Therefore, through the pre-set second welding rule, the automatic welding equipment is controlled to perform surfacing welding on the area to be welded of the saddle-shaped end face 4 and the saddle-shaped boss 5, so as to ensure that the height changes of the area to be welded can be adapted during the welding process, thereby improving the welding efficiency.

[0033] In this embodiment, the saddle surface to be welded is divided into a first surfacing area and a second surfacing area according to the spatial structure, and the preset first welding rule and second welding rule are used to control the automatic welding equipment to perform surfacing welding on the first surfacing area and the second surfacing area respectively. Since the spatial structure of the saddle-shaped facade 1, the saddle-shaped inner wall 2 and the saddle-shaped fillet 3 of the saddle-shaped pipe 6 is different from that of the saddle-shaped end face 4 and the saddle-shaped boss 5, the areas are divided separately and the corresponding welding rules are matched. The corresponding welding operation can be accurately set according to the characteristics of different areas to be welded. The surfacing welding of all the surfacing areas of the saddle-shaped pipe 6 can be completed without adjusting the positions of different welding areas, avoiding repeated adjustments to the position of the saddle-shaped pipe 6, saving manpower and time, and thus significantly improving the surfacing efficiency of the areas to be welded of the saddle-shaped pipe 6.

[0034] Optionally, the first welding rule includes a preset facade welding rule, an inner wall welding rule, and a fillet welding rule; controlling the automatic welding equipment according to the preset first welding rule to perform surfacing welding on the saddle-shaped facade 1, the saddle-shaped inner wall 2, and the saddle-shaped fillet 3 includes: Controlling the automatic welding equipment according to the facade welding rules to perform surfacing welding on the saddle-shaped facade 1; Controlling the automatic welding equipment according to the inner wall welding rule to perform surfacing welding on the saddle-shaped inner wall 2; The automatic welding equipment is controlled according to the fillet welding rule to perform build-up welding on the saddle-shaped fillet 3 .

[0035] In the optional embodiment, for the saddle-shaped outer facade 1, the corresponding outer facade welding rules can be set according to the welding track of the saddle-shaped outer facade 1, so as to control the automatic welding equipment to perform surfacing on the saddle-shaped outer facade 1 through the outer facade welding rules. Similarly, the corresponding inner wall welding rules can be set according to the welding track of the saddle-shaped inner wall 2, so as to control the automatic welding equipment to perform surfacing on the saddle-shaped inner wall 2 through the inner wall welding rules; the corresponding fillet welding rules can be set according to the welding track of the saddle-shaped fillet 3, so as to control the automatic welding equipment to perform surfacing on the saddle-shaped fillet 3 through the fillet welding rules. By formulating corresponding welding rules for different welding areas, the automatic welding equipment can be controlled to accurately and efficiently weld the saddle-shaped outer facade 1, the saddle-shaped inner wall 2 and the saddle-shaped fillet 3 through the welding gun, thereby effectively improving the surfacing quality and surfacing efficiency.

[0036] Optionally, the surfacing on the saddle-shaped outer facade 1 by the automatic welding equipment according to the outer facade welding rules comprises: obtaining the outer facade welding path length of the saddle-shaped outer facade 1; dividing the outer facade welding path length by a preset outer facade welding frequency to obtain an outer facade welding step; dividing the circumference by the outer facade welding frequency to obtain an outer facade welding angle of each welding rotation of the automatic welding equipment; controlling the automatic welding equipment to perform surfacing on the welding path of the saddle-shaped outer facade 1 according to the outer facade welding step and the outer facade welding angle.

[0037] In the optional embodiment, the length of the outer facade welding path of the saddle-shaped outer facade 1 is obtained, and the length is divided by the preset outer facade welding times to obtain the outer facade welding step length of each welding, which represents the length of the control of the welding gun walking diagonal line in the single welding process. At the same time, the circumference angle (360°) is divided by the outer facade welding times to obtain the angle of the welding gun rotation required to be controlled by the automatic welding equipment in each welding, that is, the outer facade welding angle (for example, when the welding times are 36 times, the angle of each rotation required is 10° by dividing 360° by 36). In the surfacing process, the automatic welding equipment controls the movement of the welding gun along the decomposed diagonal line trajectory according to the calculated outer facade welding step length, and the angle of the rotation of the welding gun after each movement is the outer facade welding angle, so that the welding gun rotates 360°, that is, rotates a circle, when it completes the outer facade welding times in turn. Through the diagonal welding (such as completing a welding to form a diagonal line by rotating 10° each time), the trajectory of 36 diagonal lines is accumulated to form the complete welding curve of the saddle-shaped outer facade 1, so as to realize the uniform surfacing of the saddle-shaped outer facade 1. By decomposing the complex welding curve of the saddle-shaped outer facade 1 into quantifiable straight line segments, the welding path is accurately controlled by the rotation of the automatic welding equipment and the lifting of the welding gun, so as to ensure the accuracy of the surfacing trajectory and the uniformity of the surfacing layer.

[0038] Optionally, the surfacing of the saddle-shaped inner wall 2 by the automatic welding equipment according to the inner wall welding rule comprises: obtaining the inner wall welding path length of the saddle-shaped inner wall 2; dividing the inner wall welding path length by the preset inner wall welding times to obtain the inner wall welding step length; dividing the circumference angle by the inner wall welding times to obtain the inner wall welding angle of the rotation of the automatic welding equipment in each welding; controlling the welding path of the automatic welding equipment for the surfacing of the saddle-shaped inner wall 2 according to the inner wall welding step length and the inner wall welding angle.

[0039] In the optional embodiment, after the length of the inner wall welding path of the saddle-shaped inner wall 2 is obtained, the length is divided by the preset inner wall welding times to obtain the inner wall welding step length of each welding, which represents the moving distance of the welding gun along the inner wall path direction in single welding; at the same time, the circumference angle (360°) is divided by the inner wall welding times to obtain the angle of the welding gun rotation that needs to be controlled by the automatic welding equipment in each welding, i.e. the inner wall welding angle (for example, if the welding times are N times, the angle of each rotation is 360° / N). In the surfacing process, the automatic welding equipment controls the welding gun to weld along the inner wall welding path according to the calculated inner wall welding step length, and controls the welding gun to rotate by the inner wall welding angle after each movement, so that the welding gun divides the complex inner wall curved surface track into a plurality of welding segments by means of step-by-step welding (such as completing a segment of welding by rotating a certain angle each time to obtain a welding diagonal line), thereby realizing welding of a diagonal line in the welding segment by rotating and lifting movement of the automatic welding equipment, so as to approximate the curve of the inner wall welding path by the diagonal lines of all welding segments, and finally complete the surfacing of the entire saddle-shaped inner wall 2.

[0040] Optionally, the surfacing of the saddle-shaped fillet 3 according to the control of the automatic welding equipment according to the fillet welding rule comprises: obtaining the fillet welding path length of the saddle-shaped fillet 3; dividing the fillet welding path length by the preset fillet welding times to obtain a fillet welding step length; dividing the circumference angle by the fillet welding times to obtain a fillet welding angle of each welding rotation of the automatic welding equipment; controlling the automatic welding equipment to weld the welding path of the saddle-shaped fillet 3 according to the fillet welding step length and the fillet welding angle.

[0041] In the optional embodiment, after the length of the fillet welding path of the saddle-shaped fillet 3 is obtained, the length is divided by the preset number of fillet weldings to obtain a fillet welding step length for each welding, which represents the moving distance of the welding torch in a single welding along the direction of the fillet path. At the same time, the circumference (360°) is divided by the number of fillet weldings to obtain the angle of rotation of the welding torch that needs to be controlled by the automatic welding equipment during each welding, i.e., the fillet welding angle (for example, if the number of weldings is M, the angle of rotation for each welding is 360° / M). During surfacing, the automatic welding equipment controls the welding torch to move along the small track obtained by decomposing the fillet to form a slant line with a length of the fillet welding compensation according to the calculated fillet welding step length, and controls the welding torch to rotate by the fillet welding angle each time, so that the welding torch completes the welding of the fillet segment by segment (for example, rotates by a certain angle each time, and finally rotates by 360°), thereby completing the slant line welding of each segment by controlling the rotation and lifting of the welding torch. By decomposing the complex curved track of the fillet into a plurality of quantifiable straight line segments, and using the automatic welding equipment to perform slant line welding, the cumulative total of the segmented slant lines is approximately formed into a welding curve of the fillet welding path, which can not only accurately control the shape and size of the molten pool, but also ensure the surfacing effect of the surfacing layer at the fillet through the cooperative control of the angle and the step length, thereby avoiding surfacing defects caused by the inability of the equipment to directly perform curved motion, and effectively improving the quality and efficiency of the fillet surfacing.

[0042] Optionally, the second welding rule includes a preset end face welding rule and a boss welding rule; and the controlling the automatic welding equipment to perform surfacing on the saddle-shaped end face and the saddle-shaped boss 5 according to the preset second welding rule includes: controlling the automatic welding equipment to perform surfacing on the saddle-shaped end face 4 according to the end face welding rule; controlling the automatic welding equipment to perform surfacing on the saddle-shaped boss 5 according to the boss welding rule.

[0043] In the optional embodiment, for the saddle-shaped end face 4, a corresponding end face welding rule is set according to the planar structure characteristics of the end face, so that the automatic welding equipment is controlled to perform surfacing on the saddle-shaped end face 4 through the end face welding rule. Since the plane of the saddle-shaped end face 4 is circular, a ring-shaped welding path can be used for welding, and the welding torch can be controlled to rotate one round for surfacing. However, since there is a height difference in the plane of the end face, the change in height needs to be considered when setting the welding rule, so that the surfacing can completely fit the surface of the end face. Similarly, since the planar structure of the saddle-shaped boss 5 is similar to that of the saddle-shaped end face 4, a corresponding boss welding rule is set according to the planar structure, and the boss welding rule also needs to consider the change in height during welding. Through the corresponding welding rule, the automatic welding equipment is accurately controlled to perform surfacing on the saddle-shaped end face 4 and the saddle-shaped boss 5, thereby meeting the demand of the welding track of different surfacing surfaces and efficiently and accurately completing the surfacing of the surfacing surface.

[0044] Optionally, the controlling the automatic welding device according to the end face welding rule to perform surfacing welding on the saddle-shaped end face 4 comprises: obtaining an end face welding height difference and an end face welding path angle of an end face welding path of the saddle-shaped end face 4, wherein the end face welding path is divided according to the ascending section and the descending section of the saddle-shaped end face 4; dividing the end face welding path height difference by a preset end face welding number to obtain an end face welding height, and dividing the end face welding path angle by the end face welding number to obtain an end face welding angle; controlling the automatic welding device according to the end face welding height and the end face welding angle to perform surfacing welding on the welding path of the saddle-shaped end face 4.

[0045] It should be noted that the saddle-shaped end face 4 generally presents ups and downs, and the welding torch also experiences ups and downs during one rotation of the welding process. Therefore, when setting the welding rule, the circumferential welding path can be divided into a single gradually ascending end welding path and a gradually descending welding path, that is, one circumferential welding path can be decomposed into multiple end face welding paths, including a gradually ascending welding path and a gradually descending welding path.

[0046] In this optional embodiment, the end face welding path height difference (i.e. the ascending height difference of the gradually ascending welding path or the descending height difference of the gradually descending welding path) and the path angle (i.e. the angle at which the gradually ascending welding path or the gradually descending welding path requires the welding torch to rotate) of the saddle-shaped end face 4 are obtained, the end face welding path height difference is divided by a preset end face welding number to obtain the end face welding height of each welding (i.e. the change amount of the vertical height increase or decrease of single welding), and the path angle is divided by the number to obtain the end face welding angle of each welding, that is, the angle at which the welding torch is controlled to rotate during each welding. During the surfacing welding process, the automatic welding device controls the welding torch to be lifted or lowered along the vertical direction of the end face according to the end face welding height, and controls the rotation of the welding torch according to the end face welding angle, so that the welding torch performs surfacing welding along the end face welding path. For example, if the end face welding number is N times, the welding torch rotates by a certain angle according to the end face welding angle during each welding, and the vertical position is adjusted by lifting or lowering the welding torch according to the end face welding height, and N welding cycles are completed in turn, so that the surfacing welding of the end face welding path is completed. By quantitatively decomposing the welding path, the automatic welding device can be accurately controlled to perform surfacing welding according to the set end face welding rule, so that the surfacing welding accuracy and efficiency of the saddle-shaped end face 4 can be significantly improved.

[0047] Optionally, the controlling the automatic welding device according to the boss welding rule to perform surfacing welding on the saddle-shaped boss 5 comprises: obtaining a boss welding path height difference and a boss welding path angle of the boss welding path of the saddle-shaped boss 5, wherein the boss welding path is divided according to the rising section and the falling section of the saddle-shaped boss 5; dividing the boss welding path height difference by a preset boss welding number to obtain a boss welding height, and dividing the boss welding path angle by the boss welding number to obtain a boss welding angle; controlling the automatic welding equipment according to the boss welding height and the boss welding angle to perform the surfacing on the boss welding path of the saddle-shaped boss 5.

[0048] In the optional embodiment, the planar structure of the saddle-shaped boss 5 is similar to the saddle-shaped end face 4, and thus the surfacing process of the saddle-shaped boss 5 is similar to the surfacing process of the saddle-shaped end face 4. After obtaining the boss welding path height difference and the path angle, the height difference is divided by the preset boss welding number to obtain the boss welding height of each welding, and the path angle is divided by the welding number to obtain the welding angle, that is, the boss welding angle, which controls the rotation angle of the welding gun. In the surfacing process, the automatic welding equipment controls the welding gun to ascend or descend along the vertical direction of the boss according to the boss welding height, and controls the welding gun to rotate according to the boss welding angle, so that the welding gun performs the surfacing along the boss welding path. By quantitatively decomposing the welding path, the automatic welding equipment can be accurately controlled to perform the surfacing according to the set boss welding rule, so that the surfacing precision and efficiency of the saddle-shaped boss 5 can be significantly improved.

[0049] As shown in Figure 4 The surfacing device for the saddle-shaped connector pipe provided by the embodiment of the present application comprises: The processing module 410 is configured to divide the to-be-welded surface of the saddle surface into a first surfacing area and a second surfacing area according to the spatial structure, wherein the first surfacing area comprises a saddle-shaped outer vertical surface, a saddle-shaped inner wall and a saddle-shaped fillet, and the second surfacing area comprises a saddle-shaped end face and a saddle-shaped boss. The first control module 420 is configured to control the automatic welding equipment to perform the surfacing on the saddle-shaped outer vertical surface, the saddle-shaped inner wall and the saddle-shaped fillet according to a preset first welding rule.
