[0037] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0040] In the description of the present invention, it should be further noted that the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0041] The present invention discloses a detection method, device, equipment and application scenarios of products for a stud welding surface as Figure 1As shown, under the existing technical conditions, the quality inspection of the welding surface in the product model is usually carried out manually one by one, which has the problems of frequent missed inspections and misjudgments, large and cumbersome operation volume, and low inspection efficiency. For example, the welding surface of standard parts such as welded stud bolts in the body-in-white assembly must be a plane, and the size of the plane needs to meet the welding space requirements. Therefore, when designers carry out structural design, they need to detect the flatness and size of the welding surface on the product model to ensure that the welding requirements can be met later. However, there are hundreds of stud bolt welding points on the body-in-white product model, and it is laborious and cumbersome to manually detect whether the stud welding surface on the product model meets the design requirements.

[0042] The present invention discloses a method, device, equipment and product for detecting a stud welding surface. According to the intersection situation of the stud and the part, it is judged whether the quality of the stud welding surface is qualified; a cylinder intersecting with the part surface is established, a dividing surface for characterizing the state of the stud welding surface is obtained, and based on the dividing surface situation, compared with the preset standard, it is judged whether the quality of the stud welding surface is qualified. The present invention discloses a method, device, equipment and product for detecting a stud welding surface, which has multiple inspection dimensions, accurate detection results, and is very suitable for batch automatic detection of product models that need to detect the welding surface.

[0043] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0044] In an embodiment of the present invention, as Figure 2 shown, a method, device, equipment and product for detecting a stud welding surface disclosed by the present invention include:

[0045] Step S201, if the stud whose welding surface needs to be detected intersects with two or more parts, the quality of the stud welding surface is unqualified;

[0046] In this embodiment, the model whose stud welding surface needs to be detected is opened by using CATIA software, and the number of parts intersecting with the stud whose welding surface needs to be detected is obtained.

[0047] In another embodiment, CATIA software can also be replaced by SolidWorks, UG, Pro / ENGINEER, etc., as long as it can implement the content disclosed by the present invention.

[0048] In this embodiment, using the collision detection function of CATIA software, the intersection type is selected between two parts, product 1 is selected as the stud whose welding surface needs to be detected, and product 2 is selected as the product model to obtain the number of parts intersecting with the stud whose welding surface needs to be detected.

[0049] Step S202, as Figure 3As shown, if the stud to be detected on the welding surface intersects with only one part, extract the part surface of the intersecting part; if the axis of the stud is not perpendicular to the part surface, the quality of the stud welding surface is unqualified;

[0050] Step S203, as Figure 4 shown, if the axis of the stud is perpendicular to the part surface, with the axis as the center and a preset value as the diameter, establish a cylinder intersecting with the part surface;

[0051] Exemplarily, the preset value is 16 mm.

[0052] In this embodiment, using CATIA software, identify the axis of the stud, take the axis as the center line, and stretch a cylinder with the preset value as the diameter to intersect with the part surface;

[0053] In this embodiment, the preset value is used to set the detection diameter.

[0054] Step S204, determine that the part surface corresponding to the inside of the cylinder is the dividing surface used to characterize the state of the stud welding surface. If the dividing surface meets the preset standard, the quality of the stud welding surface is qualified; if the dividing surface does not meet the preset standard, the quality of the stud welding surface is unqualified.

[0055] As Figure 4 shown, the dividing surface is the part surface corresponding to the inside of the cylinder.

[0056] Furthermore, this method further includes: outputting a file including the detection results of all welding surfaces to be detected.

[0057] In this embodiment, exemplarily, the format of the file can be an EXCEL file or other file formats that can achieve the same function.

[0058] Based on the EXCEL file, output the detection results of all welding surfaces to be detected.

[0059] In this embodiment, the detection results recorded in the EXCEL file can be manually corrected.

[0060] On the basis of the previous embodiment, in another embodiment of the present invention, as Figure 2 shown, in step S204, if the dividing surface meets the preset standard, the quality of the stud welding surface is qualified; if the dividing surface does not meet the preset standard, the quality of the stud welding surface is unqualified, and it further includes: using the disassembly function of CATIA software to determine the number of units included in the dividing surface;

[0061] In this embodiment, the number of units included in the dividing surface refers to how many independent surfaces the dividing surface consists of. A qualified stud welding surface needs to have only one surface, that is, only one unit.

[0062] If the splitting plane contains only one cell, and the splitting plane is a plane, and the boundary of the splitting plane is circular, then the quality of the stud welding surface is qualified;

[0063] If the splitting plane does not simultaneously meet the three conditions of containing only one cell, being a plane, and having a circular boundary, then the quality of the stud welding surface is unqualified.

[0064] In this embodiment, by way of example:

[0065] If the splitting plane contains only one cell and the splitting plane is not a plane, then the inspection of the stud welding surface is unqualified;

[0066] If the splitting plane contains only one cell, and the splitting plane is a plane, and the boundary of the splitting plane is not circular, then the inspection of the stud welding surface is unqualified;

[0067] If the splitting plane contains two or more cells, then the inspection of the stud welding surface is unqualified;

[0068] In this embodiment, by comprehensively detecting whether the number of cells contained in the splitting plane, whether the splitting plane is a plane, and the shape of the boundary of the splitting plane, it is determined whether the quality of the stud welding surface is qualified, which has the characteristics of multiple detection dimensions and accurate detection results.

[0069] In another embodiment of the present invention, the measurement function of CATIA software is used to determine whether the splitting plane is a plane.

[0070] In another embodiment of the present invention, as Figure 5 and Figure 6 shown, the extraction function of CATIA software is used to determine whether the boundary of the splitting plane is circular, and the extended type in the extraction definition is selected as no extension.

[0071] Using the measurement function and extraction function of CATIA software can improve the detection efficiency and is suitable for batch automatic detection of the welding surfaces that need to be detected in the product model.

[0072] In an embodiment of the present invention, the implementation process of the above method through software is as follows, including:

[0073] After entering the flatness detection interface of the welding surface, click "Select Product Model", and select the product model that needs to be detected for the welding surface in the CATIA interface;

[0074] The preset values of the detected product model are displayed on the software interface, and the user can modify them;

[0075] After clicking the "Surface Review" button, the software retrieves one by one according to the stud identification set in the database in the CATIA selected product model to identify the studs corresponding to the characters;

[0076] The welding surface is inspected;

[0077] When the user clicks on a line of data in the list, the data in CATIA interacts with it, the corresponding stud position is displayed, and the drawing is highlighted and "centered".

[0078] After the results of the welding surface are output, the user can manually verify them. The inspection results can be changed by clicking the "Result Correction" button. After clicking, a software pop-up window will prompt "Do you want to correct the results" as a secondary verification to prevent incorrect modification;

[0079] Click the "Clear Data" function button to batch delete the inspection results;

[0080] Click the "Report Export" button, and the comprehensive result information of the welding surface inspection will be added to an EXCEL file, and this EXCEL file will be opened. The user can download it to a custom path.

[0081] The software sets up a platform interface. The platform interface is connected to the data interface of the CATIA software, and the inspection data of the CATIA software is read and processed through the method of CATIA API.
