[0053] Please refer to Figure 1 , this application provides a rapid design method for a welding assembly fixture, including the following steps:

[0054] Step S100, determining the fixture type of the target welding fixture;

[0055] Step S200: Obtain a number of workpiece templates according to the fixture type; the workpieces corresponding to the number of workpiece templates are used to form the target welding fixture;

[0056] Step S300: Obtain the parameter information input by the user, where the parameter information is used to define the dimensional information and positional relationship of a number of the workpieces;

[0057] Step S400: Automatically calculate and design a gusset plate model according to the parameter information and the gusset plate size influence relationship formula, where the gusset plate model is used to connect a number of the workpieces;

[0058] Step S500: Automatically assemble the gusset plate model and a number of the workpieces to obtain the target welding fixture.

[0059] Welding assembly fixtures are generally divided into single support pressing units, double cylinder clamping units, pure support units, double support pressing units, pure positioning pin and hook pin units, pure pressing units, telescopic structure units, etc. Therefore, in this embodiment, the fixture type corresponds to any of the above pressing units.

[0060] In the design, each pressing unit contains multiple styles, and the fixture design process for each unit is different. To design these clamping units, developers need to be familiar with the welding fixture design process, which is generally beyond the reach of ordinary developers.

[0061] At the same time, during the design process of each pressing unit, the gusset plate plays a role in connecting each semi-standard part and finished component, and its shape is not fixed, making it relatively troublesome to design.

[0062] In this embodiment, after sorting out the structures of various pressing units, summarize the dimensional requirements of the gusset plate for each pressing unit, and the influence of the distance between the gusset plate and other semi-standard parts and finished parts. Design an initial gusset plate model for each pressing unit, and substitute the gusset plate size and other internal parameters of the pressing unit into the dimensional requirements and influence relationship formula of the gusset plate, so as to judge whether the parameter information input in the pressing unit conforms to the dimensional relationship of the gusset plate model, and thus automatically calculate and design the gusset plate model when the parameters are appropriate.

[0063] This embodiment discloses a rapid design method for welding assembly jigs. When applied, it can determine the workpiece templates corresponding to the workpieces required by the target welding jig according to the jig type of the target welding jig. And determine the riser models corresponding to the risers for connecting each workpiece according to the user input parameters and each workpiece template. And it can automatically assemble the designed risers and each workpiece to obtain the final target welding jig. In this way, it can greatly reduce the software operation workload of designers, improve the design efficiency of jigs, and reduce the jig design cost. Enable designers to use standardized models or semi-standardized models to quickly complete the design and automatic assembly process of a clamping unit, greatly shortening the design cycle.

[0064] In an exemplary embodiment of the present disclosure, the generating the riser model according to the parameter information and the riser size influence relationship includes:

[0065] Obtain the initial template of the riser model;

[0066] Generate the riser model according to the initial template, the parameter information and the riser size influence relationship.

[0067] Among them, in actual application, the initial model may not only include the model of the riser, but also include other workpiece models. At the same time, since there are multiple styles for different pressing units, multiple common styles can be stored in advance. In each style, it includes the standard dimensions (initial dimensions) and positional relationships of the riser and each workpiece. However, it can be understood that due to different actual application scenarios, when designing the pressing unit, it is usually necessary to limit the workpiece dimensions and positional relationships, etc., so it is necessary for the user to input parameter information. These parameter information will affect the dimension information and positional relationships of several of the workpieces. Therefore, at this time, it is necessary to determine whether a riser can be generated under the limitation of the parameter information through the riser size influence relationship, and if possible, automatically calculate the template of the generated riser.

[0068] Specifically, the generating the riser model according to the initial template, the parameter information and the riser size influence relationship includes:

[0069] Substitute the initial template, the dimension information of several of the workpieces and the positional relationship into the riser size influence relationship to determine whether there will be interference between several of the workpieces;

[0070] If interference occurs, output a first prompt message; the first prompt message includes information indicating that the riser generation fails and a prompt message for the modification plan;

[0071] If no interference occurs, generate the riser model.

[0072] In the actual application process, taking a single clamping unit as an example, the parameter information needs to include the information in the following table, and a corresponding actual application method is provided:

[0073]

[0074]

[0075] To complete the sequential loading of each workpiece and component of the single support clamping unit into the user-specified position, the following several modules are required for support.

[0076] Programming language and compilation platform

[0077] C# language, and call the standard secondary development interface file (vb) provided by CATIA;

[0078] The program compilation tool is visual studio2018.

[0079] CATIA version, currently specified as R19SP5 64-bit.

[0080] Model file copy, move, delete template

[0081] Responsible for copying the required part or assembly model from the public disk or program package of the server to the device folder selected by the user according to the need, and creating, renaming, and deleting folders according to the need.

[0082] CATIA model feature record file and modification module

[0083] An xml file used to create or modify the center lines, points, planes and other features of parametric models, standard parts, standard components, etc. This xml needs to be maintained regularly.

[0084] CATIA model feature record xml reading module

[0085] When the program loads the model to create assembly constraints, this xml file is used for the program to read the file path of the model to be loaded and the model feature information required to create assembly constraints.

[0086] Various basic function templates

[0087] Include frequently called function methods, such as: point-to-plane distance calculation method, basic method for creating assembly constraints, three-dimensional vector calculation method, two-dimensional vector calculation method, unit direction determination method, etc. As long as they are basic methods frequently used by each clamping unit, they can be encapsulated as general function methods in the way of reserving parameters for the assembly modules of each clamping unit to call. Examples of basic function methods are as follows:

[0088] The following is the basic function for measuring the length from the measurement positioning point to the BASE surface.

[0089]

[0090] When the designer designs the clamping unit, the input parameters need to be verified in two aspects to ensure that the pressing unit can be generated normally and the corresponding riser design can be generated:

[0091] 1. According to the actual situation of the clamping unit, each parameter itself has a set parameter value range, and the parameter value input by the user needs to be judged and reminded of the range.

[0092] 2. Although the multiple input parameters themselves meet the range judgment, the combination of multiple parameters may not conform to the tooling structure. It is necessary to summarize whether the relationship between the parameters meets the structural requirements and the tooling design requirements according to the structural characteristics and actual needs of each unit. When it does not meet, prompt according to the actual situation to help the tooling designer input the tooling parameters more accurately, obtain satisfactory tooling parameters, and complete the rapid design of the clamping unit.

[0093] The following takes a single example for illustration:

[0094] The influence of the riser size and the position of the pin seat is as follows:

[0095] The initial height of the pin seat model is 65mm, and the width of the pin seat remains a fixed value.

[0096] The following two situations usually occur during the design:

[0097] Situation 1

[0098] The positioning point height is relatively high. After the pin seat is assembled at the initial height of 65mm, it is judged that if the upper surface of the connecting block is above the set position, then install it according to the upper surface of the connecting block at the set position, and the height of the pin seat adapts to this fixed height installation position, and the width direction is at the corresponding position on the riser.

[0099] Situation 2

[0100] The positioning point height is relatively low. After the pin seat is assembled at the initial height of 65mm, it is judged that if the upper surface of the connecting block is below the set position, then the height of the pin seat remains 65mm unchanged, the installation height adapts to the positioning point height, and the width direction is at the corresponding position on the riser.

[0101] In actual implementation, sort out these dimensional relationships and position influences item by item, and transform these relationships and position influences into conditional judgment calculation formulas item by item. When the requirements are not met, pop up a prompt that a specific relationship does not conform, so as to achieve the purpose of controlling the design of the riser.

[0102] The following gives an example of parameter sorting:

[0103] Please refer toFigure 2 (Instance reference view Figure 1 ), actually, it is required that the two points extending the two points Pt4 and Pt5 on the left side of the style connection block part should not appear outside the range of the vertical plate.

[0104] Note: Figure 2 The descriptions of the parameters are as follows in the table:

[0105]

[0106]

[0107]

[0108] The conversion relationship of the parameter formula (the influence relationship of the vertical plate size) is as follows:

[0109] Design requirement 1: The extended style connection block is 20 cm below the upper surface of the vertical plate:

[0110] That is, the upper surface of the vertical plate is more than 20 cm higher than the height of Pt4:

[0111] (OP1 - B1 - T0) - (OP2 - L1 + PB_h1 - PB_h2) ≥ 20,

[0112] After eliminating the fixed value: OP1 - B1 - OP2 + L1 ≥ 21

[0113] If the above relationship is not met, prompt the user that the design requirement is not met and how to adjust the parameters, as follows:

[0114] The extended style connection block is 20 cm below the upper surface of the vertical plate, and the vertical plate cannot be generated!

[0115] It can be solved by the following adjustment methods:

[0116] Reduce the height B1 of the support block;

[0117] Select a longer positioning pin L1;

[0118] Design requirement 2: The extended style connection block is above the corner seat:

[0119] That is, Pt5 is higher than the top surface of the corner seat, and the formula is:

[0120] (OP2 - L1 + PB_h1 - PB_h2 - B_H) - D ≥ 0

[0121] After eliminating the fixed value: OP2 - L1 - D ≥ 67

[0122] If the above relationship is not met, prompt the user that the design requirement is not met and how to adjust the parameters, as follows:

[0123] The upper end surface of the angle seat is higher than the upper end surface of the vertical board, and the vertical board cannot be generated!

[0124] This can be solved by adjusting the following method:

[0125] Select a shorter positioning pin L1;

[0126] Choose the lower angle seat model D;

[0127] Design requirement 3: The chamfer position on the left side of the vertical plate is automatically set according to the position of the extended style connection block:

[0128] That is, the horizontal or vertical distance between the position of Pt5 and the chamfered edge of the vertical plate is a fixed value of 5, and the chamfer value Lt is calculated. Under the premise of meeting the above two conditions, there are two cases:

[0129] Pt5 is on the right side of the left side of the corner seat, such as Figure 3 (See the example video Figure 2 ):

[0130] The formula is:

[0131] Lt1≥5, and Lt2≥0

[0132] That is: Ltx = P1P3-D_L-C, Lty = OP1-B1-T0-D-5

[0133] Lt=min(Ltx,Lty)

[0134] Pt5 is on the left side of the left side of the corner seat, such as Figure 4 (See the example video Figure 3 ):

[0135] The formula is: Lt=Ltx+Lty, that is

[0136] Lt=(P1P3-P2P3-PB_h3-T0-B_L)+(OP2-L1+PB_h1-PB_h2-B_H-D)

[0137] Substitute this into the calculation to get Lt.

[0138] In the above-mentioned working formulas, various parameters can be obtained by calling the CATIA interface to calculate the point-to-surface distance; or by corresponding different specifications with different size values; or by setting certain model parameters that do not require parametric updating as fixed values, and then respectively entering them into the formula to obtain the parameters Lt required by the program, and driving the program to perform chamfering operations on the vertical plate.

[0139] In an exemplary embodiment of the present disclosure, after obtaining the parameter information input by the user, the method further includes:

[0140] Determine whether each parameter in the parameter information is reasonable;

[0141] If it is unreasonable, the second prompt message is output;

[0142] The second prompt message includes information on the reason for the unreasonable parameter.

[0143] In actual application, not only should it be considered whether the vertical plate can be generated, but also it is necessary to consider whether interference will occur between the workpieces due to the limitations in the parameter information, resulting in the abnormal generation of the target welding fixture. Therefore, in this embodiment, the parameter information is also analyzed to determine whether each parameter is reasonable, and the second prompt message is output to remind the designer in the case of unreasonableness.

[0144] In this embodiment, taking the double-support pressing structure as an example, it is possible to confirm whether the parameters are reasonable through the following table.

[0145] Support Block 1 Support Block 2 Pressing Block 1 Pressing Block 2 Minimum Spacing between Two Positioning Points Minimum Spacing Value Specified by the Program Not Flipped Not Flipped Not Flipped Not Flipped 120 125 Flipped Flipped Flipped Flipped 20 25 Not Flipped Flipped Flipped Flipped 70 75 Flipped Not Flipped Flipped Flipped 70 75 Flipped Flipped Not Flipped Flipped 70 75 Flipped Flipped Flipped Not Flipped 70 75 Not Flipped Not Flipped Not Flipped Flipped 120 125 Not Flipped Not Flipped Flipped Not Flipped 120 125 Not Flipped Flipped Not Flipped Not Flipped 120 125 Flipped Not Flipped Not Flipped Not Flipped 120 125 Not Flipped Not Flipped Flipped Flipped 120 125 Flipped Flipped Not Flipped Not Flipped 120 125 Not Flipped Flipped Not Flipped Flipped 70 75 Not Flipped Flipped Flipped Not Flipped 70 75 Flipped Not Flipped Not Flipped Flipped 70 75 Flipped Not Flipped Flipped Not Flipped 70 75

[0146]

[0147]

[0148] In an exemplary embodiment of the present disclosure, before determining the fixture type of the target welding fixture, the method further includes:

[0149] Obtain the initial model of the workpiece;

[0150] Obtain the click operation of the user on the initial model to annotate the initial model;

[0151] Generate the annotated model.

[0152] As can be seen from the above, when designing the pressing unit, it is necessary to obtain the workpiece template of the workpiece. Through the above method, this embodiment can quickly annotate the pre-designed initial model, and then read the annotated model, so that some parameters can be quickly obtained according to the annotated model, thereby generating the workpiece template.

[0153] Specifically, after generating the annotated model, the method further includes:

[0154] Read the annotated model;

[0155] Obtain the parameter item establishment operation of the user and establish the corresponding parameter item;

[0156] According to the name of the parameter item and the standard information in the annotated model, perform parameter grabbing on the annotated model to obtain the parameter corresponding to each parameter item;

[0157] Generate the workpiece template.

[0158] After obtaining the workpiece template through the above method, the workpiece template can be correspondingly obtained in response to the selection of the fixture type. However, some workpiece templates may not necessarily be suitable for all usage environments. Therefore, in this embodiment, a solution for quickly modifying parameters to implement the modification of the dimensions of the workpiece template is also provided to improve the design efficiency of designers.

[0159] Specifically, after obtaining the parameter corresponding to each parameter item, the method further includes:

[0160] In response to the user's modification of the parameter corresponding to the parameter item, adjust the dimensions of the model after the remarks according to the modified parameter.

[0161] According to one aspect of the present disclosure, a device for rapid design of a welding assembly fixture is provided, including:

[0163] A first acquisition module, configured to acquire a plurality of workpiece templates according to the fixture type; the workpieces corresponding to the plurality of workpiece templates are used to form the target welding fixture;
