[0048] Example

[0049] Existing inspection tooling solutions generally include individual product inspection tools and assembly inspection tools designed and developed for production site services. Individual product inspection tools are for the management needs of second-tier suppliers (such as mold factories), while assembly inspection tools are for the final quality requirements of customers (such as various OEMs). Component integrators generally use individual product inspection tools to determine whether the stamped parts from the mold factory meet the design requirements, and use the inspection results of assembly inspection tools to make adjustments to ensure that the quality of the assembly meets the customer's drawing requirements.

[0050] During the design process, the inventors discovered that the integration from individual components to the final assembly generally involves multiple production processes. Inevitably, there will be production variables and cumulative tolerances between processes. Only when the processes are stable and the sum of process variables is zero can the assembly accuracy meet the accuracy and stability requirements. The measurement and matching analysis requirements of these process components are not provided by the existing individual component inspection tools, assembly inspection tools, or even fixtures. Therefore, without inspection methods for each process component, the accuracy analysis of the assembly becomes unclear, resulting in time-consuming and iterative debugging, which affects the efficiency of the assembly. If inspection tools are developed for each process and all individual component inspection tools are centralized at the site of the first-tier supplier for confirmation, it will increase the investment in tooling and transportation costs, and also occupy the mold training time, affecting the efficiency of improving the maturity of assembly accuracy.

[0051] In view of this, such as Figures 1-11 As shown, in a first aspect, embodiments of this application provide an inspection fixture device, including: a product structure 10 and an inspection fixture structure 20. The product structure 10 includes, but is not limited to, a front-end module assembly applied to a vehicle body. The product structure 10 can be placed on the inspection fixture structure 20, and clamped and positioned by the inspection fixture structure 20. It can perform not only single-piece inspection but also inspection after connection. Of course, it is also possible to place several single pieces of the product structure 10 on the inspection fixture structure 20 and connect them on the inspection fixture structure 20, etc., to provide a feasible, reliable, and low-cost inspection fixture design method and solution, which can at least solve one of the technical problems existing in the prior art.

[0052] Specifically, product structure 10 includes a first product component 101, a second product component 102, and a third product component 103. The first product component 101 is connected to the second product component 102 to form a fourth product component 104, and the fourth product component 104 is connected to the third product component 103. Inspection fixture structure 20 includes a first positioning reference component 21, a second positioning reference component 22, a third positioning reference component 23, and a detection component 24. The first positioning reference component 21, the second positioning reference component 22, the third positioning reference component 23, and the detection component 24 are spaced apart. The first positioning reference component 21 is used for clamping and positioning the first product component 101 and / or the fourth product component 104. The second positioning reference component 22 is used for clamping and positioning the second product component 102 and / or the fourth product component 104. The third positioning reference component 23 is used for the third product component 103. The detection component 24 is used for detecting the product structure 10.

[0053] For example, the first product component 101, the second product component 102, and the third product component 103 are all single pieces. The order in which they are connected is as follows: first, the first product component 101 and the second product component 102 are welded together to form the fourth product component 104. The fourth product component 104 is then welded together with the third product component 103 to finally form the product structure 10. The inspection fixture structure 20 serves as an inspection tool, which can not only be used for clamping and positioning of a single piece, but also for inspection after several single pieces are welded together, completing the measurement from single piece to assembly (i.e., the structure formed after at least several single pieces are welded together).

[0054] It should be noted that, in order to improve efficiency, the first positioning reference component 21, the second positioning reference component 22 and the third positioning component are all designed with quick-replacement structure and can be flexibly combined and used. Furthermore, the first positioning reference component 21, the second positioning reference component 22 and the third positioning reference component 23 can be manually adjusted to adapt or disengage the inspection fixture structure 20 from the product structure 10. This manual method can be controlled by using a handle and a connecting rod.

[0055] In the above implementation process, the first positioning reference component 21, the second positioning reference component 22, the third positioning reference component 23, and the detection component 24 are distributed at intervals. The first positioning reference component 21 can clamp and position the first product component 101 independently, the second positioning reference component 22 can clamp and position the second product component 102 independently, and the third positioning reference component 23 can clamp and position the third product component 103 independently. This enables the analysis and evaluation of individual components before connection. At the same time, the first positioning reference component 21, the second positioning reference component 22, the third positioning reference component 23, and the detection component 24 can be used in combination to confirm the direction and amount of connection changes, lock in the influence of individual components and the quantitative analysis and improvement direction of connection influence, further improve stability, and thus improve product quality and detection efficiency.

[0056] like Figures 4-5 As shown, the first product component 101 includes a first bracket 1013, a first second bracket 1014, a first third bracket 1015, and a first fourth bracket 1016. The first first bracket 1013 is connected to the first second bracket 1014 to form a first sub-product 1011. The first third bracket 1015 is connected to the first fourth bracket 1016 to form a second sub-product 1012. The first sub-product 1011 and the second sub-product 1012 are located at both ends of the second product component 102.

[0057] For example, the first sub-product 1011 and the second sub-product 1012 are configured in the same way, and the first sub-product 1011 is located on the right side of the second product component 102, and the second sub-product 1012 is located on the left side of the second product component 102.

[0058] In the above-mentioned process, the first sub-product 1011 or the second sub-product 1012 can be clamped and positioned by the first positioning reference component 21 to perform analysis and evaluation before single-piece connection, confirm the matching status of the first sub-product 1011 or the second sub-product 1012, and provide information support for the analysis of connection process variables. Alternatively, after the first sub-product 1011 or the second sub-product 1012 is connected, it can be clamped and positioned by the inspection fixture structure 20 to confirm the direction and amount of connection change, so as to lock the direction of improvement, quantitative analysis of single-piece influence and connection influence, improve stability, improve product quality and inspection efficiency, and reduce cost input.

[0059] like Figures 6-7 As shown, the second product component 102 includes a second body 1021, a second bracket 1022, a second third bracket 1023, a second fourth bracket 1024, a second fifth bracket 1025, a second sixth bracket 1026, a second seventh bracket 1027, a second eighth bracket 1028, and a second ninth bracket 1029. The second second bracket 1022, the second third bracket 1023, the second fourth bracket 1024, the second fifth bracket 1025, the second sixth bracket 1026, the second seventh bracket 1027, the second eighth bracket 1028, and the second ninth bracket 1029 are respectively connected to the second body 1021.

[0060] For example, the second body 1021 is connected to the first sub-product 1011 and the second sub-product 1012 respectively. The second third bracket 1023 and the second sixth bracket 1026 are located on the right side of the second body 1021. The second fourth bracket 1024, the second fifth bracket 1025 and the second ninth bracket 1029 are located on the left side of the second body 1021. The second second bracket 1022 is located between the second seventh bracket 1027 and the second eighth bracket 1028, and the second second bracket 1022, the second seventh bracket 1027 and the second eighth bracket 1028 are located between the second third bracket 1023 and the second fourth bracket 1024.

[0061] In the above process, after several brackets are connected to the main body in sequence, they can be clamped and positioned by the second positioning reference component 22 to perform analytical evaluation before the connection of individual parts. After the second product component 102 is connected, it can be clamped and positioned by the inspection fixture structure 20 to confirm the direction and amount of connection change, so as to lock the direction of improvement, quantitatively analyze the impact of individual parts and connection, improve stability, improve product quality and testing efficiency, and reduce cost input.

[0062] like Figures 8-9 As shown, the third product component 103 includes a third first body 1031, a third second bracket 1032, and a third third bracket 1033, with the third second bracket 1032 and the third third bracket 1033 respectively connected to the third first body 1031. For example, the third second bracket 1032 and the third third bracket can be configured as a symmetrical structure, with the third second bracket 1032 located on the left side of the third first body 1031 and the third third bracket 1033 located on the right side of the third first body 1031.

[0063] In the above-mentioned process, after the brackets are connected to the main body, they can be clamped and positioned by the third positioning reference component 23 to perform analysis and evaluation before the connection of individual parts. After the third product component 103 is connected, it can be clamped and positioned by the inspection fixture structure 20 to confirm the direction and amount of connection change, so as to lock the direction of improvement, quantitative analysis of the impact of individual parts and the impact of connection, improve stability, improve product quality and testing efficiency, and reduce cost input.

[0064] like Figure 5 As shown, the first positioning reference component 21 is configured in two sets. One set of the first positioning reference component 21 is configured to clamp and position the first sub-product 1011, and the other set of the first positioning reference component 21 is configured to clamp and position the second sub-product 1012. The first positioning reference component 21 includes a first positioning reference pin 210, a first second positioning reference pin 211, a first first positioning reference block 212, a first second positioning reference block 213, and a first third positioning reference block 214 distributed at different positions of the first product component 101.

[0065] Taking the first sub-product 1011 as an example, the first positioning reference pin 210, the first second positioning reference pin 211, the first positioning reference block 212, the first second positioning reference block 213, and the first third positioning reference block 214 are all connected to the first bracket 1013. Of course, in order to ensure the clamping and positioning of the first second bracket 1014, the first positioning reference assembly 21 also includes the first third positioning reference pin 215, the first fourth positioning reference pin 216, the first fourth positioning reference block 217, and the first fifth positioning reference block 218, so as to confirm the matching gap between the first bracket 1013 and the first second bracket 1014 and provide information support for the analysis of welding process variables.

[0066] In the above-mentioned process, the first positioning reference component 21 clamps and positions the first sub-product 1011 or the second sub-product 1012, which can realize the analysis and evaluation of the individual parts before connection, and can also determine the direction and amount of change after connection by the fixture structure 20 after connection, lock the influence of the individual parts and the influence of connection, quantify and analyze and improve the direction, improve stability, reduce tooling investment and transportation costs, reduce the time occupied for training, improve product accuracy and increase efficiency.

[0079] This application includes five production processes, namely:

[0080] First production process: The first production process mainly involves the production of the first product component 101 (the same applies to the first product component 101 on the left). Before production, the first product component 101 is matched based on the structure of a local area of ​​the fixture structure 20. Pre-welding analysis and evaluation are performed on each individual component. Specifically, the first sub-product 1011 is clamped and positioned using a reference system composed of the first positioning reference pin 210, the first second positioning reference pin 211, the first first positioning reference block 212, the first second positioning reference block 213, and the first third positioning reference block 214. Then, the second sub-product 1012 is clamped and positioned using a reference system composed of the first third positioning reference pin 215, the first fourth positioning reference pin 216, the first fourth positioning reference block 217, and the first fifth positioning reference block 218, thereby achieving… The matching gap between the first sub-product 1011 and the second sub-product 1012 is confirmed to provide information support for the analysis of welding process variables. After the welding of the first product component 101 is completed, the first product component 101 is clamped and positioned by the reference system of the first positioning reference pin 210, the first second positioning reference pin 211, the first first positioning reference block 212, the first second positioning reference block 213, and the first third positioning reference block 214. The direction and amount of welding change are confirmed by the reference offset confirmation of the first third positioning reference pin 215, the first fourth positioning reference pin 216, the first fourth positioning reference block 217, and the first fifth positioning reference block 218. Thus, the individual influence and welding influence of the first product component 101 are quantitatively analyzed and the improvement direction is locked, and the stability can be further monitored and improved.

[0081] The second production process mainly involves the production of the second product component 102, specifically including the welding of the second body 1021 and eight brackets (two to nine in total). Before the production of the second product component 102, the structure of a local area of ​​the fixture structure 20 is matched, and the individual parts are analyzed and evaluated before welding. After the welding of the second product component 102 is completed, the second product component 102 is clamped and positioned by a reference system composed of the third positioning reference pin 220, the third and second positioning reference pins 221, the sixth positioning reference block 222, the sixth and second positioning reference block 223, the sixth and third positioning reference block 224, and the sixth and fourth positioning reference block 225. The hole and surface misalignment of the eight brackets (two to nine in total) are confirmed by detection blocks such as the first detection block 240, the second detection block 241, and the third detection block 242, and the direction and amount of welding changes are confirmed. This allows for the quantitative analysis and improvement of the individual impact and welding impact of the second product component 102, and further monitoring and improvement of stability.

[0082] The third production process mainly involves the production of the third product component 103, specifically including the welding of the third body 1031 and two brackets (the third second and third third brackets). Before production, the third product component 103 is matched based on the local area structure of the inspection fixture, and the individual parts are analyzed and evaluated before welding. After the welding of the third product component 103 is completed, the third product component 103 is clamped and positioned by a reference system composed of the fourth positioning reference pin 230, the fourth second positioning reference pin 231, the fifth first positioning reference block 232, the fifth second positioning reference block 233, the fifth third positioning reference block 234, and the fifth fourth positioning reference block 235. The misalignment of the matching surfaces of the third second bracket 1032 and the third third bracket 1033 is confirmed by four profiling detection blocks composed of the fourth detection block 243, the fifth detection block 244, the sixth detection block 245, and the seventh detection block 246, which confirm the direction and amount of welding changes. This allows for the quantitative analysis and improvement of the individual impact and welding impact of the third product component 103, and further monitoring and improvement of stability.

[0083] The fourth production process mainly involves the combination and welding of the first sub-product 1011, the second product assembly 102, to form the fourth product assembly 104. Before production, the fourth product assembly 104 is evaluated and matched based on the structure of a local area of ​​the fixture structure 20 and three sets of positioning references. Specifically, the first sub-product 1011 and the second sub-product 1012 are clamped and positioned by a reference system consisting of two sets of first positioning reference pins 210, first and second positioning reference pins 211, first positioning reference blocks 212, first and second positioning reference blocks 213, and first and third positioning reference blocks 214, respectively. The second product assembly 102 is clamped and positioned by a reference system consisting of third positioning reference pins 220, third and second positioning reference pins 221, sixth positioning reference blocks 222, sixth and second positioning reference blocks 223, sixth and third positioning reference blocks 224, and sixth and fourth positioning reference blocks 225. The clamping and matching on the same fixture structure 20 achieves the matching of the second product assembly 104. The matching gap between product component 102 and the first sub-product 1011 or the second sub-product 1012 is confirmed to provide information support for the analysis of welding process variables. After the fourth product component 104 is welded, the fourth product component 104 is clamped and positioned by a reference system composed of the third positioning reference pin 220, the third and second positioning reference pins 221, the first positioning reference block 212, the first and second positioning reference block 213, and the first and third positioning reference block 214. The corresponding reference offset and target bracket accuracy are measured by the first positioning reference pin 210, the first and second positioning reference pins 211, the sixth positioning reference block 222, the sixth and second positioning reference block 223, the sixth and third positioning reference block 224, the sixth and fourth positioning reference block 225, and the example detection block. The welding change direction and amount are compared with the previous process data to confirm the accuracy influence and welding influence of the first product component 101 and the second product component 102, and to lock the improvement direction. The stability can be further monitored and improved.

[0084] Fifth production process: The fifth production process mainly involves the combination and welding of the fourth product component 104 and the third product component 103 to form the product structure 10 (hereinafter referred to as the product). Before the product is produced, the matching analysis and evaluation before welding is achieved based on the structure of a local area of ​​the fixture structure 20 and two sets of positioning references. Specifically, the fourth product component 104 is clamped and positioned by a reference system composed of the third first positioning reference pin 220, the third second positioning reference pin 221, the first first positioning reference block 212, the first second positioning reference block 213, and the first third positioning reference block 214. The fourth product component 104 is clamped and positioned by a reference system composed of the fourth first positioning reference pin 230, the fourth second positioning reference pin 231, the fifth first positioning reference block 232, the fifth second positioning reference block 233, the fifth third positioning reference block 234, and the fifth fourth positioning reference block 235. The reference system clamps and positions the third product component 103. The matching gap between the third product component 103 and the fourth product component 104 is confirmed through the clamping and matching on the same set of inspection fixture structure 20, providing information support for the analysis of welding process variables. After the product is welded, the product is clamped and positioned by the reference system composed of the third first positioning reference pin 220, the third second positioning reference pin 221, the first second positioning reference block 213, and the first third positioning reference block 214. The positional information of all managed bracket surfaces and holes is measured and confirmed by example detection blocks to confirm whether they meet the drawing requirements. If they do not meet the requirements, the offset of other references under the corresponding third and fourth reference systems is further measured to complete the analysis of welding change direction and amount by comparing with the previous process data.
