Description

Technical Field

[0001] This utility model relates to the field of non-destructive testing technology, specifically a general-purpose magnetic particle inspection positioning tool for crossbeam steel pipe structures. Background Technology

[0002] In vehicle manufacturing and maintenance, to ensure the quality of welded parts or structural components, non-destructive testing of the frame is usually required. Magnetic particle testing, as a commonly used testing method, is widely used to detect surface or near-surface defects in steel structures. During magnetic particle testing, to ensure accuracy, the frame being tested needs to be stably supported and positioned to maintain consistent component posture.

[0003] In the magnetic particle inspection of existing vehicle frames, due to the significant differences in the structural dimensions of different vehicle models, existing positioning fixtures are usually customized for specific vehicle models and cannot flexibly adapt to the inspection needs of different frames. This results in frequent fixture changes, affecting the stability of the inspection results and operational efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a universal magnetic particle inspection positioning tool for crossbeam steel pipe structures.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A general-purpose magnetic particle inspection positioning fixture for crossbeam steel pipe frames includes:

[0007] Positioning reference base;

[0008] Two crossbeam steel pipe limiting seats are symmetrically arranged in the middle of the above-mentioned positioning reference seat along the length direction. They can slide along the length direction of the positioning reference seat. Each of the above-mentioned crossbeam steel pipe limiting seats is provided with two longitudinal adjustment blocks on the opposite side. The two longitudinal adjustment blocks can slide relative to the crossbeam steel pipe limiting seats in opposite directions.

[0009] Support seat one and support seat two are respectively set on both sides of the above-mentioned crossbeam steel pipe limiting seat along the width direction of the positioning reference seat, and the height of support seat one and support seat two is lower than the height of the longitudinal adjustment block. Support seat one is used to support the front of the frame, and support seat two is used to support the back of the frame.

[0010] Among them, the crossbeam steel pipe limiting seat and the longitudinal adjusting block slide together, and the side of the crossbeam steel pipe limiting seat away from the longitudinal adjusting block, the opposite side walls of the longitudinal adjusting block, and the top of support seat one and support seat two are all attached to the frame.

[0011] Preferably, the distance between the two aforementioned crossbeam steel pipe limiting seats is 500mm-700mm, and each of the aforementioned longitudinal adjusting blocks can slide relative to the crossbeam steel pipe limiting seat within a range of 30mm-50mm.

[0012] Preferably, the top of the positioning reference base has several sets of limiting guide rails, and the crossbeam steel pipe limiting base, support base one and support base two are all slidably set on the top of the positioning reference base via the limiting guide rails.

[0013] Preferably, the contact surfaces of the above-mentioned crossbeam steel pipe limiting seat, longitudinal adjusting block, support seat one and support seat two with the frame all have nylon anti-blocking blocks to reduce wear between them.

[0014] Preferably, the bottom of the aforementioned crossbeam steel pipe limiting seat has a drain outlet for the magnetic suspension fluid to flow through.

[0015] Preferably, each of the four corners of the aforementioned positioning reference base has a tooling positioning sleeve that penetrates the positioning reference base.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By sliding the crossbeam steel pipe limiting seat in conjunction with the longitudinal adjusting block, the horizontal and longitudinal dimensions of the frame can be flexibly adjusted, so that the same set of tooling can adapt to the positioning requirements of different vehicle frame structures, avoiding frequent tooling changes and effectively improving the efficiency of flaw detection operations and the inspection cycle.

[0018] 2. By setting support base one and support base two to support the front and back of the frame respectively, and combining the crossbeam steel pipe limiting seat and longitudinal adjustment block to achieve "multi-faceted fitting positioning", the spatial position and attitude of the frame can be stably limited, significantly improving the repeatability accuracy of component positioning during magnetic particle testing, and ensuring the consistency and comparability of test data.

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example

[0030] like Figures 1-3 As shown, a general-purpose crossbeam steel pipe frame magnetic particle inspection positioning fixture includes a positioning reference seat 1, two crossbeam steel pipe limiting seats 31, a support seat 1 21, and a support seat 22. The positioning reference seat 1 is used as the installation platform for the entire fixture, supporting and constraining the position of other functional structures to ensure the rigidity and stability of the overall structure. The positioning reference seat 1 is usually made of high-strength carbon steel plate welded structure to meet the equipment vibration and vehicle frame static load requirements during the magnetic particle inspection process.

[0031] In one embodiment, such as Figures 1-3 As shown, two crossbeam steel pipe limiting seats 31 are symmetrically arranged along the length of the middle of the positioning reference seat 1. They can slide along the length of the positioning reference seat 1 to adapt to the differences in lateral dimensions of different vehicle frame structures, thus realizing variable width positioning of the frame crossbeams. Each crossbeam steel pipe limiting seat 31 has two longitudinal adjustment blocks 32 on its opposite side, used to adjust the limiting dimensions of the frame in the longitudinal direction, i.e., the front-to-back direction of the vehicle. The two longitudinal adjustment blocks 32 can slide relative to the crossbeam steel pipe limiting seats 31 in opposite directions, having a certain adjustment range to adapt to differences in the longitudinal dimensions of the frame.

[0032] In one embodiment, such as Figure 1As shown, support seat 1 21 and support seat 22 are respectively set on both sides of the crossbeam steel pipe limiting seat 31 along the width direction of the positioning reference seat 1. The height of support seat 1 21 and support seat 22 is lower than the height of the longitudinal adjusting block 32. The height of both is designed to be lower than the longitudinal adjusting block 32 so that the frame is stably clamped between the multi-point limiting structures during the flaw detection process, thereby improving the overall positioning stability. Support seat 1 21 is used to support the front of the frame, and support seat 22 is used to support the back of the frame. The coordinated sliding adjustment between the crossbeam steel pipe limiting seat 31 and the longitudinal adjusting block 32 allows different edges of the frame to simultaneously fit against the side of the crossbeam steel pipe limiting seat 31 away from the longitudinal adjusting block 32, the two sides of the two longitudinal adjusting blocks 32 opposite to each other, and the top of support seat 1 21 and support seat 22, forming a "three-sided limiting and two-sided support" frame clamping effect, thereby improving positioning accuracy and anti-slip performance, and meeting the needs of multi-vehicle structure adaptation.

[0033] In one embodiment, such as Figures 1-3 As shown, the distance between the two crossbeam steel pipe limiting seats 31 ranges from 500mm to 700mm, and each longitudinal adjusting block 32 can slide relative to the crossbeam steel pipe limiting seat 31 within a range of 30mm to 50mm. This distance range covers the lateral and longitudinal positioning requirements of multiple existing vehicle project frames, giving the tooling good "versatility" and "adaptability." This avoids the repetitive manufacturing investment of customizing positioning devices for different vehicle models, improving the equipment's economy and on-site adaptability. Furthermore, it avoids the decrease in structural stability caused by excessive adjustment stroke.

[0034] In one embodiment, such as Figure 1 As shown, the top of the positioning reference base 1 has several sets of limiting guide rails 12. The crossbeam steel pipe limiting base 31, support base one 21 and support base two 22 are all slidably set on the top of the positioning reference base 1 via the limiting guide rails 12. The setting of the limiting guide rails 12 helps to ensure that the position of each sliding component is controlled and the posture is stable during the adjustment process, avoids measurement errors caused by lateral or longitudinal shaking, and improves positioning repeatability and structural fit accuracy.

[0035] In one embodiment, such as Figure 1 As shown, the contact surfaces of the crossbeam steel pipe limiting seat 31, longitudinal adjustment block 32, support seat one 21 and support seat two 22 with the frame all have nylon anti-blocking blocks 4 to reduce wear between them. The nylon anti-blocking blocks 4 have good wear resistance and flexible buffering performance, which can reduce hard contact between the tooling and the frame, reduce the risk of scratches on the frame surface, and are particularly suitable for the protection of the finished frame before flaw detection. At the same time, they extend the service life of the tooling, reflecting the unity of structural optimization and safety of use.

[0036] In one embodiment, such as Figure 1As shown, the bottom of the crossbeam steel pipe limiting seat 31 has a drain port for the magnetic suspension fluid to flow through. This structural design ensures that the magnetic particle testing fluid will not accumulate at the bottom of the structure during actual flaw detection operations, avoiding liquid stagnation that could affect positioning accuracy and subsequent operations, keeping the device surface clean, and facilitating the long-term stable operation of the tooling. Each of the four corners of the positioning reference seat 1 has a tooling positioning sleeve 11 that penetrates the positioning reference seat 1. This structure facilitates the quick and accurate installation of the entire tooling on a standardized platform or fixture table, improving the repeatability of the entire tooling installation, shortening the clamping time each time, and also facilitating rapid equipment switching and standardized deployment. It is suitable for multi-station layouts and rapid changeover scenarios in workshops.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
