Description

Technical Field

[0001] This utility model relates to the field of bracket inspection technology, specifically a comprehensive inspection tool for quickly detecting bracket dimensions. Background Technology

[0002] With the rapid development of the automotive industry and increasingly fierce competition among car manufacturers, coupled with the country's strengthened control over the environment and energy, lightweighting of automobiles has become an inevitable trend. Energy-saving and environmentally friendly vehicles are the inevitable choice for the sustainable and healthy development of my country's automotive industry in the future. The lightweight design of the brake system component bracket reduces the strength of the material itself. During the casting process, the proportion of workpiece collision deformation increases due to sand removal during the rolling process and shot blasting process. In order to effectively control the bracket size, dimensional inspection is required. Since multiple dimensions can deform, each process needs to be inspected, resulting in many inspection steps, low efficiency, and low accuracy of inspection results. This leads to high inspection costs and frequent occurrences of defective products.

[0003] To improve testing efficiency while ensuring testing accuracy, there is an urgent need for a comprehensive inspection tool that can quickly measure the size of brackets, avoiding the problem of low testing accuracy caused by multiple testing processes. Utility Model Content

[0004] The problem to be solved is to provide a comprehensive inspection tool for rapid detection of bracket dimensions, avoiding the problem of low detection accuracy caused by multi-process inspection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a comprehensive inspection tool for rapidly detecting the dimensions of a support, comprising a Y-base providing a detection reference plane; symmetrically arranged on both sides of the Y-base are left and right outer contour dimension inspection blocks for detecting the total length of the outer section of the support casting; between the left and right outer contour dimension inspection blocks are left and right inner contour dimension inspection blocks for detecting the width of the inner section of the support casting; between the left and right inner contour dimension inspection blocks are coarse beam dimension inspection blocks; the Y-base also provides fine beam outer dimension inspection blocks and fine beam inner dimension inspection blocks, with a fine beam groove between the fine beam outer dimension inspection blocks and the fine beam inner dimension inspection blocks; and at both ends of the fine beam outer dimension inspection blocks are left and right Z-base reference blocks vertically fixed to the Y-base.

[0006] Preferably, both the left outer contour dimension inspection block and the right outer contour dimension inspection block are fixedly connected to the Y reference base.

[0007] Preferably, the coarse beam dimension inspection block is provided with a coarse beam step, which engages with the coarse beam of the support casting.

[0008] Preferably, the width of the groove in the thin beam is the same as the width of the thin beam in the support casting.

[0009] Preferably, the Y-reference base is also provided with a left support slot and a right support slot.

[0010] Preferably, a left retaining ring groove outer contour inspection block and a right retaining ring groove outer contour inspection block are provided corresponding to the left Z reference block and the right Z reference block. The left retaining ring groove outer contour inspection block is engaged with the bottom of the left inner contour dimension inspection block, and the right retaining ring groove outer contour inspection block is engaged with the bottom of the right inner contour dimension inspection block.

[0011] Compared with existing technologies, this utility model provides a comprehensive inspection tool for rapid detection of bracket dimensions, which has the following beneficial effects: This utility model sets up a Y-reference base, on which multiple sets of blocks are set, namely, left and right outer contour dimension inspection blocks, left and right inner contour dimension inspection blocks, coarse beam dimension inspection blocks and fine beam outer dimension inspection blocks, left and right Z-reference blocks, and left and right snap ring groove outer contour inspection blocks. Multiple sets of inspection blocks enable simultaneous one-time inspection of multiple dimensions, reducing the single-piece inspection time from 12 seconds to 5 seconds, and increasing the inspection volume per shift from 800 pieces to 1300 pieces, improving efficiency by 62.5%. Each set of blocks is fixed on the Y-reference base, with a Y-reference flatness error ≤0.02mm, an inner width D inspection accuracy of ±0.05mm, and a Z-direction deformation detection resolution of 0.01mm. Through full-size coverage inspection, the deformation defect rate is reduced from 0.35% to 0%, eliminating potential quality problems. Attached Figure Description

[0020] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model:

[0021] like Figure 1 The diagram shown is an isometric view of the support casting 10. The support casting 10 includes a thick beam 101, a thin beam 102, a left circlip groove outer contour 103, and a right circlip groove outer contour 104. The dimensions to be inspected include... Figure 1 The inner width D shown Figure 6 The outer width L shown and Figure 7 The following parameters are shown: the width a of the thin beam 102, the minimum distance b between the thin beam 102 and the Z-reference plane, the maximum distance c between the thin beam 102 and the Z-reference plane, the distance e between the bottom surface of the bracket casting 10 and the bottom of the thin beam groove 72, the maximum distance P of the thick beam 101 from the Z-reference plane, and the maximum distance N of the outer contours 103 and 104 of the left and right circlip grooves from the Z-reference plane. To achieve a single measurement of whether the above multiple dimensional parameters of the bracket casting 10 meet the requirements, this utility model provides a comprehensive inspection tool for quickly detecting the dimensions of the bracket, such as... Figures 2-7 As shown, it includes a Y-reference base 1 that provides a reference plane for the inspection. The Y-reference base 1 serves as the reference plane for the inspection, ensuring that all dimensional measurements are based on the same coordinate system, establishing a system as shown below. Figure 4The coordinate system shown; the Y-reference base 1 is also provided with a left support groove 11 and a right support groove 12, which are used to accommodate the arc-shaped components on both sides of the bracket casting 10 and to detect the maximum outer contour dimension of the arc-shaped parts on both sides. Symmetrically arranged on both sides of the Y-reference base 1 are a left outer contour dimension inspection block 2 and a right outer contour dimension inspection block 3 for detecting the total length of the outer section of the bracket casting 10. Both the left outer contour dimension inspection block 2 and the right outer contour dimension inspection block 3 are fixedly connected to the Y-reference base 1. The left outer contour dimension inspection block 2 and the right outer contour dimension inspection block 3 detect that the maximum total length of the outer section of the bracket casting 10 does not exceed L. Between the left outer contour dimension inspection block 2 and the right outer contour dimension inspection block 3 are a left inner contour dimension inspection block 42 and a right inner contour dimension inspection block 52 for detecting the width of the inner section of the bracket casting 10. A fixed distance is maintained between the left inner contour dimension inspection block 42 and the right inner contour dimension inspection block 52 to detect the bracket. The minimum width of the inner section of casting 10 is not less than D; a coarse beam dimension inspection block 6 is provided between the left inner contour dimension inspection block 42 and the right inner contour dimension inspection block 52. The coarse beam dimension inspection block 6 has a coarse beam step 61, which engages with the coarse beam 101 of the support casting 10; the height and width of the coarse beam step 61 match the design dimensions of the coarse beam 101; the Y-reference base 1 is also provided with a fine beam outer dimension inspection block 7 and a fine beam inner dimension inspection block 71. A fine beam groove 72 is provided between the fine beam outer dimension inspection block 7 and the fine beam inner dimension inspection block 71. The groove width of the fine beam groove 72 is consistent with the width of the fine beam 102 of the support casting 10. The fine beam groove 72 engages the fine beam 102 to check whether the width dimension of the fine beam 102 exceeds the tolerance. Figure 7 Whether the width 'a' of the thin beam 102 exceeds the tolerance; the thin beam outer dimension inspection block 7 is equipped with a left Z reference block 8 and a right Z reference block 9 at both ends of the vertical Y reference base 1. The left Z reference block 8 and the right Z reference block 9 cooperate with the thin beam outer dimension inspection block 7 to check the maximum distance 'c'. The left Z reference block 8 and the right Z reference block 9 serve as the Z-direction reference plane. They cooperate with the coarse beam dimension inspection block 6 to detect the maximum distance 'P' of the coarse beam 101 from the Z-direction reference plane. The left Z reference block 8 cooperates with the left snap ring groove outer contour inspection block 41 to detect the maximum distance 'N' of the left snap ring groove outer contour 103 from the Z-direction reference plane. The right Z reference block 9 cooperates with the right snap ring groove outer contour inspection block 51 to detect the maximum distance 'N' of the right snap ring groove outer contour 104 from the Z-direction reference plane. The left Z reference block 8 and the right Z reference block 9 cooperate with the thin beam inner dimension inspection block 71 to detect the minimum distance 'b'. The Y reference base 1 and the bottom of the thin beam groove 72 are used to detect the minimum distance 'e'.

[0022] In use, the bracket casting 10 is placed on the Y-reference base 1, the thick beam 101 is engaged with the thick beam step 61, and the thin beam 102 is embedded in the thin beam groove 72. If the bracket casting 10 can be completely lowered and engaged in the tooling, then... Figure 6 , Figure 7All dimensions L, D, N, P, a, b, c, and e conform to product requirements; if they cannot be fitted into the fixture, they do not meet the requirements. The inspection process is quick and convenient: simply insert the fixture, check for fit, and remove it. Production inspection efficiency has been significantly improved by 62.5% (800 pieces / shift → 1300 pieces / shift), effectively controlling the quality of 10 parts of the bracket casting, reducing the defective outflow rate from 0.35% to 0%. This not only ensures inspection efficiency but also avoids errors from manual inspection, ensuring the quality of shipped products.

[0023] This invention provides a comprehensive inspection tool for rapid inspection of bracket dimensions. By integrating a Y-reference base, inner and outer contour blocks, coarse / fine beam inspection blocks, a Z-reference block, and left and right retaining ring groove outer contour inspection blocks, it enables simultaneous multi-dimensional inspection of lightweight automotive brackets. The Y-reference base serves as a planar reference, and combined with fixed outer and inner blocks, accurately measures the total length L of the outer section and the width D of the inner section. The coarse beam step and fine beam groove adapt to the bracket structure, quickly identifying dimensional deviations. In practical applications, this tool improves inspection efficiency by 62.5%, reduces the defect rate to near zero, and significantly lowers production costs.
