[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figures 1 to 4As shown, the utility model is a kind of inspection tool for air intake grille 1, the air intake grille 1 has a curved surface 10 and a flat surface 11 with a height difference, and the two ends of the curved surface 10 and the flat surface 11 are connected to each other, wherein the inspection tool comprises: a detection platform 2; a profiling frame 3, which is arranged on the detection platform 2, and the side wall of the profiling frame 3 is formed with an arc-shaped positioning surface 30, so that the air intake grille 1 is placed on the detection platform 2 in a vertical posture, and the curved surface 10 is parallel to and close to the arc-shaped positioning surface 30; a plurality of positioning blocks 4, which are arranged on the arc-shaped positioning surface 30, and positioning holes 120 are formed on the curved surface 10 and the flat surface 11, and the positioning blocks 4 are movably inserted in the positioning holes 120 to limit the displacement of the air intake grille 1 relative to the profiling frame 3 in the height direction; a first positioning base 50 and a second positioning base 51 which are non-equidistantly arranged on the arc-shaped positioning surface 30, and the first positioning base 50 and the second positioning base 51 correspond to the curved surface 10 and the flat surface 11 respectively, and in the first positioning The base 50 and the second positioning base 51 are both provided with locking holes 520, and the flat surface portion 11 and the curved surface portion 10 are both formed with a plurality of detection holes 121; when the end faces of the first positioning base 50 and the second positioning base 51 are respectively movably pressed against the curved surface portion 10 and the flat surface portion 11, the locking holes 520 are aligned with the detection holes 121 and are interconnected; the detection mechanism 6 is movably arranged at the top end of the profiling frame 3, and the detection mechanism 6 is provided with a flip block 60 and a positioning detection block 61, and the positioning The detection block 61 can be movably inserted into the flat portion 11 when it is flipped and movably pressed against the outer wall of the flat portion 11 as the flip block 60 is flipped, so as to detect the placement position of the air intake grille 1 relative to the profiling frame 3; a plurality of pressing blocks 333 and detection columns 7, a plurality of pressing blocks 333 are movably arranged on both sides of the arc-shaped positioning surface 30, so as to be movably pressed against the air intake grille 1; the detection column 7 is used to movably penetrate the detection hole 121 and be connected to the locking hole 520 to detect the processing quality of the detection hole 121.

[0035] like Figure 1As shown, the air intake grille 1 in this embodiment consists of a curved surface portion 10 and a flat surface portion 11, and the heights and positions of the two are different. The inspection tooling needs to synchronously complete the corresponding inspection of the structure. First, the air intake grille 1 to be inspected is placed on the inspection table 2 in a vertical posture, wherein the curved surface portion 10 is parallel to and close to the arc-shaped positioning surface 30 on the profiling frame 3, so as to ensure that the air intake grille 1 can be accurately aligned with the inspection tooling. During this process, the positioning block 4 can be inserted into the positioning hole 120 of the air intake grille 1, thereby limiting its position change in the height direction. At the same time, the end faces of the first positioning base 50 and the second positioning base 51, which are unequally spaced, respectively abut against the curved surface portion 10 and the flat surface portion 11, which, on the one hand, serve as a reference positioning for the air intake grille 1, and on the other hand, cooperate with the positioning block 4 to further provide a fixed support for the air intake grille 1, thereby ensuring the stability of the air intake grille 1 during the inspection process. By flipping the flip block 60 in the detection mechanism 6, the positioning detection block 61 is pressed against the outer wall of the flat portion 11 of the air intake grille 1 and inserted into the corresponding position in the flat portion 11, thereby checking whether the placement position of the air intake grille 1 relative to the profiling frame 3 is correct. For the subsequent detection column 7, as the pressing block 333 presses and fixes the air intake grille 1, multiple detection columns 7 will pass through the detection holes 121 at different positions and connect with the locking holes 520, so that it can be detected whether the processing quality of the detection holes 121 meets the standard. It can be seen that the inspection tool only needs to clamp the air intake grille 1 once to simultaneously complete the required inspection functions of the curved surface portion 10 and the flat surface portion 11. The overall structure is simple, the operation is convenient and fast, and while saving manpower loss, it also avoids the accumulation of reference errors and even product damage caused by frequent assembly and disassembly of the air intake grille 1, thereby greatly ensuring the inspection quality and improving the overall inspection efficiency.

[0036] A fixed guide sleeve 521 is provided in the locking hole 520 , and a locking ring 70 is connected to the detection column 7 . The detection column 7 passes through the detection hole 121 and is inserted into the fixed guide sleeve 521 , and is movably pressed against the flat surface portion 11 or the curved surface portion 10 through the locking ring 70 .

[0037] like Figures 2 to 3 As shown, during the placement of the air intake grille 1, the first positioning base 50 and the second positioning base 51 with the fixed guide sleeve 521 are pressed against the curved surface 10 and the flat surface 11 of the air intake grille 1. At this time, the fixed guide sleeve 521 should be exactly below the detection hole 121. After the overall position of the air intake grille 1 is fixed, the detection column 7 passes through the detection hole 121 and is inserted into the fixed guide sleeve 521. At this time, the locking ring 70 will be pressed tightly against the curved surface 10 or the flat surface 11 of the air intake grille 1 to prevent the detection column 7 from being separated from the detection hole 121 due to gravity or other external forces.

[0038] Preferably, the profiling platform in this embodiment includes a first detection part 31 and a second detection part 32 connected to each other, wherein the first positioning base 50 is installed on the first detection part 31, and the second positioning base 51 is installed on the second detection part 32. The structure adopts a split design, which is conducive to the installation and disassembly of the first positioning base 50 and the second positioning base 51 on the one hand, and on the other hand, it is convenient for adjusting the position of the positioning base to ensure that the locking hole 520 is aligned with the detection hole 121 on the air intake grille 1, thereby ensuring the smoothness and accuracy of the subsequent detection column 7 detection.

[0039] A mounting base 33 is provided on the profiling frame 3, and a rotating block 330 and a rotating wrench 331 are hingedly connected to the mounting base 33. The pressing block 333 is connected to the end of the rotating block 330. A connecting plate 332 is hinged between the rotating wrench 331 and the rotating block 330, so that when the rotating wrench 331 rotates, the pressing block 333 is driven to move closer to or away from the air intake grille 1 through the rotating block 330.

[0040] like Figure 2 As shown, after the air intake grille 1 is positioned, the worker can operate the rotating wrench 331 to rotate relative to the mounting seat 33. During this process, the rotating block 330 is driven to rotate by the action of the connecting plate 332, and then the pressing block 333 is driven to gradually approach the air intake grille 1. When the pressing block 333 is completely pressed against the air intake grille 1, the operation of rotating the wrench 331 can be stopped. The overall structure is relatively simple, which brings convenience to the tightening and loosening operations of the air intake grille 1, and improves the work efficiency of the inspection tool when installing and removing the air intake grille 1.

[0041] Preferably, if Figure 2 As shown, in this embodiment, a clearance hole 333a is formed at the end of the clamping block 333. The clearance hole 333a is U-shaped as a whole. While ensuring that the air intake grille 1 is clamped and fixed, it can also ensure that the detection column 7 smoothly passes through the clearance hole 333a and penetrates the detection hole 121 to achieve the corresponding detection operation. The two structures do not interfere with each other, ensuring stability during detection.

[0042] The detection mechanism 6 also includes: a fixed seat 62, which is mounted on the top wall of the profiling frame 3, and the end of the flip block 60 is hinged in the fixed seat 62; a reference block 63, which is connected to the end of the flip block 60 away from its rotation center, and a reference platform 64 arranged parallel to the plane portion 11 is installed on both sides of the reference block 63, and the positioning detection block 61 is vertically mounted on the reference platform 64.

[0043] like Figure 2 and Figure 4As shown, before the air intake grille 1 is installed, the flip block 60 is positioned above the contour frame 3, facilitating horizontal placement of the air intake grille 1 in a vertical position on the contour frame 3. Once the air intake grille 1 is positioned, the flip block 60 is flipped within the fixing seat 62, causing the reference block 63 to rotate along the rotation center of the flip block 60 until the reference block 63 rests against the flat surface 11 of the air intake grille 1. At this point, the positioning detection block 61 is vertically inserted into the flat surface 11 to detect the correct placement of the air intake grille 1 relative to the contour frame 3. This ensures the accuracy of the subsequent inspection of the air intake grille 1 by the inspection column 7.

[0044] Preferably, in this embodiment, the end of the flip block 60 away from the reference block 63 can be hinged in the fixed seat 62 through a connecting shaft (not shown in the figure), so that the flip block 60 drives the reference block 63 to rotate relative to the fixed seat 62 along the axis of the connecting shaft.

[0045] A guide groove 620 is provided in the fixing seat 62, and a locking hole 621 is provided on the bottom wall of the guide groove 620. The flip block 60 is movably arranged in the guide groove 620, and a locking member 600 is connected to the flip block 60. The locking member 600 is used to be movably connected in the locking hole 621 to limit the rotation of the flip block 60 in the guide groove 620.

[0046] like Figure 4 As shown, the design of the guide groove 620 effectively limits the rotation direction of the flip block 60 driving the reference block 63 in the fixed seat 62, ensuring that the reference block 63 is stably pressed against the plane portion 11 and the detection column 7 accurately detects the position of the air intake grille 1. At the same time, the locking member 600 is used to cooperate with the locking hole 621 to lock the air intake grille 1. Figure 4 The flip block 60 in the illustrated position (i.e., when pressed against the air intake grille 1) is locked and secured, further ensuring the stability of the structure during testing. It should be noted that the locking member 600 in this embodiment can be a fixing member such as a screw, while the locking hole 621 is a threaded hole. The locking member 600 and the locking hole 621 are threadedly engaged to achieve the locking function of the flip block 60.

[0047] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0048] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0049] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0050] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
