Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2As shown, an embodiment of this application provides a vehicle rear wheel arch inner panel assembly inspection fixture, including a workbench 1. The workbench 1 is provided with a support mechanism 2 for supporting the product, a clamping mechanism 3 for clamping and fixing the product, and an inspection mechanism 4 for inspecting the product. The support mechanism 2 is provided with a contour inspection table 5 for placing the product. The clamping mechanism 3 is installed on the support mechanism 2. The inspection mechanism 4 is installed on the workbench 1. The inspection mechanism 4 includes a first inspection pin mechanism 41 for inspecting multiple holes and multiple studs at the middle position of the top of the product, a second inspection pin mechanism 42 for inspecting two studs at the top side of the product, a third inspection pin mechanism 43 for inspecting multiple studs at the bottom of the product, and a fourth inspection pin mechanism 44 for inspecting the holes at the bottom of the product.

[0025] Specifically, the contour testing platform 5 is mounted on the support mechanism 2. At the start of the test, the first and second detection pin mechanisms 41 and 42 are in the open state. The product is placed on the contour testing platform 5, where two positioning pins 51 precisely position it. After the product is in place, the clamping mechanism 3 clamps all parts of the product to ensure its stability during the test. Subsequently, the third and fourth detection pin mechanisms 43 and 44 inspect the studs and holes at the bottom of the product. Simultaneously, the first and second detection pin mechanisms 41 and 42 flip downwards to inspect the studs and holes at the top of the product.

[0026] In the above structure, the support mechanism 2 and the contouring inspection table 5 work together to achieve stable support and precise positioning of the product. The clamping mechanism 3 clamps the product on the contouring inspection table 5, further ensuring product stability during inspection and thus improving inspection accuracy. The first detection pin mechanism 41, the second detection pin mechanism 42, the third detection pin mechanism 43, and the fourth detection pin mechanism 44 work together to inspect the studs and holes in various parts of the product. By setting up the support mechanism 2, the contouring inspection table 5, the clamping mechanism 3, and the inspection mechanism 4 in tandem, precise positioning, stable clamping, and all-around inspection of the product are achieved, improving inspection accuracy.

[0027] like Figure 3 and Figure 7As shown, in one embodiment, the first detection pin mechanism 41 of the automotive rear wheel arch inner panel assembly inspection fixture includes a first flipping mechanism 411 and a first detection pin assembly 412. The first flipping mechanism 411 is mounted on the workbench 1. A nitrogen spring 413 for buffering the first detection pin assembly 412 is provided on the side end of the first flipping mechanism 411. The first detection pin assembly 412 is mounted on the first flipping mechanism 411. The first detection pin assembly 412 includes a plurality of stud detection pins 100 and a plurality of hole detection pins 101. The stud detection pins 100 are provided with a first detection groove 001 for detecting the stud size. The hole detection pins 101 are provided with a first detection head 005 for extending into the product hole to detect the size of the product hole. The drive end of the first flipping mechanism 411 is connected to the first detection pin assembly 412. The first detection pin assembly 412 includes one stud detection pin 100 and five hole detection pins 101. Once the product is in place, the first detection pin assembly 412 flips downwards via the first flipping mechanism 411, allowing the studs on the product to enter the detection slots of the stud detection pins 100. If the studs smoothly extend into the detection slots, their dimensions meet the requirements; if they cannot extend, they are deemed unqualified. Simultaneously, the five hole detection pins 101 are aligned with the five holes on the product for detection. If the first detection head 005 of the hole detection pin 101 can smoothly extend, the hole is qualified; if it cannot extend, it is deemed unqualified. Because the first detection pin assembly 412 integrates one stud detection pin 100 and five hole detection pins 101, its overall structure is relatively large. Therefore, a nitrogen spring 413 is installed on the side of the first flipping mechanism 411 to provide cushioning force for the first detection pin assembly 412, ensuring a smooth and accurate flipping process while reducing impact on the inspection tool and the product. This design facilitates the detection of studs and holes in the middle of the top of the product.

[0028] like Figure 4 As shown, in one embodiment, the second detection pin mechanism 42 of the automotive rear wheel arch inner panel assembly inspection fixture includes two second detection pin assemblies 421 arranged along the top studs of the product. Each second detection pin assembly 421 includes a second flipping mechanism 102 and a second detection pin 103. The second flipping mechanism 102 is mounted on the workbench 1 and connected to the second detection pin 103. The second detection pin 103 has a second detection groove 002. The second flipping mechanism 102 drives the second detection pin 103 to detect the dimensions of the product studs. The driving end of the second flipping mechanism 102 is connected to the second detection pin 103, and the second detection pin 103 flips downwards through the second flipping mechanism 102 to detect the studs on the top side of the product. If the stud can smoothly extend into the second detection groove 002 of the second detection pin 103, its dimensions are deemed acceptable; otherwise, it is deemed unacceptable. This design ensures the accuracy and ease of operation in detecting the studs on the top side of the product.

[0029] like Figure 5 As shown, in one embodiment, the third inspection pin mechanism 43 of the automotive rear wheel arch inner panel assembly inspection fixture includes several third inspection pin assemblies 431. Each third inspection pin assembly 431 includes a fixing seat 104 and a third inspection pin 105. The third inspection pin 105 is mounted on the fixing seat 104 and has a third inspection groove 003, which is used to inspect the dimensions of the product's studs. The third inspection pin mechanism 43 consists of seven third inspection pin assemblies 431. The fixing seats 104 of four third inspection pin assemblies 431 are respectively connected to the support mechanism 2, and the fixing seats 104 of the other three third inspection pin assemblies 431 are mounted on the worktable 1. When the product is placed on the contour inspection table 5, the seven third inspection pins 105 inspect the seven studs on the bottom of the product. If the studs can be smoothly inserted into the third inspection groove 003 of the third inspection pin 105, their dimensions are deemed acceptable; otherwise, they are deemed unacceptable. This setup not only enables efficient inspection of the studs at the bottom of the product, but also ensures the accuracy of the inspection process and the reliability of the results.

[0030] like Figure 6 As shown, in one embodiment, the fourth detection pin mechanism 44 of the automotive rear wheel arch inner panel assembly inspection fixture includes several fourth detection pin assemblies 441. Each fourth detection pin assembly 441 includes a mounting base 106 and a fourth detection pin 107. The fourth detection pin 107 is mounted on the mounting base 106 and is provided with a second detection head 004 for dimensional detection of the holes at the bottom of the product. The fourth detection pin mechanism 44 consists of one fourth detection pin assembly 441, and the mounting base 106 of the fourth detection pin assembly 441 is connected to the support mechanism 2. When the product is placed on the contour inspection table 5, the second detection head 004 of the fourth detection pin 107 detects the holes at the bottom of the product. If the detection head of the fourth detection pin 107 can smoothly extend into the hole at the bottom of the product, the hole is qualified; if it cannot extend, it is determined to be unqualified. This setting facilitates the detection of the holes at the bottom of the product and improves the accuracy of the detection.

[0031] like Figure 2As shown, in one embodiment, the support mechanism 2 of the automotive rear wheel arch inner panel assembly inspection fixture includes multiple support seats 21, which provide all-around support for the product. The contouring inspection table 5 is equipped with positioning pins 51 for positioning the product. The support mechanism 2 consists of six support seats 21, which are rationally arranged according to the product's structural characteristics to provide stable all-around support. This support mechanism 2 provides uniform and reliable support for the product. The positioning pins 51 further improve the product's positioning accuracy, enabling the product to be placed quickly and accurately onto the contouring inspection table 5.

[0032] like Figure 2 As shown, in one embodiment, the clamping mechanism 3 of the automotive rear wheel arch inner panel assembly inspection fixture includes multiple clamps 31, which are respectively mounted on the support mechanism 2. The clamps 31 are used to clamp various parts of the product. The clamping mechanism 3 consists of four clamps 31, which are mounted on the support mechanism 2 along the circumference of the product. After the product is placed in position, the four clamps 31 clamp various parts of the product. This arrangement further ensures the stability of the product during inspection, thereby improving inspection accuracy.

[0033] like Figure 1 As shown, in one embodiment, the bottom of the worktable 1 of the automotive rear wheel arch inner panel assembly inspection fixture is provided with a support frame 6 for supporting the worktable 1. The provision of the support frame 6 facilitates increasing the inspection height and support strength of the worktable 1.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
