[0024] 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.

[0025] like Figure 1 and Figure 2As shown, an embodiment of this application provides an inspection fixture for a rear longitudinal beam assembly of an automobile, including a workbench 1. The workbench 1 is provided with a support mechanism 2 for placing a product, a positioning mechanism 3 for positioning the side end of the product, a clamping mechanism 4 for clamping the product, and a first detection mechanism 5 for inserting and removing holes on the top of the product.

[0026] The support mechanism 2 is provided with several second detection mechanisms 6 for detecting the holes on the bottom of the product, and the workbench 1 is provided with several third detection mechanisms 7 for detecting the holes on the side of the product.

[0027] The positioning mechanism 3 includes two positioning components, which are respectively disposed on both sides of the support mechanism 2 and are used to position the two sides of the product. The positioning components include a plug-in positioning mechanism 31 for positioning the ends of the product and several flip positioning mechanisms 32 for positioning the body of the product.

[0028] Specifically, the rear longitudinal beam assembly of the vehicle is placed on the support mechanism 2. The circular and diamond-shaped locating pins of the support mechanism 2 provide initial positioning of the product. Two insertion and removal locating mechanisms 31 on both sides of the support mechanism 2 position one end of the product, and multiple flipping locating mechanisms 32 on both sides of the support mechanism 2 position the two sides of the product. The clamping mechanism 4 presses the product firmly onto the support mechanism 2, ensuring precise fixation. Then, multiple second detection mechanisms 6 installed on the support mechanism 2 inspect the dimensions of multiple holes on the bottom of the product, the first detection mechanism 5 inspects the dimensions of multiple holes on the top of the product and the top of the extension section, and the third detection mechanism 7 inspects the dimensions of the holes on the two sides of the product. These holes include mounting holes, nut holes, and other types of holes. After the product inspection is completed, the clamping mechanism 4, the insertion and removal locating mechanism 31, and the flipping locating mechanism 32 are released, and the product is removed from the support mechanism 2.

[0029] In the above structure, by setting up a support mechanism 2, a positioning mechanism 3, a clamping mechanism 4, a first detection mechanism 5, a second detection mechanism 6, and a third detection mechanism 7 in cooperation with each other, the positioning, clamping, and dimensional detection of the holes in various parts of the automotive rear longitudinal beam assembly are achieved. This automotive rear longitudinal beam assembly inspection fixture not only meets the inspection requirements of the automotive rear longitudinal beam assembly, but also improves the inspection accuracy and efficiency.

[0030] like Figure 1 and Figure 2As shown, in one embodiment, the first inspection mechanism 5 of the automotive rear longitudinal beam assembly inspection fixture includes several insertion / removal inspection pins 51. These pins are used to inspect the dimensions of the holes on the top of the product. The third inspection mechanism 7 includes a mounting base 71 and several second elastic inspection pins 72. The mounting base 71 is mounted on the workbench 1, and the second elastic inspection pins 72 are mounted on the mounting base 71. These pins are used to inspect the holes on the side of the product. Each second elastic inspection pin 72 includes a detection head, a circular pull head, a pin rod, and a spring. One end of the pin rod passes through the support base 21 and connects to the detection head, while the other end connects to the circular pull head. The spring is sleeved on the pin rod, with one end abutting against the support base 21 and the other end abutting against the circular pull head. After the product is positioned on the support mechanism 2, the insertion / removal inspection pins 51 are manually aligned with multiple holes on the top and extended parts of the product for insertion / removal inspection. Next, the circular pull head of the second elastic detection pin 72 is manually pressed, causing the detection head to extend into the hole in the product, thereby detecting the size of the hole on the side of the product. Releasing the circular pull head allows the detection head to return to its initial position under the force of the spring. This design facilitates the detection of holes on the top and sides of the product, improving detection accuracy.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, the support mechanism 2 of the automotive rear longitudinal beam assembly inspection fixture includes several support seats 21 arranged along the shape of the product. The second inspection mechanism 6 includes several first elastic inspection pins 61, which are respectively mounted on the support seats 21. The first elastic inspection pins 61 pass through the support seats 21 to inspect the dimensions of the holes at the bottom of the product. The first elastic inspection pins 61 and the second elastic inspection pins 62 have the same structure. The insertion / removal positioning mechanism 31 and the flipping positioning mechanism 32 of the positioning mechanism 3 are opened outwards, allowing the product to be placed on the multiple support seats 21. After the positioning mechanism 3 and the clamping mechanism 4 position and clamp the product, the first elastic inspection pins 61 are manually pressed to inspect the dimensions of the holes at the bottom of the product. Releasing the first elastic inspection pins 61 allows them to return to their initial positions under the force of the springs. This support mechanism 2 facilitates product support. The second inspection mechanism 6 facilitates the inspection of the holes at the bottom of the product, improving inspection accuracy.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the support base 21 of the automotive rear longitudinal beam assembly inspection fixture is provided with circular and diamond-shaped locating pins for positioning the product. The circular and diamond-shaped locating pins facilitate product positioning, ensuring the accuracy of product placement and thus ensuring the accuracy of inspection.

[0033] like Figure 3 As shown, in one embodiment, the insertion and removal positioning mechanism 31 of the automotive rear longitudinal beam assembly fixture includes a first positioning plate 311 and an insertion and removal mechanism 312. The driving end of the insertion and removal mechanism 312 is connected to the first positioning plate 311. The first positioning plate 311 is provided with a first detection pin 313 for detecting the hole positions on the side end of the product. The insertion and removal mechanism 312 drives the first positioning plate 311 to move the first detection pin 313 back and forth. When the product is placed on the support mechanism 2, the insertion and removal mechanism 312 drives the first positioning plate 311 to move towards the product to position the side end of the product. The first detection pin 313 on the first positioning plate 311 detects the hole positions at the corresponding part of the product. This arrangement facilitates the positioning of the end of the product, and the detection pin can be used to detect the hole positions at the end.

[0034] like Figure 3 As shown, in one embodiment, the insertion / removal mechanism 312 of the automotive rear longitudinal beam assembly inspection fixture includes a fixed base 001, a fixed block 002, an insertion / removal block 003, and a fixing pin 004. The fixed block 002 is mounted on the fixed base 001 and has a through hole for sliding the insertion / removal block 003 and the fixing pin 004. The insertion / removal block 003 has a first fixing hole and a second fixing hole 006 that are fixedly engaged with the fixing pin 004. Manually pulling the insertion / removal block 003 outwards causes the first fixing plate to move outwards, facilitating the placement of the product on the support mechanism 2. Once the product is in place, manually pushing the insertion / removal block 003 moves the first fixing plate towards the product to position the end of the product. After being pushed to the designated position, the fixing pin 004 moves forward and extends into the second fixing hole 006 of the insertion / removal block 003, fixing the positioning position of the insertion / removal block 003. When the plug-in block 003 is pulled open to the position of the first fixing hole, the fixing pin 004 can be fixedly engaged with the first fixing hole to realize the positioning operation of the first positioning plate 311 at different positions. The plug-in mechanism 312 is designed to facilitate the driving of the first positioning plate 311 to perform positioning and opening operations on the product.

[0035] like Figure 4 As shown, in one embodiment, the flipping and positioning mechanism 32 of the automotive rear longitudinal beam assembly fixture includes a second positioning plate 321 and a flipping mechanism 322. The driving end of the flipping mechanism 322 is connected to the second positioning plate 321, and the flipping mechanism 322 is used to drive the second positioning plate 321 to perform a flipping operation. When the product needs to be placed on the support mechanism 2, the flipping mechanism 322 drives the second positioning plate 321 to flip outward away from the support mechanism 2. After the product is placed in place, the flipping mechanism 322 drives the second positioning plate 321 to move towards the product to position the side end of the product. This arrangement facilitates the positioning of both sides of the product and improves the positioning effect.

[0036] like Figure 4As shown, in one embodiment, the flipping mechanism 322 of the automotive rear longitudinal beam assembly fixture includes a connecting seat 007, a flipping plate 008, and a locking pin 009. The connecting seat 007 is mounted on the workbench 1. One end of the flipping plate 008 is hinged to the connecting seat 007, and the locking pin 009 passes through the flipping plate 008 and is threadedly connected to the connecting seat 007. The other end of the flipping plate 008 is connected to the second positioning plate 321. Loosening the locking pin 009 allows the flipping plate 008 to flip outwards around the connecting seat 007 and open. After the product is placed, the flipping plate 008 drives the second positioning plate 321 to flip around the connecting seat 007 towards the product to position it. Then, rotating the locking pin 009 locks the flipping plate 008 onto the connecting seat 007. This arrangement facilitates the operation of driving the second positioning plate 321 to position and open the product.

[0037] like Figure 1 and Figure 2 As shown, in one embodiment, the clamping mechanism 4 of the automotive rear longitudinal beam assembly inspection fixture includes several first clamps 41 for clamping the product body and several second clamps 42 for clamping the outwardly expanding parts of the product. The first clamps 41 and the second clamps 42 are respectively mounted on the workbench 1. The multiple first clamps 41 clamp and fix the product body, and the multiple second clamps 42 clamp and fix the outwardly expanding parts of the product. This arrangement prevents product displacement during the inspection process.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, a support frame 8 is provided under the workbench 1 of the automotive rear longitudinal beam assembly inspection fixture. The bottom of the support frame 8 is provided with four support legs 9 and four casters 10 with brake assemblies. The support frame 8 and the four support legs 9 improve the support strength and stability of the workbench 1. The casters 10 facilitate the movement of the inspection fixture.

[0039] 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.
