[0002] The right longitudinal beam assembly is a core component of a vehicle's structure, playing a crucial role in its safety and stability. Typically located in the center of the chassis, it extends longitudinally along the vehicle, working in conjunction with crossbeams and other structural elements to form a robust support system. The right longitudinal beam assembly is generally made of steel or aluminum alloy, with cross-sectional shapes often being channel-shaped, Z-shaped, or box-shaped to accommodate different structural requirements. The front longitudinal beam is located below the engine compartment at the front of the vehicle, supporting the weight of the front end; the rear longitudinal beam is located below the trunk at the rear, stabilizing the rear structure. The longitudinal beam assembly not only bears the weight of the vehicle body but also transmits various forces generated during driving, ensuring the vehicle's stability and rigidity. To ensure the right longitudinal beam assembly is assembled correctly, it needs to be inspected during production.

Then, place the workpiece to be tested on top of the positioning mechanism 5 according to the shape and position of the fixed contour plate 608. The positioning mechanism 5 positions and fixes the workpiece. During positioning, adjust the workpiece position appropriately so that the side wall contour of the workpiece matches the contour of the fixed contour plate 608 and maintains a certain gap. Then, close the clamping clamp 7 to further press and fix the workpiece to be tested. Then, rotate the rotating plate 603 so that the connecting plate 606, the contour detection block 604, and the movable contour plate 607 move toward the workpiece until the contour detection is completed. Block 604 is attached to the surface of the workpiece, while the movable contour plate 607 maintains a certain gap with the surface of the workpiece. Then, a detection pin is inserted into the corresponding detection hole 605 to detect the position of the hole on the workpiece surface. If the detection part of the detection pin can be inserted into the hole of the product, it is qualified; otherwise, it is unqualified. Next, the corresponding scribing pin is inserted into the corresponding hole of the workpiece to scribing, and the offset direction is determined. Then, the offset is measured with calipers. Finally, a go / no-go gauge is inserted into the gap between the workpiece and the fixed contour plate 608 and the movable contour plate 607. If the go end of the go / no-go gauge passes through and the stop end stops, the profile of the workpiece is qualified; otherwise, it is unqualified.

[0024] refer to Figure 3-4The positioning mechanism 5 includes a positioning seat 501. A sleeve 502 is fixedly connected to the top of the positioning seat 501. A pair of connecting shafts 504 are fixedly connected horizontally and symmetrically to the side wall of the sleeve 502. The pair of connecting shafts 504 are coaxially arranged. A flipping frame 505 is slidably and rotatably connected to the outside of the pair of connecting shafts 504. The flipping frame 505 is U-shaped. A handle 506 is fixedly connected to the side of the flipping frame 505 away from the sleeve 502. A first waist-shaped opening is formed at the connection between the flipping frame 505 and the connecting shafts 504. Groove 507; A movable shaft 508 is arranged parallel to the lower side of the connecting shaft 504. The movable shaft 508 horizontally passes through the sleeve 502. A pair of second waist-shaped grooves 509 are provided at the connection between the sleeve 502 and the movable shaft 508. The movable shaft 508 is slidably connected to the sleeve 502 through the second waist-shaped grooves 509. A pair of retaining rings are symmetrically fixed to both ends of the movable shaft 508. The pair of retaining rings are respectively arranged on both sides of the flipping frame 505. The flipping frame 505 is arc-shaped on both sides of the end facing the sleeve 502. 05. The two side walls of one end of the sleeve 502 are slidably connected to the movable shaft 508; a positioning platform 503 is fixedly connected to the top of the sleeve 502, and a through groove 515 is opened on the side wall of the positioning platform 503; a pair of movable plates 512 are symmetrically rotatably connected to the middle of the movable shaft 508; a pair of buckles 514 are symmetrically fixedly connected to the top of the pair of movable plates 512, and the pair of buckles 514 extend to the outside of the two sides of the through groove 515 respectively; a limit shaft 510 is provided parallel to the top of the pair of connecting shafts 504. 510 passes through the middle of a pair of movable plates 512 and is fixedly connected to the sleeve 502. A pair of limiting grooves 513 are symmetrically provided at the connection between the side walls of the pair of movable plates 512 and the limiting shaft 510. The limiting shaft 510 is slidably connected to the movable plates 512 through the limiting grooves 513. The bottom of the limiting grooves 513 is inclined downward in a direction away from the axis of the sleeve 502. An elastic top platform 511 is fixedly connected to the top center of the positioning seat 501. The top of the elastic top platform 511 abuts against the bottom of the pair of movable plates 512.During positioning, the initial position of the buckle 514 is inside the through groove 515, the pair of movable plates 512 are in the closed state, and the movable shaft 508 is located at the top of the second waist-shaped groove 509 under the elastic force of the elastic top block 511. At this time, the workpiece to be tested is placed on the top of the positioning mechanism 5, so that the positioning table 503 is inserted into the positioning hole corresponding to the bottom of the workpiece until the workpiece abuts against the top of the sleeve 502, thus limiting the workpiece to be tested. Then, the handle 506 is turned downwards, so that the flipping frame 505 rotates downwards around the connecting shaft 504. When the flipping frame 505 rotates, a relative movement is generated between the first waist-shaped groove 507 and the connecting shaft 504. Simultaneously, the side wall of the flipping frame 505 and the movable shaft 508 move relative to each other, exerting downward pressure on the movable shaft 508. This causes the movable shaft 508 to move downward along the second waist-shaped groove 509. As the movable shaft 508 moves downward, it also causes the movable plate 512 in the middle to move downward. When the movable plate 512 moves downward, it causes the limiting groove 513 and the limiting shaft 510 to slide relative to each other, causing the movable plate 512 to open during its downward movement. This causes the buckle 515 at the top of the movable plate 512 to extend along both sides of the through groove 515 during its downward movement, thus fixing the workpiece outside the positioning table 503.

[0025] refer to Figure 7 The bottom of the base 1 is rotatably connected to several rollers 8, and the side wall of the base 1 is fixedly connected to a pull rod 9. By providing the pull rod 9 and rollers 8, the position of the inspection tool can be easily moved, improving the flexibility of the inspection tool's use.

[0026] Working principle: Before testing, ensure that the positioning mechanism 5, the testing mechanism 6, and the clamp 7 are all in the open state. Then, according to the shape and position of the fixed contour plate 608, place the workpiece to be tested on the top of the positioning mechanism 5. The positioning mechanism 5 positions and fixes the workpiece to be tested. During positioning, the initial position of the buckle 514 is located inside the through groove 515, a pair of movable plates 512 are in the closed state, and the movable shaft 508 is located at the top of the second waist-shaped groove 509 under the elastic force of the elastic top block 511. At this time, place the workpiece to be tested on the top of the positioning mechanism 5, so that the positioning table 503 is inserted into the positioning hole corresponding to the bottom of the workpiece until the workpiece abuts against the top of the sleeve 502, limiting the workpiece to be tested. Then, turn the handle 506 downward, so that the flipping frame 505 rotates downward around the connecting shaft 504. When the flipping frame 505 rotates, the first waist-shaped groove 507 and the connecting shaft 504 are connected. A relative motion is generated between 04, and at the same time, a relative motion is generated between the side wall of the flipping frame 505 and the movable shaft 508, which exerts downward pressure on the movable shaft 508, causing the movable shaft 508 to move downward along the second waist-shaped groove 509. When the movable shaft 508 moves downward, it drives the movable plate 512 in the middle to move downward. When the movable plate 512 moves downward, it causes the limiting groove 513 and the limiting shaft 510 to slide relative to each other, so that the movable plate 512 opens during the downward movement, and the buckle 515 at the top of the movable plate 512 extends along both sides of the through groove 515 during the downward movement, fixing the workpiece outside the positioning table 503. During the positioning process, the position of the workpiece is adjusted appropriately so that the contour of the side wall of the workpiece matches the contour of the fixed contour plate 608 and maintains a certain gap. Then the clamp 7 is closed to further press and fix the workpiece to be tested.

[0027] During inspection, rotating plate 603 causes connecting plate 606, contour detection block 604, and movable contour plate 607 to move towards the workpiece until contour detection block 604 is in contact with the workpiece surface. At this time, movable contour plate 607 maintains a certain gap with the workpiece surface. Then, a detection pin is inserted into the corresponding detection hole 605 to check the position of the hole on the workpiece surface. If the detection part of the detection pin can be inserted into the hole of the product, it is qualified; otherwise, it is unqualified. Next, the corresponding scribing pin is inserted into the corresponding hole of the workpiece to scribing, and the offset direction is determined. Then, the offset is measured with calipers. Finally, a go / no-go gauge is inserted into the gap between the workpiece and the fixed contour plate 608 and the movable contour plate 607. If the go end of the go / no-go gauge passes through and the stop end stops, the profile of the workpiece is qualified; otherwise, it is unqualified.

[0028] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
