After the automotive parts are installed, the gaps, interlayers, and empty layers between the parts can reach a reasonable space to make the automotive parts meet the integration standards.

[0003] Anti-collision beam components are used in automobile parts. Anti-collision beams can absorb the force generated by the impact when the car collides, reducing the impact force on the occupants of the car. Therefore, anti-collision detection is essential. The detection of anti-collision beams requires the detection of the degree of bending in the structure, the degree of stress resistance, and the rationality of the position of the holes. The degree of bending and the hole position are to enable the anti-collision beam to be installed in accordance with the contour of the car without affecting the installation of other components. However, in the process of anti-collision detection, it is necessary to measure manually with a tape measure. At the same time, the hole position and degree of bending of the anti-collision beams of different cars are different, which makes the detection time-consuming and laborious. Utility Model Content

Example

[0023] Please refer to Figure 1-Figure 5 The utility model proposes a vehicle anti-collision beam 2 inspection tool, comprising a chassis 1, a positioning mechanism 3 for installing the anti-collision beam 2, a guide rail 4 installed on the chassis 1, two positioning mechanisms 3 slidably installed on the guide rail 4 and can be close to or away from each other, and a curvature measuring mechanism 5 is slidably installed on the two positioning mechanisms 3, and the distance between the curvature measuring mechanism 5 and the positioning mechanism 3 is adjustable. The anti-collision beam 2 includes two parts, one is a beam body 22, and the other is a crush box. The distance between the two positioning mechanisms 3 can be adjusted. The two crush boxes of the anti-collision beam 2 are installed corresponding to the two positioning mechanisms 3. At this time, the distance between the two crush boxes can be obtained to ensure that the anti-collision beam 2 can be installed on the car. A curvature measuring mechanism 5 is installed on a positioning mechanism 3, and the distance between the curvature measuring mechanism 5 and the positioning mechanism 3 needs to be set the same. It is measured whether the curvature of the beam body 22 of the anti-collision beam 2 at the same distance from the crush box is the same, or whether the error is qualified, to ensure that the anti-collision beam 2 can be symmetrical or conform to the contour of the car, so as to achieve the effect of rapid detection.

[0024] In a specific embodiment, refer to Figure 3 , Figure 4 , Figure 5 The positioning mechanism 3 includes a sliding base 31 and a positioning plate 32. The positioning plate 32 is fixed on the sliding base 31, and the positioning plate 32 slides on the guide rail 4 through the sliding base 31. The distance adjustment between the positioning mechanisms 3 can be adjusted manually or automatically, and can be achieved by using a cylinder. In the utility model, the guide rail 4 and the sliding base 31 are used. The sliding base 31 can be adjusted manually. The positioning plate 32 on the sliding base 31 corresponds to the installation of the crush box and can imitate the mounting seat of the automobile anti-collision beam 2. After the crush box is installed, the distance between the two crush boxes can be obtained and compared for rapid detection. In the utility model, a roller can also be set on the sliding base 31 to reduce the friction between the sliding base 31 and the guide rail 4.

[0025] In a specific embodiment, refer to Figure 1 , Figure 2 A plurality of bolts are arranged on the positioning plate 32, and the positioning plate 32 is connected to the crush box corresponding to the anti-collision beam 2. The bolts on the positioning plate 32 are used to match the screw holes on the crush box for installation.

[0026] In a specific embodiment, refer to Figure 3 , Figure 4 , a slide rail 33 is installed on the sliding base 31, and the curvature measuring mechanism 5 includes a sliding bracket 51 and a detection mechanism 52. The detection mechanism 52 is installed on the sliding bracket 51 and slides through the slide rail 33. The detection mechanism 52 slides on the slide rail 33 through the sliding bracket 51 to adjust the distance between the detection mechanism 52 and the sliding base 31. The slide rail 33 is parallel to the guide rail 4, and the slide rail 33 is installed on the sliding base 31. At the same time, the slide rail 33 can also be installed on the chassis 1. The slide rail 33 provides an adjustable space for the detection mechanism 52, adjusts the distance between the detection mechanism 52 and the crush box, and detects the curvature of the anti-collision beam 2; in the utility model, the direction of the positioning plate 32 is upward, and the detection mechanism 52 is located above the positioning plate 32.

[0027] In a specific embodiment, refer to Figure 3 , Figure 4 , Figure 5The detection mechanism 52 includes a dial plate 521 and an adjustment seat 522. The adjustment seat 522 is rotatably mounted on the dial plate 521. Two clamping arms 523 are slidably mounted on the adjustment seat 522. The distance between the clamping arms 523 is adjustable and clamps the beam body 22 of the anti-collision beam 2. The connecting line of the two clamping arms 523 is perpendicular to the tangent of the clamped position of the anti-collision beam 2. The distance between the two clamping arms 523 is adjustable. When the position of the detection mechanism 52 is fixed, the position of the dial plate 521 will be fixed. The sliding of the two clamping arms 523 relative to the adjustment seat 522 is linear. Therefore, when the anti-collision beam 2 with a curvature is tightened and clamped, the adjustment seat 522 will be driven to rotate relative to the dial plate 521. At this time, a rotation degree will be formed, which is the curvature, so as to detect whether the curvature of the anti-collision beam 2 is within the curvature range required by the automobile, and prevent the curvature from affecting the installation of other parts of the automobile.

[0028] In a specific embodiment, refer to Figure 5 The adjusting seat 522 is provided with a slide groove 524, and two sliders 525 are slidably installed in the slide groove 524. A rotatable screw rod 526 is installed on the adjusting seat 522, and the screw rod 526 passes through the two sliders 525. Two clamping arms 523 are parallelly installed on the two sliders 525 and clamp the outer arc surface and the inner arc surface of the beam body 22 of the anti-collision beam 2. In the utility model, the distance adjustment of the clamping arms 523 can be achieved by the screw rod 526 slider 525 or the gear rack. In the utility model, the screw rod 526 slider 525 is adopted, and its clamping arms 523 are parallel to the horizontal plane. The material of the clamping arms 523 is rubber material. The clamping arms 523 are respectively located above and below the beam body 22. The two clamping arms 523 clamp the beam body 22 in the middle. When they are close to each other, they clamp the beam body 22. At this time, the connection line of the two clamping arms 523 is perpendicular to the tangent of the curvature of the beam body 22, and the bending angle of the beam body 22 can be obtained.

[0029] In a specific embodiment, refer to Figure 1 , Figure 3 , the guide rail 4 and the slide rail 33 are both provided with length scales. The length scales on the guide rail 4 can obtain the distance data of the positioning mechanism 3 and the detection mechanism 52.

[0030] In a specific embodiment, refer to Figure 5 The dial 521 is provided with degree scales. The degree scales on the dial 521 can obtain the curvature of the beam body 22.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
