Description

Technical Field

[0001] This utility model relates to the field of longitudinal beam processing technology, specifically to a quality inspection device for automobile longitudinal beam processing. Background Technology

[0002] In the automotive manufacturing industry, the longitudinal beam, as a critical structural component, plays a decisive role in the overall safety and stability of a vehicle. Its processing quality not only affects the assembly precision of the vehicle but also its load-bearing capacity and impact resistance during operation. With the rapid development of the automotive industry, the market has placed higher demands on the quality and safety of automobiles. Therefore, strict control over the processing quality of automotive longitudinal beams has become an indispensable part of the automotive production process.

[0003] In the automotive manufacturing industry, the longitudinal beam, as a critical structural component, directly affects the overall safety and stability of a vehicle. Its processing quality not only influences the assembly precision of the vehicle but also plays a decisive role in its load-bearing capacity and impact resistance during operation. With the rapid development of the automotive industry, the market has raised the bar for vehicle quality and safety, making strict control over the processing quality of automotive longitudinal beams an indispensable part of the automotive production process.

[0004] Traditional methods for inspecting the quality of automotive longitudinal beams have many drawbacks. Early methods relied primarily on manual inspection, with workers using simple measuring tools to take dimensional measurements and visually inspecting surface quality. This approach is not only inefficient and unable to meet the demands of large-scale production, but its accuracy is also highly susceptible to human error, easily leading to missed or false positives. Even with the introduction of some automated inspection equipment, some devices can only perform single-dimensional inspections, such as checking dimensional accuracy or surface quality, failing to provide a comprehensive quality assessment of the longitudinal beams.

[0005] Furthermore, some existing testing equipment struggles to adapt to the rapid switching between testing longitudinal beams of different specifications. When automakers launch different car models to meet diverse market demands, the specifications of the longitudinal beams also change. Traditional testing equipment often requires significant time for equipment adjustments and parameter resetting in such situations, severely impacting production efficiency. Moreover, traditional testing equipment has weak data management and analysis capabilities, failing to effectively integrate and deeply analyze large amounts of testing data, which hinders quality traceability and continuous improvement during the production process.

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] Example 1

[0028] like Figure 1-4 As shown, this utility model provides a quality inspection device for the processing of automotive longitudinal beams, including a track 1, a mounting frame 2 is provided above the track 1, a camera mounting frame 10 is fixedly connected to the top of the mounting frame 2, and a vision inspection camera 9 is fixedly connected to the bottom surface of the camera mounting frame 10 near both ends.

[0029] A lifting hydraulic rod 3 is fixedly connected to the center of the bottom surface of the mounting frame 2 near one side. A support base 4 is attached to the bottom surface of the mounting frame 2. An extension rod 7 is fixedly connected to one side of the mounting frame 2. A laser displacement sensor 8 is fixedly connected to one end of the extension rod 7. A laser displacement sensor 11 is fixedly connected to the top of the inner wall of the mounting frame 2.

[0030] Both sides of the visual inspection camera 9 are fixedly connected to probe adjustment brackets 13, and probes 12 are arranged below the probe adjustment brackets 13. The probe adjustment brackets 13 adjust the relative position of probes 12 through position adjustment components.

[0031] The position adjustment assembly includes a built-in hydraulic rod 14, which is fixedly connected to the inner wall of the probe adjustment frame 13. The extended end of the built-in hydraulic rod 14 is fixedly connected to a height adjustment hydraulic rod 15 via a mounting block. The extended end of the height adjustment hydraulic rod 15 is fixedly connected to a connector 16, and the inner wall of the connector 16 is fixedly connected to the outer wall of one end of the probe 12.

[0032] Example 2

[0033] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, an ultrasonic flaw detector 6 is fixedly connected to one side of the extension rod 7.

[0034] The bottom surface of the mounting bracket 2 is fixedly connected to a guide slide rod 5, and one side of the guide slide rod 5 is slidably connected to the inner wall of the supporting base 4.

[0035] There are four sets of probes 12, which are symmetrically distributed on both sides of the mounting bracket 2.

[0036] There are four sets of laser displacement sensors 8, symmetrically distributed on both sides of the mounting frame 2. There are also four sets of laser displacement sensors 11, symmetrically distributed on the top of the inner wall of the mounting frame 2.

[0037] The working principle of the quality inspection device for the machining of automotive longitudinal beams will be explained in detail below.

[0038] like Figure 1-4 As shown, for size and shape detection: the longitudinal beam is conveyed into the detection area via conveyor belt 1. Laser displacement sensor 8 and laser displacement sensor 11 scan and measure various key parts of the longitudinal beam according to a preset program, and the measurement data is transmitted to the control system in real time. The control system analyzes and compares the measurement data based on preset standard dimensional parameters to determine whether the dimensional accuracy and shape of the longitudinal beam meet the requirements. During the conveying process of the longitudinal beam, laser displacement sensor 8 and laser displacement sensor 11 also continuously monitor the key position data to prevent deformation during the conveying process from affecting the detection results.

[0039] Surface quality inspection: The visual inspection camera 9 begins capturing images when the longitudinal beam enters the inspection area, recording the initial surface condition. Within the inspection area, the camera continuously captures comprehensive images of the longitudinal beam surface, which are then transmitted to image analysis software. The software uses image recognition algorithms to compare the captured images with standard images, identifying surface defects such as scratches and cracks, and marking and recording the location and size of these defects. When the longitudinal beam leaves the inspection area, the camera captures images again to ensure that no new surface defects are added throughout the entire inspection process.

[0040] Internal quality inspection: The ultrasonic flaw detector 6 emits ultrasonic waves through probe 12 into the longitudinal beam. When the ultrasonic waves propagate inside the longitudinal beam, they encounter defects and undergo reflection, refraction, and scattering. The flaw detector receives the reflected ultrasonic signals and, based on the characteristics and intensity of the signals, determines whether defects exist inside the longitudinal beam, as well as the type, location, and size of the defects. Multiple probes 12 work together to ensure that the internal quality of all parts of the longitudinal beam can be effectively inspected.

[0041] During the inspection process, the control system adjusts according to the specifications of the longitudinal beam. By activating the lifting hydraulic rod 3, the lifting hydraulic rod 3 pushes the mounting frame 2 upward, thereby driving the laser displacement sensor 11, probe 12, laser displacement sensor 8 and visual inspection camera 9 to rise, and vice versa.

[0042] During the detection process, the probe 12, with the cooperation of the built-in hydraulic rod 14 and the height-adjusting hydraulic rod 15, can flexibly change the height of the probe 12 and the distance between it and the longitudinal beam, thereby improving the comprehensiveness of the detection.

[0043] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
