Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile parts detection, especially to a kind of automobile parts detection device based on three-dimensional scanning. BACKGROUND

[0002] In the aspect of automobile parts manufacturing, three-dimensional scanner plays a key role, which can detect the produced parts with high precision, ensuring that its dimensional accuracy and shape accuracy meet the design requirements.

[0003] For some complex-shaped parts, traditional detection methods may be limited, while scanners can easily cope with it, whether it is curved surface or internal cavity detection, accurate results can be obtained, ensuring the overall quality of automobile parts, thereby improving the reliability and safety of the automobile.

[0004] At present, the Chinese patent with the authorization announcement number "CN211085112U" discloses a three-dimensional detection device which has great improvement and innovation compared with traditional devices. When using the three-dimensional detection device, we only need to place the workpiece or part to be detected on the workpiece detection platform. The two sides of the outer wall of the workpiece detection platform are provided with limiting blocks, which can limit and fix the workpiece on the workpiece detection platform. After the parts are placed, we can control the servo air cylinder according to the height of different parts, so as to control the telescopic rod to extend and retract through the servo air cylinder, so that the three-dimensional scanning device can be aligned with the parts to be detected. One side of the rotating connector is provided with an angle adjusting knob, which can be adjusted manually to adjust the scanning angle of the three-dimensional scanning device. After the scanning angle of the three-dimensional scanning device is adjusted, we can start the servo motor, so that the output shaft of the servo motor uniformly drives the connecting bracket to rotate, so as to drive the rolling pulley to roll on the reversing slide rail, so that the rolling bracket can drive the servo air cylinder and the three-dimensional scanning device to perform circular scanning, and finally realize the omnidirectional scanning detection of the parts.

[0005] However, it is after the parts are fixed that the height and angle of the three-dimensional scanning device are adjusted, and then the three-dimensional scanning device rotates around the parts for scanning. Since the angle of the three-dimensional scanning device is fixed during scanning, there will be a scanning dead angle during scanning, which cannot effectively scan the whole part.
