[0002] The automobile crossbeam is a major component of the automobile. There are many mounting holes on the crossbeam. The position accuracy of these mounting holes directly affects the installation of other parts of the automobile.

This utility model is applicable to vehicle crossbeam detection devices, and by providing first and second drive motors to drive the rotation of first and second screw rods, thereby driving the free movement of the slider.

[0004] This technical solution uses a slider to drive the telescopic rod to move freely, thereby completing the detection of the mounting holes on the entire surface of the automobile crossbeam. The entire device is driven by a motor, has high precision, and is simple to operate. The slider moves quickly, which improves the accuracy and speed of detection. However, the holes of the automobile crossbeam are not only opened on the upper surface but also on the left and right sides. When the existing device needs to detect holes on both sides, it is necessary to adjust the position of the crossbeam. In view of this, we propose a high-precision automobile crossbeam detection device. Utility Model Content

A connecting frame 10 is fixedly installed on the outer surface of the limit block 8, and a detection mechanism 11 is fixedly installed on the bottom end of the connecting frame 10. The outer side of the semi-ring gear ring 4 is engaged with a power source 12 for driving the semi-ring gear ring 4 to rotate.

[0025] Based on the above structure,

[0026] In one embodiment, a support leg 13 is fixedly installed at the bottom end of the base 1, and the height of the support leg 13 is greater than the radius of the semi-ring gear ring 4. This arrangement can ensure that the semi-ring gear ring 4 will not contact the ground after rotation. The power source 12 includes a fixed seat 14, and a motor 15 is fixedly installed on the upper surface of the fixed seat 14. The output end of the motor 15 is fixedly installed with a gear 16 that meshes with the semi-ring gear ring 4. This arrangement can drive the semi-ring gear ring 4 to rotate.

[0027] Based on the above structure,

[0028] In one embodiment, the detection mechanism 11 is an image collector 17, which is fixedly mounted on the bottom end of the connecting frame 10. A friction disc 18 extends outward from one side of the base 1. Three positioning holes 19 with an angle of ninety degrees are provided on the surface of the friction disc 18. A spring expansion head 20 adapted to the positioning holes 19 is fixedly mounted on the outer surface of the half-ring gear 16.

At the same time, the lead shaft 6 is set to drive the image collector 17 to move horizontally, thereby being able to take close-range continuous pictures of the beam and compare them with the stored data after combined processing. Compared with shooting from a distance to capture the entire picture of the beam, the detection accuracy can be improved.
