[0030] like Figures 1-5As shown, this utility model provides a technical solution: a three-dimensional scanning device, including a scanning component 1, which is composed of a sliding adjustment base 11 and a camera mechanism 13. The camera mechanism 13 is disposed at the bottom of the sliding adjustment base 11, and further includes:

[0031] Adjustment component 2 consists of sliding seat 22, scanning component 1, and sliding seat 22. Sliding adjustment seat 11 is slidably connected to arc-shaped adjustment frame 21. There are two sliding seats 22, which are respectively located at the bottom of arc-shaped adjustment frame 21. A sleeve 23 is provided between the two sliding seats 22. A gear disk 24 is provided at the bottom of the sleeve 23. A connecting rod 25 is provided between the sleeve 23 and the two sliding seats 22. The arc-shaped adjustment frame 21 has a toothed groove 211. The toothed groove 211 is distributed in a ring, and the included angle between two adjacent toothed grooves 211 is equal. The gear disk 24 at the bottom of the sleeve 23 meshes with an external drive gear 36. When the drive gear 36 rotates, it drives the gear disk 24 and the sleeve 23 to rotate, and then pulls the two sliding seats 22 to slide synchronously along the toothed groove 211 through the connecting rod 25. Meanwhile, the sliding adjustment seat 11 can slide independently on the arc-shaped adjustment frame 21 to adjust the radial position of the scanning component 1, realizing flexible adjustment of the scanning component 1 in both horizontal circumference and radial dimensions, so that the scanning component 1 can drive the gear to scan 360° around, eliminating scanning blind spots.

[0032] A hub motor 12 is embedded at one end of the sliding adjustment seat 11 located on the top of the arc-shaped adjustment frame 21. An adjustment gear 14 is provided at the output end of the hub motor 12. The adjustment gear 14 is meshed with the tooth groove 211. The sliding adjustment seat 11 and the arc-shaped adjustment frame 21 are linked through the hub motor 12 and the adjustment gear 14. The hub motor 12 drives the adjustment gear 14 to rotate. Because it meshes with the tooth groove 211 of the arc-shaped adjustment frame 21, the sliding adjustment seat 11 can slide precisely along the arc trajectory. Functionally, this design allows the scanning head to flexibly adjust its position along the arc path, expanding the scanning angle in the horizontal direction.

[0033] The bottom of the sliding seat 22 is provided with a rotating component 3, which consists of a slide rail seat 31 and a base 32. A support rod 321 is provided between the slide rail seat 31 and the base 32. The support rods 321 are arranged in a ring, and the distance between two adjacent support rods 321 is equal. The rotating component 3 at the bottom of the sliding seat 22 adopts a layered design. The slide rail seat 31 and the base 32 are connected by the ring-shaped equally spaced support rods 321 to form a stable support structure. When the drive system is started, the slide rail seat 31 can rotate 360° relative to the base 32 around the central axis, driving the upper sliding seat 22 and the scanning component 1 to rotate synchronously.

[0034] A support column 33 is provided on the top of the base 32, penetrating the slide rail seat 31. A placement platform 34 is provided on the top of the support column 33. The diameter of the placement platform 34 is smaller than the diameter of the inner wall of the slide rail seat 31.

The placement platform 34 is located at the top of the support column 33, and its diameter is smaller than the inner wall of the slide rail seat 31, ensuring that the slide rail seat 31 can rotate freely around the support column 33 without interfering with the placement platform 34. When the slide rail seat 31 rotates under the action of the drive system, the placement platform 34 remains stationary. The object to be scanned is placed on it, and the scanning assembly 1 rotates synchronously with the slide rail seat 31, forming a circular scanning path around the object. Combined with the scanning head on the arc-shaped adjustment frame 21... The radial sliding mechanism enables spiral three-dimensional data acquisition. An annular slide rail 311 is located on the top of the slide rail base 31. The arc-shaped adjustment frame 21 is slidably connected to the annular slide rail 311 via the slide seat 22. A rotating shaft 35 is provided between the slide rail base 31 and the base 32. A drive gear 36 is mounted on the rotating shaft 35 and meshes with a gear disk 24. The annular slide rail 311 on the top of the slide rail base 31 provides a radial sliding track for the slide seat 22. The drive gear 36 meshes with the gear disk 24 fixed to the bottom of the slide rail base 31, forming an external meshing gear transmission pair. When the drive gear 36 rotates, the tooth surface contact force drives the gear disk 24, along with the slide rail base 31, to perform a circular motion around the rotating shaft 35, thus achieving a 360° rotation of the drive gear of the scanning component 1.

[0035] A drive motor 37 is provided at the bottom of the base 32. The output end of the drive motor 37 is connected to the rotating shaft 35. The drive motor 37 at the bottom of the base 32 serves as a power source and converts electrical energy into mechanical energy after being powered on.
