Description

Technical Field

[0001] This utility model relates to the field of angle adjustment mechanism technology, and in particular to a carrier for three-dimensional scanning. Background Technology

[0002] Existing devices for 3D scanning mainly include automatic or manual turntables. During rotation, manual turntables may experience slight jamming and vibration, which can easily cause displacement of the scanned object, resulting in ghosting in the scanned data and larger errors in the obtained point cloud data. When scanning some special objects with complex structures, if an automatic turntable is used, the position is fixed and it is difficult to obtain a stable scanning state from multiple angles, which affects the scanning work and makes it impossible to obtain accurate and complete scan data.

Detailed Implementation

[0023] Depend on Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the present invention includes a base plate 1, a connecting plate 2 rotatably connected to the base plate 1, and a support plate 3 rotatably connected to the connecting plate 2 on one side. An adjustment mechanism for adjusting the inclination of the support plate 3 is provided between the other side of the support plate 3 and the connecting plate 2. A positioning component for placing objects is provided in the middle of the support plate 3.

[0024] Specifically, a first connecting boss 10 is provided on the base plate 1, and a first annular groove 11 is provided on the first connecting boss 10. A second connecting boss 20 is provided on the connecting plate 2 at a position corresponding to the first connecting boss 10, and a second annular groove 21 is provided on the second connecting boss 20 at a position corresponding to the first annular groove 11. A sliding assembly is provided between the first annular groove 11 and the second annular groove 21. The first annular groove 11 and the second annular groove 21 form a placement groove in the vertical direction. The sliding assembly includes a connecting block 23 disposed between the first annular groove 11 and the second annular groove 21 and a ball bearing 22 placed on the connecting block 23. A plurality of placement holes 231 are provided on the connecting block 23 along the circumferential direction. A ball bearing 22 is embedded in each placement hole 231. The lower end of each ball bearing 22 is attached to the first annular groove 11, and the upper end of the ball bearing 22 is attached to the second annular groove 21.

[0025] Two lugs 24 protrude from one side of the connecting plate 2, and each lug 24 has a fixing hole 241. A first connecting rod 25 is sleeved between the two fixing holes 241. A notch 30 is provided on the support plate 3 at the position corresponding to the two lugs 24. A connecting boss 31 is provided at the position corresponding to the position between the two lugs 24 at the notch 30. A connecting hole 310 is provided on the connecting boss 31. The connecting boss 31 is rotatably sleeved on the outside of the first connecting rod 25 through the connecting hole 310, so as to realize the rotatable connection of the support plate 3 to the connecting plate 2.

[0026] The adjustment mechanism includes a guide rod assembly disposed on the support plate 3 and a limiting assembly disposed on the connecting plate 2. The guide rod assembly includes a guide rod 4 and a support rod 40 connected to the guide rod 4. A first notch 32 is provided on one side of the support plate 3. Two first fixing blocks 33 are symmetrically disposed in the first notch 32. Each first fixing block 33 is provided with a first mounting hole 331. The two ends of the support rod 40 extend into the corresponding first mounting holes 331.

[0027] The limiting assembly includes a guide block 41 and two second connecting rods 42 symmetrically arranged on the guide block 41. The guide block 41 has a guide hole 411 for the guide rod 4 to pass through and be sleeved. The connecting plate 2 has a second notch 43 at the position corresponding to the guide block 41. Two second fixing blocks 44 are symmetrically arranged in the second notch 43. Each second fixing block 44 also has a second mounting hole 441. The two second connecting rods 42 extend into the corresponding second mounting holes 441. A threaded hole communicating with the guide hole 411 is provided on one side of the guide block 41. A limiting bolt 45 is screwed into the threaded hole. The threaded end of the limiting bolt 45 extends into the guide hole 411 and abuts against the outer wall of the guide rod 4 to achieve the purpose of fixing and limiting the guide rod 4.

[0028] A limiting block 26 protruding from the upper surface of the connecting plate 2 is provided on the side corresponding to the guide rod 4. In use, the upper surface of the limiting block 26 abuts against the lower surface of the support plate 3 so as to limit the downward flipping direction of the support plate 3.

[0029] An opening is provided on one side of the first fixing block 33 corresponding to the position of the first mounting hole 331 and on one side of the second fixing block 44 corresponding to the position of the second mounting hole 441, and the two openings are arranged in the same direction.

[0030] The positioning component includes a pad 5 embedded in the middle of the support plate 3 and protruding from the upper surface of the support plate 3. A placement groove 50 is provided in the middle of the pad 5, and soft clay 51 is filled in the placement groove 50. A latex washer 52 is provided on the pad 5 at the outer position corresponding to the placement groove 50.

[0031] Several calibration points 34 are affixed to the support plate 3; a support block 12 is provided at the lower end of the base plate 1.

[0032] The working principle of this utility model is as follows: like Figure 1 , Figure 4 and Figure 5 As shown, during installation, a first connecting boss 10 is fixed on the base plate 1, and a second connecting boss 20 is fixed on the connecting plate 2 at the position corresponding to the first connecting boss 10. Then, the connecting block 23 and the ball bearing 22 placed on the connecting block 23 are placed between the first connecting boss 10 and the second connecting boss 20, and the lower end of the ball bearing 22 is placed in the first annular groove 11, and the upper end of the ball bearing 22 is placed in the second annular groove 21.

[0033] In this way, when the connecting plate 2 is rotated, the connecting plate 2 is supported in the horizontal direction by the ball bearings 22. The sliding action formed by the ball bearings 22 in the annular groove overcomes the limitation of the displacement range of manual rotation and ensures the smoothness of the rotation of the connecting plate 2. Since the ball bearings 22 are located within the placement groove formed by the two annular grooves, the ball bearings 22 and the connecting block 23 are not easy to fall out under a certain manual rotation force, so as to ensure the stability and safety of use.

[0034] Next, as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the two ends of the support rod 40 are respectively inserted into the corresponding first mounting holes 331 along the opening positions on the first fixing block 33. Then, the guide block 41 is passed through the guide hole 411 and sleeved on the outside of the guide rod 4. The two second connecting rods 42 are respectively inserted into the corresponding second mounting holes 441 along the opening positions on the second fixing block 44. At the same time, the limiting bolt 45 is screwed into the threaded hole on the guide block 41.

[0035] Finally, the placement groove 50 is filled with polymer clay 51, and a latex washer 52 is placed on the pad 5 at the outer position corresponding to the placement groove 50. In this way, the object to be scanned can be inserted and fixed at any angle on the polymer clay 51, and the part of the object to be scanned that exceeds the range of the placement groove 50 is placed on the latex washer 52. The latex washer 52 can also help prevent the object to be scanned from slipping when rotating. In addition, the height difference between the pad 5 and the support plate 3 also helps with the post-processing of the scanning effect.

[0036] When in use, first adjust the support plate 3 to keep it in a horizontal position. Since the outer diameter of the support plate 3 is smaller than the outer diameter of the connecting plate 2, the threaded end of the limiting bolt 45 extends into the guide hole 411 and abuts against the outer wall of the guide rod 4 to achieve the purpose of fixing and limiting the guide rod 4. At this time, the guide rod 4 is in an inclined position. Then place the object on the soft clay 51 or the latex washer 52, and start the scanning operation by manually rotating the connecting plate 2.

[0037] When it is necessary to adjust the tilt angle of the object to be scanned, first loosen the limiting bolt 45, and pull the inclined guide rod 4 upward. Since the connecting boss 31 is rotatably sleeved on the outside of the connecting rod 25 through the connecting hole 310, the support plate 3 is rotatably connected to the connecting plate 2. In this way, the guide rod 4 synchronously drives the support rod 40, the first fixing block 33, and the support plate 3 to rotate upward in a counterclockwise direction. At the same time, the non-connecting end of the guide rod 4 rotates clockwise, thereby synchronously driving the guide block 4. 1. The guide rod 4 rotates in the same direction. Since the guide rod 4 is sleeved on the guide block 41 and the two second connecting rods 42 extend into the corresponding second mounting holes 441, the guide rod 4 can also move axially along the guide hole 411 on the guide block 41 to adapt to the displacement change of the rotation. After the slope is adjusted to the right position, the threaded end of the limiting bolt 45 extends into the guide hole 411 and abuts against the outer wall of the guide rod 4 to achieve the fixed limit of the guide rod 4. Finally, the scanning operation can be started by rotating the connecting plate 2.

[0038] Similarly, in order to help ensure the stability of the horizontal position of the support plate 3, a limiting block 26 is provided on the connecting plate 2 at the position corresponding to the guide rod 4; when in use, the upper end face of the limiting block 26 abuts against the lower end face of the support plate 3 for limiting.

[0039] During this process, since the first fixing block 33 has an opening on one side corresponding to the first mounting hole 331 and the second fixing block 44 has an opening on one side corresponding to the second mounting hole 441, which is convenient for installation, and since the guide rod 4 is in an inclined position during use, coupled with the tightening and limiting of the limiting bolt 45, the support rod 40 cannot be moved out of the first mounting hole 331 under the action of gravity. In order to avoid the guide rod 4 falling out after the limiting bolt 45 is loosened, it is advisable that the two openings face the outside of the connecting plate 2 and are both inclined.

[0040] A support block 12 is provided at the lower end of the base plate 1 so that a gap is maintained between the base plate 1 and the ground (or the table surface of the placement platform) for manual removal and placement.
