Technical Field

[0001] The utility model relates to the technical field of scanning measurement, in particular to a scanning measuring instrument. Background Art

[0002] Scanning measurement is a method of non-contact measurement and data collection of objects using advanced technical means. Scanning measurement instruments usually use optical, laser, ultrasonic and other technologies to obtain the three-dimensional coordinate information of the object surface by emitting specific signals and receiving signals reflected or scattered back by the object, thereby constructing a three-dimensional model of the object.

[0003] When existing equipment is in use, the measuring body is usually installed in a fixed position, which limits the measuring range of the measured object and has a serious impact on the accuracy of the measurement results. In addition, the placement of the measured object is best centered, and it is difficult to ensure its centering degree by naked eye observation alone. Utility Model Content

The cross-section of the placement seat 3 is set to a circular shape. The center of the first gear ring 5 coincides with the center of the placement seat 3. By setting a rotating mechanism, the object to be measured is placed on the top of the placement seat 3 and positioned at the center of the placement seat 3. The first gear 6 is rotated. Due to the meshing connection between the first gear 6 and the first gear ring 5, the first gear ring 5 rotates, causing the rotating rod 4 to drive the measuring body 1 to rotate. Since the center of the first gear ring 5 coincides with the center of the placement seat 3, the measuring body 1 rotates around the object to be measured and performs scanning measurement at the same time, thereby making the scan data more accurate.

[0032] It is worth noting that the measuring subject 1 is a small scanning measuring instrument, such as the axe-b17 global 3D scanner;

[0033] Reference Figure 1-4 , the centering mechanism includes a slide 7 and a slider 8, the slide 7 is opened inside the placement seat 3, the slider 8 is slidably installed inside the slide 7, the top of the slide 7 is provided with a limit groove 15, the limit block 16 is slidably installed inside the limit groove 15, the limit block 16 is slidably sleeved inside the slider 8, the height of the top of the limit block 16 is lower than the height of the top of the placement seat 3, the inner wall of the limit groove 15 is provided with a guide groove 17, the guide groove 17 is slidably installed with a guide shaft 18, the guide shaft 18 and the limit block 16 are fixedly connected, by setting the centering mechanism, through the cooperation of the slide 7, the slider 8 can only move along the direction of the slide 7, through the slider 8 The movement drives the limit block 16 to move inside the limit groove 15. Since part of the shape of the change groove is set to be inclined, the change shaft is squeezed by the inner wall of the change groove, so that the change shaft drives the limit block 16 to move close to the central axis of the placement seat 3. At the same time, the limit block 16 also moves upward, so that the top of the limit block 16 penetrates the top of the placement seat 3 and continues to extend upward, thereby squeezing the object to be measured. The object to be measured is centered through multiple limit blocks 16 and finally stops at the center position of the placement seat 3. After completion, the slider 8 returns to its original position, thereby making the limit block 16 return to its original position. At this time, the limit block 16 is retracted into the interior of the limit groove 15 to avoid obstruction caused by the limit block 16 when the measuring body 1 is scanned;

[0034] Reference Figure 1-4 , a second gear ring 9 and a second gear 10 are rotatably installed on the top of the base 2, and the second gear 10 is meshed with the second gear ring 9. A first motor 11 is fixedly installed inside the base 2, and the output end of the first motor 11 is fixedly connected to the bottom of the second gear 10. By setting the first motor 11 and starting the first motor 11, the second gear 10 is driven to rotate, and the second gear ring 9 is rotated through the meshing connection between the second gear 10 and the second gear ring 9, and the first gear 6 is rotated through the meshing connection between the second gear ring 9 and the first gear 6;

[0035] Reference Figure 1-4 A rotating plate 12 is rotatably installed inside the base 2, and an arc-shaped groove 13 is provided on the top of the rotating plate 12. A sliding shaft 14 is provided inside the sliding sleeve of the arc-shaped groove 13. The top of the sliding shaft 14 is fixedly connected to the bottom of the slider 8. A second motor 19 is fixedly installed inside the base 2, and the output end of the second motor 19 is fixedly connected to the bottom of the rotating plate 12. By setting the rotating plate 12, the second motor 19 is started to drive the rotating plate 12 to rotate. Since an arc-shaped groove 13 is provided on the surface of the rotating plate 12, and the shape of the arc-shaped groove 13 is set to an inclined straight groove shape, the inner wall of the arc-shaped groove 13 squeezes the sliding shaft 14. Since the center of the rotating plate 12 coincides with the center of the placement seat 3, the sliding shaft 14 drives the slider 8 to move in the direction close to the central axis of the placement seat 3.

[0036] Specifically, the working process or working principle of this scanning measuring instrument is as follows: when in use, the object to be measured is placed on the top of the placement seat 3, and the second motor 19 is started to drive the rotating plate 12 to rotate. Since the surface of the rotating plate 12 is provided with an arc groove 13, and the shape of the arc groove 13 is set to an inclined straight groove shape, the inner wall of the arc groove 13 causes compression on the sliding shaft 14. Since the center of the rotating plate 12 coincides with the center of the placement seat 3, the sliding shaft 14 drives the slider 8 to move in the direction close to the central axis of the placement seat 3, and the movement of the slider 8 drives the limit block 16 to move inside the limit groove 15. Since part of the shape of the change direction groove is set to an inclined type, the change direction groove inner wall squeezes the change direction shaft, so that the change direction shaft drives the limit block 16 to move close to the central axis of the placement seat 3. At the same time, the limit block 16 also moves upward, so that the top of the limit block 16 penetrates the top of the placement seat 3 and continues to extend upward, thereby The object to be measured is squeezed, and the object to be measured is centered through multiple limit blocks 16, and finally stops at the center position of the placement seat 3. After completion, the second motor 19 is started in reverse to return the slider 8 to its original position, thereby returning the limit block 16 to its original position. At this time, the limit block 16 is retracted into the inside of the limit groove 15 to avoid obstruction caused by the limit block 16 when the measuring body 1 is scanning. The first motor 11 is started to drive the second gear 10 to rotate, and the second gear ring 9 is engaged with the second gear 10, so that the second gear ring 9 rotates. The meshing connection between the second gear ring 9 and the first gear 6 makes the first gear 6 rotate. Due to the meshing connection between the first gear 6 and the first gear ring 5, the first gear ring 5 rotates, so that the rotating rod 4 drives the measuring body 1 to rotate. Since the center of the first gear ring 5 coincides with the center of the placement seat 3, the measuring body 1 rotates around the object to be measured and performs scanning measurement at the same time.
