Description
Technical Field
[0001] This disclosure relates to the field of testing equipment technology, and in particular to a three-dimensional measuring device and a three-dimensional measuring system.
[0002] Background Technology Most 3D measuring devices have an integrated frame structure, suitable for large-scale tracking scanning scenarios. However, in special scenarios requiring the simultaneous measurement of large shapes and small cavities, their bulky size when operating alone without a tracker makes them inconvenient to use in confined spaces. Furthermore, traditional tracking-type 3D measuring devices, when used in small-scale conditions, require not only separate calibration of the 3D measuring device but also calibration of the positional relationship between the tracker and the 3D measuring device, a complex process. Existing tracking-type 3D measuring devices are complex to connect and assemble, difficult or impossible to disassemble independently, limiting their application scenarios and making calibration cumbersome. Summary of the Invention
[0003] This disclosure aims to address at least one of the technical problems existing in the prior art or related technologies.

Detailed Implementation
[0020] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

In the description of the embodiments of this disclosure, "a plurality of" means two or more, unless otherwise explicitly defined.
[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this disclosure. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0025] Currently, users are increasingly demanding higher application ranges and better user experience from tracking-type 3D measurement equipment, with a particular emphasis on multi-application scenarios. For example, the tracking scanner described in CN222938454U has an integrated frame that is difficult to disassemble and use separately; another example is the tracking scanner described in CN222258118U, which uses a regular polyhedral structure for support, has a complex connection structure, and cannot be disassembled for use as a handheld scanner.
[0026] Based on this, this disclosure provides a three-dimensional measuring device. The locking mechanism, through mechanical engagement, enables one-click fixing and releasing of the device body, eliminating the need for complex tools, significantly reducing operation time and improving efficiency. Furthermore, the mating design of the base and pedestal ensures the stability of the three-dimensional measuring device body during scanning, preventing shaking or displacement and improving data acquisition accuracy. The locking mechanism secures the pedestal to the position on the base, allowing the user to adjust the position between them as needed, thereby adjusting the scanning angle of the three-dimensional measuring device body to adapt to objects of different sizes or complex scanning scenarios, enhancing the device's versatility and adaptability.
[0027] The three-dimensional measuring device will be described in detail below through specific embodiments: Reference Figures 1 to 22As shown, a first aspect of this disclosure provides a three-dimensional measuring device, including a frame 1, a three-dimensional measuring device body 2, and a locking mechanism 3. The frame 1 has a device mounting position 11, and the three-dimensional measuring device body 2 is detachably connected to the device mounting position 11 via the locking mechanism 3. The locking mechanism 3 includes a base 31, a base 32, and a locking element 33. The base 31 is connected to the device mounting position 11, the base 32 is connected to the three-dimensional measuring device body 2, and the locking element 33 is used to fix the position of the base 32 on the base 31.
[0028] In this embodiment, the locking mechanism includes a base 31, a base 32 connecting the 3D measuring device body 2, and a locking element 33 fixing their positions. The locking element 33 achieves one-click fixing and releasing of the 3D measuring device body 2 through mechanical engagement, such as clamping or snap-fitting, eliminating the need for complex tools, significantly reducing operation time, and improving efficiency. Furthermore, the cooperative design of the base 31 and base 32 ensures the 3D measuring device body 2 remains stable during scanning, preventing shaking or displacement and improving data acquisition accuracy. The detachable design of the 3D measuring device body 2 simplifies cleaning, replacement, or upgrade processes, reduces maintenance costs, and extends the device's lifespan. It should be noted that the locking element 33 can be a separate component or integrated with the base 31 or base 32; that is, the locking element 33 is integrated with the base 31 and base 32. Specifically, this embodiment sets the locking element 33 as a separate component.
[0029] Specifically, the three-dimensional measuring device body 2 of this disclosure can be a combination of a scanner, a light pen, or a pattern projector, or one or more of these mechanisms, and is not limited to a specific model. The frame 1 of this disclosure is configured as an integrated ball cage frame, which consists of 11 ball plate structures and a handle assembly. The base 31 of this disclosure can be embedded within the integrated ball cage frame to achieve structural stability. Specifically, this can be achieved by providing grooves on opposite sides of the base 31, and providing sliders on the frame 1 that fit these grooves, allowing for a sliding connection. When the base 31 is in the appropriate position, it can be fixed using bolts.
[0030] In some embodiments, the base 32 is provided with a groove 321, and the locking member 33 includes a body 331 and a locking part 332. The locking part 332 is connected to the body 331, and the body 331 is connected to the base 31. The body 331 is used to drive the locking part 332 closer to or away from the side of the base 31 facing the base 32. In the fixed state of the locking member 33, the body 331 passes through the groove 321, and the locking part 332 at least partially abuts against the base 32.
[0031] In this embodiment, the main body 331 drives the locking part 332 to move by rotation, which can realize the self-locking of the position of the locking part 332, so as to quickly fix the relative position of the base 32 and the base 31 without the need for other auxiliary tools to fix it, thereby improving the position fixing accuracy of the base 32 and the base 31, and also facilitating quick assembly and disassembly.
[0032] Specifically, the main body 331 of this disclosure has a handle or knob on the side away from the base 31 to facilitate its rotation. When the main body 331 is inserted into the base 31, the locking part 332 moves away from the base 31, specifically in the vertical direction of the base 31. When the main body 331 is rotated out of the base 31, the locking part 332 moves towards the base 31, thereby fixing the base 32 and the base 31. The locking part 332 of this disclosure can be a pressure plate, such as a circular pressure plate, a rectangular pressure plate, etc., and this disclosure specifically uses a circular pressure plate. Regarding the cooperation between the locking part 332 and the main body 331, the locking part 332 can be a pressure plate with a diameter larger than that of the main body 331, and the diameter of the main body 331 is adapted to the diameter of the slide groove 321. In use, the main body 331 passes through the slide groove 321. After the position of the base plate 32 and the base 31 is adjusted, the main body 331 is rotated outward from the base 31. At this time, because the diameter of the locking part 332 is greater than the diameter of the main body 331, that is, greater than the diameter of the slide groove 321, the locking part 332 presses the base 32 and the base 31 together and fixes them under the continuous downward driving of the main body 331.
[0033] It is understandable that a certain gap needs to be left in the assembly of the three-dimensional measuring device body 2 and the base 32 so that the locking part 332 can be located between the three-dimensional measuring device body 2 and the base 32. The locking part 332 is driven by the body 331 towards the base 31 so that the base 32 and the base 31 are pressed together.
[0034] In some embodiments, the locking part 332 and the body 331 of this disclosure are configured to be detachably connected. Specifically, a screw connection can be used, for example, a threaded hole is provided at the center of the end of the body 331, and the locking part 332 is provided with a threaded post that matches the threaded hole on the body 331 for screw connection.
[0035] In some embodiments, the locking portion 332 and the body 331 of this disclosure are integrally formed, and the diameters of the locking portion 332 and the body 331 are the same. The transition portion between the two is configured as a necked structure, such as... Figure 5 , 7 As shown in Figure 9, the main body 331 and the locking part 332 have an I-shaped structure, and the sliding groove on the base 32 is set as follows: Figure 4 , 8The notch groove shown in Figure 10 has a width that matches the diameter of the necking structure. In use, the body 331 is screwed into the base 31, causing the locking part 332 to move away from the base 31. At this time, the necking structure is partially or completely exposed on the plate surface of the base 331. Then, the necking mechanism is slid into the notch groove from the side of the base 32. After fixing the position of the base plate 32 on the base plate 31, the body 331 is screwed out to the outside of the base 31, causing the locking part 332 to move towards the base 31, pressing the base 32 and the base 31 together, thus fixing their relative positions.
[0036] In some embodiments, the locking member 33 further includes a rotating sleeve 333 and a connecting plate 334. The base 31 has a through hole in the direction toward the device mounting position 11. The rotating sleeve 333 is detachably inserted into the through hole through the connecting plate 334. The body 331 is connected to the rotating sleeve 333.
[0037] In this embodiment, the rotating sleeve 333 is quickly and detachably connected to the base 31 via the connecting plate 334. The detachable connection design facilitates the individual replacement of damaged rotating sleeve components, reducing maintenance costs and shortening the replacement time of the three-dimensional measuring equipment body 2. The connecting plate 334, as an intermediate force transmission component, evenly transmits the force of the rotating sleeve 333 to the base 31, which improves vibration resistance compared to the direct fixing method.
[0038] Specifically, the rotating sleeve 333 of this disclosure is a cylindrical sleeve with open ends. The rotating sleeve 333 and the base 31 are fitted together by a damped fit, a clearance fit, or an interference fit. Damped fits and interference fits can better fix the rotating sleeve 333. It is understood that in the interference fit embodiment, the rotating sleeve 333 and the base 31 are not easily fixed too tightly to prevent the rotating sleeve 333 from being unable to be removed or difficult to assemble. This disclosure specifically uses a clearance fit to facilitate the installation and disassembly of the rotating sleeve 333, and uses a connecting plate 334 to achieve the stability of the rotating sleeve 333. The connecting plate 334 can be a flange plate or a plate-shaped metal. The connection between the connecting plate 334 and the base 31 can be a snap-fit connection or a bolt connection. This disclosure specifically uses a bolt connection to improve the stability of the rotating sleeve 333.
[0039] In some embodiments, the locking member 33 further includes a rotating sleeve 333, which has a spirally rising strip hole 3331 in the circumferential direction, and a detachably connected cylindrical pin 3332 is provided on the side wall of the body 331, which is slidably connected to the strip hole 3331.
[0040] In this embodiment, the rotational motion can be converted into linear displacement through the engagement of the spirally ascending slot 3331 and the cylindrical pin 3332, achieving higher positioning accuracy. The axial force generated by the spiral structure enables the locking component to have a self-locking function, maintaining a stable connection even under vibration. Furthermore, the detachable connection design between the cylindrical pin 3332 and the slot 3331, combined with the spiral guide, significantly shortens the replacement time of the three-dimensional measuring equipment body 2, improving replacement efficiency. Moreover, the spiral slot 3331 of the rotating sleeve 333 evenly transmits torque to the body 331, resulting in a more reasonable stress distribution.
[0041] Specifically, in this embodiment, the slotted hole 3331 has a certain self-locking effect, for example, the slotted hole 3331 can be configured as a cam groove structure. Further, the body 331 of this disclosure can be threadedly connected to the rotating sleeve 333, and the slotted hole 3331, in conjunction with the cylindrical pin 3332, aims to limit the rotational stroke of the body 331. In another embodiment, the body 331 may not be threaded to the rotating sleeve 333, such as... Figure 13 As shown, the strip-shaped hole 3331 is designed as a cam groove. The cam groove dynamically engages with the needle roller bearing on the indexing plate through its specific contour curve, forming a rigid self-locking mechanism during specific phases of the motion cycle. This ensures the precise position of the indexing plate when it is stationary. In other words, the position positioning of the body 31 is achieved solely through the self-locking capability of the strip-shaped hole 3331. Furthermore, to improve the stability of positioning, the position of the body 331 on the rotating sleeve 333 can be fixed by using external clamps, buckles, locking blocks, set screws, etc.
[0042] In some embodiments, the stroke of the cylindrical pin 3332 between the top dead center and the bottom dead center of the slot 3331 is set to a quarter rotation of the body 331 in the circumferential direction.
[0043] In this embodiment, by precisely corresponding the stroke of the cylindrical pin 3332 in the slot 3331 to the rotation angle of the body 331 (1 / 4 turn of rotation corresponds to the full stroke), the positioning accuracy can be improved. When the body 331 rotates to the end of the stroke, the axial force generated by the helical structure can also form a self-locking mechanism, maintaining a stable connection. The fixed correspondence between stroke and angle (1 / 4 turn of rotation = full stroke) ensures repeatability and meets the requirements for high-precision positioning. It should be noted that the slot 3331 in this disclosure is a helical ascending structure, so the end point of the slot 3331 near the locking part 332 is the upper dead point, and the end point away from the locking part 332 is the lower dead point.
[0044] In some embodiments, the locking member 33 includes a guide post 335, a guide sleeve 336, a locking part 332, and a driving part 337. The guide sleeve 336 passes through the base 31, the guide post 335 passes through the guide sleeve 336, the locking part 332 is connected to the guide post 335, and the locking part 332 is used to clamp the base 32 to the base 31. The driving part 337 is used to apply the clamping force of the locking part 332.
[0045] In this embodiment, the precise fit between the guide post 335 and the guide sleeve 336 improves axial positioning accuracy, ensures that the clamping force of the locking part 332 is transmitted along the designed path, and avoids stress concentration caused by off-center loading. This embodiment is the second implementation of the locking member 33 of this disclosure. The clamping force of the locking part 332 is directly applied by the driving part 337 to fix the relative position of the base 32 and the base 31, so as to better achieve quick assembly and disassembly.
[0046] In some embodiments, the guide post 335 includes a first post 3351, a second post 3352, and an elastic member 3353. One end of the first post 3351 is connected to the drive unit 337, and the other end is connected to the second post 3352 via the elastic member 3353. A locking part 332 is connected to the second post 3352. The drive unit 337 includes a wrench 3371 and a cam structure 3372. The cam structure 3372 is disposed at the end of the wrench 3371. Hinged to the first column 3351, the wrench 3371 is used to drive the cam structure 3372 to rotate; in the fixed state of the locking member 33, the high point of the cam structure 3372 contacts the guide sleeve 336 and / or the base 31, and the locking part 332 clamps the base 32 to the base 31; in the unlocked state of the locking member 33, the low point of the cam structure 3372 contacts the guide sleeve 336 and / or the base 31, and the locking part 332 moves away from the base 32 through the elastic member 3353.
[0047] In this embodiment, the elastic element 3353 can be specifically set as a spring or a rubber elastic pad; this disclosure specifically uses a spring. The hard contact between the high point of the cam and the guide sleeve 336 and / or the base 31 forms a rigid stop to improve pull-out resistance. The 90-degree rotation of the wrench 3371 significantly shortens the unlocking / locking switching time, improving assembly efficiency. The low point of the cam provides clearance, causing the guide post 335 to be pulled back. At this time, the travel space of the guide post 335 increases, the spring is released, and the second post 3352 is lifted back to the unlocked state, creating a gap between the locking part 332 and the base plate 32, allowing the base plate 32 to be disassembled. When the high point of the cam contacts the guide sleeve 336 and / or the base 31, the travel space of the guide post 335 becomes shorter, the spring is compressed, and the second post 3352 is pulled back, thereby clamping and fixing the base plate 32 and the base 31 together. This disclosure precisely controls the follower stroke through a cam profile curve (such as a disc cam or a cylindrical cam), converting the rotational motion of the wrench 3371 into the linear clamping force of the locking part 332, which greatly improves the transmission efficiency and allows for flexible design of the motion law.
[0048] Specifically, the hinge between the cam structure 3372 and the first column 3351 is achieved through a combined shaft. When the wrench 3371 drives the cam structure 3372 to rotate, the cam structure 3372 drives the first column 3351 to extend and retract through the cam characteristics. The elastic element 3353 is designed to provide the cam structure 3372 so that the travel space of the guide column 335 is lengthened, thereby lifting and resetting the second column 3352.
[0049] In some embodiments, the base 31 is provided with a base mounting position 100 on the side facing the device mounting position 11, and guide plates 101 are provided on opposite sides of the base mounting position 100. The guide plates 101 are used to guide the base 32 to be mounted in the base mounting position 100.
[0050] In some embodiments, such as Figures 19 to 21 As shown, the base 31 and base 32 of this disclosure are connected by quick-release bolts 32, allowing for quick assembly and disassembly without tools. This is suitable for scenarios requiring frequent adjustments. The spring or cam structure of the quick-release bolts 200 provides continuous pressure, effectively resisting loosening of the connection caused by micro-vibrations resulting from the movement and angle adjustment of the 3D measuring device body 2 during scanning. Specifically, two quick-release bolts 200 are provided on the base 31, spaced apart, and the corresponding base 32 has quick-release bolt holes.
[0051] In this embodiment, the symmetrical arrangement of the guide plates 101 improves the positioning accuracy of the base 32, and the distance between the two guide plates 101 is the width of the base 32. The open design of the guide plates 101 allows the base 32 to slide in quickly along a preset path, thus shortening the assembly time. Simultaneously, this structure supports tool-free assembly and disassembly, facilitating periodic calibration or component replacement. Furthermore, the spacing of the guide plates 101 can be adjusted according to different specifications of the base 32. Specifically, the guide plates 101 are detachably connected to the bearing surface of the base 31 by bolts, and multiple bolt holes with different spacings are provided on the bearing surface of the base 31 to precisely adjust the spacing between the two guide plates 101. Further, one side of the two guide plates 101 facing each other can be set as an arc surface or a slope, and the two sides of the corresponding base 32 are also set as arc surfaces or shoe uppers. For example, the guide plates 101 are set as inner arcs, and the edges of the base 32 are set as outer arc surfaces, so that the two can achieve better positioning during assembly.
[0052] In some embodiments, the base mounting position 100 is provided with a positioning magnetic member 102, which is used to magnetically attract the base 32.
[0053] In this embodiment, the positioning magnetic chuck 102 can be configured as a magnet, electromagnet, etc., and specifically, a magnet is selected in this disclosure. This disclosure achieves automatic alignment of the base 32 through magnetic attraction, thereby improving assembly efficiency and positioning accuracy. The symmetrical design of the magnetic poles can eliminate the rotational degree of freedom of the base 32 and avoid frictional losses of traditional mechanical guides. Specifically, the number of positioning magnetic chucks 102 can be set to four, with the four magnetic chucks evenly distributed along the circumference of the body 331. In this embodiment, the body 331 can be inserted through the center point of the base 31 or other areas selected according to the model of the three-dimensional measuring equipment. Specifically, this disclosure inserts the body 331 through the center point of the base 31 to facilitate the symmetrical arrangement and coordination of the components. It is understood that the base 32 of this disclosure can be configured as a metal material that can be magnetically attracted, or a metal part or magnetic chuck that can be magnetically attracted by the positioning magnetic chuck 102 can be provided on the base 32.
