Abstract
Description
Technical Field
[0001] This utility model relates to the field of 3D scanning technology for cultural relics, specifically to a tooling for 3D scanning of cultural relics with marking points. Background Technology
[0002] In 3D scanning of cultural relics, marker points are the key reference for scanners to identify spatial coordinates. Traditional marker placement fixtures are usually general-purpose plastic / metal brackets, which are used to manually apply reflective marker points (such as black and white dots or spherical markers). This has the following problems: 1. Low positioning accuracy: Manual placement relies on experience, and the spacing and height of adjacent points are inconsistent, which can easily lead to matching errors during scanning; 2. Risk of damage to cultural relics: Traditional fixtures (such as clamps and straps) may cause pressure or scratches on the surface of fragile cultural relics (such as pottery and lacquerware). Utility Model Content
[0003] The purpose of this invention is to provide a tooling for three-dimensional scanning and marking of cultural relics, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional scanning and marking fixture for cultural relics, comprising a base plate, a bearing seat fixedly mounted on the surface of the base plate, a rotating shaft rotatably mounted on the inner wall of the bearing seat, a platform fixedly mounted on the upper end of the rotating shaft, four sets of limiting plates fixedly mounted on the surface of the platform, each set of limiting plates including two symmetrically mounted limiting plates, a sliding groove penetrating through the inner wall of each of the two symmetrical limiting plates, a slider slidably mounted on the inner wall of each of the two symmetrical sliding grooves, a marking structure fixedly mounted between the two symmetrical sliders, a screw screwed to the outer end of the inner wall of one of the sliders, the screw tightly fitting against the outer wall of the limiting plate on the same side, and a fixing structure fixedly mounted on the lower end of the inner wall of the two symmetrical limiting plates.
[0005] Preferably, the marking structure includes a support cylinder, which is fixedly assembled to the inner end of the slider.

One end of the spring is fixedly connected to the top plate, and the other end of the spring is fixedly connected to the inner wall of the support cylinder. A material bin is fixedly assembled to the inner end of the support cylinder. A pair of reflective marking points are inserted into the inner wall of the material bin. The end of the sliding rod near the material bin passes through the support cylinder and fits against the reflective marking points. An electromagnet is embedded in the inner wall of the end of the sliding rod near the material bin, and a magnet is embedded in the inner wall of the end of the reflective marking point near the sliding rod.

Detailed Implementation
[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figure 1-3This utility model provides a 3D scanning and marking fixture for cultural relics, including a base plate 1. A bearing seat 2 is fixedly mounted on the surface of the base plate 1. A rotating shaft 3 is rotatably mounted on the inner wall of the bearing seat 2. A platform 4 is fixedly mounted on the upper end of the rotating shaft 3. Four sets of limiting plates 5 are fixedly mounted on the surface of the platform 4. Each set of limiting plates 5 includes two symmetrically mounted limiting plates 5. A sliding groove 10 is opened through the inner wall of each of the two symmetrically mounted limiting plates 5. A slider 9 is slidably mounted on the inner wall of each of the two symmetrically mounted sliding grooves 10. A marking structure 6 is fixedly mounted between the two symmetrically mounted sliders 9. A screw 8 is screwed to the outer end of the inner wall of one of the sliders 9. The screw 8 is tightly fitted to the outer wall of the limiting plate 5 on the same side. A fixing structure 7 is fixedly mounted on the lower end of the inner wall of the two symmetrically mounted limiting plates 5.
[0015] The base plate 1 ensures the overall stability of the equipment. The cooperation between the bearing seat 2 and the rotating shaft 3 allows the artifact to be rotated, facilitating the application process and allowing for easy observation of the artifact's surroundings. The artifact is placed on the platform 4 and temporarily fixed by the fixing structure 7 to ensure stability during application. Utilizing the soft and deformable nature of memory foam, the corresponding positions of the fixing supports can vary depending on the artifact, offering strong adaptability and good surface protection. Multiple application structures 6, along with the limiting plate 5, slider 9, and groove 10, allow for effective application of the artifact to multiple locations, ensuring stable, accurate, and effective application with high practicality. The screws 8 can restrict the application structure 6 to a specific longitudinal position, further enhancing the application effect.
[0016] The marking structure 6 includes a support cylinder 61, which is fixedly mounted on the inner end of the slider 9. A slide rod 62 is inserted through the inner wall of the support cylinder 61. A top plate 63 is fixedly mounted on the outer wall of the slide rod 62 and fits tightly inside the support cylinder 61. A spring 66 is sleeved on the outer wall of the slide rod 62. One end of the spring 66 is fixedly connected to the top plate 63, and the other end of the spring 66 is fixedly connected to the inner wall of the support cylinder 61. A material bin 64 is fixedly mounted on the inner end of the support cylinder 61. A pair of reflective marking points 65 are inserted into the inner wall of the material bin 64. The end of the slide rod 62 near the material bin 64 passes through the support cylinder 61 and fits against the reflective marking point 65. An electromagnet is embedded in the inner wall of the end of the slide rod 62 near the material bin 64, and a magnet is embedded in the inner wall of the end of the reflective marking point 65 near the slide rod 62.
[0017] When the application point structure 6 is needed, first adjust the longitudinal position of the support cylinder 61. After adjusting to the appropriate application point position, squeeze the slide rod 62 and push it towards the artifact. This will cause the top plate 63 to compress the spring 66, causing it to deform and store force. At this time, the electromagnet is activated and firmly attracted to the magnetic piece. The slider drives the lowest reflective mark point 65 to extend outward. At this time, remove the patch from the outer end of the reflective mark point to expose the internal adhesive. Continue to push the slide rod 62 to attach the reflective mark point 65 to the outer wall of the artifact. This process is stable and ensures the attachment effect. At this time, turn off the electromagnet and release the slide rod 62. The spring 66 pushes the top plate 63 to move in the opposite direction, retracting the electromagnet end of the slide rod 62 into the support cylinder 61. At this time, the other reflective marks 65 in the material bin 64 fall downward. The lowest of the remaining reflective marks 65 is again attached to the end of the slide rod 62. At this time, turn on the electromagnet to attract the magnetic piece in the reflective mark point 65, preparing for the next application work.
[0018] The fixed structure 7 includes a support block 71, which is fixedly assembled between two limiting plates 5. A screw rod 72 is screwed to the inner wall of the support block 71. The inner end of the screw rod 72 is rotatably assembled with one side wall of a clamping plate 73. The lower end of the clamping plate 73 is in contact with the surface of the shelf 4. Memory foam 74 is fixedly assembled to the other side wall of the clamping plate 73.
[0019] When the artifact is placed on the display platform 4, the screw 72 is rotated. Due to the screw connection between the screw 72 and the support block 71, and the fixed position of the support block 71, the screw 72 will move on the inner wall of the support block 71, and drive the clamp 73 connected to it to move. The clamp 73 will not rotate with the screw 72 because it abuts against the surface of the display platform 4. When the memory foam 74 comes into contact with the artifact, it will deform to the same shape as the contact position, thus supporting and protecting it.
[0020] A throttle is fixedly mounted on the outer end of the screw 72.
[0021] The throttle handle makes it easy to rotate the screw 72.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
