Description

Technical Field

[0001] The present invention relates to the technical field of architectural design, and in particular to a three-dimensional model platform dedicated to architectural engineering design. Background Art

[0002] An architectural model is a sample made of easily processed materials in accordance with architectural design drawings or design concepts and at a reduced scale. An architectural model is a means of expressing the appearance and spatial relationship of a building or a complex of buildings in architectural design. The process of making an architectural model generally includes cutting, grinding, carving, and assembly. The architectural model plate needs to be ground to facilitate the subsequent production of the architectural model.

[0003] In the process of grinding and processing, existing building models use laser grinding to remove burrs and make holes on the models, and the three-dimensional mobile platform can greatly improve the processing efficiency and accuracy of the models. For example, the utility model with the announcement number CN220943692U specifically discloses a three-dimensional model platform dedicated to architectural engineering design. The building model can be clamped and transported by the provided clamping mechanism, and the lifting platform can raise the height of the building model and drive it to rotate and adjust the orientation to ensure the processing efficiency. In addition, the clamping and rotation of the clamping mechanism can turn the building model over so as to perform laser processing on the blind corner of the reverse side.

[0004] In the actual production process, if you want to remove burrs with large areas and regular shapes, ordinary focusing laser heads can meet the needs. By adjusting the power and scanning speed of the laser, the burrs can be removed quickly. However, for burrs in some complex shapes and narrow spaces, such as corners inside the model and edges of holes, it is necessary to use a galvanometer laser head or a fiber-coupled laser head with a smaller spot size and higher energy concentration. They can reach these locations more flexibly and accurately remove burrs without affecting the surrounding materials. However, the three-dimensional model platform disclosed in the prior art requires manual replacement of the laser head during specific use, which affects the processing efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 10 , the present invention provides a technical solution:

[0043] A three-dimensional model platform for architectural engineering design, comprising a base 1 and a box body 2 connected to the upper end surface of the base 1 by screws, a cabinet door 3 is hingedly connected to the front end surface of the base 1 and the box body 2, a processing platform 12 is fixed by screws to the upper end surface of the base 1, two sides of the processing platform 12 are movably connected to vertical frames 4, a fixed column 5 is movably connected between the two vertical frames 4, three laser heads 52 are equidistantly distributed in an annular shape outside the fixed column 5, and the laser head 52 is movably connected to the fixed column 5;

[0044] A rotating disk 13 for placing the building model to be processed is rotatably connected to the middle of the upper end surface of the processing platform 12, and a fixture for fixing the building model to be processed is symmetrically arranged on the rotating disk 13;

[0045] The side of the left stand 4 is movably connected with a motor 21, and the output shaft of the motor 21 is drivingly connected with the fixed column 5;

[0046] A collecting chamber 16 is provided inside the base 1 and the processing platform 12, and a rotating disk 13 is rotatably connected to the top opening of the collecting chamber 16. Air holes are provided through the surface of the rotating disk 13, and an installation chamber 14 is provided at the lower side of the collecting chamber 16. A motor 15 is fixed in the installation chamber 14, and a transmission rod 17 is fixedly connected to the output shaft of the motor 15. The transmission rod 17 extends into the collecting chamber 16 and is fixed to the center position of the lower end surface of the rotating disk 13. A connector 11 is fixed to one side of the base 1, and the connector 11 is connected to the inside of the collecting chamber 16 through an air passage.

[0047] During the processing of the building model to be processed, since the surface of the rotating disk 13 is provided with air holes, in the subsequent processing process, the connector 11 is connected to the external negative pressure equipment pipeline, and the dust or toxic and harmful gases generated during the processing can be sucked into the collection chamber 16 through the air holes, and then flow to the connector 11 through the airway to be pumped to the designated processing equipment.

[0048] Specifically, Figure 1 and Figure 2As shown, guide grooves are provided on both sides of the processing platform 12, and guide blocks are slidably connected in the guide grooves. The guide blocks are fixed to the stand 4, and an electric push rod 22 is fixed to the rear end surface of the box body 2 at a position corresponding to the guide groove, and the output shaft of the electric push rod 22 extends into the guide groove and is fixed to the guide block.

[0049] By adopting the above technical solution, when working, the building model to be processed is placed on the upper end surface of the rotating disk 13 and the bottom edge of the building model is clamped and fixed by a clamp, and then the fixed column 5 is driven to rotate by the motor 21, and one of the different types of laser heads 52 located on the fixed column 5 is adjusted so that the laser emitting end of the laser head 52 is downward. The live parts of the present application are all connected to the external intelligent controller, and can be automatically controlled by the controller. Then the controller controls the motor 15 to drive the transmission rod 17 to drive the rotating disk 13 to rotate on the surface of the processing platform 12, and drive the building model to be processed to rotate. The controller synchronously controls the electric push rod 22 to drive the guide block located in the guide groove to move forward and backward in the guide groove to adjust the position of the stand 4 above the processing platform 12, and adjust the position of the laser head 52 to realize the processing of different positions of the building model to be processed below.

[0050] Specifically, Figure 4 and Figure 7 , Fig.10 As shown, the clamp includes a slide groove 132 symmetrically opened on the rotating disk 13 , and a slider 134 is slidably connected in the slide groove 132 , a clamping plate 131 is fixed on the top of the slider 134 , and a spring 133 is fixed between the slider 134 and the slide groove 132 .

[0051] By adopting the above technical solution, when the architectural model to be processed is placed on the surface of the rotating disk 13, the user pushes the clamping plate 131 to both sides respectively, and the slider 134 at the bottom of the clamping plate 131 slides and connects in the slide groove 132 to stably displace. When the slider 134 displaces in the slide groove 132, the spring 133 is compressed. The elastic force of the spring 133 reversely drives the slider 134 and the clamping plate 131 to clamp and fix the bottom edge of the architectural model to be processed, so as to realize the combination and fixation of the architectural model to be processed and the rotating disk 13. The architectural model to be processed is directly removed after subsequent processing is completed, and the clamping plate 131 is automatically reset under the force of the spring 133. The clamping plate 131 and the slider 134 are fixed by screws, so that different clamping plates 131 can be replaced according to the type of the architectural model to be processed, such as arc shape, irregular shape, etc.

[0052] Specifically, Figure 2 , Figure 5 and Figure 8As shown, a displacement groove 41 is vertically penetrated inside the stand 4, a displacement block 43 is slidably connected in the displacement groove 41, both ends of the connecting shaft 64 extend into the displacement block 43 and are rotatably connected with the displacement block 43, a bar-shaped electromagnet 44 is embedded in the inner wall of the displacement groove 41, the displacement block 43 is made of a magnetic metal material, the displacement block 43 and the displacement groove 41 are in a cross-shaped structure and cooperate with each other, a track 42 is embedded in the outer side of the left stand 4, the motor 21 is slidably connected to the stand 4 through the track 42, and a fixed column 5 is penetrated in the center. The rotating groove 56 has a connecting shaft 64 rotatably connected therein, and an electromagnet ring 2 66 is embedded at both ends of the rotating groove 56. Both ends of the connecting shaft 64 extend to the rotating groove 56. The connecting shaft 64 is made of a magnetic metal material. A gear 6 is sleeved on the outside of the connecting shaft 64 between the left side frame 4 and the fixed column 5. An electromagnet ring 65 is embedded inside the gear 6. A rack 61 is fixed to the left side frame 4 at the rear side of the gear 6. The rack 61 is meshed with the gear 6 and is made of a strong magnetic material.

[0053] By adopting the above technical solution, in the actual processing process, it is necessary to further adjust the distance between the laser head 52 and the bottom of the building model to be processed, so it is necessary to adjust the height of the laser head 52 on the stand 4. At this time, the controller controls the electromagnet ring 165 built in the gear 16 to conduct electricity to generate magnetic force, so that the gear 16 and the connecting shaft 64 are magnetically fixed, and then the bar electromagnet 44 is controlled to cut off the electromagnetic force, and then the motor 21 drives the connecting shaft 64 to rotate clockwise, driving the gear 16 to rotate. At this time, the gear 16 will make the gear 16 mesh with the rack 61. The gear 1-6 rolls downward on the surface of the rack 61, thereby driving the displacement block 43 to move downward inside the displacement slot 41, and the motor 21 can further move downward on the surface of the left stand 4 through the track 42 to prevent the motor 21 from rotating. Then, during the rolling downward displacement of the gear 1-6, the height of the fixed column 5 between the two stands 4 is further adjusted through the connecting shaft 64, thereby realizing the adjustment of the height of the laser head 52 on the fixed column 5. After the adjustment is completed, the electromagnet ring 1-65 is powered off, and the bar electromagnet 44 conducts electricity to generate magnetic force, which magnetically fixes the displacement block 43 in the displacement slot 41.

[0054] Specifically, Figure 2 , Figure 6 , Figure 8 and Fig. 9As shown, three groups of movable grooves 51 are equidistantly provided in an outer ring shape of the fixed column 5, and a threaded rod 55 is rotatably connected inside the movable groove 51, the outer thread of the threaded rod 55 is threadedly connected to a movable block 54, the outer part of the movable block 54 is fixedly connected to a fixed seat 53, and a laser head 52 is connected to the fixed seat 53. Three groups of gears 2 62 are provided between the right side frame 4 and the fixed column 5, and the three groups of gears 2 62 correspond to the threaded rod 55, and the gear 2 62 is fixed to one end of the threaded rod 55, and a gear 3 63 is meshingly connected between the three gears 2 62, the gear 3 63 is sleeved on the outside of the transmission connecting shaft 64, and the inner part of the gear 3 63 is embedded with an electromagnet ring 3 67.

[0055] By adopting the above technical solution, in the actual processing process, it is also necessary to displace the laser head 52 on the fixed column 5 horizontally to the left and right to adjust the position of the laser head 52. Before that, when adjusting one of the laser heads 52, the connecting shaft 64 is driven to rotate by the motor 21, and the controller controls the electromagnet ring 2 66 in the rotating groove 56 to conduct electricity to generate magnetic force, so as to magnetically fix the connecting shaft 64 and the fixed column 5, and then the motor 21 can be controlled to rotate to drive the fixed column 5 to rotate, so as to adjust the angles of different types of laser heads 52 at different positions on the surface of the fixed column 5. In subsequent processing, when it is necessary to control the laser head 52 to be used to be displaced horizontally on the surface of the fixed column 5, it is necessary to control the electromagnet ring 2 66 to be powered off, and then control the electromagnet ring 3 67 to conduct electricity. Electricity generates magnetic force, which magnetically fixes the connecting shaft 64 and the gear three 63, thereby driving the gear three 63 to rotate. At this time, the gear two 62 meshing with the gear three 63 rotates, thereby driving the threaded rod 55 to rotate. When the threaded rod 55 located in the movable groove 51 rotates, it is also slidably connected in the movable groove 51, and the movable block 54 threadedly connected to the threaded rod 55 is displaced in the movable groove 51, thereby driving the fixed seat 53 fixed with the movable block 54 to be displaced, and the position of the laser head 52 on the fixed seat 53 is adjusted. This structure drives and adjusts the three threaded rods 55 at the same time. In the subsequent use process, the threaded rod 55 and the gear two 62 can also be connected by rotation in combination with an electromagnet to achieve independent control of the rotation of a single threaded rod 55.

[0056] Working principle: during operation, the building model to be processed is placed on the upper end surface of the rotating disk 13 and the bottom edge of the building model is clamped and fixed by a clamp, and then the fixed column 5 is driven to rotate by the motor 21, and one of the different types of laser heads 52 located on the fixed column 5 is adjusted so that the laser emitting end of the laser head 52 is facing downward. The live parts of the present application are all connected to the external intelligent controller, and can be automatically controlled by the controller. Then the controller controls the motor 15 to drive the transmission rod 17 to drive the rotating disk 13 to rotate on the surface of the processing platform 12, and drive the building model to be processed to rotate. The controller synchronously controls the electric push rod 22 to drive the guide block located in the guide groove to move forward and backward in the guide groove to adjust the position of the stand 4 above the processing platform 12, and adjust the position of the laser head 52 to realize the processing of different positions of the building model to be processed below;

[0057] When the architectural model to be processed is placed on the surface of the rotating disk 13, the user pushes the clamping plate 131 to both sides respectively, and the slider 134 at the bottom of the clamping plate 131 slides in the slide groove 132 to stably displace. When the slider 134 displaces in the slide groove 132, the spring 133 is compressed. The elastic force of the spring 133 reversely drives the slider 134 and the clamping plate 131 to clamp and fix the bottom edge of the architectural model to be processed, so as to realize the combination and fixation of the architectural model to be processed and the rotating disk 13. After the subsequent processing is completed, the architectural model to be processed is directly removed, and the clamping plate 131 is automatically reset under the force of the spring 133. The clamping plate 131 and the slider 134 are connected and fixed by screws, so that different clamping plates 131 can be replaced according to the type of the architectural model to be processed, such as arc shape, irregular shape, etc.

[0058] In the actual processing process, it is necessary to further adjust the distance between the laser head 52 and the bottom of the building model to be processed, so it is necessary to adjust the height of the laser head 52 on the stand 4. At this time, the controller controls the electromagnet ring 165 built in the gear 16 to conduct electricity to generate magnetic force, so that the gear 16 and the connecting shaft 64 are magnetically fixed, and then the bar electromagnet 44 is controlled to cut off the electromagnetic force, and then the motor 21 drives the connecting shaft 64 to rotate clockwise, driving the gear 16 to rotate. At this time, the gear 16 is meshed with the rack 61, which makes the gear 16 move downward on the surface of the rack 61. Rolling displacement, thereby driving the displacement block 43 to move downward inside the displacement slot 41, and the motor 21 can further move downward on the surface of the left stand 4 through the track 42 to prevent the motor 21 from self-rotating, and then the gear 1 6 further adjusts the height of the fixed column 5 between the two stands 4 through the connecting shaft 64 during the rolling displacement downward, thereby realizing the adjustment of the height of the laser head 52 on the fixed column 5. After the adjustment is completed, the electromagnet ring 1 65 is powered off, and the bar electromagnet 44 conducts electricity to generate magnetic force, which magnetically fixes the displacement block 43 in the displacement slot 41;

[0059] In the actual processing process, it is also necessary to displace the laser head 52 on the fixed column 5 horizontally to the left and right to adjust the position of the laser head 52. Before that, when adjusting one of the laser heads 52, the connecting shaft 64 is driven to rotate by the motor 21, and the controller controls the electromagnet ring 2 66 in the rotating groove 56 to conduct electricity to generate magnetic force, so as to magnetically fix the connecting shaft 64 and the fixed column 5, and then the fixed column 5 can be driven to rotate by controlling the rotation of the motor 21 to adjust the angle of different types of laser heads 52 at different positions on the surface of the fixed column 5. In subsequent processing, when it is necessary to control the lateral displacement of the laser head 52 to be used on the surface of the fixed column 5, it is necessary to control the electromagnet ring 2 66 to be powered off, and then control the electromagnet ring 3 67 to conduct electricity to generate magnetic force, so as to magnetically fix the connecting shaft 64 and the gear 3 63, and then drive the gear 3 63 to rotate. The gear two 62 meshed with the wheel three 63 rotates, thereby driving the threaded rod 55 to rotate. When the threaded rod 55 located in the movable groove 51 rotates, it is also slidably connected in the movable groove 51, and the movable block 54 threadedly connected to the threaded rod 55 is displaced in the movable groove 51, thereby driving the fixed seat 53 fixed to the movable block 54 to be displaced, and the position of the laser head 52 on the fixed seat 53 is adjusted. This structure drives and adjusts the three threaded rods 55 at the same time. In the subsequent use process, the threaded rod 55 and the gear two 62 can also be connected by rotation in conjunction with an electromagnet to achieve independent control of the rotation of a single threaded rod 55. In order to avoid the connection shaft 64 from rotating during the process of driving the threaded rod 55 to rotate, thereby driving the fixed column 5 to rotate, the rack 61 is made of strong magnetic material, and one side of the rack 61 is magnetically fixed to the end face of the fixed column 5.
