Description

Technical Field

[0001] This invention relates to the field of clamping technology, and more specifically to a rotary model clamping platform. Background Technology

[0002] A model clamping table is a tooling device used to position and fix model workpieces. It can be used in model making, painting, assembly and precision machining. By applying constraints to the model, it keeps it in a stable posture and provides reliable support for subsequent operations.

[0003] Existing model clamping tables mostly use elastic clamping to position and fix the model base, which can meet the needs of conventional clamping. However, when picking up and placing workpieces, operators usually need to manually pry open the clamping parts. The operation process relies heavily on the coordination of both hands, making it difficult to open and close the clamp with one hand. When continuously changing models for painting operations, there is still room for improvement in the ease of operation. Therefore, we propose a rotary model clamping table. Summary of the Invention

[0004] In view of this, the present invention provides a rotary model clamping stage, which aims to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rotary model clamping platform includes a base, a support platform mounted on the upper part of the base, clamping platforms respectively provided at both ends of the support platform, and a clamping station formed between the two sets of clamping platforms. The clamping station is used to place the fixed part, and an elastic component is provided at the end of the support platform, the elastic component being connected to the clamping platform.

[0006] In some embodiments, a central groove is formed in the middle of the support platform, and a vertical fixing column is fixed to the base, the fixing column passing through the central groove; the outer wall of the fixing column is provided with multiple sets of protrusions, the protrusions are placed inside the central groove and abut against the inner wall of the central groove.

[0007] In some embodiments, the top surface of the base is provided with a threaded groove, and the lower end of the fixing column is integrally formed with a threaded column, which is threadedly assembled into the threaded groove.

[0008] In some embodiments, the elastic component includes an assembly groove, a movable block, a spring, a limiting block, and a connecting rod; the assembly groove is opened at the end of the support platform, and the spring and the movable block are arranged sequentially inside the assembly groove. The movable block is slidably disposed along the inside of the assembly groove and is connected to the clamping platform; limiting blocks are fixedly provided on both sides of the movable block inside the assembly groove.

[0009] In some embodiments, one end of the spring abuts against the bottom of the assembly groove, and the other end of the spring abuts against the side wall of the movable block; the assembly groove is provided with a through groove that passes through the central groove and the assembly groove on the side near the clamping table.

[0010] In some embodiments, the connecting rod passes through the through groove, one end of the connecting rod is fixedly connected to the movable block, and the other end of the connecting rod abuts against the fixed column.

[0011] In some embodiments, the support platform can rotate circumferentially about the fixed column.

[0012] In some embodiments, the clamping platform has a stepped shape, and the two clamping platforms are symmetrically arranged at the left and right ends of the support platform; the bottom surface of the fixed member is attached to the top surface of the support platform, and the outer walls on both sides of the fixed member are respectively attached to the inner side walls of the stepped clamping platform.

[0013] In some embodiments, the limiting blocks on both sides respectively abut against the sidewalls of the movable block, the limiting blocks slide in cooperation with the movable block, and the limiting blocks restrict the movable block from laterally disengaging from the assembly groove.

[0014] In some embodiments, the bottom surface of the base is a planar structure.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1-8 This invention provides a rotary model clamping table technical solution: The rotary model clamping table includes a base 1, which is integrally machined into a block-shaped support base. The bottom surface of the base 1 is milled to form a flat plane, which fits perfectly with the worktable when placed. A concave threaded groove 14 is formed downward at the center of the top surface of the base 1, and the inner wall of the threaded groove 14 is machined with internal threads. A vertically arranged fixing post 10 is provided, and the lower end of the fixing post 10 is integrally formed with a threaded post 15. The outer wall of the threaded post 15 is machined with external threads matching the threaded groove 14. During assembly, the threaded post 15 is aligned with the threaded groove 14 and tightened. The fixing post 10 is vertically installed at the center of the top surface of the base 1. The fixing post 10 and the base 1 can be disassembled and assembled.

[0022] The outer wall of the fixed column 10 is integrally formed with multiple sets of circumferentially distributed protrusions 11, which protrude along the outer side of the fixed column 10. A central groove 9, penetrating vertically, is formed in the middle of the support platform 2. The inner diameter of the central groove 9 is larger than the outer diameter of the fixed column 10, and the inner cavity of the central groove 9 can accommodate all the protrusions 11. During assembly, the support platform 2 is fitted onto the fixed column 10 from top to bottom, with the fixed column 10 inserted entirely into the central groove 9. The protrusions 11 are housed within the inner cavity of the central groove 9, and their outer surfaces form a movable contact with the inner wall of the central groove 9. After assembly, the support platform 2 is mounted above the base 1, and can rotate circumferentially around the fixed column 10. The protrusions 11 and the inner wall of the central groove 9 mutually restrain each other, constraining the rotation range of the support platform 2.

[0023] The left and right ends of the support platform 2 are symmetrically recessed to form assembly grooves 5, and the structures of the two assembly grooves 5 are consistent. A through groove 12 is opened on the side wall of each assembly groove 5 near the central groove 9. The through groove 12 horizontally connects the assembly groove 5 and the central groove 9, forming a channel connecting the two cavities. The internal space of the assembly groove 5 is used to place the spring 7, the movable block 6, and the limiting block 8. The length of the groove can meet the stroke required for the horizontal sliding of the movable block 6.

[0024] Along the assembly groove 5 from the bottom towards the through groove 12, first insert the spring 7, with one end of the spring 7 fitting against the inner bottom of the assembly groove 5. Then insert the movable block 6, with the other end of the spring 7 fitting against the side wall of the movable block 6 facing the bottom of the groove. The movable block 6 can slide horizontally back and forth along the inside of the assembly groove 5. Limiting blocks 8 are installed inside the assembly groove 5 and on the left and right sides of the movable block 6, respectively. The inner surfaces of the two limiting blocks 8 fit against the side walls of the movable block 6, forming a sliding fit. The limiting blocks 8 block the lateral displacement of the movable block 6, reducing the possibility of the movable block 6 detaching from the assembly groove 5.

[0025] The connecting rod 13 is passed laterally through the through slot 12, with one end remaining inside the assembly slot 5 and the other end extending into the central slot 9. The end of the connecting rod 13 inside the assembly slot 5 is fixedly connected to the side wall of the movable block 6, and the two move synchronously. The end of the connecting rod 13 extending into the central slot 9 abuts against the outer wall of the fixed column 10. The movable block 6 is fixedly connected to the clamping platform 3 on the same side, and the sliding motion of the movable block 6 can drive the clamping platform 3 to open and close synchronously.

[0026] Clamping platforms 3 are symmetrically installed at both ends of the support platform 2. The clamping platform 3 is machined into a stepped shape, with the vertical inner surface of the step serving as the clamping mating surface. The two sets of clamping platforms 3 are arranged opposite each other, and the area between them constitutes the clamping station. The fixed part 4 is placed inside the clamping station, with the bottom surface of the fixed part 4 adhering to the upper surface of the support platform 2, and the outer walls on the left and right sides of the fixed part 4 adhering to the inner stepped side walls of the clamping platforms 3 on both sides, thus completing multi-directional limiting clamping.

[0027] Through the above technical solution: In use, an external force is manually applied to rotate the support platform 2. The support platform 2 drives the central groove 9 to rotate synchronously. The inner wall of the central groove 9 presses against the protrusion 11 on the surface of the fixing column 10, generating a reverse force, and the support platform 2 shifts radially. The end of the connecting rod 13 extending into the central groove 9 is blocked by the fixing column 10, pushing the movable block 6 to slide towards the bottom of the assembly groove 5. The movable block 6 compresses the spring 7, and the movable block 6 simultaneously pulls the clamping platform 3 outward, expanding the clamping station space, allowing the fixed part 4 to be inserted or removed. After the external force of rotating the support platform 2 is removed, the spring 7, which is in a compressed state, elastically resets, pushing the movable block 6 to slide towards the through groove 12, causing the clamping platform 3 to retract inward, forming a clamping constraint on the fixed part 4 inside the station.

[0028] The base 1 has a completely flat bottom surface, reducing the likelihood of sliding or tipping when placed on the painting workbench. The fixing post 10 is assembled using threaded posts 15 and threaded grooves 14. The support platform 2, elastic components, and base 1 can be disassembled individually, facilitating the disassembly, inspection, and replacement of easily worn parts such as springs 7 and connecting rods 13, simplifying the maintenance process. The threaded assembly method reduces assembly gaps, ensuring the fixing post 10 remains vertical after installation, reducing the probability of tilting during long-term use, and providing auxiliary support for the clamping and opening / closing mechanism.

[0029] The protrusion 11 abuts against the inner wall of the central groove 9, which can constrain the maximum rotation angle of the support platform 2, reduce the excessive compression of the spring 7 and accelerate the elastic decay caused by excessive rotation of the support platform 2, and extend the service life of the spring 7. The protrusion 11 forms a blocking structure and constitutes a rotation transmission fulcrum. Rotating the support platform 2 can link the clamping structures at both ends, eliminating the need to operate the clamps on both sides separately. All clamping and opening operations can be completed with one hand, which is suitable for scenarios where one person is carrying out model painting work. The protrusion 11 is evenly distributed around the circumference, so that the force is evenly distributed when the support platform 2 rotates, reducing the phenomenon of one-sided jamming and the difference in the opening range of the clamping platforms 3 at both ends.

[0030] The through slot 12 connects the assembly slot 5 and the central slot 9. The connecting rod 13 adopts a linear transmission form, which has a shorter force transmission path and less energy loss. When the bearing platform 2 rotates, the clamping platform 3 responds quickly to the opening and closing action, and the external force consumed during operation is less. The end of the connecting rod 13 abuts against the fixed column 10 to complete the power transmission. The overall structure is simple, and there is no need to add additional rotating shafts or connecting rods. The difficulty of parts processing and assembly is reduced, and the production input cost is controlled. The through slot 12 guides the connecting rod 13, reducing the offset when the connecting rod 13 slides. The sliding progress of the two movable blocks 6 on both sides remains synchronized, the difference in the opening amplitude of the clamping platforms 3 at both ends is reduced, and the clamping force distribution is more uniform.

[0031] Spring 7 is positioned between the bottom of assembly slot 5 and movable block 6. After the external force is removed, spring 7 continues to output clamping force, ensuring that clamping table 3 maintains the clamped part 4 during the painting process, reducing the likelihood of it coming loose on its own. Limiting blocks 8 are installed on both sides of movable block 6, bidirectionally restricting the lateral movement of movable block 6 and reducing the probability of movable block 6 coming off the side of assembly slot 5 during sliding, thus reducing the frequency of equipment malfunctions. Spring 7 and movable block 6 are all housed inside assembly slot 5, with no exposed areas of elastic parts. This reduces the amount of paint adhering to the surface of spring 7 during painting, decreases the frequency of part cleaning, and extends the service life of the entire elastic assembly.

[0032] The stepped inner wall of the clamping platform 3 can accommodate various thicknesses of the fixed parts 4. The stepped, layered structure increases the clamping contact area, reducing the probability of the fixed parts 4 sliding or flipping. The stepped structure provides vertical constraint on the fixed parts 4, reducing the likelihood of positional displacement during spraying airflow impact and brush contact, thus lowering the probability of missed paint application and paint scratches. The symmetrical arrangement of the clamping platforms 3 on both sides provides bidirectional clamping force to the fixed parts 4, reducing the force at a single point and minimizing indentations on the model base surface.

[0033] All clamping and opening actions are accomplished by the rotation of the support platform 2. A single drive structure can synchronously control the clamping platforms 3 at both ends, resulting in a small overall footprint and suitability for painting stations with limited space. The assembly logic of the machine parts is simple, and the processing and assembly procedures are not difficult, keeping costs under control during mass production. The clamping and loading / unloading operations are straightforward, allowing for quick replacement of miniature model bases of different sizes, thus improving the overall efficiency of model painting operations.

[0034] During operation, the bearing platform 2 is manually rotated, which drives the central groove 9 to rotate synchronously. The inner wall of the central groove 9 presses against the protrusion 11 on the fixed column 10 and generates a reverse force, causing the bearing platform 2 to shift radially. After the end of the connecting rod 13 is blocked by the fixed column 10, it pushes the movable block 6 to slide along the inside of the assembly groove 5 and compresses the spring 7. The movable block 6 synchronously drives the clamping table 3 to separate outward, expanding the clamping station space to put in or take out the fixed part 4. After the external force of rotating the bearing platform 2 is removed, the compressed spring 7 elastically resets and pushes the movable block 6 to slide in the opposite direction, pulling the clamping table 3 to retract inward, forming a clamping constraint on the fixed part 4 placed in the clamping station. The limiting blocks 8 on both sides of the movable block 6 can limit its lateral displacement and prevent it from falling out of the assembly groove 5 during operation.
