Description

Technical Field

[0001] This invention belongs to the field of frame processing technology, and particularly relates to a movable placement platform. Background Technology

[0002] Machine tools are machines used to manufacture machines, generally categorized into metal cutting machine tools, forging and pressing machine tools, and woodworking machine tools. Modern mechanical manufacturing employs many methods for processing mechanical parts: in addition to cutting, there are casting, forging, welding, stamping, and extrusion. During the production of rectangular steel frames or window frames, positioning is often necessary during welding or drilling of frame components to facilitate subsequent processing and prevent the rectangular frame from wobbling during operation.

[0003] Existing frame fixing brackets can only be used to position and process rectangular frames of a specific size when fixing the frame. When processing rectangular frames of different models, it is necessary to replace the fixing brackets of the corresponding models, which has poor overall practicality. Moreover, the production cost is high because multiple fixing brackets of different sizes are required during production.

[0004] To address this issue, we propose a mobile placement platform. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art, where existing frame fixing brackets can only be used to position and process rectangular frames of a specific size. When processing rectangular frames of different models, it is necessary to replace the corresponding fixing brackets, resulting in poor overall practicality. Furthermore, the production of multiple fixing brackets of different sizes is costly. Therefore, this invention proposes a movable placement platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A movable placement platform includes a platform body. The top of the platform body has symmetrically opened adjustment cavities along the axial direction. A threaded rod is transversely arranged in the adjustment cavity. A sliding block is sleeved on the threaded rod in the adjustment cavity. Two threads with opposite helical directions are symmetrically opened on the threaded rod. The sliding block and the threaded rod are threadedly engaged. An adjustment motor that drives the threaded rod to rotate is installed on the platform body. A support assembly for auxiliary frame support is installed at the middle section of the platform body and on the two sliding blocks.

[0008] The support assembly includes a support platform with a rotating meshing gear at its center. Transmission gear plates are slidably arranged on both sides of the support platform corresponding to the meshing gear. The outer edge of the meshing gear meshes with the side adjacent to the transmission gear plates. Symmetrical slide rails are provided on the support platform, and sliders are slidably arranged within these rails. One end of each transmission gear plate is fixed to the slider. A groove extends from the top of the slider, and an auxiliary frame support plate is fixed to the top of the slider. A rotating rod is fixed to the top of the meshing gear. A rotating cavity for the rotating rod to rotate is provided at the center of the top of the support platform. A positioning hole is provided on the outer edge of the top of the rotating cavity. A positioning assembly that mates with the positioning hole is installed at the top of the rotating rod.

[0009] As a further preferred embodiment, the positioning assembly includes a fixed cylinder fixed at the top of the rotating rod, a positioning pin slidably inserted inside the fixed cylinder, the bottom of the positioning pin being inserted into the positioning hole, a sleeve fixed at the top of the positioning pin, a pull ring fixed at the top of the sleeve, and a return spring sleeved inside the fixed cylinder corresponding to the outer edge of the sleeve.

[0010] As a further preferred embodiment, the positioning holes are provided in a plurality of form, and the plurality of positioning holes are arranged in a fan shape on the top of the rotating cavity with the center of the support platform as the center.

[0011] As a further preferred embodiment, the vertical cross-section of the slider is inverted T-shaped, and a sliding rod is installed on the slider and fixed inside the slide rail.

[0012] As a further preferred embodiment, a limiting component for limiting the outer edge of the auxiliary frame is installed at the top outer edge of the support body, and several limiting components are symmetrically arranged on the inner edge of the support body.

[0013] As a further preferred embodiment, the limiting component includes a fixed frame fixed at the top of the support body, a sliding rod installed through the fixed frame, a support plate fixed at one end of the sliding rod near the center of the support body, a positioning knob installed at the top center of the fixed frame, the fixed frame and the positioning knob being threadedly engaged, and the bottom of the positioning knob resting on the sliding rod.

[0014] As a further preferred embodiment, a scale plate is embedded at the top of the sliding rod, with the zero mark of the scale plate located at the end of the top of the sliding rod near the support plate.

[0015] As a further preferred embodiment, pulleys are symmetrically installed at the bottom outer edge of the support body, and snap-fit ​​frames are installed at both ends of the support body, the snap-fit ​​frames being snapped onto the guide rail.

[0016] As a further preferred embodiment, a guide block is rotatably provided at the top of the snap-fit ​​frame, a sliding groove is provided at the bottom of the support body, a guide rod is horizontally fixed in the sliding groove, the guide block is sleeved on the guide rod, and a balance spring is sleeved on both sides of the guide rod corresponding to the guide block.

[0017] As a further preferred embodiment, a ball bearing is embedded on the inner side of the snap-fit ​​frame, and the outer edge of the ball bearing is attached to the outer side of the guide rail.

[0018] In summary, the technical effects and advantages of this invention are as follows: This movable placement platform, through the cooperation between the threaded rod and sliding block set in the adjustment cavity and the support components thereon, can move the support components to the corresponding positions according to the different lengths of the rectangular frame during operation, supporting both ends of the frame. After supporting both ends of the frame, the rotating rod can be directly rotated to drive the meshing gear to rotate, thereby causing the transmission gear plate to move and driving the sliding block to move, thus causing the end support plates to move outward to support the two inner sides of the rectangular frame, and thus supporting the four corners of the rectangular frame. This can effectively position rectangular frames of different sizes, minimizing the need to change different fixing frames according to different sizes of rectangular frames during production, and reducing the overall production cost.

[0019] By setting a limiting component at the top outer edge of the support body, the outer side of the frame is supported by the support plate during operation, so as to avoid the rectangular frame being pushed outward excessively during the support process of the limiting component, and to ensure that the rectangular frame does not undergo large deformation during the positioning and fixing process.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Reference Figure 1 and Figure 2 A movable placement platform includes a platform body 1. The top of the platform body 1 has symmetrically arranged adjustment cavities along the axial direction. A threaded rod 42 is transversely arranged through each adjustment cavity. A sliding block 41 is sleeved on the threaded rod 42 within the adjustment cavity. Two threads with opposite helical directions are symmetrically arranged on the threaded rod 42. The sliding block 41 and the threaded rod 42 are threadedly engaged. An adjustment motor 43 is installed on the platform body 1 to drive the threaded rod 42 to rotate. Auxiliary frame supports are installed at the middle section of the platform body 1 and on the two sliding blocks 41. Support assembly 3 includes a support platform 4, a rotating meshing gear 6 at the center of the support platform 4, and transmission gear plates 7 slidably arranged on both sides of the support platform 4 corresponding to the meshing gear 6. The outer edge of the meshing gear 6 meshes with the side adjacent to the transmission gear plate 7. The support platform 4 is symmetrically provided with slide rails, and a slider 8 is slidably arranged in the slide rails. One end of the transmission gear plate 7 is fixed to the slider 8. The top of the slider 8 extends out of the slide groove, and a support plate 9 for auxiliary frame support is fixed at the top of the slider 8. A rotating rod 5 is fixed at the top of the meshing gear 6.

[0029] By cooperating with the threaded rod 42 and the sliding block 41, the position of the sliding block 41 can be adjusted according to the different lengths of the frame during operation, thus facilitating the support of square frames of different lengths. Through the support component 3, during operation, the rotating rod 5 drives the meshing gear 6 to rotate, and the meshing gear 6 meshes with the transmission gear plate 7. When the transmission gear plate 7 moves, it drives the slider 8 to move. During the movement of the slider 8, it drives the support plate 9 to move to both sides. The four support plates 9 at both ends of the support component 3 support the four corners of the frame, thereby supporting the four corners of the rectangular frame. This allows for effective positioning of rectangular frames of different sizes during operation, minimizing the need to change different fixing frames for different sizes of rectangular frames during production, and reducing overall production costs.

[0030] The vertical cross-section of the slider 8 is inverted T-shaped. A slide rod 81 is installed on the slider 8 and fixed in the slide rail. By setting the slider 8 to be inverted T-shaped, it can be ensured that the slider 8 can be stably locked in the slide groove. The slide rod 81 can ensure that the slider 8 can slide stably laterally under the action of the slide rod 81 during the operation, and avoid the occurrence of misalignment of the slider 8 as much as possible.

[0031] Reference Figure 1 , Figure 3 and Figure 4 As shown, a rotating cavity for rotating rod 5 to rotate is provided at the top center of the support platform 4. A positioning hole 52 is provided at the outer edge of the top of the rotating cavity. A positioning component 51 that cooperates with the positioning hole 52 is installed at the top of the rotating rod 5. The positioning component 51 includes a fixed cylinder 511 fixed at the top of the rotating rod 5. A positioning pin 512 is slidably inserted into the fixed cylinder 511. The bottom of the positioning pin 512 is inserted into the positioning hole 52. A sleeve 514 is fixed at the top of the positioning pin 512. A pull ring is fixed at the top of the sleeve 514. A return spring 513 is sleeved and installed inside the fixed cylinder 511 at the outer edge of the sleeve 514.

[0032] With the positioning component 51 in place, the positioning pin 512 in the positioning component 51 is inserted into the positioning hole 52 during the rotation of the rotating rod 5, thus completing the overall positioning of the rotating rod 5. This ensures that the rotating rod 5 will not reset or loosen during the support and positioning process of the support component 3, which facilitates the subsequent processing of the frame.

[0033] The aforementioned positioning holes 52 are provided in a plurality of manner. The plurality of positioning holes 52 are arranged in a fan shape at the top of the rotating cavity with the center of the support platform 4 as the center. Through the fan-shaped arrangement of positioning holes 52, it can be ensured that the rotating rod 5 can be effectively positioned at any angle during operation.

[0034] Reference Figure 1 and Figure 5As shown, a limiting component 10 for limiting the outer edge of the auxiliary frame is installed at the top outer edge of the support body 1. Several limiting components 10 are symmetrically arranged on the inner edge of the support body 1. The limiting component 10 includes a fixing frame 12 fixed at the top of the support body 1. A sliding rod 11 is installed through the fixing frame 12. A support plate 14 is fixed at one end of the sliding rod 11 near the center of the support body 1. A positioning knob 13 is installed at the top center of the fixing frame 12. The fixing frame 12 and the positioning knob 13 are threaded together. The bottom of the positioning knob 13 is abutted on the sliding rod 11.

[0035] By using the limiting component 10, the position of the support plate 14 is pre-adjusted and the support plates 14 on both sides extend by the same length. By rotating the positioning knob 13, the fixed frame 12 and the positioning knob 13 are threaded together, so that the bottom of the positioning knob 13 is placed on the top of the sliding rod 11, thus completing the overall positioning of the sliding rod 11. This avoids the rectangular frame being pushed outward excessively during the pushing and supporting process of the support plate 14 on the limiting component 10, ensuring that the rectangular frame does not undergo large deformation during the positioning and fixing process.

[0036] A scale plate 111 is embedded at the top of the sliding rod 11. The zero mark of the scale plate 111 is located at the top of the sliding rod 11 near the support plate 14. Through the scale plate 111, the overall length of the sliding rod 11 extending out of the fixed frame 12 can be understood during the adjustment process, ensuring that the sliding rods 11 on the limiting components 10 on both sides of the support body 1 are adjusted to equal lengths, and ensuring that the subsequent frame can be fixed at the center of the support body 1.

[0037] Reference Figure 1 and Figure 6 As shown, pulleys 2 are symmetrically installed on the outer edge of the bottom of the support body 1. Snap-fit ​​frames 16 are installed at both ends of the support body 1, snapping onto the guide rail 15. A guide block 162 is rotatably mounted on the top of the snap-fit ​​frame 16. A sliding groove is provided at the bottom of the support body 1, and a guide rod 17 is horizontally fixed within the groove. The guide block 162 is sleeved on the guide rod 17. Balance springs 18 are sleeved on both sides of the guide rod 17 corresponding to the guide block 162. The balance springs 18 ensure that the guide block 162 remains stably positioned in the middle of the guide rod 17 during operation, preventing misalignment of the support body 1 after turning and moving, and avoiding misalignment of the guide block 162.

[0038] The inner side of the aforementioned snap-fit ​​frame 16 is fitted with a ball bearing 161, and the outer edge of the ball bearing 161 is attached to the outer side of the guide rail 15. The ball bearing 161 ensures that the snap-fit ​​frame 16 will not be stuck on the guide rail 15 during operation, and ensures that the snap-fit ​​frame 16 can be stably slidably set on the guide rail 15 for movement.

[0039] Working principle: When it is necessary to support the rectangular frame during operation, the position of the support plate 14 is first adjusted according to the different widths of the frame, and the support plates 14 on both sides extend by the same length. The positioning knob 13 is rotated, and the fixed frame 12 and the positioning knob 13 are threaded together, so that the bottom of the positioning knob 13 is placed on the top of the sliding rod 11, thus completing the overall positioning of the sliding rod 11.

[0040] The frame is placed on top of the support platform 4. The adjusting motor 43 is started, which drives the threaded rod 42 to rotate. The sliding block 41 is threadedly engaged with the threaded rod 42, causing the sliding block 41 to move to both sides. This causes the support assembly 3 on the sliding block 41 to move as a whole. When one side of the support plate 9 is in contact with the inner side of the frame, the adjusting motor 43 stops. At this time, the rotating rod 5 is rotated, which drives the meshing gear 6 to rotate. The meshing gear 6 meshes with the transmission gear plate 7. When the transmission gear plate 7 moves, it drives the slider 8 to move. During the movement of the slider 8, it drives the support plate 9 to move to both sides. The four support plates 9 at both ends of the support assembly 3 support the four corners of the frame, and the support plate 9 at the middle section of the support assembly 3 supports the middle section of the frame.

[0041] During the rotation of the rotating rod 5, the positioning pin 512 in the positioning assembly 51 is inserted into the positioning hole 52 to complete the overall positioning of the rotating rod 5 and prevent the rotating rod 5 from rotating back during the support of the support plate 9. When the frame needs to be disassembled, the sleeve 514 is pulled directly to pull the positioning pin 512, which in turn compresses the return spring 513 and restores the support assembly 3 to its original position.

[0042] When the entire platform body 1 needs to be moved, push the platform body 1 to move it along the guide rail 15. When the platform body 1 needs to turn, the ball 161 slides along the guide rod 17 and compresses the balance spring 18 on one side. When the guide rail 15 is in a straight line, the compressed balance spring 18 ensures that the guide block 162 is at the center of the guide rod 17.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
