Description

Technical Field

[0001] This utility model relates to the field of steel component processing technology, and in particular to a component clamping assembly and a steel structure clamping device. Background Technology

[0002] During the processing and installation of steel components, it is often necessary to clamp and fix the steel components to ensure the accuracy and safety of subsequent operations. However, current clamping equipment used for steel components still has many problems in practical use.

[0003] In existing technologies, clamping devices mostly employ basic clamping structures, providing clamping force only in one direction and lacking auxiliary fixing functions in the vertical direction. This makes steel components prone to displacement or loosening under stress, affecting construction accuracy. Furthermore, traditional devices often require step-by-step operation of the clamping and pressing components, increasing operational complexity and reducing efficiency. Additionally, for steel components with curved surfaces or irregular cross-sections, ordinary clamps struggle to achieve stable contact, posing a risk of insecure clamping or damage to the component's surface.

[0004] To address the aforementioned problems, this utility model document proposes a component clamping assembly and a steel structure clamping device. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing technologies, such as insufficient clamping stability of traditional clamping devices, cumbersome operation, poor adaptability to irregularly shaped components, and easy displacement or damage. Therefore, a component clamping assembly and steel structure clamping device are proposed.

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

[0007] A component clamping assembly, comprising:

[0008] The support base has two clamping plates on its top, which cooperate to clamp the steel component; a connecting frame is fixedly connected to the side of the two clamping plates that is far apart from each other; a plurality of first support frames are fixedly connected to the top of the support base; and two connecting frames are slidably connected to the inner walls of two adjacent first support frames.

[0009] A drive assembly is disposed below the support base and is connected to the connecting frame, used to drive the two clamping plates to move closer and further apart;

[0010] The four sets of pressing components are arranged in pairs and staggered on the support base for vertically pressing and fixing the steel components.

[0011] When the driving component moves the two clamping plates, it simultaneously drives the pressing component to move, thereby achieving the linkage between horizontal clamping and vertical pressing.

[0012] In one possible design, the drive assembly includes two limiting grooves formed at the top of the support base, with L-shaped movable frames slidably connected to the inner walls of both limiting grooves, and each L-shaped movable frame being fixedly connected to an adjacent connecting frame; the bottom of the support base is provided with a mounting groove, with a movable block slidably connected to the inner wall of the mounting groove, and hinged brackets fixedly mounted on both sides of the movable block, with connecting rods rotatably connected to each of the two hinged brackets, and the other ends of the two connecting rods being rotatably connected to adjacent L-shaped movable frames; a cylinder is fixedly connected to the mounting groove, and the piston rod of the cylinder is fixedly connected to the movable block.

[0013] In one possible design, grooves are provided on the sides of the two clamping plates that are close to each other, and the inner walls of the two grooves are arc-shaped to clamp the arc-shaped steel components; rectangular slots are provided on one side of the two grooves to clamp the plate-shaped steel components.

[0014] In one possible design, the pressing assembly includes a second support frame fixedly connected to the top of the support base. A rotating plate is hinged to the top of the second support frame. A pressing rod is slidably connected to one end of the rotating plate. A pressing head is fixedly connected to the bottom end of the pressing rod. The pressing head is used to abut against the top of the steel component. A spring is sleeved on the outer wall of the pressing rod. The two ends of the spring are respectively connected to the rotating plate and the pressing rod, so that the pressing head always presses against the steel component.

[0015] In one possible design, the pressing assembly further includes a lifting rod hinged to the other end of the rotating plate, a lifting groove is provided on one side of the support base, and the lifting rod is slidably connected to the inner wall of the lifting groove; a fixing plate is fixedly connected to the bottom of the lifting rod, and an abutment groove is provided inside the fixing plate, the abutment groove being composed of a horizontal groove and an inclined groove.

[0016] In one possible design, connecting rods are fixedly connected inside both L-shaped movable frames. The two ends of the two connecting rods pass through adjacent abutment grooves and slide in contact with the inner wall of the abutment grooves. When the L-shaped movable frames move horizontally, the connecting rods slide in the abutment grooves, driving the lifting rods to rise and fall.

[0017] In one possible design, redundant slots are provided at the hinge point between the rotating plate and the lifting rod to avoid rotational interference.

[0018] In one possible design, the pressing head is a sphere.

[0019] A steel structure clamping device includes: a component clamping assembly as described in any one of the above.

[0020] In this application, when in use, the steel component to be fixed is placed on top of the support base and between the two clamping plates. The cylinder of the drive assembly is activated, and the piston rod extends to push the moving block to move away from the center along the mounting slide. At this time, under the drive of the connecting rod, the two L-shaped moving frames can approach each other along the limiting groove. Then, by pushing the connecting frame and driving the clamping plates to approach each other, the steel component can be clamped. If the steel component has a curved surface or other shapes, the grooves or rectangular slots of the clamping plates can help to achieve stable clamping.

[0021] When the L-shaped moving frame moves, the connecting rod on it slides along the horizontal groove of the fixed plate towards the center and the inclined groove outwards. When the connecting rod slides from the inclined groove to the horizontal groove, it can push the lifting rod to rise along the lifting slide, which in turn can drive the rotating plate to rotate around the second support frame, so that the pressing rod and pressing head move closer to the top of the steel component. The spring can drive the pressing head to always press against the top of the steel component; at the same time, the four sets of pressing components are staggered and cooperate to complete the stable pressing of the steel component in the vertical direction.

[0022] When removing the component, the piston rod of the control cylinder retracts, pulling the moving block closer to the center. At this time, the connecting rod gradually moves to the same horizontal line, which allows the two L-shaped moving frames to move away from each other, thereby separating the two clamping plates and releasing the horizontal clamping of the steel component. Simultaneously, the connecting rod slides back from the horizontal groove to the inclined groove, the lifting rod moves down and drives the rotating plate to rotate in the opposite direction, and the pressing head disengages from the top of the steel component, allowing the steel component to be removed.

[0023] Throughout the process, all components work together in unison, eliminating the need for separate control of pressing components, which simplifies operation and allows for stable clamping of steel components of various specifications.

[0024] Beneficial effects: In this utility model, the component clamping assembly and steel structure clamping device, through the linkage and cooperation of each component, can drive the two clamping plates to move closer to each other to achieve horizontal clamping during the operation of the drive assembly, while simultaneously driving four sets of pressing components to complete vertical pressing and fixing; this structure does not require separate control of the pressing components, reduces operation steps, avoids the problem of poor clamping effect caused by asynchronous operation, and effectively improves work efficiency;

[0025] In this utility model, the component clamping assembly and steel structure clamping device are provided with an arc-shaped groove and a rectangular groove on the side of the clamping plates that are close to each other. The arc-shaped groove can fit tightly with the surface of the steel component with an arc surface, and the rectangular groove can be adapted to steel components with protruding plate-like structures. This greatly improves the fit with the steel component when clamping horizontally, avoids the situation of clamping loosening, and meets the stable clamping requirements of steel components of different shapes.

[0026] In this utility model, the component clamping assembly and steel structure clamping device have a spring in the pressing assembly that can drive the pressing rod to keep the pressing head pressed against the top of the steel component. With the rotation of the rotating plate around the second support frame, the position of the pressing head can be adjusted according to the height difference of the steel component. It can adapt to steel components of different specifications without disassembling or adjusting the structure of the pressing assembly, reducing the adjustment steps when changing steel components and avoiding frequent interruptions to the work process.

[0027] In this invention, the device achieves synchronized horizontal clamping and vertical pressing through the linkage of the drive component and the pressing component. While the cylinder drives the clamping plate to move horizontally to clamp the component, the pressing component is automatically pushed down through the cooperation of the connecting rod and the abutment groove, so that the pressing head is always pressed against the top of the component under the action of the spring. This integrated linkage mechanism simplifies the operation steps and improves work efficiency. The four sets of staggered pressing components ensure stable force in the vertical direction and effectively prevent component displacement. The grooves and rectangular structures on the clamping plate enhance the adaptability to curved or irregularly shaped components, improving the stability and versatility of clamping.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] In one embodiment: Refer to Figure 1-5 A component clamping assembly includes: a support base 1, a drive assembly, a clamping mechanism, and four sets of pressing assemblies.

[0036] In this embodiment, two clamping plates 4 are provided on the top of the support base 1. The two clamping plates 4 cooperate with each other to clamp and fix the steel component. A connecting frame 3 is fixedly installed on the side of each clamping plate 4 that is far apart from each other. Multiple first support frames 2 are fixedly installed on the top of the support base 1. The two connecting frames 3 are slidably connected to the inner walls of two adjacent first support frames 2. By guiding the connecting frames 3 through the first support frames 2, it can be ensured that the clamping plates 4 always maintain stable horizontal movement during the movement, avoiding deviation that would affect the clamping effect.

[0037] In this embodiment, the drive assembly is located below the support base 1 and is used to move the two clamping plates 4 closer together and further apart. The drive assembly includes two limiting grooves 5 opened on the top of the support base 1. The two limiting grooves 5 are respectively located near the two sides of the support base 1. The inner wall of each limiting groove 5 is slidably connected to an L-shaped moving frame 6. The top ends of the two L-shaped moving frames 6 are respectively fixedly connected to one side of the adjacent connecting frame 3. The limiting grooves 5 can restrict the movement direction of the L-shaped moving frame 6 to ensure that the L-shaped moving frame 6 will not deviate from the preset trajectory when it drives the connecting frame 3 to move.

[0038] Furthermore, in this embodiment, the bottom of the support base 1 forms an installation groove 13 through a fixedly installed bracket. A movable block 14 is slidably installed inside the installation groove 13. Hinged brackets 15 are fixedly installed on both sides of the movable block 14. A connecting rod 16 is rotatably connected inside each hinged bracket 15. The other ends of the two connecting rods 16 are rotatably connected to one end of the L-shaped movable frame 6 of the adjacent L-shaped movable frame 6, respectively. A cylinder 17 is fixedly installed inside the installation groove 13. One end of the piston rod of the cylinder 17 is fixedly connected to one side of the movable block 14. After the cylinder 17 is started, the piston rod of the cylinder 17 can push the movable block 14 to slide in the installation groove 13. When the movable block 14 moves, it will drive the connecting rod 16 to rotate through the hinged bracket 15. During the rotation of the connecting rod 16, it will push or pull the L-shaped movable frame 6 to slide in the limiting groove 5, and then drive the connecting frame 3 to move through the L-shaped movable frame 6, so as to realize the approach or distance of the two clamping plates 4 and complete the clamping or loosening operation of the steel component.

[0039] In this embodiment, grooves 22 are formed on the sides of the two clamping plates 4 that are close to each other. The inner walls of both grooves 22 are arc-shaped. When it is necessary to clamp a steel component with an arc surface, the grooves 22 with arc-shaped inner walls can better fit the arc surface of the steel component, thereby achieving stable clamping of the arc-shaped steel component and preventing the steel component from sliding during clamping. At the same time, rectangular slots are formed on one side of both grooves 22. For steel components with protruding plate-like structures, the rectangular slots can complete the locking and clamping of the corresponding protruding plate-like structures, which can further improve the clamping stability of the clamping plates 4 for various steel components with different structures and expand the applicability of the component.

[0040] In this embodiment, four sets of pressing components work in pairs and are staggered to complete the vertical pressing and fixing of the steel component to be fixed. Each pressing component includes a second support frame 8 fixedly installed on the top of the support base 1. A rotating plate 9 is hinged to the top of the second support frame 8, and the rotating plate 9 can rotate freely around the hinge point. One end of the rotating plate 9 slides through a pressing rod 11, which can move up and down along the through hole of the rotating plate 9. A pressing head 20 is fixedly installed at the bottom of the pressing rod 11, and the pressing head 20 abuts against the top of the steel component to be clamped. A spring 21 is sleeved on the outer wall of the pressing rod 11, positioned above the rotating plate 9. The bottom end of the spring 21 is fixedly connected to the top of the rotating plate 9 via a spring 21 seat, and the top end of the spring 21 is fixedly connected to the outer wall of the pressing rod 11 near the top end via a spring 21 seat. Under the elastic action of the spring 21, the spring 21 continuously applies a downward force to the pressing rod 11, driving the pressing rod 11 to move downwards, thereby ensuring that the pressing head 20 always presses against the top of the corresponding steel component. When different steel components have different specifications, resulting in different heights, the rotating plate 9 can rotate around the hinge point at the top of the second support frame 8. In conjunction with the up-and-down movement of the pressing rod 11 under the action of the spring 21, the pressing head 20 can always maintain the contact state with the top of the steel component, thereby completing the contact and fixation of steel components of various specifications and improving the adaptability of the component to steel components of different specifications.

[0041] In this embodiment, the pressing assembly also includes a lifting rod 10 hinged to the other end of the rotating plate 9. A lifting groove 12 corresponding to the lifting rod 10 is provided on one side of the support base 1. The lifting rod 10 is slidably connected to the inner wall of the lifting groove 12. The lifting groove 12 can restrict the movement direction of the lifting rod 10, ensuring that the lifting rod 10 can only move up and down in the vertical direction. A fixing plate 18 is fixedly installed at the bottom of the lifting rod 10. An abutment groove 19 is provided inside the fixing plate 18. The abutment groove 19 is composed of a horizontal groove and an inclined groove, and the horizontal groove is located on the side of the inclined groove closer to the center of the support base 1.

[0042] In this embodiment, connecting rods 7 are fixedly inserted inside both L-shaped movable frames 6. The two ends of the two connecting rods 7 respectively pass through adjacent abutment grooves 19, and the outer walls of the two connecting rods 7 slide against the inner walls of the corresponding abutment grooves 19. When the driving assembly drives the two L-shaped movable frames 6 to move horizontally, the L-shaped movable frames 6 will drive the connecting rods 7 to move horizontally synchronously. During the movement, the outer walls of the connecting rods 7 will slide relative to the inner walls of the abutment grooves 19. Since the abutment groove 19 includes a horizontal groove and an inclined groove, when the connecting rod 7 moves from the horizontal groove of the abutment groove 19 to the inclined groove, the inner wall of the inclined groove will exert a vertical force on the connecting rod 7, thereby driving the fixed plate 18 and the lifting rod 10 to move up and down along the lifting slide 12; when the connecting rod 7 moves in the horizontal groove, the lifting rod 10 remains stable. Through this cooperation, the lifting drive of multiple lifting rods 10 can be realized when the two L-shaped moving frames 6 move horizontally, thereby driving the rotating plate 9 to rotate around the hinge point at the top of the second support frame 8, providing power for the pressing assembly to adapt to steel components of different specifications.

[0043] A steel structure clamping device includes the aforementioned component clamping assembly. By integrating the component clamping assembly into the steel structure clamping device, this device utilizes the clamping and vertical pressing functions of the component clamping assembly to achieve stable clamping of steel components of different specifications and structures. This meets the clamping needs of steel components in steel structure processing and installation scenarios, improving the practicality and applicability of the steel structure clamping device.

[0044] This application can be used in the field of steel component processing technology, or in other fields applicable to this application.

[0045] In another embodiment: Reference Figure 2 , 5 A component clamping assembly and steel structure clamping equipment are applied to the field of steel component processing technology.

[0046] In this embodiment, redundant slots are provided at the hinge positions of multiple rotating plates 9 and corresponding lifting rods 10. When the rotating plate 9 rotates around the hinge point at the top of the second support frame 8, the relative position of the rotating plate 9 and the lifting rod 10 will change. The redundant slots can provide sufficient space for movement, avoid interference between the rotating plate 9 and the corresponding lifting rod 10 during rotation, and ensure that the movement of the rotating plate 9 and the lifting rod 10 can proceed smoothly without affecting the overall operation of the pressing component.

[0047] In this embodiment, the pressing head 20 is preferably a sphere to ensure that it can provide a good pressing effect on the steel component below at all angles.

[0048] However, as is well known to those skilled in the art, the working principle and wiring method of 17 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selection according to their needs or convenience.

[0049] The working principle and usage process of this technical solution are as follows: When in use, place the steel component to be fixed on top of the support base 1 and between the two clamping plates 4. Start the cylinder 17 of the drive assembly. The piston rod extends and pushes the moving block 14 to move away from the center along the mounting slide 13. At this time, under the drive of the connecting rod 16, the two L-shaped moving frames 6 can approach each other along the limiting groove 5. Then, by pushing the connecting frame 3 and driving the clamping plates 4 to approach each other, the steel component can be clamped. If the steel component has an arc surface or other shapes, the groove 22 and rectangular groove of the clamping plate 4 can help to complete the stable clamping.

[0050] When the L-shaped movable frame 6 moves, the connecting rod 7 on it slides along the horizontal groove of the abutment groove 19 of the fixed plate 18 towards the center and the inclined groove outward. When the connecting rod 7 slides from the inclined groove to the horizontal groove, it can push the lifting rod 10 to rise along the lifting slide groove 12, which in turn can drive the rotating plate 9 to rotate around the second support frame 8, so that the pressing rod 11 and the pressing head 20 move closer to the top of the steel component. The spring 21 can drive the pressing head 20 to always press against the top of the steel component; at the same time, the four sets of pressing components are staggered and cooperate to complete the stable pressing of the steel component in the vertical direction.

[0051] When removing the component, the piston rod of the control cylinder 17 retracts, pulling the moving block 14 to move closer to the center. At this time, the connecting rod 16 gradually moves to the same horizontal line, which allows the two L-shaped moving frames 6 to move away from each other, thereby separating the two clamping plates 4 and releasing the horizontal clamping of the steel component. At the same time, the connecting rod 7 slides back from the horizontal groove to the inclined groove, the lifting rod 10 moves down and drives the rotating plate 9 to rotate in the opposite direction, and the pressing head 20 disengages from the top of the steel component, so that the steel component can be removed.

[0052] Throughout the process, all components work together in unison, eliminating the need for separate control of pressing components, which simplifies operation and allows for stable clamping of steel components of various specifications.

[0053] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
