Description

Technical Field

[0001] This utility model relates to the technical field of metal structure manufacturing, and more specifically, it relates to a fixed support structure for metal structure manufacturing. Background Technology

[0002] In the field of metal structure manufacturing, drilling of metal rods, such as steel structure connectors, mechanical transmission rods, and frame support columns, is one of the core processes. The drilling accuracy directly determines the fit of subsequent assembly and the overall stability of the structure. As a core auxiliary device during metal rod drilling, the fixed support structure needs to flexibly adjust the fixed spacing and clamping force. Moreover, under the impact force generated during drilling, especially at high speeds, the metal rod must not experience radial sway or axial displacement. Otherwise, it can easily lead to hole diameter deviation, hole position offset, or even cause problems such as metal rod breakage and drilling tool damage.

[0003] An existing fixed support structure for metal structure manufacturing has been found to have the following issues during use: The fixing method is cumbersome and has poor adaptability. When changing metal rods of different diameters or lengths, multiple sets of bolts must be loosened first, the position of the clamp must be manually adjusted or the appropriate clamp must be replaced, and then the bolts must be tightened again for calibration. This method has poor adjustment efficiency and requires a lot of working time, thus resulting in poor practicality. Utility Model Content

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a fixed support structure for manufacturing metal structures, so as to solve the technical problems mentioned in the background art of cumbersome fixing methods and poor adaptability.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a fixed support structure for manufacturing metal structures, including an operating table, a mounting frame on the top of the operating table, a drilling device at the bottom of the mounting frame, a working cavity on the operating table, sliding holes at both ends of the top of the working cavity, connecting blocks slidably disposed within the sliding holes of the two sets of operating table working cavities, sliding plates on the top of the two sets of connecting blocks, mounting blocks on the top of the two sets of sliding plates, connecting components at opposite ends of the two sets of mounting blocks, and clamps on the front and rear sides of opposite ends of the two sets of mounting blocks via the connecting components, placement seats at both ends of the top of the operating table, and adjustment mechanisms at the bottom of the two sets of connecting blocks.

[0006] The present invention is further configured such that the adjustment mechanism includes a bidirectional screw, which is rotatably disposed within the working cavity of the operating table. Both ends of the bidirectional screw are threadedly connected to sliders. The upper and lower ends of the two sets of sliders are respectively slidably engaged with one end of the corresponding working cavity of the operating table. A drive motor is disposed at the front end of the operating table, and the rear output end of the drive motor passes through the operating table and connects to the front end of the bidirectional screw. Sliding components are disposed on both sides of the front and rear ends of the working cavity of the operating table. Connecting plates are slidably disposed on both sides of the working cavity of the operating table via the sliding components. The tops of the two sets of connecting plates are respectively connected to the bottoms of a corresponding set of connecting blocks. Hinges are disposed at opposite ends of the two sets of connecting plates, and opposite ends of the two sets of connecting plates are connected to one end of the two sets of sliders via the hinges. The drive motor and bidirectional screw transmission method replaces the existing manual adjustment. Only the motor needs to be started to quickly complete the clamping plate spacing adjustment. Furthermore, the bidirectional screw drives the sliders to move synchronously, ensuring symmetrical and accurate spacing between the clamping plates on both sides, avoiding spacing deviations caused by manual adjustment, and improving the stability of the metal rod.

[0007] The present invention is further configured such that the hinge assembly includes four sets of support rods, and the left and right ends of the two sets of sliders are respectively hinged to one end of a set of support rods through hinge members, and the opposite ends of the two sets of connecting plates are hinged to the other ends of the corresponding two sets of support rods through hinge members; the hinge assembly composed of four sets of support rods converts the forward and backward movement of the sliders into the left and right movement of the connecting plates, realizing the conversion of force direction, making the adjustment mechanism structure compact, saving working cavity space, reducing the number of parts and the probability of failure compared with the existing complex transmission structure, and the symmetrical distribution design of the support rods ensures that the two sets of connecting plates move synchronously, avoiding the asymmetry of the clamping plate spacing caused by unilateral movement, and further improving the fixing accuracy of the metal rods.

[0008] The present invention is further configured such that the sliding component includes four sets of guide blocks, and each of the four sets of operating table working cavities has a sliding groove on both sides of the front and rear ends. The guide blocks are slidably connected in the sliding grooves of the four sets of operating table working cavities. The front and rear ends of the two sets of connecting plates are respectively connected to the other end of the corresponding set of guide blocks. The cooperation between the guide blocks and the sliding grooves provides precise guidance for the connecting plates, eliminating the need for additional calibration of the clamping plate position after adjustment, reducing operation steps, and improving the efficiency of specification switching.

[0009] The present invention is further configured such that the connecting assembly includes two sets of positioning screws, and grooves are provided on both the front and rear sides of one end of each of the two sets of mounting blocks. Positioning blocks are snapped into the grooves of each of the four sets of mounting blocks, and the other ends of the four sets of positioning blocks are respectively connected to one end of a corresponding set of clamping plates. The grooves of the four sets of mounting blocks are respectively provided with threaded holes through the corresponding set of positioning blocks. The outer sides of the four sets of positioning screws are threadedly connected to the corresponding positioning blocks and mounting blocks through the threaded holes. The snap-fit ​​cooperation between the positioning blocks and the grooves, combined with the threaded fixation of the positioning screws, enables quick disassembly and replacement of the clamping plates. The clamping plates can be flexibly replaced according to metal rods of different diameters, improving the adaptability of the device to metal rods of different specifications. The threaded connection of the positioning screws has self-locking properties, and the clamping plate is stable after fixing, and will not loosen due to drilling impact, ensuring that the metal rod is firmly clamped.

[0010] The present invention is further configured such that each of the four sets of positioning screws is provided with a rotating handle at the top; the rotating handle increases the force application area of ​​the positioning screw, further improving the ease of use and practicality of the device.

[0011] The present invention is further provided with anti-slip pads on the clamping surfaces of the four sets of clamping plates; by increasing the friction, the metal rod is ensured to remain in a fixed position during the drilling process. At the same time, the flexible deformation characteristics of the anti-slip pads can buffer the clamping force of the clamping plates on the metal rod, avoiding indentations or scratches on the surface of the metal rod caused by direct contact with the hard clamping plates, thus protecting the appearance and strength of the metal rod.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides a fixed support structure for manufacturing metal structures, which has the following advantages: 1. The connecting block, sliding plate, and mounting block are moved as a whole by the adjustment mechanism, which enables flexible adjustment of the clamping plate spacing. There is no need to disassemble and replace the fixture, which greatly shortens the specification changeover time and improves processing efficiency. The connecting components can independently adjust the clamping plate position to adapt to the clamping requirements of metal rods of different diameters. With the auxiliary support of the placement seat for the metal rod, it is possible to prevent the metal rod from sagging or shaking due to lack of support during drilling. The integrated design of the mounting frame and drilling device ensures accurate drilling position and reduces subsequent rework. At the same time, the front and rear sides of the clamping plate are distributed to ensure that the metal rod is subjected to uniform force, avoids surface indentation during clamping, protects the integrity of the metal rod, and adapts to the diverse metal structure manufacturing needs.

[0018] Please see Figure 1-5 A fixed support structure for manufacturing metal structures includes an operating table 1, a mounting frame 2 on the top of the operating table 1, a drilling device 3 at the bottom of the mounting frame 2, a working cavity in the operating table 1, sliding holes at both ends of the top of the working cavity in the operating table 1, connecting blocks 4 slidably disposed in the sliding holes of the two sets of working cavities in the operating table 1, sliding plates 5 on the top of the two sets of connecting blocks 4, mounting blocks 6 on the top of the two sets of sliding plates 5, connecting components at opposite ends of the two sets of mounting blocks 6, and clamping plates 7 on the front and rear sides of opposite ends of the two sets of mounting blocks 6 through the connecting components, placement seats 8 at both ends of the top of the operating table 1, and adjustment mechanisms at the bottom of the two sets of connecting blocks 4.

[0019] In this embodiment, when using the fixed support structure, the metal rod to be drilled is first placed on the placement seats 8 at the front and rear ends of the top of the operating table 1. According to the specifications of the metal rod, the adjustment mechanism at the bottom of the two sets of connecting blocks 4 is operated. The adjustment mechanism drives the connecting blocks 4 to slide along the sliding hole at the top of the working cavity of the operating table 1. The connecting blocks 4 drive the top sliding plate 5 to move synchronously. The mounting block 6 at the top of the sliding plate 5 is adjusted with the sliding plate 5 so that the clamping plate 7 at the opposite end of the two sets of mounting blocks 6 is aligned with the two ends of the metal rod until the clamping plate 7 is attached to the surface of the metal rod and clamped and fixed. After the fixing is completed, the drilling device 3 at the bottom of the mounting bracket 2 at the top of the operating table 1 is started to drill the metal rod. After the processing is completed, the connecting assembly is reversed to loosen the clamping plate 7 and the metal rod can be removed.

[0020] More specifically, when adjusting the clamping plate 7 according to the diameter of the metal rod, first, the positioning block 16 at one end of the clamping plate 7 is inserted into the grooves on the front and rear sides of the opposite end of the mounting block 6, so that the positioning block 16 is aligned with the groove and the threaded holes of the two are coaxial. Then, the outer side of the positioning screw 15 is passed through the threaded hole and the positioning screw 15 is rotated to make it threadedly connected with the positioning block 16 and the mounting block 6. The positioning block 16 is fixed in the groove through the threaded transmission, thereby fixing the clamping plate 7 on the mounting block 6.

[0021] Please see Figure 1 and Figure 4 As one implementation of the adjustment mechanism: The adjustment mechanism includes a bidirectional screw 9. The bidirectional screw 9 is rotatably arranged inside the working cavity of the operating table 1. The front and rear ends of the bidirectional screw 9 are threadedly connected to sliders 10. The upper and lower ends of the two sets of sliders 10 are respectively slidably attached to one end of the working cavity of the corresponding operating table 1. A drive motor 11 is arranged at the front end of the operating table 1. The rear output end of the drive motor 11 passes through the operating table 1 and is connected to the front end of the bidirectional screw 9. Sliding components are arranged on both sides of the front and rear ends of the working cavity of the operating table 1. Connecting plates 12 are slidably arranged on both sides of the working cavity of the operating table 1 through the sliding components. The top of the two sets of connecting plates 12 is respectively connected to the bottom of the corresponding set of connecting blocks 4. A hinge component is arranged at the opposite end of the two sets of connecting plates 12. The opposite end of the two sets of connecting plates 12 is connected to one end of the two sets of sliders 10 through the hinge component.

[0022] Specifically, when adjusting the spacing of the clamping plates 7, the drive motor 11 at the front end of the operating table 1 is started. The output end of the drive motor 11 drives the bidirectional screw 9 in the working cavity to rotate. The sliders 10 at the front and rear ends of the outer side of the bidirectional screw 9 move synchronously with the screw due to the threaded connection. When the sliders 10 move, the connecting plates 12 are moved by the hinge components at opposite ends of the two sets of connecting plates 12. The connecting plates 12 slide along the sliding components at the front and rear ends of the working cavity of the operating table 1. The connecting block 4 connected to the top of the connecting plate 12 slides synchronously along the sliding hole with the connecting plate 12, thereby driving the slide plate 5, the mounting block 6, and the clamping plates 7 to adjust their positions. When the spacing of the clamping plates 7 is adapted to the length of the metal rod, the drive motor 11 is turned off, the bidirectional screw 9 stops rotating, the sliders 10, the connecting plates 12, and the connecting block 4 are fixed in position, and the clamping plates 7 maintain a stable spacing, so that the metal rod can be clamped and drilled.

[0023] Please refer to Figures 2-4 As a further embodiment of the adjustment mechanism: the hinge assembly includes four sets of support rods 13, the left and right ends of the two sets of sliders 10 are respectively hinged to one end of a set of support rods 13 through hinge members, and the opposite ends of the two sets of connecting plates 12 are all hinged to the other ends of the corresponding two sets of support rods 13 through hinge members.

[0024] Specifically, when the slider 10 moves under the drive of the bidirectional screw 9, the support rods 13 connected at its left and right ends by hinges rotate synchronously. The other end of the support rod 13 is connected to the opposite end of the connecting plate 12 by a hinge. When the slider 10 moves closer, the support rods 13 push the connecting plate 12 to move outward along the sliding assembly. The connecting plate 12 drives the connecting block 4, the slide plate 5, and the mounting block 6 to move outward, increasing the distance between the clamping plates 7. When the slider 10 moves away, the support rods 13 pull the connecting plate 12 to move inward, decreasing the distance between the clamping plates 7. Regardless of the direction of movement of the slider 10, the four sets of support rods 13 always maintain symmetrical rotation, ensuring that the movement amplitude of the two sets of connecting plates 12 is consistent, thereby making the movement distance of the connecting block 4, the slide plate 5, and the mounting block 6 on both sides the same, and the adjustment of the distance between the clamping plates 7 symmetrical.

[0025] In summary, the overall equipment is in use (or running): In use, insert the positioning block 16 at one end of the clamping plate 7 into the groove of the mounting block 6, rotate the handle 17 to make the positioning screw 15 pass through the threaded hole of the mounting block 6 and the positioning block 16 and tighten it, then place the metal rod to be drilled on the placement seats 8 at the front and rear ends of the top of the operating table 1, start the drive motor 11 at the front end of the operating table 1, the output end of the drive motor 11 drives the bidirectional screw 9 in the working cavity to rotate, the sliders 10 at the front and rear ends of the bidirectional screw 9 slide along the working cavity, and the left and right ends of the sliders 10 drive the support rod 13 to rotate through the hinges. The other end of the strut 13 pulls or pushes the connecting plate 12 through the hinge. The guide blocks 14 at the front and rear ends of the connecting plate 12 slide along the sliding grooves on the front and rear sides of the working cavity. The connecting block 4 at the top of the connecting plate 12 moves synchronously along the sliding hole at the top of the working cavity. The connecting block 4 drives the top sliding plate 5 and the mounting block 6 on the sliding plate 5 to adjust their positions so that the clamping plates 7 of the two sets of mounting blocks 6 are aligned with the two ends of the metal rod until the anti-slip pads 18 on the clamping surface of the clamping plate 7 are in contact with the surface of the metal rod, clamping the metal rod. Then, the drilling device 3 at the bottom of the mounting frame 2 at the top of the operating table 1 is started to drill holes in the metal rod.

[0026] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
