Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering, and in particular relates to a steel structure assembly positioning device. Background Art

[0002] Steel structure riveting welding refers to welding parts such as corbels and parts plates to the main body of the steel structure through riveting welding. Due to the large overall length of the steel structure, when riveting after installation, workers need to climb high places to carry out the operation, which is not only inconvenient to operate, but also greatly increases the risk. Therefore, riveting welding is usually carried out on the ground.

[0003] During riveting and welding, the riveted parts need to be aligned. Manual alignment is usually used for the alignment of smaller parts. However, the error of manual alignment is large. Once the riveting and welding is completed, the parts become one with the main body of the steel structure, which makes it difficult to eliminate the error. In addition, long-term use of manual alignment requires workers to carry the parts, which is labor-intensive. Utility Model Content

[0004] The utility model aims to overcome the problems of large errors and high labor intensity in the manual alignment of riveted parts in the prior art.

[0005] To this end, the utility model provides a steel structure assembly positioning device, including a clamping unit and a driving unit;

[0009] Specifically, the above-mentioned clamping unit also includes a second clamping mechanism; the second clamping mechanism includes a third clamping member and a fourth clamping member; the first clamping member and the fourth clamping member are slidably connected by a first sliding rod; the second clamping member and the third clamping member are slidably connected by a second sliding rod; the first sliding rod and the second sliding rod are respectively threadedly connected to both ends of the second screw rod.

[0010] Specifically, the third clamping member and the fourth clamping member are slidably connected via a fourth sliding rod; the third sliding rod and the fourth sliding rod are respectively threadedly connected to two ends of the first screw rod, and the thread directions of the two ends of the first screw rod are opposite.

[0011] Specifically, the steel structure assembly and positioning device further comprises a support frame; a mounting ring is provided on the support frame; the connecting shaft is movably connected in the mounting ring, and the mounting ring is located between the first bevel gear and the second bevel gear.

[0012] Specifically, a connecting ring is provided on the connecting shaft; the connecting ring is located between the first bevel gear and the second bevel gear.

[0013] Specifically, the mounting ring is a magnetic mounting ring; the connecting ring is a magnetic connecting ring; and adjacent surfaces of the mounting ring and the connecting ring magnetically repel each other.

[0018] When the steel structure assembly positioning device provided by the utility model is used, the device is set up on the main body of the steel structure, and the part plate to be installed is placed between the clamping unit and the main body of the steel structure. The clamping unit is driven by the driving unit to perform a clamping action to achieve positioning and clamping of the parts, which is convenient for riveting and welding of the parts. After the riveting and welding is completed, the splint can be loosened by reversing the connecting shaft. The technical problem that the error is large when manually aligning smaller parts during riveting and welding is solved. Once the riveting and welding is completed, the parts are integrated with the main body of the steel structure, and the error is difficult to eliminate. In addition, long-term use of manual alignment requires workers to carry and the labor intensity is high.

[0019] In addition, the device also includes a second clamping mechanism and a first screw rod. When adjustment is required for part plates of different sizes, the first bevel gear of the connecting shaft is kept in mesh with the third bevel gear of the first screw rod, thereby driving the first screw rod to rotate around the X-axis.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0029] Reference Figure 1-2 The utility model provides a steel structure assembly positioning device, including a clamping unit and a driving unit; the driving unit includes a connecting shaft 4, a first screw rod 7 and a second screw rod 9; the two ends of the connecting shaft 4 are respectively sleeved with a first bevel gear 5 and a second bevel gear 6; the first screw rod 7 is fixedly sleeved with a third bevel gear 8 matching the first bevel gear 5; the first screw rod 7 rotates around the X axis under the drive of the first bevel gear 5; the second screw rod 9 is fixedly sleeved with a fourth bevel gear 10 matching the second bevel gear 6; the second screw rod 9 rotates around the Y axis under the drive of the second bevel gear 6;

[0030] The clamping unit includes a first clamping mechanism; the first clamping mechanism includes a first clamping member 11 and a second clamping member 12 respectively threadedly connected to two ends of the second screw rod 9, and the thread directions of the two ends of the second screw rod 9 are opposite;

[0031] The first clamping member 11 and the second clamping member 12 are slidably connected via a third sliding rod 17 ; the third sliding rod 17 is threadedly connected to the first screw rod 7 .

[0032] In actual use, the steel structure assembly positioning device is set up on the main body of the steel structure, the connecting shaft 4, the first screw rod 7 and the second screw rod 9 are located above the steel structure, and the first clamp 11 and the second clamp 12 are located on both sides of the steel structure. The parts to be welded are placed between the first clamp 11, the second clamp 12 and the main body of the steel structure. Press down the connecting shaft 4 to make the second bevel gear 6 mesh with the fourth bevel gear 10, rotate the connecting shaft 4, and drive the second screw rod 9 to rotate around the Y axis. Since the thread directions at both ends of the second screw rod 9 are opposite, the first clamp 11 and the second clamp 12 threadedly connected to the two ends of the second screw rod 9 are close to each other along the third slide bar 17 under the rotation of the second screw rod 9, clamping the parts and facilitating riveting. After the riveting is completed, rotate the connecting shaft 4 in the opposite direction to move the first clamp 11 and the second clamp 12 in opposite directions to release the parts. Move the steel structure assembly positioning device to the next work position.

[0033] Furthermore, the clamping unit also includes a second clamping mechanism; the second clamping mechanism includes a third clamping member 13 and a fourth clamping member 14; the first clamping member 11 and the fourth clamping member 14 are slidably connected via a first slide bar 15; the second clamping member 12 and the third clamping member 13 are slidably connected via a second slide bar 16; the first slide bar 15 and the second slide bar 16 are respectively threadedly connected at both ends of the second screw rod 9. During the rotation of the second screw rod 9 around the Y axis, the first slide bar 15 and the second slide bar 16 are driven to generate relative motion, thereby causing the first clamping member 11 and the second clamping member 12, and the third clamping member 13 and the fourth clamping member 14 to generate relative motion synchronously, perform a clamping action, and achieve stable clamping of parts.

[0034] In order to adapt to the clamping of parts of different sizes and improve the use range of the device, such as Figure 3 As shown, the third clamping member 13 and the fourth clamping member 14 are slidably connected by the fourth slide bar 18; the third slide bar 17 and the fourth slide bar 18 are respectively threadedly connected to the two ends of the first screw rod 7, and the thread directions of the two ends of the first screw rod 7 are opposite. When it is necessary to perform riveting welding on parts of different sizes, lift the connecting shaft 4 to make the first bevel gear 5 mesh with the third bevel gear 8, rotate the connecting shaft 4, and thus drive the third bevel gear 8 and the first screw rod 7 to rotate around the X axis. The first screw rod 7 drives the third slide bar 17 and the fourth slide bar 18 to produce relative movement through the thread, thereby causing the first clamping mechanism and the second clamping mechanism to produce relative movement, and adjust the clamping range to adapt to the size of the parts to be welded.

[0035] Furthermore, the steel structure assembly positioning device also includes a support frame 2; a mounting ring 3 is provided on the support frame 2; the connecting shaft 4 is movably connected in the mounting ring 3, and the mounting ring 3 is located between the first bevel gear 5 and the second bevel gear 6. When in use, the support frame 2 is placed on the steel structure body, and the connecting shaft 4 moves up and down relative to the mounting ring 3 to achieve the engagement or disengagement of the second bevel gear 6 and the fourth bevel gear 10.

[0036] Optional, such as Figure 4 As shown, the support frame 2 includes a first support frame 201 and a second support frame 202; the cross-sections of the first support frame 201 and the second support frame 202 are both inverted L-shaped; the tops of the first support frame 201 and the second support frame 202 are connected by a mounting ring 3.

[0037] In order to facilitate the operation of the connecting shaft 4 to move up and down or rotate, a connecting ring 401 is provided on the connecting shaft 4; the connecting ring 401 is located between the first bevel gear 5 and the second bevel gear 6. A rocker 402 is provided on the connecting ring 401. The number of rockers 402 is designed according to needs, and preferably four are arranged at equal intervals. When in use, the rocker 402 is pressed down to make the second bevel gear 6 mesh with the fourth bevel gear 10, and then the rocker 402 is rotated to drive the connecting shaft 4 to rotate, thereby rotating the second bevel gear 6.

[0038] Specifically, the mounting ring 3 is a magnetic mounting ring; the connecting ring 401 is a magnetic connecting ring; the adjacent surfaces of the mounting ring 3 and the connecting ring 401 magnetically repel each other. When not in use, due to the repulsive force between the connecting ring 401 and the mounting ring 3, the second bevel gear 6 and the fourth bevel gear 10 are disengaged. When it is necessary to clamp the parts, the rocker 402 is pressed down to overcome the repulsive force and make the second bevel gear 6 and the fourth bevel gear 10 mesh.

[0039] In a detailed implementation, the steel structure assembly positioning device further includes a bottom plate 1; the support frame 2 is fixed on the bottom plate 1. When in use, the bottom plate 1 is placed on the steel structure body to improve the stability of the device.

[0044] The driving unit includes a connecting shaft 4, a first screw rod 7 and a second screw rod 9; the upper and lower ends of the connecting shaft 4 are respectively sleeved with a first bevel gear 5 and a second bevel gear 6; a magnetic connecting ring is fixedly sleeved in the middle of the connecting shaft 4, and four rockers 402 are arranged at equal intervals along the circumferential direction of the connecting ring 401; the connecting shaft 4 is movably inserted in the mounting ring 3, the mounting ring 3 is located between the first bevel gear 5 and the second bevel gear 6, and the adjacent surfaces of the mounting ring 3 and the connecting ring 401 are magnetically repelled; the middle part of the first screw rod 7 is fixedly sleeved with a third bevel gear 8 matching the first bevel gear 5, and the first screw rod 7 rotates around the X-axis under the drive of the first bevel gear 5; the middle part of the second screw rod 9 is fixedly sleeved with a fourth bevel gear 10 matching the second bevel gear 6, and the second screw rod 9 rotates around the Y-axis under the drive of the second bevel gear 6.

[0045] The clamping unit includes a first clamping mechanism and a second clamping mechanism; the first clamping mechanism includes a first clamping member 11 and a second clamping member 12, and the second clamping mechanism includes a third clamping member 13 and a fourth clamping member 14; the first clamping member 11 and the fourth clamping member 14 are slidably connected via a first slide bar 15, the second clamping member 12 and the third clamping member 13 are slidably connected via a second slide bar 16, the first clamping member 11 and the second clamping member 12 are slidably connected via a third slide bar 17, and the third clamping member 13 and the fourth clamping member 14 are slidably connected via a fourth slide bar 18; the first slide bar 15 and the second slide bar 16 are respectively threadedly connected to both ends of the second screw rod 9, and the thread directions at both ends of the second screw rod 9 are opposite; the third slide bar 17 and the fourth slide bar 18 are respectively threadedly connected to both ends of the first screw rod 7, and the thread directions at both ends of the first screw rod 7 are opposite. The first clamping member 11, the second clamping member 12, the third clamping member 13 and the fourth clamping member 14 are all clamping plates, and are provided with a limit frame 19 on the outside and a limit hole on the top. The first slide bar 15 and the second slide bar 16 are slidably connected through their corresponding limit frames 19, and the third slide bar 17 and the fourth slide bar 18 are slidably connected through their corresponding limit holes, and the ends of the third slide bar 17 and the fourth slide bar 18 are provided with baffles 20 to prevent them from falling off from the limit holes.

[0046] When in use, the device is mounted on the main body of the steel structure, and the roller 21 is in contact with the surface of the main body of the steel structure. The driving unit is located above the steel structure, and the parts to be welded are placed between the clamping unit and the main body of the steel structure. Push the rocker 402 downward to overcome the repulsive force between the mounting ring 3 and the connecting ring 401, drive the connecting shaft 4 to move downward, and make the second bevel gear 6 and the fourth bevel gear 10 mesh with each other. Turn the rocker 402 to drive the connecting shaft 4 to rotate through the connecting ring 401, so that the second bevel gear 6 rotates, and the second bevel gear 6 drives the fourth bevel gear 10 to rotate through meshing, and the fourth bevel gear 10 drives the second screw 9 to rotate around the Y axis. Since the thread directions of the two ends of the second screw 9 are opposite, the first slide bar 15 and the second slide bar 16 threadedly connected at the two ends of the second screw 9 produce relative motion, thereby causing the first clamp 11 and the second clamp 12, the third clamp 13 and the fourth clamp 14 to synchronously produce relative motion, perform clamping action, clamp the parts, and facilitate riveting. After riveting and welding are completed, the rocker 402 is rotated in the opposite direction to release the components from the first clamping mechanism and the second clamping mechanism, and the steel structure assembly positioning device is moved to the next working position.

[0047] When it is necessary to adjust the parts plates of different sizes, the repulsive force of the mounting ring 3 and the connecting ring 401 keeps the first bevel gear 5 meshed with the third bevel gear 8, and the rocker 402 is rotated to drive the first bevel gear 5 to rotate, thereby driving the third bevel gear 8 and the first screw rod 7 to rotate around the X axis. The first screw rod 7 drives the third slide bar 17 and the fourth slide bar 18 to produce relative movement through the thread, thereby causing the first clamping mechanism and the second clamping mechanism to produce relative movement, and the clamping range is adjusted to adapt to the size of the parts to be welded.
