Description

Technical Field

[0001] This invention relates to a steel structure tooling fixture, and more particularly to a steel structure welding and forming arrangement fixing fixture. Background Technology

[0002] In the field of large steel structure manufacturing, welding is a crucial step in ensuring structural strength and stability. To guarantee welding quality, steel components must be precisely shaped and arranged in advance. Through reasonable spatial positioning, each component forms a geometric configuration that meets design requirements, laying the foundation for subsequent welding operations.

[0003] Currently, steel structure welding fixtures generally use traditional bolt fixing methods to achieve temporary constraints between components through mechanical connections. However, for complex steel structures with polyhedral features or requiring multiple welding passes, traditional fixtures reveal significant drawbacks in the process flow: every time the welding position changes or the number of welding layers increases, the fixture must be manually disassembled and reinstalled. Frequent mechanical operations not only consume a lot of labor costs, but also the cumulative positioning deviations caused by repeated clamping may affect the welding accuracy of components and the overall structural performance.

[0004] Therefore, there is an urgent need to design a fixing clamp that can fix the steel structure in a shaped arrangement to achieve the effect of stable fixation of the steel structure. Summary of the Invention

[0005] In order to overcome the shortcomings of existing steel structure welding fixtures that use conventional bolt fixing methods and require repeated disassembly and assembly in multiple welding operations, which consumes a lot of manpower, the purpose of this invention is to provide a steel structure welding forming and fixing fixture.

[0006] The technical solution is as follows: A steel structure welded and formed arrangement and fixing fixture includes a base, welding areas on both sides of the base, and a vertically arranged partition separating the base and the welding areas. Two first electric push rods are arranged at the bottom of each partition. The movable rods of the first electric push rods are connected to a support frame, which is located within the welding area. The fixture also includes a clamping mechanism disposed within the support frame. The clamping mechanism includes a dual-axis motor, a first screw, a slider, a clamping block, a return spring, and a diagonal guide rod. The dual-axis motor is located in the middle of the inner cavity of the support frame. The output shaft of the dual-axis motor is connected to the first screw via a coupling. Two sliders with opposite sliding directions are slidably disposed within the support frame. The first screw is threaded through the sliders, and the clamping block is slidably disposed through the sliders. A return spring connects the clamping block and the sliders. A diagonal guide rod is provided on the inner side of the support frame, and the diagonal guide rod makes frictional contact with the clamping block. The inclined guide rod can push the clamping block to slide relative to the slider. The dual-axis motor drives the first screw to rotate, and the first screw drives the slider to move in the opposite direction. Under the guidance of the inclined guide rod, the clamping block moves upward. The upper end face of the support frame has a reserved groove for the clamping block to move. The clamping block moves upward and moves in the opposite direction at the same time. The clamping block will laterally clamp and fix the steel component located on the support frame. The limiting post is fixed to the middle of the base. A lifting platform is slidably connected to the limiting post. A second electric push rod for driving the lifting platform to rise and fall is set at the upper end of the limiting post. The lifting platform is symmetrically connected to the limiting pressure rod by bolts. The limiting pressure rod is located above the support frame. The model of the limiting pressure rod can be changed in time according to the actual steel component to be welded. The base is symmetrically fixed with concave and convex butt blocks. This device can be arranged and combined horizontally to increase the welding line length of the steel component. Therefore, concave and convex butt blocks are provided.

[0007] Furthermore, anti-slip grooves are provided on the surface of the support frame.

[0008] Furthermore, it also includes symmetrically arranged detection mechanisms on the top of the base. The detection mechanisms are arranged in two symmetrical groups, totaling four. Each detection mechanism includes a rotating base, a telescopic arm, and an infrared sensor. The rotating base is fixed to the base, and the telescopic arm is rotatably connected to the rotating base. Damping is provided at the rotatable connection between the telescopic arm and the rotating base. The infrared sensor is located at the end of the telescopic arm. When not in use, the infrared sensor can be rotated to the inside of the base via the telescopic arm. The infrared sensor specifically includes an infrared transmitter and an infrared receiver. The infrared transmitter is located on the two rear telescopic arms, and the infrared receiver is located on the two front telescopic arms. The infrared receiver receives signals from the left and right sides. The infrared light emitted by the infrared emitter on the same side in the direction of the infrared beam is controlled by a cylinder inside the telescopic arm. After the telescopic arm is rotated to both sides of the welding area, the length of the telescopic arm is adjusted according to the width of the batch of steel components to be welded on the support frame. A controller is installed on the base. The controller is existing technology and is not shown in the figure. The infrared receiver of the infrared sensor and the dual-axis motor are electrically connected to the controller. When the steel component is introduced into the support frame, the steel component blocks the infrared light emitted by the infrared emitter. The infrared receiver no longer receives the infrared light and sends an electrical signal to the controller. The controller controls the operation of the dual-axis motor.

[0009] Furthermore, it also includes a movable clamping plate, a connecting block, and a second screw. The connecting block is slidably connected to the limiting pressure rod, and the movable clamping plate is fixedly connected to the end of the connecting block. The second screw is rotatably connected to the limiting pressure rod and is threaded through the connecting block. The end of the limiting pressure rod is bent downward to form a clamping part. The movable clamping plate is used to cooperate with the clamping part of the limiting pressure rod to fix the steel component. The second electric push rod drives the lifting platform to move down, and the limiting pressure rod will press down and fix the steel component in the support frame along with the lifting platform. At the same time, rotating the second screw drives the connecting block to move horizontally, and the movable clamping plate at the end of the connecting block will cooperate with the limiting pressure rod to clamp the upper end of the steel component.

[0010] Furthermore, it also includes a main water pipe, branch water pipes, and atomizing nozzles. The main water pipe is fixed to the bottom of the base, and the atomizing nozzles are installed on the partition plate with their openings facing the welding area. The main water pipe and the atomizing nozzles are connected through branch water pipes. An external water source can be connected to the main water pipe, and the water source is sprayed out from the atomizing nozzles through the branch water pipes.

[0011] Furthermore, it also includes a first pair of connecting ports and a second pair of connecting ports, with the first pair of connecting ports and the second pair of connecting ports respectively installed at both ends of the main water pipe.

[0012] Furthermore, it also includes an auxiliary guide plate, which is located on the side of the welding area away from the base, and the auxiliary guide plate is a wedge-shaped block.

[0013] The beneficial effects are as follows: This device is designed to be arranged and combined in real time according to the specifications and length of the steel components. After the steel components are placed on the support frame, the first screw is rotated by starting the dual-axis motor. The first screw drives the slider to move in opposite directions. The clamping block inside the slider moves upward under the guidance of the inclined guide rod. The clamping block clamps and fixes the steel components on both sides. Compared with the existing method of fixing with bolts, this device adopts automated clamping and fixing, which optimizes the cumbersome disassembly and assembly method of traditional tooling, improves fixing efficiency, and thus improves the welding efficiency of steel components.

Detailed Implementation

[0026] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Example: A steel structure welded and formed fixed clamp, such as Figures 1-11As shown, the system includes a base 1, a partition 101, a support frame 3, and a first electric push rod 4. Welding areas 2 are provided on both sides of the base 1. An auxiliary guide plate 31 is located on the side of the welding area 2 away from the base 1. The auxiliary guide plate 31 is a wedge-shaped block, facilitating the insertion and removal of steel components from the support frame 3 by workers. The base 1 and the welding area 2 are separated by two vertically arranged partitions 101. Two first electric push rods 4 are located at the bottom of the partitions 101. The movable rods of the first electric push rods 4 are connected to the support frame 3. Anti-slip grooves 301 are provided on the surface of the support frame 3 to increase the friction between the steel components and the support frame 3. The friction coefficient between the components allows the steel components to be placed more stably on the support frame 3. The support frame 3 is located in the welding area 2, which is equipped with a receiving groove. The support frame 3 is moved down into the receiving groove by the first electric push rod 4. At this time, the upper end of the support frame 3 is flush with the upper end of the auxiliary guide plate 31. The worker guides the steel component into the support frame 3 through the wedge-shaped auxiliary guide plate 31. The support frame 3 also includes a clamping mechanism 5, which includes a dual-axis motor 6, a first screw 7, a slider 8, a clamping block 9, a return spring 10, and an inclined guide rod 11. The dual-axis motor 6 is located in the middle of the inner cavity of the support frame 3. The output shaft of the dual-axis motor 6 is connected to two first screws 7 via a coupling. Two sliders 8 with opposite sliding directions are slidably disposed within the support frame 3. The first screws 7 are threaded onto the sliders 8, and the clamping block 9 is slidably disposed onto the sliders 8. A return spring 10 connects the clamping block 9 and the sliders 8. An inclined guide rod 11 is disposed on the inner side of the support frame 3. The inclined guide rod 11 makes frictional contact with the clamping block 9, and the inclined guide rod 11 can push the clamping block 9 to slide relative to the sliders 8. The dual-axis motor 6 drives the first screws 7 to rotate, and the first screws 7 cause the sliders 8 to move in opposite directions. The clamping block 9 is guided by the inclined guide rod 11. Under the action of the support frame 3, the upper end face of the support frame 3 has a reserved groove 302 for the clamping block 9 to move. The clamping block 9 moves upward and moves towards the opposite side at the same time. The clamping block 9 will laterally clamp and fix the steel component located on the support frame 3. The limiting post 16 is fixed to the middle of the base 1. The lifting platform 17 is slidably connected to the limiting post 16. The upper end of the limiting post 16 is provided with a second electric push rod 19 for driving the lifting platform 17 to rise and fall. The lifting platform 17 is symmetrically connected to the limiting pressure rod 18 by bolts. The limiting pressure rod 18 is located above the support frame 3. The model of the limiting pressure rod 18 can be replaced in time according to the actual steel component to be welded. Figure 7 For example, the limiting pressure bar 18 adopts a horizontal L-shape, which is suitable for square or flat steel components. The replaceable limiting pressure bar 18 can improve the applicability of fixing different steel components. The base 1 is symmetrically fixed with concave butt joint block 29 and convex butt joint block 30. This device can be arranged and combined horizontally to increase the welding line length of the steel components. Therefore, concave butt joint block 29 and convex butt joint block 30 are provided. After the concave butt joint block 29 and convex butt joint block 30 are connected to each other, the adjacent bases 1 will not shift, thereby improving the stability of welding.

[0028] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes detection mechanisms 12 symmetrically arranged on the top of the base 1. The detection mechanisms 12 are arranged in two symmetrical groups, totaling four. Each detection mechanism 12 includes a rotating base 13, a telescopic arm 14, and an infrared sensor 15. The rotating base 13 is fixed to the base 1, and the telescopic arm 14 is rotatably connected to the rotating base 13. Damping is provided at the rotatable connection between the telescopic arm 14 and the rotating base 13. The infrared sensor 15 is located at the end of the telescopic arm 14. When idle, the infrared sensor 15 can be rotated to the inside of the base 1 via the telescopic arm 14. The infrared sensor specifically includes an infrared transmitter and an infrared receiver. The infrared transmitter is located on the two rear telescopic arms 14, and the infrared receiver is located on the two front telescopic arms 14. The infrared receiver receives infrared light emitted by the infrared emitter on the same side in the left and right directions. The telescopic arm 14 is equipped with a cylinder, which controls the expansion and contraction of the telescopic arm 14. After the telescopic arm 14 is rotated to both sides of the welding area 2, the length of the telescopic arm 14 is adjusted according to the width of the batch of steel components to be welded on the support frame 3. A controller is installed on the base 1. The controller is existing technology and is not shown in the figure. The infrared receiver of the infrared sensor and the dual-axis motor 6 are electrically connected to the controller. When the steel component is introduced into the support frame 3, the steel component blocks the infrared light emitted by the infrared emitter, and the infrared receiver no longer receives infrared light. The infrared receiver sends an electrical signal to the controller, and the controller controls the operation of the dual-axis motor 6.

[0029] like Figure 1 and Figure 8 As shown, it also includes a movable clamping plate 21, a connecting block 22, and a second screw 23. The connecting block 22 is slidably connected to the limiting pressure rod 18. The connecting block 22 is L-shaped, and the movable clamping plate 21 is fixed to the right end of the L-shaped long rod of the connecting block 22. The second screw 23 is rotatably connected to the limiting pressure rod 18. The second screw 23 is threaded through the connecting block 22. The end of the limiting pressure rod 18 is bent downward to form a clamping part. The movable clamping plate 21 is used to cooperate with the clamping part of the limiting pressure rod 18 to fix the steel component. Specifically, the second electric push rod 19 drives the lifting platform 17 to move down, and the limiting pressure rod 18 will press down and fix the steel component in the support frame 3 along with the lifting platform 17. At the same time, the second screw 23 is rotated to drive the connecting block 22 to move horizontally (the driving force of the second screw 23 can be realized by a motor). The movable clamping plate 21 at the end of the connecting block 22 will cooperate with the limiting pressure rod 18 to clamp the upper end of the steel component, thereby improving the fixing effect of the steel component.

[0030] like Figure 1 and Figure 9As shown, it also includes a main water pipe 24, a branch water pipe 25, and an atomizing nozzle 26. The main water pipe 24 is fixed to the bottom of the base 1, and the atomizing nozzle 26 is installed on the partition plate 101. The opening of the atomizing nozzle 26 faces the welding area 2. The main water pipe 24 and the atomizing nozzle 26 are connected through the branch water pipe 25. An external water source can be connected to the main water pipe 24, and the water source is sprayed out from the atomizing nozzle 26 through the branch water pipe 25. The atomizing nozzle 26 is used to cool and shape the welded steel components, thereby improving the efficiency of re-welding the steel components.

[0031] like Figure 1 and Figure 10 As shown, it also includes a first pair of connecting ports 27 and a second pair of connecting ports 28. The main water pipe 24 is provided with a first pair of connecting ports 27 and a second pair of connecting ports 28 at both ends. An elastic buffer is connected between the first pair of connecting ports 27 and the main water pipe 24. In this embodiment, the elastic buffer is a corrugated pipe. This device can be arranged and combined horizontally to increase the welding line length of the steel components. Therefore, a first pair of connecting ports 27 and a second pair of connecting ports 28 that can be tightly connected are provided.

[0032] This device adopts a horizontal arrangement and combination form. Adjacent bases 1 are joined together by concave butt joint blocks 29 and convex butt joint blocks 30. This allows for real-time adjustment of the welding line length according to the specifications and length of the steel components. Taking a single device as an example, the welding area 2 is equipped with a receiving groove. The first electric push rod 4 drives the support frame 3 to move down into the receiving groove. At this time, the upper end of the support frame 3 is flush with the upper end of the auxiliary guide plate 31. The operator guides the steel component into the support frame 3 through the wedge-shaped auxiliary guide plate 31. Then, the first electric push rod 4 is activated again to move the support frame 3 up to the appropriate welding position for inspection. After the infrared sensor 15 of mechanism 12 detects the steel component, the steel component blocks the infrared light emitted by the infrared emitter, and the infrared receiver no longer receives the infrared light. The infrared receiver sends an electrical signal to the controller, which controls the dual-axis motor 6 to operate. The infrared sensor 15 starts the dual-axis motor 6, which drives the first screw 7 to rotate. The first screw 7 drives the slider 8 to move in opposite directions through the thread. At the same time, the clamping block 9, which is slidably connected to the slider 8, moves upward under the guidance of the inclined guide rod 11. The return spring 10 is compressed. Then, the clamping block 9 moves upward while moving in opposite directions. After the holding block 9 extends out of the support frame 3, it will clamp and fix the steel component on both sides. The second electric push rod 19 drives the lifting platform 17 to move down, and the limiting pressure rod 18 will press down and fix the steel component in the support frame 3 along with the lifting platform 17. At the same time, the second screw 23 is rotated to drive the connecting block 22 to move horizontally (the driving force of the second screw 23 can be achieved by a motor). The movable clamping plate 21 at the end of the connecting block 22 will cooperate with the limiting pressure rod 18 to clamp the upper end of the steel component, thereby improving the fixing effect of the steel component. The steel component is fixed by the holding block 9, the limiting pressure rod 18 and the movable clamping plate 21. After the components are fixed, the steel components can be welded using existing welding equipment. An external water source can be connected to the main water pipe 24, and the water source is sprayed out through the branch water pipe 25 by the atomizing nozzle 26. The atomizing nozzle 26 is used to cool and shape the welded steel components, improving the efficiency of welding the steel components again. After welding is completed, the second electric push rod 19 drives the lifting platform 17 to move upward, the dual-axis motor 6 operates in the opposite direction, and the clamping block 9 will move backward, thereby releasing the clamping and fixing effect on the steel components. The staff can adjust the subsequent welding position of the steel components and then perform the above fixing actions.
