Description

Technical Field

[0001] This invention relates to the field of truss processing technology, and more specifically to a truss assembly and welding device. Background Technology

[0002] Truss structures, with their superior mechanical properties and high strength-to-weight ratio, are widely used in many fields such as architecture, bridges, stage equipment, and machinery support frames. Trusses are typically constructed from multiple members connected by welded joints, and their overall structural strength, precision, and stability largely depend on the quality of the welded joints.

[0003] Currently, truss welding largely relies on workers using handheld welding torches. This process not only demands extremely high skill levels from the welders, but also requires workers to constantly change positions and postures, resulting in immense labor intensity. Furthermore, limitations in workers' working hours and variations in their skill levels make it difficult to maintain a stable welding output.

[0004] To address this, we propose a truss assembly and welding device. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a truss assembly and welding device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a truss assembly and welding device, including a processing table, a frame sliding outside the processing table and a welding torch set inside the frame, including an installation mechanism, including installation blocks set above both ends of the processing table, a lead screw rotating inside the installation block with opposite thread directions at both ends, and a loading block 1 threaded onto the outer walls at both ends of the lead screw and sliding inside the installation block for supporting chord members, and multiple bearing mechanisms for supporting web members are provided between the two installation blocks. Through the operation of the installation mechanism, the chord members can be supported, and through the bearing mechanisms, the web members can be supported. The frame is equipped with an adjustment component for adjusting the position of the welding torch. The position of the welding torch can be adjusted by operating the adjustment component.

[0007] Furthermore, the adjustment assembly includes a connecting block disposed on one side of the welding torch for adjusting the angle of the welding torch and a linkage block fixed to the top of the connecting block for adjusting the corresponding position of the connecting block. The top of the linkage block is threaded with a screw for adjusting the corresponding position of the linkage block. The top of the linkage block abuts against a sliding plate that slides within the frame for adjusting the height of the linkage block. Multiple hydraulic cylinders with piston ends fixed on the sliding plate are fixed to the inner wall of the top of the frame for adjusting the height of the sliding plate. Through the operation of the above components, the height, position and angle of the welding torch can be adjusted.

[0008] Furthermore, one end of the screw is connected to a motor fixed to the bottom side of the slide plate for driving the screw to rotate, and the other end of the screw is rotatably connected to a connecting plate fixed to the bottom side of the slide plate. The operation of the motor can drive the screw to rotate.

[0009] Furthermore, the connecting block has an installation groove at the end away from the linkage block. A fixing block is hinged inside the installation groove and fixed to the welding gun. A drive plate is hinged to the outer side of the tail end of the welding gun. A transmission block that slides inside the connecting block is hinged to the movable end of the drive plate. Multiple pneumatic cylinders with piston ends fixed to the transmission block are fixed inside the connecting block for driving the transmission block to move. The transmission block can be driven to move by the operation of the pneumatic cylinders.

[0010] Furthermore, one side of the welding torch is provided with an air intake pipe for absorbing fumes. Multiple fixing sleeves fixed on the welding torch are movably sleeved on the outside of the air intake pipe to fix the position of the air intake pipe. Support legs are fixed at the four corners of the bottom side of the processing table to support the processing table. Fumes generated during welding processing can be extracted through the air intake pipe, and the processing table can be supported by the support legs.

[0011] Furthermore, the processing table has a sliding groove at both ends. A slider fixed to the inner wall of the frame for supporting the frame is slidably inserted into the sliding groove. A drive block sliding on the top side of the processing table is fixed to the inner wall at both ends of the frame. A screw rod is threaded through the drive block for moving the drive block. One end of the screw rod is connected to a motor fixed to the top side of the processing table for driving the screw rod to rotate. The other end of the screw rod is rotatably connected to a connecting plate fixed to the top side of the processing table. By running the motor, the screw rod rotates, which in turn moves the drive block, moves the frame, and moves the welding torch. At this time, the corresponding position of the welding torch can be adjusted.

[0012] Furthermore, at one end of the processing table, the bottom of the mounting block is fixed with two stabilizing blocks fixed to the processing table, and at the other end of the processing table, the bottom of the mounting block is fixed with two sliding blocks. The processing table has two sliding grooves, and the sliding blocks are fixed to the outside of the sliding blocks and slidably inserted into the adjacent sliding grooves. The sliding blocks are threaded with screws for moving the sliding blocks. One end of the screws is connected to a motor fixed to the adjacent stabilizing blocks for driving the screws to rotate. The other end of the screws is fixed with a stop to prevent the sliding blocks from detaching from the screws. By running the motor, the screws can be rotated, causing the sliding blocks to move and the mounting blocks on the sliding blocks to move. At this time, the distance between the two mounting blocks can be adjusted to meet the requirements of installing chords of different lengths.

[0013] Furthermore, the bearing mechanism includes two loading blocks symmetrically arranged and rotating on the top side of the processing table. A connecting column with its tail end extending below the processing table is fixed to the bottom of the two loading blocks for rotating the two loading blocks. A pushing block movably sleeved outside the connecting column is provided below the processing table. A gear for driving the connecting column to rotate is fixedly sleeved on the outer wall of the connecting column located below the processing table. A rack plate meshing with the gear and fixed on the inner wall of the pushing block is provided on the outer side of the gear for driving the gear to rotate. One end of the pushing block is fixed to a fixed plate on the bottom side of the processing table. Multiple pneumatic cylinders are fixed to the outer side of the fixed plate, with piston ends fixed to the pushing block for moving the pushing block. The operation of the pneumatic cylinders causes the pushing block to move, which in turn causes the rack plate to move, the gear to rotate, the connecting column to rotate, and the two loading blocks to rotate. This causes the web members on the two loading blocks to deflect, thereby facilitating the contact between the web members and the chord members according to the required length.

[0014] Furthermore, two adjacent rack plates are respectively fixed on the inner walls on both sides of the push block, and a support block for supporting the connecting column is fixed on the bottom side of the processing table. The end of the connecting column away from the processing table is rotatably connected to the support block. The support block can support the connecting column and improve its stability.

[0015] Furthermore, a guide hole is provided at the end of the push block away from the second pneumatic cylinder. A guide block, which is fixed to the bottom side of the processing table and is used to guide the displacement of the push block, is slidably inserted inside the guide hole. Through the sliding cooperation of the guide hole and the guide block, the push block can be supported and guided, thereby improving the stability of the push block.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention can assemble the chords and web members of a truss, and can perform welding processing on the chords and web members without requiring construction personnel to use welding guns, thus reducing the labor intensity of workers and improving welding efficiency and stability. It can be adaptively adjusted according to the length of the chords and web members, thereby performing welding processing on chords and web members of different lengths within a certain range, with a wide working range.

[0017] 2. This invention allows for flexible adjustment of the welding torch position according to welding requirements, adapting to welding scenarios of different types of trusses. It also reduces the impact of welding fumes on the surrounding environment and has high working performance. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Combination Figure 1This embodiment of a truss assembly and welding device includes a processing table 1, a frame 18 sliding outside the processing table 1, and a welding torch 2 disposed inside the frame 18. It includes: an installation mechanism comprising mounting blocks 3 disposed above both ends of the processing table 1, a lead screw 4 rotating inside the mounting blocks 3 with opposite thread directions at both ends, and a loading block 5 threaded onto the outer walls at both ends of the lead screw 4 and sliding inside the mounting blocks 3 for supporting chord members; multiple supporting mechanisms for supporting web members are provided between the two mounting blocks 3; and an adjustment component for adjusting the position of the welding torch 2 is provided on the frame 18.

[0022] The implementation principle of a truss assembly and welding device in this application embodiment is as follows: when it is necessary to assemble and weld the truss, the chord can be loaded inside the loading block 5, and the web member is loaded between the two chords through the bearing mechanism. Then, by adjusting the operation of the component, the welding gun 2 is moved to move, so that the output end of the welding gun 2 corresponds to the connection point of the chord and the web member. Through the operation of the welding gun 2, the web member is welded to the chord.

[0023] Example 2: Combination Figure 2 and Figure 7This embodiment, based on embodiment 1, further improves upon the following: the adjustment assembly includes a connecting block 23 disposed on one side of the welding torch 2 for adjusting the angle of the welding torch 2, and a linkage block 21 fixed to the top of the connecting block 23 for adjusting the corresponding position of the connecting block 23. A screw rod 22 for adjusting the corresponding position of the linkage block 21 is threaded through the top of the linkage block 21. The top of the linkage block 21 abuts against a sliding plate 19 that slides within the frame 18 for adjusting the height of the linkage block 21. Multiple hydraulic cylinders 20 with piston ends fixed to the sliding plate 19 are fixed to the inner wall of the top of the frame 18 for adjusting the height of the sliding plate 19. One end of the screw rod 22 is connected to a motor fixed to the bottom side of the sliding plate 19 for driving the screw rod 22 to rotate. The motor is a forward and reverse stepper motor. The other end of the screw rod 22 is rotatably connected to a connecting plate fixed to the bottom side of the sliding plate 19. A mounting groove is provided at the end of the connecting block 23 away from the linkage block 21, and a fixed fastener fixed to the welding torch 2 is hinged inside the mounting groove. Block 24, a drive plate 25 is hinged to the outer side of the tail end of the welding torch 2, and a transmission block 26 sliding in the connecting block 23 is hinged to the movable end of the drive plate 25. Multiple pneumatic cylinders 27 with piston ends fixed on the inner side of the connecting block 23 are used to drive the transmission block 26 to move. The operation of the motor can drive the screw 22 to rotate, drive the linkage block 21 to move, and drive the connecting block 23 and the welding torch 2 to move. When the welding torch 2 moves to above the connection point of the chord and the web, the operation of the hydraulic cylinder 20 can drive the slide plate 19 to move vertically, and drive the screw 22, linkage block 21, connecting block 23 and the welding torch 2 to move vertically. At this time, the welding torch 2 can be used to weld the connection point of the chord and the web. The operation of the pneumatic cylinder 27 can drive the transmission block 26 to move vertically, drive the drive plate 25 to deflect, and drive the welding torch 2 to deflect. At this time, the angle of the welding torch 2 can be adjusted according to the welding requirements.

[0024] Example 3: Combination Figure 6 This embodiment is further improved on the basis of embodiment 1 as follows: a suction pipe 28 for absorbing fumes is provided on one side of the welding torch 2.

Support legs 17 for supporting the processing table 1 are fixed at the four corners of the bottom side of the processing table 1. The suction pipe 28 is a soft pipe. When the welding torch 2 performs welding processing on the connection point of the chord and the web, the tail end of the suction pipe 28 can be connected to the suction pump. By running the suction pump, the suction pipe 28 is driven to extract the fumes generated during the welding processing. The processing table 1 can be supported by the support legs 17.

[0025] Example 4: Combination Figure 3This embodiment is an improvement on embodiment 1, with the following improvements: A sliding groove is provided at both ends of the processing table 1.

The other end of the screw 31 is rotatably connected to a connecting plate 2 fixed to the top side of the processing table 1. Through the operation of the motor 2, the screw 31 is driven to rotate, which drives the drive block 30 to move, which drives the frame 18 to move, and which drives the welding torch 2 to move. At this time, the corresponding position of the welding torch 2 can be adjusted.

The other end of the screw 3 9 has a stop block fixed to prevent the sliding block 8 from dislodging from the outside of the screw 3 9. By running the motor 3, the screw 3 9 can be driven to rotate, which drives the sliding block 8 to move and the mounting block 3 on the sliding block 8 to move. At this time, the distance between the two mounting blocks 3 can be adjusted to meet the needs of installing chords of different lengths.
