[0011] Preferably, a rotating gear is installed on the outside of the motor output shaft, and mounting grooves are opened at both ends and both sides of the bottom of the workbench. A screw rod is installed inside the mounting groove, and a connecting gear is installed at the bottom end of the screw rod. A mounting bracket is installed at the bottom end of the connecting gear, and the top of the mounting bracket is fixed to the bottom end of the workbench.

[0012] Preferably, a wire sleeve is installed on the outside of the screw rod, a connecting block is installed on one side of the wire sleeve, a movable cavity is opened inside the workbench on one side of the installation groove, a limiting block is installed inside the movable cavity, a first rubber pad is installed on one side of the limiting block, and one end of the connecting block is fixed to one side of the limiting block.

[0013] Preferably, a guide hole is opened inside the connecting block, a guide rod is installed inside the guide hole, the top end of the guide rod is fixed to the top end of the installation groove, and a guiding connection is formed between the guide rod and the connecting block.

[0015] Preferably, two groups of the limit blocks are provided, and the two groups of limit blocks are symmetrically distributed on the top end of the fixing frame.

[0016] Preferably, a guide structure is provided at the bottom end of the positioning clamping block, and the guide structure includes a guide seat, which is fixed to the top end of the fixing frame at the bottom end of the positioning clamping block. A guide groove is provided inside the guide seat, and a guide block is installed inside the guide groove.

[0017] Preferably, the top end of the guide block is connected to the bottom end of the positioning clamping block, and a guide connection is formed between the guide block and the guide seat.

[0018] The welding tool for machining a steel structure boiler lifting platform provided by the present invention has the following advantages:

[0019] Through the design of the positioning frame, when welding the U-shaped square tube steel structure, the position of the square tube can be positioned so that a preliminary U-shaped square tube can be formed inside the positioning frame after placement, making it more convenient for subsequent welding.

[0020] Furthermore, during positioning, by using the rotating bar and the moving seat in conjunction, when positioning and clamping the U-shaped square tube steel structure, a positioning clamp can be performed on its four corners at the same time to complete the preliminary positioning and clamping work. This clamping method can keep the U-shaped square tube steel structure in a precise position during welding, ensure the consistency and stability of the welding part, firmly fix the U-shaped square tube steel structure, and avoid position deviation due to external forces such as vibration and thermal deformation during welding;

[0021] Furthermore, the forward and reverse rotation of the motor can control the clamping or non-clamping of the positioning clamping block to achieve rapid clamping and positioning. Compared with traditional manual alignment and temporary fixation, it can greatly shorten the preparation time, reduce the difficulty and time cost of manual operation, make the square tube more conducive to welding operation, enable stable welding, make the weld better, reduce process defects such as porosity, slag inclusion, and incomplete penetration, improve the strength and reliability of the weld joint, and ensure the service life and performance of the welded structure;

[0022] Furthermore, when the positioning clamping block is clamping and positioning, the use of the second rubber pad can avoid direct rigid contact between the positioning clamping block and the square tube, and prevent damage to the surface of the square tube due to excessive clamping force or high hardness of the positioning clamping block, such as scratches, dents, deformation, etc. The rough surface of the second rubber pad can increase the friction with the square tube, making the clamping more stable, reducing the risk of the square tube sliding and displacement due to external forces during processing such as welding, improving the reliability of clamping, and ensuring processing accuracy;

[0023] Furthermore, when the positioning clamping block is clamping, the screw rod is driven to rotate by the cooperation of the rotating gear and the connecting gear. As the screw rod and the thread sleeve cooperate, one side of the limit block can be pressed against the four edges inside the U-shaped square tube steel structure, and then cooperate with the clamping of the four corners of the positioning clamping block to achieve multi-directional synchronous clamping of the U-shaped square tube steel structure without manual operation, making it more convenient to clamp, position and fix, and making the U-shaped square tube steel structure more stable during subsequent welding, and the effect is also better.

[0044] Reference Figures 1-16As shown: When processing the steel structure boiler lifting platform, the square tube that needs to be processed into the U-shaped steel structure is cut into the required length in advance. After the processing is completed, the square tube is placed on one side of the inside of the positioning frame 6. At this time, the positioning frame 6 can be used to locate the position where the square tube is placed, so that after the placement is completed, a preliminary U-shaped can be formed inside the positioning frame 6, making it more convenient in subsequent welding.

[0045] When the square tube is placed, the external power supply starts the motor 8. After starting, the motor 8 will drive the rotating disk 504 to rotate. When the rotating disk 504 rotates, it will drive the rotating bar 503. When the rotating bar 503 rotates, it cooperates with the teeth matching the bottom end of the moving seat 506, so that the moving seat 506 moves to one side under the guidance of the moving groove 502. When the moving seat 506 moves to one side, it will push the positioning clamping block 505 to move to one side as well, so that the positioning clamping block 505 rests on the connection of the mouth-shaped square tube steel structure. When the positioning clamping block 505 moves to one side, it will drive the guide block 402 to slide inside the guide groove 403, thereby guiding the positioning clamping block 505 so that the positioning clamping block 505 will not be offset in the process of moving and positioning, thereby completing the guide Towards the working direction, by using the four sets of positioning clamping blocks 505, a positioning clamp can be performed on the four corners of the U-shaped steel structure at the same time to complete the preliminary positioning clamping work, so that the U-shaped square tube steel structure is in a precise position during welding, ensuring the consistency and stability of the welding part, firmly fixing the U-shaped square tube steel structure, avoiding position deviation due to external forces such as vibration and thermal deformation during welding, thereby achieving rapid clamping and positioning. Compared with traditional manual alignment and temporary fixation, it can greatly shorten the preparation time, reduce the difficulty and time cost of manual operation, and put the square tube in a posture that is more conducive to welding operation. The welder or welding equipment can weld more conveniently and stably, making the weld better shaped, reducing process defects such as porosity, slag inclusion, and incomplete welding, improving the strength and reliability of the weld joint, and ensuring the service life and performance of the welded structure;

[0046] Furthermore, when clamping and positioning, the use of the second rubber pad 5020 can avoid direct rigid contact between the limit block 5019 and the square tube, preventing damage to the surface of the square tube due to excessive clamping force or high hardness of the limit block 5019, such as scratches, dents, deformation, etc. The rough surface of the second rubber pad 5020 can increase the friction with the square tube, making the clamping more stable, reducing the risk of the square tube sliding and displacing under external forces during processing such as welding, improving the reliability of clamping, ensuring processing accuracy, and effectively preventing the square tube from moving in the scenario where the position of the square tube is fixed during welding. The elasticity of the rubber plays a buffering role during clamping, absorbing and dispersing the impact force and vibration during the clamping process;

[0047] When the motor 8 is started and drives the rotating disk 504 to rotate, it also drives the rotating gear 508 to rotate. During the rotation process, the rotating gear 508 drives the connecting gear 5010 to rotate through the engagement with the connecting gear 5010. During the rotation process, the connecting gear 5010 drives the screw rod 5012 to rotate. During the rotation process, the screw rod 5012 drives the silk sleeve 5013 to rotate. During the rotation process, the silk sleeve 5013 is guided by the cooperation of the guide rod 5011 and the guide hole 5015, so that the silk sleeve 5013 is rotated on the screw rod 5012. The outer side of the U-shaped square tube moves upward, and the screw rod 5012 can drive the limit block 5019 to move upward inside the movable cavity 5017 through the connecting block 5014 during the upward movement, so that one side of the limit block 5019 is fitted against one side of the square tube, thereby realizing the clamping of both sides of the U-shaped square tube steel structure. By simultaneously performing a positioning clamping on the four sides and four corners of the U-shaped square tube steel structure, the U-shaped square tube steel structure is more stable during welding after positioning and clamping, and is not prone to position deviation, and the welding effect is better, thereby completing the positioning and clamping work of the U-shaped square tube steel structure.
