Description

Technical Field

[0001] The present invention relates to the technical field of welding processing equipment, in particular to a steel structure processing welding device. Background Art

[0002] The patent application, with application publication number CN116690052B, includes a mounting platform, a moving assembly, a lifting assembly, an adjustment assembly, a steering assembly, a welding device, a screw slide, a flip assembly, a fixed assembly, and a suction assembly. The moving assembly comprises two sets of moving assemblies, one mounted on either side of the mounting platform.

The fixed assemblies comprise two sets of two fixed assemblies, each mounted on a flip assembly. The suction assembly is fixedly mounted on the moving assembly. Advantages include a high degree of automation in the loading mechanism. During loading, the same type of vertical plate material can be loaded simultaneously on both sides, saving time. After loading is completed, the entire steel structure is aligned, eliminating the need for repeated adjustments, making it very convenient.

[0003] In the prior art including the above-mentioned patents, steel welding is divided into intelligent robotic arm welding and manual or vertical welding machine welding head, adjusting the angle just to ensure the integrity of the welding. In reality, manual welding or welding machine welding are mostly used. The latter two have the following problems during welding: manual welding, when welding long lengths of steel, it is necessary to maintain a long welding posture, which will affect the welding integrity in the later stage and require a rest in the middle, which is very inefficient. New operators are prone to welding angle errors. When the welding machine is used for vertical welding, the steel needs to be adjusted to the best welding angle. When the number of steels is large and different steels need to be replaced during welding, it will also cause welding efficiency and large errors in welding angles. Summary of the Invention

[0004] The problem to be solved by the present invention is that when manually welding steels at different angles, the welding angle of the welding head needs to be manually adjusted according to the angle requirements, and the same posture cannot be maintained for a long time.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a steel structure processing welding device, comprising a welding assembly, a welding gun is provided at the bottom of the welding assembly, and a welding structure is provided at the bottom of the welding gun; The welding structure includes a welding head and a storage rack, a driving wheel is rotatably provided at the bottom of the storage rack, and two rotating rods are provided at the bottom of the driving wheel, the top of one of the rotating rods is fixedly connected to the bottom of the driving wheel, the two rotating rods are parallel and juxtaposed, and a shell is fixedly provided at the bottom of the two rotating rods, a slot is provided at the top of one side of the rotating rod, a latch is passed through the front of the slot, and a connecting plate is provided at the top of one side of the other rotating rod, the connecting plate is adapted to the slot and can be fixed by a latch, and sliders are movably provided at the bottom of the two shells.

[0006] Preferably, auxiliary wheels are provided on both sides of the shell, and three cavities are opened inside the shell, and sliding grooves are opened on both sides of the inner wall of one of the cavities. The slider is adapted to the sliding groove, and the groove depth of the sliding groove is greater than the sliding connection on the slider. The slider can move up and down and tilt left and right in the sliding groove.

[0007] Preferably, movable wheels are rotatably provided on both sides of the slider, springs are fixedly provided on the tops of both sides of the movable wheels, and the tops of the springs are fixedly connected to the tops of the inner walls of the shell.

[0008] Preferably, a driven wheel is fixedly provided on one side of the welding head, and the other side of the driven wheel is rotatably connected to the welding gun.

[0009] Preferably, a fixing frame is fixedly provided at the bottom of the welding gun, and an engaging wheel is rotatably provided at the bottom of the fixing frame, and the engaging wheel is engaged with the driven wheel and the driving wheel.

[0010] Preferably, a positioning rod is provided on the top of the welding gun, and a fixing wheel set is provided on the top of the positioning rod.

[0011] Preferably, a table frame is provided at the bottom of the table top, slide rails are provided on both sides of the top of the table top, and a control frame is provided on the top of the slide rails.

[0012] Preferably, the front of the control frame is fixedly connected to the back of the welding assembly, and the top of the desktop is provided with a plurality of positioning plates arranged in a straight line.

[0013] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) A welding structure is provided at the bottom of the welding gun. The welding structure can control the welding head through the fixed wheel group and the movable wheel to adjust the angle adaptively when welding steels at different angles, so that the welding head is always at a better welding angle to ensure the welding quality of the steel. The fixed wheel group and the positioning plate cooperate to ensure that one side of the steel to be welded is always vertical. At this time, the movable wheel will be adaptively adjusted according to the offset angle of the steel on the other side, controlling the rotation of the smallest driving wheel. The driving wheel cooperates with the meshing wheel to drive the driven wheel to rotate. The driven wheel drives the welding head to rotate at an angle so that it is aligned with the welding point of the steel at a better welding angle. In this way, when welding steel, the operator only needs to hold one side of the steel with his hand and pull it slowly to weld. There is no need to manually adjust and align the angle. The gear ratios of the driving wheel, meshing wheel and driven wheel are all debugged in advance. (2) The shell and the movable wheel cooperate with each other. When encountering steel with angle deviation, when one of the movable wheels is pressed, it will drive the rotating rod to rotate, so that the shell can automatically adapt to the angle. The two movable wheels are connected by a slider in the middle. The slider can move up and down and tilt left and right inside the shell, so that the entire shell can achieve adaptive adjustment of the angle. Two shells are designed in the present invention, one of which is at a certain distance from the welding head position. This distance is the distance used for adjusting the welding head. When the shell cooperates with the movable wheel to adapt to the angle change, the welding head will also rotate and start welding. The distance left in the middle is just enough for the welding head to adjust. The two shells are fixed by a connecting plate and a pin. When not in use, one of the shells can be completely disassembled without affecting the folding and storage of the other shell. The disassembly method is simple and convenient and will not take up too much operator time. (3) The function of the positioning wheel is to determine the vertical plane of the steel, so that the movable wheel behind it can adapt to the angle to adjust the welding direction of the welding head. In addition, the positioning wheel and the movable wheel can be rotated and folded, so that the user can freely change the welding method of the welding head according to different usage scenarios, and it is convenient for workers to switch between manual adjustment, adaptive and vertical welding at will. There is no need to use sensors or other methods. The angle can be adjusted in a time-consuming way that is close to zero. The operator can stay away from the welding arc, smoke and high temperature areas and work in a safer position. BRIEF DESCRIPTION OF THE DRAWINGS

The top of one rotating rod 403 is fixedly connected to the bottom of the driving wheel 409. The two rotating rods 403 are parallel and juxtaposed. The bottoms of the two rotating rods 403 are fixedly provided with a shell 402. A slot is provided at the top of one side of the rotating rod 403, and a pin 414 is provided through the front of the slot. A connecting plate 410 is provided at the top of one side of the other rotating rod 403. The connecting plate 410 is adapted to the slot and can be fixed by the pin 414. Sliders 415 are movably provided at the bottoms of the two shells 402.

[0019] Auxiliary wheels 411 are provided on both sides of the shell 402, and three cavities are opened inside the shell 402. Both sides of the inner wall of one of the cavities are provided with sliding grooves, and the slider 415 is adapted to the sliding groove. The groove depth of the sliding groove is greater than the sliding connection on the slider 415. The slider 415 can move up and down and tilt left and right in the sliding groove.

[0020] Movable wheels 406 are rotatably provided on both sides of the slider 415 . Springs 416 are fixedly provided on the tops of both sides of the movable wheels 406 . The tops of the springs 416 are fixedly connected to the top of the inner wall of the housing 402 .

[0021] A driven wheel 407 is fixedly provided on one side of the welding head 401 , and the other side of the driven wheel 407 is rotatably connected to the welding gun 3 .

[0022] A fixing frame 412 is fixedly provided at the bottom of the welding gun 3 , and an engaging wheel 408 is rotatably provided at the bottom of the fixing frame 412 . The engaging wheel 408 is engaged with the driven wheel 407 and the driving wheel 409 .

[0023] A positioning rod 404 is provided on the top of the welding gun 3 , and a fixing wheel set 405 is provided on the top of the positioning rod 404 .

[0024] A table frame 8 is provided at the bottom of the table top 7 , slide rails 5 are provided on both sides of the top of the table top 7 , and a control frame 1 is provided on the top of the slide rails 5 .

[0025] The front of the control frame 1 is fixedly connected to the back of the welding assembly 2, and a plurality of positioning plates 6 are arranged in a straight line on the top of the table top 7.

[0026] The working principle and usage process of the present invention are as follows: when welding steel, one side of the steel is fitted with the positioning plate 6 so that one side of the steel is vertical, and then the steel is pushed to pass the position of the welding head 401. The fixed wheel group 405 on the top of the welding head 401 will fit the vertical surface of the steel. Then, when the bottom of the steel passes through the shell 402, if the other side of the steel has an angle change such as 90°, 60° or 40°, the steel will first squeeze the movable wheel 406 at the bottom of the shell 402. When the movable wheel 406 is squeezed, the spring 416 is compressed and the slider 415 is controlled to move. The slider 415 can slide up and down and tilt left and right. When it adapts to the inclined surface of the steel, it will synchronously drive the rotating rod 403 to rotate, and the rotating rod 403 will drive the driving wheel 409 to rotate, and the driving wheel 409 drives the meshing When the engaging wheel 408 rotates, the meshing wheel 408 drives the driven wheel 407 to rotate. The transmission ratio of the gear is pre-adjusted. At this time, the welding head 401 will rotate to a better welding angle to complete the overall welding. When changing to the next steel with a different angle, it will continue to adapt to the change without manual adjustment. When the welding mode needs to be switched, the positioning rod 404 and the rotating rod 403 can be folded and stored. When folding, the positioning rod 404 rotates directly backward, and then the pin 414 is rotated and removed, and one of the shells 402 can be removed. Then, the meshing wheel 408 can be pinched by hand to rotate the rotating rod 403 for folding, and the driving wheel 409 can rotate. Due to the large damping degree, the user needs to apply a little force. The damping is greater than the rotational friction of the welding head 401, so it does not affect the normal use in the non-folded state.

[0027] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
