Description

Technical Field

[0001] This invention relates to the field of welding technology, and more specifically to a welding apparatus for steel structure columns. Background Technology

[0002] Laser welding utilizes high-energy laser pulses to locally heat materials. The energy from the laser radiation diffuses through the heat-conducting material, melting it to form a specific molten pool. It is a novel welding method. To weld two square-tube steel structural columns together to form a single straight or V-shaped component, the welding surfaces of the two steel structures must be aligned and clamped to achieve the connection. During the connection process, the two sets of columns must be joined and clamped. The welding torch is positioned at the connection point to perform the welding. After welding, clamps are used to hold the steel structures to prevent movement during the welding process. However, since the steel columns are hollow, excessive force can cause deformation, affecting their normal use. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a steel structure column welding device to overcome the above-mentioned defects in the existing technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A steel structure column welding device includes a welding robot and a frame. The frame includes a fixed base and an adjustable base, which are respectively disposed on both sides of the welding robot. The fixed base is used to fix the mounting base. The adjustable base holds the column and is provided with a welding station and a clamping mechanism. The clamping mechanism includes a fixed plate and a mounting plate, which are disposed opposite to each other on both sides of the welding station. The mounting plate is provided with a clamping component, which includes a limiting plate, a first elastic element, and a scissor fork structure. The limiting plate is disposed between the mounting plate and the fixed plate and is parallel to the mounting plate. The first elastic element and the scissor fork structure are both disposed between the limiting plate and the mounting plate. The first elastic element drives the limiting plate to move toward the side where the fixed plate is located. The scissor fork structure is provided with a locking mechanism. A placement plate is disposed between the fixed plate and the mounting plate. A pushing component is provided at the bottom of the placement plate. The pushing component drives the placement plate to move up and down so that the placement plate moves closer to or away from the welding station.

[0006] Preferably, a top plate is arranged parallel above the placement plate, with both ends of the top plate pressing against the fixing plate and the mounting plate respectively. An upper pressure plate is provided on the side of the top plate near the placement plate, and an adjusting component is provided on the top plate. The adjusting component drives the upper pressure plate to move up and down so that the upper pressure plate moves closer to or away from the placement plate.

[0007] Preferably, the adjusting component includes two sets of hinge rods, a coil, and a second elastic element. Both sets of hinge rods are hinged to the top of the upper pressure plate and are arranged opposite to each other. A sliding groove is provided at the bottom of the top plate, and both sets of hinge rods are slidably disposed in the sliding groove. Two sets of pull ropes are wound on the coil and are respectively fixedly connected to the two sets of hinge rods. The coil is rotatably disposed on the top plate, and the second elastic element presses against the top plate and the upper pressure plate to make the upper pressure plate move toward the side where the top plate is located.

[0008] Preferably, the coil is provided with an adjustment mechanism, which includes a ratchet, a pawl, and a disc spring. The ratchet is fixedly installed on the coil, and the disc spring is disposed on the ratchet. The disc spring is used to drive the ratchet to reset. One end of the pawl is hinged to the top plate, and the other end of the pawl presses against the ratchet.

[0009] Preferably, a motor is connected to one end of the top plate near the fixed plate. The top plate has a first position and a second position. When the top plate presses against the mounting plate, the top plate is in the first position. When the top plate is detached from the mounting plate, the top plate is in the second position. The adjustment mechanism also includes a pressing member and a tension spring. The tension spring is disposed on the pawl and drives the pawl to move away from the ratchet. When the top plate is in the first position, the pressing member presses against the pawl so that the ratchet contacts the pawl. When the top plate is in the second position, the pressing member disengages from the pawl, and the ratchet disengages from the pawl.

[0010] Preferably, the top plate is provided with a slide rail, the slide groove and the ratchet are respectively provided on both sides of the pawl, and the other end of the slide rail is provided on the side where the fixed plate is located. The slide rail is inclined downward from the side where the fixed plate is located to the side where the pawl is located, and the pressing member is slidably provided in the slide rail.

[0011] Preferably, the pushing assembly includes an intermediate plate and a cylinder. The intermediate plate is disposed at the bottom of the placement plate, and a plurality of third elastic members are disposed between the placement plate and the intermediate plate. The cylinder is disposed at the bottom of the intermediate plate.

The scissor fork structure is opened or closed so that the sliding block is slidably disposed in the sliding groove. The scissor fork structure includes an initial state, a locked state, and an elastic state. When the scissor fork structure is in the initial state, the locking mechanism drives the limiting plate away from the fixed plate. When the scissor fork structure is in the locked state, the limiting plate presses against the column, and the sliding block is fixedly installed in the sliding groove. When the scissor fork structure is in the elastic state, the limiting plate presses against the column, and the sliding block is slidably disposed in the sliding groove.

[0014] Preferably, the adjusting seat is slidably provided with a slide table structure and a driving structure. The welding station and the clamping mechanism are both provided on the slide table structure. The driving structure drives the slide table structure to move so that the slide table structure moves closer to or further away from the fixed seat.

[0015] The beneficial effects of this invention are as follows: The use of a first elastic element and a scissor fork structure drives the movement and locking of the limiting plate, avoiding column deformation due to excessive force acting on the limiting plate without affecting the clamping effect. A placement plate is provided between the fixing plate and the mounting plate, with a pushing component at the bottom of the placement plate. The pushing component drives the placement plate to move up and down, allowing it to move closer to or further away from the welding station. A placement plate is provided at the welding station 11, and the pushing component drives the placement plate to move up and down, thereby causing the column to move up and down. Before welding, the column and base can be fine-tuned to ensure accurate positioning of the welding position.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings:

[0027] like Figures 1-6As shown, this invention provides a steel structure column welding device, including a welding robot 6 and a frame 7. The frame 7 includes a fixed base 1 and an adjustable base 2, which are respectively disposed on both sides of the welding robot 6. The fixed base 1 is used to fix the mounting base, and the column is placed on the adjustable base 2. The adjustable base 2 is provided with a welding station 11 and a clamping mechanism 3. The welding station 11 is used to place the column, and the clamping mechanism 3 is used to clamp the column and connect the column to the base, ensuring the stability of both during the welding process. The clamping mechanism 3 includes a fixed plate 31 and a mounting plate 32, which are disposed opposite to each other on the welding station 6. On both sides of the welding station 11, the mounting plate 32 is provided with clamping members 33. These clamping members 33 are used to push the column on the welding station 11 towards the side where the fixing plate 31 is located, while simultaneously ensuring that the column is clamped on the welding station 11. The clamping member 33 includes a limiting plate 331, a first elastic member 333, and a scissor fork structure 332. The limiting plate 331 is located between the mounting plate 32 and the fixing plate 31, and is parallel to the mounting plate 32. The first elastic member 333 and the scissor fork structure 332 are both located between the limiting plate 331 and the mounting plate 32. The first elastic member 333 drives the limiting plate 331 to move towards the side where the fixing plate 31 is located, thus pressing the column firmly. A locking mechanism 334 is provided on the scissor fork structure 332. The locking mechanism 334 locks the scissor fork structure 332, causing the limiting plate 331 to move away from the fixed plate 31. Simultaneously, the first elastic element 333 is in a compressed state. When the column is placed on the welding station 11, the locking mechanism 334 opens, and the limiting plate 331 is pushed out by the first elastic element 333, driving the scissor fork structure 332 to move. When the limiting plate 331 presses against the column, the locking mechanism 334 relocks the scissor fork structure 332, achieving the pressing of the limiting plate 331 against the column. This is a significant improvement over existing methods that directly use a motor to drive the limiting plate. For the positioning plate 331, a first elastic element 333 and a scissor fork structure 332 are used to drive the movement and locking of the limiting plate 331. While not affecting the pressing effect, it avoids the deformation of the column due to excessive force acting on the limiting plate 331. A placement plate 5 is provided between the fixing plate 31 and the mounting plate 32. A pushing component is provided at the bottom of the placement plate 5. The pushing component drives the placement plate 5 to move up and down, so that the placement plate 5 moves closer to or away from the welding station 11. The placement plate 5 is provided on the welding station 11. The pushing component drives the placement plate 5 to move up and down, thereby driving the column to move up and down. Before welding, the column and the base can be finely adjusted to ensure the accurate positioning of the welding position.

[0028] The clamping mechanism 3 is also provided with a top plate 34, which is parallel to the placement plate 5. The two ends of the top plate 34 press against the fixing plate 31 and the mounting plate 32 respectively. The fixing plate 31 and the mounting plate 32 are used to install the top plate 34 on the clamping mechanism 3. An upper pressure plate 4 is provided on the side of the top plate 34 near the placement plate 5. An adjusting component is provided on the top plate 34. The adjusting component drives the upper pressure plate 4 to move up and down so that the upper pressure plate 4 moves closer to or away from the placement plate 5. During the column clamping process, the adjusting component drives the upper pressure plate 4 to move downward so that the upper pressure plate 4 is pressed on the column.

[0029] The adjusting component includes two sets of hinge rods 411, a coil 412, and a second elastic element 413. Both sets of hinge rods 411 are hinged to the top of the upper pressure plate 4 and are arranged opposite to each other. A sliding groove is provided at the bottom of the top plate, and both sets of hinge rods 411 are slidably disposed within the groove. Two sets of pull ropes are wound around the coil 412, and the two sets of pull ropes are respectively fixedly connected to the two sets of hinge rods 411. The coil 412 is rotatably disposed on the top plate 34. The second elastic element 413 presses against the top plate 34 and the upper pressure plate 4, causing the upper pressure plate 4 to move towards the side where the top plate 34 is located. During installation... During the process, the pull rope is tightened by rotating the coil 412. During the tightening of the pull rope, the hinge rod 411 slides in the groove, and the upper pressure plate 4 moves towards the side where the placement plate 5 is located. At the same time, after the coil 412 is released, the upper pressure plate 4 is reset under the action of the second elastic element 413 and moves towards the side where the top plate 34 is located, realizing the separation of the upper pressure plate 4 from the column, which facilitates the removal of the column. The upper pressure plate 4 is driven by the coil 412 to achieve a more stable movement of the upper pressure plate 4, avoiding excessive force exerted by the upper pressure plate 4 on the column, which could cause the column to deform.

[0030] An adjustment mechanism is provided on the coil 412. The adjustment mechanism includes a ratchet 414, a pawl 415, and a coil spring. The ratchet 414 is fixedly installed on the coil 412, and the coil spring is set on the ratchet 414. The coil spring is used to drive the ratchet 414 to reset. One end of the pawl 415 is hinged to the top plate 34, and the other end of the pawl 415 presses against the ratchet 414. Utilizing the structure of the ratchet 414, pawl 415, and coil spring, during the tightening process of the coil 412, the pawl 415 presses against the ratchet 414, causing the ratchet 414 to rotate. At the same time, the coil spring deforms. After the coil 412 is released, the pawl 415 presses against the ratchet 414 to prevent the ratchet 414 from rotating and resetting.

[0031] A motor is connected to one end of the top plate near the fixed plate 31. The top plate 34 has a first position and a second position. When the top plate 34 presses against the mounting plate 32, the top plate 34 is in the first position. When the top plate 34 is disengaged from the mounting plate 32, the top plate 34 is in the second position. The adjustment mechanism also includes a pressing member 417 and a tension spring. The tension spring is disposed on the pawl 415 and drives the pawl 415 to move away from the ratchet 414. When the top plate 34 is in the first position, the pressing member 417 presses against the pawl 415 so that the ratchet 414 contacts the pawl 415. When the top plate 34 is in the second position, the pressing member 417 disengages from the pawl 415, and the ratchet 414 disengages from the pawl 415. The top plate 34 is rotated by a motor, allowing it to be placed horizontally or vertically. When the top plate 34 is horizontal, the pressing member 417 presses against the pawl 415, achieving the combination of ratchet 414 and pawl 415. Simultaneously, during the rotation of the coil 412, the ratchet 414 can drive the pawl 415 to move without affecting the normal use of the ratchet 414 and pawl 415. When the top plate 34 is vertically set by the motor, the pressing member 417 disengages from the pawl 415, and the pawl 415 disengages from the ratchet 414 under the action of the tension spring. The ratchet 414 resets under the action of the disc spring, achieving the reverse rotation of the ratchet 414, releasing the coil 412, and resetting the upper pressure plate 4.

[0032] A slide rail 416 is provided on the top plate 34. The slide rail 416 and ratchet 414 are respectively provided on both sides of the pawl 415, and the other end of the slide rail 416 is provided on the side where the fixed plate 31 is located. The slide rail 416 is inclined downward from the side where the fixed plate 31 is located to the side where the pawl 415 is located. The pressing member 417 is slidably provided in the slide rail 416. The top plate 34 is provided with an inclined slide rail 416. When the top plate 34 is in the first position, the end of the slide rail 416 near the fixed plate 31 is higher than the end of the slide rail 416 near the ratchet 414, so that in the first position, the pressing member 417 presses against the pawl 415 to achieve the clamping of the pawl 415. At the same time, after the motor drives the top plate 34 to open, the pressing member 417 slides along the slide rail 416 and disengages from the pawl 415, realizing the separation of the ratchet 414 and the pawl 415.

[0033] The pushing assembly includes an intermediate plate 51 and a cylinder. The intermediate plate 51 is located at the bottom of the placement plate 5, and several sets of third elastic elements 511 are arranged between the placement plate 5 and the intermediate plate 51. The cylinder is located at the bottom of the intermediate plate 51. The pushing assembly includes the intermediate plate 51 and the cylinder. The cylinder drives the intermediate plate 51 to move up and down. During the welding process, the cylinder drives the upper pressure plate 4 to move up and down to adjust the height of the column. At the same time, it drives the upper pressure plate 4 to move to clamp the column. The third elastic elements 511 are pressed and welded. After the four welding points around the column are welded, the cylinder is released to a certain extent, the intermediate plate 51 moves downward, the third elastic elements 511 are released, and the welding of the column is carried out around the column. The weld is dynamically adjusted to avoid excessive rigidity during the welding process, which would affect the stress at the weld.

[0034] The mounting plate 32 is provided with a sliding groove, and the scissor fork structure 332 is provided with a sliding block. The scissor fork structure 332 is opened or closed so that the sliding block is slidably disposed in the sliding groove. The scissor fork structure 332 includes an initial state, a locked state, and an elastic state. When the scissor fork structure 332 is in the initial state, the locking mechanism 334 drives the limiting plate 331 away from the fixed plate 31. When the scissor fork structure 332 is in the locked state, the limiting plate 331 presses against the column, and the sliding block is fixedly installed in the sliding groove. When the scissor fork structure 332 is in the locked state, the locking mechanism 334 drives the limiting plate 331 away from the fixed plate 31. When the scissor fork structure 332 is in the locked state, the limiting plate 331 presses against the column, and the sliding block is fixedly installed in the sliding groove. When structure 332 is in an elastic state, the limiting plate 331 presses against the column, and the sliding block is slidably disposed in the sliding groove. During the welding process, after welding the four connection points of the column, the scissor fork structure 332 transitions from a locked state to an elastic state, reducing the force exerted by the limiting plate 331 on the main body, and facilitating the adjustment and welding of the main body. The locking mechanism 334 is a hydraulic component, and the output end of the hydraulic component is fixedly installed on the sliding block. The sliding block is driven to move up and down by the hydraulic component to adjust the working state of the scissor fork.

[0035] The adjusting seat 2 is equipped with a sliding table structure and a driving structure. The welding station 11 and the clamping mechanism 3 are both set on the sliding table structure. The driving structure drives the sliding table structure to move so that the sliding table structure moves closer to or away from the fixed seat 1. The adjusting seat 2 is equipped with a sliding table structure. The driving structure drives the sliding table structure to move so that the sliding table structure moves closer to or away from the fixed seat 1, thereby realizing the docking of the column and the base.
