[0002] Steel structure welding machines are specialized equipment used for welding steel structures, playing a vital role in industrial manufacturing. Steel structures are widely used in high-rise buildings, bridges, industrial plants, and other construction applications due to their high strength, excellent seismic resistance, and long service life. Welding, a critical connection process in steel structure manufacturing, directly impacts the safety and economic efficiency of the entire structure.

[0003] In the prior art, during the welding process of steel structures, in order to meet the requirements of erecting and flipping the steel structures, a clamping mechanism connected to the output end of the electric drive device is usually used to directly clamp and erect the steel structure, resulting in the output end of the electric drive device connected to the clamping mechanism needing to bear the weight of the steel structure accordingly. When the weight of the steel structure is large, the load weight of the output end of the electric drive device will be large, and during the welding process of the workpiece, the output end of the electric drive device needs to be responsible for bearing the weight of the workpiece all the time, which will affect the service life of the electric drive device and increase the maintenance and use costs of the equipment.

[0004] In view of the above-mentioned defects, an automatic welding device for steel structure workpieces is provided. Utility Model Content

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 The utility model provides a technical solution: an automatic welding device for steel structure workpieces, comprising a track 1 and a welding mechanism 18 arranged on one side of the track 1, a base 3 is slidably connected to the track 1, and a moving component for driving it to slide along the track 1 is provided on the base 3, a vertical plate 9 is fixed on the base 3, and a fixed plate 11 is slidably connected to the inner side of the vertical plate 9, and a component for driving the fixed plate 11 to move vertically along the vertical plate 9 is provided on the base 3, and a supporting structure for clamping and placing the steel structure workpiece is provided on the fixed plate 11.

[0024] The base 3 is controlled to slide along the track 1 by the moving parts, and the distance between the two vertical plates 9 is adjusted according to the size of the steel structure workpiece. By controlling the fixed plate 11 to slide vertically along the vertical plate 9, the position of the supporting structure relative to the placement groove 901 is adjusted, so that the supporting structure arranged on the fixed plate 11 can clamp and place steel structure workpieces of different sizes.

[0025] Vertical plate 9 is provided with a semicircular opening 901 for workpiece placement. Large steel workpieces can be lifted upward using a crane. Due to the semicircular opening of trough 901, the workpiece can be directly placed into the semicircular opening. The coordinated arrangement of trough 901 and the supporting structure facilitates direct placement of the steel workpiece to be welded relative to vertical plate 9, simplifying the process of placing the steel workpiece relative to vertical plate 9.

[0026] Specifically, such as Figure 1-3 As shown, the moving part includes a servo motor 4 mounted on a base 3 , a gear 5 is mounted on the output end of the servo motor 4 , and a helical rack 2 meshing with the gear 5 is formed on the side wall of the track 1 .

[0027] Servo motor 4 is a conventional electric motor capable of precisely controlling position, speed, and acceleration, offering high precision, speed, and efficiency. Servo motor 4 controls the rotation of gear 5, which, in turn, meshes with helical rack 2 and drives base 3 along track 1, adjusting the spacing between vertical plates 9.

[0028] A guide wheel 7 is rotatably connected to the base 3 through a mounting base 6 , and the guide wheel 7 is in contact with the side surface of the track 1 . A roller 8 is rotatably connected to the base 3 , and the roller 8 is in contact with the upper end surface of the track 1 .

[0029] By coordinating the guide wheel 7 and the roller 8, the base 3 and the track 1 can move and cooperate with each other through rolling friction, thereby reducing the friction resistance between the base 3 and the track 1, which is conducive to the smooth movement of the base 3 along the track 1.

[0030] Specifically, such as Figure 2 As shown, the components that drive the fixed plate 11 to move vertically along the vertical plate 9 include two side plates 10 fixed to the inner end of the vertical plate 9, and the opposite sides of the two side plates 10 are rotatably connected to a screw rod 16, and the screw rod 16 is screwed together with the fixed plate 11. The inner end of the vertical plate 9 is installed with a bidirectional driving mechanism 17 that controls the synchronous rotation of the two screw rods 16.

[0031] The two screw rods 16 are controlled to rotate synchronously by the bidirectional driving mechanism 17 , so that the fixing plate 11 screwed together with the screw rods 16 is driven to move in the vertical direction along the vertical plate 9 .

[0032] The bidirectional drive mechanism 17 includes a square shell installed at the outer end of the vertical plate 9, with a shaft connected to the square shell for rotation. A drive motor for controlling the rotation of the shaft is installed on the square shell, and the end of the shaft away from the square shell drives the screw 16 to rotate through a bevel gear transmission structure.

[0033] The square housing is also provided with a bevel gear structure for driving the output end of the motor to vertically transmit the shaft. The shaft is rotated by the driving motor, and the screw rod 16 vertically distributed to the shaft is driven to rotate at both ends of the shaft through the bevel gear structure.

[0034] Specifically, such as Figure 2 As shown, the supporting structure includes two clamping plates 14 slidably connected to the fixed plate 11, and a hydraulic cylinder 15 for controlling the horizontal sliding of the clamping plate 14 is installed on the fixed plate 11. An optical axis 13 is rotatably connected in the fixed plate 11 to cooperate with the bottom frame of the workpiece, and a bearing plate 12 is fixed on the fixed plate 11 to rotatably connect to the end of the optical axis 13.

[0035] The position of the fixing plate 11 relative to the placement groove 901 is adjusted according to the size of the steel structure, so that the steel structure can be arranged in the center relative to the center of the placement groove, thereby facilitating the subsequent flipping mechanism installed on the vertical plate 9 to flip the steel structure workpiece embedded in the placement groove 901.

[0036] The optical axis 13 is used to bear the weight and support the bottom of the steel structure workpiece. The distance between the two clamping plates 14 is adjusted by the hydraulic cylinder 15 to clamp the steel structure workpiece placed on the optical axis 13 to ensure that the steel structure workpiece maintains a stable state relative to the vertical plate 9 during welding. The rotational friction of the optical axis 13 is reduced by the setting of the bearing plate 12.

[0037] When the steel structure workpiece needs to be removed from the vertical plate 9, it is only necessary to place a bracket responsible for supporting the workpiece at the bottom of the suspended steel structure, and then control the base 3 to move along the track 1 through the moving parts, so that the optical axis 13 moves with the vertical plate 9 and is pulled out from the bottom of the steel structure workpiece in a rolling manner, thereby effectively avoiding wear on the bottom of the workpiece and achieving the purpose of facilitating the removal of the workpiece from the vertical plate 9.

[0038] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
