Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, and particularly relates to a welding device for a right-angle steel structure. Background Technique

[0002] Right-angle steel is a kind of steel with a right-angled cross-section, which has good strength and stiffness, and is easy to process and weld. A right-angle steel structure is a structure processed by welding and other processes using right-angle steel as raw materials; Figure 1 It is a common steel frame structure on the market. This steel frame structure is composed of multiple horizontally and vertically coordinated angle steels welded together, that is, multiple horizontal angle steels are fixed between two vertically parallel angle steels, and the horizontal angle steels and the vertical angle steels are fixed by welding.

[0003] At the present stage, when using welding equipment to weld this steel frame structure, the staff will directly place multiple angle steels between the angle steels on both sides and then directly weld and fix them. However, during the welding process, due to the lack of effective limiting and fixing measures, the multiple angle steels are very likely to shift and misalign, which will lead to the problem of welding deviation and seriously affect the processing quality of the steel frame structure. In view of this, we propose a welding device for a right-angle steel structure. Content of the Utility Model

[0034] A connecting frame 13 is fixed to the bottom of the base 1. A double-headed lead screw 14 is rotatably installed in the opening of the connecting frame 13 along the length direction. A first motor 130 for driving the double-headed lead screw 14 to rotate is installed on the front end face of the connecting frame 13. Connecting seats 15 are threadedly connected to the outer sides of both ends of the double-headed lead screw 14. The tops of the two connecting seats 15 respectively pass through the two grooves 12 and extend to the outside and are both fixed with fixing seats 16. Clamping grooves are formed on the opposite side surfaces of the two fixing seats 16, and a horizontally and longitudinally arranged first angle steel is placed in the two clamping grooves. Brackets 17 are fixed at both ends of each fixing seat 16. A first electric cylinder 18 is installed on the outer wall of each bracket 17.

Two second electric cylinders 22 for driving the connecting block 21 to lift are installed on the top of the movable seat 20. A fixing frame 23 is fixed to the front side of the connecting block 21. The inner bottom of the opening of the fixing frame 23 is used for placing a second angle steel arranged horizontally and transversely. Two third electric cylinders 24 are installed on the top of the fixing frame 23. The piston rods of the two third electric cylinders 24 both slide through the top of the fixing frame 23 and extend to the inside. A pressing block 25 is fixed between the ends of the piston rods of the two third electric cylinders 24, and the pressing block 25 is used to limit the second angle steel at the inner bottom of the fixing frame 23.

[0043] It should be added that the automatic three-axis gantry 3 is a device widely used in the field of industrial automation. It is usually composed of motion mechanisms in the X, Y, and Z axes, forming a gantry frame structure. This structure enables the device to perform precise movement and positioning in three-dimensional space and is suitable for various occasions requiring high-precision and high-efficiency processing or assembly. The above is the existing conventional technology and will not be elaborated here. In this embodiment, the laser welding head 30 is installed on the slide table of the automatic three-axis gantry 3, which facilitates the adjustment of the position of the laser welding head 30, thereby meeting the welding requirements of the laser welding head 30 for the angle steel at different positions.

[0044] It is worth noting that the first motor 130 and the second motor 19 involved in this embodiment are existing conventional technologies and will not be elaborated here.

[0045] Before actual use, the user first passes the two first angle steels through the clamping grooves on the two fixing seats 16 respectively. Subsequently, the user turns on the power supply of the first electric cylinder 18. The piston rod of the first electric cylinder 18 extends and drives the clamping block 181 to move. When the clamping block 181 abuts against the first angle steel, the power supply of the first electric cylinder 18 is stopped. Then the user places the second angle steel at the inner bottom of the fixing frame 23 and turns on the power supply of the third electric cylinder 24. The piston rod of the third electric cylinder 24 extends and drives the pressing block 25 to move downward. When the pressing block 25 abuts against the second angle steel, the power supply of the third electric cylinder 24 is stopped; Next, the user turns on the power supply of the first motor 130. The first motor 130 starts to work. The output shaft of the first motor 130 rotates to drive the double-headed lead screw 14 to rotate. At this time, the two connecting seats 15 move synchronously towards each other, and drive the two fixing seats 16 and the two first angle steels to move towards the second angle steel; When the first angle steel contacts both ends of the second angle steel, the power supply of the first motor 130 is stopped. At this time, the user turns on the power supply of the second motor 19. The output shaft of the second motor 19 rotates to drive the threaded rod 11 to rotate. As the threaded rod 11 rotates, the movable seat 20 moves horizontally and drives the second angle steel to move. When the second angle steel moves to the appropriate position, the power supply of the second motor 19 is stopped. Finally, the user turns on the power supply of the second electric cylinder 22. The piston rod of the second electric cylinder 22 extends and drives the fixing frame 23 to move up and down. When the bottom of the second angle steel abuts against the first angle steel, the power supply of the second electric cylinder 22 is stopped;

[0046] During actual welding, the user operates the automatic three-axis gantry 3 to move the laser welding head 30 to the connection between the second angle steel and the first angle steel, and then welding operations can be carried out.
