[0046] Embodiment:

[0047] This embodiment provides an H-shaped steel spot welding and assembling machine, which is used to solve the technical problem of low welding efficiency of the H-shaped steel spot welding and assembling machine in the prior art. The H-shaped steel spot welding and assembling machine includes a machine base 1, a conveying assembly, a welding gun 3, a first driving assembly, and a controller 5, wherein:

[0048] The machine base 1 is a structural member made of steel.

[0049] The conveying assembly is installed on the machine base 1. The conveying assembly is used to convey the workpiece to be welded. Through the setting of the conveying assembly, manual feeding is not required, which saves time and effort.

[0050] The welding gun 3 is installed on the machine base 1 and is located on one side of the conveying assembly. The welding gun 3 is used to weld the workpiece.

[0051] The first driving assembly is installed between the welding gun 3 and the machine base 1. The first driving assembly is used to drive the welding gun 3 to reciprocate along the conveying direction of the conveying assembly. In this way, through the setting of the first driving assembly, the welding gun 3 is movably installed on the machine base 1, so as to achieve the purpose of the workpiece and the welding gun 3 moving in the same direction.

[0052] The controller 5 is electrically connected to the conveying assembly, the welding gun 3, and the first driving assembly through wires. Through the setting of the controller 5, the relative moving speed between the conveying assembly and the first driving assembly, and the start and stop of the welding gun 3 are controlled, so as to achieve the purpose of welding the workpiece without reducing the moving speed of the workpiece.

[0053] With the above structure, when using the H-shaped steel spot welding and assembling machine provided by the present utility model to weld H-shaped steel, first, the workpiece to be welded is conveyed to the welding starting point by the conveying assembly, and then the controller 5 controls the first driving assembly to start moving along the conveying direction of the conveying assembly, thereby driving the welding torch 3 mounted on the first driving assembly to start moving along the conveying direction of the conveying assembly, so that the relative speed between the welding torch 3 and the workpiece is equal to the welding speed of the welding torch 3 for welding the workpiece. Then the welding torch 3 arcs to start welding. When the set weld length is reached, the welding torch 3 extinguishes the arc, and the workpiece continues to move forward under the action of the conveying assembly, while the welding torch 3 returns to the welding starting point under the action of the first driving assembly, and then the next welding is carried out. The above welding process is repeated until the entire workpiece assembly is completed and the welding stops. In this way, through the setting of the first driving assembly and the controller 5, the welding torch 3 welds the workpiece while moving, and there is no need for the workpiece to decelerate or stop for spot welding during the welding process, so that the welding efficiency of the H-shaped steel spot welding and assembling machine provided by the present utility model is higher.

[0054] An optional implementation manner of this embodiment is as follows: The conveying assembly includes a plurality of conveying rollers 2, which are all rotatably mounted on the machine base 1.

The welding torch 3 is mounted on the moving end of the linear module 4, and the moving direction of the linear module 4 is the conveying direction of the conveying assembly. Optionally, the linear module 4 is selected as a servo motor, with more flexible movement and more accurate positioning.

[0056] An optional implementation manner of this embodiment is as follows: It further includes a first mounting bracket 6, which is mounted between the linear module 4 and the welding torch 3. The first mounting bracket 6 includes a first connecting rod 61, a mounting plate 62, and a second connecting rod 63, where:

[0057] One end of the first connecting rod 61 is mounted on the linear module 4. In this way, when the linear module 4 moves, it drives the first connecting rod 61 to move synchronously.

The side of the mounting plate 62 away from the workpiece is higher than the side of the mounting plate 62 close to the workpiece. The welding torch 3 is mounted on the mounting plate 62. In this way, the movement of the first connecting rod 61 drives the mounting plate 62 to rotate synchronously. At the same time, the inclined mounting plate 62 is more convenient for the welding torch 3 to weld the workpiece.

[0059] Both ends of the second connecting member are respectively installed on the first connecting rod 61 and the mounting plate 62. In this way, through the arrangement of the second connecting member, the connection between the first connecting rod 61 and the mounting plate 62 is strengthened, making the structure of the mounting rack more stable.

[0060] Optionally, the range of the included angle α is: 30° ≤ α ≤ 70°. Exemplarily, the included angle α can be 30°, 40°, 50°, 60° or 70°.

The second driving component 7 is used to drive the first mounting rack 6 to move in the second direction, and the second direction is perpendicular to the moving direction of the linear module 4. In this way, through the arrangement of the driving component, it is convenient to adjust the distance between the welding torch 3 and the workpiece, so as to be applicable to workpieces of different thicknesses, and the applicability is stronger.

[0062] Optionally, the second driving component 7 includes a mounting frame 71, a sliding plate 72, a sliding block 73 and a screw rod 74, where:

[0063] The mounting frame 71 is installed on the linear module 4. Specifically, the mounting frame 71 is composed of four side plates and a bottom plate. The bottom plate is installed on the moving end of the linear module 4, and the four side plates are respectively installed on the four sides of the bottom plate.

[0065] One side of the sliding block 73 is provided with a through hole adapted to the sliding plate 72, and the sliding plate 72 is slidably inserted into the through hole. The first connecting rod 61 is detachably installed on the sliding block 73.

[0066] One end of the sliding block 73 is provided with a threaded through hole, and one end of the screw rod 74 extends into the mounting frame 71 and is screwed into the threaded through hole.

[0067] With the above structure, when it is necessary to move the welding torch 3, only need to rotate the screw rod 74, so that the sliding block 73 moves on the screw rod 74, and at the same time drive the sliding block 73 to move on the sliding plate 72, thereby driving the first connecting rod 61 installed on the sliding block 73 to move together, and further making the welding torch 3 move in the direction close to or away from the workpiece.

[0068] Optionally, it further includes a handle 8 installed at one end of the screw rod 74 extending out of the mounting frame 71. In this way, through the arrangement of the handle 8, it is more convenient to rotate the screw rod 74.

[0069] An alternative implementation of this embodiment is as follows: It further includes a second mounting rack 9 installed on the machine base 1. The second mounting rack 9 is used to install the linear module 4. The second mounting rack 9 includes a third connecting rod 91, a vertical rod 92, a cross rod 93 and a fourth connecting rod 94, where:

[0070] The third connecting rod 91 is detachably mounted on the machine base 1.

[0071] The vertical rod 92 is mounted on the third connecting rod 91.

[0072] The cross rod 93 is mounted on the top end of the vertical rod 92, and the linear module 4 is mounted on the cross rod 93.

[0073] Both ends of the fourth connecting rod 94 are respectively mounted on the vertical rod 92 and the cross rod 93. In this way, through the detachably mounted third connecting rod 91, it is convenient to disassemble and repair the welding torch 3, and the arrangement of the fourth connecting rod 94 strengthens the connection between the cross rod 93 and the vertical rod 92, making the structure of the second mounting bracket 9 more stable.
