[0001] The utility model relates to the technical field of welding machines, and particularly refers to a device for welding stiffeners. Background Art

[0002] In the existing galvanometer laser welding equipment, the galvanometer is installed on a robotic arm fixed to the workbench, and the travel of the robotic arm is controlled by a computer to complete welding. However, in the welding operation of the stiffeners of a metal door, it is necessary to weld the "U-shaped" stiffeners behind the metal door, and there are many sizes of the metal door and the stiffeners. The existing galvanometer laser welding equipment does not have the function of positioning and stabilizing the stiffeners, which is prone to miswelding, resulting in a high rate of defective products and needs to be improved. Content of the Utility Model

[0003] In view of the above problems, the utility model provides a device for welding stiffeners to solve one or more technical problems existing in the prior art, and at least provides a beneficial choice or creation condition.

[0004] To achieve the above object, the technical scheme adopted by the utility model is as follows:

[0005] A device for welding stiffeners includes a frame. The frame is provided with a door beam extending longitudinally. The door beam is slidably connected with a pressing component. The pressing component includes at least two pressing feet respectively pressing on both sides of the stiffener. A galvanometer is arranged above the pressing component at the pressing feet.

[0006] Preferably, rollers are installed at the ends of the pressing feet.

[0007] Preferably, the rollers on both sides of the stiffener are arranged oppositely.

[0008] Preferably, the two pressing feet are connected with an adjusting component, and the adjusting component is connected with a hand wheel

[0009] Preferably, the adjusting component is a screw rod component.

[0010] Preferably, the pressing component further includes a positioning member abutted against the outer side of the stiffener.

[0011] Preferably, the positioning member includes two positioning rods respectively abutted against the outer side of the stiffener.

[0012] Preferably, the positioning rod includes two support rods respectively abutted against the outer side of the stiffener.

[0013] Preferably, the lower ends of the support rods do not contact the upper surface of the stiffener.

[0014] Advantages of the Utility Model

[0015] 1. This utility model uses a frame to install a door beam, which is slidably connected to a pressing assembly. The pressing assembly is equipped with a galvanometer, which can move the galvanometer and the frame together. One frame can be adapted to different workbenches, thus improving work efficiency.

[0016] 2. Before welding with the galvanometer, press the two sides of the reinforcing rib firmly onto the metal door panel using rollers to ensure accurate weld points and tight welding.

[0017] 3. By setting a support rod that abuts against the side of the reinforcing rib, the reinforcing rib can be accurately positioned, improving work efficiency. Attached Figure Description

[0023] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0024] Example: Refer to Figures 1 to 4The present invention discloses a device for welding reinforcing ribs, comprising a frame 1, a door beam 2 extending longitudinally from the frame 1, a pressing assembly 3 slidably connected to the door beam 2, and the pressing assembly 3 running along the door beam 2 driven by a motor 13. The pressing assembly 3 includes at least two press feet 4 pressing on both sides of the reinforcing rib, and a galvanometer 6 positioned above the press feet 4. The pressing assembly 3 runs above a workbench 12 to weld reinforcing ribs onto a door panel above the workbench 12. During operation, the door panel to be welded and the reinforcing rib are placed on the workbench 12. A first cylinder 14 on the pressing assembly 3 pushes the press feet 4 downwards to above the reinforcing rib, and then a third cylinder 16 on the press feet 4 pushes the press feet 4 downwards to press on the edges of both sides of the reinforcing rib, stabilizing the reinforcing rib. Subsequently, the motor 13 starts, driving the pressing assembly 3 forward, with the press feet 4 following and pressing and positioning, and the galvanometer 6 welding the reinforcing rib. This ensures that the reinforcing rib does not shift during welding, ensuring welding accuracy and improving work efficiency and welding quality.

[0025] Specifically, rollers 9 are installed at the end of the presser foot 4. In the preferred embodiment, the rollers 9 on both sides of the reinforcing rib are arranged opposite each other. The rollers 9 press on both sides of the reinforcing rib, and the vertical force of the rollers 9 presses on both sides of the reinforcing rib. The rolling of the rollers 9 has less friction on the reinforcing rib and has less impact on the welding of the reinforcing rib.

[0026] Specifically, the two presser feet 4 are connected to an adjustment component 7, and the adjustment component 7 is connected to a handwheel 8. By rotating the handwheel 8, the adjustment component 7 can be rotated, which can quickly adjust the distance between the presser feet 4, quickly adapt to reinforcing ribs of different widths, and improve work efficiency. In a preferred embodiment, the adjustment component 7 is a lead screw assembly. During adjustment, the two presser feet 4 move towards each other or in opposite directions to improve adjustment efficiency.

[0027] Specifically, the pressing assembly 3 also includes a positioning member 5 that abuts against the outside of the reinforcing rib. During operation, the positioning member 5 moves downward with the pressing assembly 3. The third cylinder 16 on the press foot 4 pushes the press foot 4 downward to press against the edges on both sides of the reinforcing rib. The second cylinder 15 of the positioning member 5 pushes the positioning member 5 downward to a height that can abut against the side of the reinforcing rib. The operator abuts the outside of the reinforcing rib against the positioning member 5 to position the reinforcing rib. During welding, the motor 13 starts and drives the pressing assembly 3 forward. The positioning member 5 follows and positions the reinforcing rib, while the galvanometer 6 welds the reinforcing rib.

[0028] Specifically, the positioning component 5 includes two positioning rods 10, and each positioning rod 10 includes two support rods 11. The support rods 11 abut against the outside of the reinforcing rib, and the four points formed by the support rods 11 are used to position the reinforcing rib, making the positioning of the reinforcing rib more stable.

[0029] Specifically, the lower end of the support rod 11 does not contact the upper surface of the stiffener, but only abuts against the side waist of the "U" - shaped stiffener. The lower end of the support rod 11 does not contact the edge of the stiffener, which can avoid disturbing the stiffener caused by the lower end of the support rod 11 hitting the edge of the stiffener, thus ensuring the stable and accurate positioning of the stiffener.
