Description

Technical Field

[0001] The utility model relates to a welding fixture for elevator door panels. Background Technique

[0002] During the production process of elevator door panels, in order to improve their structural strength and safety, stiffeners are usually welded. In this process, the stiffeners are usually pre-fixed on the elevator door panels by methods such as press riveting, and then the elevator door panels are fixed by a fixture and then welded.

[0003] However, the existing fixture design only realizes horizontal fixation on both sides of the elevator door panel, and there is no corresponding fixation measure in the vertical direction, which may cause unnecessary floating of the door panel during the welding process, thereby affecting the welding accuracy and quality. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a welding fixture for elevator door panels to solve the problems raised in the above background technique.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] A welding fixture for elevator door panels includes a bottom plate. Transverse fixing clamping plates are arranged on both sides of the bottom plate. A transverse cylinder is connected to the outer side of the transverse fixing clamping plate. An inner extension plate is arranged on the top surface of the transverse fixing clamping plate. A vertical cylinder is arranged above the inner extension plate. A vertical fixing pressing block is arranged below the inner extension plate. The piston rod of the vertical cylinder passes through the inner extension plate and is connected to the vertical fixing pressing block.

[0007] Preferably, two transverse cylinders are arranged on each side. The two transverse cylinders are spaced apart along the length direction of the bottom plate on the bottom plate.

[0008] Preferably, sliders are arranged on both sides of the transverse fixing clamping plate. Sliding grooves matched with the sliders are arranged on the bottom plate. The sliding grooves are arranged along the width direction of the bottom plate.

[0009] Preferably, an L-shaped plate for fixing the transverse cylinder is arranged on the bottom plate.

[0010] Preferably, a rubber pad is arranged at the bottom of the vertical fixing pressing block.

[0011] Preferably, a through hole through which the piston rod of the vertical cylinder passes is arranged on the inner extension plate.

[0012] Preferably, the distance value between the transverse fixing clamping plate and the vertical fixing pressing block is greater than the width value of the edge of the elevator door panel.

[0013] Preferably, in the initial state, the height value of the bottom surface of the vertical fixing block is greater than the height value of the edge of the elevator door panel.

[0014] The beneficial technical effects of the present utility model:

[0015] By providing horizontal fixing clamps and horizontal cylinders on both sides of the bottom plate, the present utility model can effectively fix the elevator door panel horizontally from both sides, ensuring the stability of the elevator door panel during the welding process, reducing the welding deviation caused by the movement of the elevator door panel. At the same time, by providing a vertical fixing block and a vertical cylinder, the elevator door panel can be vertically fixed from above, further stabilizing the position of the elevator door panel and preventing the elevator door panel from shifting in the vertical direction during welding. This horizontal and vertical two-way fixing mechanism ensures the welding accuracy and quality. Description of the drawings

[0021] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings, but the implementation manners of the present utility model are not limited thereto.

[0022] As Figures 1-4 shown, a welding fixture for an elevator door panel provided in this embodiment includes a bottom plate 1. Horizontal fixing clamps 2 are provided on both sides of the bottom plate 1. A horizontal cylinder 3 is connected to the outside of the horizontal fixing clamps 2. An inner extension plate 4 is provided on the top surface of the horizontal fixing clamps 2. A vertical cylinder 5 is provided above the inner extension plate 4. A vertical fixing block 6 is provided below the inner extension plate 4. The piston rod of the vertical cylinder 5 passes through the inner extension plate 4 and is connected to the vertical fixing block 6. A through hole 11 through which the piston rod of the vertical cylinder 5 passes is provided on the inner extension plate 4.

[0023] During use, place the elevator door panel in the middle of the two horizontally fixed clamping plates 2 on both sides, start the horizontal cylinder 3, so that the horizontally fixed clamping plates 2 clamp on both sides of the elevator door panel, and then start the vertical cylinder 5, so that the vertical fixed pressing block 6 moves downward and finally presses above the elevator door panel.

[0024] In this embodiment, as Figure 1 shown, two horizontal cylinders 3 are provided on each side. The two horizontal cylinders 3 are arranged on the bottom plate 1 and spaced along the length direction of the bottom plate 1, making the clamping more stable.

[0025] In this embodiment, as Figure 1 shown, sliders 7 are provided on both sides of the horizontally fixed clamping plate 2, and sliding grooves 8 that cooperate with the sliders 7 are provided on the bottom plate 1. The sliding grooves 8 are arranged along the width direction of the bottom plate 1, providing precise linear guidance for the horizontally fixed clamping plate 2, ensuring the horizontal stable movement of the horizontally fixed clamping plate 2 during the clamping process, and thus achieving precise positioning of the elevator door panel.

[0026] In this embodiment, as Figure 1 shown, an L-shaped plate 9 for fixing the horizontal cylinder 3 is provided on the bottom plate 1, ensuring the stability of the overall structure.

[0027] In this embodiment, as Figure 1 shown, a rubber pad 10 is provided at the bottom of the vertical fixed pressing block 6 to protect the surface of the elevator door panel from damage when fixing the elevator door panel, avoid scratches or indentations caused by hard contact, and also provide an additional anti-slip effect, enhancing the stability of the fixation.

[0028] In this embodiment, as Figure 1 shown, the distance value between the horizontally fixed clamping plate 2 and the vertical fixed pressing block 6 is greater than the width value of the edge of the elevator door panel. In the initial state, the height value of the bottom surface of the vertical fixed pressing block 6 is greater than the height value of the edge of the elevator door panel. That is, before fixing the elevator door panel, the bottom surface of the vertical fixed pressing block 6 is located above the edge of the elevator door panel. Thus, when fixing, the horizontally fixed clamping plate 2 can drive the vertical fixed pressing block 6 to pass through the edge of the elevator door panel and finally press inside the elevator door panel.

[0029] In summary, in this embodiment, by providing the horizontally fixed clamping plates 2 and the horizontal cylinders 3 on both sides of the bottom plate 1, the elevator door panel can be effectively fixed horizontally from both sides, ensuring the stability of the elevator door panel during the welding process, reducing the welding deviation caused by the movement of the elevator door panel. At the same time, by providing the vertical fixed pressing block 6 and the vertical cylinder 5, the elevator door panel can be vertically fixed from above, further stabilizing the position of the elevator door panel and preventing the elevator door panel from shifting in the vertical direction during welding. This horizontal and vertical two-way fixing mechanism ensures the accuracy and quality of welding.

[0030] As described above, it is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and concept of the present utility model, making equivalent substitutions or changes, all belong to the protection scope of the present utility model.
