Detailed Embodiment

[0018] The following further describes the specific embodiments of the present invention with reference to the drawings.

[0019] As Figure 1-6 shown, a welding tooling for the reinforcing rib inside an elevator door panel includes an operating table 3. A placement cavity 4 is arranged on the upper surface of the operating table 3. An accommodation cavity 5 is arranged inside the operating table 3 and on one side of the placement cavity 4. A guide rod 6 is slidably connected inside the accommodation cavity 5. A limiting block 7 is arranged at one end of the guide rod 6. A limiting groove is arranged at the other end of the guide rod 6, and the limiting groove is located inside the placement cavity 4. A spring 9 is sleeved on the guide rod 6, and the spring 9 is located between the placement cavity 4 and the accommodation cavity 5. Fixed rails 10 are respectively arranged on both sides of the operating table 3. It further includes two groups of limiting components. Each limiting component includes two sliders 11 that can slide along the fixed rails 10. The two sliders 11 are connected by a main shaft 12. Two swing rods 13 are symmetrically arranged on the main shaft 12. The swing rod 13 can only rotate on the main shaft 12 and cannot move. A limiting rod 14 is arranged at the end of the swing rod 13 far from the main shaft 12. A compressible pressing block 15 is arranged on the outer surface of the other end of the main shaft 12.

[0020] Before placing the elevator door panel 1 into the placement cavity 4, refer to Figure 1 and Figure 4 , first, through the cooperation of the slider 11 and the fixed rail 10, move the main shaft 12 to a position outside the upper part of the placement cavity 4, and the two main shafts 12 are respectively located on both sides of the placement cavity 4. At the same time, flip the swing rod 13 onto the operating table 3 to avoid the swing rod 13 occupying the internal space of the placement cavity 4. Then, the elevator door panel 1 can be placed into the placement cavity 4. When placing, first insert the short board of the elevator door panel 1 into the placement cavity 4, and then make it abut against the placement groove 8 through this short side, and continuously push the placement groove 8 to move, so that the spring 9 is continuously compressed. When the elevator door panel 1 can be completely placed into the placement cavity 4, directly place the elevator door panel 1 at the bottom of the placement cavity 4, and clamp the elevator door panel 1 under the action of the spring 9 to complete the positioning of the elevator door panel 1. The elevator door panel 1 can only move along the length direction of the placement cavity 4 inside the placement cavity 4.

[0021] After completing the placement of the elevator door panel 1, at this time, the reinforcing rib 2 needs to be placed on the elevator door panel 1. Refer to Figure 4 , Figure 5 and Figure 6 , first flip the swing rod 13. At this time, the position of the main shaft 12 remains unchanged. After the swing rod 13 is flipped, the swing rod 13 is located above the elevator door panel 1. At the same time, the limiting rod 14 enters the inside of the elevator door panel 1. When all the limiting rods 14 are flipped above the elevator door panel 1, place one of the reinforcing ribs 2 between the four limiting rods 14, and then push the reinforcing rib 2 to move until the reinforcing rib 2 abuts against the two limiting rods 14 on the same side at the same time. Then place the other reinforcing rib 2 into the inside of the elevator door panel 1, and then push the reinforcing rib 2 in another direction until the reinforcing rib 2 abuts against the other two limiting rods 14 at the same time. The positions where the two reinforcing ribs 2 are located at this time are the positions where they are to be welded to the elevator door panel 1. To prevent the reinforcing rib 2 from moving during welding, flip the swing rod 13. After the swing rod 13 is flipped, the pressing block 15 at one end of the swing rod 13 squeezes the reinforcing rib 2, and the pressing block 15 is compressed. When all four swing rods 13 are flipped, the two reinforcing ribs 2 are all pressed tightly on the elevator door panel 1, so that the reinforcing rib 2 can be welded to the elevator door panel 1.

[0022] After pressing the reinforcing rib 2 through the pressing block 15, the limiting rod 14 at the other end of the swing rod 13 is flipped to a position outside the placement cavity 4 to reduce the obstruction of the limiting rod 14 to the reinforcing rib 2 and the elevator door panel 1, facilitating the staff to weld the reinforcing rib 2 to the elevator door panel 1.

[0023] After completing the welding of the reinforcing rib 2 and the elevator door panel 1, reverse the swing rod 13, and move the main shaft 12, the swing rod 13, and the limit rod 14 away from the placement cavity 4. Then, the elevator door panel 1 can be taken out of the placement cavity 4 through the reinforcing rib 2, or the elevator door panel 1 in the placement cavity 4 can be transferred out by an adsorption device such as a vacuum suction cup.

[0024] Furthermore, both ends of the fixed rail 10 are closed to prevent the slider 11 from sliding out of the fixed rail 10.

[0025] Furthermore, a positioning plate 16 is provided on the outer surface of the fixed rail 10. The positioning plate 16 is used to accurately position the position of the main shaft 12. When the slider 11 contacts the main shaft 12, the limit rod 14 can stably flip to a position outside the placement cavity 4 after flipping, thereby improving the efficiency of pressing the reinforcing rib 2.

[0026] Furthermore, the welding position of the reinforcing rib 2 and the elevator door panel 1 is located on the side of the reinforcing rib 2. When the reinforcing rib 2 abuts against the limit rod 14, the swing rod 13 is located directly above the reinforcing rib 2 to reduce the shielding of the welding position of the reinforcing rib 2 and the elevator door panel 1 by the swing rod 13.

[0027] Furthermore, a chamfer is provided at the upper opening of the placement cavity 4 to facilitate the placement of the elevator door panel 1 into the placement cavity 4.

[0028] When the device is in use, the limit rod 14 and the pressing block 15 for positioning and fixing the reinforcing rib 2 are both provided on the swing rod 13. By controlling the flipping of the swing rod 13, rapid switching between the positioning and fixing of the reinforcing rib 2 can be achieved, reducing the structural complexity of the welding tooling and improving the convenience of placing the reinforcing rib 2.
