DETAILED DESCRIPTION

[0020] like Figure 1 and Figure 2 As shown, a civil air defense door frame welding frame includes a placement frame 1, and two adjacent outer walls of one side corner of the placement frame 1 are provided with a slide groove 2, and also include a bearing plate 3, a limiting mechanism 4 and a pressing mechanism 5. The limiting mechanism 4 is arranged at the bottom center of the placement frame 1, and the pressing mechanism 5 is slidably arranged in the slide groove 2. The bearing plate 3 can be rotatably arranged at the upper center of the placement frame 1. The upper bearing plate 3 of the placement frame 1 is used to support the civil air defense door so that the civil air defense door can be rotated to adjust the direction. The limiting mechanism 4 is used to limit the corner of one side of the civil air defense door, which can be used as a reference surface for batch processing. The pressing mechanism 5 is used to make the door frame close to the outer wall of the civil air defense door, which is convenient for welding processing.

[0021] like Figure 2-4 As shown, in order to realize the limiting placement of civil defense doors of different thicknesses, the limiting mechanism 4 includes a limiting tube 6, a cylinder 7, a connecting plate 8, a connecting rod 9, a connecting frame 10 and a buckle assembly 11. The limiting tube 6 is arranged at the center of the bottom wall of the placement frame 1, and a strip hole 12 is opened in the middle of the side wall of the limiting tube 6. The strip holes 12 are symmetrically arranged in pairs. The cylinder 7 is arranged on the inner bottom wall of the limiting tube 6, and the connecting plate 8 is arranged at the telescopic end of the cylinder 7. The connecting plate 8 is located in the limiting tube 6 and fits with the inner wall of the limiting tube 6. One end of the connecting rod 9 is arranged in the middle of the outer wall of the connecting plate 8, and the connecting rod 9 is slidably arranged in the strip hole 12. The connecting rods 9 are symmetrically arranged in pairs, and the connecting frame 10 is arranged at the other end of the symmetrical connecting rods 9. The buckle assembly 11 is arranged at the corner of the connecting frame 10 away from the side of the edge pressing assembly. The cylinder 17 pushes the connecting rod 9 up and down in the limiting tube 6, and at the same time drives the outer connecting rod 9 and the connecting frame 10 outside the connecting rod 9 to move up and down, so as to realize the height adjustment of the buckle assembly 11;

[0022] In order to press and limit a corner of the civil defense door, the snap-fit ​​assembly 11 includes a cylinder three 21 and a limit plate 22. The cylinder three 21 is arranged on the inner wall of the connecting frame 10. The cylinder three 21 is located on the adjacent two side walls of the connecting frame 10 at an angle away from the slide groove 2. The cylinder three 21 is vertically distributed. The telescopic end of the cylinder three 21 passes through the connecting frame 10 and is slidably arranged in the limit frame. The limit plate 22 is arranged at the telescopic end of the cylinder three 21. The cylinder three 21 moves up and down with the support frame. The left and right directions of the limit plate 22 are adjusted by telescoping the telescopic end of the cylinder three 21, so that the limit plate 22 can snap fit the adjacent outer wall of a corner of the civil defense door.

[0023] As shown in the figure, in order to achieve the door frame fitting with the outer wall of the civil air defense door, the edge pressing mechanism 5 includes a moving plate 13, a second cylinder 14, a push plate 15 and a pressing assembly 16. The moving plate 13 is slidably arranged in the slide groove 2, the second cylinder 14 is arranged at the end of the moving plate 13 away from the slide groove 2, the push plate 15 is arranged at the telescopic end of the cylinder, and the pressing assembly 16 penetrates the push plate 15 and is movably connected in the push plate 15. The moving plate 13 moves in the slide groove 2 and can be synchronously moved along one side direction of the outer wall of the placement rack 1 with the welding manipulator. The second cylinder 14 telescopically adjusts the distance between the pressing assembly 16 and the placement rack 1, so that the pressing assembly 16 can meet the requirements of civil air defense doors of different sizes;

[0024] The pressing assembly 16 includes a stud 17, a connecting block 18 and a roller 19. One end of the stud 17 passes through the push plate 15 from top to bottom and is threadedly connected to the push plate 15. The connecting block 18 is rotatably arranged at the upper end of the stud 17, and the roller 19 is rotatably arranged on the outer wall of the connecting block 18. The two end faces of the roller 19 are staggered with different diameters. A handle 20 is provided at the bottom of the stud 17. By turning the handle 20, the stud 17 is rotated in the push plate 15, and the distance between the connecting block 18 and the push plate 15 is adjusted so that the roller 19 can be pressed on the upper corners of civil air defense doors of different thicknesses. The steps formed by the different diameters of the two end faces of the roller 19 are used to press the edge of the door frame to push the door frame to fit the outer wall of the civil air defense door. The roller 19 rotates with the movement of the movable plate 13, so that the welding manipulator is located between the symmetrical rollers 19, thereby increasing the welding effect of the door frame fitting the outer wall of the civil air defense door.

[0025] Among them, the slide groove 2 is set in a T shape, the limit plate is set in an inverted L shape, and support legs 23 are provided at the bottom corners of the placement rack 1. The support legs 23 are symmetrically arranged in pairs. The support legs 23 increase the bottom height of the placement rack 1 and increase the stability of the placement rack 1. The movable plate 13 matches the slide groove 2 to prevent the movable plate 13 from tilting during movement. After the position of the limit plate is adjusted, the two adjacent outer side walls of a corner of the civil defense door can be buckled, pressed, supported and limited.

[0026] When in use, the operator can first place the civil air defense door on the carrier plate 3, drive the cylinder 1 7 to adjust the height of the connecting frame 10 up and down, and make the cylinder 3 21 push out the limit plate 22, buckle and press it on the two adjacent outer walls of a corner of the civil air defense door. The limit plate 22 can be used as the positioning reference of the civil air defense door in the subsequent welding process, reducing the time of the welding robot for the next welding point alignment;

[0027] After the civil air defense door is limited, the door frame is fitted against the outer wall of the civil air defense door, and the driving cylinder 2 14 is contracted, so that the moving wheel is close to the door frame and pushes the door frame to fit against the outer wall of the civil air defense door. The roller 19 presses the edge of the door frame using the steps formed by the different diameters of the two end faces. By turning the handle 20, the distance between the connecting block 18 and the push plate 15 can be adjusted, so that the roller 19 can press the upper corners of civil air defense doors of different thicknesses. The roller 19 rotates with the movement of the moving plate 13, so that the welding manipulator is between the symmetrical rollers 19, thereby increasing the welding effect of the door frame fitting against the outer wall of the civil air defense door.
