DETAILED DESCRIPTION

[0026] The utility model will be further explained in connection with the drawings and examples, and the mode of the utility model includes but is not limited to the following examples.

[0027] Example 1:

[0028] As Figures 1-4As shown, the steel-concrete movable threshold protective airtight door frame processing device provided by this utility model includes: a mounting frame 1, a support plate 2 mounted on the mounting frame 1, four clamping mechanisms and a linkage mechanism on the support plate 2, the four clamping mechanisms being respectively located in the front, back, left, and right directions of the support plate 2, clamping the top, bottom, left, and right sides of the door frame respectively, the clamping mechanism including a positioning plate 3 on the outer side of the door frame and a pressing plate 4 on the inner side of the door frame, the pressing plate 4 being slidably connected to the support plate 2, two of the four pressing plates 4 moving laterally and the other two moving longitudinally, the pressing plates 4 pressing the door frame from the inside, fixing the door frame inside the positioning plate 3, the linkage mechanism including a rotating plate 5 rotatably mounted at the center of the support plate 2, the rotating plate 5 being equipped with four linkage components of different lengths and adjustable lengths. 6. The two ends of the linkage 6 are rotatably connected to the extrusion plate 4 and the rotating plate 5 respectively. A rotary motor is installed at the bottom of the support plate 2. The rotary motor is connected to the rotating plate 5 and can drive the rotating plate 5 to rotate. In use, the door frame material of the steel-concrete movable threshold protective airtight door is placed on the support plate 2 in sequence. The outer side of the door frame material is attached to the positioning plate 3. The corners are spliced ​​and combined to form the door frame. Then, the rotary motor is started to drive the rotating plate 5 to rotate, which in turn causes the linkage 6 to swing and drives the extrusion plate 4 to move towards the adjacent positioning plate 3 until the extrusion plate 4 is pressed against the inner side of the door frame material to fix the door frame material. Then welding can begin. After welding is completed, the rotary motor drives the rotating plate 5 to rotate in the opposite direction, so that the extrusion plate 4 leaves the welded door frame, making it easy to remove the door frame.

[0029] By setting up an installation frame 1, a support plate 2, a positioning plate 3, and an extrusion plate 4, and setting up a linkage mechanism including a rotating plate 5 and four linkage components 6, the four extrusion plates 4 can be linked together. The four extrusion plates 4 can simultaneously extrude or release the door frame, quickly completing the fixing and loosening process of the door frame, thereby facilitating the loading and unloading of the door frame and improving processing efficiency.

[0030] Example 2:

[0031] like Figures 2-3 As shown, in this embodiment, a T-shaped guide strip 7 is installed at the bottom of the extrusion plate 4. A total of four guide grooves 8, one horizontal and one vertical, are provided on the support plate 2. The guide strip 7 is inserted into the guide groove 8 and can slide along the guide groove 8. When in use, when the linkage 6 pushes or pulls the extrusion plate 4 to move, the extrusion plate 4 always moves along the direction of the guide groove 8, so that the extrusion plate 4 can move stably and its outer side and inner side are always parallel to the corresponding positioning plate 3.

[0032] By setting guide bars 7 and guide grooves 8, the movement direction of the extrusion plate 4 can be easily guided.

[0033] Example 3:

[0034] like Figure 1 and Figure 4As shown, the linkage 6 includes an adjusting screw 9, a first threaded tube 10, and a second threaded tube 11. The two ends of the adjusting screw 9 are connected to the first threaded tube 10 and the second threaded tube 11, respectively. The threads of the first threaded tube 10 and the second threaded tube 11 have opposite directions. To suit the length and width of the door frame, the lengths of the adjusting screw 9, the first threaded tube 10, and the second threaded tube 11 can be selected as needed. The ends of the first threaded tube 10 and the second threaded tube 11 that are far apart from each other are rotatably connected to the connecting lug 12 on the pressing plate 4 and the rotating plate 5, respectively. In use, after the rotating plate 5 is rotated at a certain angle, check the pressing force between the pressing plate 4 and the inner side of the door frame. If the force is too small, rotate the adjusting screw 9 to make the first threaded tube 10 and the second threaded tube 11 move away from each other, thereby making the pressing plate 4 move closer to the door frame and press until it is difficult to rotate the adjusting screw 9 manually. Check the four pressing plates 4 in turn and make appropriate adjustments so that the four pressing plates 4 can press the inner side of the door frame with appropriate force, which facilitates the fixing and welding of the door frame. Similarly, adjustments can be made to accommodate the fixing of door frames of different sizes.

[0035] The length can be easily adjusted by setting up a linkage 6 that includes an adjusting screw 9, a first threaded tube 10, and a second threaded tube 11.

[0036] Example 4:

[0037] like Figure 3 As shown, a pad 13 is installed on the side of the extrusion plate 4 facing the adjacent positioning plate 3. The pad 13 is made of rubber material. When in use, the extrusion plate 4 is extruding the inside of the door frame. The pad 13 can buffer the pressure through deformation to avoid crushing, thereby improving the processing quality of the door frame. With the stroke of the four extrusion plates 4 remaining unchanged, the deformable pad 13 can prevent the problem that some extrusion plates 4 cannot effectively extrude and fix the door frame due to deviations in material specifications and cutting accuracy.

[0038] By installing a pad 13 on one side of the extrusion plate 4, the processing quality of the door frame can be improved, and the fixing effect of the door frame can be enhanced.

[0039] Example 5:

[0040] like Figure 1 As shown, a flip motor 14 is installed on one side of the mounting bracket 1. The flip motor 14 is connected to the support plate 2 and is used to drive the support plate 2 to flip. When in use, the flip motor 14 is started, which can make the support plate 2 flip 90 degrees or 180 degrees, thereby facilitating vertical welding or welding to the back of the door frame.

[0041] By installing a flip motor 14 on one side of the mounting bracket 1, the welding of the door frame can be facilitated.

[0042] Example 6:

[0043] likeFigure 1 As shown, the screw-nut pair 15 is installed between the support plate 2 and the positioning plate 3. In use, the screw-nut pair 15 can drive the positioning plate 3 to move outward or inward, thereby adapting to the welding of door frames of different specifications.

[0044] By installing the screw-nut pair 15 between the support plate 2 and the positioning plate 3, the position of the positioning plate 3 can be conveniently adjusted to adapt to the welding of door frames of different specifications.

[0045] Working principle: In use, the door frame materials of the steel-concrete active door sill protection sealed door are placed on the support plate 2 in sequence, the outer side of the door frame materials is attached to the positioning plate 3, the corners are spliced and combined into a door frame, then the rotating motor is started to drive the rotating plate 5 to rotate, thereby driving the linkage 6 to swing and driving the pressing plate 4 to move to the adjacent positioning plate 3, until the pressing plate 4 is pressed on the inner side of the door frame materials, so that the door frame materials are fixed, then the welding can be started, after the welding is completed, the rotating motor drives the rotating plate 5 to rotate reversely, so that the pressing plate 4 is separated from the welded door frame, thereby facilitating the removal of the door frame.
