[0021] Example:

[0022] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a single door frame assembly fixture, including two parallel slide rail seats 1 and a first base frame 2 and a second base frame 3 disposed above the two slide rail seats 1. The first base frame 2 is perpendicularly connected to one end of each of the two slide rail seats 1 to ensure the stability of the first base frame 2. The second base frame 3 is slidably connected to the two slide rail seats 1, thereby allowing the second base frame 3 to slide and adjust on the two slide rail seats 1 to adjust the distance between the first base frame 2 and the second base frame 3, so as to facilitate positioning for different types of angle steel. One side of each slide rail seat 1 has multiple first positioning grooves 101 distributed along its length direction. The position of each first positioning groove 101 can be set according to the type of angle steel that is frequently welded. A first positioning plate 4 is rotatably connected to the second base frame 3. The lower part of the first positioning plate 4 is matched and snapped into a first positioning groove 101. When positioning a specific type of angle steel, the second base frame 3 can be quickly slid, and then the lower part of the first positioning plate 4 can be directly snapped into the corresponding first positioning groove 101, thus ensuring the stability of the second base frame 3. The operation is simple and stable.

[0023] One end of the first base frame 2 is slidably connected to a first sliding plate 5, and one end of the second base frame 3 is slidably connected to a second sliding plate 6. The first sliding plate 5 and the second sliding plate 6 are parallel to each other. One end of the second base frame 3 is provided with a plurality of second positioning grooves 301 distributed along its length. The position of each second positioning groove 301 can be set according to the type of angle steel that is frequently welded. The side of the second sliding plate 6 is rotatably connected to a second positioning plate 7. The lower part of the second positioning plate 7 is matched and snapped into a second positioning groove 301. When positioning a specific type of angle steel, the second sliding plate 6 can be slid quickly, and then the lower part of the second positioning plate 7 can be directly snapped into the corresponding second positioning groove 301, which can ensure the stability of the second base frame 3. The operation is simple and stable, and the first sliding plate 5 can be adjusted according to the angle steel positioned by the second sliding plate 6.

[0024] First transverse angle steel positioning components are installed on both the first sliding plate 5 and the second sliding plate 6 to position the first transverse angle steel 19 by means of two first transverse angle steel positioning components; second transverse angle steel positioning components are installed on the other end of the first base frame 2 and the other end of the second base frame 3 to position the second transverse angle steel 20 by means of two second transverse angle steel positioning components; first longitudinal angle steel positioning components are installed on the other end of the first sliding plate 5 and the first base frame 2 to position the first longitudinal angle steel 21 by means of two first longitudinal angle steel positioning components; second longitudinal angle steel positioning components are installed on the other end of the second sliding plate 6 and the second base frame 3 to position the second longitudinal angle steel 22 by means of two second longitudinal angle steel positioning components. The first transverse angle steel 19, the second transverse angle steel 20, the first longitudinal angle steel 21 and the second longitudinal angle steel 22 are quickly assembled into a single door frame to facilitate rapid welding.

[0025] In this invention, the second base frame 3 is slidably connected to two slide rail seats 1, allowing the second base frame 3 to be slidably adjusted on the two slide rail seats 1 to adjust the distance between the first base frame 2 and the second base frame 3. Then, the lower part of the first positioning plate 4 is directly engaged in the corresponding first positioning groove 101 to achieve the positioning of the second base frame 3. Then, the first transverse angle steel positioning component and the second transverse angle steel positioning component can be used to achieve the rapid positioning of the first transverse angle steel 19 and the second transverse angle steel 20. At the same time, the second sliding plate 6 is slidably connected to one end of the second base frame 3, allowing the second sliding plate 6 to slide on the second base frame 3. Then, according to the angle steel model, the lower part of the second positioning plate 7 is directly engaged in the corresponding second positioning groove 301 to ensure the stability of the second base frame 3 and, consequently, the stability of the first sliding plate 5. Then, the first longitudinal angle steel positioning component and the second longitudinal angle steel positioning component can be used to achieve the rapid positioning of the first longitudinal angle steel 21 and the second longitudinal angle steel 22. Thus, the rapid assembly of the single door frame is achieved, thereby ensuring the stability of the frame during welding and the manufacturing quality of the single door frame.

[0026] As a preferred embodiment of this example, it should be further explained that the first positioning plate 4 includes a first vertical positioning part 401 and a first tilting handle part 402.

One end of the first tilting handle part 402 is connected to the first vertical positioning part 401, and the other end of the first tilting handle part 402 is tilted outward from the first positioning groove 101 to facilitate the operation of the first positioning plate 4 through the first tilting handle part 402. When it is necessary to adjust the second base frame 3 to slide along the slide rail seat 1, it is only necessary to move the first tilting handle part 402 so that the lower end of the first vertical positioning part 401 is disengaged from the first positioning groove 101.
