When the locking rod 7 is screwed, the positioning clamping plate 6 can be pushed downward. When the aluminum alloy frame needs to be straightened, a part of the aluminum alloy frame is placed in the placement slot 4, and then the aluminum alloy frame is pressed down by the positioning clamping plate 6. At this time, the aluminum box into the frame is in a stable state, and the positioning clamping plate 6 and the locking rod 7 form a positioning assembly;

[0033] The positioning splint 6 includes a fixed splint 8 and a displacement splint 9. A through hole is provided on the fixed splint 8, and the lower end of the locking rod 7 passes through the through hole. An anti-slip disk is fixed to the lower end of the locking rod 7.

A rail groove is provided on the fixed splint 8, and the rail groove is located on the lower surface of the fixed splint 8. A slider is fixed on the upper surface of the displacement splint 9, so that the displacement splint 9 can be moved from the positioning clamp 5 to the placement slot 4. At this time, the displacement splint 9 is located above the aluminum alloy frame.

[0034] An extension support plate 11 is arranged on the positioning seat 2, and the upper surface of the extension support plate 11 is flush with the bottom surface of the placement slot 4. A horizontally extending hanger 12 is connected to the positioning seat 2, and the hanger 12 is located above the extension support plate 11. The hanger 12 is a door-shaped frame body, and a rotatable twisting arm 13 passes through the hanger 12. After the twisting arm 13 rotates, the twisting arm 13 moves vertically. A pressing plate 14 is arranged below the twisting arm 13, and the pressing plate 14 is connected to a support arm group fixed on the extension support plate 11.

The pressure plate 14 and the twisting arm 13 form a pressure assembly. At this time, the other part of the aluminum alloy frame is located on the extension support plate 11. Initially, the pressure plate 14 is in an inclined state. When the twisting arm 13 rotates and moves downward, the lower end of the twisting arm 13 applies pressure to the pressure plate 14, gradually changing the pressure plate 14 from an inclined state to a horizontal state, thereby straightening the aluminum alloy frame from a bent state through the cooperation of the positioning assembly and the pressure assembly;

[0035] The support arm group includes a positioning arm group and a limiting arm group. When the aluminum alloy frame is straightened by the pressing plate 14, the positioning arm group locks one end of the pressing plate 14. At this time, the other end of the pressing plate 14 is slidably connected to the limiting arm group. The support arm group consists of two positioning support arms 15. The pressing plate 14 is located between the two positioning support arms 15. Each positioning support arm 15 is provided with a waist-shaped opening 16 extending vertically, and the lower end of each positioning support arm 15 is fixed to the extension support plate 11.

[0036] See also Figures 7 and 8As shown, the locking member 17 includes a sliding plate 18 that can slide vertically in the waist-shaped opening 16. A sliding groove extending along the length direction of the waist-shaped opening 16 is provided on the inner side wall. The edge of the sliding plate 18 fits in the sliding groove. The sliding plate 18 is in the shape of a long strip. An axial head rod 19 passes through the upper end of the sliding plate 18. The axial head rod 19 is fixed on the pressure plate 14.

The threaded shaft 20 is vertically fixed to the sliding plate 18, and a locking plate 21 is screwed on the threaded shaft 20. The locking plate 21 is located outside the waist-shaped opening 16. The sliding plate 18 can be moved downward until one end of the pressing plate 14 contacts the aluminum alloy frame, and then the locking plate 21 is tightened to lock the horizontal height of one end of the pressing plate 14. The end of the pressing plate 14 that is locked at the horizontal height is the locking end.

[0038] For example, a strip-shaped limit groove 25 is provided on the side of the pressing plate 14, and the limit groove 25 extends along the length direction of the pressing plate 14. The inner end of the sliding shaft 24 is fitted in the limit groove 25, and two anti-slip plates are fixed on the sliding shaft 24. The limit plate 22 is located between the two anti-slip plates. When the movable end of the pressing plate 14 moves, the sliding shaft 24 moves in the limit groove 25 and the strip-shaped notch 23 at the same time. After the movable end of the pressing plate 14 is thrust by the screwing arm 13, the movable end of the pressing plate 14 can be moved downward. At this time, the aluminum alloy frame is clamped by the pressing plate 14 and the extending support plate 11, thereby realizing the straightening of the aluminum alloy frame. Both ends of the pressing plate 14 are arc-shaped surfaces, which prevents the pressing plate 14 from damaging the surface of the aluminum alloy frame when it moves.

[0039] If the aluminum alloy frame is not a flat frame, after straightening it, the straightened part is still not flat. For example, the existing light box aluminum alloy frame is mostly composed of an outer frame slat 26 and an inner frame slat 27, and the outer frame slat 26 and the inner frame slat 27 are butted together by a partition bar 28. At this time, there is a gap between the outer frame slat 26 and the inner frame slat 27. After the aluminum alloy frame is straightened from a bent state, its bent part will still be uneven, such as Figure 1 As shown;

[0040] Therefore, in the present application, a slidable pressing assembly is connected to the extension support plate 11, and the pressing assembly is connected to the positioning seat 2 through a horizontal push rod 29. The horizontal push rod 29 is an electric push rod. When the electric push rod is extended or shortened, the pressing assembly is driven to move in the length direction of the aluminum alloy frame plate, and the pressing assembly flattens the aluminum alloy frame plate.

[0042] The flat pressing group includes a cylindrical guide rod 36 fixed in the notch, the guide rod is arranged vertically, and an upper pressing part 37, a middle supporting part 38 and a lower pressing part 39 are arranged on the guide rod 36. The guide rod 36 simultaneously penetrates the upper pressing part 37, the middle supporting part 38 and the lower pressing part 39, and a lower pressing plate 40 sleeved on the guide rod 36 is arranged above the lower pressing part 39. A middle tray 41 and an upper pressing plate 42 are also arranged on the guide rod 36. The middle tray 41 is located below the middle supporting part 38, and the upper pressing plate 42 is located above the upper pressing part 37.

The flap 34 is vertical in the vertical plane. When the flap 34 is turned over to contact the standing plate 33, the flap 34 and the standing plate 33 are connected by bolts, and the lower pressing portion 39 and the middle supporting portion 38 enter between the outer frame slats 26 and the inner frame slats 27. At this time, the lower pressing portion 39 is located above the outer frame slats 26, and the middle supporting portion 38 is located below the inner frame slats, but the upper pressing portion 37 is located above the inner frame slats 27. At this time, the lower pressing portion 39 and the extended supporting plate 11 clamp the outer frame slats 26, and the middle supporting portion 38 and the upper pressing portion 37 clamp the inner frame slats 27. When the upper pressing portion 37, the middle supporting portion 38 and the lower pressing portion 39 move with the slide 30 at the same time, the outer frame slats and the inner frame slats on the aluminum alloy frame plate are leveled;

[0043] The upper pressing part 37, the middle supporting part 38 and the lower pressing part 39 have the same structure, and all include a horizontal arm 43 extending horizontally. The horizontal arm 43 is provided with a channel for passing the guide rod 36. A convex strip 44 is fixed on the inner wall of the channel, and a vertically extending strip groove is provided on the outer wall of the guide rod 36. The convex strip 44 is located in the strip groove, so that the horizontal arm 43 cannot rotate around the guide rod 36. A pressure roller 45 is sleeved on the horizontal arm 43.
