[0015] The utility model has the following beneficial effects:

[0016] 1. In the utility model, when the motor is started, the motor drives the turntable to rotate. The turntable drives the limit rod to move through the limit groove. The limit rod drives the first connecting plate to slide outside the first slider. At the same time, the first connecting plate drives the fixing clip to move towards the center of the fixing plate through the second connecting plate, so that the fixing clip moves closer to the middle to clamp and fix the square rectangular tube, which can ensure that the workpiece will not shake or fall off during the flipping process of the square rectangular tube, thus ensuring the stability of the square rectangular tube flipping frame.

[0017] 2. In the utility model, when the cylinder is started, the cylinder drives the rack to move. The movement of the rack drives the gear to rotate. The gear drives the mounting frame to rotate through the first connecting rod, and the mounting frame drives the fixing plate to rotate, which can quickly flip the square rectangular tube to another state, reducing the time and improving the working efficiency of the square rectangular tube flipping frame.

Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figures 1-3 , an embodiment provided by the present invention: A rectangular tube turnover frame includes a first support plate 2 and a second support plate 3. An electric telescopic rod 25 is connected between the first support plate 2 and the second support plate 3. On the side where the first support plate 2 and the second support plate 3 are close to each other, mounting frames 1 are connected. There are two groups of mounting frames 1. One end of a group of mounting frames 1 is fixedly connected to a second connecting rod 5, and one end of the other group of mounting frames 1 is fixedly connected to a first connecting rod 4. One ends of the two groups of mounting frames 1 far from the second support plate 3 and the first support plate 2 are fixedly connected to a fixed plate 6. A motor 7 is fixedly connected inside the mounting frame 1. The output shaft of the motor 7 passes through the fixed plate 6 and is fixedly connected to a turntable 8. A plurality of limiting grooves 9 are opened inside the turntable 8. A limiting rod 10 is slidably connected inside the limiting groove 9. One end of the limiting rod 10 is fixedly connected to a first connecting plate 11. A first sliding groove 12 is opened inside the first connecting plate 11. A first slider 13 is slidably connected inside the first sliding groove 12. One end of the first slider 13 is fixedly connected to the front end of the fixed plate 6. A second connecting plate 14 is fixedly connected to the front end of the first connecting plate 11. One end of the second connecting plate 14 is fixedly connected to a fixed clamp 15.

[0025] One end of the first connecting rod 4 rotates inside the first support plate 2. One end of the first connecting rod 4 passes through the first support plate 2 and is fixedly connected with a gear 17. A connecting frame 18 is fixedly connected to the outside of the first support plate 2. One end of the connecting frame 18 is fixedly connected with a third connecting plate 19. One end of the third connecting plate 19 is fixedly connected with a support frame 20. A cylinder 21 is fixedly connected inside the support frame 20. The output end of the cylinder 21 is fixedly connected with a rack 22. The top of the rack 22 is meshed and connected with the gear 17. A second chute 23 is formed inside the third connecting plate 19. A second slider 24 is slidably connected inside the second chute 23. The top of the second slider 24 is fixedly connected to the bottom of the rack 22, which can improve the stability of the gear 22 during movement. The use of the electric telescopic rod 25 can be adjusted according to the length of the square tube, improving flexibility. Bases 26 are fixedly connected to the bottoms of both the first support plate 2 and the second support plate 3. Brake universal wheels 27 are connected to the bottoms of the bases 26. Anti-slip pads 16 are fixedly connected to the inner sides of the fixed clamps 15 to increase friction. Multiple groups of anti-slip pads 16 are provided. The anti-slip pads 16 are made of rubber material and are not easily deformed.

[0026] Working principle: After moving the flipping frame to a suitable position, fix the brake of one group of brake universal wheels 27, and start the electric telescopic rod 25. The distance between the first support plate 2 and the second support plate 3 can be adjusted according to the length of the square tube. Then, place both ends of the square tube inside the fixed clamps 15, and start the motor 7. The motor 7 drives the turntable 8 to rotate. The turntable 8 drives the limiting rod 10 to move through the limiting groove 9. The limiting rod 10 drives the first connecting plate 11 to slide outside the first slider 13. At the same time, the first connecting plate 11 drives the fixed clamp 15 to move towards the center of the fixed plate 6 through the second connecting plate 14, clamping and fixing the square tube to prevent the square tube from slipping during rotation. Finally, start the cylinder 21. The cylinder 21 drives the rack 22 to move. When the rack 22 moves, it drives the gear 17 to rotate. The gear 17 drives the mounting frame 1 to rotate through the first connecting rod 4. The mounting frame 1 drives the fixed plate 6 to rotate. The fixed plate 6 drives the square tube to rotate. At the same time, the square tube can drive the second connecting rod 5 to rotate inside the second support plate 3 through the fixed plate 6 and the mounting frame 1, which can quickly flip the square tube and improve work efficiency.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
