[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application embodiment discloses a clamp for welding a rectangular container. Figure 1-5 The rectangular container welding fixture comprises a supporting main rod 1, and supporting sub-rods 2 are fixed at both ends of the supporting main rod 1. The supporting main rod 1 comprises a first rod 5 and a second rod 6, and the length directions of the first rod 5 and the second rod 6 are parallel to each other. In the present embodiment, the first rod 5 and the second rod 6 are both rectangular, and a sliding hole 7 is opened at the end of the first rod 5. The cross-sectional shape of the sliding hole 7 is rectangular, and the second rod 6 is penetrated in the sliding hole 7. At the same time, the second rod 6 is slidably connected to the inner side wall of the sliding hole 7. The position of the second rod 6 can be adjusted by controlling the sliding of the second rod 6 in the sliding hole 7, thereby adjusting the main body length of the supporting main rod 1, so as to adapt to containers of different sizes. The two supporting sub-rods 2 are respectively fixed to the side walls of the first rod 5 and the second rod 6 by an integral molding method, and the two supporting sub-rods 2 are parallel to each other.

[0035] Reference Figure 1-5A supporting portion 3 is provided on the side wall of one supporting auxiliary rod 2, and a clamping portion 4 is provided on the other supporting auxiliary rod 2. The supporting portion 3 is used to support the inside of the container, thereby clamping the container from the inside of the container; the clamping portion 4 is used to clamp the container from the outside of the container, thereby fixing the position of the container.

[0036] Reference Figure 1-5 The tightening part 3 includes a first mounting plate 8, which is rotatably connected to the supporting sub-rod 2 through a rotating shaft. A plurality of tightening rods 9 are rotatably connected to the first mounting plate 8 through a rotating shaft. In the present embodiment, there are four tightening rods 9, which correspond to the inner side walls of the container. The rotation of the tightening rod 9 can be controlled by a motor, and the motor shaft key is connected to the tightening rod 9 shaft, thereby driving the tightening rod 9 to rotate; the rotation of the tightening rod 9 can also be controlled by an electric cylinder, and the driving part is rotatably connected to the middle part of the tightening rod 9, and the driving part is rotatably connected to the end of the electric cylinder piston rod, and the tightening rod 9 can be driven to rotate by the movement of the electric cylinder piston rod; a first anti-slip layer 10 is fixed to the end of the tightening rod 9 by bonding, and the first anti-slip layer 10 is made of rubber. The first anti-slip layer 10 is used to increase the friction between the tightening rod 9 and the inner wall of the container, thereby reducing the possibility of changes in the position of the container.

[0037] Reference Figure 1-5 The clamping portion 4 includes a second mounting disk 11, which is rotatably connected to the side wall of the supporting auxiliary rod 2 through a rotating shaft. The end surface of the second mounting disk 11 is rotatably connected to a plurality of clamping rods 12 through a rotating shaft. The clamping rod 12 can rotate on the end surface of the second mounting disk 11, and the method of controlling the rotation of the clamping rod 12 is the same as the method of controlling the rotation of the support rod 9. The clamping rod 12 is in a "C" shape, and the end of the clamping rod 12 away from its own rotating shaft is fixed with a clamping block 13 by an integral molding manner. The clamping block 13 is arranged in a "V" shape, and the end of the clamping block 13 is fixed with a second anti-slip layer 14 by bonding. The second anti-slip layer 14 is made of rubber. The second anti-slip layer 14 is used to enhance the friction between the clamping block 13 and the side wall of the container, thereby reducing the possibility of displacement of the container position.

The connecting hole 16 is coaxially arranged with the sliding hole 7 and the connecting hole 16 is connected to the sliding hole 7. The piston rod of the driving electric cylinder 15 is penetrated through the connecting hole 16 and the piston rod of the driving electric cylinder 15 is fixed to the end of the second rod 6 by bolt fixing. The driving electric cylinder 15 is used to drive the second rod 6 to slide in the sliding hole 7, so as to control the position of the second rod 6; the side walls of the two supporting auxiliary rods 2 are fixed with control motors 17, and the control motors 17 are used to drive the tightening part 3 and the clamping part 4 to rotate. The rotating shafts of the two control motors 17 are respectively keyed to the first mounting plate 8 and the second mounting plate 11. At the same time, the two control motors 17 run synchronously, which is convenient for driving the container to rotate.
