[0018] Beneficial Effects

[0019] The present invention provides a clamping and fixing device for processing aluminum alloy doors and windows. Compared with the prior art, it has the following beneficial effects:

[0020] (1) By setting up a clamping device, the pressure plate is rotated to drive the cutting machine to descend to cut the pipe. By pressing the clamping plate downward, the clamping plate and the fixing plate can cooperate to clamp the pipe, thereby reducing the operation steps and improving the efficiency of pipe fixing. At the same time, the pressure plate is used to press the sliding bar downward to compress the air inside the fixing frame, which not only maintains the pressure of the pipe to improve its stability during cutting, but also offsets and buffers the vibration generated by the cutting through air damping to avoid the problem of reduced cutting accuracy.

[0021] (2) By setting up a feeding assembly, the arc plate is aligned with the fixed plate and the arc groove, and the connecting plate and the push plate are driven to rotate back and forth through a rotating plate and an eccentric rod on one side. The displacement difference during the rotation process can be used to automatically push the pipe through the push plate, thereby realizing automatic loading, avoiding the problem of repeated manual loading, and improving the overall cutting efficiency.

[0022] (3) By setting up a driving unit, the worm is used to rotate with the pressure plate, and through the meshing of the worm and the worm wheel, and the connection between the missing gear and the slide frame, the connecting strip follows the reciprocating motion, and through the eccentric setting of the rotating plate and the pin rod on one side, the rotating plate on the other side drives the push plate to move synchronously, so as to perform automatic loading, thereby improving the overall cutting efficiency.

[0023] (4) By setting up an abutment unit, the push bar is used to follow the rotating plate on one side to perform reciprocating motion, thereby pushing the sliding rod and the piston on one side to move, and the internal gas of the connecting tube enters the inside of the solid sleeve, pressing down the piston inside the solid sleeve, so that the sliding rod on the other side drives the pressure roller and the push plate to approach, so that the pressure roller abuts against the pipe, so as to avoid the pipe from being offset during the pushing process, which affects the continuous cutting of the pipe.

[0024] (5) By setting up a buffer module, when the outer diameter of the pipe is larger than the normal spacing between the pressure roller and the push plate, the pipe abuts against the pressure roller and moves upward, and the air is compressed into the inside of the solid pipe through the piston inside the solid sleeve, thereby increasing the overall volume through the movement of the circular plate to accommodate excess air, thereby achieving buffering when the large outer diameter pipe abuts against the pressure roller, thereby ensuring stable pushing of the pipe.

[0046] Embodiment 4: Based on Embodiment 3, refer to the attached Figure 1 , Attachment Figure 4 ;

[0047] Abutment unit 66 is arranged on the outside of the connecting plate 64, and the abutment unit 66 includes a solid sleeve 661, the outer surface of the solid sleeve 661 is fixedly connected to the outer surface of the arc plate 61, and the interior of the solid sleeve 661 is penetrated and connected with a connecting pipe 663, and the interiors of the connecting pipe 663 and the solid sleeve 661 are filled with high-pressure gas, and the interiors of the solid sleeve 661 and the connecting pipe 663 are movably connected with pistons 664, and the pistons 664 can move by changes in air pressure, and the outer surfaces of the pistons 664 on both sides are fixedly connected with sliding rods 665, and the connection between the sliding rods 665 and the connecting pipe 663 and the solid sleeve 661 is provided with sliding sealing measures, and one end of the sliding rods 665 on both sides is respectively penetrated and slidably connected with the main body of the solid sleeve 661 and the connecting pipe 663, and one end of the sliding rod 665 on one side is fixedly connected with a solid block 666, and the solid block 666 plays the role of connecting support.

[0048] The outer surface of the solid block 666 is embedded with a pressure roller 667 that is rotatably connected. The pressure roller 667 can abut against the top of the pipe and reduce the wear when pushing the material by rolling. The pressure roller 667 is arranged above the arc plate 61, and one end of the other side slide bar 665 is rotatably connected with a push bar 668. The push bar 668 is connected to a rotating plate 69 on one side, so that the pressure roller 667 can move synchronously with the push plate 63 to form an abutment and clamping effect on the pipe, thereby ensuring the stability of the pipe when pushing the material. The body of the push bar 668 is rotatably connected to the outer surface of the pin rod 654.

[0049] By setting up the abutment unit 66, the push bar 668 is used to follow the one side rotating plate 69 to perform reciprocating motion, thereby pushing the one side sliding rod 665 and the piston 664 to move, and the internal gas enters the solid sleeve 661 through the connecting tube 663, pressing down the piston 664 inside the solid sleeve 661, so that the other side sliding rod 665 drives the pressure roller 667 to approach the push plate 63, so that the tube is abutted by the pressure roller 667, so as to avoid the deviation of the tube during the pushing process, which affects the continuous cutting of the tube.

[0050] Embodiment 5: Based on Embodiment 4, refer to the attached Figure 4 , Attachment Figure 5 ;

[0051] A buffer module 662 is provided on the body of the solid sleeve 661, and the buffer module 662 includes a solid tube 6621. One end of the solid tube 6621 is connected to the interior of the solid sleeve 661. A spring rod 6622 is provided inside the solid tube 6621. The elastic force of the spring rod 6622 can offset the air pressure. A circular plate 6623 is fixedly connected to the output end of the spring rod 6622. The circular plate 6623 is made of the same material as the piston 664. The outer surface of the circular plate 6623 is movably connected to the interior of the solid tube 6621. A stop block 6624 is clamped on the outer surface of the circular plate 6623. The stop block 6624 can limit the circular plate 6623 to keep the air pressure inside the solid sleeve 661 and the connecting tube 663 constant. The outer surface of the stop block 6624 is fixedly connected to the interior of the solid tube 6621.

[0052] One end of the spring rod 6622 is fixedly connected to an electromagnet 6625, which is electrically connected to an external control circuit. The outer surface of the electromagnet 6625 is fixedly connected to the inside of the fixed tube 6621. A magnetic ring 6626 is sleeved on the outside of the output end of the spring rod 6622.

The outer surface of the magnetic ring 6626 is fixedly connected to the outer surface of the circular plate 6623.

[0053] By setting up the buffer module 662, when the outer diameter of the tube is larger than the normal spacing between the pressure roller 667 and the push plate 63 after movement, the tube abuts the pressure roller 667 and moves upward, and the air is compressed into the inside of the solid tube 6621 through the piston 664 inside the solid sleeve 661, so that the overall volume is increased through the movement of the circular plate 6623 to accommodate excess air, thereby achieving buffering when the large outer diameter tube abuts to ensure stable pushing of the tube.

[0054] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0055] During operation, the pipe to be cut is placed on the arc plate 61 and the arc groove 4 of the fixing plate 3, and the position to be cut on one side of the pipe is located below the cutting machine 1. Then, the handle 9 is held to rotate the pressing plate 5. The pressing plate 5 contacts the slide bar 11 during rotation and presses the clamping plate 8 downward through the through groove 7 to clamp the pipe. During the movement of the clamping plate 8, the slide column 14 slides inside the connecting groove 15, and the slide block 13 slides inside the fixing groove 12, thereby maintaining the stability of the clamping plate 8. At the same time, the slider 13 stretches the tension spring 17 to facilitate the reset of the clamping plate 8 after it is disengaged from the abutment. As the pressure plate 5 drives the cutting machine 1 to continue to descend to cut the pipe, the pressure plate 5 pushes the slide bar 11 to the inside of the fixed frame 10, so that the high-pressure air inside the fixed frame 10 is compressed by the slide bar 11. On the one hand, the pressure-maintaining effect is achieved to improve the stability of the pipe. On the other hand, the vibration of the cutting machine 1 during cutting is buffered by the effect of air damping, and the stability of the pipe is not affected, thereby improving the cutting accuracy.

[0056] During the rotation of the pressing plate 5, one side of the shaft end drives the worm 658 to rotate synchronously. The worm 658 meshes with the worm wheel 657, so that the rotating shaft 656 drives the missing gear 655 to reciprocate. The missing gear 655 is connected with the tooth groove on the inner wall of the sliding frame 651, so that the sliding frame 651 follows the reciprocating motion, thereby driving the rotating plate 69 on one side to rotate continuously through the connecting bar 653. The rotating plate 69 on one side drives the rotating plate 69 on the other side to follow the rotation through the rotating rod 68. The rotating plate 69 on the other side drives the push plate 63 to rotate through the eccentric rod 610. During the movement of the push plate 63, the displacement difference and the contact with the pipe push the pipe forward, and the pushing distance is preset to be the length to be cut.

[0057] During the rotation of the rotating plate 69 on one side, the push bar 668 is driven by the action of the pin 654, so that the sliding rod 665 on one side drives the piston 664 to slide into the connecting tube 663, thereby pushing the gas inside the connecting tube 663 into the solid sleeve 661, and the internal air pressure of the solid sleeve 661 increases, thereby pushing the piston 664 on the other side to slide inside, and through the action of the sliding rod 665 on the other side and the solid block 666, the pressure roller 667 is driven to approach the arc plate 61, so that the pipe is clamped during the pushing process through the interaction with the push plate 63, so as to improve the stability of the pipe movement, and the rolling of the pressure roller 667 facilitates the forward movement of the pipe;

[0058] When the pressure roller 667 descends and contacts the pipe, and if the outer diameter of the pipe is larger than a predetermined size, the pipe abuts the pressure roller 667 to pull the piston 664 inside the solid sleeve 661 upward, thereby compressing the air inside the solid sleeve 661 into the solid tube 6621, and the circular plate 6623 moves under the action of air pressure and compresses the output end of the spring rod 6622. At the same time, when the outer diameter of the pipe is smaller than a predetermined size, the output end of the spring rod 6622 pushes the circular plate 6623 to move, compressing the air inside the solid tube 6621 into the solid sleeve 661, so that the pressure roller 667 continues to descend to contact the pipe. In this process, the movement of the circular plate 6623 is limited by the abutment 6624, thereby limiting the movement of the pressure roller 667. In the movement of the circular plate 6623, the electromagnet 6625 adjusts the elastic damping effect of the spring rod 6622 through the magnetic repulsion and attraction with the magnetic ring 6626.
