A quick-connect automatic coupling structure for sizing machine equipment

Abstract

This utility model discloses a quick-connecting automatic coupling structure for sizing machines. The key technical features are: a first connecting cylinder with a first mounting head fixedly installed at one end, and a second mounting cylinder with a second mounting head fixedly installed at one end of the other end. By setting a mounting ring, during connection, the connecting block on the mounting ring is first inserted into the clamping interface. When the connecting block is inserted into the clamping interface, it squeezes the pressure plate inside the interface, compressing the spring in the pressure groove. When the connecting block is fully inserted into the clamping interface, the pressure plate flips upwards due to the spring, and the flipped pressure plate is locked inside the groove on the connecting block. At this point, the connecting block is fixed inside the clamping interface, thus completing the connection between the first connecting cylinder and the second mounting cylinder, improving the speed of connection and realizing rapid automatic connection of the sizing machine.

Description

Technical Field

[0001] This utility model relates to the field of coupling technology, specifically to a quick-connect automatic coupling structure for sizing machine equipment. Background Technology

[0002] The sizing mill takes steel pipes rolled by the Pilger mill, reheats them in a walking beam furnace, and then sizing them to obtain high-precision dimensions. The sizing roll profile can be adjusted individually or both rolls can be adjusted simultaneously. The sizing roll is the main tool for sizing. It is supported and rotated by bearings in the sizing roll box and ensures the correct position of the sizing roll in the frame. The coupling is a key component in the transmission system of the sizing mill. It is used to connect the drive device (such as motor and reducer) of the sizing mill to the sizing roll shaft, and plays a role in transmitting torque and compensating for relative displacement between shafts.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

An inner tube 7 is fixedly installed at one end of the second mounting cylinder 3. A limiting block 8 is fixedly sleeved on the inner circular wall of the inner tube 7. A first coupling 9 is movably sleeved on the inner circular wall of the limiting block 8. A docking ring 6 is provided on the outer circular wall of the second mounting cylinder 3. Two snap-fit ​​interfaces 23 are opened at one end of the docking ring 6. A pressure groove 24 is opened on the inner bottom surface of the snap-fit ​​interface 23. A pressure plate 25 is rotatably arranged inside the pressure groove 24. A second spring 13 is fixedly installed on the bottom surface of the pressure plate 25. The bottom surface of the second spring 13 is fixedly installed with the inner bottom surface of the pressure groove 24. The outer circular wall of the first connecting cylinder 1 A mounting ring 16 is fixedly fitted, and two connecting blocks 17 are fixedly installed at one end of the mounting ring 16. The two connecting blocks 17 have slots 18 on their adjacent sides. The connecting blocks 17 are movably fitted with the slot interface 23. By setting the mounting ring 16, during docking, the first mounting head 2 and the second mounting head 4 can be fixed to the sizing machine equipment first. During docking, the first connecting cylinder 1 is brought close to the second mounting cylinder 3, so that the connecting blocks 17 on the mounting ring 16 pass into the interior of the slot interface 23. When the connecting blocks 17 pass into the slot interface 23, they will exert pressure on the inside of the slot interface 23. The plate 25 is pressed, which compresses the spring in the pressure groove 24. When the connecting block 17 is fully inserted into the card interface 23, the pressure plate 25 will flip upward by the spring. After flipping, the pressure plate 25 will be locked inside the card groove 18 on the connecting block 17. At this time, the connecting block 17 is fixed inside the card interface 23, thus completing the docking between the first connecting cylinder 1 and the second mounting cylinder 3. In use, the first connecting cylinder 1 can be pushed closer to the second mounting cylinder 3 for docking, which improves the speed of docking and realizes the rapid automatic docking of the sizing machine equipment. Example

[0024] Based on the above embodiment 1, refer to Figure 1 , Figure 2 , Figure 3 and Figure 6The inner tube 7 has a connecting groove 10 at one end. A limiting rod 11 is fixedly installed at one end of the first connector 9. The limiting rod 11 is movably connected to the connecting groove 10. A first spring 12 is fixedly installed at one end of the first connector 9. One end of the first spring 12 is fixedly installed at one end of the inner tube 7. By setting the limiting rod 11, when the first connecting cylinder 1 moves closer to the second mounting cylinder 3 during docking, the second connector 15 inside the first connecting cylinder 1 will squeeze the first connector 9, causing the first connector 9 to move inward due to the compression of the first spring 12. After the first connecting cylinder 1 and the second mounting cylinder 3 are docked, the first connector 9 exerts force against the second connector 15 through the first spring 12, which improves the stability of the connecting block 17 in the locking interface 23. A fixing ring 5 is fixedly sleeved on the outer circular wall of the second mounting cylinder 3. Two third springs 21 are fixedly installed at the ends of the docking ring 6 and the fixing ring 5 that are close to each other. By setting the third springs 21, when disassembly is required, the connecting ring 6 can be moved closer to the fixing ring 5. The movable docking ring 6 can be moved while the pressure plate 25 is pressed by the connecting block 17, thereby separating the docking ring 6 from the mounting ring 16 for quick disassembly. Two connecting rods 20 are fixedly installed at one end of the docking ring 6, and two movable holes 19 are opened at one end of the fixed ring 5. The connecting rods 20 are movably connected to the movable holes 19. By setting the connecting rods 20, when the docking ring 6 is moved, the connecting rods 20 stably compress the third spring 21 between the docking ring 6 and the fixed ring 5, avoiding uneven force on the third spring 21 when it is compressed, which is prone to damage. Two fixing blocks 22 are fixedly installed on the outer circular wall of the docking ring 6. By setting the fixing blocks 22, it is convenient to move the docking ring 6 next to the fixed ring 5. The outer wall of the connecting block 17 fits against the inner wall of the snap-fit ​​interface 23 to prevent the connecting block 17 from shaking inside the snap-fit ​​interface 23. The inner circular walls of the first mounting head 2 and the second mounting head 4 are provided with threads, which facilitates the installation of the first mounting head 2 and the second mounting head 4 at the required docking position.

[0025] Working principle: Please refer to Figures 1-6As shown, by setting the mounting ring 16, when docking, the first mounting head 2 and the second mounting head 4 can be fixed on the sizing machine equipment respectively. When docking, the first connecting cylinder 1 is brought close to the second mounting cylinder 3, so that the connecting block 17 on the mounting ring 16 is inserted into the inside of the clamping interface 23. When the connecting block 17 is inserted into the clamping interface 23, it will squeeze the pressure plate 25 inside the clamping interface 23, and compress the spring in the pressure groove 24. When the connecting block 17 is completely inserted into the inside of the clamping interface 23, the pressure plate 25 will flip upward by the spring. The flipped pressure plate 25 will be stuck inside the clamping groove 18 on the connecting block 17. At this time, the connecting block 17 is fixed inside the clamping interface 23, thus completing the docking between the first connecting cylinder 1 and the second mounting cylinder 3. In use, the first connecting cylinder 1 can be pushed closer to the second mounting cylinder 3 for docking, which improves the speed of docking and realizes the rapid and automatic docking of the sizing machine equipment.
