Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a U-shaped branch pipe processing device with quick-change clamping parts. Background Technology

[0002] In the field of pipeline processing, U-shaped branch pipes are a key pipeline component widely used in various industrial and civil pipeline systems. Due to their unique U-shaped structure, these pipe components can effectively realize the diversion and merging of fluids, meeting complex fluid transportation needs.

[0003] In the processing of U-shaped branch pipes, in order to ensure the accuracy and stability of the processing, it is usually necessary to use a special clamping device to fix and position the pipe to prevent the pipe from moving or deforming during the processing. However, most traditional clamping devices use bolt fixing. Although this method can provide a stable clamping effect, it has many inconveniences in actual operation. When it is necessary to clamp and fix U-shaped branch pipes of different sizes, the operator must loosen or tighten the bolts one by one to disassemble or install the clamping components. This process is not only time-consuming and labor-intensive, but the frequent bolt disassembly and assembly operations will also lead to wear on the bolts and threads. Over time, this wear will gradually increase the maintenance cost of the equipment and increase the possibility of equipment failure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a U-shaped branch pipe processing device with quick-change clamping parts.

[0005] This utility model is achieved using the following technical solution: a U-shaped branch pipe processing device for quick-change clamping parts, comprising a placement base, a right-angle frame fixedly connected to the upper surface of the placement base, a cylinder fixedly connected to the upper surface of the right-angle frame, a piston rod fixedly connected to the output end of the cylinder, a quick-release seat fixedly connected to the bottom end of the piston rod, a connecting rod snapped into the inside of the quick-release seat, an upper clamping plate fixedly connected to the bottom end of the connecting rod, a notch groove opened inside the quick-release seat, an annular groove opened on the inner wall of the quick-release seat, a limit block fixedly connected to the inner wall of the annular groove, movable support blocks fixedly connected to both sides of the outer surface of the connecting rod, an extension frame fixedly connected to the outer surface of the quick-release seat, a telescopic spring fixedly connected to the inner wall of the extension frame, a tension plate abutting the surface of the telescopic spring, a locking rod fixedly connected to the surface of the tension plate, a pull rod fixedly connected to the surface of the tension plate, and positioning slots opened on the surfaces of the quick-release seat and the connecting rod.

[0006] The above technical solution enables the rapid assembly and disassembly of the upper clamping plate, allowing personnel to flexibly replace the appropriate clamping components according to the actual size of the U-shaped branch pipe, which greatly improves processing efficiency. Compared with the traditional method of fixing clamping components with bolts, it is more time-saving and labor-saving when replacing and installing, reduces equipment downtime, improves production efficiency, and reduces labor intensity.

[0007] As a further improvement to the above solution, the movable support block is adapted to the notch groove, and the movable support block is rotatably connected to the inside of the annular groove.

[0008] As a further improvement to the above solution, the locking rod passes through the positioning slots on the surfaces of the quick-release seat and the connecting rod, and the locking rod and the positioning slots are mutually compatible.

[0009] As a further improvement to the above solution, two limiting blocks are provided, and the two limiting blocks are respectively fixedly connected to both sides of the inner wall of the annular groove.

[0010] The above technical solution ensures that the movable support block can accurately reach the predetermined position during rotation, thereby enabling the positioning slot to be precisely aligned.

[0011] As a further improvement to the above solution, guide posts are fixedly connected to the four corners of the upper surface of the placement base, and lower clamps are sleeved on the surface of the guide posts.

[0012] As a further improvement to the above solution, through holes are provided at the four corners of the lower clamp surface, and the through holes are adapted to the guide post.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention unlocks the connecting rod by pulling the pull rod to retract the tension plate, which in turn retracts the locking rod and compresses the telescopic spring. This allows personnel to quickly separate the connecting rod from the quick-release seat, thus facilitating the rapid removal of the upper clamping plate and shortening disassembly time. During installation, the pull rod is pulled again to adjust the angle of the connecting rod, aligning its movable support block with the notch groove before inserting it into the quick-release seat. Rotating the connecting rod allows the movable support block to enter the annular groove. Releasing the pull rod allows the locking rod to pass through the positioning slot under the reset action of the telescopic spring, completing the installation. Personnel can flexibly replace the appropriate clamping components according to the actual size of the U-shaped branch pipe, improving processing efficiency. Compared to the traditional method of fixing clamping components with bolts, this method is more time-saving and labor-saving during replacement and installation. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example:

[0024] Please combine Figure 1-5This embodiment of a U-shaped manifold processing device for quick-change clamping components includes a base 1, a right-angle bracket 2 fixedly connected to the upper surface of the base 1, a cylinder 3 fixedly connected to the upper surface of the right-angle bracket 2, a piston rod 4 fixedly connected to the output end of the cylinder 3, a quick-release seat 5 fixedly connected to the bottom end of the piston rod 4, a connecting rod 6 snapped into the inside of the quick-release seat 5, an upper clamping plate 7 fixedly connected to the bottom end of the connecting rod 6, a notch 8 opened inside the quick-release seat 5, an annular groove 9 opened on the inner wall of the quick-release seat 5, a limit block 10 fixedly connected to the inner wall of the annular groove 9, and movable support blocks 11 fixedly connected to both sides of the outer surface of the connecting rod 6. An extension frame 12 is fixedly connected to the outer surface of the extension frame 12, and a telescopic spring 13 is fixedly connected to the inner wall of the extension frame 12. A tension plate 14 abuts against the surface of the telescopic spring 13, a locking rod 15 is fixedly connected to the surface of the tension plate 14, and a pull rod 16 is fixedly connected to the surface of the tension plate 14. Positioning slots 17 are provided on the surfaces of the quick-release seat 5 and the connecting rod 6. When it is necessary to replace the upper clamping plate 7 to adapt to the processing of U-shaped branch pipes of different sizes, first pull the pull rod 16 to drive the tension plate 14 to retract. When the tension plate 14 retracts, it will drive the locking rod 15 to retract and squeeze the telescopic spring 13. When the locking rod 15 is completely removed from the quick-release seat 5 and the connecting rod 6, the locking rod 15 will retract and squeeze the telescopic spring 13. After the positioning slot 17 on the surface disengages and retracts into the extension frame 12, rotate the connecting rod 6. The movable support block 11 rotates within the annular groove 9, causing it to rotate to the position of the notch groove 8. At this point, pull down the connecting rod 6, and the movable support block 11 separates from the notch groove 8, completing the quick separation and disassembly between the connecting rod 6 and the quick-release seat 5. Then, remove the upper clamping plate 7. When installing the new upper clamping plate 7, pull the pull rod 16 again, causing the locking rod 15 to retract into the extension frame 12. Adjust the angle of the connecting rod 6 so that the movable support block 11 coincides with the notch groove 8. Insert the connecting rod 6 into the quick-release seat 5, and the movable support block 11 passes through the notch groove. After the groove 8 enters the quick-release seat 5 and is installed in place, rotate the connecting rod 6. The movable support block 11 enters the annular groove 9. The inner wall of the annular groove 9 restricts the up-and-down movement of the movable support block 11 and provides support. When the movable support block 11 rotates to the position of the limit block 10, it can no longer rotate. At this time, the positioning slot 17 on the surface of the connecting rod 6 coincides with the positioning slot 17 on the surface of the quick-release seat 5. Release the pull rod 16. Under the reset action of the telescopic spring 13, the pull plate 14 and the locking rod 15 extend. The locking rod 15 passes through the positioning slot 17 on the surface of the quick-release seat 5 and the connecting rod 6, locking the connecting rod 6 inside the quick-release seat 5, thus completing the quick installation of the upper clamping plate 7.

[0025] The movable support block 11 is adapted to the notch groove 8, and the movable support block 11 is rotatably connected to the inside of the annular groove 9.

[0026] The locking rod 15 passes through the positioning slots 17 on the surfaces of the quick-release seat 5 and the connecting rod 6, respectively. The locking rod 15 and the positioning slots 17 are compatible with each other. When it is necessary to fix the connecting rod 6, the locking rod 15 extends under the action of the telescopic spring 13 and is precisely inserted into the positioning slots 17 on the surfaces of the quick-release seat 5 and the connecting rod 6, thus firmly locking the connecting rod 6 inside the quick-release seat 5 to prevent it from loosening or falling off. When it is necessary to remove the connecting rod 6, the pull rod 16 is pulled to retract the locking rod 15 into the extension frame 12, thereby releasing the lock on the connecting rod 6 and allowing it to be smoothly removed from the quick-release seat 5.

[0027] There are two limit blocks 10. The two limit blocks 10 are fixedly connected to the two sides of the inner wall of the annular groove 9. When the movable support block 11 rotates to the position of the limit block 10, the limit block 10 will prevent the movable support block 11 from continuing to rotate, thereby limiting the rotation angle of the connecting rod 6. At this time, the positioning slot 17 on the surface of the connecting rod 6 coincides with the positioning slot 17 on the surface of the quick release seat 5, providing an accurate position for the insertion of the locking rod 15, ensuring that the locking rod 15 can smoothly pass through the two positioning slots 17 and firmly lock the connecting rod 6 inside the quick release seat 5.

[0028] Guide posts 19 are fixedly connected to the four corners of the upper surface of the base 1. The lower clamp 20 is sleeved on the surface of the guide post 19. When the lower clamp 20 needs to be removed, the personnel only need to pull the lower clamp 20 to detach it from the surface of the guide post 19 to complete the quick removal of the lower clamp 20. When installing a new lower clamp 20, the lower clamp 20 is sleeved on the surface of the guide post 19. Through the guiding action of the guide post 19, the lower clamp 20 can be installed quickly and accurately.

[0029] Through holes 18 are provided at the four corners of the surface of the lower clamp 20, and the through holes 18 are adapted to the guide post 19.

[0030] The implementation principle of the U-shaped branch pipe processing device with quick-change clamping parts in this application embodiment is as follows: When it is necessary to replace the upper clamping plate 7 to adapt to the processing of U-shaped branch pipes of different sizes, the disassembly operation is performed first. By pulling the pull rod 16, the pull plate 14 is moved in the retraction direction. The movement of the pull plate 14 causes the locking rod 15 connected to it to be retracted as well. During this process, the telescopic spring 13 is squeezed. When the locking rod 15 is completely disengaged from the positioning slot 17 on the surface of the quick-release seat 5 and the connecting rod 6 and is successfully retracted into the interior of the extension frame 12, the next operation can be performed. At this time, the connecting rod 6 is rotated. With the help of the rotation function of the movable support block 11 inside the annular groove 9, the movable support block 11 is accurately rotated to the position of the notch groove 8. Then, the connecting rod 6 is pulled down so that the movable support block 11 is successfully separated from the notch groove 8, completing the quick separation and disassembly process between the connecting rod 6 and the quick-release seat 5, thereby realizing the disassembly of the upper clamping plate 7.

[0031] When a new upper clamping plate 7 needs to be installed, pull the pull rod 16 again to ensure that the locking rod 15 is retracted into the extension frame 12 so as not to affect the insertion operation of the connecting rod 6. Then, adjust the angle of the connecting rod 6 so that the movable support block 11 on the surface of the connecting rod 6 is precisely aligned with the notch 8 of the quick-release seat 5. Insert the connecting rod 6 into the quick-release seat 5. At this time, the movable support block 11 will also smoothly pass through the notch 8 and enter the quick-release seat 5. After the connecting rod 6 is installed in place, rotate the connecting rod 6 so that the movable support block 11 enters the annular groove 9. The inner wall of the annular groove 9 restricts the up and down movement of the movable support block 11 and also provides... The movable support block 11 provides stable support. When the movable support blocks 11 on both sides of the connecting rod 6 rotate along the inner wall of the annular groove 9 to the position of the limit block 10, the movable support block 11 will be unable to continue rotating. At this time, the positioning slot 17 on the surface of the connecting rod 6 coincides with the positioning slot 17 on the surface of the quick release seat 5. Then, the pulling force on the pull rod 16 is released. Under the reset action of the telescopic spring 13, the pull plate 14 and the locking rod 15 extend smoothly. The locking rod 15 passes through the positioning slot 17 on the surface of the quick release seat 5 and the connecting rod 6, thereby firmly locking the connecting rod 6 inside the quick release seat 5, and finally completing the quick installation of the upper clamping plate 7.

[0032] When it is necessary to remove the lower clamp 20, the operator only needs to pull the lower clamp 20 to make it detach smoothly from the surface of the guide post 19, and the removal of the lower clamp 20 can be completed quickly. When installing a new lower clamp 20, the lower clamp 20 is sleeved on the surface of the guide post 19. With the guidance of the guide post 19, the lower clamp 20 can be installed quickly and accurately.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
