Description

Technical Field

[0001] This invention relates to the field of high-pressure oil pipe end shaping equipment, and more particularly to a high-pressure oil pipe end shaping device. Background Technology

[0002] High-pressure fuel lines are a component of high-pressure fuel systems. They are required to withstand a certain amount of oil pressure and have sufficient fatigue strength to ensure the sealing requirements of the pipeline. Automotive high-pressure fuel lines are mainly found in high-pressure injection diesel engines and high-pressure injection direct injection gasoline engines. They can withstand the oil pressure required during engine operation. In actual use, high-pressure fuel lines require the installation of connecting pipe heads, so pipe end shaping devices are needed to install the connecting pipe heads on the outside of the fuel line opening.

[0003] In the existing technology, during the installation of the connecting pipe head and the pipe opening, the oil pipe has no other supporting force inside. When the oil pipe is squeezed during installation, both the oil pipe and the connecting pipe head may deform. The deformation of the oil pipe will affect the installation of the oil pipe head, and the simultaneous deformation of both will affect the transportation efficiency of the oil pipe in subsequent use and cannot guarantee the sealing of the transport. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-pressure oil pipe orifice shaping device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-pressure oil pipe nozzle shaping device includes a shaping device body and four support legs installed at its bottom. The top of the shaping device body has a through groove, and storage mechanisms are slidably installed at both ends of the through groove. A feeding mechanism is slidably installed on the top of the shaping device body along its length. Fixing mechanisms are slidably installed at both ends of the top of the shaping device body. The fixing mechanisms include a first mounting plate and multiple fixing sleeves. The first mounting plate is slidably installed at one end of the top of the shaping device body, and the multiple fixing sleeves are installed on one side of the outer wall of the first mounting plate along the circumferential direction.

[0007] Preferably, a support rod is installed at one end of the inner side of the fixing sleeve, a nozzle is connected to one side of the outer wall of the support rod, and an air box is connected to the other side of the outer wall of the first mounting plate. The air box is connected to the nozzle through a flexible hose.

[0008] Preferably, a third sliding groove is provided on both sides of the through groove along the length direction, and a plurality of third electric sliders are slidably installed inside the third sliding groove, and a storage mechanism is connected between two corresponding third electric sliders.

[0009] Preferably, the storage mechanism includes a third connecting plate and an L-shaped storage box. The two ends of the outer wall of the third connecting plate are respectively connected to corresponding third electric sliders. The bottom of the storage box is connected to the top of the third connecting plate. A first electric telescopic rod is also connected between the storage box and the third connecting plate.

[0010] Preferably, the top two ends of the shaping device body are provided with first sliding grooves along the length direction. A first electric slider is slidably installed inside the first sliding groove. A first connecting plate is connected between the two first electric sliders at the same end. The first mounting plate is rotatably installed on one side of the outer wall of the first connecting plate by a first electric rotating rod. The bellows is connected to one side of the outer wall of the first connecting plate.

[0011] Preferably, a second electric slider is slidably installed inside the first chute, and a second connecting plate is installed between the two second electric sliders at the same end. The feeding mechanism includes a feeding cylinder and multiple pressure plates. The feeding cylinder is rotatably installed on one side of the outer wall of the second connecting plate via a second electric rotating rod. Multiple grooves are opened on the outer wall of the feeding cylinder along the circumferential direction. Multiple pressure plates are rotatably installed on the outer wall of the feeding cylinder along the circumferential direction.

[0012] Preferably, the plurality of pressure plates are all mounted on the outer wall of the feeding cylinder by rotating in a circumferential direction via a third electric rotary rod, and the pressure plates are located on the top side of the corresponding groove and can seal the groove.

[0013] Preferably, a connector is inserted inside the fixing sleeve, and an installation head is connected to one end of the connector. The installation head can be inserted into the oil pipe opening.

[0014] Preferably, a conveyor belt body is provided on one side of the body of the shaping device. The conveyor belt body can tilt downward to transport high-pressure oil pipes. The discharge end of the conveyor belt body is located on the top side of the upper cylinder. Both sides of the top of the conveyor belt body are connected to protrusions. A push plate that can move in the horizontal direction is connected to one side of the outer wall of the protrusion. A third electric telescopic rod is connected between the push plate and the protrusion.

[0015] Preferably, the inner wall of the fixed sleeve is connected to two arc-shaped electric push rods, and an air hole is opened at one end of the fixed sleeve along the circumferential direction, which is connected to the bellows.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, by setting a fixing mechanism, during the installation of the connector and the oil pipe opening, when the connector is inserted into the high-pressure oil pipe, the support rod can support the inside of the oil pipe to prevent the oil pipe from deforming during the installation process and affecting the installation efficiency. The oil pipe is installed between the connector and the mounting head inside it. During the installation process, the mounting head is inserted into the oil pipe, and the connector is wrapped around the outside of the oil pipe. When the connector is fully inserted into the oil pipe opening, the electric push bar can be controlled to move vertically by extending the second electric telescopic rod. The arc-shaped electric push bar can press the outer wall of the connector to ensure that the connector can be fixed outside the oil pipe opening.

[0018] 2. In this invention, by setting up a feeding mechanism, the oil pipe can be transported to the various grooves of the feeding cylinder through the conveyor belt body. The pressure plate can limit the oil pipe during the downward feeding process of the conveyor belt body, which can ensure that the oil pipe falls accurately into the groove. After the oil pipe falls into the groove, the groove is sealed and closed by the third electric rotating rod pressure plate. The oil pipe is fixed in the groove by the pressure of the pressure plate, which provides working conditions for subsequent shaping of the oil pipe opening. At the same time, the feeding mechanism can also be adaptively adjusted according to the length of the oil pipe, thereby improving the application range of the device.

[0019] 3. In this invention, by setting up nozzles and bellows, the corresponding bellows can be activated. Since one bellows has an air intake function and the other bellows has an air blowing function, after the support rod and connector are inserted into the oil pipe opening, each nozzle can be activated. One nozzle blows air while the other nozzle sucks air to clean the inside of the oil pipe. By blowing air with one nozzle and sucking air with the other nozzle, the flow rate of the gas per unit time is compared with a preset qualified value to detect whether there is a blockage in the oil pipe, thereby improving the overall product quality of the oil pipe.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figure 1-9 A high-pressure oil pipe nozzle shaping device includes a shaping device body 1 and four support legs installed at its bottom. The top of the shaping device body 1 has a through groove, and storage mechanisms are slidably installed at both ends of the through groove. A feeding mechanism is slidably installed on the top of the shaping device body 1 along its length. Fixing mechanisms are slidably installed at both ends of the top of the shaping device body 1. The fixing mechanisms include a first mounting plate 7 and multiple fixing sleeves 18. The first mounting plate 7 is slidably installed on one end of the top of the shaping device body 1, and the multiple fixing sleeves 18 are installed on one side of the outer wall of the first mounting plate 7 along the circumferential direction.

[0032] As a technical optimization of the present invention, a support rod 20 is installed at one end of the inner side of the fixed sleeve 18, and a nozzle 21 is connected to one side of the outer wall of the support rod 20. An air box 13 is also connected to the other side of the outer wall of the first mounting plate 7. The air box 13 is connected to the nozzle 21 through a hose.

[0033] As a technical optimization of the present invention, a third sliding groove 14 is provided on both sides of the through groove along the length direction. Multiple third electric sliders are slidably installed inside the third sliding groove 14, and a storage mechanism is connected between two corresponding third electric sliders.

[0034] As a technical optimization of the present invention, the storage mechanism includes a third connecting plate 16 and an L-shaped storage box 15. The two ends of the outer wall of the third connecting plate 16 are respectively connected to the corresponding third electric sliders. The bottom of the storage box 15 is connected to the top of the third connecting plate 16. A first electric telescopic rod 17 is also connected between the storage box 15 and the third connecting plate 16.

[0035] As a technical optimization of the present invention, the top two ends of the shaping device body 1 are provided with first sliding grooves 5 along the length direction. The first electric slider 26 is slidably installed inside the first sliding groove 5. The two first electric sliders 26 at the same end are connected by a first connecting plate 6. The first mounting plate 7 is rotatably installed on one side of the outer wall of the first connecting plate 6 through the first electric rotating rod 12. The bellows 13 is connected to one side of the outer wall of the first connecting plate 6.

[0036] As a technical optimization of the present invention, a second electric slider 9 is also slidably installed inside the first chute 5. A second connecting plate 10 is installed between the two second electric sliders 9 at the same end. The feeding mechanism includes a feeding cylinder 3 and multiple pressure plates 27. The feeding cylinder 3 is rotatably installed on one side of the outer wall of the second connecting plate 10 by a second electric rotating rod 11. Multiple grooves 4 are opened on the outer wall of the feeding cylinder 3 along the circumferential direction. Multiple pressure plates 27 are rotatably installed on the outer wall of the feeding cylinder 3 along the circumferential direction.

[0037] As a technical optimization of the present invention, multiple pressure plates 27 are all installed on the outer wall of the feeding cylinder 3 by rotating in the circumferential direction via a third electric rotating rod, and the pressure plates 27 are located on the top side of the corresponding groove 4 and can seal the groove 4.

[0038] As a technical optimization of the present invention, a connector 19 is inserted inside the fixing sleeve 18, and an installation head 22 is connected to one end of the connector 19. The installation head 22 can be inserted into the oil pipe opening.

[0039] As a technical optimization of the present invention, a conveyor belt body 2 is provided on one side of the body 1 of the shaping device. The conveyor belt body 2 can tilt downward to transport high pressure oil pipes. The discharge end of the conveyor belt body 2 is located on the top side of the upper feed cylinder 3. Both sides of the top of the conveyor belt body 2 are connected to protrusions 23. A push plate 24 that can move in the horizontal direction is connected to one side of the outer wall of the protrusion 23. A third electric telescopic rod is connected between the push plate 24 and the protrusion 23.

[0040] As a technical optimization of the present invention, the inner wall of the fixed sleeve 18 is connected to two arc-shaped electric push rods 25, and one end of the fixed sleeve 18 is provided with an air hole 28 along the circumferential direction, and the air hole 28 is connected to the bellows 13.

[0041] When using this invention, the shaping device body 1 and the conveyor belt body 2 are placed in a predetermined position and powered on. The connectors 19 to be used are placed inside the storage box 15 and the storage box 15 is installed in a predetermined position. After that, the shaping device body 1 and the conveyor belt body 2 can be used normally.

[0042] When it is necessary to shape the high-pressure oil pipe opening, the oil pipe can be placed horizontally on the top surface of the conveyor belt body 2, and at the same time, the feeding cylinder 3 is rotated by the second electric rotating rod 11. When one of the grooves 4 on the outside of the feeding cylinder 3 is rotated to the bottom of the conveyor belt body 2, the rotation of the feeding cylinder 3 is stopped. The conveyor belt body 2 can then transport the oil pipe into the corresponding groove 4. After that, the feeding cylinder 3 is rotated again to rotate the other idle groove 4 to the bottom of the conveyor belt body 2 and fix it to continue feeding.

[0043] During the feeding process of feeding cylinder 3, as shown in the attached... Figure 1 As shown, there is a certain gap between the conveyor belt body 2 and the feeding cylinder 3, but the pressure plate 27 can limit the oil pipe during the process of the conveyor belt body 2 tilting downward to ensure that the oil pipe falls accurately into the groove 4. After the oil pipe falls into the groove 4, the pressure plate 27 of the third electric rotating rod seals and closes the groove 4. The oil pipe is fixed in the groove 4 by the pressure of the pressure plate 27, which provides working conditions for the subsequent shaping of the oil pipe opening.

[0044] When oil pipes are fixed inside two of the grooves 4 on the outer wall of the feeding cylinder 3, the oil pipe openings can be shaped and processed simultaneously with two oil pipes as a group, while the feeding cylinder 3 can continue to feed materials without interruption.

[0045] During the feeding process of the feeding cylinder 3 into the first set of grooves 4, the storage box 15 can be moved upward by the first electric telescopic rod 17 at the top of the third connecting plate 16. Then, the first connecting plate 6 is slid by the first electric slider 26 inside the sliding groove 5, moving the first connecting plate 6 toward the storage box 15. After the first connecting plate 6 moves, it drives the first mounting plate 7 to move. The connector 19 inside the storage box 15 is then fixed inside the fixing sleeve 18 by an external robotic arm. It should be noted that when the connector 19 is inserted into the oil pipe head by sliding the first mounting plate 7, two of the grooves 4 in the feeding cylinder 3 already have oil pipes fixed inside. The first mounting plate 7 is rotated by the second electric rotating rod 12, aligning the fixing sleeve 18 with the corresponding connector 19 on the outer wall of the first mounting plate 7 with the groove 4 to be processed. The connector 19 is then inserted into the oil pipe opening by sliding the first mounting plate 7 to perform the shaping. It should be noted that the two grooves 4 work together as a group, which can improve work efficiency. At the same time, the other grooves 4 do not contain oil pipes to be shaped. Therefore, when the first mounting plate 7 is inserted into the groove 4 on the outer wall of the feeding cylinder 3, the other solid sleeves 18 are inserted into the empty grooves 4, which will not affect the normal operation of the first mounting plate 7. When the oil pipes in the two grooves 4 of a group have been shaped, the feeding cylinder 3 is rotated 90 degrees, and the pressure plate 27 is rotated to open the groove 4 and send the shaped oil pipes to the storage box connected to the bottom.

[0046] Meanwhile, the two storage boxes 15 can also slide and adjust their positions inside the third slide groove 14. The two storage boxes 15 can abut and limit the two ends of the storage box to ensure that the oil pipe can fall into the storage box after the shaping is completed.

[0047] Furthermore, after the connector 19 inside the fixing sleeve 18 on the outer wall of the first mounting plate 7 is used up, the first mounting plate 7 can be slid adaptably, and the connector 19 inside the storage box 15 can be taken out and fixed inside the fixing sleeve 18 by an external robotic arm. In addition, the fixing sleeves 18 on the outer walls of the first mounting plates 7 on both sides can fix the connector 19 to simultaneously shape both ends of the oil pipe, improving the efficiency of the shaping work.

[0048] When the mounting head 22 in connector 19 is inserted into the high-pressure oil pipe, the support rod 20 supports the inner wall of the mounting head 22, thereby supporting the inside of the oil pipe and preventing deformation of the oil pipe or mounting head 22 during the installation of connector 19 and oil pipe, which would affect the installation efficiency. The oil pipe is installed between connector 19 and its internal mounting head 22. During installation, the mounting head 22 is inserted into the oil pipe, while connector 19 wraps around the outside of the oil pipe. The cross-sectional view of the oil pipe with mounting head 22 inserted into the oil pipe and connector 19 wrapped around the outer wall of the oil pipe is shown in the attached figure. Figure 5 As shown.

[0049] Furthermore, the instruction manual's statement that connector 19 is inserted into the oil pipe opening refers to connector 19's internal mounting head 22 being inserted into the oil pipe, as shown in the attached diagram. Figure 9 As shown, connector 19 and mounting head 22 are a single unit. The term "mounting head 22" is used to more clearly illustrate the internal structure of connector 19.

[0050] When the mounting head 22 in connector 19 is fully inserted into the oil pipe opening, the electric push rod 25 can be controlled to move vertically by extending the second electric telescopic rod. The arc-shaped electric push rod 25 can press against the outer wall of connector 19 to ensure that connector 19 can be fixed outside the oil pipe opening. At the same time, due to the support rod 20 supporting the inside of the oil pipe, the oil pipe will not deform during the process of electric push rod 25 pressing and fixing connector 19.

[0051] When the length of the oil pipe to be shaped is different, and it is necessary to make adaptive adjustments to the body 1 of the shaping device, if the length of the oil pipe is different from that of the oil pipe... Figure 1 The two feeding cylinders 3 shown have the same length after being combined.

[0052] The push plates 24 at both ends of the top of the conveyor belt body 2 can be clamped relative to each other by a third electric telescopic rod, according to the length of the oil pipe. When the movement reaches the same length as the oil pipe, the two push plates 24 stop pushing. The two push plates 24 can limit the oil pipe during the transport of the oil pipe by the conveyor belt body 2. In addition, to ensure that the oil pipe can accurately fall into the groove 4 from the top of the conveyor belt body 2, the spacing of each oil pipe at the top of the conveyor belt body 2 can be adaptively adjusted by a robotic arm to ensure that the oil pipe can accurately fall into the groove 4 during continuous feeding.

[0053] If the length of the oil pipe is greater than the combined length of the two feeding cylinders 3, the two feeding cylinders 3 can be slid towards both ends of the shaping device body 1 according to the length of the oil pipe. Although there is a gap between the feeding cylinders 3, the width of the gap is much smaller than the thickness of the feeding cylinder 3 itself. Therefore, during the feeding process, the oil pipe can still be fixed by the combination of the pressure plate 27 and the groove 4 outside the two feeding cylinders 3. In addition, the position of the push plate 24 can be adjusted synchronously by the third electric telescopic rod so that the push plate 24 can continue to limit the oil pipe.

[0054] If the length of the oil pipe is less than the combined length of the two feeding cylinders 3, the oil pipe opening can be shaped directly by an external robotic arm or manually.

[0055] In addition, as the length of the oil pipe changes, the corresponding storage box will also be adjusted accordingly. Therefore, the sliding storage box 15 inside the third slide groove 14 will be adjusted to adapt to the size of the storage box, ensuring that the two storage boxes 15 can abut and fix the two ends of the storage box, without affecting the shaping work.

[0056] When cleaning the inside of the oil pipe is required during the shaping process, the corresponding bellows 13 can be activated. One bellows 13 has an air suction function, and the other bellows 13 has an air blowing function. The support rods 20 at both ends of the oil pipe, together with the mounting heads 22 in the connectors 19, are inserted into the pipe openings at both ends of the oil pipe. Both ends of the oil pipe are shaped simultaneously. Then, each nozzle 21 is activated. One nozzle 21 blows air while the other nozzle 21 sucks air to clean the inside of the oil pipe. At the same time, due to the presence of the air hole 28, the air hole 28 can clean the outer wall of the oil pipe opening before the connector 19 covers it, preventing impurities on the outer wall of the oil pipe opening from affecting the connection between the connector 19 and the oil pipe opening, and avoiding impurities inside the connection between the connector 19 and the oil pipe opening from affecting the sealing and aesthetics of the connection. It should also be noted that the external of the adsorption-functional air box 13 is also connected to a storage box for collecting residue. The storage box is connected to the adsorption-functional air box 13 through a flexible hose; therefore, the inside of the oil pipe can be cleaned during the installation of the connector 19 and the oil pipe opening.

[0057] During the shaping process, the oil pipe needs to be inspected to prevent impurities from remaining inside the pipe if the nozzle 21 fails to remove them. Air is blown from one nozzle 21 while air is drawn in from the other. The gas flow rate per unit time is compared to a preset acceptable value. If the flow rate matches the preset acceptable value, the oil pipe is not blocked. If the flow rate is less than the preset acceptable value, it indicates a blockage. If a blockage is found, an external robotic arm can remove the defective oil pipe for disposal, preventing further processing of defective pipes and wasting valuable time. Furthermore, detecting blockages improves the overall product quality of the oil pipe. Conversely, if there is a leak between the connector 19 and the oil pipe after installation, some gas will leak from the gap between the oil pipe opening and the connector 19 after the blowing nozzle 21 blows out gas. If the total amount of gas absorbed by the suction nozzle 21 differs from the total amount blown out by the blowing nozzle 21, it indicates a leak at the connector 19. The robotic arm can then remove the leaking oil pipe for disposal.

[0058] The fixed sleeve 18 has multiple outwardly pushing electric push rods 25 connected inside. One side of the electric push rod 25 is connected to the inside of the fixed sleeve 18 via a second electric telescopic rod. After the support rod 20 inside the fixed sleeve 18 is inserted into the connector 19, the electric push rod 25 extends to limit and fix the connector 19. After the connector 19 is installed with the oil pipe opening, the second electric telescopic rod can be retracted to reset the electric push rod 25 and release the connector 19. In addition, when the connector 19 is installed on the outer wall of the oil pipe, the electric push rod 25 is used to continuously press the connector 19 to ensure that the connector 19 will not loosen or leak air between the connector 19 and the oil pipe opening during actual use.
