Description

Technical Field

[0001] This invention relates to the field of flange production line technology, and more specifically, to a continuous production mechanism for pipe flanges. Background Technology

[0002] The continuous production of pipe flanges requires sequential external wall machining, internal wall machining, chamfering, and stacking. In actual production, gantry robots are usually used to transfer flanges between different processes. For example, unprocessed flanges are first fed sequentially by a conveyor belt or conveyor rollers. The gantry robot takes out the first flange that has been machined in the first lathe and at the same time takes out an unprocessed second flange and loads it into the first lathe. Then, the first flange is placed on the flipping station. After the first flange is flipped, it is clamped by the gantry robot and loaded into the second lathe. Flipping is to facilitate the machining of the internal wall. After the first flange is machined, the gantry robot takes the first flange out of the second lathe and places it on the chamfering fixture for chamfering. After the chamfering is completed, the gantry robot transfers the first flange to the stacking fixture for stacking.

[0003] When using the aforementioned continuous production mechanism for flange processing, it was found that the existing tooling is not suitable for flanges of various sizes during chamfering. After processing one type of flange, changing to another type or size requires replacing the chamfering tooling or disassembling and repositioning it, which is too cumbersome and delays production. Therefore, improvements to the existing production mechanism are needed to solve this problem. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of the present invention provide a continuous production mechanism for pipe flanges, which solves the technical problem that the flange chamfering tooling in the prior art cannot be adapted to flanges of various sizes.

[0005] According to one aspect, at least one embodiment of the present invention provides a continuous production mechanism for pipe flanges, comprising a lathe first, a flipping fixture, a lathe second, a chamfering fixture, a stacking fixture, and a gantry robot for transferring pipe flanges arranged sequentially. The chamfering fixture includes a worktable and a tool assembly and a moving assembly spaced apart on the worktable. The tool assembly includes a mounting frame first, a tool first, and a tool second. Both the tool first and the tool second are rotatably mounted on the mounting frame first. The tool first is raised and lowered above the tool second. The tool first and the tool second are respectively used to chamfer the upper and lower end faces of the pipe flange. The moving assembly has a clamping member for holding the pipe flange. The clamping member can drive the pipe flange to move horizontally to approach or move away from the tool second.

[0006] As a further technical solution, the mounting bracket is provided with a linear drive, the output end of which is connected to a rotary drive, and the output end of which is connected to the first cutting tool. The linear drive is used to adjust the distance between the first cutting tool and the second cutting tool. The moving component includes a guide rail on the worktable, a slide table that moves on the guide rail, and a clamping member on the slide table. The clamping member can clamp and fix the pipe flange, and adjust the distance between the pipe flange and the first cutting tool through the slide table.

[0007] As a further technical solution, the flipping fixture includes a frame and a flipping frame rotatably mounted on the frame. Two clamping plates are movably mounted on the flipping frame and can move towards each other or away from each other. The flipping frame is configured to clamp and drive the pipe flange to flip by the two clamping plates. A support plate is also raised and lowered on the frame, and the support plate is used to support the pipe flange before and after flipping.

[0008] As a further technical solution, the palletizing fixture includes a frame two and two rotating rings rotatably mounted on the frame two. The two rotating rings are spaced apart, and a connecting frame is provided between the two rotating rings. The connecting frame is provided with a radially sliding conveyor component one, and a conveyor component two is fixedly mounted opposite to the conveyor component one. The connecting frame is also slidably mounted with two radially movable clamping plates two, which are located between the conveyor component one and the conveyor component two. The conveyor component one is configured to move downward and cooperate with the conveyor component two to lock the vertical position of the pipe flange, and can follow the rotating ring to rotate below the conveyor component two to transport the pipe flange. The two clamping plates two are configured to move towards each other and lock the horizontal position of the pipe flange. The rotating ring is configured to clamp the pipe flange through the conveyor component one, the conveyor component two, and the two clamping plates two to drive the pipe flange to rotate, and to transport the upright and reversed pipe flanges forward alternately.

[0009] As a further technical solution, the palletizing fixture also includes a frame three and a conveyor three that is lifted and mounted on the frame three. The conveyor three is located on one side of the frame two, and a palletizing box is provided on the output end side of the conveyor three. The conveyor three is configured to receive and stack the pipe flanges conveyed from the conveyor one or the conveyor two after being lifted and mounted, and to convey the pipe flanges into the palletizing box.

[0010] As a further technical solution, a widening diversion plate is provided at one end of the palletizing box adjacent to the conveyor three. The widening diversion plate is connected to the palletizing box. A partition is provided on the palletizing box, which divides the palletizing box into a palletizing area one and a palletizing area two spaced apart along the width direction of the conveyor three. A guide plate that reciprocates along its width direction is provided below the widening diversion plate. The two ends of the guide plate have a guide limiting part one and a guide limiting part two extending above the widening diversion plate, respectively. The guide limiting part one is configured to move with the guide plate and then press against the partition and the output end of the conveyor three, respectively, to close the palletizing area one and allow the pipe flange to enter the palletizing area two. The guide limiting part two is configured to move with the guide plate and then press against the partition and the output end of the conveyor three, respectively, to close the palletizing area two and allow the pipe flange to enter the palletizing area one.

[0011] As a further technical solution, the guide plate also has a push block one and a push block two at its two ends. The push block one is located on the side of the guide plate near the palletizing box and is used to push the pipe flange into the palletizing area one after moving with the guide plate. The push block two is located on the side of the guide plate near the palletizing box and is used to push the pipe flange into the palletizing area two after moving with the guide plate.

[0012] As a further technical solution, a baffle is provided on each side of the palletizing box.

[0013] As a further technical solution, both push block one and push block two are inclined. Push block one gradually approaches the stacking area two along the conveying direction of the pipe flange, and push block two gradually approaches the stacking area one along the conveying direction of the pipe flange.

[0014] As a further technical solution, the clamping component is a three-jaw chuck; the first conveyor, the second conveyor, and the third conveyor are conveyor belts, conveyor chains, or conveyor rollers.

[0015] The beneficial effects of this invention are as follows:

[0016] In this invention, the horizontal distance between the pipe flange and the first tool is adjusted by the cooperation of the slide table and the guide rail, and the vertical distance between the first tool and the second tool is adjusted by the linear drive component. The two are combined to form a bidirectional adjustment structure, which can adapt to pipe flanges of different sizes without replacing or disassembling the chamfering fixture components, thus solving the problem of poor adaptability of existing chamfering fixtures.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] This invention relates to the field of flange production line technology, specifically a continuous production mechanism for pipe flanges, applicable to automated continuous production scenarios of various pipe flanges in the petroleum, chemical, and municipal engineering fields. Pipe flanges are core components in fluid transport systems, enabling pipe connections. Their production process requires sequential completion of external wall machining, internal wall machining, chamfering, and stacking. To improve production efficiency, the industry commonly uses gantry robots in conjunction with multi-station tooling to automate transfer between processes. However, existing chamfering tooling in production mechanisms cannot adapt to flanges of multiple sizes; changing flange models requires disassembling or replacing the tooling, which is cumbersome and affects production efficiency. This embodiment solves the above-mentioned technical problems through optimized design of each tooling structure, while simultaneously improving the automation level and operational stability of the overall production process.

[0032] like Figure 1 The diagram shows a three-dimensional schematic of a continuous production mechanism according to an embodiment of the present invention. The continuous production mechanism includes a gantry robot 1 and a lathe 2, a flipping fixture 3, a second lathe 4, a chamfering fixture 5, and a stacking fixture 6 arranged sequentially. The gantry robot 1, as the core component for transfer between processes, is responsible for gripping and transferring pipe flanges between the lathe 2, the flipping fixture 3, the second lathe 4, the chamfering fixture 5, and the stacking fixture 6. The lathe 2 is used for machining the outer wall of the pipe flange. The flipping fixture 3 is used to achieve a 180-degree flip of the pipe flange to meet the orientation requirements of the second lathe 4 for machining the inner wall of the pipe flange. The chamfering fixture 5 is used to chamfer the machined pipe flange. The stacking fixture 6 completes the orderly stacking and storage of the chamfered pipe flanges. The cooperation of these components forms a complete continuous production process for pipe flanges.

[0033] like Figure 2The diagram shows a schematic representation of a chamfering fixture according to an embodiment of the present invention. The chamfering fixture 5 includes a worktable 51 and a tool assembly 52 and a moving assembly 53 spaced apart on the worktable 51. The tool assembly 52 includes a mounting bracket 521 fixedly mounted on the worktable 51. A linear drive 522 is mounted on the mounting bracket 521, and the output end of the linear drive 522 is connected to a rotary drive 523. The output end of the rotary drive 523 is connected to a tool 524. A second tool 525 is also rotatably mounted on the mounting bracket 521, located below the tool 524. The moving assembly 53 includes a guide rail 531 fixed on the worktable 51. A slide 532 is movably mounted on the guide rail 531, and a clamping member 533 is mounted on the slide 532 for clamping and fixing pipe flanges. Optionally, the clamping component 533 adopts a three-jaw chuck structure. The chuck body of the three-jaw chuck is fixedly connected to the slide table 532. The three jaws are evenly distributed along the circumference of the chuck body and can synchronously move closer to each other or further away from each other along the radial direction of the chuck body. Optionally, the linear drive component 522 can be an electric pusher, a cylinder, a hydraulic cylinder, a lead screw, or other existing drive structure. The linear drive component 522 can be a drive component that can realize linear reciprocating motion, such as an electric push rod, a cylinder, or a hydraulic cylinder. The rotary drive component 523 can be a drive component that can provide rotational power, such as a servo motor or a stepper motor.

[0034] The gantry robot 1 transfers the pipe flange machined by lathe 2 4 to the clamping part 533 of the moving assembly 53. The jaws of the three-jaw chuck move synchronously towards each other to center and clamp the pipe flange. Then, the slide 532 moves along the guide rail 531, adjusting the horizontal distance between the pipe flange and tool 1 524, aligning the chamfered part of the pipe flange with the machining area between tool 1 524 and tool 2 525. The linear drive 522 actuates, driving the rotary drive 523 and tool 1 524 to move vertically, adjusting the vertical distance between tool 1 524 and tool 2 525 to fit the thickness of the chamfered part of the pipe flange. After adjustment, the rotary drive 523 rotates tool 1 524, bringing the chamfered part of the pipe flange into contact with tool 2 525 and driving tool 2 525 to rotate synchronously, thus completing the chamfering process. After processing, the grippers of clamping part 533 are turned away from the loosened pipe flange, and the gantry robot 1 transfers it to the stacking fixture 6.

[0035] The chamfering fixture provided in this embodiment achieves the adjustment of the horizontal distance between the pipe flange and the first tool 524 through the cooperation of the slide table 532 and the guide rail 531, and the adjustment of the vertical distance between the first tool 524 and the second tool 525 through the linear drive component 522. The two together form a bidirectional adjustment structure, which can adapt to pipe flanges of different sizes without replacing or disassembling the components of the chamfering fixture 5, thus solving the problem of poor adaptability of existing chamfering fixtures. As an intermediate process component of the continuous production mechanism, the chamfering fixture 5 is designed to be compatible with the transfer rhythm of the gantry robot 1, the second lathe 4, and the stacking fixture 6. The quick clamping and releasing of the clamping component 533 can be coordinated with the transfer action of the gantry robot 1. The adjustment process of the slide table 532 and the linear drive component 522 can be completed quickly after the gantry robot 1 completes the transfer, without additional waiting time, so that the chamfering process is smoothly connected with the preceding and following processes, ensuring the continuity and stability of the entire pipe flange continuous production mechanism.

[0036] like Figure 3 The diagram shows a schematic representation of a flipping fixture according to an embodiment of the present invention. The flipping fixture 3 includes a frame 31 and a flipping frame 32 rotatably mounted on the frame 31. Two clamping plates 33 are movably mounted on the flipping frame 32, and the two clamping plates 33 can move towards each other or away from each other along the flipping frame 32. A support plate 34 is also vertically mounted on the frame 31. The rotation of the flipping frame 32 can be achieved by a motor in conjunction with a gear transmission mechanism. The movement of the clamping plates 33 can be driven by a cylinder or a lead screw and nut mechanism. The lifting and lowering of the support plate 34 can be achieved by an electric push rod or a hydraulic cylinder.

[0037] The gantry robot 1 moves the pipe flange processed by lathe 2 to the top of the flipping fixture 3. At this time, the pallet 34 is in an upward state, and the gantry robot 1 places the pipe flange on the pallet 34. The height of the pallet 34 is slightly adjusted so that the pipe flange is between the two clamping plates 33. The two clamping plates 33 move towards each other to clamp and fix the pipe flange. The pallet 34 descends and disengages from the pipe flange, and the flipping frame 32 drives the clamping plates 33 and the pipe flange to rotate 180 degrees to complete the flipping. After the flipping is completed, the pallet 34 rises again to support the pipe flange, and the clamping plates 33 move away from the pipe flange to release it. The gantry robot 1 then moves the flipped pipe flange to lathe 4.

[0038] The chamfering fixture provided in this embodiment, through the movable design of the two clamping plates 33, can adapt to pipe flanges of different sizes. It can complete the flipping operation without changing the clamping components, and works synergistically with the adapting structure of the chamfering fixture 5, improving the multi-specification adaptability of the entire production mechanism. The pallet 34 receives the pipe flange before flipping and supports it after flipping, ensuring that the pipe flange remains stably supported during the connection phase of transfer and flipping, preventing the pipe flange from shaking or falling off during the flipping process, and improving the safety and stability of the flipping process. The rotation of the flipping frame 32 is smoothly connected with the movements of the clamping plates 33 and the pallet 34, enabling rapid completion of the flipping process and ensuring the efficiency of the process connection from lathe 2 to lathe 4.

[0039] like Figures 4-6 The diagram shows a schematic representation of a palletizing fixture according to an embodiment of the present invention. The palletizing fixture 6 includes a frame 61 and two rotating rings 62 rotatably mounted on the frame 61. The two rotating rings 62 are spaced apart in a horizontal direction, and a connecting frame 63 is fixedly connected between them. A first conveyor 64 is vertically mounted on the connecting frame 63, and a second conveyor 65 is mounted below the first conveyor 64. Two clamping plates 66 are movably mounted between the first conveyor 64 and the second conveyor 65, and the two clamping plates 66 can move towards each other or away from each other. Optionally, the first conveyor 64 can be a conveyor roller structure, and the second conveyor 65 can be a conveyor belt structure. The movement of the clamping plates 66 can be driven by a screw and nut mechanism, and the rotation of the rotating rings 62 can be achieved by a motor in conjunction with a chain drive mechanism.

[0040] To improve the space utilization of palletizing, such as Figure 6 As shown, pipe flanges are stacked using a staggered arrangement, hence the aforementioned structure is used to flip the incoming pipe flanges to achieve the subsequent staggered arrangement. The specific workflow is as follows: The gantry robot 1 moves the chamfered pipe flange onto conveyor 64. Conveyor 64 then starts conveying the pipe flange to the designated position. If the pipe flange needs to be conveyed face-forward, conveyor 64 remains stationary, while the two clamping plates 66 move towards each other but do not press against the pipe flange, limiting its horizontal position. Conveyor 65 then starts conveying forward. If the pipe flange needs to be conveyed face-forward, conveyor 64 descends, cooperating with conveyor 65 to clamp the vertical position of the pipe flange. Clamping plates 66 clamp the pipe flange, and the flipping ring 62 drives the connecting frame 63 and the entire clamping and conveying structure to rotate 180 degrees to complete the flipping of the pipe flange. Subsequently, clamping plates 66 release, and conveyor 64 and conveyor 65 simultaneously convey the pipe flange. By alternately controlling the rotation state of the flipping ring 62, the staggered forward conveying of pipe flanges placed face-forward is achieved.

[0041] The palletizing fixture provided in this embodiment uses a flipping ring 62 to rotate the flanges. Combined with the locking structure of conveyor component 64, conveyor component 65, and clamping plate 66, it achieves accurate control of the alternating forward and reverse stacking of flanges. This ensures that the flanges are output in an alternating manner, providing a preliminary guarantee for reducing gaps and improving stacking stability in subsequent stacking, and solving the problem of loose stacking caused by chaotic flange orientation in traditional palletizing. Conveyor component 64 has both conveying and lifting / locking functions, conveyor component 65 provides vertical positioning, and clamping plate 66 provides horizontal positioning. All three components are integrated with the flipping ring 62 into the same structure, eliminating the need for separate flipping and conveying devices, simplifying the overall structure of the palletizing fixture 6, and reducing the space occupied by the equipment.

[0042] The palletizing fixture 6 also includes a frame 3 67, which is equipped with a lifting drive structure. Its output end is connected to a conveyor 3 68, for example, using a hydraulic cylinder in conjunction with a guide rail to achieve lifting. The conveyor 3 68 is located on the output side of the frame 2 61. A palletizing box 69 is placed on one side of the output end of the conveyor 3 68, with the opening of the palletizing box 69 facing the output direction of the conveyor 3 68. For flanges that are transported in an alternating manner, orderly palletizing is achieved through receiving and stacking. The lifting and lowering of the conveyor 3 68 can be adjusted according to the stacking height of the flanges in the palletizing box 69 to avoid damage caused by excessive flange drop. The conveying function of the conveyor 3 68 transfers the received flanges to the palletizing box 69, forming a complete "receiving-conveying-palletizing" process. The workflow is as follows: Conveyor 1 64 and Conveyor 2 65 transport the alternating pipe flanges to Conveyor 3 68. At this time, the height of Conveyor 3 68 is adjusted to be flush with the output end of Frame 2 61 according to the initial state inside the palletizing box 69. When Conveyor 3 68 receives a flange, if there is no flange in the palletizing box 69, Conveyor 3 68 will directly start to transport the flange to the bottom of the palletizing box 69. If there are already flanges stacked in the palletizing box 69, Conveyor 3 68 will first adjust to the height of the top flange through the lifting drive structure, and then start the conveyor to stack the flanges on top. The above process is repeated until the flanges in the palletizing box 69 are stacked to the specified height. After that, a new palletizing box 69 is replaced and the stacking continues.

[0043] The palletizing fixture provided in this embodiment improves palletizing efficiency and stacking regularity through the lifting function of the three-way conveyor 68. The three-way conveyor 68 is located between the frame 61 and the palletizing box 69, forming a bridge between processes. It directly transfers the flange from the staggered conveying stage to the palletizing stage without the need for additional intervention from the gantry robot 1, reducing the frequency of transfer equipment movements and lowering energy consumption. Simultaneously, it creates a closed loop within the internal process of the palletizing fixture 6, enhancing automation. It adapts to different stacking height requirements: the lifting range of the three-way conveyor 68 can be adjusted according to the height of the palletizing box 69. Whether it is a small or large palletizing box, complete stacking can be achieved through height adjustment without replacing the palletizing support components, improving the adaptability and flexibility of the palletizing fixture 6.

[0044] An expansion and diversion plate 681 is fixedly installed at the output end of the conveyor component 68. The expansion and diversion plate 681 is connected to the palletizing box 69. A partition 691 is fixedly installed inside the palletizing box 69, dividing the palletizing box 69 into a first palletizing area 692 and a second palletizing area 693. A guide plate 682 that reciprocates perpendicular to the conveying direction is provided on the outer side of the expansion and diversion plate 681. A guide limiting part 683 and a guide limiting part 684 are respectively provided at both ends of the guide plate 682. A push block 685 and a push block 686 are also provided at both ends of the guide plate 682. The push block 685 is located on one side of the guide limiting part 683, and the push block 686 is located on one side of the guide limiting part 684. Furthermore, both push block 685 and push block 686 are inclined. Push block 685 gradually approaches the second stacking area 693 along the conveying direction of the pipe flange, while push block 686 gradually approaches the first stacking area 692 along the conveying direction of the pipe flange. A baffle 694 is also provided on each side of the stacking box 69. The reciprocating movement of the guide plate 682 can be driven by a cylinder or a crank-connecting rod mechanism.

[0045] Conveyor 1 64 and Conveyor 2 65 transport the alternating pipe flanges to Conveyor 3 68. Conveyor 3 68 adjusts its lifting height according to the stacking height in the palletizing box 69, so that the receiving surface is flush with the output end of the rack 2 61 or with the uppermost pipe flange in the palletizing box 69. Conveyor 3 68 starts and transports the pipe flange to the widening diversion plate 681. When it is necessary to guide the pipe flange into the second palletizing area 693, the guide plate 682 moves, so that the guide limiting part 1 683 presses against the partition plate 691 and the output end of the conveyor 3 68, sealing the entrance of the first palletizing area 692. The pipe flange is blocked by the guide limiting part 1 683 and enters the second palletizing area 693. At the same time, the pusher block 1 685 moves with the guide plate 682, pushing the pipe flange stuck at the entrance of the first palletizing area 692 into the first palletizing area 692. When a pipe flange needs to be introduced into the first stacking area 692, the guide plate 682 moves in the opposite direction, causing the guide limiting part 684 to close the entrance of the second stacking area 693. The pipe flange enters the first stacking area 692, and the pusher block 686 pushes the pipe flange at the entrance of the second stacking area 693 inward. The inclined pusher blocks 685 and 686 apply a component force inward to the pipe flange during pushing, guiding the pipe flange to be evenly distributed within the stacking area. The baffles 694 on both sides of the stacking box 69 prevent the pipe flange from shifting to the sides, avoiding it from falling out of the stacking box 69.

[0046] The lifting function of the conveyor 68 precisely matches the stacking height, preventing pipe flanges from shifting or being damaged due to excessive falling distance, thus improving the neatness of the stacking. Simultaneously, its conveying function enables automated transfer of pipe flanges without manual intervention, improving stacking efficiency. The widened diversion plate 681 expands the receiving range at the end of the conveying process. The guide limiting parts 683 and 684 achieve zone control through pressure sealing, allowing pipe flanges to accurately enter the preset stacking area, facilitating the classification and management of pipe flanges of different batches or specifications. Push blocks 685 and 686 move with the guide plate 682, pushing pipe flanges stuck at the entrance of the stacking area into the interior, preventing conveying blockages. The baffles 694 on both sides of the stacking box 69 form vertical barriers, preventing pipe flanges from falling, improving the safety of the stacking process. Furthermore, their simple structure and strong adaptability allow for size adjustment according to the specifications of the stacking box 69.

[0047] Conveyor Component 1 (64), Conveyor Component 2 (65), and Conveyor Component 3 (68) can be selected from conveyor belts, conveyor chains, or conveyor roller structures according to actual production needs. Different conveyor structures can be adapted to different working scenarios.
