Description

Technical Field

[0001] This invention relates to the field of flange assembly welding technology, and more specifically, to a multifunctional integrated displacement welding workstation. Background Technology

[0002] In welding applications involving flange and pipe fitting assembly, workpieces typically require multi-angle, multi-position welding and repair welding operations. Traditionally, operators frequently lift workpieces to flip them and adjust their angles, which is not only inefficient but also poses safety hazards such as workpiece slippage and loss of control of lifting equipment. Especially when the workpiece structure is complex (e.g., pipe fittings and flanges require welding on both the inner and outer sides), the increased manual intervention further exacerbates the operational risks and difficulties.

[0003] For flange assembly precision control, current methods generally rely on manual visual inspection, manual adjustment, and conventional measuring tools (such as tape measures) for positioning. This approach is insufficient to meet high-precision assembly requirements: for example, the center distance tolerance between two flanges must be ≤ ±0.1mm, and the perpendicularity between the fitting and the flange must be ≤ 3‰. However, manual operation easily leads to deviations in flatness (requirement ≤ ±0.5mm) and parallelism (requirement ≤ 0.1mm). When the workpiece undergoes unpredictable inward / outward deformation due to previous welding, existing technologies lack reliable correction methods and cannot ensure that the fitting is accurately embedded in the flange hole.

[0004] Furthermore, the existing production model lacks standardized processes and integrated equipment. Workpiece clamping, flange positioning, and welding are performed in a fragmented manner, leading to chaotic process sequences, fluctuating welding quality, and low production capacity. This non-cooperative operating method is ill-suited to the flexible manufacturing needs of multi-specification workpieces (such as flange center distances ranging from 200–4000 mm), hindering the optimization of product quality and production efficiency.

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0045] Depend on Figures 1 to 10As shown, this embodiment of the invention provides a multifunctional integrated displacement welding workstation, comprising a first fixed base 1, a first slide 5 and a second slide 11 engaged with the first fixed base 1, a first support member 6 engaged with the first slide 5, a second support member 10 engaged with the second slide 11, a first drive member 12 adapted to drive the first slide 5 and the second slide 11 to move closer and further apart, two displacement components 2 respectively engaged with the two slides, and two clamping components 4 respectively engaged with the two displacement components 2. The first support member 6 and the second support member 10 are adapted to position and fix flanges. The displacement components 2 are adapted to move up and down and rotate the clamping components 4.

[0046] The clamping assembly 4 includes a clamping base 32 engaged with the displacement assembly 2, a first clamping member 24 engaged with the clamping base 32, and two floating clamping members 27. The clamping members are adapted to abut against the pipe fitting. The floating clamping members 27 extend and retract by pressure.

[0047] The multifunctional integrated displacement welding workstation also includes a second drive member respectively engaged with the two floating clamping members 27. The second drive member is adapted to drive the floating clamping members 27 to abut against the pipes on both sides of the workpiece by at least two pressure levels, so that the workpiece can move relative to the two displacement components 2 when clamping the workpiece.

[0048] Specifically, the two pressure settings are high pressure and low pressure. When both floating clamping members 27 are driven simultaneously using high pressure or low pressure, the workpiece position remains unchanged, but the workpiece and / or the pipes on both sides deform toward the center. When one floating clamping member 27 uses high pressure and the other floating clamping member 27 uses low pressure, the workpiece moves toward the side with low pressure. This multi-functional integrated displacement welding workstation is suitable for performing a flange assembly displacement method. The flange assembly displacement method is as follows: S1. Determine whether the pipe fittings on both sides of the workpiece are shaped inward or outward.

[0049] Specifically, the workpiece has pipe fittings on both sides. Due to workpiece deformation during production, the pipe fittings on both sides may exhibit either an outward-pointing (narrower at the top and wider at the bottom) or an inward-pointing (wider at the top and narrower at the bottom) structure. When either an inward or outward-pointing structure occurs, the distance between the bottom of the pipe fittings differs from the distance of the pre-set flange holes, making it impossible to insert the flange. Therefore, a flange assembly displacement method according to this invention is required.

[0050] Whether a workpiece is oriented inwards or outwards can be determined manually or automatically using computer vision; this invention does not impose any specific limitations on this.

[0051] S2. When the pipe is in an inward-pointing position, the first floating clamping member 27 is driven by high pressure from the reset position, and the second floating clamping member 27 is driven by low pressure until the pipe fitting on one side is inserted into the flange. Then, the two slides are driven closer together, the first floating clamping member 27 is driven by low pressure, and the second floating mechanism is driven by high pressure until the pipe fitting on the other side is inserted into the flange.

[0052] When the two pipe fittings on both sides of the workpiece are octagonal, the distance between the bottoms of the two pipe fittings is less than the distance between the two flanges, and the position is between the two flanges. Preferably, step S2 includes steps S21 to S22.

[0053] S21. When it is determined that the pipe fittings on both sides of the workpiece are in an inward-pointing shape and the two flanges are in the reset position, the first floating clamping member 27 is extended by high pressure and the second floating clamping member 27 is extended by low pressure, so that the workpiece moves toward the second floating clamping member 27 until the mounting holes 20 of the pipe fitting and flange on one side are aligned and inserted.

[0054] S22, drive the first slide 5 and the second slide 11 to move closer to each other, while driving the first floating clamping member 27 to extend with low pressure and driving the second floating mechanism to extend with high pressure until the mounting holes 20 of the pipe fitting and the other flange on the other side are aligned and inserted, thereby completing the assembly of the flange and pipe fitting.

[0055] S3. When the pipe is in an outward-pointing position, drive the two slides away from the reset position and drive the two floating clamping members 27 to extend until the pipe on one side is inserted into the flange. Then, continue to drive the two slides away from the reset position and drive the two floating clamping members 27 to extend until the pipe on the other side is inserted into the flange.

[0056] When the two pipe fittings on both sides of the workpiece are octagonal, the distance between the bottoms of the two pipe fittings is greater than the distance between the two flanges, and the two flanges are located between the bottoms of the two pipe fittings. Preferably, step S3 includes steps S31 to S32.

[0057] S31. When it is determined that the pipe fittings on both sides of the workpiece are outwardly oriented, the first slide 5 and the second slide 11 are driven away from each other to increase the distance between the two flanges. At the same time, the high pressure drives the two floating clamping members 27 to extend, maintain the position of the workpiece and drive the pipe fittings on both sides to move closer to each other until the pipe fitting on one side aligns with the flange hole on one side and is inserted.

[0058] S32. Continue to drive the first slide 5 and the second slide 11 away from each other, further increasing the distance between the two flanges. At the same time, continue to drive the two floating clamping members 27 out under high pressure, further maintaining the position of the workpiece and driving the pipes on both sides closer to each other until the pipe on the other side aligns with the flange hole on the other side and is inserted.

[0059] By assembling the pipe fittings and flanges on both sides of the inner octagonal structure in step S2, and assembling the pipe fittings and flanges on both sides of the outer octagonal structure in step S3, the assembly of pipe fittings and flanges can be completed well, greatly simplifying the assembly steps and improving the assembly efficiency.

[0060] S4. The reset slide and floating clamping member 27 move the flange to the preset position. Specifically, the first slide 5 and the second slide 11 are reset, moving the two flanges to the predetermined specification position. At the same time, the two floating clamping members 27 are retracted, and only the first clamping member 24 clamps the workpiece. This ensures that the dimensions, flatness, and parallelism between the two flanges meet the requirements.

[0061] In this embodiment, the reset position of the first slide 5 and the second slide 11 is such that the two flanges are in positions that meet the specifications. The reset position of the floating clamping member 27 is the retracted state. After aligning the pipe fittings on both sides and inserting them into the flanges to complete the assembly, resetting the two floating clamping members 27 can release the external force applied to the workpiece; resetting the first slide 5 and the second slide 11 can drive the first support structure and the second support member 10 to move the two flanges to the preset position, so that the distance, parallelism, and flatness between the two flanges meet the requirements.

[0062] S5. Fix the flange to the pipe fitting by welding.

[0063] S6. Annealing is used to eliminate internal stress in workpieces and fittings, thus setting their shape. Specifically, annealing eliminates internal stress in workpieces and fittings, enabling them to be shaped and maintain their current position to meet dimensional, flatness, and parallelism requirements.

[0064] Preferably, step S0 is included before step S1. S0: Welding the reinforcing rib onto the workpiece. In this embodiment, the reinforcing rib is installed before the flange. In other embodiments, the reinforcing rib can be installed after the flange, as long as it is installed before the retraction process. This invention does not specifically limit this.

[0065] Based on the above embodiments, in an optional embodiment of the present invention, such as Figures 7 to 10As shown, the clamping assembly 4 further includes a lug limiting member 31. The lug limiting member 31 includes a lug base 34 engaged with the clamping base 32 and provided with a lug groove 40, and a first limiting pin 35 movably engaged with the lug base 34. The lug groove 40 is adapted to accommodate a lug provided with a lifting hole. The first limiting pin is adapted to insert into the lifting hole located in the lug groove 40 to prevent the lug from disengaging from the lug groove 40. In this embodiment, the lug base 34 is provided with a first pin hole 39 and a C-shaped hole 38 communicating with the first pin hole 39. The first limiting pin 35 is provided with a first pin portion 36 located in the first pin hole 39, and a first handle portion 37 extending outward from the first pin portion 36 through the C-shaped hole 38. Preferably, the lug limiting member 31 further includes a first elastic member (not shown) located between the lug base 34 and the first limiting pin 35. The first elastic element is adapted to drive the first handle portion 37 to be fitted into the end of the C-shaped hole 38 near the side of the lug groove 40.

[0066] Specifically, since the first pin hole 39 is located between the pipe fitting and the clamping base 32, the design of the extended handle makes it easier to adjust the first limiting pin 35, thereby fixing the lifting lug on the pipe fitting to the lifting lug limiting member. In other embodiments, the first limiting pin 35 can be directly set as a spring pin structure. This invention does not specifically limit this, as long as it can limit the lifting lug to the lifting lug groove 40.

[0067] The lifting lug limiting component 31 also includes a lifting lug pad 33. The lifting lug pad 33 has a U-shaped structure, and a spring pin (not shown) is disposed facing inwards from the U-shape. The lifting lug pad 33 is adapted to be embedded in the lifting lug groove 40 and fitted onto the first limiting pin 35. Specifically, workpieces of different specifications have lifting lugs of different sizes and thicknesses, and the lifting lug pad 33 can securely fix the lifting lugs in the lifting lug groove 40, preventing wobbling between the workpiece, pipe fitting, and clamping assembly 4.

[0068] Preferably, there are two first clamping members 24. Two floating clamping members 27 are located between the two first clamping members 24. The lifting lug limiting assembly is located between the two floating clamping members 27. In this embodiment, the two clamping assemblies 4 have identical structures. In other embodiments, adjustments can be made according to the actual structure of the product, and the two clamping assemblies 4 may have different structures. For example, the number of first clamping members 24 and floating clamping members 27 can be reduced or increased.

[0069] Based on the above embodiments, in an optional embodiment of the present invention, such as Figures 1 to 3As shown, a multi-functional integrated displacement welding workstation also includes a third support member 7. The third support member 7 is slidably engaged with the first fixed base 1 or the first sliding base 5 to adjust the distance between the third support member 7 and the first support member 6. Specifically, the third support member 7 allows the flange to be fixed in a third position, thereby adapting to workpieces with irregularly shaped pipe fittings or workpieces requiring the installation of three flanges, greatly improving the versatility of the multi-functional integrated displacement welding workstation and having significant practical value.

[0070] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 5 As shown, the first support member 6, the second support member 10, and the third support member 7 each include a flange fixing seat 18, a flange positioning plate 15 engaged with the flange fixing seat 18 for supporting the flange, a flange center positioning pin 14 and a flange hole positioning pin 16 detachably engaged with the flange positioning plate 15, two flange pressure heads 17 movably engaged with the flange fixing seat 18, and a third drive mechanism 19 drively connected to the two flange pressure heads 17. The third drive mechanism 19 is adapted to drive the two flange pressure heads 17 closer to or further apart from each other.

[0071] The flange press head has a U-shaped structure. The end of the U-shaped structure is inclined downward and has a first chamfer, and the inner side of the U-shaped structure and the end are provided with a second chamfer to accommodate rhomboid, square and round flanges.

[0072] The flange positioning plate 15 is provided with a plurality of mounting holes 20 for flange hole positioning pins 16, which can install flange hole positioning pins 16 of different specifications in different positions to adapt to flanges of different specifications.

[0073] Specifically, the flanges are available in round, square, and diamond shapes, and can be clamped and fixed using a first and a second chamfer. Furthermore, the aforementioned structure of the first support member 6, the second support member 10, and the third support member 7 uses a flange center locating pin 14 to position the flange's center hole, a flange hole locating pin 16 to position the flange's angle, and then a flange pressing head 17 to further fix the flange, thereby ensuring a secure flange fixation.

[0074] In this embodiment, as Figure 5As shown, the flange fixing seat 18 of the first support member 6 is engaged with the first slide 5. The flange fixing seat 18 of the second support member 10 is engaged with the second slide 11. The third support member 7 also includes a flange traveling slide 13 that is slidably engaged with the first fixing seat 1. The flange fixing seat 18 of the third support member 7 is engaged with the flange traveling slide 13. The first slide 5 is provided with a plurality of first positioning holes. The third support member 7 is adapted to be engaged with the first slide 5 through the first positioning holes. Specifically, the movable design of the third support member 7 can accommodate workpieces of more specifications.

[0075] By positioning and fixing the first support member 6 and the third support member 7 to the first slide block 5, and positioning and fixing the second support member 10 to the second slide block 11, the positioning accuracy between flanges can be greatly improved, thereby improving production accuracy and making its production meet more precise requirements.

[0076] In other embodiments, the first support member 6 may be configured to be movably engaged with the first slide 5, and the second support member 10 may be configured to be movably engaged with the second slide 11. The present invention does not specifically limit this.

[0077] Based on the above embodiments, in an optional embodiment of the present invention, such as Figures 7 to 10 As shown, the first clamping member 24 and the floating clamping member 27 are movably engaged with the clamping base 32 to adapt to workpieces of different specifications.

[0078] The first clamping member 24 includes a third slide 25 movably engaged with the clamping base 32, and a first abutment 26 engaged with the third slide 25. The first abutment 26 is configured in a V-shape.

[0079] The floating clamping member 27 includes a fourth slide 28 movably engaged with the clamping base 32, a telescopic member 29 engaged with the fourth slide 28, and a second abutment member 30 engaged with the telescopic member 29. The second abutment member 30 has a V-shaped structure. The telescopic member 29 is constructed as a cylinder or a hydraulic cylinder.

[0080] Specifically, the first clamping member 24 and the floating clamping member 27 can move up and down on the clamping base 32 to adapt to workpieces of different heights. The V-shaped abutment allows for side contact with the pipe fitting. The engagement lugs securely fix the workpiece, and the assembly further allows the workpiece to be rotated to any angle and raised to any height for welding or grinding by workers or automated welding robots.

[0081] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 11 As shown, the clamping base 32 includes a first clamping seat 41 engaged with the displacement assembly 2, and a second clamping seat 42 hinged to the first clamping seat 41. The second clamping seat 42 is configured to rotate about a hinge axis by a preset angle. At least one of the first clamping members 24 and / or at least one of the floating clamping members 27 are engaged with the second clamping seat 42 to switch positions and angles as the second clamping seat 42 changes position.

[0082] Preferably, the preset angle is 180 degrees. The first clamping member 24 and the floating clamping member 27 are movable between the first clamping seat 41 and the second clamping seat 42.

[0083] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 1 Figure 2 and Figure 6 As shown, the multifunctional integrated displacement welding workstation also includes a fourth support component 8 and a fifth support component 9.

[0084] Both the fourth support member 8 and the fifth support member 9 include: a fifth slide 21 movably connected to the first fixed base 1, a sixth slide 22 movably connected to the fifth slide 21, and a support member 23 connected to the sixth slide 22.

[0085] The first slide 5, the second slide 11, and the fifth slide 21 move in the same direction. The sixth slide 22 moves in a direction perpendicular to the direction of movement of the fifth slide 21.

[0086] The fourth support member 8 and the fifth support member 9 facilitate the fixing of workpieces onto the multi-functional integrated displacement welding workstation. Specifically, the workpiece is placed on the fourth support member 8 and the fifth support member 9 and moved horizontally to embed the lifting lug into the lifting lug groove 40; then, the lifting lug is fixed by the lifting lug limiting member 31. This operation further simplifies the workpiece loading and unloading process, greatly improves production efficiency, and represents a significant advancement.

[0087] Based on the above embodiments, in an optional embodiment of the present invention, the first driving member 12 includes a first lead screw (not shown) rotatably engaged with the first fixed base 1, and a first motor (not shown) drively connected to the lead screw. The first slide 5 and the second slide 11 are respectively engaged with the first lead screw and are configured to move closer to or further away from each other when the lead screw rotates. Preferably, the multifunctional integrated displacement welding workstation further includes two laser marking components 3 respectively engaged with the two displacement components 2. The laser marking components 3 are adapted to mark reference lines on the workpiece.

[0088] This invention's multifunctional integrated displacement welding workstation, through the integration of a multifunctional mechanism, enables integrated operation of workpiece clamping and flange assembly. The floating clamping component 27 in the device can be driven by at least two pressure levels. Combined with the coordinated movement of the displacement component 2 and the slide, it can accurately correct the inward or outward deformation of the workpiece, ensuring the embedding accuracy of the pipe fitting and flange. Simultaneously, the lifting lug limiting component 31, through the design of elastic elements and floating pins, can adapt to lifting lugs of different thicknesses, preventing the pad from falling off when the clamp is released, thus improving clamping stability. Flange positioning employs a combination of quick-change templates and large-hole positioning pins. With the centering and clamping mechanism, the center distance tolerance between the two flanges can be controlled within ±0.1mm, the flatness and parallelism within ±0.5mm and 0.1mm respectively, and the perpendicularity error not exceeding 3‰, significantly improving the geometric accuracy of flange assembly.
