The expansion head contains the support block, which is frustoconical in shape. The support block is mounted on the top of the push rod, and a coupling is rotatably mounted on the bottom of the push rod. The coupling is connected to the piston rod of the second cylinder. The second cylinder is fixed on a cylinder frame, which is fixed below the machine base. The second cylinder pushes the push rod upward, causing the push rod to lift the support block upward. The support block then expands outward, bringing it into contact with the inner wall of the center hole of the flange.

[0009] According to some embodiments of the present invention, the clamping mechanism further includes a chassis and a top plate located above the chassis, a column connecting the top plate and the chassis, and an insert block fixed in the center of the top surface of the top plate, the insert block being inserted into the center hole of the end cap; The top plate has holes, and the positions of the holes correspond to the positions of the water pipe holes on the end cap. The water pipe positioning assembly is mounted on the chassis.

[0010] According to some embodiments of the present invention, the water pipe positioning assembly includes a through rod, a lifting plate, a guide rod, and a cylinder three. The through rod is vertically fixed to the lifting plate. The lifting plate is connected to the piston rod of the cylinder three. The cylinder three is fixedly installed on the chassis.

The top end of the guide rod is connected to the lifting plate.

[0011] According to some embodiments of the present invention, the flange welding mechanism includes a gantry frame, a fixed frame, a lifting frame, a cylinder, a rotating tube, a rotating drive assembly, a pressure ring, and a welding gun.

[0013] The present invention has at least the following beneficial effects: 1. During equipment operation, the operator first places the end cap on the clamping mechanism and then places the flange at the flange welding position on the end cap. The rotary table automatically rotates, transporting the clamping mechanism to below the flange welding mechanism. The flange welding mechanism then starts, performing high-quality welding between the flange and the end cap. Subsequently, the rotary table continues to rotate, sending the workpiece to the water pipe welding station.

The water pipe welding robot completes the welding of the water pipe and the end cap. The entire process is continuous and automatic, significantly improving welding accuracy and production efficiency, while greatly reducing the labor intensity and errors of manual operation.

[0014] 2. After accurately placing the flange on the support ring, the expansion head is inserted into the center hole of the flange. Then, cylinder two activates, pushing the push rod upwards. The upward movement of the push rod, through the inclined surface structure on the connected support block, causes the expansion block to be subjected to radial outward thrust, gradually expanding outwards until the expansion block makes tight contact with the inner wall of the flange's center hole. This securely fixes the flange to the expansion head. Subsequently, motor two starts, driving the drive gear to rotate. The drive gear further drives the meshing gear disc to rotate, thereby achieving the overall rotation of the flange through the expansion head, ultimately completing the precise adjustment of the flange.

[0015] 3. After accurately placing the flange on the support ring, the expansion head is inserted into the center hole of the flange. Then, cylinder two begins to operate, pushing the push rod upwards. The upward movement of the push rod, through the inclined surface structure on the connected support block, causes the expansion block to be subjected to radial outward thrust, gradually expanding outwards until the expansion block makes tight contact with the inner wall of the flange's center hole. This securely fixes the flange to the expansion head. Subsequently, motor two starts, driving the drive gear to rotate. The drive gear further drives the meshing gear disc to rotate, thereby achieving the overall rotation of the flange through the expansion head, ultimately completing the precise adjustment of the flange.

Detailed Implementation

[0018] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] In the description of this invention, the terms "first," "greater than," "less than," and "exceeding" are understood to exclude the stated number. The use of "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the quantity of indicated technical features, or the order of the indicated technical features.

[0020] like Figures 1 to 3 As shown, the flange and water pipe welding equipment includes a rotary table 100, a clamping mechanism 200, a flange welding mechanism 300, and a water pipe welding robot 400. The clamping mechanism 200 is installed on the rotary table 100 and is used to accurately position and fix the end cap to be welded. It includes a water pipe positioning component 210. The flange welding mechanism 300 and the water pipe welding robot 400 are respectively arranged on both sides of the periphery of the rotary table 100 to realize multi-station collaborative operation.

[0021] During equipment operation, the operator first places the end cap on the clamping mechanism 200 and positions the flange at the flange welding position on the end cap. The rotary table 100 automatically rotates, transporting the clamping mechanism 200 below the flange welding mechanism 300. The flange welding mechanism 300 then starts, performing high-quality welding between the flange and the end cap. Subsequently, the rotary table 100 continues to rotate, delivering the workpiece to the water pipe welding station. At this point, the water pipe positioning component 210 inserts the water pipe into the corresponding welding hole on the end cap and fixes it in place. The water pipe welding robot 400 then completes the welding of the water pipe and the end cap. The entire process is continuous and automatic, significantly improving welding accuracy and production efficiency while greatly reducing the labor intensity and errors of manual operation.

[0022] Reference Figure 1 , 12 As shown, the equipment is also equipped with a storage rack 500 and a high-efficiency material handling mechanism 600. The storage rack 500 is located on one side of the flange welding mechanism 300 to facilitate the storage and transfer of flanges. The material handling mechanism 600 is precisely installed above the storage rack 500, which can reliably remove the flange from the storage rack 500 and accurately place it on the flange welding position on the end cover, thereby realizing the continuity and automation of the production process.

[0023] To further improve welding accuracy, the equipment is also equipped with a directional adjustment mechanism 700, located between the storage rack 500 and the flange welding mechanism 300. After the material handling mechanism 600 removes the flange from the storage rack 500, it first places it on the directional adjustment mechanism 700, which then adjusts the angle and direction of the flange according to process requirements to ensure the accuracy of the welding position.

[0024] Reference Figure 13 As shown, the specific structure of the material handling mechanism 600 includes a stand 630, a moving plate 640, a moving drive assembly 650, a material handling assembly one 610, and a material handling assembly two 620.

[0025] Material handling component 610 precisely picks up the flange from the storage rack 500 and smoothly moves it above the aligning mechanism 700, then places it on the aligning mechanism 700. Subsequently, the aligning mechanism 700 activates, adjusting the flange to a preset orientation through rotation, ensuring its orientation meets subsequent assembly requirements. After alignment, material handling component 620 quickly intervenes, reliably removing the aligned flange from the aligning mechanism 700 and accurately placing it in the designated position on the end cap. This series of continuous and coordinated actions achieves an efficient and uninterrupted automated flange feeding process on the production line.

[0026] Among them, the material handling component 610 includes a cylinder 611, a first finger cylinder, and a gripper 613; the material handling component 620 includes a second finger cylinder, a lifting slide 623, and a gripper 624.

[0027] Specifically, the movable plate 640 is vertically mounted on the side of the crossbeam of the upright 630 via a sliding assembly. The sliding assembly includes a slide rail and a slider slidably mounted on the slide rail. The slide rail is horizontally fixed to the side of the crossbeam, and the slider is fixed to the back of the movable plate 640.

[0028] The moving plate 640 is driven by the moving drive assembly 650 to achieve horizontal reciprocating motion. The moving drive assembly 650 includes a servo motor 651, a drive gear and a rack 652. The motor 651 is fixed to the moving plate 640, the drive gear is mounted on the drive shaft of the motor 651, and the drive gear meshes with the rack 652 fixed to the side of the crossbeam.

[0029] Driven by motor 651, the drive gear rotates, enabling it to translate along a fixed rack 652. Motor 651 changes the direction of rotation, allowing the drive gear to move not only to the left but also in the opposite direction, thus achieving reciprocating motion along the rack 652. This reciprocating motion further drives the moving plate 640 to reciprocate horizontally, completing the predetermined mechanical action. The entire process, through precise control of the drive gear by the motor, ensures the smoothness and accuracy of the moving plate 640's movement.

[0030] In the automated equipment, a cylinder 611 is specifically installed on the moving plate 640. Its piston rod is mechanically connected to a first finger cylinder, which is equipped with a gripper 613 for precise gripping operations. During the material handling process, cylinder 611 first descends, pushing the gripper 613 to accurately move to both sides of the flange to be picked up. Subsequently, the first finger cylinder drives the gripper 613 to move in opposite directions, firmly clamping the outer edge of the flange to ensure stable and reliable gripping. After completing the material handling action, cylinder 611 moves upward, smoothly moving the gripped flange away from the storage rack 500, preparing it for subsequent placement of the flange in the adjusting mechanism 700.

[0031] Meanwhile, a lifting slide 623 is fixed on the movable plate 640, and an inclined plate 622 is installed on the lifting slide 623. The inclined plate 622 facilitates the passage of the flange welding mechanism 300 so that its lowest end extends above the clamping mechanism 200. A second finger cylinder is installed at the lowest end of the inclined plate 622, and the second finger cylinder is equipped with a second gripper 624. During the unloading process, the lifting slide 623 first lowers the inclined plate 622, pushing the second gripper 624 to accurately move to the two sides of the flange to be picked up; then, the second finger cylinder drives the second gripper 624 to move in opposite directions, firmly gripping the outer edge of the flange, ensuring stable and reliable gripping. After the picking action is completed, the lifting slide 623 moves the inclined plate 622 upward, causing the gripped flange to smoothly leave the adjusting mechanism 700, preparing for the subsequent placement of the flange on the end cover.

[0032] To further explain the operation of the material handling mechanism 600: 1. Cylinder 611 first descends, pushing gripper 613 to accurately move to both sides of the flange to be picked up; then, the first finger cylinder drives gripper 613 to move in opposite directions, firmly clamping the outer edge of the flange to ensure stable and reliable gripping. After the picking action is completed, cylinder 611 immediately moves upward, causing the gripped flange to smoothly leave the storage rack 500. 2. The drive gear starts to rotate under the driving action of the motor 651, so that the drive gear can move along the rack 652, thereby driving the moving plate 640 to move towards the adjusting mechanism 700, so that the grasped flange moves above the adjusting mechanism 700. 3. Cylinder 611 begins to move downwards to lower the position, accurately placing the flange on the working surface of the directional mechanism 700. Then, the first finger cylinder executes the release command, and the gripper 613 releases its grip on the workpiece, completing the first unloading action. Cylinder 611 starts the lifting program, quickly moving upwards back to the initial position. Motor 651 then starts, causing the moving plate 640 to reset and move, preparing for the next operation cycle. 4. The directional adjustment mechanism allows for 700 pairs of flanges to rotate and adjust. 5. After the rotation and reversal are completed, cylinder 611 begins to move downward to lower gripper 613, so that gripper 613 can grab the flange on storage rack 500 again; at the same time, lifting slide 623 lowers inclined plate 622, so that gripper 624 grabs the flange on both sides of reversal mechanism 700. 6. Motor 651 is then restarted, and the moving plate 640 begins to move, causing the flange gripped by gripper 613 to move above the directional mechanism 700, while the flange gripped by gripper 624 moves above the end cover; at this time, cylinder 611 and lifting slide 623 work simultaneously, so that the two flanges are placed on the directional mechanism 700 and the end cover respectively. 7. After placement is completed, cylinder 611 and lifting slide 623 are reset, and motor 651 is started to move the moving plate 640 to prepare for the next operation cycle. 8. Repeat the above steps.

[0033] Through the above actions, uninterrupted feeding of flanges can be achieved during processing and assembly, thereby significantly reducing production downtime and improving equipment utilization and overall work efficiency.

[0034] Reference Figures 14 to 17 As shown, the steering mechanism 700 includes a machine base 710, a turntable 720, a tensioning head 720, a support ring 730, a support block 740, a push rod 750, a second cylinder 760, and a second motor 770. The support block 740 is frustum-shaped.

[0035] The machine base 710 is equipped with a bearing sleeve, in which the push rod 750 is rotatably installed. The upper section of the push rod 750 is fitted with a gear disk 7100, which is fixedly connected to the bottom of the tension head 720. The tension head 720 is fitted with a support ring 730. The tension head 720 is designed as multiple ring-shaped expansion blocks 721, with gaps 722 between the expansion blocks 721, and a conical support block 740 is installed in the middle.

[0036] The bottom end of the push rod 750 is rotatably equipped with a coupling 780, which is connected to the piston rod of cylinder 760. Cylinder 760 is fixed on cylinder frame 790, which is fixed below machine base 710.

[0037] The gear disk 7100 meshes with the drive gear 7200, which is mounted on the drive shaft of the motor 770.

[0038] After the flange is accurately placed on the support ring 730, the tightening head 720 is inserted into the center hole of the flange. Then, the cylinder 760 starts to move, pushing the push rod 750 upward. The rise of the push rod 750, through the inclined surface structure on the support block 740 connected to it, causes the expansion block 721 to be pushed radially outward, thus gradually expanding outward until the expansion block 721 makes tight contact with the inner wall of the flange center hole. In this way, the flange is firmly fixed to the tightening head 720. Subsequently, the motor 770 starts, driving the drive gear 7200 to rotate. The drive gear 7200 further drives the gear disk 7100 meshing with it to rotate, thereby realizing the overall rotation of the flange through the tightening head 720, and finally completing the precise adjustment of the flange.

[0039] Reference Figures 4 to 7 As shown, the clamping mechanism 200 also includes a base 220, a top plate 230, and a connecting column 240. A plug 250 is provided in the center of the top plate 230, which is used to insert into and fix the center hole of the end cap. The top plate 230 has a hole 231 corresponding to the water pipe hole of the end cap. The water pipe positioning assembly 210 is installed below the base 220 and can pass upwards through the hole 231 to achieve water pipe positioning.

[0040] The positioning assembly consists of a through rod 211, a lifting plate 212, a guide rod 213, and a cylinder 214. The through rod 211 is vertically fixed to the lifting plate 212. The lifting plate 212 is connected to the piston rod of the cylinder 214. The cylinder 214 drives the lifting plate 212 to achieve lifting and lowering movement. A locking block 215 is detachably installed on the upper part of the through rod 211. A guide sleeve 216 is installed on the chassis 220. The guide rod 213 is installed inside the guide sleeve 216. The top end of the guide rod 213 is connected to the lifting plate 212. The cooperation between the guide rod 213 and the guide sleeve 216 ensures that the lifting and lowering process is stable and accurate.

[0041] During operation, cylinder 3 214 starts and pushes the lifting plate 212 upward. The lifting plate 212 rises accordingly, causing the through rod 211 to move upward synchronously. As the through rod 211 rises, it passes precisely through the pre-set hole 231 and the water pipe hole on the end cap. At this time, the operator fits the water pipe onto the outside of the through rod 211 and installs the clamp 215 at the designated position on the through rod 211, so that the clamp 215 is firmly pressed against the end of the water pipe, that is, the top of the water pipe, ensuring that the water pipe fits tightly against the surface of the end cap, thereby achieving accurate positioning and reliable fixation of the water pipe.

[0042] After the water pipe welding process is completed, the staff only needs to remove the clamp 215, and then the cylinder 214 will reset, driving the through rod 211 to retract downwards, so that the end cap of the water pipe that has been welded can be easily removed.

[0043] Reference Figures 8 to 11 As shown, the flange welding mechanism 300 adopts a gantry frame 310 structure, on which a fixed frame 320, a lifting frame 330, a cylinder 340, a rotating tube 350, a rotating drive assembly 360, a pressure ring 370, and a welding gun 380 are mounted. The fixed frame 320 is mounted on the crossbeam of the gantry frame 310, and the cylinder 340 drives the lifting frame 330 to move up and down. The rotating tube 350 is mounted on the lifting frame 330 and is driven to rotate by the rotating drive assembly 360. The bottom of the rotating tube 350 is equipped with a mounting bracket 390 with a pressure ring 370. The pressure ring 370 is used to clamp the flange, and the welding gun 380 is fixed to one side of the mounting bracket 390.

[0044] The rotary drive assembly 360 includes a motor 361, a gear 362, and a gear 363. The motor 361 is securely mounted on the lifting frame 330. The gear 362 is mounted on the drive shaft of the motor 361. The gear 362 and the gear 363 mesh with each other to form a transmission relationship. The gear 363 is mounted on the rotary tube 350, thereby realizing the effective driving and precise control of the rotary tube 350.

[0045] During the flange welding operation, cylinder 340 drives the lifting frame 330 to move steadily downwards, ensuring that the pressure ring 370 is evenly and reliably pressed against the flange surface, guaranteeing that the flange position is fixed and does not shift during welding. Simultaneously, motor 361 starts operating, transmitting power to gear 363 through precisely meshing gear 362, which in turn drives the rotating tube 350 to rotate smoothly. This rotation allows the welding torch mounted on the rotating tube 350 to make continuous and uniform circular motions around the flange circumference, achieving full-circumference welding. The entire process is precisely controlled and coordinated, effectively ensuring the uniformity of the weld and the reliability of the weld joint.

[0046] To further improve processing efficiency, four workstations are provided on the rotary table 100, and two clamping mechanisms 200 are installed on each of the four workstations. At the same time, on the periphery of the rotary table 100 along the rotation direction of the rotary table 100, i.e., in the counterclockwise direction, there are end cap loading position, flange welding position, water pipe loading position, and water pipe welding position.

[0047] The flange welding position is equipped with a flange welding mechanism 300, and the water pipe welding robot 400 is set at the water pipe welding position; the workers load the water pipe at the water pipe loading position, place the end pipe at the end cap loading position, and remove the end cap after the flange and water pipe welding are completed.

[0048] Further explanation of the welding work on the equipment: 1. The worker places the end cover to be welded on the top plate 230 at the end cover loading position, so that the support block 740 is inserted and fixed in the center hole of the end cover. The rotary table 100 starts to rotate counterclockwise, so that the end cover is rotated to the flange welding mechanism 300. 2. Cylinder 611 first descends, pushing gripper 613 to accurately move to both sides of the flange to be picked up; then, the first finger cylinder drives gripper 613 to move in opposite directions, firmly clamping the outer edge of the flange to ensure stable and reliable gripping. After the picking action is completed, cylinder 611 immediately moves upward, causing the gripped flange to smoothly leave the storage rack 500. 3. The drive gear starts to rotate under the driving action of the motor 651, so that the drive gear can move along the rack 652, thereby driving the moving plate 640 to move towards the adjusting mechanism 700, so that the flange being grabbed is moved above the adjusting mechanism 700. 4. Cylinder 611 begins to move downwards to lower the position, accurately placing the flange on the working surface of the directional mechanism 700. Then, the first finger cylinder executes the release command, and the gripper 613 releases its grip on the workpiece, completing the first unloading action. Cylinder 611 starts the lifting program and quickly moves upwards back to the initial position. Motor 651 then starts, causing the moving plate 640 to reset and move, preparing for the next operation cycle. 5. After the flange is accurately placed on the support ring 730, the tightening head 720 is inserted into the center hole of the flange. Then, the cylinder 760 starts to move, pushing the push rod 750 upward. The rise of the push rod 750, through the inclined surface structure on the support block 740 connected to it, causes the expansion block 721 to be pushed radially outward, thus gradually expanding outward until the expansion block 721 makes tight contact with the inner wall of the flange center hole. In this way, the flange is firmly fixed to the tightening head 720. Subsequently, the motor 770 starts, driving the drive gear 7200 to rotate. The drive gear 7200 further drives the gear disk 7100 meshing with it to rotate, thereby realizing the overall rotation of the flange through the tightening head 720, and finally completing the precise adjustment of the flange.

[0049] 6. After the rotation and reversal are completed, cylinder 611 begins to move downward to lower gripper 613, so that gripper 613 can grab the flange on storage rack 500 again; at the same time, lifting slide 623 lowers inclined plate 622, so that gripper 624 grabs the flange on both sides of reversal mechanism 700. 7. Motor 651 is then restarted, and the moving plate 640 begins to move, causing the flange gripped by gripper 613 to move above the directional mechanism 700, while the flange gripped by gripper 624 moves above the end cover; at this time, cylinder 611 and lifting slide 623 work simultaneously, so that the two flanges are placed on the directional mechanism 700 and the end cover respectively. 8. After placement is completed, cylinder 611 and lifting slide 623 are reset, motor 651 is started, and moving plate 640 is reset and moved to prepare for the next operation cycle. Material picking mechanism 600 repeats the above picking action. 9. Begin flange welding. Cylinder 4 340 drives the lifting frame 330 to move steadily downwards, ensuring that the pressure ring 370 is evenly and reliably pressed against the flange surface, guaranteeing that the flange position is fixed and does not shift during welding. Simultaneously, motor 361 starts operating, transmitting power to gear 2 363 through precisely meshed gear 1 362, which in turn drives the rotating tube 350 to rotate smoothly. This rotation allows the welding torch mounted on the rotating tube 350 to make continuous and even circular motions around the flange circumference, thus achieving full-circumference welding. 10. After the flange welding operation is completed, the rotary table 100 rotates counterclockwise again to rotate the end cover with the welded flange to the water pipe loading position. 11. The staff begins to feed the water pipe. First, cylinder 3 214 is started and pushes the lifting plate 212 upward. The lifting plate 212 rises and drives the through rod 211 to move upward in sync. As the through rod 211 rises, it will pass through the pre-set hole 231 and the water pipe hole on the end cap in sequence. At this time, the staff will put the water pipe on the outside of the through rod 211 and install the clamp 215 in the designated position of the through rod 211 so that the clamp 215 presses the water pipe from above. 12. After the water pipe loading operation is completed, the rotary table 100 rotates counterclockwise again, so that the end cap with the pre-installed water pipe is rotated to the water pipe welding robot 400 for water pipe welding. 13. After the water pipe welding operation is completed, the rotary table 100 rotates counterclockwise again so that the end caps with completed flange and water pipe welding return to the end cap loading position. After the workers remove the finished product, they place the end caps to be welded on the top plate 230; and repeat the above actions.

[0050] This enables rapid, precise, and fully automated welding of the flange on the end cap to the water pipe, making it suitable for mass production and offering significant advantages such as high consistency, high production efficiency, and low operational difficulty.
