Description

Technical Field

[0001] This invention relates to the field of water supply pipeline welding technology, specifically to a multi-functional integrated automated welding workstation for water supply pipeline installation. Background Technology

[0002] In urban water supply and industrial fluid transportation, the installation quality of water supply pipelines directly determines the operational stability and service life of the pipeline network system. Pipeline welding, as a core process in installation, has a crucial impact on the construction cycle and operation and maintenance costs of the entire water supply project due to its welding efficiency, weld quality, and level of automation. Currently, water supply pipeline welding is generally carried out using manual welding or single-function automated equipment, which has the following drawbacks:

[0003] Existing welding equipment often uses fixed-specification clamping mechanisms. When changing pipe diameters, tooling fixtures need to be disassembled and replaced, resulting in long changeover times. This makes it difficult to adapt to the mixed installation of multiple pipe specifications on construction sites. Furthermore, the clamping process cannot synchronously move the pipes relative to each other, and the positional deviation during manual loading cannot be compensated for by automated movement. This leads to poor alignment accuracy between the weld and the welding torch, easily resulting in defects such as weld misalignment, uneven weld reinforcement, and incomplete penetration. Additionally, the grinding disc can only rotate or move in one direction, unable to achieve left-right reciprocating oscillation. For the bevel sides of circumferential welds and the edge areas of the weld reinforcement, it is difficult to form a uniform grinding trajectory, easily leaving oxide scale, weld beads, and spatter. Moreover, the fixed contact area between the grinding disc and the weld results in concentrated grinding pressure per unit area, causing grinding marks of varying depths on the weld surface. The roughness cannot meet the requirements for the smoothness of the inner wall of water supply pipes. Furthermore, single-track grinding requires a longer time to cover the entire weld area and lacks the function of adjusting the oscillation amplitude according to the pipe diameter; the fixed amplitude cannot match welds of different widths.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0010] Preferably, the lower end of the lead screw extends into the interior of the protective cylinder, the threaded sleeve is fitted on the outer side of the lower end of the lead screw, and the threaded sleeve and the lead screw are connected by a thread, and the upper end of the limiting rod extends out of the outer surface of the protective cylinder.

[0011] Preferably, a fixing plate is fixed at an equal angle to the side of the clamping roller inside the base, and a wedge block is fixedly connected between the lower side of the fixing plate and the side of the clamping roller.

[0012] Preferably, the dust hood is fixedly installed on the sides of the two upper connecting plates by a horizontal plate, and the left side inside the dust hood is rotatably connected to a mounting plate by a shaft. The left side of the mounting plate is bolted to a fourth motor, and the output end of the fourth motor is fixedly connected to the top of the grinding disc by a shaft.

[0015] Preferably, the guide block and the abutment rod are positioned correspondingly, and the bottom of the abutment rod is in contact with the inclined surface of the guide block.

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

[0017] 1. This invention, through a multi-stage linkage transmission structure of "motor, gear, bevel gear, threaded rod and threaded sleeve", can drive multiple sets of clamping rollers to synchronously retract inward or open outward. Without the need to change special tooling, it can adapt to the clamping and fixing requirements of water supply pipes of different diameters, greatly reducing the tooling replacement cost and operation preparation time, and improving the versatility of the equipment.

[0018] 2. In the process of moving the clamping roller, the inclined surface extrusion transmission characteristics of the wedge block on the fixed plate and the support frame are used to drive the clamping roller to generate horizontal displacement synchronously. While realizing the clamping and fixing of the pipe, the precise coaxial alignment of the two sections of pipe to be welded is completed simultaneously. This abandons the traditional step-by-step operation mode of "clamping first and then centering", eliminates the positioning error caused by step-by-step operation, and provides a reliable guarantee for the subsequent welding quality.

[0019] 3. This invention uses a motor to drive the grinding disc to rotate, which, in conjunction with the rotation of the pipeline, achieves uniform grinding of the circumferential weld seam from all directions. Simultaneously, an integrated dust collection system collects grinding chips and welding fumes, preventing the spread of pollutants. Furthermore, the eccentric compression of the eccentric block causes the grinding disc and dust collection head to oscillate back and forth, expanding the work coverage area. The dust collection head automatically extends through the cooperation of the guide block and the contact rod, compensating for oscillation displacement deviations and ensuring stable and reliable dust collection performance.

[0020] 4. This invention integrates the grinding and dust collection components with the pipe clamping mechanism. As the clamping rollers adapt to the pipe diameter, they simultaneously drive the grinding disc and the dust collection head to radially displace, achieving adaptation to pipes of different diameters. Furthermore, utilizing a trapezoidal eccentric block structure that is wider at the top and narrower at the bottom, the swing amplitude is positively correlated with the pipe diameter; larger pipe diameters correspond to larger swing amplitudes, and smaller pipe diameters correspond to smaller swing amplitudes, ensuring consistent grinding quality and dust collection performance for pipes of different sizes.

[0031] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0032] Please see Figure 1 - Figure 9This invention provides a technical solution: a multi-functional integrated automated welding workstation for water supply pipeline installation, comprising a base 1, control cabinets 2 movably mounted on both sides of the upper surface of the base 1, and three-jaw chucks 3 provided on the opposite faces of the two control cabinets 2; a first motor 4 fixed on the left side of the base 1, and a bidirectional threaded rod 5 fixed to the output end of the first motor 4; and movable plates 6, both movable plates 6 being threadedly connected to the outer sides of both ends of the bidirectional threaded rod 5, the bidirectional threaded rod 5 being bearing connected inside the base 1, and the outer threads at both ends of the bidirectional threaded rod 5 having opposite directions; the bottoms of the two movable plates 6 being slidably connected to the inner wall of the base 1; a welding torch 12 being disposed inside a dust extraction hood 20; and hydraulic cylinders 7 being mounted on the upper surface of the movable plates 6, the telescopic ends of the hydraulic cylinders 7 being bolted to a bearing plate 8, and the upper surface of the bearing plate 8 being rotatably connected. A bearing roller 9 is attached, and a protective cylinder 10 is fixed in the middle of the upper surface of the base 1. A cylinder 11 is bolted to the outside of the protective cylinder 10. A welding gun 12 is installed at the telescopic end of the cylinder 11. Adaptive clamping and centering components are set at both ends inside the protective cylinder 10. An adaptive swing component is set at the top inside the protective cylinder 10. A dust hood 20 is set at the top inside the protective cylinder 10. A grinding disc 17 and a dust suction head 18 are respectively connected to the left and right sides inside the dust hood 20. The dust hood 20 is fixedly installed on the sides of the two connecting plates 1312 above by a horizontal plate. A mounting plate 15 is rotatably connected to the left side inside the dust hood 20 by a shaft. A fourth motor 16 is bolted to the left side of the mounting plate 15. The output end of the fourth motor 16 is fixedly connected to the top of the grinding disc 17 by a shaft. The side of the dust suction head 18 is connected to an external dust collection device through a connecting pipe 19.

[0033] In one embodiment of the present invention, during operation, the operator inserts two sections of water supply pipe to be welded into the protective cylinder 10. The self-adaptive clamping and centering assembly built into the protective cylinder 10 clamps and coaxially centers the connecting ends of the two pipe sections. Then, two three-jaw chucks 3 are moved relative to each other, and a command is issued through the control cabinet 2 to activate the three-jaw chucks 3. The three-jaw chucks 3 then perform a secondary clamping and fixing of the non-connecting ends of the two pipe sections, ensuring the overall clamping stability of the pipes. After clamping, the operator activates the first motor 4 through the control cabinet 2. The first motor 4 drives the bidirectional threaded rod 5 to rotate, causing the two movable plates 6 on the bidirectional threaded rod 5 to move horizontally in opposite directions or away from each other. This precisely adjusts the distance between the two sets of bearing rollers 9 to match the current pipe diameter. After the distance is adjusted, the hydraulic cylinder 7 is activated, driving the bearing plate 8 and the bearing rollers 9 to rise synchronously until the bearing rollers 9 are tightly fitted against the outer wall of the water supply pipe, providing stable support for the subsequent rotational welding of the water supply pipe. Finally, the operator issues welding commands through the control cabinet 2. The welding torch 12 is started and the preset welding program is triggered. The welding torch 12 automatically welds the butt weld of the two sections of water supply pipes according to the set trajectory. During the welding process, the three-jaw chuck 3 drives the water supply pipe to rotate at a constant speed, so that the welding torch 12 can perform continuous and uniform full welding operation on the circumferential weld, ensuring the quality of the weld formation. After the welding is completed, the fourth motor 16 drives the grinding disc 17 to rotate at high speed. Combined with the uniform rotation of the water supply pipe itself, the circumferential weld of the pipe can be uniformly ground from all directions without dead angles. At the same time, the dust collection system is turned on to collect the dust. The negative pressure adsorption effect of the dust head 18 and the connecting pipe 19 collects the iron filings generated during grinding and the residual fumes from the welding process in one integrated manner, preventing pollutants from spreading to the working environment. Finally, after the water supply pipe is welded, the three-jaw chuck 3 is released and moves in the opposite direction to release the fixation on the end of the water supply pipe. Then, the second motor 1301 drives the rotating rod 1302 to rotate in the opposite direction, causing multiple clamping rollers 1306 to move outward and reset, releasing the fixation on the middle of the water supply pipe. At this time, the operator can take out the welded water supply pipe.

[0034] The adaptive clamping and centering assembly includes a second motor 1301, which is bolted to the outside of the protective cylinder 10. A rotating rod 1302 is fixed to the output end of the second motor 1301. A drive gear 1303 is fitted and fixed to the outer sides of both ends of the rotating rod 1302. Driven gear rings 1304 are fitted to the outer sides of both ends of the protective cylinder 10, and bevel gear rings 1307 are fixed to the opposite sides of the two driven gear rings 1304. Connecting plates 1312 are equidistantly arranged at the left and right ends inside the protective cylinder 10. A clamping roller 1306 is slidably connected to the lower surface of the connecting plate 1312 via a slider. A first return spring 1305 is installed between the end of the slider and the groove of the connecting plate 1312. A threaded sleeve 1310 and a limiting rod 1311 are fixed to the left and right sides of the upper surface of the connecting plate 1312, respectively. The outer wall of the protective cylinder 10 is located... A lead screw 1308 is connected to the side of the bevel ring 1307 by an equal-angle bearing, and a bevel gear 1309 is fixedly sleeved on the outer side of the upper end of the lead screw 1308. The driving gear 1303 and the driven gear ring 1304 are meshed, and the driven gear ring 1304 and the protective cylinder 10 are rotatably connected. The bevel gear 1309 and the bevel ring 1307 are meshed. The lower end of the lead screw 1308 extends into the interior of the protective cylinder 10. The threaded sleeve 1310 is sleeved on the outer side of the lower end of the lead screw 1308, and the threaded sleeve 1310 and the lead screw 1308 are threadedly connected. The upper end of the limiting rod 1311 extends out of the outer surface of the protective cylinder 10. A fixing plate 1313 is fixed at an equal angle to the side of the clamping roller 1306 inside the base 1, and a wedge block 1314 is fixedly connected between the lower side of the fixing plate 1313 and the side of the clamping roller 1306.

[0035] In one embodiment of the present invention, two sections of water supply pipe to be welded are simultaneously inserted into the protective cylinder 10 from both ends. The second motor 1301 is started, which drives two drive gears 1303 to rotate synchronously via a rotating rod 1302. The drive gears 1303 then drive the driven gear ring 1304 meshing with them to rotate. The bevel gear ring 1307 integrated on the driven gear ring 1304 rotates synchronously, thereby driving multiple bevel gears 1309 meshing with it to rotate synchronously. The rotational motion of the bevel gears 1309 is converted into the rotation of the lead screw 1308, driving the threaded sleeve 1310 to move axially. The multiple threaded sleeves 1310 are linked together, driving multiple... The clamping roller 1306 retracts inward synchronously to achieve adaptive clamping and fixing of the outer wall of water supply pipes of different diameters. At the same time, during the inward movement of the clamping roller 1306, the wedge block 1314 on the fixing plate 1313 and the wedge block 1314 on the clamping roller 1306 press against each other. Utilizing the inclined transmission characteristics of the wedge block 1314, the clamping roller 1306 is driven to generate horizontal displacement synchronously. Ultimately, the dual functions of clamping and fixing water supply pipes of different sizes and accurately centering and moving the two pipe sections are achieved. Furthermore, the first reset spring 1305 can drive the clamping roller 1306 to reset when the two wedge blocks 1314 are not pressing against each other.

[0036] The adaptive oscillation assembly includes a third motor 1401, which is bolted to the top of the inner wall of the protective cylinder 10. The output end of the third motor 1401 is rotatably connected to an eccentric block 1403 via a shaft. A fixed cylinder 1407 is rotatably connected to the inside of the dust hood 20 via a shaft. Adhesive blocks 1404 are fixed to the outer side of the fixed cylinder 1407 and the upper right side of the mounting plate 15. A guide block 1405 is fixed to the right side of the suction head 18. The eccentric block 1403 is located inside the dust hood 20 and is wider at the top and narrower at the bottom. The outer side of 3 is attached to the ends of the two fitting blocks 1404. The top of the suction head 18 extends into the interior of the fixed cylinder 1407, and a second return spring 1402 is installed between the top of the suction head 18 and the inner wall of the fixed cylinder 1407. The top of the inner wall of the dust cover 20 is fixedly connected to the right side of the fixed cylinder 1407 with an abutment rod 1406. The guide block 1405 is positioned corresponding to the abutment rod 1406, and the bottom of the abutment rod 1406 is attached to the inclined surface of the guide block 1405. Torsion springs are installed between the outer side of the fixed cylinder 1407 and the shaft end of the mounting plate 15 and the inner wall of the dust cover 20.

[0037] In one embodiment of the present invention, the third motor 1401 drives the eccentric block 1403 to rotate. Utilizing the eccentric structural characteristics of the eccentric block 1403, it reciprocates by pressing the mounting plate 15 against the contact block 1404 on the fixed cylinder 1407, causing the grinding disc 17 and the suction head 18 to reciprocate synchronously, expanding the coverage area of ​​grinding and suction. During the swinging process of the suction head 18, the guide block 1405 on its side is pressed by the abutment rod 1406, driving the suction head 18 to automatically extend, thereby compensating for the positional deviation during the swinging process and ensuring that the suction effect is not affected by the swinging motion. The grinding and dust collection components are linked with the pipe clamping mechanism, so when the clamping roller 1306 adaptively retracts or opens according to different pipe diameters of water supply pipes, it can simultaneously drive the grinding disc 17 and the dust collection head 18 to perform radial displacement, thus achieving adaptation to pipes of different sizes. Furthermore, because the eccentric block 1403 has a trapezoidal structure that is wider at the top and narrower at the bottom, its swing stroke is positively correlated with the pipe diameter. The swing amplitude is larger for large-sized water supply pipes and correspondingly smaller for small-sized water supply pipes, ensuring the consistency of grinding and the effectiveness of dust collection for pipes of different diameters.

[0038] Working Principle: When using this multi-functional integrated automated welding workstation for water supply pipeline installation, firstly, two sections of water supply pipeline to be welded are simultaneously inserted from both ends of the protective cylinder 10. The built-in adaptive clamping and centering component is activated: the second motor 1301 drives the transmission structure, causing multiple clamping rollers 1306 to retract inwards, achieving adaptive clamping of pipelines with different diameters; simultaneously, the wedge block 1314 extrudes and drives the clamping rollers 1306 to move horizontally, completing precise centering of the two pipeline sections. The first return spring 1305 is responsible for resetting the clamping rollers 1306; then, the three-jaw chuck 3 is activated via the control cabinet 2 to perform secondary clamping of the non-connected ends of the pipeline; next, the first motor 4 is activated to adjust the spacing of the bearing rollers 9 to match the pipe diameter, and the hydraulic cylinder 7 drives the bearing rollers 9 to lift and fit against the outside of the pipeline. The wall provides welding support; after the welding command is issued, the welding torch 12 welds according to the preset trajectory, and the three-jaw chuck 3 drives the pipe to rotate at a constant speed to complete the continuous full welding of the circumferential weld; after the welding is completed, the fourth motor 16 drives the grinding disc 17 to rotate, and grinds the weld in conjunction with the rotation of the pipe; the dust collection system is turned on at the same time, and collects iron filings and fumes through the dust collection head 18; at the same time, the third motor 1401 drives the eccentric block 1403 to rotate, which drives the grinding disc 17 and the dust collection head 18 to swing back and forth to expand the working range; the dust collection head 18 automatically extends to compensate for displacement when swinging, ensuring the dust collection effect; the grinding and dust collection component is linked with the clamping mechanism, and can adaptively adjust the radial position according to the pipe diameter, and the trapezoidal structure of the eccentric block 1403 makes the swing amplitude positively correlated with the pipe diameter, ensuring the consistency of grinding and dust collection for different pipe diameters.
