Description

Technical Field

[0001] The present invention relates to the technical field of middle groove welding, and in particular to an automatic flip-over middle groove welding device. Background Art

[0002] The middle trough is the core component of the scraper conveyor. Its structure is usually welded by the trough side steel and the middle plate to form a U-shaped or rectangular long trough body, which is mainly used to carry and transport bulk materials such as coal and ore. In industrial fields such as coal mining and metallurgy, scraper conveyors need to operate under heavy loads and strong wear environments for a long time. Therefore, the welding quality of the middle trough directly affects the service life and operational stability of the equipment. During the welding process, the welds of the middle trough must have high strength and high sealing properties to prevent material leakage and structural cracking. Since the middle trough can be several meters long, and the welding parts include the butt joints between the trough side steel and the middle plate, the connection seams between the baffle trough and the shovel plate trough, and other positions, precise positioning and stable clamping are required during welding, and welding smoke must be effectively handled to ensure welding accuracy and a safe operating environment.

[0003] However, the existing middle groove has the following shortcomings during the welding process:

[0004] First, when welding the central groove, multiple independent fixtures are commonly used. For example, manual or pneumatic fixtures are installed at the upper and lower edges of the groove steel and at the joint of the middle plate. Each fixture needs to be adjusted and locked separately. This multi-fixture fixing method is not only cumbersome, requiring operators to calibrate the position of each fixture one by one, but also affects welding accuracy due to the accumulation of multiple positioning errors. It also increases equipment cost and maintenance difficulty.

[0005] In addition, the smoke and dust generated during the welding process (including metal oxide particles, harmful gases, etc.) require additional independent smoke exhaust devices, such as installing a liftable smoke exhaust hood above the welding area or installing an exhaust duct on the side of the workbench. These smoke exhaust devices need to be separately connected to the fan, filter device and pipe, resulting in a complex welding device structure. The smoke exhaust components and fixtures are prone to spatial interference. The operator needs to frequently adjust the position of the smoke exhaust hood, further reducing welding efficiency.

[0006] This traditional solution of "multiple fixtures + independent smoke exhaust" has become difficult to adapt to the needs of modern industrial production for efficient and automated welding due to its cumbersome structure and complex operation. Summary of the Invention

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Reference Figures 1-11 , Example 1, an automatic flip type middle groove welding device, including a base 1, the top outer wall of the base 1 is fixedly connected to the welding flip frame 2 by screws, and the top of the inner side of the welding flip frame 2 is provided with a welding table 3, the center of the top outer wall of the welding table 3 is rotatably connected to the main shaft 4 through a bearing, and a connecting plate 5 is welded on the outer wall of the main shaft 4, both ends of the bottom outer wall of the connecting plate 5 are rotatably connected to a connecting rod 6, and the outer wall of one end of the connecting rod 6 is rotatably connected to a clamping plate 7, a limiting column 8 is penetrated on the inner wall of the clamping plate 7, and the top outer wall of the limiting column 8 is rotatably connected to a compensation clamping plate 9;

[0038] The top outer wall of the welding table 3 is fixedly connected to a symmetrically distributed slide rail 26 by screws, and the clamping plates 7 are slidably connected to the top outer wall of the slide rail 26. A middle groove is placed between the two clamping plates 7, wherein the two clamping plates 7 are attached to both sides of the middle groove, and the two compensating clamping plates 9 are attached to both sides of the middle groove;

[0039] The welding table 3 includes a frame plate 301, an inner plate 302 and an inclined plate 303, wherein the frame plate 301 is arranged on the top of the base 1, the inner plate 302 is located inside the frame plate 301, and the array-distributed inclined plates 303 are welded between the frame plate 301 and the inner plate 302, and the main shaft 4 is rotatably connected to the outer wall of the inner plate 302, and an inclined groove 23 is opened through the outer wall of the top of the inclined plate 303, and a horizontal groove 24 is opened at both ends of the bottom outer wall of the splint 7, and the limit column 8 is slidably connected to the inner walls of the inclined groove 23 and the horizontal groove 24, and the inner wall of one side of the compensation splint 9 is fixedly connected to a guide rod 25, and the outer walls of both ends of the splint 7 are fixedly connected to linear bearings, and the guide rod 25 is slidably connected to the inner wall of the linear bearing, wherein the guide rod 25 is arranged parallel to the top of the horizontal groove 24.

[0040] Through the above solution, after the middle groove is placed between the two clamping plates 7, high-pressure gas is injected through the first air inlet pipe 11. The high-pressure gas pushes the traction rod 1002, so that the traction rod 1002 in the gas distribution mechanism 10 drives the traction block 1001 to move, thereby controlling the two clamping plates 7 to approach along the slide rail 26 and clamp the two sides of the middle groove. Because the limit column 8 is slidably connected to the inclined groove 23 of the inclined plate 303 and the transverse groove 24 of the clamping plate 7, when the clamping plate 7 moves, the limit column 8 will slide in the inclined groove 23 and the transverse groove 24, driving the compensation clamping plate 9 to move synchronously through the sliding cooperation between the guide rod 25 and the linear bearing, thereby clamping the two sides of the middle groove and ensuring that the middle groove is stable and does not move during the welding process.

[0041] In this embodiment, the mechanical linkage structure composed of the base 1, welding turning frame 2, welding table 3, main shaft 4, connecting plate 5, connecting rod 6, clamping plate 7, limiting column 8, compensation clamping plate 9 and other components drives the connecting plate 5 and the connecting rod 6 to move through the rotation of the main shaft 4, so that the clamping plate 7 moves along the slide rail 26, cooperates with the sliding of the limiting column 8 in the inclined slide groove 23 and the horizontal slide groove 24, and the sliding cooperation of the compensation clamping plate 9 with the linear bearing through the guide rod 25, to realize the "two sides + two sides" four-way synchronous clamping of the middle groove, replacing the cumbersome operation of multiple traditional independent clamps, and improving the clamping efficiency and stability.

[0042] In the second embodiment, an air distribution mechanism 10 is provided between the pair of splints 7 and the welding table 3, and the air distribution mechanism 10 includes a traction block 1001, a traction rod 1002, a ventilator 1003, a traction sleeve 1004, a spring 1005 and an air plug 1006, wherein the traction block 1001 is welded to the outer wall of the bottom of one of the pair of splints 7, the traction block 1001 is welded to the outer wall of the traction rod 1002, the outer wall of one end of the traction rod 1002 is slidably connected to the inner wall of the ventilator 1003, the outer wall of the other end of the traction rod 1002 is slidably connected to the inner wall of the traction sleeve 1004, and the spring 1005 is connected to the inner wall of the traction sleeve 1004. 005 is fixedly connected between the traction sleeve 1004 and the traction rod 1002, and the air blocking head 1006 is arranged on the outer wall of the traction rod 1002. The traction block 1001 is located between the ventilation cylinder 1003 and the traction sleeve 1004, and the ventilation cylinder 1003 and the traction sleeve 1004 are respectively fixedly connected to the top outer walls of the frame plate 301 and the inner plate 302 by screws, wherein the first air inlet pipe 11 is fixedly connected to the outer wall of one side of the ventilation cylinder 1003, the air distribution pipe 12 is fixedly connected to the top outer wall of the ventilation cylinder 1003, and the air blocking head 1006 is located on one side of the bottom outer wall of the air distribution pipe 12.

[0043] Through the above solution, when high-pressure gas is filled into the first air inlet pipe 11, the gas enters the vent tube 1003, pushing the traction rod 1002 to slide within the vent tube 1003 and the traction sleeve 1004. The traction rod 1002 drives the traction block 1001 to move, controlling the clamping of the middle groove by the clamping plate 7. When the clamping plate 7 is in place, the gas blocking head 1006 on the traction rod 1002 moves to the bottom side of the gas distribution pipe 12, opening the passage of the gas distribution pipe 12. The connection angle between the smoke pipe 14 and the oblique flushing pipe 13 is designed to be an acute angle. Some gas enters the oblique flushing pipe 13 from the gas distribution pipe 12 and rushes obliquely into the smoke pipe 14 at high speed (the angle between the oblique flushing pipe and the smoke pipe is 45 degrees). According to Bernoulli's principle in fluid mechanics, the pressure decreases as the gas flow rate increases. When the high-speed airflow enters the smoke pipe 14, a localized low-pressure zone forms within the pipe. At this point, the air pressure at the entrance of the smoke hood 15 is higher than the air pressure inside the smoke pipe 14, creating a negative pressure adsorption effect that draws welding fumes into the smoke hood 15. Due to the sudden change in direction and the change in pipe diameter, most of the airflow flows axially along the smoke pipe 14, rather than flowing out of the smoke hood 15 in the opposite direction. After the high-pressure gas flow ceases, spring 1005 forces traction rod 1002 to return to its original position, sealing head 1006 closes the passageway of the gas distribution pipe 12, and the central slot of clamping plate 7 is released.

[0044] In this embodiment, when the clamp 7 is clamped in place, the air blocking head 1006 on the traction rod 1002 opens the air distribution pipe 12 channel, realizes the air path switching, provides power for the smoke exhaust system, helps to integrate the clamping structure and the smoking structure into one, and effectively solves the cumbersome operation problem caused by the scattered fixation and independent smoke exhaust of multiple clamps in traditional technology.

[0045] The outer wall of one end of the smoke extraction hood 15 is fixedly connected to the first smoke extraction hood 16, and the outer wall of one side of the smoke extraction hood 15 is installed with a smoke extraction hood 15 distributed in an array. The outer wall of one end of the smoke extraction hood 15 is fixedly connected to the first smoke extraction hood 16. The outer walls of both sides of the welding table 3 are welded with end pipes 17, and the end pipes 17 are arranged on the inner walls of both sides of the welding turning frame 2. The outer walls of one end of the two end pipes 17 are rotatably connected to the first air intake duct 11 and the first smoke extraction duct 16 respectively through sealed bearings, and the outer wall of the other end of the end pipe 17 connected to the first air intake duct 11 is rotatably connected to the second air intake duct 19 through a sealed bearing, and the outer wall of the other end of the end pipe 17 connected to the first smoke extraction duct 16 is rotatably connected to the second smoke extraction duct 18 through a sealed bearing.

[0046] A large gear 20 is installed on the outer wall of one of the end tubes 17, and a small gear 21 is engaged with the bottom outer wall of the large gear 20. A servo motor 22 is installed on the outer wall of one side of the small gear 21, and the servo motor 22 is connected to the outer wall of one side of the welding flip frame 2 by screws.

[0047] With the above solution, when the welding table 3 needs to be flipped, the servo motor 22 is activated, which drives the pinion 21 to rotate. The pinion 21 engages the large gear 20 to rotate, which in turn drives the end pipe 17 to rotate, thereby flipping the welding table 3. Because the first and second air inlet pipes 11 and 19, as well as the first and second smoke exhaust pipes 16 and 18, are rotatably connected to the ends of the two end pipes 17 via sealed bearings, the first and second air inlet pipes 11 and 19, as well as the first and second smoke exhaust pipes 16 and 18, do not interfere with each other during rotation. Therefore, when the welding table 3 is flipped, gas delivery and smoke exhaust are not affected.

[0048] In this embodiment, the first air inlet pipe 11, the air distribution pipe 12, the oblique flushing pipe 13, the smoke pipe 14, the smoke hood 15, the first smoke exhaust pipe 16, the end pipe 17, the second smoke exhaust pipe 18 and other components constitute a smoke exhaust system. When the high-pressure gas rushes into the smoke pipe 14 through the oblique flushing pipe 13, the negative pressure effect generated by the high-speed flow of the gas is used to enable the smoke hood 15 to form an adsorption force on the welding smoke, and the smoke is discharged through the first smoke exhaust pipe 16 and the second smoke exhaust pipe 18. This design does not affect the flipping of the welding table 3, and does not require an additional independent smoke exhaust device. The smoke exhaust function is integrated into the clamping system gas path, which simplifies the equipment structure and avoids the spatial interference problem between traditional smoke exhaust components and fixtures.

[0049] A support frame 27 is welded to the top outer wall of the welding platform 3 , and the smoking pipe 14 is installed on the top inner wall of the support frame 27 . The smoking cover 15 is located on one side of the top of the middle groove.

[0050] Through the above solution, the support frame 27 fixes the smoking pipe 14, ensures that the smoking cover 15 is aligned with the welding position, and absorbs smoke and dust in time.

[0051] The top outer wall of the base 1 is located on one side of the welding flip frame 2 and is welded with a welding frame 28, and the top outer wall of the welding frame 28 is fixedly connected to the first electric guide rail 29 by screws, the slider of the first electric guide rail 29 is fixedly connected to the second electric guide rail 30, and the slider of the second electric guide rail 30 is fixedly connected to the slide 31, the outer wall of one side of the slide 31 is fixedly connected to the third electric guide rail 32 through the slider, and the bottom outer wall of the third electric guide rail 32 is installed with a laser welding head 33, and the laser welding head 33 is located on the other side of the top of the middle groove.

[0052] Through the above solution, the first electric guide rail 29, the second electric guide rail 30, the slide 31 and the third electric guide rail 32 on the welding frame 28 are used to control the movement of the laser welding head 33 in three-dimensional space to accurately weld different parts of the middle groove.

[0053] Working principle: First, place the middle groove between the two clamping plates 7, and then fill it with high-pressure gas through the first air inlet pipe 11. After the high-pressure gas enters the vent cylinder 1003, it pushes the traction rod 1002 to slide in the vent cylinder 1003 and the traction sleeve 1004, and the traction rod 1002 drives the traction block 1001 to move. Since the two clamping plates 7 are connected by the main shaft 4, the connecting plate 5 and the connecting rod 6, when one of the clamping plates 7 moves, the two connecting rods 6 will rotate a certain angle accordingly, thereby controlling the two clamping plates 7 to align and approach on the slide rail 26, clamping both sides of the middle groove, and at the same time, the compensating clamp 9 will move with the clamping plates 7, synchronously clamping both sides of the middle groove, and realizing stable fixation of the middle groove.

[0054] When the splint 7 is in place, the gas blocking head 1006 on the traction rod 1002 moves to one side of the bottom outer wall of the gas distribution pipe 12, opening the channel of the gas distribution pipe 12, and a part of the gas enters the inclined flushing pipe 13 from the gas distribution pipe 12, and then rushes into the smoking pipe 14, forming a negative pressure in the smoking pipe 14, so that the smoking hood 15 can absorb the smoke generated during the welding process, and the smoke is discharged through the first smoke exhaust pipe 16 and the second smoke exhaust pipe 18.

[0055] At the same time, the first electric guide rail 29, the second electric guide rail 30, the slide 31, and the third electric guide rail 32 on the welding frame 28 are activated, controlling the laser welding head 33 to move to the welding position and weld the middle groove. During the welding process, if different parts of the middle groove need to be welded, the servo motor 22 is activated, which drives the small gear 21 to rotate. The small gear 21 engages the large gear 20 to rotate, thereby driving the end tube 17 to rotate. The end tube 17 drives the welding table 3 to flip, realizing the flipping of the middle groove to facilitate welding different parts.

[0056] After welding is completed, stop filling with high-pressure gas. Under the action of spring 1005, the traction rod 1002 is reset, the gas blocking head 1006 closes the channel of the gas distribution pipe 12, and the middle groove of the splint 7 is loosened. The welded middle groove can be removed later to complete the entire welding process.

[0057] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
