Description

Technical Field

[0001] This invention relates to the field of oil pipe joint welding technology, and in particular to a welding mechanism for assembling automotive oil pipe joints. Background Technology

[0002] Automotive oil pipe fittings are components used to connect oil pipes and play a crucial role in hydraulic systems and oil transmission. Their main function is to ensure a secure and reliable connection between oil pipes, prevent oil leakage, and guarantee the normal operation of the oil circuit.

[0003] The welding mechanism for automotive oil pipe joints refers to the tools and equipment specifically used for welding automotive oil pipe joints. It mainly uses welding to ensure a firm and reliable connection between the oil pipe and the oil pipe joint, prevent oil leakage, and ensure the normal operation of the oil circuit system.

[0004] Existing oil pipe joint welding mechanisms mainly rely on threaded fixing during welding, resulting in low efficiency for changing joints of different specifications. Frequent mold changes are required, affecting production efficiency. Furthermore, the welding process lacks treatment of harmful gases, polluting the working environment and endangering workers' health. In addition, while the existing single welding gun surround welding process is fast, it is prone to problems such as insufficient local strength and poor airtightness of the weld, resulting in low quality oil pipe joints. Therefore, this application provides a welding mechanism for assembling automotive oil pipe joints to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a welding mechanism for assembling automotive oil pipe joints to solve the problems caused by the existing reliance on threaded fixing methods, which leads to difficulties in switching between multiple specifications, frequent mold changes that significantly reduce production efficiency, the lack of a harmful gas collection and treatment system in the welding process, direct emission that endangers workers' health, and the fact that although single welding gun circumferential welding has a relatively fast welding speed, it is prone to process quality problems such as uneven weld strength and airtightness defects.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A welding mechanism for assembling automotive oil pipe joints includes a body, a bracket mounted on the top of the body, a lifting bracket slidably connected to the end of the bracket, a servo motor mounted on the top of the lifting bracket, a hydraulic cylinder mounted on the top of the bracket, an operating table on the surface of the body, a joint mounted on the top of the operating table, and an oil pipe mounted below the lifting bracket. A welding fumigation assembly is mounted on the top of the operating table for fixing the joint and absorbing fumes. An oil pipe clamping assembly is mounted at the bottom of the lifting bracket for clamping oil pipes of different sizes. An oil pipe welding assembly is mounted at the output end of the servo motor for welding the connection between the oil pipe and the joint. The oil pipe clamping assembly is positioned above the welding fumigation assembly, and the oil pipe welding assembly is mounted at the bottom of the oil pipe clamping assembly.

[0007] Optionally, the welding fume extraction assembly includes a fume collection box, which is installed on one side of the machine body. A conduit is installed at the end of the fume collection box, and a perforated working pipe is installed at one end of the conduit. Two sets of annular guide pipes are installed on the inner wall of the perforated working pipe, and the two sets of annular guide pipes are arranged at the top and bottom of the perforated working pipe.

[0008] Optionally, the end of the annular guide pipe is equipped with multiple smoking heads, the top of the operating table is equipped with a circular base, the circular base is disposed inside the perforated working pipe, and the top of the circular base is equipped with a sliding frame.

[0009] Optionally, a threaded rod knob is rotatably connected to the top of the slide rail frame, a threaded tube is threadedly connected to the surface of the threaded rod knob, a connecting plate is rotatably connected to the end of the threaded tube, a sliding plate is rotatably connected to one end of the connecting plate, the end of the sliding plate is slidably connected to the slide rail frame, and an arc-shaped top plate is installed at one end of the sliding plate.

[0010] Optionally, the tubing clamping assembly includes a mounting block, which is mounted on one end of the tubing welding assembly. A threaded rotating rod is inserted into the top of the mounting block, a first gear is mounted on the surface of the threaded rotating rod, a bolt is threaded to the bottom of the threaded rotating rod, and a transmission gear is meshed with the end of the first gear.

[0011] Optionally, one end of the transmission gear is meshed with a second gear, the top of the second gear is rotatably connected to a connecting frame, the other end of the connecting frame is mounted on the top of the first gear, the bottom of the second gear is rotatably connected to a hollow turntable, one end of the second gear is meshed with a toothed turntable, the toothed turntable and the hollow turntable are rotatably connected, and a first connecting shaft is inserted into the surface of the toothed turntable.

[0012] Optionally, a second connecting shaft is inserted into the end surface of the hollow turntable, a rotating plate is rotatably connected to the end of the first connecting shaft, a connecting arm plate is rotatably connected to one end of the rotating plate, one end of the connecting arm plate is rotatably connected to the second connecting shaft, and a clamping post is installed at one end of the rotating plate.

[0013] Optionally, the oil pipe welding assembly includes a rotating disk, which is installed at the output end of a servo motor. A first connecting rod is rotatably connected to the bottom of one end of the rotating disk. A driving plate is rotatably connected to the bottom of the first connecting rod. A second connecting rod is rotatably connected to one end of the driving plate. A mounting plate is rotatably connected to the bottom of the second connecting rod.

[0014] Optionally, a rotating cylinder is installed at one end of the mounting plate, and a rotating sleeve shaft is rotatably connected to the surface of the rotating cylinder. The rotating sleeve shaft is installed at the upper and lower ends of the lifting bracket. A welding frame is installed at the bottom of the rotating cylinder, and multiple mounting boxes are installed at the ends of the welding frame. A support rod is installed at one end of each mounting box.

[0015] Optionally, an arc-shaped plate is installed at the end of the support rod, a cylinder is installed at one end of the arc-shaped plate, a telescopic rod is installed at the other end of the arc-shaped plate, a welding gun is installed at the output end of the cylinder, and one end of the welding gun is connected to the end of the telescopic rod.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a welding fume extraction assembly, the rotation of a threaded rod knob drives the opening and closing of multiple arc-shaped top plates, allowing for stepless adjustment of the diameter formed by the multiple sets of arc-shaped top plates. This adapts to a wider range of oil pipe joint specifications, enhancing the adaptability of the welding mechanism, shortening the time spent changing molds of different sizes, and improving production efficiency. Simultaneously, the integrated negative pressure fume extraction device, in conjunction with a filter fume box, captures welding fumes, reducing the concentration of fumes in the working area, protecting worker health, and preventing the welding process from affecting the weld joint. Furthermore, the negative pressure airflow generated by the fume collection box during welding accelerates the welding cooling time and the forming time, further improving production efficiency. By setting up a tubing clamping assembly, a flexible clamping capability is achieved. The gear transmission system drives multiple sets of clamping columns to move radially synchronously, reducing the size of their surrounding area. This allows for quick adaptation to clamp tubing of different diameters, reducing the time required for traditional clamp replacements. While clamping quickly, it also enables the clamping of tubing of different sizes and specifications. Simultaneously, the synchronous drive between the turntable and the connecting shaft achieves the positioning and lifting of the tubing, reducing clamping errors and avoiding issues such as weld misalignment that could lead to airtightness defects.

[0017] By setting up an oil pipe welding assembly, a servo motor drives a rotating disk to rotate, causing the rotating cylinder to reciprocate. This allows the welding gun to weld evenly along the circumference of the oil pipe joint, reducing downtime and repositioning time during the welding process and improving welding efficiency. Simultaneously, multiple welding guns welding from different angles ensure more uniform heating of the weld, reducing welding deformation and stress concentration caused by localized overheating or uneven cooling, thus improving weld quality. Furthermore, the rotary reciprocating welding produces a smoother, more uniform weld, reducing defects such as porosity and slag inclusions, improving weld density and strength, and achieving a higher weld overlap rate. Compared to traditional single-point welding, this reduces porosity, increases tensile strength at the weld, improves weld quality, and prevents localized areas of insufficient strength in the weld.

[0027] like Figures 1 to 13 As shown, an embodiment of the present invention provides a welding mechanism for assembling automotive oil pipe joints, including a body 1, a bracket 2 mounted on the top of the body 1, a lifting bracket 3 slidably connected to the end of the bracket 2, a servo motor 4 mounted on the top of the lifting bracket 3, a hydraulic cylinder 5 mounted on the top of the bracket 2, an operating table 9 provided on the surface of the body 1, a joint 10 provided on the top of the operating table 9, and an oil pipe 11 provided below the lifting bracket 3; a welding fumigation assembly 6 is mounted on the top of the operating table 9, which is used to fix the joint 10 and absorb fumes; an oil pipe clamping assembly 7 is mounted on the bottom of the lifting bracket 3, which is used to clamp oil pipes 11 of different sizes; an oil pipe welding assembly 8 is mounted on the output end of the servo motor 4, which is used to weld the connection between the oil pipe 11 and the joint 10; the oil pipe clamping assembly 7 is provided above the welding fumigation assembly 6, and the oil pipe welding assembly 8 is mounted on the bottom of the oil pipe clamping assembly 7.

[0028] As an implementation method in this embodiment, such as Figures 3 to 6As shown, the welding fume extraction assembly 6 includes a fume collection box 61, which is installed on one side of the machine body 1. A conduit 62 is installed at one end of the fume collection box 61, and a perforated working pipe 63 is installed at one end of the conduit 62. Two sets of annular guide pipes 64 are installed on the inner wall of the perforated working pipe 63, located at the top and bottom of the perforated working pipe 63. Multiple fume extraction heads 65 are installed at the ends of the annular guide pipes 64. A circular base 66 is installed on the top of the operating platform 9, located inside the perforated working pipe 63. A chute frame 67 is installed on the top of the circular base 66. A threaded rod knob 68 is rotatably connected to the top of 67. A threaded tube 69 is threadedly connected to the surface of the threaded rod knob 68. A connecting plate 610 is rotatably connected to the end of the threaded tube 69. A sliding plate 612 is rotatably connected to one end of the connecting plate 610. The end of the sliding plate 612 is slidably connected to the slide rail frame 67. An arc-shaped top plate 611 is installed at one end of the sliding plate 612. When the connector 10 is placed inside the perforated working tube 63 and then placed on top of the threaded tube 69, the top of the arc-shaped top plate 611 around the threaded tube 69 supports it on the inner wall of the connector 10. Then, by rotating the threaded rod knob 68, when the threaded tube 69 is in the working tube 63, the threaded tube 69 is rotatably connected to the top of the slide rail frame 67. When the lever knob 68 begins to rotate, the threaded tube 69, threaded to the surface of the threaded lever knob 68, begins to move downwards. During the movement of the threaded tube 69, the threaded lever knob 68 simultaneously rotates at the center of the slide rail frame 67. As the threaded tube 69 moves, it drives the connecting plate 610 to move as well. However, due to the action of the sliding plate 612, which is rotatably connected to the other end of the connecting plate 610, the connecting plate 610 begins to flip, while the sliding plate 612 slides within the slide rail frame 67 on top of the circular base 66. At this time, multiple sets of sliding plates 612 move around the threaded tube 69. During this movement... The sliding plate 612 drives the arc-shaped top plate 611 installed at one end to move together. Then, the moving arc-shaped top plate 611 gradually presses against the inner wall of the joint 10, and then the installation is fixed. Then, when the joint 10 is welded to the oil pipe 11, the dust collection box 61 starts to drive. The dust collection box 61 generates negative pressure wind force, which acts on the duct 62. Then, the duct 62 draws air into the annular guide pipe 64. Then, the annular guide pipe 64 uses the suction force through the smoke head 65 to capture and absorb the dust generated in the perforated working pipe 63. Then, the dust is filtered by the dust collection box 61 and discharged outside the device.

[0029] As an implementation method in this embodiment, such as Figures 7 to 11As shown, the tubing clamping assembly 7 includes a mounting block 71, which is mounted on one end of the tubing welding assembly 8. A threaded rotating rod 72 is inserted into the top of the mounting block 71. A first gear 74 is mounted on the surface of the threaded rotating rod 72, and a bolt 73 is threadedly connected to the bottom of the threaded rotating rod 72. A transmission gear 75 is meshed with the end of the first gear 74, and a second gear 76 is meshed with one end of the transmission gear 75. A connecting bracket 77 is rotatably connected to the top of the second gear 76, and the other end of the connecting bracket 77 is mounted on the top of the first gear 74. The bottom of the second gear 76... A hollow turntable 78 is rotatably connected to the first gear 78. One end of the second gear 76 is meshed with a toothed turntable 79, which is rotatably connected to the hollow turntable 78. A first connecting shaft 710 is inserted into the surface of the toothed turntable 79, and a second connecting shaft 711 is inserted into the end surface of the hollow turntable 78. A rotating plate 712 is rotatably connected to the end of the first connecting shaft 710. A connecting arm plate 713 is rotatably connected to one end of the rotating plate 712, and one end of the connecting arm plate 713 is rotatably connected to the second connecting shaft 711. A clamping post 714 is mounted on one end of the rotating plate 712. When the oil pipe 11 is placed into the rotating cylinder 86, and then the oil pipe 11 moves to the output end of the welding torch 813, the threaded rotating rod 72 on the mounting block 71 begins to rotate. Subsequently, the threaded rotating rod 72 drives the first gear 74 to rotate. The rotation of the first gear 74 causes the transmission gear 75 and the second gear 76, which are meshed and connected at the bottom of the connecting frame 77, to rotate successively. At this time, the toothed turntable 79 is rotated synchronously by the rotation of the second gear 76. When the toothed turntable 79 rotates, the first connecting shaft 710 mounted on the toothed turntable 79 rotates synchronously. The first connecting shaft 710 moves, causing the rotating plate 712, which is rotatably connected at one end, to move. At this time, the second connecting shaft 711 is fixed on the hollow turntable 78. The connecting arm plate 713 is rotated around the axis of the second connecting shaft 711 due to the rotation of the rotating plate 712. At this time, the rotating plate 712 flips around the first connecting shaft 710. Then, multiple sets of clamping columns 714 begin to flip inward to clamp the oil pipe 11. After the clamping and fixing are completed, the bolts 73 at the bottom of the rotating mounting block 71 fix the threaded rotating rod 72.

[0030] As an implementation method in this embodiment, such as Figures 8 to 13As shown, the oil pipe welding assembly 8 includes a rotating disk 81, which is mounted on the output end of the servo motor 4. A first connecting rod 82 is rotatably connected to the bottom of one end of the rotating disk 81. A driving plate 83 is rotatably connected to the bottom of the first connecting rod 82. A second connecting rod 84 is rotatably connected to one end of the driving plate 83. A mounting plate 85 is rotatably connected to the bottom of the second connecting rod 84. A rotating cylinder 86 is mounted on one end of the mounting plate 85. A rotating sleeve shaft 87 is rotatably connected to the surface of the rotating cylinder 86. The rotating sleeve shaft 87 is mounted on the upper and lower ends of the lifting bracket 3. A welding frame 88 is mounted on the bottom of the rotating cylinder 86. Multiple mounting boxes 89 are mounted on the ends of the welding frame 88. A support rod 810 is mounted on one end of each mounting box 89. An arc-shaped... Plate 811, with a cylinder 812 mounted at one end and a telescopic rod 814 mounted at the other end. A welding torch 813 is mounted at the output end of the cylinder 812, with one end of the torch 813 connected to the end of the telescopic rod 814. When the oil pipe 11 is clamped, the oil pipe welding assembly 8 begins operation. At this time, the servo motor 4 starts, and the rotating disk 81 begins to rotate under the drive of the servo motor 4. When the rotating disk 81 rotates, the first connecting rod 82, rotatably connected to the bottom of one end of the rotating disk 81, rotates around the axis of the rotating disk 81. When the first connecting rod 82 rotates, the driving plate 83, rotatably connected to the bottom of the first connecting rod 82, rotates along with it. Subsequently, the other end of the driving plate 83 drives the mounting plate 84, which is mounted at the bottom of the second connecting rod 84. The plate 85 rotates together with the rotating cylinder 86, which in turn rotates within the rotating sleeve shaft 87. The rotating cylinder 86, mounted on the end of the mounting plate 85, begins to reciprocate within the rotating sleeve shaft 87 of the lifting bracket 3. As the rotating cylinder 86 rotates, it drives the welded frame 88 mounted at the bottom to rotate as well. Since the pipes of the oil pipe clamping assembly 7 within the rotating sleeve shaft 87 are connected to the end of the rotating sleeve shaft 87 and fixedly installed within the lifting bracket 3, the oil pipe clamping assembly 7 remains stationary while the rotating cylinder 86 reciprocates under the drive of the servo motor 4. Simultaneously, the rotation of the welded frame 88 drives multiple sets of mounting boxes 89... As the mounting boxes 89 rotate, the arc-shaped plate 811 installed at one end of the support rod 810 rotates along with the mounting box 89. At this time, the rotation of the arc-shaped plate 811 drives the cylinder 812 to rotate. Then, the output distance of the cylinder 812 is adjusted according to the position of the oil pipe, so that the welding torch 813 installed at the output end of the cylinder surrounds the surface of the oil pipe 11. When the welding torch 813 moves under the output of the cylinder 812, the telescopic rod 814 installed at one end of the welding torch 813 moves accordingly to ensure the stability of the welding torch. Then, the rotating welding frame 88 drives the multiple welding torches 813 to rotate circumferentially around the surface of the oil pipe 11. At this time, the multiple welding torches 813 begin to weld the connection between the oil pipe 11 and the joint 10.

[0031] The working principle of the technical solution provided by this invention is as follows: When using this device, first tidy up the operating platform 9 on top of the machine body 1 to ensure the work surface is clean. Then, adjust the height of the lifting bracket 3 of the support 2 by driving the hydraulic cylinder 5. Then prepare to install the connector 10 and oil pipe 11.

[0032] When the joint 10 is ready for installation, the welding fume extraction assembly 6 starts operating. At this time, the joint 10 is placed inside the perforated working pipe 63 and then placed on top of the threaded pipe 69. The top of the arc-shaped top plate 611 around the threaded pipe 69 supports it against the inner wall of the joint 10. Then, by rotating the threaded rod knob 68, the threaded pipe 69, threaded to the surface of the threaded rod knob 68, begins to move downwards. During the movement of the threaded pipe 69, the threaded rod knob 68 simultaneously rotates at the center of the slide rail frame 67. As the threaded pipe 69 moves, it drives the connecting plate 610 to move. However, due to the action of the sliding plate 612, which is rotatably connected to the other end of the connecting plate 610, the connecting plate 610 begins to flip, while the sliding plate... The 612 slides in the slide frame 67 on the top of the circular base 66. At this time, multiple sets of sliding plates 612 move around the threaded tube 69. The moving sliding plates 612 drive the arc-shaped top plate 611 installed at one end to move together. Then the moving arc-shaped top plate 611 gradually presses against the inner wall of the joint 10, and then the installation is fixed. Then, when the joint 10 is welded to the connection of the oil pipe 11, the dust collection box 61 starts to drive. The dust collection box 61 generates negative pressure wind force, which acts on the duct 62. Then the duct 62 draws air into the annular guide pipe 64. Then the annular guide pipe 64 uses the suction force through the smoke head 65 to capture and absorb the dust generated in the perforated working pipe 63. Then the dust is filtered by the dust collection box 61 and discharged outside the device.

[0033] After the connector 10 is installed, the tubing clamping assembly 7 begins operation. First, the tubing 11 is placed into the rotating cylinder 86. Then, when the tubing 11 moves to the output end of the welding torch 813, the threaded rotating rod 72 on the mounting block 71 begins to rotate. Subsequently, the threaded rotating rod 72 drives the first gear 74 to rotate. The rotation of the first gear 74 causes the transmission gear 75 and the second gear 76, which are meshed and connected at the bottom of the connecting frame 77, to rotate successively. At this time, the toothed turntable 79 rotates synchronously due to the rotation of the second gear 76. When the toothed turntable 79 rotates, the first connecting shaft 71 mounted on the toothed turntable 79... 0. Simultaneous movement occurs. At this time, the movement of the first connecting shaft 710 drives the rotating plate 712, which is rotatably connected at one end, to begin moving. Meanwhile, the second connecting shaft 711 is fixed on the hollow turntable 78. The connecting arm plate 713 is rotated around the axis of the second connecting shaft 711 due to the rotation of the rotating plate 712. At this time, the rotating plate 712 flips around the first connecting shaft 710. Then, multiple sets of clamping columns 714 begin to flip inward to clamp the oil pipe 11. After the clamping and fixing are completed, the bolts 73 at the bottom of the rotating mounting block 71 fix the threaded rotating rod 72. Then, the oil pipe welding assembly 8 begins to operate.

[0034] After the oil pipe 11 is clamped, the oil pipe welding assembly 8 starts operating. At this time, the servo motor 4 starts, and the rotating disk 81 starts to rotate under the drive of the output end of the servo motor 4. When the rotating disk 81 rotates, the first connecting rod 82, which is rotatably connected to the bottom of one end of the rotating disk 81, rotates around the axis of the rotating disk 81. When the first connecting rod 82 rotates, the driving plate 83, which is rotatably connected to the bottom of the first connecting rod 82, rotates together. Then, the other end of the driving plate 83 drives the mounting plate 85 installed at the bottom of the second connecting rod 84 to rotate together. At the same time, under the action of the rotating cylinder 86, the rotating cylinder 86 is acted upon by the rotating sleeve shaft 87 and only rotates within the rotating sleeve shaft 87. Then, the rotating cylinder 86 installed at the end of the mounting plate 85 begins to reciprocate within the rotating sleeve shaft 87 in the lifting bracket 3. When the rotating cylinder 86 rotates, it drives the welding frame 88 installed at the bottom to rotate together. At the same time, because the pipe of the oil pipe clamping assembly 7 in the rotating sleeve shaft 87 is connected to the end of the rotating sleeve shaft 87, the pipes of the oil pipe clamping assembly 7 rotate together with the end of the rotating sleeve shaft 87. The components are connected and fixedly installed in the lifting bracket 3. Therefore, when the rotating cylinder 86 is driven by the servo motor 4 to reciprocate, the oil pipe clamping assembly 7 remains stationary. Simultaneously, when the welding frame 88 rotates, it drives multiple mounting boxes 89 to rotate as well. As the mounting boxes 89 rotate, the arc-shaped plate 811 installed at one end of the support rod 810 rotates along with the mounting boxes 89. At this time, the rotation of the arc-shaped plate 811 drives the cylinder 812 to rotate. The output distance of the cylinder 812 is adjusted according to the position of the oil pipe, so that the welding torch 813 installed at the output end of the cylinder surrounds the surface of the oil pipe 11. When the welding torch 813 moves due to the output of the cylinder 812, the telescopic rod 814 installed at one end of the welding torch 813 moves accordingly to ensure the stability of the welding torch. Then, the rotating welding frame 88 drives multiple sets of welding torches 813 to rotate in a circle around the surface of the oil pipe 11. At this time, multiple sets of welding torches 813 begin to weld the connection between the oil pipe 11 and the joint 10.
