[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Please see Figure 1-8 One embodiment of the present invention is: a partition welding machine for processing automotive parts, including a welding table 1, and further comprising:

[0062] Two slide rails 2 are symmetrically connected to the top of the welding table 1;

[0063] Two slide blocks 3 are slidably connected above the slide rail 2;

[0064] The oil tank 7 is positioned above the welding table 1 and is held by two clamping mechanisms 4; the partition 8 is positioned inside the oil tank 7.

[0065] The clamping mechanism 4 is mounted on the slide 3 and is used to clamp the oil tank 7 from the inside.

[0066] Welding torch 9, located inside oil tank 7, is used for welding partition 8 and oil tank 7;

[0067] The movable mechanism 5 is mounted on the clamping mechanism 4, and the welding torch 9 is mounted on the movable mechanism 5 for moving the welding torch 9 to weld the connection between the partition plate 8 and the oil tank 7.

[0068] Roller pressing mechanism 6, mounted on movable mechanism 5, is used to roll and press the weld slag at the weld joint;

[0069] The clamping mechanism 4 includes:

[0070] Multiple arc-shaped clamps 41 are respectively installed on the inner wall of the oil tank 7, and the outer wall of the arc-shaped clamps 41 is used to fit against the outer wall of the oil tank 7 and clamp it.

[0071] An adjustment component is mounted on the slide block 3 and connected to each arc-shaped clamp 41 for pushing the arc-shaped clamp 41 to move.

[0072] The adjustment components include:

[0073] The fixed sleeve 42 is fixedly connected to one side of the slide 3. The inner wall of the fixed sleeve 42 is rotatably connected to a rotating shaft, and one end of the rotating shaft moves through the slide 3.

[0074] Motor 43 is mounted on the other side of slide 3, and the output end of motor 43 is connected to the through end of the rotating shaft to drive the rotating shaft to rotate.

[0075] The gearbox 44 is fixedly connected to the fixed sleeve 42 on the side away from the slide 3, and the other end of the rotating shaft extends movably into the gearbox 44;

[0076] A bidirectional threaded rod 45 is mounted on a gearbox 44, and a gear is mounted in its middle and located inside the gearbox 44. The rotating shaft drives the bidirectional threaded rod 45 to rotate through the gear inside the gearbox 44.

[0077] Two limiting rods 46 are fixedly connected to the outer wall of the gearbox 44 respectively;

[0078] Two movable blocks 47 are threadedly connected to the outer wall of the bidirectional threaded rod 45 and slidably connected to the limiting rod 46;

[0079] Multiple connecting rods 48 are respectively hinged to the top and bottom of the movable block 47, and the other side is hinged to the arc-shaped clamping block 41.

[0080] The arc-shaped clamping block 41 is provided with staggered rectangular grooves, and each arc-shaped clamping block 41 fits into each other through the rectangular grooves and fits into the inner wall of the oil tank 7.

[0081] The two upper arc-shaped clamping blocks 41 and the two lower arc-shaped clamping blocks 41 contract and open with each other through rectangular grooves;

[0082] The two arc-shaped clamping blocks 41 on the front and the two arc-shaped clamping blocks 41 on the back contract and open with each other through rectangular grooves.

[0083] Working principle: When welding the partition 8 in the oil tank 7, the oil tank 7 is first placed on the welding table 1. Then, by moving the two sliding blocks 3, the clamping mechanisms 4 on both sides are moved into the oil tank 7. After the clamping mechanisms 4 are moved into the oil tank 7, the fixing rods 51 will approach each other and abut against the partition 8, achieving initial clamping of the partition 8. At this time, the motors 43 on the clamping mechanisms 4 on both sides are started. The motors 43 drive the rotating shaft to rotate. The rotating shaft drives the bidirectional threaded rod 45 to rotate through the gear transmission inside the gearbox 44. Due to the limiting action of the limiting rod 46 on the movable block 47, the rotation of the bidirectional threaded rod 45 will push the two movable blocks 47 to move forward and backward on the bidirectional threaded rod 45 and the limiting rod 46, respectively. When the movable block 47 moves away from the gearbox 44, it will push the hinged connecting rod 48 on it to move, thereby pushing the arc-shaped clamping blocks 41 on the front and rear sides away from each other and gradually approaching the inner wall of the oil tank 7, achieving front and rear clamping of the oil tank 7.

[0084] As the movable block 47 continues to move, it continues to push the connecting rod 48. Because the two ends of the hinged rod 48 are hinged, it pushes the upper and lower arc-shaped clamping blocks 41 to slide against the inner wall of the oil tank 7 and fit against the upper and lower sides of the inner wall of the oil tank 7. Finally, when the movable block 47 stops moving, the four arc-shaped clamping blocks 41 fit against the upper, lower, front, and rear inner walls of the oil tank 7 respectively, thereby achieving stable clamping of the oil tank 7, effectively preventing the oil tank 7 from moving during welding and improving the stability of welding.

[0085] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, the active mechanism 5 includes:

[0086] The fixing rod 51 is fixedly connected to the side of the gearbox 44 away from the fixing sleeve 42;

[0087] The toothed ring 53 is connected to the fixed rod 51 via multiple connecting rods 52;

[0088] The movable groove 54 is formed on the inner ring of the toothed ring 53;

[0089] A movable component, mounted on the movable slot 54, is used to drive the welding torch 9 to move along the movable slot 54.

[0090] The mobile components include:

[0091] The motor housing 55 is located inside the gear ring 53;

[0092] The fixing block 57 is fixedly connected to the outer wall of the motor housing 55, and the bottom of the fixing block 57 is connected to the inner wall of the movable groove 54 through two ball connecting rods 58;

[0093] A servo motor is installed on the inner wall of the motor housing 55, and the output end of the servo motor moves through the motor housing 55 and extends downward. A spur gear 56 is fixedly sleeved on the outer wall of the output end of the servo motor, and the spur gear 56 meshes with the tooth groove of the tooth ring 53.

[0094] Telescopic rod 59 is fixedly connected to the bottom of motor box 55, and welding gun 9 is installed on the outer wall of telescopic rod 59. The tip of welding gun 9 is tilted and aligned with the angle between the partition plate 8 and the inner wall of oil tank 7.

[0095] The conduit 10 is connected to the welding torch 9 and extends from the bottom of the gearbox 44 to the outside of the oil tank 7.

[0096] The bottom of the telescopic rod 59 is hinged with a roller 592, and the outer wall of the roller 592 is attached to the inner wall of the oil tank 7.

[0097] The outer wall of the telescopic rod 59 is fitted with a roller 591, and the outer wall of the roller 591 is in contact with the inner wall of the arc-shaped clamp 41.

[0098] Working principle: After the oil tank 7 and the partition 8 are clamped and fixed, the servo motor is started. The output end of the servo motor drives the spur gear 56 to rotate. Since the spur gear 56 meshes with the gear ring 53, and the gear ring 53 is fixedly connected to the fixed rod 51 through the connecting rod 52, the rotation of the spur gear 56 will push it to move on the gear ring 53, thereby driving the motor housing 55 to move. The motor housing 55 slides on the movable groove 54 through the fixed block 57 and the ball connecting rod 58, thereby driving the welding torch 9 to move, realizing the welding at the connection between the oil tank 7 and the partition 8.

[0099] Meanwhile, by utilizing the telescopic rod 59, the welding torch 9 installed at its output end can always maintain a fixed distance from the welding point, ensuring the stability of the welding process and avoiding the welding effect being affected by changes in the height of the welding torch.

[0100] In addition, the roller 592 at the bottom of the telescopic rod 59 is attached to the inner wall of the oil tank 7, which, together with the telescopic rod 59, pushes the welding torch 9 to maintain a fixed position and move it within the inner wall of the oil tank 7, further improving the stability during welding. Meanwhile, the roller 591 on the outer wall of the telescopic rod 59 is attached to the inner wall of the arc-shaped clamp 41, which facilitates the recovery and adjustment of the position of the welding torch 9 during the welding process, ensuring the flexibility and precision of the welding operation.

[0101] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, the roller pressing mechanism 6 includes:

[0102] The arc-shaped telescopic rod 61 is fixedly connected to the outer wall of the telescopic rod 59;

[0103] Friction roller 62 is rotatably connected to the telescopic end of arc-shaped telescopic rod 61, and the outer wall of friction roller 62 is in rolling contact with the weld slag after welding.

[0104] The roller pressing mechanism 6 also includes:

[0105] The lever 63 is fixedly connected to the outer wall of the telescopic end of the arc-shaped telescopic rod 61;

[0106] Multiple spherical protrusions 64 are fixedly connected to the side wall of the arc-shaped clamp 41, and the outer wall of the spherical protrusions 64 is in contact with the lever 63.

[0107] Working Principle: When the welding torch 9 moves under the drive of the movable mechanism 5 for welding, the arc-shaped telescopic rod 61 pushes the friction roller 62 to contact the weld slag. As the welding torch 9 moves, the friction roller 62 rolls on the weld slag and generates pressure, thereby achieving the purpose of removing the weld slag. At the same time, during the movement of the welding torch 9, the lever 63 located on the outer wall of the arc-shaped telescopic rod 61 will abut against the spherical protrusion 64. Due to the unevenness of the spherical protrusion 64, when the lever 63 contacts the spherical protrusion 64, it will be squeezed and push the telescopic rod of the arc-shaped telescopic rod 61 to move. When the lever 63 disengages from the spherical protrusion 64, the telescopic rod of the arc-shaped telescopic rod 61 will return to its original position. Through this continuous process of movement and contact, the force exerted by the friction roller 62 when contacting the weld slag is changed, causing uneven stress on the weld slag, thereby promoting the removal of the weld slag from the weld joint. Removing the weld slag not only reduces stress concentration but also avoids corrosion of the weld joint caused by oxides and impurities in the weld slag, especially in humid or corrosive environments. Therefore, the setting of the roller pressing mechanism 6 is of great significance for improving the strength and durability of the welded joint.

Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention.
