[0065] A clamping mechanism 4 is provided on the slide 3 and is used to clamp the oil tank 7 from the inside;

[0066] A welding gun 9 is arranged in the oil tank 7 and is used for welding the partition plate 8 and the oil tank 7;

[0067] The movable mechanism 5 is arranged on the clamping mechanism 4, and the welding gun 9 is arranged on the movable mechanism 5, and is used to move the welding gun 9 to weld the connection between the partition plate 8 and the oil tank 7;

[0068] A rolling mechanism 6, arranged on the movable mechanism 5, is used for rolling the welding slag at the welding position;

[0069] Wherein, the clamping mechanism 4 comprises:

[0070] A plurality of arc-shaped clamping blocks 41 are respectively arranged on the inner wall of the oil tank 7, and the outer wall of the arc-shaped clamping blocks 41 is used to fit the outer wall of the oil tank 7 and clamp;

[0071] The adjusting assembly is arranged on the slide seat 3 and connected to each arc-shaped clamping block 41 to push the arc-shaped clamping block 41 to move.

[0072] The adjustment components include:

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

[0074] The motor 43 is installed on the other side of the slide 3, and the output end of the motor 43 is connected to the through end of the shaft to drive the shaft to rotate;

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

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

[0077] Two limit rods 46 are respectively fixedly connected to the outer wall of the gear box 44;

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

[0079] A plurality of connecting rods 48 are respectively hinged on 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 blocks 41 are provided with staggered rectangular grooves, and each arc-shaped clamping block 41 fits with each other through the rectangular grooves and fits with the inner wall of the oil tank 7;

[0081] The upper two arc-shaped clamping blocks 41 and the lower two arc-shaped clamping blocks 41 are mutually contracted and opened through the rectangular groove;

[0082] The two arc-shaped clamping blocks 41 on the front side and the two arc-shaped clamping blocks 41 on the back side are contracted and opened with each other through the rectangular groove.

[0083] Working principle: When welding the partition 8 in the oil tank 7, first place the oil tank 7 on the welding table 1, and then move the two slides 3 to move the clamping mechanisms 4 on both sides to the inside of the oil tank 7. When the clamping mechanism 4 moves to the inside of the oil tank 7, the fixed rods 51 will approach each other and contact the partition 8 to achieve preliminary clamping of the partition 8. At this time, start the motors 43 on the clamping mechanisms 4 on both sides, and the motors 43 drive the rotating shaft to rotate. The rotating shaft drives the two-way threaded rod 45 to rotate through the gear transmission inside the gear box 44. Due to the limiting effect of the limit rod 46 on the movable block 47, the rotation of the two-way threaded rod 45 will push the two movable blocks 47 to move forward and backward on the two-way threaded rod 45 and the limit rod 46 respectively. When the movable block 47 moves away from the gear box 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, to achieve front and rear clamping of the oil tank 7;

[0084] As the movable block 47 continues to move, it will continue to push the connecting rod 48. Since the two ends of the hinged rod 48 are hinged, it will push the upper and lower arc-shaped clamping blocks 41 to slide on the inner wall of the oil tank 7 and fit to 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 to the upper and 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 during welding.

[0085] See also Figure 1-8 Based on the above embodiment, in another embodiment of the present invention, the movable mechanism 5 includes:

[0086] A fixing rod 51 is fixedly connected to a side of the gear box 44 away from the fixing sleeve 42;

[0087] The gear ring 53 is connected to the fixed rod 51 through a plurality of connecting rods 52;

[0088] The movable groove 54 is provided on the inner ring of the gear ring 53;

[0089] The moving assembly is arranged on the movable groove 54 and is used for driving the welding gun 9 to move along the movable groove 54 .

[0090] The mobile components include:

[0091] A motor box 55 is arranged inside the gear ring 53;

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

[0093] The servo motor is mounted on the inner wall of the motor box 55, and the output end of the servo motor movably penetrates the motor box 55 and extends downward, and a spur gear 56 is fixedly sleeved on the outer wall of the output end of the servo motor, and the spur gear 56 is meshed with the tooth groove of the gear ring 53;

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

[0095] The wire tube 10 is connected to the welding gun 9 and is connected to the bottom of the gear box 44 and extends to the outside of the oil tank 7 .

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

[0097] A roller 591 is installed on the outer wall of the telescopic rod 59 , and the outer wall of the roller 591 is in contact with the inner wall of the arc-shaped clamping block 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 is meshed 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 box 55 to move. The motor box 55 slides on the movable groove 54 through the fixed block 57 and the spherical connecting rod 58, thereby driving the welding gun 9 to move, and realizes the welding of the connection between the oil tank 7 and the partition 8;

[0099] At the same time, by utilizing the function of the telescopic rod 59, the welding gun 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 influence of the welding effect due to the height change of the welding gun;

[0100] In addition, roller 2 592 at the bottom of the telescopic rod 59 is attached to the inner wall of the oil tank 7, and cooperates with the telescopic rod 59 to push the welding gun 9 to maintain a fixed position and move on the inner wall of the oil tank 7, further improving the stability during welding, while roller 1 591 on the outer wall of the telescopic rod 59 is attached to the inner wall of the arc clamping block 41, which is convenient for recovering and adjusting the position of the welding gun 9 during the welding process, ensuring the flexibility and accuracy of the welding operation.

[0101] See also Figure 1-8 Based on the above embodiment, in another embodiment of the present invention, the rolling mechanism 6 includes:

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

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

[0104] The rolling 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] A plurality of spherical protrusions 64 are respectively fixedly connected to the side walls of the arc-shaped clamping block 41 , and the outer wall of the spherical protrusion 64 is in contact with the lever 63 .

[0107] Working principle: When the welding gun 9 moves to weld under the drive of the movable mechanism 5, the arc telescopic rod 61 will push the friction roller 62 to contact the welding slag after welding. As the welding gun 9 moves, the friction roller 62 rolls on the welding slag and produces extrusion, thereby achieving the purpose of removing the welding slag. At the same time, during the movement of the welding gun 9, the lever 63 located on the outer wall of the arc telescopic rod 61 will fit onto the spherical bump 64. Due to the unevenness of the spherical bump 64, when the lever 63 contacts the spherical bump 64, it will be squeezed and push the telescopic rod of the arc telescopic rod 61 to move. When the lever 63 is separated from the spherical bump 64, the telescopic rod of the arc telescopic rod 61 will reset. Through this continuous movement and contact process, the force of the friction roller 62 when contacting the welding slag is changed, so that the welding slag is unevenly stressed, thereby promoting the welding slag to separate from the welding place. Removing welding slag can not only reduce stress concentration, but also prevent oxides and impurities in the welding slag from corroding the welded joint, especially in a humid or corrosive environment. Therefore, the provision of the rolling mechanism 6 is of great significance for improving the strength and durability of the welded joint.

[0108] The present invention provides a partition welding machine for automobile parts processing. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
