Description

Technical Field

[0002] Welding equipment refers to the equipment required to perform the welding process. Welding equipment includes welding machines, welding process equipment, and welding auxiliary equipment. The main types of welding equipment include electric welders, flame welding equipment, and other welding equipment. During the production of open barrels, welding equipment is required to weld the connecting lugs to the outer surface of the barrel body.

[0003] When welding barrel bodies, the position of the positioning column of the existing welding equipment cannot be adjusted, resulting in the welding equipment being able to only weld the connecting ears of barrel bodies with the same diameter and being unable to weld barrel bodies with different diameters. At the same time, when steps appear inside the barrel, it is easy to interfere with the fixation of the welding equipment, resulting in a decrease in the working range of the welding equipment, reducing the processing range of the welding equipment, and being unable to weld the connecting ears of different types of open barrels.

[0004] According to publication number CN104942501A, a barrel body connecting ear welding device includes a frame, a left heating welding head, a left cylinder, a right heating welding head, a right cylinder, and a limit platform, respectively arranged on the frame.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-5 The utility model provides a technical solution: a lug welding device, comprising a welding base 1, a positioning shell 2 fixedly connected to the top of the welding base 1, positioning columns 3 for positioning the barrel body are provided on both sides of the positioning shell 2, and a reset structure 4 for assisting the positioning column 3 in resetting is provided on the outer surface of the positioning column 3; through the setting of the reset structure 4, when the internal support for the positioning column 3 is canceled, the position of the positioning column 3 can be reset by the reset structure 4, which facilitates the readjustment of the positioning column 3;

[0029] Furthermore, the bottom end of the welding base 1 is provided with an adjustment mechanism 5 for adjusting the distance from the positioning column 3, and the top of the adjustment mechanism 5 is provided with a support column 6. The top of the support column 6 passes through the welding base 1 and is fixedly connected to a connecting seat 7. The top of the connecting seat 7 is rotatably connected to two groups of support rods 8 through an axle pin. The two groups of support rods 8 are arranged in a cross shape. When the adjustment mechanism 5 is started, the support column 6 is driven to move up and down, so that the support column 6 drives the connecting seat 7 to move, and the connecting seat 7 drives the two groups of support rods 8 at the top to move up and down;

[0030] Specifically, a movable seat 9 is provided on the outer surface of the support column 6, a through hole is provided at the center of the movable seat 9, the inner cavity of the through hole of the movable seat 9 is plugged and slid with the support column 6, the top of the movable seat 9 is fixedly connected with an adjusting shell 10, the surface of the adjusting shell 10 is provided with an adjusting groove 11, the support rod 8 is movably connected to the inner cavity of the adjusting groove 11, and the bottom end of the movable seat 9 is provided with a supporting structure 12 for supporting the movable seat 9. By adjusting the cooperation between the shell 10 and the support rod 8, the support rod 8 can be adjusted after sliding in the adjusting groove 11. The angle of the support rod 8 can be adjusted, and the angle of the support rod 8 can be adjusted so that the support distance of the support rod 8 to the positioning column 3 can be adjusted, thereby realizing the adjustment of the position of the positioning column 3;

[0031] Preferably, both ends of the welding base 1 are provided with welding modules 16 for welding the connecting ears, and the connecting ears are welded to the outer surface of the barrel body through the welding modules 16 at both ends.

[0032] In addition, the reset structure 4 includes a connecting rod 41, which is arranged on both sides of the outer surface of the positioning column 3. A movable groove 42 is opened on the surface of the positioning shell 2. The connecting rod 41 is slidably connected to the inner cavity of the movable groove 42. A spring 43 is provided between the two groups of connecting rods 41 for pulling the positioning column 3 to reset. When the positioning column 3 moves, it drives the connecting rod 41 to move, so that the connecting rods 41 at both ends move in the movable groove 42, stretching the spring 43. After the support for the positioning column 3 is cancelled, the spring 43 resets and pulls the connecting rods 41 at both ends to move, so that the positioning column 3 is reset, which is convenient for re-adjusting the position of the positioning column 3.

[0033] Furthermore, the adjusting mechanism 5 includes a lifting frame 51, which is fixedly connected to the bottom end of the welding base 1. A first cylinder 52 is fixedly installed at the bottom end of the lifting frame 51. The piston end of the first cylinder 52 passes through the lifting frame 51 and is provided with an adjusting component. The top end of the adjusting component is bolted to the bottom end of the support column 6. Starting the first cylinder 52 pushes the adjusting component to move, so that the adjusting component pushes the support column 6 to move.

[0034] Preferably, the adjustment component includes a second cylinder 53, the bottom end of the second cylinder 53 is bolted to a support seat 54, the bottom end of the support seat 54 is bolted to the piston end of the first cylinder 52, and the piston end of the second cylinder 53 is bolted to the bottom end of the support column 6. When the second cylinder 53 is started, the support column 6 is pushed to move by the piston end of the second cylinder 53, so that the height of the support rod 8 at the top of the support column 6 can be adjusted. The support seat 54 can be pushed to move by the piston end of the first cylinder 52, and the height of the second cylinder 53 can be adjusted.

[0035] The supporting structure 12 includes a movable sleeve 121 and a movable rod 122. The movable sleeve 121 is plugged and fixed on the surface of the welding base 1. The inner cavity of the movable sleeve 121 is plugged and slid with the movable rod 122. The top end of the movable rod 122 is fixedly connected to the bottom end of the movable seat 9. The bottom end of the movable rod 122 is fixedly connected to the top end of the support seat 54. Through the setting of the movable sleeve 121 and the movable rod 122, the movable seat 9 and the support seat 54 are connected, which improves the stability of the movable seat 9 and the support seat 54 when they are raised and lowered.

[0036] Specifically, four groups of movable sleeves 121 are provided, and the four groups of movable sleeves 121 are symmetrically distributed on the upper surface of the welding base 1. Through the setting of the movable sleeves 121, the movable seat 9 and the support seat 54 are positioned on all sides to avoid the angle of the movable seat 9 and the support seat 54 from being offset during lifting and lowering, thereby improving the stability of the movable seat 9 and the support seat 54 when moving.

[0037] Preferably, the top of the movable seat 9 is fixedly connected to a support plate 13, and a limiting ring 14 is provided at the top of the support plate 13. The upper surface of the support plate 13 fits with the surface of the positioning column 3. The movable seat 9 drives the support plate 13 to move, so that the support plate 13 drives the limiting ring 14 at the top to move. The position of the positioning column 3 is limited by the limiting ring 14 to avoid the connection rod 41 from colliding with the other end of the movable groove 42 when the positioning column 3 is reset.

[0038] Preferably, a mounting hole is opened on the surface of the welding base 1, and a limiting column 15 is inserted and fixed in the inner cavity of the mounting hole. The limiting column 15 is located between the support seat 54 and the movable seat 9. Through the setting of the limiting column 15, the rising height of the support seat 54 is limited to avoid collision with the welding base 1, and the descending height of the movable seat 9 is limited to avoid collision between the movable seat 9 and the welding base 1.

[0039] When in use, place the open barrel on the welding base 1, cover the positioning shell 2, start the first cylinder 52 to push the support seat 54 to move to a certain distance, and then start the second cylinder 53 to push the support column 6 to move upward. The support column 6 drives the cross-shaped support rod 8 to move upward through the connecting seat 7. The support rod 8 slides in the inner cavity of the adjustment groove 11, so that the angle of the support rod 8 changes when it moves upward. The two groups of support rods 8 extend outward to support the positioning column 3, pushing the positioning column 3 to move. The positioning columns 3 at both ends move toward the inner wall of the barrel body to position the barrel body. At the same time, when the positioning column 3 moves, the spring 43 is stretched through the connecting rod 41, and then the welding module is started to weld the connecting ear to the surface of the open barrel. When the positioning is cancelled, the second cylinder 53 drives the support column 6 to move downward, so that the support rod 8 moves downward, and the support rod 8 retracts into the inner cavity of the adjustment shell 10 to cancel the support for the positioning column 3. Finally, the spring 43 contracts and drives the connecting rods 41 at both ends to move, so that the positioning column 3 is reset, thereby improving the working range of the welding equipment and increasing the processing range of the welding equipment, so that the connecting ears of different types of open barrels can be welded.
