Detailed implementation manners

[0021] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0022] The column welding device of the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0023] As Figures 1 - 4 shown, the column welding device of the embodiment of the present invention may include a workbench 10, two support mechanisms 50, a lifting mechanism 60, two fixing mechanisms 70 and a welding mechanism 80.

[0024] Among them, support plates 11 are arranged on both sides of the top surface of the workbench 10. One side of the support plate 11 is connected with a first electric push rod 20, and the piston end of the first electric push rod 20 is connected with an L-shaped plate 21.

[0025] It can be understood that by setting the first electric push rod 20, the distance between the two L-shaped plates 21 can be adjusted to adapt to columns of different lengths.

[0026] Two support mechanisms 50 are respectively arranged on one side of the two L-shaped plates 21. The support mechanism 50 is connected with a toothed ring 30. The L-shaped plate 21 is slidably connected with a rack 40. The rack 40 meshes with the toothed ring 30. The workbench 10 is provided with a through hole 12 matching the rack 40.

[0027] The lifting mechanism 60 is arranged on the top surface of the workbench 10. The lifting mechanism 60 is slidably connected with the rack 40.

[0028] It should be noted that the lifting mechanism 60 can drive the rack 40 to move up and down, so as to drive the toothed ring 30 to rotate reciprocally, so as to rotate the column and weld it around one week. By setting the support mechanism 50, the toothed ring 30 can be supported during the rotation process.

[0029] The fixing mechanism 70 is arranged on the inner wall of the gear ring 30.

[0030] The welding mechanism 80 is arranged on the top surface of the workbench 10.

[0031] Specifically, the staff passes the two columns through the gear rings 30 on both sides respectively, and then clamps and fixes the two columns through the two fixing mechanisms 70 respectively. After fixing, the first electric push rod 20 is started to drive the L-shaped plate 21 to move, so as to adjust the distance between the two columns to make the two columns butt. Then, the welding mechanism 80 is controlled to approach the butt joint of the two columns, and the lifting mechanism 60 is started to drive the rack 40 to move up and down, and then drive the gear ring 30 and the column to rotate, so that the welding mechanism 80 welds around it for one week. After welding, the fixation of the column is released and it is taken off.

[0032] The column welding device of the embodiment of the utility model can automatically perform welding operations around the column for one week, without too much manual operation, thus effectively ensuring the welding quality.

[0033] In an embodiment of the present utility model, as Figure 3 shown, the supporting mechanism 50 may include an annular groove 51 and a plurality of moving rods 52. Among them, the annular groove 51 is opened on one side of the L-shaped plate 21, and the plurality of moving rods 52 are respectively connected to the gear ring 30, and the moving rods 52 extend into the annular groove 51.

[0034] It can be understood that during the rotation of the gear ring 30, the plurality of moving rods 52 will move in the annular groove 51 to support the gear ring 30.

[0035] In an embodiment of the present utility model, as Figure 1 shown, the lifting mechanism 60 may include a second electric push rod 61 and a lifting plate 62. Among them, the second electric push rod 61 is arranged on the top surface of the workbench 10, the lifting plate 62 is connected to the piston end of the second electric push rod 61, and the lifting plate 62 penetrates through the two racks 40 respectively.

[0036] It should be noted that by controlling the telescopic movement of the piston end of the second electric push rod 61, the lifting plate 62 and the rack 40 can be driven to move up and down, and the rack 40 can slide on the lifting plate 62 to adapt to the position change of the L-shaped plate 21.

[0037] In an embodiment of the present utility model, as Figure 4 shown, the fixing mechanism 70 may include two third electric push rods 71 and two arc-shaped clamping plates 72. Among them, the two third electric push rods 71 are oppositely arranged on the inner wall of the gear ring 30, and the arc-shaped clamping plates 72 are connected to the piston ends of the third electric push rods 71.

[0038] It can be understood that by controlling the telescopic movement of the piston end of the third electric push rod 71, the arc-shaped clamping plate 72 can be driven to move, and the column can be clamped and fixed by the cooperation of the two arc-shaped clamping plates 72.

[0039] In an embodiment of the present invention, as Figure 1 shown, the welding mechanism 80 may include a mounting frame 81, a fourth electric push rod 82 and a welding torch 83. Among them, the mounting frame 81 is arranged on the top surface of the workbench 10, the fourth electric push rod 82 is connected to the mounting frame 81, the fourth electric push rod 82 is located on the front side of the lifting plate 62, and the welding torch 83 is connected to the piston end of the fourth electric push rod 82.

[0040] It should be noted that the two columns can be welded by the welding torch 83, and the height of the welding torch 83 can be adjusted by the fourth electric push rod 82 to adapt to the position of the column.

[0041] In an embodiment of the present invention, as Figure 2 shown, the L-shaped plate 21 is provided with a chute 211, and a slider 41 is slidably connected in the chute 211. The slider 41 is connected to the rack 40.

[0042] It can be understood that during the up and down movement of the rack 40, the slider 41 cooperates with the chute 211 to guide it, making its movement more stable.

[0043] Specifically, the staff passes the two columns through the tooth rings 30 on both sides respectively, and then drives the arc-shaped clamping plate 72 to move by the third electric push rod 71, and clamps and fixes the columns by the cooperation of the two arc-shaped clamping plates 72. After fixing, the first electric push rod 20 is started to drive the L-shaped plate 21 to move, and the rack 40 slides on the lifting plate 62, so as to adjust the distance between the two columns and make the two columns butt.

[0044] The fourth electric push rod 82 is started to adjust the height of the welding torch 83 to make it close to the butt joint part of the two columns. Then the second electric push rod 61 is started to drive the lifting plate 62 and the rack 40 to move up and down, and further drive the tooth ring 30 and the column to rotate, so that the welding torch 83 welds around it for one week. After welding, the fixation of the column is released and it is taken off.

[0045] In summary, the column welding device of the embodiment of the present invention can automatically perform welding operations around the column for one week, without too much manual operation, thus effectively ensuring the welding quality.
