[0026] The utility model discloses a multi-directional welding device for an electric switch cabinet, which is mainly used in the scene where a straight seam welding machine has great welding limitations and low efficiency.

[0027] Reference Figure 1-Figure 9 A multi-directional welding device for an electric switch cabinet comprises a welding frame 1, a welding head 2 is movably arranged on the lower surface of the welding frame 1, a rotating seat 3 is arranged below the welding frame 1, a motor is arranged inside the rotating seat 3, an adjusting frame 4 is fixedly connected to the output end of the motor, a transmission steel belt 5 is arranged on the surface of the adjusting frame 4, a moving seat 6 is fixedly arranged on the surface of the transmission steel belt 5, a bearing assembly 7 is rotatably arranged on the upper surface of the moving seat 6, a feeding conveyor belt 8 is arranged on the left side of the rotating seat 3, a switch cabinet housing 9 is transmitted on the surface of the feeding conveyor belt 8, a unloading conveyor belt 10 is arranged on the rear side of the rotating seat 3, the bearing assembly 7 comprises an outer shell 701 rotatably arranged on the upper surface of the moving seat 6, a telescopic inner shell 705 is lifted and lowered inside the outer shell 701, a plurality of inner support blocks 708 which can be turned outward are arranged on the outer surface of the telescopic inner shell 705, and the turned outward inner support blocks 708 can contact the inner wall of the switch cabinet housing 9, and the transmission steel belt 5 can drive the switch cabinet housing 9 on the bearing assembly 7 to be vertically and horizontally for welding operation.

[0028] In this embodiment, the feeding conveyor belt 8 is first provided to convey the switch cabinet housing 9 to one side of the adjusting frame 4, and then the rotating seat 3 is provided to drive the adjusting frame 4 to rotate to the direction of the feeding conveyor belt 8, and then the transmission steel belt 5 drives the moving seat 6 and the bearing assembly 7 to move to the top of the adjusting frame 4, and makes the outer shell 701 horizontal, and the telescopic inner shell 705 inside the outer shell 701 will extend outward and be inserted into the switch cabinet housing 9, and then the inner support block 708 on the outer surface of the telescopic inner shell 705 will turn outward and fit the inner wall of the switch cabinet housing 9, and then the rotating seat 3 and the bearing assembly 7 are reset, at this time Figure 6 As shown, the switch cabinet housing 9 is vertical, and the upper welding head 2 can weld the end surface of the switch cabinet housing 9. After welding, the bearing assembly 7 is adjusted to a horizontal state by the transmission steel belt 5 again, and the housing 701 is rotated forty-five degrees so that the corners of the switch cabinet housing 9 face upwards, as shown in FIG. Figure 5As shown, the switch cabinet housing 9 is welded by the upper welding head 2, and after welding the corners on one side, the position of the switch cabinet housing 9 can be switched by rotating the outer shell 701 to weld the other corners until the four corners of the outer circumference are welded. Finally, the horizontal switch cabinet housing 9 can be driven by the rotating seat 3 to be transferred to the direction of the unloading conveyor belt 10. By extending the telescopic inner shell 705, the welded switch cabinet housing 9 can be unloaded to the surface of the unloading conveyor belt 10, thereby completing the entire welding work. The entire process does not require manual operation, the processing efficiency is higher, and the welding range is more comprehensive.

[0029] Specifically, the outer surface of the adjustment frame 4 is in the shape of a quarter arc, and the transmission steel belt 5 is embedded in the quarter arc surface. When the transmission steel belt 5 drives the moving seat 6 and the bearing assembly 7 to move to the lowest end, the switch cabinet housing 9 on the bearing assembly 7 is vertical at this time. If it moves to the uppermost end, it is horizontal. The welding head 2 can use a laser welding head and can move along the X-axis, Y-axis, and Z-axis directions.

[0030] Specifically, a driving motor is arranged inside the movable seat 6, and the output end of the driving motor is fixedly connected to the lower end of the shell 701. The driving motor can drive the shell 701 to rotate, thereby switching the position of the switch cabinet shell 9, which is convenient for welding operations at other corners.

[0031] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8 An electric push rod 702 is arranged inside the outer shell 701. The telescopic end of the electric push rod 702 is in contact with the lower end of the telescopic inner shell 705 but not fixed. A circular hole 706 is opened at the lower end of the telescopic inner shell 705. The telescopic end of the electric push rod 702 is fixedly connected with a push block 703. The push block 703 can pass through the circular hole 706 and squeeze the inner support block 708 through the extension of the electric push rod 702. The push block 703 has resistance when passing through the circular hole 706. A plurality of limit spring blocks 704 are elastically arranged on the outer surface of the push block 703.

[0032] In this embodiment, during the process of loading the switch cabinet housing 9, the electric push rod 702 pushes the push block 703 and squeezes the telescopic inner shell 705 to extend outward. After the telescopic inner shell 705 extends to the limit position, the telescopic inner shell 705 cannot continue to extend. At this time, the electric push rod 702 continues to push the push block 703, and the limiting spring block 704 on the outer surface of the push block 703 will be squeezed by the circular hole 706 and shrink inward, so that the push block 703 passes through the circular hole 706. At this time, the push block 703 can continue to extend through the push of the electric push rod 702, and squeeze the inner support block 708 inside the telescopic inner shell 705, so that it flips outward and contacts the inner wall of the switch cabinet housing 9. In this way, the bearing assembly 7 can stably drive the switch cabinet housing 9 to transfer to the bottom of the welding head 2 for welding operation.

[0033] Among them, Fig.10 As shown, the lower edge of the telescopic inner shell 705 is provided with a limit convex strip 11. When the telescopic inner shell 705 is extended to the limit position by the electric push rod 702, the limit convex strip 11 prevents the telescopic inner shell 705 from detaching from the outer shell 701. At this time, the telescopic inner shell 705 cannot continue to extend. For details, refer to Figure 3 It can be seen that the outer opening size of the limiting ridge 11 is consistent with the inner cavity size of the outer shell 701, and the outer opening size of the telescopic inner shell 705 is consistent with the upper opening of the outer shell 701, and the outer opening size of the limiting ridge 11 is larger than the upper opening of the outer shell 701, so the limiting ridge 11 cannot be detached from the upper opening of the outer shell 701.

[0034] It should be noted that the resistance between the limiting spring block 704 and the circular hole 706 must be greater than the total weight of the telescopic inner shell 705 and the inner support block 708 to prevent the electric push rod 702 from directly passing through the circular hole 706 and failing to play a driving role when it first starts to push the telescopic inner shell 705 to extend.

[0035] Specifically, Figure 3 and Fig. 9 As shown, four groups of notches 707 are provided on the outer surface of the telescopic inner shell 705, the lower end of the inner support block 708 elastically rotates on the inner wall of the notch 707, the upper end of the inner support block 708 is provided with an extrusion portion 7081 on the side close to the outer shell 701, and the upper end of the inner support block 708 is provided with an inclined pressure portion 7082 on the side away from the outer shell 701.

[0036] In this embodiment, the extrusion portion 7081 of the inner support block 708 is in contact with the inner wall of the switch cabinet housing 9 to increase the force-bearing area, and the inclined pressure-bearing portion 7082 will flip outward from the slot 707 when receiving the pushing force of the push block 703. When the push block 703 does not apply pressure to the inner support block 708, the inner support block 708 will automatically rotate and reset, and the reset function is mainly achieved through the elastic rotating shaft.

[0037] The complete working principle of the present application is as follows: the feeding conveyor belt 8 conveys the switch cabinet housing 9 to one side of the adjustment frame 4, and then the motor in the rotating seat 3 drives the adjustment frame 4 to rotate to the direction of the feeding conveyor belt 8, and then the transmission steel belt 5 drives the moving seat 6 and the bearing assembly 7 to move to the top of the adjustment frame 4, and makes the housing 701 present a horizontal state;

[0038] Then the electric push rod 702 pushes the push block 703 and squeezes the telescopic inner shell 705 to extend outward. After the telescopic inner shell 705 extends to the limit position, the telescopic inner shell 705 cannot continue to extend. At this time, the electric push rod 702 continues to push the push block 703, and the limit spring block 704 on the outer surface of the push block 703 is squeezed by the circular hole 706 and shrinks inward, so that the push block 703 passes through the circular hole 706. At this time, the push block 703 can continue to extend through the push of the electric push rod 702 and squeeze the inner support block 708 inside the telescopic inner shell 705, so that it turns outward and contacts and squeezes the inner wall of the switch cabinet housing 9;

[0039] At this time, the motor in the rotating seat 3 continues to drive the bearing assembly 7 and the switch cabinet housing 9 to reset, and the transmission steel belt 5 drives the moving seat 6 and the bearing assembly 7 to reset, so that the switch cabinet housing 9 returns to the vertical state, and the upper welding head 2 can weld the end surface of the switch cabinet housing 9. After welding, the electric push rod 702 drives the push block 703 to shrink and reset, and the switch cabinet housing 9 also drops accordingly. Then the bearing assembly 7 is adjusted to a horizontal state again by the transmission steel belt 5, and the shell 701 rotates forty-five degrees at the same time, so that the corners of the switch cabinet housing 9 face upwards, as shown in FIG. Figure 5 As shown, the upper welding head 2 is used for welding, and after welding one side of the corner, the other corner can be welded by rotating the housing 701 to switch the position of the switch cabinet housing 9 until all four corners of the outer peripheral surface are welded;

[0040] Finally, the horizontal switch cabinet housing 9 can be driven by the rotating seat 3 to be transferred to the direction of the unloading conveyor belt 10. By extending the telescopic inner shell 705, the welded switch cabinet housing 9 can be unloaded to the surface of the unloading conveyor belt 10, thereby completing the entire welding work.

[0041] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
