After the internal welding of the door leaf is completed by the robot arm and the first welding head, the clamping block is driven away from the door leaf by the clamping drive part, and then the sliding motor is started to drive the sliding screw to rotate, thereby driving the pushing block to slide. In this process, when the pushing block slides through the side wall of the door leaf, the second welding head approaches the side wall of the door leaf. When it moves to the position where welding is required, the second welding head is started for welding, thereby welding the side wall of the door leaf, thereby improving the applicability of the welding equipment.

When the clamping block 2 is close to the door leaf, the sliding motor 25 is started to drive the push block 4 to move through the sliding screw 251, and the push block 4 abuts against and pushes the door leaf until the other end of the door leaf abuts against the intercepting rod 27, thereby fixing the door leaf from all four sides. When the internal welding of the door leaf is completed, the clamping cylinder 121 is used to drive the clamping block 2 away from the door leaf, and the sliding motor 25 is continued to be started to drive the push block 4 to pass through the side of the door leaf. During this process, the second welding head 42 can be started to weld the side wall of the door leaf, further improving the production efficiency of welding.

[0037] To further improve the convenience of use, refer to Figure 2 and Figure 6 A rotating disk 13 is rotatably arranged on the surface of the workbench 1. The rotating disk 13 is arranged between two groups of conveying rollers 5. The top wall of the conveying rollers 5 is higher than the surface of the rotating disk 13. The rotating shaft of the rotating motor 111 passes through the top wall of the rotating chamber 11 and is coaxially fixedly connected with the rotating disk 13. The transmission assembly 7 includes a first transmission bevel gear 71, a second transmission bevel gear 72 and a plurality of transmission gears 73. The first transmission bevel gear 71 is coaxially fixedly arranged on the rotating shaft of the rotating motor 111. The second transmission bevel gear 72 is rotatably arranged in the rotating chamber 11 and meshed with the first transmission bevel gear 71. The transmission gear 73 is rotatably arranged in the rotating chamber 11 and is coaxially fixedly connected with the second transmission bevel gear 72. The transmission gear 73 meshes with the rotating gear 53. A lifting cylinder 8 is provided in the rotating chamber 11, and a plurality of lifting frames 81 are provided on the lifting cylinder 8. The conveying roller 5 is rotatably provided on the lifting frame 81. A square connecting shaft 531 is coaxially fixedly provided on the rotating gear 53. A square connecting groove 51 is provided on the rotating shaft of the rotating roller close to the rotating gear 53. The connecting shaft 531 can be inserted into the connecting groove 51. When the connecting shaft 531 is inserted into the connecting groove 51, the rotating motor 111 is started to drive the first transmission bevel gear 71 to rotate, drive the second transmission bevel gear 72 to rotate, and drive the rotating gear 53 to rotate through the transmission gear 73 to realize transmission. When the side wall of the door leaf is welded, the conveying roller 5 is driven by the lifting cylinder 8 to descend and disengage from the rotating groove 15, so that the connecting shaft 531 is disengaged from the connecting groove 51. At this time, the door leaf slowly falls on the rotating disk 13, and the rotating motor 111 is started again to drive the rotating disk 13 to rotate 90 degrees, so that the other two sides of the door leaf are welded through the second welding head 42. The alignment of the connecting shaft 531 and the connecting groove 51 is controlled by calculating the number of revolutions of the rotating gear 53 and the rotating shaft of the rotating motor 111. In another embodiment, a distance sensor can be set on the connecting shaft 531 or the rotating shaft of the conveying roller 5, and the control is performed by measuring the distance between the connecting shaft 531 or the rotating shaft of the conveying roller 5 and the inner wall of the rotating chamber 11.

[0038] To improve the convenience of use, refer to Figure 6A positioning groove 52 is provided on the rotating shaft of the rotating roller away from the rotating gear 53. A locking groove 82 communicating with the top wall is provided on the side wall of the lifting frame 81. The locking groove 82 communicates with the positioning groove 52. A locking block 83 is slidingly provided in the locking groove 82. A connecting spring 821 fixedly connected to the locking block 83 is fixedly provided on the inner bottom wall of the locking groove 82. The locking block 83 can be inserted into the positioning groove 52. A positioning hole 14 communicating with the rotating chamber 11 is provided on the side wall of the workbench 1. The workbench 1 is provided with a positioning bolt 141 that can be adapted to pass through the positioning hole 14 and be threadedly connected with the positioning hole 14. The positioning bolt 141 can abut against the locking block 83. When the conveying roller 5 does not rotate, the locking block 83 is inserted into the positioning groove 52, thereby controlling the connecting groove 51 to align with the connecting shaft 531. When the lifting frame 81 rises to insert the connecting shaft 531 into the connecting groove 51, the stop block 83 abuts against the positioning bolt 141, thereby sliding and compressing the connecting spring 821 in the locking groove 82, so that the stop block 83 is separated from the positioning groove 52, and the conveying roller 5 can rotate normally. When it is necessary to stop the conveying roller 5 from rotating, the positioning bolt 141 is screwed out, and the connecting spring 821 is restored to push the stop block 83 to slide. When the conveying roller 5 rotates so that the positioning groove 52 is aligned with the stop block 83, the stop block 83 is inserted into the positioning groove 52 under the push of the connecting spring 821, thereby locking the conveying roller 5.

[0039] The implementation principle of a civil air defense door welding device according to an embodiment of the present application is as follows: the lifting cylinder 8 is started to drive the lifting frame 81 to rise, so that the connecting shaft 531 is inserted into the connecting groove 51, and at the same time, the conveying roller 5 passes through the rotating groove 15 and is higher than the rotating disk 13. During this process, the positioning bolt 141 abuts against the stop block 83, so that the stop block 83 is disengaged from the positioning groove 52 and compresses the connecting spring 821. Then, the door leaf to be welded is placed on the conveying roller 5, and the rotating motor 111 is started. The rotating motor 111 drives the rotating gear 53 to rotate through the transmission assembly 7, and the conveying roller 5 rotates in one direction in the matching direction of the reversing gear 54, thereby driving the door leaf to move between the clamping blocks 2. At this time, the rotating motor 111 is stopped according to the number of revolutions of the rotating motor 111 so that the connecting groove 51 is vertically upward. The clamping cylinder 121 is started to drive the clamping block 2 to clamp the door leaf. In this process, the interception rod 27 is driven to move out of the interception groove 21 through the moving assembly 6. At the same time, the sliding motor 25 is started to drive the push block 4 to slide through the sliding screw 251. During the sliding process of the push block 4, the door leaf is pushed until the other end of the door leaf abuts against the interception rod 27 and the auxiliary block 271. Thus, the door leaf is fixed from four directions.

[0040] The conveying roller 5 is driven down by the lifting cylinder 8, so that the connecting shaft 531 is separated from the connecting groove 51, and the door leaf follows and slowly falls on the rotating disk 13. At this time, the mechanical arm 3 is started, and the door leaf accessories are adsorbed and placed in the door leaf by the electromagnet 31 on the mechanical arm 3, and the inside of the door leaf is welded by the first welding head 32 on the mechanical arm 3. After that, the clamping cylinder 121 is started to drive the clamping block 2 away from the door leaf, so that the second welding head 42 is close to the side wall of the door leaf, and the sliding motor 25 is started to drive the push block 4 to move through the side wall of the door leaf. In this process, the second welding head 42 welds the side wall of the door leaf. The height of the second welding head 42 can be adjusted according to the specifications of the side wall of the door leaf.

[0041] Then, the rotating motor 111 is started to drive the rotating disk 13 to rotate ninety degrees. The distance between the second welding head 42 and the side wall of the door leaf is adjusted by the clamping cylinder 121 according to the specifications of the door leaf. The sliding motor 25 is started again to drive the pushing block 4 to pass through the side wall of the door leaf, thereby welding the side wall of the door leaf through the second welding head 42.

[0042] Compared with manual welding, the device simplifies manual operation, reduces operation intensity, and reduces operator fatigue, thereby improving welding work efficiency. At the same time, compared with manual welding, the welding quality is improved through the control of the robot arm 3. The device can further improve the degree of automation by setting a controller and a distance sensor, thereby further improving work efficiency.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
