The rear joint positioning seat has a slot that matches the tube body, and the rear joint positioning seat also has a slot that matches the rear joint. Two supports are symmetrically installed around the slots on the upper surface of the rear joint positioning seat. A rotating pin is rotatably connected to each support, and a column is rotatably connected to the rotating pin. The front joint positioning seat is slidably connected to the column. The front joint positioning seat has a slot that matches the front joint, and a positioning pin can be inserted and removed from the column. The positioning pin abuts against the front joint positioning seat.

[0006] Preferably, the support is specifically positioned on the rear connector positioning seat by a support positioning pin, and the support is specifically fixed on the rear connector positioning seat by a set screw.

[0007] Preferably, a handling handle is fixedly connected to both sides of the rear connector positioning seat.

[0008] Compared with the prior art, the present invention provides a temporary welding device for the joint of missile tube and wing, which has the following advantages: The upper surface of the rear joint positioning seat is rotatably connected to two columns. The front joint positioning seat installed on the columns positions and temporarily welds the front joint, and the rear joint positioning seat positions and temporarily welds the rear joint, ensuring the positional tolerance requirements of the front and rear joints. After welding, the positioning pin of the positioning seat is pulled out, allowing the front joint positioning seat to slide downwards along the columns, completing the separation of the front joint positioning seat from the front joint. At this point, the columns can be opened to both sides to remove the tube. This significantly improves the positioning welding efficiency, and the tooling is convenient to operate. The ingenious design reduces the loss of manpower, material resources, and financial resources, making it highly practical. Attached Figure Description

[0016] Reference Figure 1-4 A temporary welding device for the joint between a missile tube and a wing includes a tube body 101, a front joint 102, and a rear joint 103;

[0017] Specifically, the cylinder 101 is temporarily welded to the outer wall of the cylinder 101 by a temporary welding device, which includes a rear connector 102 and a rear connector 103. The temporary welding device comprises a rear connector positioning seat 104, a front connector positioning seat 105, a column 106, a support 107, and a rotating pin 109. The rear connector positioning seat 104 has a slot matching the cylinder 101, and the rear connector positioning seat 105 also has a slot matching the rear connector 103. 4. Two supports 107 are symmetrically installed around the slot on the upper surface. Each support 107 is rotatably connected to a rotating pin 109. A column 106 is rotatably connected to the rotating pin 109. A front connector positioning seat 105 is slidably connected to the column 106. The front connector positioning seat 105 is provided with a slot that matches the front connector 102. A positioning seat positioning pin 110 can be inserted and removed on the column 106. The positioning seat positioning pin 110 abuts against the front connector positioning seat 105.

[0018] Specifically, the support 107 is positioned on the rear connector positioning seat 104 by the support positioning pin 201, and the support 107 is fixed on the rear connector positioning seat 104 by the set screw 202.

[0019] Specifically, the rear connector positioning seat 104 is fixedly connected to both sides with a handling handle 108.

[0020] Working principle:

[0021] During the welding of the front connector 102 and the rear connector 103, the cylinder 101 is inserted into the slots provided on the rear connector positioning seat 104. The rear connector 103 is then sequentially inserted into the slots provided on the rear connector positioning seat 104, and a temporary weld is applied to the rear connector 103 to fix it to the cylinder 101. Next, the two side columns 106 are erected, and the front connector 102 is placed into the slots provided on the front connector positioning seat 105 on the column 106. The front connector 102 is then temporarily welded to fix it to the cylinder 101. At this point, the temporary welding is complete, and the two side columns 106 are connected via the front connector... The head positioning seat 105 and the front connector 102 are mutually limited and fixed. The operator pulls out the positioning pin 110 of the positioning seat, causing the front connector positioning seat 105 to slide down the column 106. At this time, the front connector positioning seat 105 is separated from the front connector 102. The column 106 can then be opened to both sides, and the operator can take out the cylinder 101 by lifting it up. When using it again, the front connector positioning seat 105 is moved up along the column 106 and fixed on the column 106 by the positioning pin 110. At this time, the tooling is reset. The operation is simple and the positioning is accurate, which makes it highly practical.
