Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Please refer to Figures 1 to 7 An aluminum metal piece welding tool, comprising a fixed block 1, a baffle 101 fixedly installed at the lower end of the fixed block 1, the baffle 101 is used to block the molten material at the welding position, a sealing assembly 2 is installed on both sides of the fixed block 1, the baffle 101, the fixed block 1 and the sealing block 201 can be made of ceramic material or other material which will not melt;

[0035] The fixed block 1 is provided with a guide groove 102 at both ends, the sealing assembly 2 comprises a sealing block 201 slidingly installed in the guide groove 102, the sealing block 201 is fixedly installed with an extrusion spring 202 at one end close to the inner wall of the guide groove 102, the extrusion spring 202 is fixedly connected with the inner wall of the guide groove 102 at the end away from the sealing block 201, and the lower end of the sealing block 201 is in sliding contact with the upper end of the baffle 101;

[0036] The fixed block 1 is provided with a fixed rod 103 rotatably installed at the upper end, the welding head 104 is rotatably installed on the outside of the fixed rod 103 through a rotating seat, and the welding head 104 is located on the upper side of the baffle 101;

[0037] A driving assembly 3 is slidably installed inside the fixed rod 103, and is used to drive the fixed block 1 to rotate. The driving assembly 3 comprises a push rod 301 slidably installed inside the fixed rod 103, and the lower outer wall of the push rod 301 is embedded with a ball 302. The fixed block 1 is provided with a movable slot 105 corresponding to the lower side of the push rod 301, and the inner wall of the movable slot 105 is provided with a threaded groove 106. The threaded groove 106 is a quarter of a circle in thread, and the ball 302 is located inside the threaded groove 106, and the push rod 301 is pressed against the inner wall of the threaded groove 106 through the ball 302.

[0038] By adopting the above technical scheme, when welding is needed, the staff first places the plate to be welded at the designated work site, leaves a welding gap between the two plates, and tilts the plate at a certain angle before welding. The device is rotated so that the baffle 101 is aligned with the gap reserved when the plate is welded. Then, the baffle 101 is passed between the two plates to be welded, and the fixed block 1 is rotated to maintain a vertical state. At this time, the baffle 101 is located below one of the plates to be welded. The push rod 301 is then pushed down, which causes the push rod 301 to descend and the ball 302 to press against the threaded groove 106. At this time, under the decomposing force of the pressing force, the fixed block 1 can drive the baffle 101 at its lower end to rotate and turn ninety degrees. The baffle 101 after rotation can be located below both plates to be welded. In the process of rotating the baffle 101, the fixed block 1 can press against the outer wall of the sealing block 201 through the guide slot 102, causing the sealing block 201 to rotate. When the sealing block 201 rotates, the side of the sealing block 201 located outside the guide slot 102 can contact the plate to be welded, thereby pressing the compression spring 202 when it is pressed, causing the compression spring 202 to contract. When the fixed block 1 is rotated by ninety degrees, the outer wall of the sealing block 201 can be attached to the two plates. Then, the welding head 104 is used to weld the reserved gap. The fixed block 1 needs to be on the lower side of the plate to be welded.

[0039] A moving slot 107 is formed on one side of the fixed block 1, and a sealing plate 108 is slidably installed inside the moving slot 107.

[0041] By adopting the above technical scheme, when the fixed block 1 rotates relative to the fixed rod 103, the pressure receiving block 113 on the sealing plate 108 can move in the extrusion groove 123 and gradually approach the inclined part of the extrusion groove 123, when the fixed block 1 rotates by 90 degrees, the pressure receiving block 113 drives the sealing plate 108 to move in the moving groove 107 and extrude the reset spring 112 under the action of the extrusion force, when the sealing plate 108 moves, the air passage 109 on the sealing plate 108 can be communicated with the air inlet 110 and the air outlet 111 at the same time, at this time, the external gas supply device can transmit gas into the welding head 104 through the hose, so that the welding head 104 can work by ignition, and similarly, when the pressure receiving block 113 is located in the extrusion groove 123 and does not contact the inclined part on the extrusion groove 123, the reset spring 112 can extrude the sealing plate 108 under the action of the elastic force of the reset spring 112, so that the sealing plate 108 moves to the initial position, so that the opening position of the air passage 109 deviates from the positions of the air inlet 110 and the air outlet 111, so as to cut off the gas flow into the welding head 104.

[0042] The baffle 101 is internally provided with a cavity 114, the cavity 114 is internally filled with a thermal expansion liquid, the fixed block 1 is internally provided with a through groove 115, and the through groove 115 is communicated with the inside of the cavity 114, the fixed block 1 is in a “T” type structure, and the protruding part on the upper side of the fixed block 1 is provided with a sliding groove 116, the sliding groove 116 is internally slidably installed with a sliding block 117, one end of the sliding block 117 is fixedly installed with a pressing plate 118, the pressing plate 118 extrudes the aluminum metal piece in cooperation with the baffle 101, and the lower end of the sliding block 117 is fixedly installed with a supporting spring 119, the supporting spring 119 extrudes the sliding block 117;
