[0020] Furthermore, the fixed block 4 forms a horizontal pushing structure through the first screw 2, the first slider 3 and the operating table 1, so that the position of the horizontal limit assembly of the plate 13 can be easily adjusted through the first screw 2, thereby preventing the horizontal limit assembly from hindering the movement of the vertical limit assembly when vertical welding is performed between the plates 13.

[0021] Furthermore, under the action of the electric push rod 5, the support plate 7 forms a vertical lifting structure through the telescopic arm 6 and the fixed block 4, so that the horizontal limit assembly of the plate 13 is driven to rise and fall through the electric push rod 5, and then when the plate 13 is vertically welded, it is ensured that the two groups of plates 13 can be in an aligned state.

[0022] The upper end surface of the supporting plate 7 is provided with sliding grooves at the front and rear respectively, and the first hollow rods 8 are inserted at both ends of the sliding grooves respectively, and the second springs 11 are connected between the first hollow rods 8, the first hollow rod 8 is inserted with the first telescopic rod 9 inside, and the first hollow rod 8 is provided with a first spring 10 at the bottom, the upper end of the first spring 10 is connected to the first telescopic rod 9, and the upper end of the first telescopic rod 9 is connected to a limit plate 12, and a plate 13 is placed on the operating table 1 below the limit plate 12. It should be additionally explained that the second spring 11 is embedded in the sliding groove on the supporting plate 7 to prevent the second spring 11 from being displaced during the extrusion and contraction process.

[0023] Furthermore, the limit plate 12 forms an elastic telescopic structure with the operating table 1 through the first hollow rod 8, the first telescopic rod 9, the first spring 10, and the two groups of first hollow rods 8 also form an elastic telescopic structure through the second spring 11, so that the limit plate 12 and the supporting plate 7 can elastically squeeze and limit the plate 13 through the first spring 10, and the position of the limit plate 12 can be easily adjusted through the second spring 11, thereby avoiding the limit plate 12 from hindering the operation of the staff during welding.

[0024] The operating table 1 is respectively inserted with a second screw rod 14 on both sides, and the other end of the second screw rod 14 is inserted on the second slider 15 inside the operating table 1, a fixing plate 16 is provided above the second slider 15, and the fixing plate 16 is respectively provided with a slide groove on the opposite surface, two groups of slide rods 17 are inserted in the slide groove, and the other end of the slide rod 17 is connected to an L-shaped limit plate 18, the L-shaped limit plate 18 is provided with a second hollow rod 19 on one side, and another group of L-shaped limit plates 18 is correspondingly provided with a second telescopic rod 20 on one side, the second telescopic rod 20 is inserted in the second hollow rod 19, and the second hollow rod 19 is provided with a third spring 21 inside, and the other end of the third spring 21 is connected to the inside of the second telescopic rod 20.

[0025] Furthermore, the fixed plate 16 forms a horizontal pushing structure with the operating table 1 through the second screw 14, the second slider 15, so that the position of the vertical limit assembly of the plate 13 can be easily adjusted through the second screw 14, and the L-shaped limit plate 18 forms an elastic extrusion limit structure with the plate 13 through the second hollow rod 19, the second telescopic rod 20, and the third spring 21, so that the L-shaped limit plate 18 can extrude and limit the plate 13 in the vertical state through the third spring 21, so that the plates 13 can be welded.

[0026] Working principle: When using the positioning device for welding home sheet metal panels, first, when two groups of panels 13 are horizontally welded, the vertical limit assembly can be moved to both sides by the second screw 14, so that the horizontal limit assembly can be moved to a suitable position by the first screw 2. When the position adjustment of the limit assembly is completed, the limit plate 12 can be pulled upward, so that the panel 13 is inserted between the limit plate 12 and the supporting plate 7. After the panel 13 is inserted to a suitable position, the limit plate 12 can be released, and the first spring 10 returns to its original state after losing its tension, so that the panel 13 is elastically squeezed and limited by the limit plate 12 and the supporting plate 7; during the welding process of two groups of horizontally placed panels 13, the position of the limit plate 12 can be moved by the second spring 11, so as to avoid the limit plate 12 causing obstruction to the work process of the staff. The two sets of L-shaped limit plates 18 are then pulled to the sides to vertically place the plates 13 between the L-shaped limit plates 18, and the two sets of L-shaped limit plates 18 are used to elastically squeeze and limit the plates 13 in the vertical state under the action of the third spring 21; when the plates 13 in the vertical state are limited, the electric push rod 5 can be started, thereby driving the supporting plate 7 to rise and fall through the electric push rod 5, thereby ensuring that the required welding positions of the two sets of plates 13 are in a horizontal state, thereby facilitating the welding of the two sets of plates 13 in the vertical state. This is the use process of the positioning device for welding home sheet metal plates.
