In the welding process, in order to ensure that the sealing ring A3 is kept pressed, poor air tightness caused by the fact that the sealing ring A3 is not kept pressed is avoided, the welding process cannot be interrupted, welding needs to be finished at one time, however, the pressing piece necessarily shields the partial edge of the pole A4, and therefore the pressing piece needs to be avoided from an overlapped part in the welding process.
Referring to fig. 2, the conventional battery cover plate pole welding tool includes a bottom plate 101 for supporting a battery cover plate a, a supporting platform 102 disposed above the bottom plate 101, and a rotating and pressing mechanism disposed on the bottom plate 101, where the rotating and pressing mechanism includes a pressing cylinder 103 vertically disposed below the supporting platform 102, a vertical guide rail 104 vertically disposed on a side of the supporting platform 102, a connecting block 105 disposed on the vertical guide rail 104 and connected to a transmission end of the pressing cylinder 103, a rotating shaft 106 disposed on the connecting block 105, a gear 107 disposed on an outer periphery of the rotating shaft 106, a rack 108 engaged with the gear 107, a rotating and driving cylinder (not shown) for driving the rack 108 to move linearly, an "Contraband" shaped connecting frame 110 disposed on the rotating shaft 106, and a pressing piece 111 disposed on the "Contraband" shaped connecting frame 110. The rotary pressing mechanism realizes the pressing and rotating functions of the pressing piece 111 through the linkage of the rotary mechanism and the pressing mechanism, the pressing cylinder 103 is located under the pole A4, the vertical guide rail 104 is located on one side of the pressing cylinder 103, and the connecting block 105 is arranged in the middle of the pressing cylinder 103 and the vertical guide rail 104 for being connected with the vertical guide rail 104 and the cylinder. The rotating shaft 106 needs to be located right below the pole a4 to be coaxially arranged with the pole a4, the inner end of a first transverse portion 1101 at the bottom of the Contraband-shaped connecting frame 110 is connected with a vertical output shaft (rotating shaft 106) at the upper end of the rotary pressing mechanism, the inner end of a second transverse portion 1102 at the top of the Contraband-shaped connecting frame 110 is connected with the pressing piece 111, and the battery cover plate a is located in the hollow portion 1103 of the Contraband-shaped connecting frame 110. Vertical output shaft and "Contraband" structure lead to setting up supporting bench, base and connection structure etc. that the structure is more complicated, need make supporting bench, base, connection structure design more space of stepping down to make the structure of battery apron utmost point post welding frock more complicated, the production degree of difficulty is higher. In addition, because the sealing ring A3 is made of soft material, and the vertical output shaft, "Contraband" shaped connecting frame 110 and the pole a4 are not on the same axis, when the second transverse part 1102 is rotated to avoid the overlapped part, the gravity center is easy to be unstable, so that the situation of one-side inclination is easily caused, the inclination degree of the pole a4 relative to the battery cover plate body a1 is large, and the welding quality is influenced. In order to solve the problem of the skew pressure, more complicated and precise structures need to be designed to avoid the problem of the skew pressure as much as possible, but the problem cannot be solved well.
