During the welding process of the battery tray, an inward shrinking phenomenon will occur. The current welding tooling cannot effectively prevent the inward shrinking of the battery tray, and thus cannot effectively control the perpendicularity of the battery tray, affecting the welding quality of the battery tray. Summary of the Utility Model

Detailed description of the specific implementation

[0038] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0039] Next, in conjunction with Figures 1 to 8 The welding tooling 200 and the welding station 1000 according to the embodiments of the present utility model will be described.

[0040] As Figures 1 to 4 shown, the welding tooling 200 according to the embodiment of the present utility model is suitable for clamping and fixing workpieces to be welded such as battery trays for welding. The welding tooling 200 includes a base 21 and a dead point internal support mechanism 22. The dead point internal support mechanism 22 includes an internal support mounting part 221, a driving unit 222, a hinge unit 223, a sliding unit 224 and a limiting unit 225.

[0041] Specifically, the internal support mounting part 221 is fixed on the base 21, and the internal support mounting part 221 is mainly used for mounting functional components such as the driving unit 222, the hinge unit 223, the sliding unit 224 and the limiting unit 225.

[0042] The driving unit 222 is arranged on the inner support mounting part 221 and mainly provides power for the dead point inner support mechanism 22. The driving unit 222 can be a cylinder but is not limited to a cylinder.

[0043] The hinge unit 223 is pivotally connected to the inner support mounting part 221, the driving unit 222 and the sliding unit 224 respectively. The sliding unit 224 is arranged on the inner support mounting part 221 in a linearly slidable manner, so that the driving unit 222 drives the hinge unit 223 to rotate, and the rotating hinge unit 223 drives the sliding unit 224 to perform a linear motion along the inner support mounting part 221 between the first position and the second position; when the sliding unit 224 is in the first position, the sliding unit 224 is away from the inner side wall of the frame of the workpiece to be welded and does not abut against the workpiece to be welded; when the sliding unit 224 is in the second position, the sliding unit 224 abuts against the inner side wall of the frame of the workpiece to be welded, realizing the dead point inner support function of the dead point inner support mechanism 22, preventing the workpiece to be welded from shrinking inward during the welding process, and effectively controlling the perpendicularity of the workpiece to be welded, which is beneficial to improving the welding quality of the workpiece to be welded.

[0044] The limiting unit 225 is arranged on the inner support mounting part 221 and is used to adjust the limiting position of the hinge unit 223 and limit the hinge unit 223. It can be understood that the main function of the limiting unit 225 is to limit the hinge unit 223. Only when the hinge unit 223 is in the precise limiting position can the sliding unit 224 be precisely in the second position and abut against the inner side wall of the frame of the workpiece to be welded, realizing the dead point inner support function of the dead point inner support mechanism 22, preventing the workpiece to be welded from shrinking inward during the welding process, and effectively controlling the perpendicularity of the workpiece to be welded, ensuring the welding quality of the workpiece to be welded. Since the limiting unit 225 can adjust the limiting position of the hinge unit 223 to make the hinge unit 223 in the precise limiting position, the dead point inner support mechanism 22 can effectively control the perpendicularity of the workpiece to be welded and effectively improve the welding quality of the workpiece to be welded.

[0045] The driving unit 222 drives the sliding unit 224 to perform a linear motion by driving the hinge unit 223. When the hinge unit 223 abuts against the limiting unit 225 at the limiting position and is locked, the sliding unit 224 adaptively abuts against the inner side wall of the frame of the workpiece to be welded.

[0046] During use, in order to effectively prevent the workpiece to be welded from shrinking inward during the welding process, effectively control the perpendicularity of the workpiece to be welded, and effectively improve the welding quality of the workpiece to be welded, the position of the limiting part of the limiting unit 225 that abuts against the hinge unit 223 is adjusted through the limiting unit 225. For example, as Figure 2 and Figure 4The limiting unit 225 therein can be adjusted up and down by itself, that is, the limiting position of the hinge unit 223 can be adjusted, so that the hinge unit 223 is in an accurate limiting position. Then, the hinge unit 223 is driven by the driving unit 222 to the adjusted limiting position. At this time, the hinge unit 223 abuts against the limiting portion of the limiting unit 225. In this way, the hinge unit 223 is locked under the cooperation of the driving unit 222 and the limiting unit 225. At this time, the sliding unit 224 tightly abuts against the inner side wall of the frame of the workpiece to be welded, thereby effectively controlling the perpendicularity of the workpiece to be welded and effectively improving the welding quality of the workpiece to be welded.

[0047] According to the welding tooling 200 of the embodiment of the present invention, by adjusting the limiting position of the hinge unit 223 through the limiting unit 225, the limiting position of the hinge unit 223 can be made accurate, effectively controlling the perpendicularity of the workpiece to be welded and effectively improving the welding quality of the workpiece to be welded.

[0048] In some embodiments, as Figure 2 and Figure 4 shown, the hinge unit 223 includes a first rotating block 2231 and a second rotating block 2232; the first rotating block 2231 is pivotally connected to the inner support mounting portion 221, the driving unit 222 and the second rotating block 2232 respectively, and the second rotating block 2232 is pivotally connected to the sliding unit 224. When the driving unit 222 drives the first rotating block 2231 to rotate and swing around the pivot axis between the first rotating block 2231 and the inner support mounting portion 221, it can drive the pivot axis between the first rotating block 2231 and the second rotating block 2232 to swing up and down around the pivot axis between the first rotating block 2231 and the inner support mounting portion 221, thereby driving the sliding unit 224 to move linearly between the first position and the second position on the inner support mounting portion 221. The limiting position is defined as: the pivot axis position between the first rotating block 2231 and the inner support mounting portion 221, the pivot axis position between the first rotating block 2231 and the second rotating block 2232, and the pivot axis position between the second rotating block 2232 and the sliding unit 224 are on the same horizontal straight line to realize the dead point inner support function of the dead point inner support mechanism 22.

[0049] In some embodiments, the pivot connection between the first rotating block 2231 and the driving unit 222 is located above the pivot connection between the first rotating block 2231 and the second rotating block 2232. The limiting unit 225 is arranged below the first rotating block 2231 and near the pivot connection between the first rotating block 2231 and the second rotating block 2232, and the limiting unit 225 can be adjusted in a lifting manner. By adjusting the lifting of the limiting unit 225, the limiting position of the first rotating block 2231 can be adjusted, so that the pivot axis position between the first rotating block 2231 and the inner support mounting part 221, the pivot axis position between the first rotating block 2231 and the second rotating block 2232 during pivoting, and the pivot axis position between the second rotating block 2232 and the sliding unit 224 are on the same horizontal straight line, which is convenient for adjustment.

[0050] It should be noted that when the limiting unit 225 is replaced by other limiting members that cannot be adjusted in a lifting manner by themselves, due to the machining errors in the sizes of other limiting members, the limiting position of the hinge unit 223 will be inaccurate, which will further affect that the sliding unit 224 cannot abut against the inner side wall of the frame of the workpiece to be welded, and it cannot prevent the workpiece to be welded from shrinking inward well during the welding process, and further cannot control the perpendicularity of the workpiece to be welded well, affecting the welding quality of the workpiece to be welded.

[0051] In some embodiments, as Figure 4 shown, the limiting unit 225 is a stud, and the lower end of the stud is threadedly connected to the inner support mounting part 221. In this way, by adjusting the height of the stud protruding upward from the inner support mounting part 221, the limiting position of the first rotating block 2231 can be adjusted, so that the pivot axis position between the first rotating block 2231 and the inner support mounting part 221, the pivot axis position between the first rotating block 2231 and the second rotating block 2232 during pivoting, and the pivot axis position between the second rotating block 2232 and the sliding unit 224 are on the same horizontal straight line, which is very convenient for adjustment.

[0052] In some embodiments, the sliding unit 224 includes a slider 2241 and a top block assembly 2242. The slider 2241 is in linear sliding fit with the inner support mounting part 221, and the top block assembly 2242 is fixed on the slider 2241. The top block assembly 2242 is used to abut against the inner side wall of the frame of the workpiece to be welded adaptively to prevent the workpiece to be welded from shrinking and deforming inward.

[0053] In some embodiments, the top block assembly 2242 includes a first top block 22421 and a second top block 22422; the first top block 22421 and the second top block 22422 are located on the same side of the slider 2241, and the first top block 22421 and the second top block 22422 are arranged at intervals in the vertical direction, so that the lateral pushing area against the workpiece to be welded can be increased to prevent the workpiece to be welded from shrinking and deforming inward.

[0054] In some embodiments, the first top block 22421 has a first abutting surface, which is a vertical plane and is used to abut against the vertical surface of the inner side wall of the workpiece to be welded; the second top block 22422 has a second abutting surface, which is a ramp surface. The second abutting surface protrudes from the first abutting surface as a whole and is used to abut against the inclined surface of the inner side wall of the workpiece to be welded, so as to increase the lateral pushing area of the workpiece to be welded and prevent the workpiece to be welded from shrinking and deforming.

[0055] In some embodiments, the dead point internal bracing mechanisms 22 are distributed around the periphery of the base 21, that is, the dead point internal bracing mechanisms 22 are symmetrically or asymmetrically distributed at two sets of opposite sides of the base 21. Specifically, the same or different numbers of dead point internal bracing mechanisms 22 are provided at the opposite sides of the long sides of the base 21, and among the opposite sides of the long sides of the base 21, the dead point internal bracing mechanisms 22 at one side are symmetric or asymmetric with respect to the dead point internal bracing mechanisms 22 at the other side; the same or different numbers of dead point internal bracing mechanisms 22 are provided at the opposite sides of the short sides of the base 21, and among the opposite sides of the short sides of the base 21, the dead point internal bracing mechanisms 22 at one side are symmetric or asymmetric with respect to the dead point internal bracing mechanisms 22 at the other side. In this way, by arranging the dead point internal bracing mechanisms 22 around the periphery of the base 21, the inner side wall of the frame of the workpiece to be welded can be extruded outward in the circumferential direction, avoiding the inward shrinkage of the workpiece to be welded during the welding process and preventing the workpiece to be welded from shrinking and deforming.

[0056] In some embodiments, as Figure 1 、 Figures 5 to 7 shown, a heating unit 23 is further included. The heating unit 23 is arranged on the base 21 and is used to heat the workpiece to be welded, which can effectively control the flatness of the workpiece to be welded and is beneficial to improving the welding quality.

[0057] In some embodiments, the heating unit 23 includes a support plate 231, a heat insulation plate 232 and a heating plate 233. The support plate 231 is installed on the base 21 and can fix the heating unit 23 on the base 21. The support plate 231, the heat insulation plate 232 and the heating plate 233 are stacked in sequence. Among them, the support plate 231 can be a metal plate, such as an iron plate, and can reliably support the heat insulation plate 232; the heating plate 233 is used to generate heat, has a large heating area, heats the workpiece to be welded evenly, can prevent the workpiece to be welded from deforming, effectively controls the flatness of the workpiece to be welded, and is beneficial to improving the welding quality. The heat insulation plate 232 can effectively prevent the heat generated by the heating plate 233 from being transmitted downward, so that the heat is transmitted upward to the workpiece to be welded as much as possible.

[0058] In some embodiments, the heat insulation plate 232 is a mica plate, and the mica plate has a good heat insulation effect.

[0059] In some embodiments, the heating plate 233 includes an electric heating element (not shown in the figure) and a rubber plate. The electric heating element is a heating element such as an electric heating wire, and the electric heating elements are distributed within the rubber plate. The rubber plate plays a role in protecting and insulating the electric heating element, and at the same time can make the heat distribution uniform. Preferably, the rubber plate can be a silica gel plate.

[0060] In some embodiments, the heating unit 23 further includes a heat conducting plate 234. The heat conducting plate 234 covers the heating plate 233, plays a protective role for the heating plate 233, and at the same time can preferably transfer the heat evenly to the workpiece to be welded. Preferably, the heat conducting plate 234 is a metal plate, such as an aluminum plate, etc.

[0061] In some embodiments, a magnetic unit 24 is further included. The magnetic unit 24 is distributed around the periphery of the base 21 and is used to tightly attract the pressing plate placed on the workpiece to be welded, which is beneficial to improving the welding quality of the workpiece to be welded.

[0062] In some embodiments, a pressing mechanism 25 is further included. The pressing mechanism 25 is distributed around the periphery of the base 21 and is used to press the workpiece to be welded and ensure the overall flatness of the frame of the workpiece to be welded.

[0063] As Figures 1 to 8 shown, the present utility model also proposes a welding station 1000.

[0064] The welding station 1000 according to the embodiment of the present utility model includes the welding tooling 200 of the embodiment of the present utility model.

[0065] Since the welding station 1000 of the embodiment of the present utility model adopts the welding tooling 200 of the embodiment of the present utility model, it has the same advantages as the welding tooling 200 of the embodiment of the present utility model, which will not be elaborated here.
