[0034] The working principle of the battery pack water cooling plate joint positioning fixture provided by the utility model is as follows:

[0035] When it is necessary to position the joint 3 above the connecting hole 101, first install the adjusting sleeve 4 on the jig body 2, and the jig body 2 is installed on the battery pack water cooling plate body 1. At this time, the metal pressure rod 6 can pass through the connecting block from above the connecting block 5, and the positioning shaft 7 passes through the joint 3 and extends into the connecting hole 101. The bottom of the metal pressure rod 6 presses down the joint 3 through the gravity of the metal pressure rod 6 itself to position the joint 3.

[0036] Compared with the related art, the battery pack water cooling plate joint positioning fixture provided by the utility model has the following beneficial effects:

[0037] The utility model installs the jig on the battery pack water-cooling plate body 1 through the original installation hole 102 on the battery pack water-cooling plate body 1, and then the positioning shaft 7 passes through the joint 3 and extends into the connecting hole 101. The metal pressure rod 6 presses down the top of the joint 3 from above, quickly aligns the joint 3 with the connecting hole 101, and positions the joint 3 above the connecting hole 101, so that there is no need to manually straighten the joint 3 during the welding process, and the welding position on the joint surface will not be blocked, which effectively improves the welding accuracy and welding speed.

[0038] Embodiment 2

[0039] The adjusting sleeve 4 has an annular groove 12 in which a positioning spring 13 is fixedly connected. One end of the positioning spring 13 is fixedly connected to a positioning bead 14 . A positioning arc groove 15 used in conjunction with the positioning bead 14 is formed on one side of the metal pressure rod 6 .

[0040] A positioning protrusion 16 is fixedly connected in the annular groove 12 , and the positioning protrusion 16 is used to limit the movement of the positioning bead 14 .

[0041] like Figure 5 and Figure 6 The positioning protrusion 16 restricts the movement of the positioning bead 14 so that more than half of the positioning bead 14 cannot move to the outside of the annular groove 12 .

[0042] A rectangular plate 17 is fixedly connected to one side of the metal pressure rod 6 , and the rectangular plate 17 is slidably connected to the connecting block 5 .

[0043] like Figure 5 and Figure 6 There is an opening on the connecting block 5 corresponding to the rectangular plate 17 to realize the sliding connection between the rectangular plate 17 and the connecting block 5, and to limit the metal pressure rod 6 so that the positioning arc groove 15 on one side of the metal pressure rod 6 is aligned in the direction of the annular groove 12.

[0044] The working principle of the battery pack water cooling plate joint positioning fixture provided by the utility model is as follows:

[0045] When the metal pressure rod 6 passes through the connecting block 5, the bottom of the metal pressure rod 6 will squeeze the arc surface of the positioning bead 14, and press the positioning bead 14 into the annular groove 12. When the metal pressure rod 6 is pressed above the joint 3, the positioning arc groove 15 and the annular groove 12 are aligned, and the positioning spring 13 stretches to push the positioning bead 14, and the positioning bead 14 is pressed against the inner wall of the positioning arc groove 15, providing elastic positioning for the metal pressure rod 6;

[0046] When the metal pressure rod 5 is pulled upward, the arc surface of the inner wall of the positioning arc groove 15 squeezes the arc surface of the positioning bead 14, so that the positioning bead 14 is pressed into the annular groove 12 again without affecting the up and down movement of the metal pressure rod 5.

[0047] Compared with the related art, the battery pack water cooling plate joint positioning fixture provided by the utility model has the following beneficial effects:

[0048] The utility model pushes the positioning bead 14 through the positioning spring 13, and presses the positioning bead 14 into the positioning arc groove 15, which can improve the positioning ability of the metal pressure rod 6, so that the metal pressure rod 6 can provide a more stable positioning ability for the joint 3, and at the same time does not affect the up and down movement of the metal pressure rod 6.

[0049] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
