Specific implementation mode
Specific embodiment of the present utility model and operation principle are described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to 4, a kind of battery tray side bar precision welding tooling, including pedestal 1, including pedestal 1, the bottom
Multigroup side position-limit mechanism 3 is fixed with by the first backing plate 2 on seat 1, to battery tray when multigroup side position-limit mechanism 3 is used to weld
Disk side bar carries out limit and along the circumferentially distributed of the pedestal 1, is also fixed with by the second backing plate 4 on the pedestal 1 more
Group and 3 matched feeding pressure mechanism 5 of the side position-limit mechanism, and the feeding pressure mechanism 5 in welding with battery tray side bar
Upper surface is in close contact, and end face position-limit mechanism 6 is also respectively fixed in the front and rear sides of the pedestal 1, is located at two before and after pedestal 1
The end face position-limit mechanism 6 of side is oppositely arranged, and both sides of the face position-limit mechanism 6 and the central point of the side position-limit mechanism 3 are located at
On same straight line.
