Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing technology, specifically a welding fixture for a new energy battery frame. Background Technology
[0002] During the layered welding process of new energy battery frames, traditional welding fixtures can only constrain the bottom layer of the frame, lacking rigid restraint on the sides and adjacent surfaces, resulting in significant deviations in position and perpendicularity after assembly. This problem further propagates to the battery installation stage, causing misalignment of mounting holes and forcing rework on-site by enlarging holes or adjusting the battery pack position, severely restricting the production line cycle time. Utility Model Content

Through improvements to the welding fixture, the manpower and efficiency during the assembly of each layer of the frame are effectively reduced. The positional accuracy of the holes in each layer of the assembled frame, as well as the flatness and perpendicularity of the rectangular tubes, are improved, resulting in more stable dimensions. This enhances efficiency for customers during battery installation and ensures higher product quality.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a welding fixture for a new energy battery frame, including a base plate, on which a plurality of positioning plates for positioning and supporting the new energy battery frame are provided. A side limiting device is provided on one short side of the base plate for limiting the positioning of each layer of the new energy battery frame. The side limiting device includes two opposing first limiting plates, the inner side of which is a first limiting edge. The upper ends of the two first limiting plates are connected by an upper limiting plate, and the lower ends of the two first limiting plates are connected by a lower limiting plate. The upper limiting plate, the lower limiting plate, and the two first limiting edges are located in the same vertical plane.

[0009] A further improvement is that an upper reinforcing rod is provided on the outer side of the upper limit plate, and a lower reinforcing rod is provided on the outer side of the lower limit plate.
[0010] A further improvement is that the first limiting plate is in the shape of a right trapezoid, and the lower end of the first limiting plate extends inward to form an extension, and the upper end of the extension is provided with a first limiting slot.
[0011] A further improvement is that: a first limiting horizontal plate is provided on the first limiting edge of one of the first limiting vertical plates, and the limiting horizontal plate is provided with a third limiting hole.
[0012] A further improvement is that an auxiliary limiting device is provided on one of the long sides of the base plate near the side limiting device. The auxiliary limiting device includes a second limiting upright plate, the inner side of which is a second limiting side, and a second limiting horizontal plate is provided on the inner side of which is near the lower end.
