Description

Technical Field

[0001] The utility model relates to a processing device for automobile parts, in particular to a welding fixture for a battery box of a new energy vehicle. Background Art

[0002] The battery pack of a new energy electric vehicle is its core component. The battery box in the battery pack plays a supporting and covering role. The battery box is assembled from a battery box frame and a battery box panel. The battery box is fixed to the vehicle chassis through the support ears on its frame.

[0003] The battery box frame is a rectangular structure with multiple lugs installed on each side. During production, the OEM requires that the outer lugs be welded to the designated locations on the battery box frame. When welding a small number of battery box frames, marking the welding locations can be done by hand-holding the lugs. However, when welding a large number of battery box frames, continuing to use marking and hand-holding methods is no longer sufficient to keep up with the production pace.

[0004] Therefore, it is necessary to design a corresponding fixture for the lug welding process of the battery box frame. Utility Model Content

[0005] The utility model provides a battery box frame outer ear welding fixture, the key of which is: comprising a support base, the support base is provided with a plurality of frame support seats, a plurality of frame inner side guides, and a plurality of ear clamping assemblies;

[0006] The support base is provided with a frame support area corresponding to the battery box frame, and multiple frame support seats are distributed along the frame support area. The inner frame guide is located on the inner side of the frame support area and close to the frame support area. The support ear clamping assembly is located on the outer side of the frame support area. The support ear clamping assembly is equipped with a retraction and extension power mechanism, and the retraction and extension power mechanism drives the support ear clamping assembly to approach or move away from the frame support area.

[0007] The frame support area corresponds to the outermost portion of the battery box frame and is used to accommodate this portion. The frame support seat lifts and supports the outermost portion of the battery box frame from below. Multiple inner frame guides cooperate to guide and position the outermost portion of the battery box frame from the inside, ensuring accurate placement of the battery box frame. The support ear clamping assembly corresponds to the designed position of the support ear and provides support for the support ear. BRIEF DESCRIPTION OF THE DRAWINGS
