Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a battery frame welding assembly for an electric vehicle. Background Art

[0002] The electric vehicle battery frame welding assembly is a clamping device for welding the electric vehicle battery frame. The electric vehicle battery frame welding assembly commonly used by enterprises realizes the clamping and fixing of the electric vehicle battery frame through the cooperation of multiple groups of clamping arms set up up, down, left and right. After the electric vehicle battery frame is clamped and fixed, mechanical operations such as welding, punching, and drilling are performed on the electric vehicle battery frame instead of welding alone.

[0003] When the electric vehicle battery frame is placed on a robotic arm and fixed, there is no structure to support the center of the electric vehicle battery frame. When the electric vehicle battery frame is subjected to mechanical operation, the suspended part away from the center of the clamping arm is compressed and deformed, which affects the quality of the finished product. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an electric vehicle battery frame welding assembly, which is used to solve the problem that when the electric vehicle battery frame is fixed with the electric vehicle battery frame welding assembly commonly used by enterprises, the suspended part at the center of the electric vehicle battery frame is compressed and deformed.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A welding assembly for an electric vehicle battery frame comprises a base, and a clamping arm located on the upper surface of the base for fixing the battery frame, wherein an XY-axis movable platform located directly below the battery frame is arranged on the upper surface of the base, a movable seat is slidably connected to a transverse sliding frame on the XY-axis movable platform, a support column is fixedly connected to the center position of the top of the movable seat, a connecting groove is movablely provided on the top sleeve of the support column, a plurality of lifting support rods are vertically arranged in the connecting groove, and a supporting spring located in the connecting groove is arranged at the bottom of each lifting support rod.

[0007] Preferably, the lifting support rod includes a connecting portion located at the bottom and fixedly connected to the top of the support spring, and a supporting portion located at the top of the connecting portion.

[0008] Preferably, the connecting portion and the supporting portion have the same shape.

[0009] Preferably, the support column is a support rod with a cross-shaped cross section.

[0010] Preferably, the length of the support spring is smaller than the depth of the connecting groove, and the length of the lifting support rod is twice the length of the support spring.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model provides a lifting support rod that can be moved just below the battery frame. The lifting support rod has a lifting function and can adapt to the shape of the position that needs to be supported on the lower surface of the battery frame, ensuring that the lifting support rod supports the battery frame. When the battery frame is subjected to mechanical operations such as welding and punching, the center position of the battery frame will not be completely suspended, thereby increasing the compressive resistance and reducing the deformation of the battery frame during processing. This solves the problem that when the electric vehicle battery frame welding assembly commonly used by enterprises fixes the electric vehicle battery frame, the suspended part of the center position of the electric vehicle battery frame is subjected to compressive deformation.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-3 As shown, the utility model provides a technical solution: an electric vehicle battery frame welding assembly, comprising a base 1, a clamping arm 2 located on the upper surface of the base 1 for fixing a battery frame 3;

[0019] An XY-axis moving platform 4 is arranged on the upper surface of the base 1 and is located directly below the battery frame 3. A moving seat 5 is slidably connected to the transverse sliding frame on the XY-axis moving platform 4. A support column 6 is fixedly connected to the center position of the top of the moving seat 5. The support column 6 is a support rod with a cross-shaped cross section, which ensures structural strength while saving raw materials. A connecting groove 7 is provided on the top of the support column 6. A plurality of lifting support rods 8 are vertically arranged in the connecting groove 7.

[0020] The lifting support rod 8 includes a connecting portion 801 located at the bottom and fixedly connected to the top of the support spring 9, and a supporting portion 802 located at the top of the connecting portion 801. The supporting portion 802 is soft rubber and is not easy to damage the lower surface of the battery frame 3 during support. The connecting portion 801 and the supporting portion 802 have the same shape. The lower surface of the battery frame 3 is supported by the contact between the supporting portion 802 and the lower surface of the battery frame 3 to ensure that the battery frame 3 is not completely suspended in the air. A supporting spring 9 located in the connecting groove 7 is provided at the bottom of each lifting support rod 8. The length of the supporting spring 9 is less than the depth of the connecting groove 7. The length of the lifting support rod 8 is twice the length of the supporting spring 9. The supporting spring 9 is located in the connecting groove 7 and will not pop out. The design of the length of the lifting support rod 8 can give the lifting support rod 8 a larger lifting space.

[0021] Working principle:

[0022] The battery frame 3 is fixed on the clamping arm 2 through the clamping arm 2. When the battery frame 3 is welded, the position of the movable seat 5 is adjusted according to the position on the battery frame 3 where welding is required. The XY axis movable platform 4 drives the movable seat 5 to move to below the position where the battery frame 3 needs to be welded. The lifting support rod 8 supports the lower surface of the battery frame 3 to prevent the battery frame 3 from being completely suspended. The lifting support rod 8 is pressed down and causes the support spring 9 to deform to adapt to the shape of the lower surface of the battery frame 3, thereby ensuring the supporting effect of the battery frame 3.
