Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, and more specifically, to an adjustable fixture for manufacturing new energy vehicle batteries. Background Technique

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and driving, and form vehicles with advanced technical principles, new technologies, and new structures. Unconventional vehicle fuels refer to fuels other than gasoline and diesel. During the production of the battery box of an electric vehicle, different components need to be welded on both the front and back sides, and fixtures are required to support and fix it during the welding process.

[0003] After retrieval, the utility model patent with the publication number CN218051119U discloses a fixture for a new energy vehicle battery box. The key points of its technical solution are: including a fixed plate and support plates vertically arranged on opposite sides of the top of the fixed plate. A placement rack for placing the battery box is vertically slidably connected between the two support plates through a pushing member. When the pushing member drives the placement rack to move vertically downward, a rotating member for driving the battery box to rotate is provided above the placement rack between the two support plates.

[0004] However, the above patent still has the following deficiencies: Although the placement rack can drive the battery box to move up and down and support the battery box at the same time, there may be protrusions on both the front and back sides of the battery box due to special requirements. Also, after welding equipment on both the front and back sides of the battery box, it will become uneven, which is not convenient to ensure that the battery box is stably placed horizontally on the placement rack. In addition, when the battery box is placed on the placement rack, it cannot be guaranteed that the position where the battery box is placed can be clamped and fixed by the baffle and the moving plate. Therefore, we propose an adjustable fixture for manufacturing new energy vehicle batteries. Content of the Utility Model

In addition, start the third motor 18 to drive the third lead screw 17 to rotate, and through the threaded fit between the third lead screw 17 and the front - rear moving seat 19, drive the front - rear moving seat 19 and the battery box to move back and forth, so as to move the battery box placed above the support columns 10 to a suitable position. Finally, start the second electric push rod 22 to drive the telescopic box 23 and the U - shaped frame 26 to move horizontally, so that both ends of the battery box are respectively clamped into the inner sides of the two U - shaped frames 26. Start the fourth motor 29 to drive the bidirectional lead screw 27 to rotate, and use the threaded fit between the bidirectional lead screw 27 and the clamping plate 28 to drive the two clamping plates 28 to approach each other, and use the clamping plates 28 to clamp and fix the side of the battery box. At this time, weld the front of the battery box. When the front of the battery box is welded, lower the placement rack 8 and the support columns 10 to a suitable height, start the fifth motor 25 to drive the U - shaped frame 26 and the battery box to rotate, so as to turn the back of the battery box upward for welding the back of the battery box, and that's it.
