The positioning tool is designed to improve assembly efficiency, ensure assembly accuracy, reduce manual errors, and ensure the correct alignment and electrical connection between the controller box and other components on the electric vehicle (such as batteries, motors, wiring harnesses, etc.).

[0003] When the existing electric vehicle control box is transported by the conveying device, when a single control box is clamped, the subsequently transported control boxes will continuously collide with the clamped control box, which will cause the clamped control box to be displaced and corrected, thereby reducing the accuracy of the control box during processing. In addition, the existing positioning work usually cooperates with bolts and positioning, and then the staff manually changes the clamping distance, which is time-consuming and labor-intensive, increases the workload of the staff, and is inconvenient to use. Therefore, we propose an electric vehicle controller box positioning fixture with easy-to-use functions, which is urgently needed to be developed. Utility Model Content

When the conveying device is used to transport the control box, when a single control box is clamped, the subsequently transported control boxes continuously collide with the clamped control box, thereby causing the clamped control box to be in the position of deviation, thereby reducing the accuracy of the control box during processing.

[0009] Preferably, the outer surface of the fixing plate is connected to two guide plates which are symmetrically arranged on the left and right sides, and the outer surface of the guide plate is slidably connected to a sliding block.

[0010] Preferably, a push rod is connected to the bottom of the sliding block, and an outer surface of the push rod is slidably connected to the push frame.

[0011] Preferably, the outer surface of the sliding block is connected to two symmetrically arranged first long rods, and one end of the first long rod away from the sliding block is connected to a clamping plate in contact with the top of the conveying device.

[0012] Preferably, the baffle assembly includes a round rod, the outer surfaces of the round rod and the rotating rod are connected to two meshing bevel gears, the left side of the fixed plate is connected to a plurality of welding plates, and the front side of the rear welding plate is sequentially penetrated by threaded rods.

[0013] Preferably, the outer surface of the threaded rod is threadedly connected with two threaded blocks that are symmetrically arranged front and back, and one side of the threaded block is slidably connected to the fixing plate.
