[0022] A method for controlling an electric turning frame for welding a drive axle of a new energy vehicle, comprising:

[0023] Step 1: The entire device is moved to the installation position of the new energy vehicle drive axle, so that the new energy vehicle drive axle is located in the installation station, and the installation table is driven by the electric slide rail to slide horizontally along the moving groove. When the installation table and the components thereon move horizontally, until the clamping table, the rotating block and the two clamping rods are located above the new energy vehicle drive axle;

Since the vertical flip is performed after automatic clamping, the new energy vehicle drive axle can be automatically locked during welding, thereby avoiding the drive axle from being completely fixed during vertical flipping, thereby improving safety.

[0029] The rotating motor drives the two rotating gears to rotate, thereby driving the rotating block, the main body of the electric hoist and the new energy vehicle drive axle below it to rotate horizontally, adjusting the horizontal installation angle of the new energy vehicle drive axle, thereby facilitating the installation and fixation of the new energy vehicle drive axle; and the telescopic end of the main body of the electric hoist is controlled by a single chain, so that the position of the new energy vehicle drive axle can be finely adjusted at any time under human control during welding and installation, which is convenient for the installation of the new energy vehicle drive axle

[0030] The driving motor continues to drive the rotating gear to rotate. Since the two clamping rods are locked with each other through the arc head and the concave head, and the locking blocks 2 on the two clamping rods are respectively locked with the two locking blocks 1, the two clamping rods and the rotating block are locked with each other, causing the rotating gear to drive the rotating block to rotate vertically, thereby driving the new energy vehicle drive axle in the rotating block to rotate vertically to adjust the vertical installation angle of the new energy vehicle drive axle. The driving motor controls the clamping and vertical installation angle adjustment of the new energy vehicle drive axle, simplifies the driving equipment, and facilitates control.
