The automated production press-fitting tool for automobile parts is provided with an adjustment mechanism, and the adjustment mechanism is arranged in the automated production press-fitting tool for automobile parts. Through the mutual cooperation between the various structures in the adjustment mechanism, the first threaded rod is rotated by setting a driving motor, a rotating rod, a first bevel gear and a second bevel gear, and then the upward movement of the threaded barrel is achieved. Through the upward and downward movement of the threaded barrel, the upward and downward movement of the positioning box is achieved, and finally the height adjustment of the press-fitting position is achieved, so that the press-fitting tool can press-fit the center position of the automobile parts, and the tool can adapt to automobile parts of various sizes.

Since the fixing rod 9 is threadedly connected to the placement plate 8, the bottom of the fixing rod 9 is against the top of the workpiece, so that the workpiece is clamped and positioned. When different surfaces of the workpiece need to be processed, the staff starts the motor 5 to drive the rotating shaft 6 to rotate, and then the rotating shaft 6 drives the placement plate 8 to rotate, and then the placement plate 8 drives the workpiece to flip.

The staff starts the motor 13 to drive the forward and reverse screw rod 14 to rotate, and two movable blocks 15 are symmetrically provided on the forward and reverse screw rod 14, and the movable blocks 15 are threadedly connected to the forward and reverse screw rod 14. Since the forward and reverse screw rod 14 and the movable blocks 15 are threadedly connected, the two movable blocks 15 move toward each other, and a connecting rod 16 is provided on the top of the movable block 15, and the connecting rod 16 It is welded with the moving block 15, and the connecting rod 16 extends out of the bottom plate 1.

Since the fixing rod 9 and the placement plate 8 are threadedly connected, the bottom of the fixing rod 9 is against the top of the workpiece to clamp and position the workpiece. When it is necessary to process different surfaces of the workpiece, the staff starts the motor 5 to drive the rotating shaft 6 to rotate, and then the rotating shaft 6 drives the placement plate 8 to rotate, and then the placement plate 8 drives the workpiece to flip. During the flipping of the workpiece, the driven shaft 7 is driven to rotate accordingly, thereby ensuring that the workpiece is smoothly flipped to the appropriate angle. This is the working principle of the workpiece machining positioning tooling.
