This invention features six limiting grooves inside the limiting box for precise positioning of the first part. Simultaneously, the fourth hydraulic telescopic rod applies a stable thrust from the side, ensuring coaxial alignment of the first and third parts and preventing issues such as valve core misalignment and interface misalignment. The first and second vacuum suction cups employ a negative pressure adsorption design, which not only stably grips the parts but also prevents damage to the part surface caused by mechanical clamping. Furthermore, the suction cup positions precisely correspond to the limiting grooves and the part assembly positions, ensuring consistent positioning of the first, second, and third parts during assembly. This structural design significantly improves product performance stability and reduces quality issues such as nozzle leakage and poor atomization caused by assembly errors.

The first hydraulic telescopic rod 7 extends and pushes the first dovetail slider 6 to slide along the first guide rail 5, so that the gripper 8 moves to the third part 30. The gripper 8 clamps the third part 30 through the slot. The first dovetail slider 6 slides in the opposite direction and transfers the third part 30 to the preset assembly station on the first conveyor table 3. Finally, the fourth hydraulic telescopic rod 26 is activated to extend and push the first part 28 from the side of the limiting groove 32 to ensure that the first part 28 and the third part 30 are coaxially aligned to avoid assembly misalignment. After pressing, the second vacuum suction cup 22 releases the negative pressure and resets to the position to be gripped.
