Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 1-5 As shown, the embodiments of this utility model include:

[0019] A high-efficiency air-blowing screw fastening head includes a back plate 1, a Z-axis linear slide rail 2, an electric screwdriver bracket 3, a nozzle bracket 4, a lifting cylinder 5, and a secondary spring 6. The Z-axis linear slide rail 2 is mounted on the back plate 1, and two sliders 7 are mounted on the Z-axis linear slide rail 2. The electric screwdriver bracket 3 and the nozzle bracket 4 are uniformly mounted on the Z-axis linear slide rail 2 via the sliders 7. The lifting cylinder 5 is mounted at the top of the back plate 1, and the electric screwdriver bracket 3 is connected to the lower part of the lifting cylinder 5. The electric screwdriver bracket 3 and the nozzle bracket 4 are both externally mounted on the same side with an adapter block 8. A secondary spring 6 is arranged between the adapter blocks 8. The secondary spring 6 is used for stable pressing of the workpiece. An electric screwdriver head 9 is mounted on the electric screwdriver bracket 3, and a screw nozzle 10 is mounted on the nozzle bracket 4. The electric screwdriver head 9 and the screw nozzle 10 are coaxially matched.

[0020] The adapter block 8 is divided into a lower seat 81 and an upper seat 82. The lower seat 81 and the upper seat 82 are coaxially opened and movably connected to a guide post 11. The side of the lower seat 81 is provided with a set screw 12 for fixing the guide post 11. The secondary spring 6 is sleeved on the guide post 11, and the two ends of the secondary spring 6 are respectively abutted against the bottom surface of the lower seat 81 and the top surface of the upper seat 82.

[0021] Furthermore, a first lower limit bolt 13 is provided on the back plate 1, and a polyurethane elastomer is installed on the first lower limit bolt 13. The first lower limit bolt 13 is arranged at the lower end of the Z-axis linear slide rail 2 and is used to stop the slider 7.

[0022] Furthermore, a second lower limit bolt 14 is provided on the back plate 1, and a polyurethane elastomer is installed on the second lower limit bolt 14. The second lower limit bolt 14 is arranged directly below the adapter block 8 and is used to stop the adapter block 8.

[0023] Furthermore, a hydraulic buffer 15 is provided on the back plate 1, and the hydraulic buffer 15 faces upward directly towards the electric screwdriver bracket 3.

[0024] Furthermore, the lifting cylinder 5 is connected to a second guide rod 16, and the electric screwdriver bracket 3 has a through groove 17 with a through hole. The second guide rod 16 passes through the through hole, and the lower end of the second guide rod 16 is provided with a bolt 19 for synchronously driving the electric screwdriver bracket 3 to reset when the lifting cylinder 5 is lifted. The upper end of the second guide rod 16 is provided with an integrally formed neck 20, and a primary spring 21 is sleeved on the second guide rod 16. The primary spring 21 is housed in the through groove 17, with the upper end of the primary spring 21 abutting against the neck 20 and the lower end abutting against the through groove 17.

[0025] When the lifting cylinder 5 descends, the adapter block 8 compresses the spring, pressing the nozzle bracket 4 firmly against the workpiece surface. Based on the workpiece surface height, the nozzle can float and adapt under the spring force. The nozzle bracket 4 and the electric screwdriver bracket 3 are integrated on the same linear rail, achieving a non-interfering linkage effect. This makes the device simpler, more compact, and more efficient, effectively reducing maintenance and adjustment difficulties, and achieving cost reduction and efficiency improvement. As the lifting cylinder 5 continues to descend, the electric screwdriver head 9 pushes the bit into the nozzle and connects the screw, then screw fastening can begin. Throughout the entire process, the spring provides pressure support for the nozzle linkage, and the force transmission is uniformly established on the same linear rail, resulting in high efficiency. The spring force ensures that the lower end of the nozzle remains firmly against the workpiece surface, thus guaranteeing stability during screw fastening.

[0026] In summary, this utility model provides a high-efficiency air-blowing screw fastening head. By using a spring to unify the electric screwdriver head 9 and the nozzle on the same linear rail to achieve coordinated linkage, it optimizes the power transmission path and simplifies structural redundancy. This not only effectively improves fastening stability but also significantly improves the problems of mechanism redundancy and maintenance adjustment difficulty.
