[0024] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0025] The following is in conjunction with the appendix Figure 1-9This application provides a detailed description of a cylinder head tightening moving mechanism, comprising a lateral moving mechanism 1, a longitudinal moving mechanism 2, a first slide rail 3, and a support frame 4. The lateral moving mechanism 1 and the first slide rail 3 are both mounted on the support frame 4, and the longitudinal moving mechanism 2 is mounted on the first slide rail 3. The lateral moving mechanism 1 and the longitudinal moving mechanism 2 are connected. Through the combination of the lateral moving mechanism 1 and the longitudinal moving mechanism 2, the tightening gun can move in a two-dimensional plane, adapting to the tightening requirements of different cylinder head models and improving the versatility and flexibility of the equipment.

[0026] Furthermore, the lateral movement mechanism 1 includes a first drive motor 5, a fixed beam 6, a first lead screw 7, a first lead screw assembly 8, and a first connecting block 9. The fixed beam 6 is fixed to the support frame 4 via a mounting plate 10. The first drive motor 5 is mounted at one end of the fixed beam 6, and the output end of the first drive motor 5 is fixed to the first lead screw 7. The first lead screw assembly 8 is fitted onto the first lead screw 7 and fixed to the first connecting block 9. The lateral movement mechanism 1 uses lead screw transmission, which features high transmission accuracy and good stability, ensuring precise position control of the tightening gun in the lateral direction, thereby improving tightening accuracy.

[0027] Furthermore, the bottom of the fixed beam 6 is provided with a groove 11 for the first connecting block 9 to pass through. The groove 11 at the bottom of the fixed beam 6 provides a moving path for the first connecting block 9, while ensuring the stability of the first connecting block 9's movement, making the lateral movement smoother.

[0028] Furthermore, the longitudinal movement mechanism 2 includes a first slider 12, a first slide plate 13, a drive cylinder 14, a second slide rail 15, a second slider 16, and a second slide plate 17. The first slider 12 is slidably connected to the first slide rail 3, and the first slide plate 13 is connected to the first slider 12. The drive cylinder 14 and the second slide rail 15 are both mounted on the first slide plate 13. The output end of the drive cylinder 14 is fixedly connected to a second connecting block 18. The second slide plate 17 is mounted on the second slide rail 15 via the second slider 16. The longitudinal movement mechanism 2 is driven by the drive cylinder 14, which has a fast response speed and can quickly adjust the longitudinal position of the tightening gun, improving production efficiency. The cooperation between the second slide rail 15 and the second slider ensures the stability of the longitudinal movement.

[0029] Furthermore, the first connecting block 9 is connected to the second connecting block 18 via a reinforcing plate 19. The connection between the first connecting block 9 and the second connecting block 18 via the reinforcing plate 19 enhances the connection strength between the lateral moving mechanism 1 and the longitudinal moving mechanism 2, thereby improving the stability and reliability of the entire mechanism.

[0030] Furthermore, limit stops 20 are provided at both ends of the second slide rail 15 on the second slide plate 17, and each limit stop 20 is equipped with a proximity switch 21. The limit stops 20 and proximity switches 21 at both ends of the second slide rail 15 effectively prevent excessive movement of the second slide plate 17, avoiding equipment damage and ensuring the safety and reliability of the equipment. The proximity switches 21 also enable automated control and improve production efficiency.

[0031] Furthermore, the second slide plate 17 is provided with several mounting holes 22 for installing tightening guns. The multiple mounting holes 22 on the second slide plate 17 facilitate the installation of tightening guns of different specifications, further improving the adaptability of the equipment and enabling it to meet the tightening requirements of different cylinder head models.

[0032] The beneficial effects of this utility model are as follows: This utility model is equipped with a transverse moving mechanism 1 and a longitudinal moving mechanism 2, which realizes the precise movement of the tightening gun 23 in a two-dimensional plane, can adapt to the tightening requirements of different cylinder head models, and improves the versatility and flexibility of the equipment; the transverse moving mechanism 1 adopts a screw drive, which has the characteristics of high transmission accuracy and good stability, and can ensure the precise position control of the tightening gun in the transverse direction; the longitudinal moving mechanism 2 is driven by a drive cylinder 14, which has a fast response speed and can quickly adjust the longitudinal position of the tightening gun, improving production efficiency; limit stops 20 and proximity switches 21 are set at both ends of the second slide rail 15, which can effectively prevent the second slide plate 17 from moving excessively, ensuring the safety and reliability of the equipment; multiple mounting holes 22 are set on the second slide plate 17, which facilitates the installation of tightening guns of different specifications, further improving the adaptability of the equipment.

[0033] Working principle: In use, the tightening gun 23 is installed on the mounting hole 22 of the second slide plate 17. The first drive motor 5 drives the first lead screw 7 to rotate, and the first lead screw pair 8 moves on the first lead screw 7, thereby driving the first connecting block 9 to slide in the slide groove, realizing the lateral movement of the longitudinal moving mechanism 2. The drive cylinder 14 drives the second connecting block 18 to move, thereby driving the second slide plate 17 to slide on the second slide rail 15, realizing the longitudinal movement of the tightening gun. The proximity switch 21 and the limit stop 20 can prevent the second slide plate 17 from moving excessively, ensuring the safe operation of the equipment.
