[0029] This embodiment provides a camshaft cover multi-axis tightening machine. Figure 1 As shown, during the production process of the engine cylinder head, the camshaft cover 2 needs to be installed on the cylinder head 1 and locked by screws. The tightening machine of this embodiment is mainly used to tighten the installed screws.

[0030] As shown in the reference figure, the tightening main machine mainly includes a tightening main frame 3, which is used for the main support. A main lifting drive assembly is arranged on the tightening main frame 3, and the main lifting drive assembly is connected to the main lifting frame body 4. The main lifting drive assembly adopts a motor-driven method, which mainly includes a main lifting drive motor 6. The main lifting drive motor 6 drives the main lifting frame body 4 to move up and down through a screw nut and a guide rail slider, thereby realizing the lifting control of the main body of the 6-axis tightening machine in this embodiment, so that the corresponding tightening head enters a suitable working position.

[0031] In this embodiment, a main left-right displacement drive assembly is arranged on the main lifting frame body 4, and the main left-right displacement drive assembly is connected to the main left-right displacement mounting plate 5. In this embodiment, the main left-right displacement mounting plate 5 can switch the workstation in the left-right direction. Since each camshaft cover 2 has two left-right arranged screws, the main left-right displacement mounting plate 5 can be displaced to tighten the screws on the other side after tightening the screws on one side. The main left-right displacement drive assembly is mainly used to realize the switching of two workstations. It is controlled by a cylinder and mainly includes a main left-right displacement drive cylinder 7. The main left-right displacement drive cylinder 7 cooperates with the guide rail slider to drive the main left-right displacement mounting plate 5 to realize the switching of the left-right workstation.

[0032] In this embodiment, three groups of six tightening heads are arranged on the main left and right displacement mounting plate 5. Specifically, a front front and rear displacement drive assembly, a middle front and rear displacement drive member and a rear front and rear displacement drive assembly are arranged on the main left and right displacement mounting plate 5. The front front and rear displacement drive assembly is connected to the front tightening assembly 10. The front tightening assembly 10 includes two tightening heads 16 that can adjust the position left and right.

The rear front and rear displacement drive assembly can drive the two tightening heads 16 on the rear side to adjust and shift synchronously forward and backward. By changing the position, the tightening head 16 can enter different working positions, so as to tighten the screws at different positions.

[0033] In this embodiment, the front front-to-back displacement drive assembly, the middle front-to-back displacement drive assembly, and the rear front-to-back displacement drive assembly are all driven by cylinders. The front front-to-back displacement drive assembly includes a front front-to-back displacement drive cylinder 13, which cooperates with the guide rail slider to drive the front tightening assembly 10 to move forward and backward to adjust the position, and sets a bolt on the limit block for positioning. The extension length of the positioning cylinder is adjusted by adjusting the length of the bolt on the limit block to shift it to the set position. Similarly, the middle front-to-back displacement drive assembly includes a middle front-to-back displacement drive cylinder 12, which cooperates with the guide rail slider to drive the middle tightening assembly 9 to move forward and backward. The rear front-to-back displacement drive assembly includes a rear front-to-back displacement drive cylinder 11, which cooperates with the guide rail slider to drive the rear tightening assembly 8 to move forward and backward. Each tightening assembly can be controlled individually by an independent cylinder. As shown in the reference figure, in this embodiment, the front tightening assembly 10, the middle tightening assembly 9 and the rear tightening assembly 8 share the guide rails installed on the main left and right displacement mounting plate 5 to achieve front and rear adjustment, so as to make the structure more compact.

[0034] In a preferred solution provided in the present embodiment, the spacing between the two tightening heads 16 corresponding to the front tightening assembly 10 and the rear tightening assembly 8 in the left and right directions can also be adjusted separately. Specifically, the front tightening assembly 10 also includes two front left and right position shifting drive motors 15, and the two front left and right position shifting drive motors 15 respectively drive the corresponding tightening heads 16 to move left and right through the screw nuts. Similarly, the rear tightening assembly 8 includes two rear left and right position shifting drive motors 14, and the two rear left and right position shifting drive motors 14 respectively drive the corresponding tightening heads 16 to move left and right through the screw nuts to realize the adjustment of the spacing between the tightening heads 16, making it more applicable.

[0035] As shown in the reference figure, openings for tightening heads 16 to pass through are provided on the main lifting frame body 4 and the main left and right displacement mounting plate 5. The six tightening heads 16 face downward and tighten the screws by rotating.
