[0023] The present utility model will be further described below by way of embodiments, but the present utility model is not limited to the scope of the described embodiments.

[0024] Embodiment 1

[0025] As Figure 1-2As shown in the figure, this embodiment provides a tightening device for irregular screws. The tightening device includes: a fixing plate 1, a Y-axis module 2, an X-axis module 3, a Z-axis module 4, and a tightening gun 5; the Y-axis module 2 is vertically installed on the fixing plate 1; the X-axis module 3 is horizontally installed on the Y-axis module 2; the Z-axis module 4 is installed on the X-axis module 3 and is perpendicular to the X-axis module 3; the tightening gun 5 is installed on the Z-axis module 4.

Specifically, the Y-axis module 2 is the basic module of the tightening device in this embodiment and is fixed on the fixing plate 1. Therefore, when selecting the Y-axis module 2, it is necessary to consider that the coverage range of the Y-axis module 2 needs to be greater than the distribution range of the screws. A connecting plate 6 is installed on the Y-axis module 2, and a slide rail 11 is provided on the connecting plate 6. The X-axis module 3 is installed on the slide rail 11, and the slide rail 11 can drive the X-axis module 3 to move up and down on the Y-axis module 2. A connecting bracket 7 is mounted on the X-axis module 3 and can move horizontally on the X-axis module 3; the Z-axis module 4 is fixed on the connecting bracket 7 and can move along with the horizontal movement of the connecting bracket 7. In this embodiment, the tightening work of irregularly distributed screws is realized by the up and down and horizontal position movements of the X-axis module 3 and the Z-axis module 4 respectively.

[0028] As Figure 5 shown, in this embodiment, a sleeve 8 is sleeved on the tightening gun 5, and the sleeve 8 is used to tighten the screw. In addition, a control interface is provided on the tightening gun 5 for connecting to an outgoing line controller. Specifically, the sleeve 8 is installed at the top of the tightening gun 5 for installing a tightening head, and different tightening heads can be matched according to different models and depths of the screws, so as to contact the screw for tightening; a control interface is provided at the rear end position of the tightening gun 5, and this control interface is used to connect to an outgoing line controller. The operator can preset the corresponding tightening torque in the outgoing line controller according to the model and depth of the screw to be tightened. When the screw needs to be tightened, the screw can be automatically tightened without manual operation, improving work efficiency. In addition, when installing the sleeve 8, it should be noted that the tightening gun 5 and the sleeve 8 should be kept on the same straight line to avoid incorrect settings of the outgoing line controller, resulting in the screw being twisted and affecting the use of the workpiece.
