However, after long-term use, the card plate or card ball will be worn due to the friction of being pressed down for a long time and the friction in the fixed gun disc, which will affect the tightness of the connection between the gun disc and the robot, thereby affecting the robot's operating accuracy. Summary of the invention

[0007] Preferably, the connecting plate is plate-shaped, the lower end of the pressing ball is spherical, and the pressing ball is slidably connected to the inner side of the connecting cone. Its function is to move downward on the inner side of the rotating gun disc through the connecting plate and the pressing ball, so that the lower end of the pressing ball squeezes the card column, thereby squeezing the card column into the card groove opened on the inner side of the fixed gun disc.

[0008] Preferably, the connecting cone is in a conical shape, the inner side of the connecting cone is hollow, and the outer surface of the connecting cone is provided with a plurality of groups of cylindrical grooves, the function of which is to enable the clamping column to be movably connected to the inner side of the grooves provided on the outer surface of the connecting cone, and the clamping column does not contact the connecting cone, thereby reducing the friction between the clamping column and the connecting cone, thereby preventing the clamping column from being damaged due to long-term sliding friction.

[0009] Preferably, the spring is in a spiral shape, one end of the spring is fixedly connected to a groove provided on the outer surface of the connecting cone, the other end of the spring is fixedly connected to the connecting ring, and the spring is obliquely connected to the groove provided on the outer surface of the connecting cone. Its function is to drive the connecting shaft through the driving mechanism when the gun disc is replaced, so that the connecting shaft is reset, thereby making the connecting plate and the pressing ball also reset, so that under the elastic action of the spring, the clamping column will quickly slide from the inner side of the clamping groove into the groove provided on the outer surface of the connecting cone, thereby completing the separation of the rotating gun disc and the fixed gun disc.

Since the lower end of the connecting plate is spherical, the end of the clamping column close to the pressing ball is squeezed, so that the clamping column moves into the clamping groove opened on the inner side of the fixed gun disc, so that the clamping column is clamped into the inner side of the clamping groove. At the same time, the locating pin fixedly connected on the lower surface of the rotating gun disc is correspondingly inserted into the inner side of the locating hole opened on the upper surface of the fixed gun disc, so that the rotating gun disc is fixedly connected to the fixed gun disc, thereby completing the switching. When the gun disc needs to be replaced again, the connecting shaft is driven by the driving mechanism to reset the connecting shaft, thereby resetting the connecting plate and the pressing ball. Under the elastic action of the spring, the clamping column will quickly slide from the inner side of the clamping slot into the groove provided on the outer surface of the connecting cone, thereby completing the separation of the rotating gun disc and the fixed gun disc. The rotating gun disc is then connected to another set of fixed gun discs through the same operation to complete the switching. Since the diameter of the groove provided on the outer side of the connecting cone is slightly larger than the diameter of the clamping column, the friction between the clamping column and the pressing ball is reduced, thereby avoiding excessive wear of the clamping column, thereby extending the service life of the gun disc.

The pressing ball 4 is slidably connected to the inner side of the connecting cone 5. Its function is to move downward on the inner side of the rotating gun disc 1 through the connecting plate 3 and the pressing ball 4, so that the lower end of the pressing ball 4 squeezes the clamping column 8, thereby squeezing the clamping column 8 into the clamping groove 12 opened on the inner side of the fixed gun disc 10.

[0026] Furthermore, the connecting cone 5 is in a conical shape, the inner side of the connecting cone 5 is hollow, and the outer surface of the connecting cone 5 is provided with a plurality of groups of cylindrical grooves, the function of which is to enable the clamping column 8 to be movably connected to the inner side of the grooves provided on the outer surface of the connecting cone 5, and the clamping column 8 does not contact the connecting cone 5, thereby reducing the friction between the clamping column 8 and the connecting cone 5, thereby preventing the clamping column 8 from being damaged due to long-term sliding friction.

[0027] Furthermore, the spring 6 is in a spiral shape, one end of the spring 6 is fixedly connected to the groove opened on the outer surface of the connecting cone 5, and the other end of the spring 6 is fixedly connected to the connecting ring 7. The spring 6 is obliquely connected to the groove opened on the outer surface of the connecting cone 5. Its function is to drive the connecting shaft 2 through the driving mechanism when replacing the gun disc, so that the connecting shaft 2 is reset, so that the connecting plate 3 and the pressing ball 4 are also reset, so that under the elastic action of the spring 6, the clamping column 8 will quickly slide from the inner side of the clamping groove 12 into the groove opened on the outer surface of the connecting cone 5, thereby completing the separation of the rotating gun disc 1 and the fixed gun disc 10.

[0028] Furthermore, the connecting ring 7 is in the shape of a circular ring, the clamping column 8 is in the shape of a rod, both ends of the clamping column 8 are in the shape of a hemisphere, and the clamping column 8 is in the form of multiple groups of movably connected in the grooves opened on the outer surface of the connecting cone 5.

[0029] Furthermore, the positioning pin 9 is matched with the positioning hole 11, and the card slot 12 is a circular groove. The card slot 12 is matched with the card column 8. Its function is to make the positioning pin 9 fixedly connected to the lower surface of the rotating gun disc 1 correspondingly inserted into the inner side of the positioning hole 11 opened on the upper surface of the fixed gun disc 10. At the same time, the card column 8 slides into the inner side of the card slot 12, so that the rotating gun disc 1 and the fixed gun disc 10 can be quickly connected.

When the gun disc is switched, the connecting shaft 2 is driven by an external driving mechanism, so that the connecting shaft 2 moves downward on the inner side of the rotating gun disc 1, thereby driving the connecting plate 3 to move downward, and then the downward pressure ball 4 moves downward on the inner side of the connecting cone 5. Since the lower end of the connecting plate 3 is spherical, the end of the clamping column 8 close to the downward pressure ball 4 is squeezed, so that the clamping column 8 moves into the card slot 12 opened on the inner side of the fixed gun disc 10, so that the card column 8 is stuck in the inner side of the card slot 12. At the same time, the positioning pin 9 fixedly connected to the lower surface of the rotating gun disc 1 is correspondingly inserted into the inner side of the positioning hole 11 opened on the upper surface of the fixed gun disc 10, so that the rotating gun disc 1 is fixedly connected to the fixed gun disc 10, thereby completing the switching. When it is necessary to replace the gun disc again, the connecting shaft 2 is driven by the driving mechanism to reset the connecting shaft 2, so that the connecting plate 3 and the pressing ball 4 are also reset, so that under the elastic action of the spring 6, the card column 8 will quickly slide from the inner side of the card slot 12 into the groove opened on the outer surface of the connecting cone 5, thereby completing the separation of the rotating gun disc 1 and the fixed gun disc 10. Since the diameter of the groove opened on the outer side of the connecting cone 5 is slightly larger than the diameter of the card column 8, the friction between the card column 8 and the pressing ball 4 is reduced, thereby avoiding excessive wear of the card column 8, thereby extending the service life of the gun disc.
