Pressure foot system for multifunctional automatic drilling and riveting end effector and working method

The invention relates to a pressure foot system for a multifunctional automatic drilling and riveting end effector. The pressure foot system is connected with the end effector and comprises a base body, a pressure foot and a driving module, wherein the pressure foot is installed on the base body, and the driving module drives the pressure foot to work. The pressure foot system is characterized in that the pressure foot system is connected with a vacuum chipping sucking device through a pipeline, and a plurality of air blowing channels are formed in a base body pipeline and matched with the vacuum chipping sucking device to form a chipping removal flow field. After an upper computer of the end effector gives a machining object attribute, an electromagnetic proportional valve provides pressing force numerical values for a pressing air cylinder, after the pressing air cylinder drives the pressure foot to press a workpiece, the vacuum chipping sucking device is started, a high-pressure environment is formed on an air blowing opening, a low-pressure environment is formed on an air outlet, a cyclone is formed in the three air blowing channels in a spiral state to form the chipping removal flow field, while starting the drilling work, the end effector does the chipping sucking task, and chippings on a machining site are discharged.
