  • Publication number: 20210197329
    Abstract: A Parts fixture for robot machining and a robot machining system, includes a base plate for connecting with a robot machining platform, and a profiling surface disposed at the base plate for placing parts to be machined. The profiling surface has the same shape as the parts to be machined, and an edge of the base plate is provided with a pressing block for pressing the parts to be machined. The profiling surface can be completely matched with the parts to be machined, it ensures that the bottom of the parts to be machined is supported during the machining, so that the parts to be machined does not vibrate during the machining Therefore the machining accuracy of the parts to be machined can meet the machining requirements.
