The invention relates to a novel loading experiment device for a numerical control turntable, which comprises a workbench and an electric control cabinet. An X-axis box body and an angle rotating and measuring mechanism are arranged on the workbench; an X-axis linear motion pair is installed on the X-axis box body; the X-axis box body is connected with a Y-axis box body through a guide rail; a Y-axis linear motion pair is installed on the Y-axis box body; a Y-axis support plate I is connected with the Y-axis box body through a Y-axis linear motion pair; a hydraulic oil cylinder is installed on the Y-axis support plate, and Z-axis feeding is realized through the hydraulic oil cylinder; the hydraulic oil cylinder is connected with one end of a force sensor; the other end of the force sensor is connected with a loading connection rod; the loading connection rod is in contact with a measured turntable; and the force sensor is connected with the electric control cabinet through a line. The novel loading experiment device is suitable for numerical control turntables with various types and models and can also load at any position of the numerical control turntable to obtain more complete experimental data. The novel loading experiment device has the advantages of simplicity in operation and adjustment, accurate loading experiment results, and flexible and diversified test modes and methods.
