The invention discloses a motorized spindle three-dimensional force loading device, and relates to the field of motorized spindle testing. The device comprises a bottom plate; a torque loading device which is used for testing the torque performance of the motorized spindle, wherein the torque loading device and the motorized spindle are both arranged on the bottom plate, and the torque loading device is in transmission connection with the motorized spindle; a sleeve shell which is rotatably arranged on the electric spindle in a sleeving mode, wherein the position of the sleeve shell is fixed in the axis direction of the electric spindle; a radial force loading device which is used for testing the radial force performance of the motorized spindle, is arranged on the bottom plate, is used for providing radial loading force perpendicular to the axis direction of the motorized spindle, and is fixedly connected with the sleeve shell; an axial force loading device which is used for testing the axial force performance of the motorized spindle, is arranged on the bottom plate and is used for providing axial loading force along the axis direction of the motorized spindle; and a middle force transmission structure which is connected with the sleeve shell and the axial force loading device. The device can realize related tests of the performances of the motorized spindle in three aspects of torque, radial force and axial force.
Description
technical field [0001] The invention relates to the field of electric spindle testing, in particular to a three-dimensional force loading device for an electric spindle. Background technique [0002] At this stage, the high-precision machining of CNC machine tools has become a core factor that determines the country's comprehensive capabilities. For the electric spindle, the core component of CNC machine tools, its performance directly determines the accuracy, performance and processing quality of the entire system. When the electric spindle is actually working, the spindle drives the tool handle to cut the workpiece. At this time, the force on the electric spindle is the torque force of the tool handle due to the rotating cutting, the radial force brought by the feed of the tool handle and the heating of the spindle. Axial force caused by axial elongation or other factors. However, most of the existing electric spindle test systems, including related test systems for moto...
