Abstract

The invention relates to an electric spindle reliability test bed with a hydraulic-type energy recovery function. The test bed comprises an electric spindle, an electric spindle support portion, a loading bar, a bearing loading unit, a radial force loading portion, an axial force loading portion, an automatic control portion, a torque loading portion and a hydraulic oil way portion. The electric spindle, the loading bar, the bearing loading unit and a shaft axis of a hydraulic pump are coaxial. A loading rod 1 of the radial force loading portion is perpendicular to a shaft axis of the bearing loading unit. The axis of a loading rod 2 of the axial force loading portion is parallel to the shaft axis of the bearing loading unit. The electric spindle is in shaft connection with a hydraulic pump of the torque loading portion through a loading rod 3 and an elastic coupler. According to the arrangement, by subjecting the hydraulic pump and an energy storage to loading, the torque loading is performed on the electric spindle; besides, axial and radial force loading is performed to the electric spindle by the aid of hydraulic oil generated from the hydraulic pump through a hydraulic cylinder, so that the energy is recycled and saved.

Description

technical field [0001] The invention relates to a reliability experiment device applied to high-speed electric spindles of CNC machine tools, in particular to an electric spindle reliability capable of realizing dynamic and static cutting force and cutting torque loading on the electric spindles of CNC machine tools with hydraulic energy recovery Test Bench. Background technique [0002] The electric spindle is one of the key functional components of the CNC machine tool, and its reliability level directly affects the reliability of the CNC machine tool. Therefore, it is of great significance to carry out the reliability test on the electric spindle. Reliability research is generally through the collection, modeling and analysis of fault data. There are two ways to obtain fault data. One is obtained through on-site reliability tests, and the other is obtained through the establishment of an electric spindle reliability test bench in the laboratory. For a long time, most ...
