Abstract

The invention belongs to the technical field of testing of mechanical equipment reliability, and particularly relates to a loading device and a loading method for testing reliability of an electric spindle. The loading device provided by the invention comprises a push rod bracket capable of being fixedly mounted on a work table of a machine tool, a fastening slide block capable of being fixedly arranged on a surface of the push rod bracket through a locking member, a push rod used for applying load to a loading rod on an electric spindle, a loader capable of sleeving an outer surface of the push rod, and a bearing seat used for sleeving one end of the loading rod, wherein one end of the push rod is pivotably connected to the outer surface of the bearing seat; the other end of the push rod can be connected with the locking member. The loading device and the method provided by the invention can be used to effectively simulate influence of radial force and axial force on the electric spindle; the loading device integrally adopts a mechanical structure, is convenient to use, and is beneficial for improving reliability of research on reliability of the electric spindle.

Description

technical field [0001] The invention belongs to the technical field of reliability testing of mechanical equipment, and in particular relates to a loading device and a loading method for reliability testing of an electric spindle. Background technique [0002] The electric spindle is one of the core functional components of the CNC machine tool using high-speed cutting technology, and its main function is to realize the cutting motion of the machine tool. It combines the machine tool spindle and the motor shaft into one, realizing the "zero transmission" of the main motion system. This "zero transmission" not only makes the electric spindle have the advantages of compact structure, high speed, easy balance, high transmission efficiency and accurate positioning, but also simplifies the transmission and structure of the machine tool, and improves the dynamic sensitivity, machining accuracy and Work reliability meets the requirements of "high speed, high precision, high reliab...
