Motorized spindle simulation working condition loading test device

Abstract

The invention discloses a motorized spindle simulation working condition loading test device. The motorized spindle simulation working condition loading test device includes an industrial personal computer (PC), a driving device connected with the industrial PC, a motorized spindle connected with the driving device, and a loading driving mechanism; a test bar is arranged at the motorized spindle; the loading driving mechanism is installed below the motorized spindle; the loading driving mechanism is installed on a test bench base; and a cooling water circulation device and an oil-gas lubrication device are both connected with the motorized spindle. According to the motorized spindle simulation working condition loading test device of the invention, loading of a radial force, an axial force, a torque, vibration and heat cutting can be completed by means of simulation loading gears installed at an end portion of the test bar; the loading can be changed through replacing different types of gears and adjusting the modification coefficients of the meshing gears; and the loading driving mechanism is driven through a preset loading program to continuously move along the axial direction and the radial direction of the motorized spindle, so that the meshing condition of the loading gears can be automatically changed, and therefore, the simulation of automatic and continuous loading of an actual working condition can be completed, and thus, automation degree is high, a simulation condition is closer to an actual cutting working condition, and test data are more authentic.

Description

technical field [0001] The invention relates to a loading test device for simulating working conditions of an electric spindle, in particular to a device for carrying out a loading test of simulating working conditions for a high-speed electric spindle used in a numerically controlled machine tool before leaving the factory and after maintenance. Background technique [0002] Electric spindle is one of the core components of high-speed machining machine tools. It is also a high-performance spindle that integrates motors and rotating spindles in the field of CNC machine tools in recent years. It has compact structure, light weight, small inertia, small vibration, and low noise. Fast response and other advantages, with the development of CNC machining technology from traditional low-speed, low-feed, high-torque cutting to high-speed, high-feed cutting, electric spindles are widely used as high-speed spindle units for CNC machine tools. However, the electric spindle is a comple...

Problems solved by technology

[0003] At present, there is still a big gap between my country's electric spindle research, application and maintenance level and foreign countries. High-speed, high-precision electric spindles mainly rely on imports from Germany, Switzerland and other countries. The electric spindle lacks core technical information, as well as the lack of use and maintenance, resulting in the maintenance and testing of the electric spindle all relying on the electric spindle manufacturer. The maintenance and testing cycle of the electric spindle is long and the cost is high.
