Dynamic performance integrated test experimental device for high speed principal axis

Abstract

The invention discloses an test device of a high-speed main axle dynamic performance integrative test. The device comprises a main axle which is arranged on a main axle positioning pedestal; the main axle positioning pedestal is fixedly connected with a main axle mounting plate; the main axle mounting plate is fixed and limited by limiting and fixing components at the two side edges that is in parallel with the axial direction of the main axle; the main axle mounting plate is connected with a casting base table by a dense ball supporting structure, so that the main axle mounting plate is free in the horizontal plane; the main axle mounting plate is provided with a vibration test part; the casting base table is provided with a vibration frame; the front end of the main axle is connected with an HSK test head; the main axle mounting plate that is opposite to the HSK test head is provided with a sensor support saddle which is provided with a sensor end cover; the sensor support saddle can be connected with three displacement sensors by an index plate arranged on the sensor support saddle; the sensor end cover that is perpendicular to the end surface of the HSK test head can be connected with one displacement sensor. By using the test table, a plurality of test programs can be finished simultaneously, thus greatly improving the integration degree and utilization flexibility of the high-speed main axle performance test.

Description

technical field [0001] The invention relates to an experimental device for comprehensive testing of the dynamic performance of a high-speed spindle. Background technique [0002] At present, the test device for the dynamic performance test of the high-speed (speed exceeding 10000r / min) spindle has the following shortcomings: [0003] 1. The existing high-speed spindle dynamic performance test platform can only test a certain performance of the high-speed spindle, the function is too single, and its integration needs to be improved; [0004] 2. The data acquisition process is complicated, the data processing is too rough, and cannot be processed and displayed online. It is urgent to improve the automation of the spindle dynamic performance test system; [0005] 3. The structural design of the spindle dynamic performance test platform is not perfect, it is impossible to realize the multi-directional installation of the spindle, and to test the dynamic performance of the spind...
