Abstract

The invention discloses a dynamometer and hydraulic mixed loading table for testing the reliability of a power servo knife rest. The table comprises a power servo knife rest supporting part, a cutting force loading part and a power head loading part, wherein a power servo knife rest cushion plate (3) in the power servo knife rest supporting part is fixedly connected with a top plate of a power servo knife rest base (2); the power servo knife rest base (2) is fixed on the lower left part of horizon iron; the cutting force loading part comprises an analog knife rod (5), a cutting force loading supporting device and a cutting force loading device; the cutting force loading supporting device is fixed on the horizon iron on the upper right part of the power servo knife rest base (2); the cutting force loading device is fixed on the cutting force loading supporting device; the analog knife rod (5) is arranged on a knife disc; and the power head loading part arranged on the right side of the power servo knife rest supporting part comprises a bearing loading device (22), a bearing loading device base (23), a No.2 loading rod (21) and a dynamometer (25).

Description

technical field [0001] The invention relates to a test device applied to the reliability field of CNC machine tool power servo tool holders. The reliability test bench of the power servo tool holder is loaded by the dynamometer and hydraulic pressure mixed for the reliability test. Background technique [0002] In recent years, with the rapid development of the equipment manufacturing industry, my country has become a big country in the production and application of CNC machine tools. At present, the domestically developed CNC machine tools have made significant progress in precision, speed, large-scale and multi-axis linkage. However, with the increase of functions, the hidden dangers of failures increase, the advanced functions and performance indicators cannot be maintained, and the reliability problem is serious. It has become the focus of attention of enterprises, users and sales markets and the bottleneck of the development of CNC machine tool industry. One of the mai...
