Abstract

Disclosed is a numerical control rotary table reliability testbed with actual working condition simulating loading. The device for a reliability test includes a numerical control turntable part including a numerical control turntable, a simulated load bearing part configured to transmit force to the numerical control turntable, cutting force loading part configured to apply force to the simulatedload bearing part, and a control part configured to adjust the force applied by the cutting force loading part. The numerical control rotary table reliability testbed of the invention can carry out reliability loading tests on numerical control rotary tables of different types and different models, has certain flexibility and versatility, uses electro-hydraulic servo to simulate loading of dynamicand static cutting force on the numerical control rotary tables, and can adjust the magnitude, frequency, angle and time of the cutting force according to working conditions.

Description

technical field [0001] The present invention relates to a comprehensive test device applied to the field of reliability of numerically controlled rotary workbenches of numerically controlled machine tools. Reliability test bench for dynamic and static cutting force loading over time. Background technique [0002] With the vigorous development of the equipment manufacturing industry, CNC machine tools are widely used as high-tech working machines. As the key functional component of CNC machine tool, the reliability level of CNC rotary table directly affects the reliability level of the CNC machine tool. At the same time, the performance index of CNC rotary table will also directly affect the precision index of its processed parts. The reliability test of key functional components of CNC machine tools is the main technical means to obtain product failure data, conduct failure analysis and establish reliability models. Therefore, it is of great practical significance to resea...
