Comprehensive Test System Development Of Roller Linear Guide

Roller linear guides is a key feature of the CNC machine tools, which has been used in precision machinery, machine tools, automation, power transmission, semiconductors, industrial robots, measuring instruments, medical and aerospace, etc.with the continuous development of equipment manufacturing technology,it has higher requiremnt of the performance of the roller linear guide,which is the core components of CNC machine tools. high-speed, overloaded are the directions of roller linear guides’development. It can affect the performance of temperature, noise and vibrationin in this circumstance,which will in turn affect the quality of roller linear guide,nowadays,Foreign countries have mature testing methods and tools, In order to improve the performance of the roller linear guide, the performance testing technology is essential. The foreign Guide manufacturing company,in addition to reform the process, regarding the upgrading of the detection means on the important position. The international community has formed a relatively complete set of linear guide performance testing system, including life testing machine and contact stiffness measurement machine. But it is not open to the public in many advanced technology manufacturing and testing technology, it is difficult to find information on the performance testing of roller linear guides from abroad.however,there is few roller linear guides comprehensive performance test in domestic, which has restricted the development of products, therefore,it is necessary to develop a comprehensive performance testing system.Based on researching analysis on guide performance testing of roller linear in domestic and internationalCombined with relevant national standards and the actual needs,concentrated on roller linear guide testing requirements in high-speed or overload condition, By designing of the mechanical detection platform, Analyzing of the test principles and means of the test parameters, the paper developed a set of roller linear guide comprehensive performance testing system, realized the test and analysis of different sizes of high-speed, overloaded, precision roller linear guide vice performance parameters (noise, vibration, temperature, etc.) Detection platform for the design requirements and testing indicators, combined with roller linear guides of the structural characteristics and working principles of the overall program to determine the comprehensive performance test systems for roller linear guides, and complete mechanical design and hardware selection of the test platformchoice; based on motion control theory to determine the way of motion control, complete motion control system functional modules; after analyzed the characteristics of each test subsystems, completed the performance testing subsystem design; in accordance with the design of motion control and signal acquisition do software programming, realizing the motion control of the roller linear guides the comprehensive performance test system, data acquisition and processing, data storage and removal, and report generation functions. Test system bases on Labview platform,which builds the set of linear motor motion control, data acquisition, display, storage, and generate reports as a whole, it can achieve real-time detection of roller linear guides, vice no-load and load condition, speed, acceleration, temperature, noise, vibration and other performance parameters.Applicate the development software to detect LR55series roller linear guides, and analyze the test results and evaluate the performance of roller linear guides effectively..The successful application of the system has met the test requirements of mechanical field, high-end CNC machine tools key features-roller linear guide pair of high-speed, precision testing for high-speed, it provided a technology guarantee for the performance test of high-speed, overloaded, precision roller linear guid,and Provide the basis for the development of new products and shorten the development cycle, improve product quality.By now,the system has been successfully applied in the enterprise,which has achieved good results,and been recognized by the enterprise.
