Abstract

The invention discloses a rolling linear guide friction force dynamic detection device and detection method thereof. The device comprises a bed body, a servo motor, a worktable, a mother lead screw, arolling linear guide, a slide block, an S type tension sensor, a forward limit switch, a reverse limit switch, a motion control card, a control panel and the like; based on the detection method of the device, firstly parameter is set, loading and running-in are carried out on the linear guide to be detected, then dynamic measurement is carried out on friction force and the measured data is analyzed, and finally the test data and result is saved and printed, qualification decision is given and measurement process is finished. The method of the invention can display distribution situation of dynamic measurement data in real time by a computer, and maximum, minimum and mean value thereof are calculated and compared with design standard of corresponding product and then are judged to be qualified or not; compared with the existing static detection method, the method has the advantages of high efficiency, high stability and high reliability.

Description

technical field [0001] The invention belongs to the technical field of dynamic detection of friction force, in particular to a device for dynamic detection of friction force of a rolling linear guide pair and a detection method thereof. Background technique [0002] The rolling linear guide rail pair is generally composed of guide rails, sliders, reversers, rolling elements and cages. It is a new type of rolling support for relative reciprocating linear motion, which can be replaced by steel ball rolling between sliders and guide rails. Direct sliding contact, and the rolling elements can achieve infinite circulation in the raceway and slider with the help of reversers. The rolling linear guide pair has the advantages of small friction coefficient, high running accuracy, no crawling, wear resistance, high rigidity, and small thermal deformation, and is widely used as a guide component for high-precision CNC machine tools and machining centers. And its friction directly refl...
