DEVICE AND A METHOD FOR EVALUATING PROPERTIES OF A FRICTIONAL FORCE OF AN LM GUIDE CAPABLE OF STABLY ADDING A LARGE LOAD AS MOVABLE BLOCKS ARE INSTALLED RESPECTIVELY ON THE SURFACES OF A RAIL FACING EACH OTHER

摘要

PURPOSE: A device and a method for evaluating properties of a frictional force of a linear motion (LM) guide are provided to stably and accurately measure the properties of the frictional force of the LM guide that loads the cells for measuring a pressing force and a frictional force installed on a movable block.;CONSTITUTION: A device for evaluating properties of a frictional force of an LM guide includes a measuring unit (100) and a conveying unit (200). The measuring unit measures the properties of the frictional force of the LM guide. The conveying unit transfers the measuring unit. The measuring unit includes a movable block (110), a pressing force measuring load cell (120), a housing unit (130), a pressing force controlling unit (170), and a frictional force measuring load cell (140). The movable block is composed of an upper movable block (111) and a lower movable block (112). The upper and lower movable blocks are installed respectively on the top surface and the bottom surface of a rail (R) of the LM guide. The pressing force measuring load cell, which is installed on the upper movable block, presses the upper movable block and measures the pressing force simultaneously. The housing unit receives the pressing force measuring load cell and the movable block on the upper and lower parts.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Rail longitudinal direction
