Movement;The work is set in the work holder in the carry-in/out position of the index table.When the index table rotates 90° clockwise to the inspection position, the workholder rotates 90° counterclockwise in synchronization with the rotation.Design point;Calculation process of major partsVerification of thrust load and moment of inertia in index table from load weight and moment of inertiaThrust load and moment of inertia in index tableCondition values: mass of moving object W = 8.7 [kg], acceleration due to gravity g = 9.8 [m/s²], safety factor S = 3, allowable moment of inertia in the index table 0.17 [kg・m²]Thrust load considering safety factor at 8.7 kg of rotating body F=3×8.7×9.8=226[N]　It is safe because it is smaller than the allowable thrust load of 800[N] of the selected index tableMoment of inertia of rotating body: M=0.050 [kg·m²], Moment of inertia considering safety factor (S=3): M1=3×0.05=0.15 [kg·m²]　 Allowable moment of inertia of the selected index table: (0.17 [kg)・m²]), so it is safeEssentials of Structural Fabrication and DesignTo fix the fixed gear, the index table uses a hollow typeThe rotation of the work holder does not need to be controlled and maintenance is easy.The shaft fixing the fixed table is not flanged, but a set collar is used to reduce costs.
