发明名称 INSPECTION APPARATUS OF HOLE SIZE AND INSPECTION METHOD OF HOLE SIZE
摘要 The present invention relates to a hole size inspection device and a hole size inspection method. The present invention provides the hole size inspection device and the hole size inspection method, capable of classifying a product of good quality and a defective product by easily inspecting the size of a float hole. The hole size inspection device is to inspect the size of a hole of a float capable of rotating around a float arm, which is a center axis, inserted into the hole wherein the hole through which the float arm is inserted is installed in the float; and the float being able to float by buoyancy of a fluid. The hole size inspection device comprises: a supporting unit to support the float arm; a rotation unit rotating the float in one direction by being in contact with the float to rotate the float combined to the float arm supported by the support unit; a rotation number detecting unit to detect a rotation number of the float rotated by the rotation unit; and a control unit determining a defect of the float by comparing N1 to NR if the rotation number of the float detected by the rotation number detecting unit is N1, and a standard range of the rotation number of the predetermined float is NR.
