The present invention relates to an apparatus for inspecting a piston-ring hole in a piston mounting base, and a method for measuring a piston ring hole gap using the same. According to a first aspect of the present invention, there is provided a device for inspecting a piston ring root gap of a piston mounting base, the piston ring root gap inspecting apparatus comprising: a support frame; And a band insertion groove 18 formed in the support frame 16 and into which an steel band 17 of a tensile end 13a is inserted. The piston 2, to which the piston ring 3 to be measured is coupled, A piston insertion port 11 into which the piston is inserted; One side of the steel band 17 is coupled to the support frame 16 so that the steel band 17 applies a tensile force to the outer circumferential surface of the piston ring 3 to be measured and the band insertion groove 18 of the piston insertion port 11 A tension end 13a to which the other side of the steel band 17 passed through the lever portion 13 is engaged; A lever portion (13) rotatably coupled to the support frame (16) and applying a tensile force to the steel band (17) by a rotational force; A dial gauge (12) indicating the degree of change in the claw clearance (s1) of the piston ring (3) to be measured, which is changed by the tensile force of the steel band (17); And the value of the indicating needle of the dial gauge 12 which is changed by the operation of the lever part 13 and the value of the slit clearance s1 of the reference piston ring 1 inputted through the input part 15 And a control unit (14) for calculating and calculating a value of a claw clearance (s1) of the subject piston ring (3). The second aspect of the present invention also includes a first step in which the control unit 14 receives through the input unit 15 a measured value measured by a clearance gauge after insertion into a ring gauge for one reference piston ring 1; As the piston portion 2 to which the reference piston ring 1 is coupled is received by the piston insertion port 11 and the lever portion 13 is pulled by the user, the clearance s1 of the reference piston ring 1 (S1) measurement to the measurement object piston ring 3 by performing zero point correction to set the number indicated by the pointer of the dial gauge 12 at '0' Step 2; The controller 14 controls the piston ring 3 to be measured as the lever portion 13 is pulled by the user after the piston 2 loaded with the piston ring 3 to be measured is received by the piston inserting port 11, A third step of reading the changing position of the indicating needle of the dial gauge 12 by the tensile force of the steel band 17 acting on the outer peripheral surface of the dial gauge 12; And a fourth step of performing an arithmetic operation for calculating a value of the slotting clearance s1 of the measurement object piston ring 3 using the changed position of the indicating needle of the dial gauge 12 read out by the control unit 13 The position of the indicating needle of the dial gauge 12 is changed by disposing the steel band 17 on one side of the steel band 17 while the other side of the steel band 17 is engaged with the supporting frame 16, The band 17 of the tension end 13a to which the other side of the piston ring 3 is coupled to the lever portion 13 is changed by applying a tensile force to the outer circumferential surface of the piston ring 3 to be measured, The value of the clearance s1 is a value of the indication needle of the dial gauge 12 to which the control unit 14 is changed by the operation of the lever unit 13 and a value of the indication needle of the reference piston ring 1 inputted through the input unit 15. [ (S1) value of the piston ring 3 to be measured by using the value of the sprocket clearance s1 Has a piston mounted in the piston ring based hapgu hapgu piston ring gap clearance measuring method using a test apparatus as gong to provide. Thereby, it is possible to save time and manpower in the measurement of the crack clearance for a large number of piston rings. The present invention also provides the effect of automatically measuring the gap clearance in the state where the piston ring is fitted in the piston.
