- Patent Documents 1 and 2 Conventionally, various measuring devices for measuring the inner circumference of an annular bead member have been proposed (for example, see Patent Documents 1 and 2).
- a columnar measuring table composed of two semi-columnar divided bodies is arranged inside a bead member.
- the divided members are moved in the direction of separating each other so that the outer peripheral surfaces of the divided members are in close contact with the inner peripheral surface of the bead member.
- the inner circumferential length of the bead member is measured based on the separation distance between the divided bodies and the circumferential length of the outer circumferential surface of the divided body.
- the bead member is deformed because a force for expanding the diameter is applied. Therefore, it is disadvantageous for improving the measurement accuracy of the inner circumference.
- a roller is pressed directly into contact with the inner peripheral surface of the bead member. And this roller is rolled on the inner peripheral surface of a bead member, and is rotated 1 time in the circumferential direction.
- the inner peripheral length of the bead member is measured based on the number of rotations of the roller at this time. Since the inner peripheral surface of the bead member is directly pressed by the roller, deformation occurs. Therefore, it is disadvantageous for improving the measurement accuracy of the inner circumference.
- An object of the present invention is to provide a circular member inner peripheral length measuring apparatus capable of measuring an inner peripheral length with high accuracy without applying an unnecessary load to the circular member.
- an apparatus for measuring the inner circumference of a circular member includes a table on which the circular member is placed, a two-dimensional sensor that is movably installed on the table, and the two-dimensional sensor.
- a sensor is disposed at a predetermined measurement position, and the two-dimensional sensor is rotated by the rotational drive mechanism around a predetermined position inside the circular member, thereby separating the two-dimensional sensor from the inner peripheral surface.
- the inner circumferential length of a circular member that is placed flat on the pedestal in an unconstrained state is measured, and a two-dimensional sensor that does not contact the circular member is used for the measurement. Therefore, unnecessary load is not applied to the circular member, and forced deformation does not occur. Therefore, it is advantageous to accurately measure the inner peripheral length of the circular member.

- the surface of the mounting table 4 is provided with a plurality of projecting portions 7 that project from the surface at intervals. Each projecting portion 7 is moved by a retracting mechanism 7 a so that it can appear and retract with respect to the surface of the mounting table 4.
- An air cylinder, a hydraulic cylinder, or the like can be used as the retracting mechanism 7a.
- the two protrusions 7 are used as a set, and the interval and position in plan view of the protrusions 7 to be set are set based on the inner diameter of the circular member 12 to be measured.
- the two-dimensional sensor 8 is arranged at the center of the table 4 in plan view, and is arranged inside the circular member 12 that is laid flat on the table 4.
- the two-dimensional sensor 8 is movable in the radial direction of the circular member 12 by the horizontal movement mechanism 10b. Thereby, the two-dimensional sensor 8 arranged facing the inner peripheral surface 12a of the circular member 12 placed flat can move in a direction approaching and separating from the inner peripheral surface 12a.
- the two-dimensional sensor 8 and the horizontal movement mechanism 10b are supported by a rotating shaft 9 that is disposed at a predetermined position (for example, the center of the mounting table 4) of the mounting table 4 and extends vertically in plan view.
- the rotary shaft 9 is driven to rotate about its axis by the rotary drive mechanism 10a.
- the two-dimensional sensor 8 is driven to rotate about the rotation shaft 9.
- a laser sensor can be used as the two-dimensional sensor 8.
- the two-dimensional sensor 8 reflects the irradiated laser light on the inner peripheral surface 12a, and receives the reflected laser light, so that the separation distance d from the two-dimensional sensor 8 to the inner peripheral surface 12a is not contacted with the circular member 12. taking measurement.
- the two-dimensional sensor 8 does not irradiate the laser beam to only one point on the inner peripheral surface 12a, but irradiates a range of a certain length at a time to the two-dimensional sensor 8 and the inner peripheral surface 12a in the irradiated range.
- the separation distance d is measured.
- the separation distance d measured by the two-dimensional sensor 8 is input to the calculation unit 11.
- the distance w between the position of the rotary shaft 9 (axial center) in plan view and the two-dimensional sensor 8 is also input to the calculation unit 11.
- the mounting table 4 In order to place the circular member 12 flat on the mounting table 4, first, as illustrated in FIG. 3, the mounting table 4 is raised at a predetermined angle. Then, the two projecting portions 7 selected based on the inner diameter of the circular member 12 are made to project from the surface of the mounting table 4.
- the inclination angle of the stand 4 in a standing state with respect to the horizontal is, for example, 45 ° to 75 °.
- the circular member 12 is transferred to the mounting table 4 by engaging the inner peripheral surface 12 a of the circular member 12 with the two protruding portions 7 protruding from the surface of the mounting table 4. As a result, the circular member 12 is in a state in which the inner peripheral surface 12 a is supported by the two projecting portions 7 and the lower surface 12 b is supported by the convex support portion 6. In the case of the large circular member 12, it is transferred using a crane or the like.
- the table 4 is lowered by the hoisting mechanism 3 to make it horizontal. Thereafter, the protruding portion 7 is immersed under the surface of the mounting table 4. Thereby, the circular member 12 is placed flat on the mounting table 4 in an unconstrained state.
- the inner diameter of the circular member 12 for measuring the inner peripheral length L is not particularly limited, for example, the present invention can be applied even if the inner diameter is in the range of 500 mm to 2000 mm.
- the circular member 12 can be positioned with respect to the mounting table 4 by engaging the inner peripheral surface of the circular member 12 with the two protruding portions 7 in the mounting table 4 in the standing state.
- the position of the protrusion 7 in the mounting table 4 in plan view is set at a position where the circular member 12 can be positioned at a desired position when placed flat.
- the position of the protrusion 7 in the mounting table 4 in plan view is set so that the position of the circle center of the circular member 12 when placed flat is within a range of 20 mm or less from the position of the rotary shaft 9.
- the standing table 4 is difficult to stably hold the circular member 12. Ensure a reasonable spacing.
- the position of the projecting portion 7 for positioning the circular member 12 at a desired position when flat is different. Therefore, for example, for each size of the inner diameter of the circular member 12, an appropriate plan view position and interval of the two protruding parts 7 to be used may be set, and the protruding part 7 may be installed at the appropriate position.
- the center is set to be approximately the position of the rotation shaft 9. Since various circular members 12 having different inner diameter sizes can be accurately positioned at a desired position with respect to the mounting table 4 and placed flat, it has high versatility.
- the two-dimensional sensor 8 facing the inner peripheral surface 12a of the circular member 12 is moved by the horizontal movement mechanism 10b toward the inner peripheral surface 12a as necessary and stopped at a predetermined measurement position. That is, the two-dimensional sensor 8 is moved so that the inner peripheral surface 12a falls within the measurable range of the two-dimensional sensor 8. Therefore, if the inner peripheral surface 12a of the circular member 12 placed flat on the mounting table 4 in an unconstrained state is within the measurable range of the two-dimensional sensor 8 at the initial position, the two-dimensional sensor 8 is moved horizontally. There is no need to move the mechanism 10b. By adopting the horizontal movement mechanism 10b, the two-dimensional sensor 8 can be easily set in a measurable range with respect to various circular members 12 having different inner diameter sizes.
- the two-dimensional sensor 8 positioned at a predetermined measurement position is rotated about the rotation shaft 9 while the separation distance d from the two-dimensional sensor 8 to the inner peripheral surface 12 a is reached. And the separation distance d is measured over the entire circumference of the circular member 12.
- the measured separation distance d is input to the calculation unit 11. Since the distance w between the rotary shaft 9 in plan view and the two-dimensional sensor 8 at a predetermined measurement position can be grasped, this distance w is also input to the calculation unit 11. Therefore, the distance (w + d) from the axial center of the rotating shaft 9 in plan view to the inner peripheral surface 12a can be grasped in the range of the entire circumference of the circular member 12.
- the angle at which the two-dimensional sensor 8 rotates about the rotation axis 9 from the measurement of the separation distance d at a certain position to the measurement of the separation distance d at the next position is a minute angle A (rad).
- the minute angle A is about 2 ⁇ / 15000 (rad).
- the two-dimensional sensor 8 irradiates a laser beam to a predetermined length range in the vertical direction at a time, and measures the separation distance d between the two-dimensional sensor 8 and the inner peripheral surface 12a of the irradiated range. Therefore, as the separation distance d for calculating the inner circumferential length L, for example, any vertical direction such as a separation distance d at the center position in the vertical direction of the inner peripheral surface 12a or a separation distance d at a predetermined vertical position. A separation distance d at the position can be employed.
- the inner peripheral length L of the circular member 12 placed flat on the pedestal 4 in an unconstrained state is measured using the two-dimensional sensor 8 that is not in contact with the circular member 12. Therefore, an unnecessary load is not applied to the circular member 12, and forced deformation does not occur. Therefore, it is advantageous to accurately measure the inner circumferential length L of the circular member 12.
- the surface of the adjacent portion of the pedestal 4 adjacent to the circular member 12 laid flat on the pedestal 4 in an unconstrained state is a low reflection surface 6a that diffusely reflects the laser light emitted by the two-dimensional sensor 8.
- the upper surface and the inner peripheral side end surface of the convex support portion 6 are low reflection surfaces 6a that have been subjected to blasting or the like that makes the surface minute unevenness.
- the protrusion 7 When the separation distance d is measured by the two-dimensional sensor 8, the protrusion 7 is immersed below the surface of the mounting table 4. For this reason, the projecting portion 7 does not block the laser light emitted by the two-dimensional sensor 8 from getting in the way.
- the circular member 12 is supported by the convex support portion 6 protruding upward, it becomes easy to align the measurement center of the two-dimensional sensor 8 and the vertical center of the inner peripheral surface 12a of the circular member 12. Yes. And in the part which is not supported by the convex support part 6 of the circular member 12, since the internal peripheral surface 12a will be in the state which floated in the air, the adjacent part of the mounting base 4 adjacent to the internal peripheral surface 12a will become the minimum. . Accordingly, it is advantageous to reduce measurement noise when measuring the separation distance d by the two-dimensional sensor 8.
- the gantry 4 can be a horizontal gantry 4 without adopting a undulating configuration.
- the mounting table 4 is installed on the upper surface (framework) fixed to the frame 2 horizontally.
- the circular member 12 in a lying state is placed on the mounting table 4.
- the circular member 12 is hung in a state of being laid down by a crane or the like and transferred to the table 4.
- the vertical movement mechanism 10c moves the two-dimensional sensor 8 in the vertical direction.
- a hydraulic cylinder or the like can be used as the vertical movement mechanism 10c.
- the two-dimensional sensor 8 Before measuring the inner circumferential length L, the two-dimensional sensor 8 is positioned at a position facing the inner circumferential surface 12a of the circular member 12 by the vertical movement mechanism 10c. The two-dimensional sensor 8 positioned in the measurement position in this way measures the separation distance d from the two-dimensional sensor 8 to the inner peripheral surface 12a while rotating around the rotation shaft 9, and the entire circular member 12 is measured. The separation distance d is measured in the circumferential range.
- the method for calculating the inner circumferential length L of the circular member 12 is the same as in the previous embodiment.
- the two-dimensional sensor 8 can be accurately positioned at a desired position according to the vertical position of the inner peripheral surface 12a.
- the two-dimensional sensor 8 is moved to a position below the surface of the mounting table 4 or the surface of the frame 2 to stand by. Thereby, troubles, such as the circular member 12 and other things which are moving colliding with the two-dimensional sensor 8 and being damaged, can be avoided.
