Abstract

PURPOSE:To facilitate measuring operations and to accurately measure the true change by providing one or more electric micrometers, an arithmetic processing unit and an output unit. CONSTITUTION:An object 3 to be measured is positioned by means of stopper pins 4, and cylinders 1, 2 are measured at three points in their circumferences using electric micrometers 11, 12. The measured values are fed to an arithmetic processing unit 15 which makes arithmetic operation based on the measured values at those three points from the electric micrometers 11 to determine the position of center and diameter of the cylinder 1. The position of center and diameter of the cylinder 2 are similarly determined based on the measured values relating to the cylinder 2 from the electric micrometers 12. The unit 15 then compares the computed results for both cylinders 1 and 2 to determine error in diameter and offset of the center position. These computed results are indicated using a cathode ray tube display 16 in the form of numbers and figures, so the observer can confirm easily the result at a glance.

When assembling parts of precision machinery and the like on the same axis, it is important that the axes of each part coincide. For example, when two cylindrical parts with the same diameter are assembled on the same axis and rotated around this axis by υ, if the axes do not match, rotational unevenness or wobbling will occur, making it impossible to obtain the desired rotation. For this reason, after these parts are assembled, the situation is evaluated using a displacement measuring device in order to check whether the axes are aligned with a predetermined position or the state of misalignment.

[Problems of Background Art] However, the above-mentioned devices have various problems in accurately measuring displacement. The first point is to move the dial gauges (5A) and (5B) in the axial direction on the sides of the cylinders (1) and (2+) of the object to be measured (3). ), (5B) must be moved parallel to the axis. If this is moved diagonally, the positions of the points to be measured on cylinder (1) and cylinder (2) will be different, making it difficult to obtain accurate values. The second and more fatal problem is that the diameters of cylinder (1) and cylinder (2) are not completely the same, and the design tolerance range This means that there is some error in the measurement.For this reason, the dial gauge (5A
) and (5B) are values that include the error in the diameters of the cylinders (1) and (2) mentioned above, and the values measured by the centers (1) and (2) of the cylinders (1) and (2) are This will no longer be the true value of the deviation.

The operation of this embodiment achieved by the above-described configuration will be described below. Position the object to be measured (3) with the stopper bottle (4), and place the cylinder (1) with the micrometer [1] and H.
, (2) Measure the positions of three points around each of them. The arithmetic processing unit receives the measured values obtained by the electric micrometers αυ and α. Here, the arithmetic processing unit (15) performs arithmetic processing based on the measurement values at three points of the electric micrometer (1υ) installed in the cylinder (1).
Find the center position and diameter of (1). Also, from the measurement values of the cylinder (2) obtained by the electric micrometer (121), the center position and diameter are determined in the same way as in the book.By this, the arithmetic processing unit calculates the distance between the circle # (1) and the cylinder (2). The calculation results are compared and the diameter error, displacement of the center position, i.e. the amount and direction of axis deviation are determined.These calculation results are displayed numerically and graphically on a cathode ray tube display (I61). Therefore, the measurer can check the measurement results displayed on the cathode ray tube display (1ω) and easily and accurately judge whether the object to be measured (3) is suitable or not.

2) The diameter of each center can be determined by 1 g. For this reason, the amount of axis deviation displayed does not include errors in the design tolerance range of the diameter, and shows the true value. Furthermore, since the measurement values are set at 3 points, if the axes of the cylinders (1,) and (2) are not parallel to each other but tilted, the amount of mutual inclination can also be determined.
