ングの通り芯である。Here, the y-axis and the Y-axis are dial gauges 58a and 58b.
Read with the y-axis, and the y-axis is the dial gauge 59a.
, 59b is used to read the amount of misalignment. That is, by arranging and rotating the dial gauges in this manner, it is possible to judge not only the y-axis and the center of the Y-axis, but also the axis difference between Y and y and the axis difference between X and X from the readings of dial gauges 58a and 59a. Possible, this is the core of the turning spindle and drive coupling.
y軸の差を同時に測定かでき極めて有利なものである。This is extremely advantageous because it allows the difference in the y-axis to be measured at the same time.

を無くしていく。Next, a method for centering each of these x, y, and z axes will be explained. Fig. 10 (- As shown, the centering of the y-axis and the two axes is done by setting the tension poles on the drive frame 19 while checking the dial gauges 58b and 59b) 61a, 61b...
・・・・・・・・・ Alternately adjust the 8 wires up to 61h to eliminate misalignment. In addition, while checking the dial gauges 58a and 59a for centering the Y-axis and the y-axis, leveling rings 46a, 46b, 46c, which constitute spherical seats, are used.
46d (see Figures 3 and 4) alternately to eliminate misalignment.
以上のようにX、Y方向の芯出し操作を繰返して各ダイ
ヤルゲージの読みが零あるいは必要な最小値となったこ
とを確認して芯出しは完了する。Centering is completed by repeating the centering operations in the X and Y directions as described above and confirming that the readings on each dial gauge have become zero or the required minimum value.
即ち、各ダイヤルゲージ58a 、 58b 、 59
a 、 59b。That is, each dial gauge 58a, 58b, 59

完了し順次切削加工を行う。On the other hand, the center of the driving force coupling 55 is determined at the machine factory based on the drive coupling 54 and the axis distance e between the x, y, and z axes.
By performing centering in advance, on-site centering can be saved. Alternatively, centering may be performed on-site using the drive coupling 55 and the turning spindle 5. A presser metal fitting 48 that tightens the drive frame 19 once the core is determined
After final tightening is performed, the drive couplings 54 and 55 are connected to the turning spindles 4 and 5, and the work of centering and fixing the device is completed, and cutting operations are performed one after another.

を特徴とする可搬式内径切削装置。A portable cutting device that performs cutting at the installation position of a workpiece, in which a turning spindle inserted into the inner diameter part to be cut is connected to a one-rotation drive mechanism at one end, and the outer circumference of the turning spindle is connected to a one-rotation drive mechanism. A cutter is held at the end of a cutter holder provided at the end of the cutter so as to be able to move forward and backward, and a telescoping mechanism is attached to the outer periphery of the spindle for adjusting the centering of the turning spindle in the radial direction and fixing it to the inner diameter part. A portable inner diameter cutting device, characterized in that a saddle equipped with a rotational drive mechanism for the turning spindle is movable on a base (in the spindle axis direction and in a direction perpendicular to the spindle axis direction).
