寸法どおりか否かを定期的に計測する必要があ
る。Conventional technology The workpiece may not be machined accurately to the desired dimensions due to damage or wear on the cutting edge of the tool, or incorrect programming settings such as the amount of turret movement, and if machining continues as is, the workpiece will be defective. This results in the production of a large amount of workpieces. Therefore, it is necessary to periodically measure whether the processed workpiece has the desired dimensions.

レツト２の一面上に設置されている。 FIG. 3 shows a turret lathe equipped with a conventional automatic measuring device p. The workpiece W being sent through the lathe is held and rotated by the spindle chuck 1.
It is machined into a predetermined shape using various tools on the turret 2. 3 indicates a turret axis, and the turret 2 is movable back and forth in a direction along the turret axis 3, that is, in the Z-axis direction, and is also movable in a direction perpendicular to the turret axis 3, that is, in the X-axis direction. It is. Further, the turret 2 is rotatable around a turret shaft 3. The automatic measuring device p is installed on one side of the turret 2.

クＷの形状を計測する。 When measuring the workpiece W, the turret 2 is rotated so that the automatic measuring device p is at the position of the workpiece W, and then the device p is moved along with the turret 2 in a direction approaching the workpiece W in the Z-axis direction. . next,
The device p is moved together with the turret 2 in the X-axis direction, and the measurement finger 4 is brought into contact with the workpiece W. The shape of the workpiece W is measured based on the amount of movement of the turret 2 at the time of contact.

の測定可能範囲を示している。Problems to be solved by the invention In the conventional example described above, since the automatic measuring device p moves together with the turret 2, the X of the measuring finger 4
The amount of movement l in the axial direction matches the amount of movement of the turret 2 in the X-axis direction. Since the amount of movement of the turret 2 in the X-axis direction is limited, the amount of movement l of the finger is also necessarily limited. This limits the measurable range. m indicates a measurable range when measuring the outer diameter value of the workpiece W, and n indicates a measurable range for the same inner diameter value.

It is rotatable within the cylindrical guide member 26. A stop piece 27 is provided at the end of the shaft 22.
are fixed, and the stop piece 27 can come into contact with the bottom surfaces of stop screws 28 and 29 fixed to the guide member 26. The stop screw 2
8 and 29, the stop piece 27 contacts one screw 28 and rotates 180 degrees from the stopped position, and then the other screw 29
It's starting to come into contact with. The rotary actuator 20 and the guide member 26 are supported by the support member 15.

つた。 With the above configuration, the shaft 22, the measurement detection section 12, and the measurement finger 11 are rotated by operating the rotary actuator 20. This rotation is caused by the stop piece 27 being rotated by the stop screw 29.
It will stop when it comes into contact with. The position of the measurement finger 11 at that time is shown by a two-dot chain line. The measurable range when measuring the outer diameter value of the workpiece W increases from the conventional m to m1, and similarly the measurable range for the inner diameter value increases from n to n1. Therefore, it has become possible to measure the outer diameter of the workpiece W1, which was previously impossible to measure.

響を与えることがない。 Moreover, the error in reversal due to the reversing part can be completely eliminated by adjusting the stop screws 28 and 29, but even if the stopping angle of the measuring finger 11 is
Even if the error Q1 shown in the figure occurs, the error Q1
The error d1 in the diametrical component of the workpiece caused by this is very small and hardly affects the measuring device.
