1 may come into contact with the object to be measured, but since the frame 121 on which the fixed contact 141 is attached is supported by the frame base 123 by the parallel springs 122, the fixed contact 141 may be in contact with the object to be measured. It is easily moved to the left side in FIG. 9 together with the frame 121, and there is no problem in holding the object to be measured on the holding table 71. Furthermore, as the frame 121 moves in the direction of the lateral force, the frame 121 moves up and down with respect to the object holding table 71, but this movement on the plate is within a range that can be ignored in terms of measurement accuracy. It is. In addition, the measurement results may be displayed by displaying only the deviation from the reference body, or by displaying the absolute dimensions based on the dimensions of the reference body. This embodiment has the following effects. The fixed contact 141 and the movable contact 142, which constitute a pair of contacts, are not guided so as to be axially displaceable by a rail heating material or the like and moved forward and backward by a piston or the like.・Parallel barb 12 to stand 123
The movable contact 142 is fixedly held on the frame 121 placed via the frame 121 via the movable contact 142, and is movably supported on the frame 121, and is moved by the rotation of the rotary body 183. Since the structure is configured to move, the number of parts as a whole is small and miniaturization is easy, and in particular, it can be configured to be extremely thin. Therefore, even when measuring a stepped round shaft with a large number of stages, it is possible to arrange a large number of outer diameter measuring heads 50 for each stage, and the range of objects that can be measured is widened. There is an effect. Furthermore, a large number of outer diameter sides 51!
When the heads 50 are arranged and used, the contacts 141 and 142 of all the outer diameter measuring heads 50 can be simultaneously operated by one driving source through the common rotating flit 40. Because it is possible to measure a large number of solar rays, even if a RAD 50 is installed and the temperature is used, the drawings can be seen! It has the effect of "+" (no rl conversion, easy to handle IiV, and quick measurement Z). Still -11)!'r The contacts that make up the contact 141° 147, jilt fC?! This is for inserting the tll constant, and the fixed shim contact 141 is pre-fixed at +21 at a position of 11'' corresponding to the outer diameter of the 1llll constant, and -force is applied. 1, +: It is easy to incorporate the feeding and ejection of the measuring object due to the rotation of the rotating body 183 due to the rotation of the rotating body 183. There is no risk of breakage 414 of the tip of the contact during the process.Furthermore, the fixed contact 141 is not only moved a predetermined distance to the left in FIG. 12] is attached to the frame stand 123 by parallel springs 122, so even if a large-diameter object with the planned dimensions is placed between the solid contacts 141 and 142, it is easy to The fixed contact 141 is moved to the center left side, and the collision between the fixed contact 141 and the object to be measured is immovably avoided, resulting in the effect of a stone. Since the positions of the two workpiece holding stands 71 can be adjusted independently from each other, the center axis of the workpiece can be rotated even if the workpiece has different outer diameters on both ends. 111
1+ A shape that is exactly parallel to the central axis of 40 //
The object to be measured can be easily held. Furthermore, the 1ltll constant object held by the measuring object holding table 71 is driven by the cylinder device d84. Since the pi + pressure rod 1 ( ) 1 holds the object to be measured with a predetermined pressing force on the side of the object holding table 71, the object to be measured will not shift during measurement, and from this point of view, it is possible to maintain highly accurate outer diameter dimensions. There must be an effect that a measurement is taken. Still, since the rotating means 60θ for driving the rotating shaft 40 in forward and reverse directions includes the cylinder device 36, there is no influence of inertial force at the time of one reversal, unlike in a case using a motor or the like, for example. , the reversal can be done quickly and smoothly, and therefore the contacts 141 and 142 can be moved apart and close together very quickly and properly. In addition, in carrying out, 1IllI constant holding compound holding, 1:
They are arranged at both ends of the rotating shaft 40, and can be adjusted independently from each other at -1-'T position R, and are assumed to be λ・].

There is an effect that arranging it is 4 seeds. The object to be measured was held on the holding table 71.
Although the measuring object fixing means is assumed to be held by the pressing rod 101, the measuring object fixing means may be a device such as a rod having a gripping part. one! Although the second bearing at one end of the rotating shaft 40 is removable from the base 30, it may be supported in a non-removable manner. However, the second bearing of the rotation shaft 40 is
If the measurement heads 50 can be attached and detached from 0, the required number of measuring heads 50 can be placed on the base 10 by inserting them through the - end side of the rotating shaft 40, and the shape of the object to be measured can be adjusted. It is easy to make it compatible. In addition, the second block stand 62
is capable of sliding on the base 10, that is, the distance between the workpiece holding stands 71 can be adjusted to FiLJ, and the distance between the workpiece holding stands 71 of each outer diameter measuring head 50 is approximately

It has the advantage of being able to easily automatically measure the outer diameter of stepped round scrolls of any shape. The rotary body 183 of the drive mechanism 210 is assumed to have a handle, 184, and a take-up reel 185, but the invention is not limited to this. It may also consist only of the take-up reel, which is 1 liter per turn.
It is sufficient if the rotation 12j of the body is converted into a linear motion in the axial direction of the contactor 141.'142. ゛ Still rotating body] Reaction H1 force in Fig. 9 of L33 With the rotation in the direction, it is assumed that Frey, ', 121 r is pushed by J・184 and moved slightly to the left side in the figure7, but Freno, 121 is not necessarily moved to the left side.

The L/A l 2.1 may be slidably mounted on the frame stand 123. However, parallel &, ]'
By using the screws 1-22, the overall structure can be made extremely simple, and there is an effect that it can be made as thin as /i. 'Furthermore, the fixed contact 141 may be held by the frame 121 in a manner that the holding position cannot be adjusted. However, if the holding position can be adjusted, each fixed contact 141 of each outer diameter measuring head 50 can be fixed at a position corresponding to each step of the object to be measured, which is convenient because the measurement range is wide. As described above, according to the present invention, it is possible to quickly, reliably, and highly accurately measure the outer diameter of each step of a stepped nine-shaft slider, etc., and it also incorporates a device for supplying and discharging objects to be measured. It is possible to provide an automatic outer diameter measuring machine that can be easily modified.
