A center collar 22 is fitted into the outer hole 17a of the drive plate 17, and a guide bush 19 is slidably fitted into the guide bush 22 and has a thread on the outer side. A drive pin 20 has a notch 19a that contacts the drive boss 1b of the rotary body 1 of the test machine, and a slope 19b on the end face. Similarly to the drive pin 19, the outer pin 20 is slidably fitted inside the guide bush 22. A notch 20a with a slope for sandwiching the drive boss 1b of the rotary body 1 of the test machine with the drive pin 19 without any gap is formed at one end of the drive pin 23, which has a slope 20b formed on the end surface of the guide bush. 22, the rotation prevention groove 17c of the drive plate 17, the rotation prevention groove 19c of the drive pin 19, and the rotation prevention groove 20 of the drive pin 20.
A locking pin 24 is screwed into the outer thread of the guide bush 22 and has a guide shaft inside, and 25 is a locking pin that is inserted into the inner guide hole of the drive pins 19 and 20.

9c, 22 to 25 form a drive pin holding device. 26 is a rotating body of the machine under test, and 27 is a third rotating body of the machine under test.

In the automatic coupling joint device configured as described above, first, before the machine under test is carried into the test equipment, drive pins 19 and 20 are selected at positions that match the drive bosses 1b of the rotating body 1 of the machine under test. Drive pins 19 and 20 are used in which two of these drive pins form a pair and a total of four opposing drive pins form a set. In addition, the center collar 21, which is removably fitted inside the drive plate 17 with one touch, is replaced with one that matches the diameter of one shaft 1a of the rotating body 5 of the machine under test. At this point, the machine under test is carried into the test apparatus, and the automatic coupling joint device of this test apparatus moves forward or backward relative to the machine under test that has been carried in. That is, direct connection is started by the automatic connection joint device of the test equipment moving forward with respect to the machine under test that has been brought in.

At this time, first, one shaft 1a of the rotating body 1 of the machine under test fits into the guide hole 21a of the center collar 21, and the axis of the rotating body 1 of the machine under test is set on the axis of the automatic coupling joint device of the test equipment. . The automatic coupling coupling system of the test device is then advanced to the operating position.
At this time, drive pin 19 and drive pin 20
As shown in Fig. 4, the drive boss 1b of the rotating body 1 of the machine under test
If the position is between 1 and 2, the slope 20b of the drive pin 20 hits the drive boss 1b of the rotating body 1 of the machine under test by rotating the automatic coupling joint device of the test device in a counterclockwise direction. The drive pin 20 slides inside the guide bush 22 and is pushed in, passing through the drive boss 1b, and the notch 19a of the drive pin 19 hits the drive boss 1b, which causes the drive plate 17 to rotate, thereby causing the drive plate 17 to rotate.

Direct connection between the test machine and test equipment is completed.

At this time, if the outer diameter dimension of the drive boss 1b of the rotating body 1 of the tested machine differs due to tolerance, the drive boss 1b is inserted between the drive pin 19 and the drive pin 19 without any gap by the sloped notch 20a of the drive pin 20. . In other words, when the outer diameter of the drive boss 1b is small, the protrusion of the drive pin 20 becomes large as shown in FIG. 6, and when the outer diameter of the drive boss 1b is large, the drive pin 20 protrudes as shown in FIG. The protrusion of 20 becomes small.

Furthermore, when the drive pin 19 is aligned with the drive boss 1b of the rotating body 1 of the machine under test at the start of direct connection, the drive pin 19 is pushed in by the drive boss 1b, as shown in FIG. 8. Also drive pin 20
When the position of the drive pin 20 is aligned with the drive boss 1b of the rotating body 1 of the machine under test, the drive pin 20 is pushed in by the drive boss 1b in the same manner as described above, as shown in FIG. 9.

Next, direct connection between the machine under test and the test device is achieved by rotating the automatic coupling joint device of the test device counterclockwise in the same way as when the drive pin 19 and the drive pin 20 are located between the drive bosses 1b of the test machine rotating body 1. Complete by rotating in the direction.

Next, direct connection tripping after operation is performed by retracting the automatic coupling joint device cover of the test equipment relative to the machine under test. Note that when testing a second or third device under test with different dimensions, the second or third device under test is connected to the test equipment in the same way as when testing the aforementioned device under test. Before the machine is transported, the drive pins 19 and 20 are placed at a position with a diameter that matches the drive boss 26b of the second machine under test rotating body 26 or the drive boss 27b of the third machine under test rotating body 27.
