Description

Detailed Description of the Invention A. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving mechanism that moves a test machine in, for example, a rotation test device.

B. SUMMARY OF THE INVENTION The moving mechanism of the present invention is provided with a first inclined surface on one side of a slide base and a second inclined surface that is inclined in a direction opposite to the first inclined surface on a base at a portion facing the first inclined surface. Provided,
Move the slide base in the width direction by moving means,
The first inclined surface and the second inclined surface are engaged to position the slide base in the width direction, and the other side of the slide base is fixed by the fixing means, so that one side of the slide base can be accurately adjusted. In addition, it is designed to perform a fixed operation with high fixed rigidity.

C. 2. Description of the Related Art In a rotation tester (transmission tester, clutch tester, torque converter tester), when the EUT is replaced, the EUT is moved. Since the rotation test equipment is a high rotation test equipment, it is necessary to move the EUT accurately and easily.

The conventional moving mechanism of the EUT will be described with reference to FIGS. 4 and 5.

An input side device 3 is provided on one end side of the bed 2 of the rotation test device 1, and a base 4 is provided on the other end side of the bed 2. A slide base 5 is supported on the base 4 so as to be able to move toward and away from the input side device 3, and a test device 6 is mounted on the slide base 5. Reference numeral 7 in the figure is a handle, and the slide base 5 is moved through the handle 7. Guide rails 8 are provided on the bases 4 on both sides of the slide base 5, and the slide base 5 moves while being restricted in the width direction by the guide rails 8. Positioning and fixing of the slide base 5 are performed by bolts 9 provided on both sides of the slide base 5.

When replacing the EUT 6, the bolt 9 is loosened and the slide base 4 is moved to separate the EUT 6 from the rotation test apparatus 1. A new EUT 6 is attached to the slide base 4, the slide base 4 is moved along the guide rail 8 to connect the EUT 6 and the rotation test apparatus 1, and the slide base 4 is fixed by the bolts 9 on both sides. To do.

Since the width direction of the slide base 4 is restricted by the guide rails 8, the rotation centers of the rotation test apparatus 1 and the EUT 6 can be easily matched.

D. Problems to be Solved by the Invention The moving mechanism of the conventional EUT described above is based on the slide base 4.
Since the position fixing bolts 9 are provided on both sides of the slide base 4, the workability of fixing and releasing the slide base 4 is poor. Further, since the accuracy of movement of the slide base 4 in the width direction depends on the accuracy of attachment of the two guide rails 8, it is easy for rattling to occur and it is difficult to secure the centering accuracy of the rotation center with high accuracy. .

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a moving mechanism capable of securely fixing a slide base in a short time and accurately and easily positioning in the width direction.

E. Means for Solving the Problems The constitution of the present invention for achieving the above object maintains a constant position in the width direction orthogonal to the moving direction of the slide base when the slide base is reciprocally moved on the base. Is a moving mechanism in which the slide base is fixed to the base, and a first sloped surface parallel to the moving direction of the slide base is provided on one side of the slide base. A second sloping surface that is slanted in the opposite direction and is slidably in contact with the first sloping surface is provided on the base so as to face the first sloping surface, and a moving unit that moves the slide base in the width direction is provided in the slide base. The other side portion of the slide base is provided with fixing means for fixing the slide base to the base side.

F. The position of the slide base is fixed by moving the slide base in the width direction by the moving means to engage the first inclined surface and the second inclined surface, and fixing the slide base by the fixing means. Due to the engagement between the inclined surfaces, the slide base and the base are always positioned at the same position in the width direction.

G. Embodiment FIG. 1 is a side view of a rotary tester equipped with a moving mechanism according to an embodiment of the present invention, FIG. 2 is an enlarged view of an arrow II in FIG. 1, and FIG. The view in the direction of arrow III is shown.

An input side device (electric dynamometer) 13 is provided on one end side of the bed 12 of the rotation test device 11, and a base 14 is provided on the other end side of the bed 12. A slide base 15 is mounted on the base 14 so as to be able to move toward and away from the electric dynamometer 13.
And a test device (torque converter) 16 is mounted on the slide base 15.

As shown in FIG. 3, a rack 17 is attached to the lower surface of the slide base 15, and the rack 17 meshes with a pinion 18. The pinion 18 is attached to a handle shaft 19, the handle shaft 19 is rotatably supported by the base 14, and a handle 20 is attached to the handle shaft 19. That is, when the handle shaft 19 is rotated by the handle 20, the slide base 15 moves via the pinion 18 and the rack 17.

A first inclined surface 21 is formed on one side surface (right side surface in FIG. 3) of the slide base 15, and the first inclined surface 21 is a parallel surface along the moving direction of the slide base 15.
A guide 22 is fixed to the base 14, and the guide 22 is formed with a second inclined surface 23 that is inclined in the opposite direction to the first inclined surface 21 and is capable of sliding contact with the first inclined surface. The other side surface (the left side surface in FIG. 3) of the slide base 15 is supported by a push guide 24, and the push guide 24 presses the slide base 15 with a push bolt 26 supported by a side plate 25. The push guide 24 and the push bolt 26 constitute a moving means. A pressing plate 27 is provided on the base 14 on the other side surface of the slide base 15, and the pressing plate 27 is locked to the slide base 15 by tightening a fixing bolt 28. That is, the pressing plate 27 and the fixing bolt 28 constitute a fixing means.

As shown in FIG. 2, the push bolt 26 is provided with a pointer 29, and the side plate 25 is provided with an arrow 30. Guideline 2
By matching 9 and the arrow 30, the pressing force of the pressing guide 24 is made constant, and the engagement force between the first inclined surface 21 and the second inclined surface 23 is kept constant.

Next, the operation of the above configuration will be described. By loosening the fixing bolt 28 and the push bolt 26, and rotating the handle 20 to rotate the handle shaft 19, the pinion 18
The slide base 15 moves via the rack 17 and the torque converter 16 moves with respect to the electric dynamometer 13. When the torque converter 16 is moved to a predetermined position, the push bolt 26 is tightened to tighten the push guide 24.
The slide base 15 is moved to the guide 22 side via. When the slide base 15 moves in the width direction, the first inclined surface 21 and the second inclined surface 23 are engaged, and the first inclined surface 21 is pressed in the width direction and at the same time pressed from above. By aligning the pointer 29 of the push bolt 26 with the arrow 30, a prescribed pressing force is generated in the slide base 15, and the slide base 15 is moved in the width direction to the guide 22 via the first inclined surface 21 and the second inclined surface 23. The position is restricted. The slide base 15 is fixed to the base 1 by tightening the fixing bolt 28 and locking the holding plate 27 to the slide base 15.
It is fixed at 4.

According to the moving mechanism described above, one side surface of the slide base 15 is regulated via the first inclined surface 21 and the second inclined surface 23, so that the slide base 15 is fixed by operating the fixing bolt 28 on the other side surface side. The position in the width direction can be maintained at a fixed position by just doing Since the push bolt 26 is provided with the pointer 29 and the side plate 26 is provided with the arrow 30, the pushing force of the slide base 15 can be made constant, and the reproducibility of the regulation in the width direction is excellent. Further, since the structure is simple, the rigidity is high, and the push bolt 26 and the fixing bolt 28 can be operated with a standard tool such as a spanner, and no special maintenance is required.
