[Problems to be Solved by the Invention] However, in the above-mentioned prior art, when the index table 3 is raised in the direction of arrow A,
The plurality of workpieces 6 fixed on the top surface of the index table 3 must also be lifted, and the power required to raise the index table 3 becomes large, and a temporary large output is always available. The running costs were also high because of the need to maintain the equipment. In addition, since the index table 3 moves up as shown by arrow A, rotates as shown by arrow B, and then descends as shown by arrow C, the operation time for positioning the workpiece 6 becomes longer. It was hot. For this reason, the total time required for machining using a machine tool was long. Furthermore, when the index table 3 is raised as indicated by arrow A, the processing tool 7 must be fully retreated in the direction of arrow D to avoid colliding with the index table 3. As a result, the space occupied by the entire machine tool increases.

A position indexing plate 13 protrudes from an intermediate portion of the rotating shaft 12 of the index table 11. This position indexing plate 13 is used to determine the angular position when the index table 11 is rotated by a predetermined angle and fixed at that position, and is provided integrally with the rotation shaft 12 and is formed into a circular shape in plan view. ing. As shown in FIG. 2, a plurality of movable guide portions 16 are formed on the outer circumference of the position indexing plate 13. As shown in FIG. This movable guide part 16 guides the fitting and crimping of the engaging member 15, which will be described later, when fixing the position of the index table 11, and has an opening groove part that opens outward as shown in FIG. As shown in FIG.
For example, the number of index positions is formed into four equal parts, six equal parts, or an integral multiple thereof. here,
The reason why the opening angle is set to be 45 degrees or less is that when a lifting load occurs on the position indexing plate 13, if the opening angle is as small as 45 degrees or less, the engaging member 1
5 rotates and rises due to the frictional force generated in the fixed side guide part 17 and the rotational force generated in the movable side guide part 16, and at this time, it becomes stuck to this fixed side guide part 17, so that it has a self-locking function. This is because it becomes stronger and the degree of uplift becomes smaller.

Next, the operation of the index table positioning device configured as described above will be explained. First, let us determine a certain machining position of the index table 11 with respect to the workpiece.
The figure shows the initial state. Here, position index plate 1
It is assumed that the movable side guide portions 16 are formed at six equal positions of 3, and six positions are determined. In this state, as shown in FIG. 5a, the movable cam portion 24
The cam ridges of the fixed cam portion 25 are not in contact with each other, the crimping member 18 is pushed up by the return spring 32 shown in FIG. 4, and the engaging member 15 is engaged with the outer peripheral edge of the crimping member 13. It rises together with the holding member 23 and leaves above the movable guide part 16 along the fixed guide part 17 . Therefore, the position indexing plate 13 can rotate freely. Therefore, in order to determine the processing position of the next workpiece, for example, as shown in FIG.
Rotate 8. At this time, the disk cam 26 rotates in the direction of arrow H in FIG. 6 due to the rotation of the drive shaft 38. Then, the cam roller 34 provided at a predetermined position of the disc cam 26 also moves in the direction of the arrow H.
While rotating in the direction, it enters the notch 35 formed at the sixth equal position on the circumference of the Geneva plate 33, and the disc cam 26 rotates by 1/3 due to the engagement operation with the notch 35. As a result, the Geneva plate 33 is rotated 1/6 in the direction of arrow I. As a result, the position indexing plate 13 rotates by 1/6 along with the Geneva plate 33, thereby moving the index table 11 to the next processing position. At this time, one or more of the movable side guide parts 16 and the fixed side guide part 17 of the position indexing plate 13 face each other and match. During this time, the cam roller 27 provided at the base end of the operating lever 28
simply slides on the circumference of the disc cam 26 and does not operate at all.

When the disc cam 26 rotates 1/3 in the direction of the arrow H as described above, the starting end 39 of the disc cam 26 reaches the position of the cam roller 27, and the disc cam 26 further rotates in the direction of the arrow H. By doing so, the cam roller 27 is pushed out in the direction of arrow J. Then, the tip of the operating lever 28 rotates about the fulcrum 40 in the direction of arrow K, pushing out the link 29 in the direction of arrow L. As a result, the actuating arm 30 connected to the tip of the link 29 with a pin 41 is rotated in the direction of arrow M. The actuating arm 30 is connected to the crimp member 18, as shown in FIGS. 4 and 6, and as the actuating arm 30 rotates in the direction of the arrow M, the crimp member 18 moves as shown in FIG.
is moved in the direction of arrow N. Then, the slope of the movable cam part 24 is gradually lowered while sliding on the slope of the fixed cam part 25, and as shown in FIG. When the pressure bonding member 18 comes into contact with the pressure bonding member 18, the pressure bonding member 18 is moved down the most in the direction of the arrow P against the return spring 32. At this time, as shown in FIGS. 1 and 4, the engaging member 15 also descends together with the holding member 23 engaged with the outer peripheral edge of the crimp member 18.
As described above, the movable guide portion 16 and the fixed guide portion 17 are fitted from above into a tapered space formed between one or more pairs of movable guide portions 16 and fixed guide portions 17 that are already matched with each other.

Here, since the opening angle between the fixed side guide part 17 and the movable side guide part 16 is set to be as small as 45 degrees or less, the engagement member 1
By lowering the engagement member 5 and crimping the engagement members 5 to fit together, the engagement member 15 can be deeply engaged, similar to the state in which a wedge is driven between both slopes. The engaging member 1
5 can be securely fixed. At this time, since the opening angle is small, even a small pressing force is effective for lowering the engaging member 15 to fit and press the engagement member 15. By fitting and press-fitting the engaging member 15, the position of the position indexing plate 13 is fixed by the positioning support plate 14, and as a result, the position of the index table 11 is indexed and determined. In such a state, if a lifting load is applied to the state position indexing plate 13, the movable guide portion 1
6 only has an inclined surface that opens upward and inward at an opening angle of 45 degrees or less, and the fixed side guide portion 17 extends vertically in the vertical direction and is formed asymmetrically around the boundary, so that it will not be affected by the above-mentioned lifting load. As the movable side guide section 16 rises, the engagement member 15 tries to slide along the fixed side guide section 17, but since the opening angle of the movable side guide section 16 is as small as 45 degrees or less, the engagement member 15 , due to the frictional force generated in the fixed side guide part 17 and the rotational force generated in the movable side guide part 16, it rises while rotating, and at this time, it becomes in a state where it clings to this fixed side guide part 17, so that the self-locking function is improved. It becomes stronger and the degree of lifting becomes smaller. Furthermore, when the above operations are completed,
The disk cam 26 rotates approximately one revolution, and the terminal end 42 of the cam reaches close to the cam roller 27.

Next, in order to determine the machining position of the next workpiece, move the disc cam 26 from the above state to the arrow H.
Immediately after the rotation in the direction shown in FIG. 6, it returns to the initial state shown in FIG. At this time, since the pushing against the cam roller 27 is released, the actuating arm 30 is returned in the direction of the arrow Q by the biasing force of the coil spring 31. Then, as shown in FIG. 5(b), the crimping member 18 is returned in the direction of the dashed arrow R, and the cam ridges of the movable cam portion 24 are disengaged from the cam ridges of the fixed cam portion 25, and the crimping member 18 is returned as shown in FIG. 4. Due to the biasing force of the return spring 32 interposed on the lower surface side of 18, the slope of both cam parts 24 and 25 moves the arrow R.
As shown in FIG. 5a, the pressure bonding member 18 rises as indicated by a broken line arrow S. At this time, since the engaging member 15 is held from the outer surface and the lower surface by the holding member 23 engaged with the outer peripheral edge of the crimp member 18, the engaging member 15 is engaged by the retaining member 23 that rises together with the crimp member 18. The lower surface of the member 15 is pushed up, and the fixed side guide part 1
7 above the movable guide portion 16.
This allows the position indexing plate 13 to rotate freely, making it possible to index the next position.

Furthermore, only the movable side guide part 16 has an inclined surface that opens upward and inward at an opening angle of 45 degrees or less, and the fixed side guide part 17 extends vertically in the vertical direction and is formed asymmetrically with respect to the boundary thereof. Therefore, when a lifting load is applied to the position indexing plate 13,
As the movable side guide section 16 rises, the engagement member 15 tries to slide along the fixed side guide section 17, but since the opening angle of the movable side guide section 16 is as small as 45 degrees or less, the engagement member 15 , due to the frictional force generated in the fixed side guide part 17 and the rotational force generated in the movable side guide part 16, it rises while rotating, and at this time, it becomes in a state where it clings to this fixed side guide part 17, so that the self-locking function is improved. It becomes stronger and the degree of lifting becomes smaller. From this, the engaging member 15
is held by the interaction between the guide portions 16 and 17, and does not slip out from between the guide portions 16 and 17, thereby ensuring correct positioning.
