Description

[Detailed explanation of the invention] [Industrial application field] This invention is applicable to machining centers, NC milling machines,
This relates to a universal multi-axis indexing device used in NC drilling machines, etc.

[Prior art] In indexing processing, positioning is often performed continuously (arbitrary angle indexing) or discontinuously (finite angle indexing), but continuous and discrete positioning can be performed by controlling with one machine. There is no indexing device that performs both continuous and continuous indexing operations.

On the other hand, the discontinuously-dedicated indexing device has a high angular accuracy but has the disadvantage that it cannot perform continuous indexing.

[Problem that the invention attempts to solve]

The present invention has solved these problems, and is an indexing device with a simple structure and low cost.It has the function of continuous indexing and discontinuous indexing. A versatile multi-axis indexing device that can perform multi-axis indexing around the X-axis by lining up multiple units in a direction, and also enables multi-faceted processing of the workpiece by indexing these parallel indexing tables around the Y-axis. provide.

[Means for solving problems]

An indexing table 3 to which a workpiece 2 is attached is provided on the front surface of the casing 1, and an indexing rotation shaft 4 of the indexing table 3 is supported at the front of the casing 1 and faces inside the casing 1. 4
A worm wheel 5 is provided in the worm wheel 5, and a worm 6 is meshed with the indexing table a, and a discontinuous indexing table 3 is removably attached to the indexing table a to discontinuously index and position the indexing table 3. An indexing fixing device b, a continuous indexing fixing device c which is also detachably attached to the indexing table a and continuously indexing and positioning the indexing table 3, and a driving device d which drives the indexing table a. Either one of the discontinuous indexing fixing device b or the continuous indexing fixing device c is selected and attached to the indexing table a, and a plurality of such indexing tables a are arranged in parallel, and this indexing table a are connected by a joint 7, and a driving device d is provided on the indexing table a on one side.

[Effect]

If the discontinuous indexing fixing device b is attached to the indexing table a, continuous indexing around the X axis can be performed.

Similarly, if a continuous indexing fixing device c is attached to the indexing table a, continuous indexing around the X axis can be performed.

When a plurality of indexing tables a are arranged in parallel and connected by a joint 7, it becomes multi-axial, and a plurality of workpieces 2 can be indexed continuously or discontinuously around the X-axis.

As shown in FIG.
One support part 8a of the underframe 8 is rotatably provided on the support base 9, and a drive device d is provided on the outside of the support base 9, and discontinuous index fixation is provided on the other support part 8b. Indexing around the Y-axis can be performed by fixing the indexing base a to which the device b or continuous indexing fixing device c is attached and rotating the base frame 8.

〔Example〕

The discontinuous index fixing device b includes a piston 11 provided in a casing 10, an engagement disk 12 that is slidably inserted into an index rotation shaft 4 protruding from the front surface of the piston 11, and this engagement disk. Engagement teeth 13 of the same number as the index number formed radially on the front surface of 12,
Engagement teeth 1 are fitted into the index rotation shaft 4 corresponding to the engagement disc 12 with engagement teeth 13 in a non-rotating state.
4, and an engagement recess 17 that engages with an engagement protrusion 16 on the rear surface of the casing 1 of the indexing base a provided on the front surface of the piston 11.

The continuous index fixing device c includes a piston 19 provided in a casing 18, an engagement disk 20 that is slidably inserted into the index rotation shaft 4 protruding from the front surface of the piston 19, and this engagement disk. Brake disc 21 provided on the front of 20 and this brake disc 21
The engagement rotary disk 23 includes a brake disk 22 that is fitted into the index rotary shaft 4 in a non-rotating manner and is pressed into contact with the index rotary shaft 4 in accordance with the above.

[Effect of idea]

Since the present invention is configured as described above, it has the following features.

1 Discontinuous indexing is possible by combining the indexing table a and the discontinuous indexing fixing device b.

2. Continuous indexing is possible by combining the indexing table a and the continuous indexing fixing device c.

3. By arranging a plurality of indexing tables a in parallel and connecting them through joints 7, it is possible to index a plurality of workpieces 2 at the same time, that is, to perform multi-axis indexing around the X-axis.

4 As shown in FIG. 5, a plurality of indexing tables a are arranged side by side on an underframe 8, and a discontinuous indexing fixing device b or a continuous indexing fixing device c is attached to one support part 8b of the underframe 8. By providing an indexing stand a, the underframe 8
is rotated around the Y axis to perform X axis indexing and at the same time
Axis indexing can be performed.

5 As described above, the present invention enables continuous indexing, discontinuous indexing, and simultaneous multi-axis indexing by replacing the units of discontinuous fixing device b and continuous fixing device c with one indexing device. In addition, depending on the combination, it has excellent practical effects such as being able to perform multi-axis indexing such as X-axis and Y-axis indexing.
