[Structure] In a rotary joint type index table in which a spindle 2 is rotatably provided in a frame 1, a table 3 is fixed to an upper portion of the spindle 2, and a distributor 4 is provided in the spindle 2, a fluid is distributed to the distributor 4. A thin manifold block 6 provided with a supply passage 9 is detachably provided on the lower surface of the frame 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an index table having a rotary joint.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, for example, an index table as disclosed in Japanese Utility Model Laid-Open No. 2-51041 has been proposed.

However, the invention according to Japanese Utility Model Laid-Open No. 2-51041 discloses an oil supply unit having a passage connected to an oil supply unit (hydraulic unit) for supplying oil to the distributor incorporated in the frame. -Since the distributor communication part is fixedly installed in the frame, the position of the oil supply part with respect to the frame cannot be set to an arbitrary position.

Further, in the index table disclosed as a conventional example of Japanese Utility Model Laid-Open No. 2-51041, when the index table is fixedly mounted on the mounting table, since the distributor largely projects downward from the lower surface of the frame. In addition, there is a drawback that the mounting table becomes an obstacle and the piping work of the distributor is troublesome, and this type has a protruding distributor, so if the index table is used horizontally, the distributor will be very disturbing. However, there is a drawback that the entire device cannot be made compact. Further, this type also has a drawback in this point in that when it is used horizontally, it is necessary to change the motor mounting position.

The present invention has a technical object to provide an index table that solves such a drawback.

[0006]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

In a rotary joint type index table in which a spindle 2 is rotatably provided in a frame 1, a table 3 is fixed to an upper portion of the spindle 2, and a distributor 4 is provided in the spindle 2, a fluid is distributed to a distributor 4 The present invention relates to an index table characterized in that a thin manifold block 6 having a passage 9 for supplying air is detachably attached to the lower surface of the frame 1.

[0008]

[Action]

 By changing the arrangement direction of the manifold block 6 detachably provided on the lower surface of the frame 1 with respect to the frame 1, the arrangement position of the passage 9 with respect to the frame 1 can be arbitrarily changed.

[0009]

【Example】

 The drawings are one embodiment of the present invention and will be described below.

Reference numeral 1 is a frame. Further, 2 is a spindle, which is rotatably provided with respect to the frame 1 by a bearing 7. A circular table 3 is fixed to the upper portion of the spindle 2 with bolts 8.

Reference numeral 4 denotes a distributor, which is connected to the spindle 2 by a rotary joint method. Reference numeral 6 denotes a manifold block attached to the lower end of the distributor 4, a passage 9 communicating with the passage 18 of the distributor 4 is provided inside, and an oil feeding pipe 5 is connected to the end of the passage 9. An oil supply unit (hydraulic unit) is connected to the end of the oil feed pipe 5. The manifold block 6 is sized so as to be housed in a space 16 formed by a projecting support portion 15 of an index table mounting table 14, which will be described later. The means for attaching the manifold block 6 to the frame 1 may be means such as bolts.

Reference numeral 14 denotes an index table mounting table, which supports the index table by a protruding support portion 15.

Reference numeral 10 is a block body provided with a fluid outlet 11, reference numeral 12 is a worm / worm wheel portion for rotating the table 3, reference numeral 13 is a center cap, and reference numeral 17 is a servo motor which serves as a drive portion for the worm / worm wheel portion. Is.

Since the present embodiment has the above-described configuration, the manifold block 6 is fixed to the frame 1 at an arbitrary position, and oil is supplied from the hydraulic unit to the passage 9 of the manifold block 6 via the oil feed pipe 5. By introducing and sending out from the fluid outlet portion 11 of the block body 10, it is possible to perform an appropriate work, for example, a work holding work by a clamp.

As described above, according to this embodiment, since the manifold block 6 is detachably attached to the frame 1, the hydraulic unit can be installed at an arbitrary position with respect to the frame 1, and accordingly, from an arbitrary position. Oil can be sent to the distributor 4, and by removing the manifold block 6 from the frame 1, maintenance of the passage 9 and the passage 18 of the distributor 4 can be performed well.

Further, since the manifold block 6 is thin and is housed in the space 16, the whole apparatus becomes very compact. For example, even if the index table is used in a horizontal position, Unlike the conventional example, the distributor is not in a protruding state, and this is a very easy-to-use device.

[0017]

[Effect of the device]

 Since the present invention is constructed as described above, the index table is very easy to use, compact, and simple in structure.
