  The present invention relates to a rotating device and a method for mounting a distributor in the rotating device.

  For example, Patent Document 1 describes a machine tool including a turning spindle device (rotating device). The turning main spindle device includes a fixed main body portion that is rotatably supported in a state in which the turning shaft is inclined at 45 degrees, a turning main body portion that is rotatable together with the turning shaft, and a main shaft that is supported by the turning main body portion around the turning shaft. Device. The turning spindle device turns the spindle device around the turning axis to perform turning indexing between the vertical posture and the horizontal posture.

  In general, when a fluid is supplied to the main spindle device or the like, a fluid distributor (also referred to as a multi-port rotary joint, hereinafter simply referred to as “distributor”) is often used in the turning main spindle device. The distributor includes a fixed sleeve and a rotary sleeve each provided with a plurality of ports, and is arranged coaxially with the rotary axis of the rotary shaft in the fixed main body, and is provided with a sliding rotary seal provided between the fixed sleeve and the rotary sleeve. Seal the fluid in each port.

  The rotary seal is inserted into the fixed sleeve with an interference fit and is held by the rotary sleeve. When such a rotary seal deteriorates or breaks, fluid leakage occurs. Therefore, the operator removes the rotary sleeve together with the rotary seal from the fixed sleeve and replaces the rotary seal. However, since the sliding resistance between the fixed sleeve and the rotary seal is large, it is not easy to replace the seal in the turning spindle device mounted on the machine tool.

  Patent Document 2 describes a table including a turning shaft and a distributor. This table has a structure in which the fixed sleeve and the rotating sleeve of the distributor can be pulled out of the table in an integrated state. Therefore, since the operator can separate the fixed sleeve and the rotating sleeve outside the table, the seal replacement operation can be easily performed.

An electric wiring path 29 that conducts electricity to the spindle device 30 is provided inside the fixed main body portion 23. That is, the electrical wiring path 29 is provided so as to reach the inside of the turning main body 22 from the inside of the fixed main body 23 through the guide 50 inserted into the center hole 25 e of the fixed sleeve 25. As will be described in detail later, the guide 50 gently bends the electric wiring path 29 by guiding the electric wiring path 29 following the rotation of the turning main body 22. Thereby, the fracture | rupture and damage of the electrical wiring path 29 can be prevented.

  The pivot shaft main body 21A is supported in the fixed main body 23 so as to be rotationally driven by a motor and a speed reduction mechanism (not shown). The distributor 21B is disposed coaxially with the turning axis D in the center hole of the turning shaft main body 21A.

An internal thread 24d is provided in which a phase fixing bolt 28 having a predetermined depth can be screwed in the direction.

(2. Guide structure)
The guide 50 is a member that guides the electric wiring path 29 so as not to be twisted beyond a predetermined allowable range due to the turning motion of the turning spindle device 20. The guide 50 includes a plurality of annular link members 51. As shown in FIGS. 4A and 4B, the link member 51 is formed in a shape in which the small diameter portion 52 and the large diameter portion 53 are integrated with a coaxial step.

  The outer diameter of the small diameter portion 52 is formed slightly smaller than the inner diameter of the large diameter portion 53. On the outer periphery of the small diameter portion 52, a pin 54 is detachably provided. On the outer periphery of the large-diameter portion 53, a through-groove portion 55 extending in the circumferential direction with a width slightly larger than the outer diameter of the pin 54 is formed. On the inner periphery of the small-diameter portion 52 and the large-diameter portion 53, partition plates 56 are formed so as to extend in the axial direction at intervals of 90 degrees in the circumferential direction. That is, the link member 51 is formed with four regions A1 to A4 in the circumferential direction.

  As shown in FIG. 5A, the plurality of link members 51 are arranged so that the centers thereof are aligned on the same line and the outer periphery of the small diameter portion 52 is slidably fitted into the inner periphery of the large diameter portion 53 of the adjacent link members 51. Is done. Each link member 51 is attached by being inserted with the pin 54 inserted into the groove portion 55 and integrally connected thereto. When the inner periphery of the large-diameter portion 53 of one link member 51 rotates along the outer periphery of the small-diameter portion 52 of the adjacent link member 51, the pin 54 slides along the groove portion 55 in the groove portion 55. Thereby, one link member 51 can be rotated by an angle corresponding to the distance that the pin 54 slides from one end of the groove portion 55 to the other end, that is, restricted to a predetermined angle.

  As shown in FIG. 3, the guide 50 is inserted into the center hole 25 e of the fixed sleeve 25. The lower end link member 51 is bolted to the rotary sleeve 24 via the flange 24f, and the upper end link member 51 is bolted to the fixed sleeve 25 via the flange 25f. And each area | region A1-A4 of the guide 50 becomes a shape which carried out the shape communicated linearly, ie, the cylindrical shape, divided into 4 in the axial direction. The electric wiring path 29 is passed through each region A1-A4.

  In the guide 50, when the turning main body 22 rotates around the turning axis D together with the rotating sleeve 24, first, the link member 51 at the lower end of FIG. 3 rotates around the turning axis D together with the rotating sleeve 24. The link member 51 at the lower end rotates until the pin 54 moves from one end side (the lower end side of the groove portion 55 shown in FIG. 5A) of the groove portion 55 and contacts the other end side (the upper end side of the groove portion 55 shown in FIG. 5A). To do.

  Next, in the guide 50, the upper link member 51 adjacent to the lower link member 51 in FIG. 3 rotates around the turning axis D. In this adjacent upper link member 51, the pin 54 moves from one end side of the groove portion 55 (the lower end side of the groove portion 55 shown in FIG. 5A) and contacts the other end side (the upper end side of the groove portion 55 shown in FIG. 5A). Rotate until. In this manner, the guide 50 sequentially rotates from the lower link member 51 in FIG. 3 toward the upper link member 51. And finally, when rotation of all the link members 51 is completed, each pin 54 will be in the state which contact | abutted to the other end side (upper end side of the groove part 55 shown to FIG. 5B).

  And each area | region A1-A4 of the guide 50 is shifted | deviated gradually with the rotation of each link member 51, and becomes helical. Since the electrical wiring path 29 is bent by the partition plate 56 so as to draw a gentle spiral, the electrical wiring path 29 corresponds to the spiral displacement operation of the respective regions A1 to A4 of the guide 50. There is no risk of breakage or breakage.

(3. Distributor installation / removal work in the rotating spindle device)
Next, the attaching / detaching operation of the distributor 21B when the rotating seal S of the distributor 21B is replaced in the turning spindle device 20 will be described with reference to the drawings. First, the operator drives the motor of the turning shaft main body 21A to rotate the turning main body portion 22 to turn the main spindle device 30 to change the attitude of the main spindle device 30 (direction of the rotation axis R) in the horizontal direction (0 degree). (Step S1 in FIG. 6). Thereby, the rotation sleeve 24 and the fixed sleeve 25 of the distributor 21B are in a state in which the rotation phases are matched.

  The operator opens the door 23 a of the fixed main body 23 and removes the guide 50 and the electric wiring path 29. Then, the phase fixing bolt 28 (fastening means) is inserted into the hole 25d of the flange 25a of the fixing sleeve 25, screwed into the female screw 24d (fastening means) of the rotating sleeve 24, and fastened, and the rotational phase is adjusted. The rotating sleeve 24 and the fixed sleeve 25 in a state are positioned and fixed (step S2 in FIG. 6, pre-connection step). Then, as shown in FIG. 7, the second fixing bolt 27 fastened to the flange 25 a of the fixed sleeve 25 is removed from the fixed main body portion 23, the door 22 a of the swiveling main body portion 22 is opened, and the rotary sleeve 24 is fastened. The first fixing bolt 26 is removed from the pivot shaft main body 21A (step S3 in FIG. 6, removal step).

  As shown in FIG. 8, the operator pulls out the rotating sleeve 24 and the fixing sleeve 25 integrally connected by the phase fixing bolt 28 from the pivot shaft main body 21 </ b> A (step S <b> 4 in FIG. 6). Take it out. Then, the phase fixing bolt 28 is removed to separate the rotating sleeve 24 and the fixing sleeve 25 (step S5 in FIG. 6), the rotating seal S is replaced, that is, the rotating seal S is extracted from the fixing sleeve 25, and a new rotating seal S is obtained. Is inserted into the fixing sleeve 25 (step S6 in FIG. 6).

  Since the guide 50 for passing the electric wiring path 29 is inserted into the center hole 25e of the fixed sleeve 25, the fixed sleeve 25 tends to have a large diameter. For this reason, the sliding resistance between the fixed sleeve 25 and the rotary seal S is large, and it is not easy to replace the rotary seal S by removing the rotary sleeve 24 from the fixed sleeve 25 together with the rotary seal S in the turning spindle device 20. However, as described above, the rotary sleeve 24 and the fixed sleeve 25 that are integrally connected by the phase fixing bolt 28 can be extracted from the pivot shaft main body 21A, so that the rotary sleeve 24 and the fixed sleeve 25 are outside the fixed main body portion 23. And the replacement work of the rotary seal S becomes easy.

  Then, the operator inserts the fixing sleeve 25 into the rotating sleeve 24, inserts the phase fixing bolt 28 into the hole 25d of the flange 25a of the fixing sleeve 25, and is screwed into the female screw 24d of the rotating sleeve 24 and fastened ( Step S7 in FIG. 6, connecting step). As a result, the port 25b of the fixed sleeve 25 and the port 24b of the rotary sleeve 24 can be made to coincide with each other, so that the work of matching the rotational phases of the fixed sleeve 25 and the rotary sleeve 24 can be eliminated, and the number of work steps can be reduced. Reduction can be achieved.

  Then, the rotating sleeve 24 and the fixing sleeve 25 integrally connected by the phase fixing bolt 28 are carried into the turning shaft main body 21A and inserted into the turning shaft main body 21A (step S8 in FIG. 6, insertion process). Then, the second fixing bolt 27 is screwed and fastened to the fixing main body portion 23 through the flange 25a of the fixing sleeve 25, and the first fixing bolt 26 is screwed through the rotating sleeve 24 and fastened to the turning shaft main body 21A. (Step S9 in FIG. 6, attachment process).

  The operator removes the phase fixing bolt 28 (step S10 in FIG. 6, connection release step), closes the door 23a of the fixed main body 23 and the door 22a of the swiveling main body 22, and completes all the operations. As a result, the rotating sleeve 24 and the fixed sleeve 25 are in the same state as before being extracted from the pivot shaft main body 21A, and therefore the rotational phases are matched so that the corresponding ports 24b, 25b are matched. become.

(4. Other)
In the embodiment described above, the case where the distributor 21B is applied to the turning spindle device 20 having the inclined turning shaft 21 has been described. However, the turning spindle device having a horizontal turning axis and the turning spindle device having a vertical turning axis are also applicable. The same applies.
Further, the turning spindle device 20 in which the turning axis D of the turning shaft 21 is inclined 45 degrees with respect to the Z axis has been described, but the same applies to the turning spindle device in which the turning axis D of the turning axis is inclined at an arbitrary angle with respect to the Z axis.

As a result, the wiring path 29 is not locally abruptly twisted, and there is no possibility of breakage or breakage.

  Further, the fixing sleeve 25 and the rotating sleeve 24 are incorporated in the rotating device 20, and the fastening means (the phase fixing bolt 28 and the female screw 24d) are in a state where the ports of the fixing sleeve 25 and the ports of the rotating sleeve 24 coincide with each other. Thus, the structure can be connected integrally. The port of the fixed sleeve 25 and the port of the rotary sleeve 24 can be integrally connected by simple means so as to coincide with each other.

  Further, in the above-described rotating device (slewing spindle device 20), the distributor 21B is mounted, and the fixed sleeve 25 and the rotating sleeve 24 extracted from the fixed body 23 are connected to the port 25b of the fixing sleeve 25 and the port 24b of the rotating sleeve 24. , A connecting step for integrally connecting them so that they match, an inserting step for inserting the integrally connected fixed sleeve 25 and rotating sleeve 24 into the fixed body 23, and a fixing sleeve 25 and rotating sleeve 24 inserted into the fixed body 23.
