[Prior Art] The indexing table is a type of rotary indexing table with a mounting surface for each of the additional mounting units, and multiple workpieces are installed at the same time to shorten the time required for the industry. Because of 16, the waiting time of the working machine can be shortened. In the rotary indexing table described in the mechanism trr1, a direct drive motor that is driven in the frame is used. The drive side machining table is fixed to the rotor of the direct drive motor that is the source of the spurs by the 201107072 screw, and the driven side machining table is driven by the drive/'s side machining table. In detail, at the end of the side of the direct drive motor & __ rpm, the drive side processing table is fixed by screws with the sub-coaxial, that is, with the rotor and the common axis, and is fixed by screws. On the drive side processing table, the connection shaft is coaxially disposed on the same. The connecting shaft is disposed in the direct drive motor of the vehicle according to + ^ , ° ° in the direction of the bullish direction and extends in the axial direction to reach the rotor and the other end of the connecting shaft of the other side of the rotor is coaxial with the connecting shaft The driven side processing table is fixed by screws. Thereby, the two processing stages are respectively disposed on both sides of the direct drive motor via the direct drive motor, and the driven side processing table is coupled to the rotor via the drive side processing table and the connecting shaft. [PRIOR ART DOCUMENT] [Patent Document 1] Japanese Patent Application Laid-Open No. Hei. No. Hei. No. Hei. No. 5, No. 5, No. 631, the rotary indexing table t described in Patent Document 1 is applied from the end portion of the rotor to the driving side. The rotational force of the table is transmitted to the driven side processing table through the connecting shaft. However, since the connecting shaft has a long size, distortion is likely to occur. Therefore, in the case where the workpiece is a heavy object, the degree of distortion of the joint shaft becomes large' and the degree of distortion of the joint shaft differs according to each index angle when the workpiece is eccentric with respect to the axis of the processing table. Therefore, in terms of the accuracy of the index angle from the reference position of the processing table, the driven side processing table has to be inferior to the driving side processing table. Therefore, the machining accuracy of the workpiece mounted on the processing table on the driven side is deteriorated. Therefore, in addition to the deterioration of the machining accuracy of a part of the workpiece, the machining accuracy is deviated between the workpieces, and the quality is generated.

In view of the above problems in the prior art, the object of the present invention is to prevent the machining accuracy of a part of the workpiece from being lowered and to avoid machining between the workpieces on the rotary indexing table in which the direct drive motor is incorporated and the two processing tables are disposed via the motor. Deviations in accuracy to maintain the quality of the workpiece. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the prior art. The rotary indexing table of the first aspect of the present invention includes: a direct drive motor having a rotor and a stator; and a second processing table, which is disposed between the direct drive motor and the direct drive motor; The frame has a built-in direct drive motor' and the second and second processing tables are rotatably supported around the common axis of the rotor. The technical point is that the second machining port is connected to the inner side of the stator in the radial direction. The opposite of the rotor. A rotary indexing table according to a second aspect of the present invention is the rotary indexing table according to the first aspect of the invention, wherein the second and second processing stages and the cutter have through holes having the axial depths thereof as the common axis. . In the rotary indexing table according to the third aspect of the present invention, the first detent device for the first processing station and the second deactivating device for the second processing table are provided in the rotary indexing table of the first or second aspect. The lost device is held in the second division and the two clamping devices are operated to hold the processing stations relative to the frame: none of the first and second processing stations are respectively connected to the knuckle of the 201107072 That is, the closer end of the two ends of the rotor, so that in terms of the accuracy of the indexing angle from the reference position, one process can be prevented from being worse than the other. Therefore, in addition to avoiding a decrease in the machining accuracy of a part of the workpiece, it is also possible to avoid a deviation in the machining accuracy between the workpieces. Further, since the first and second processing stages and the rotor each have a through hole having the axis thereof as the common axis, the workpiece can be inserted into the through hole and the long X piece can be processed. At this time, the workpiece can be held by the two processing stages, and since the workpiece is held at two places separated from each other, even if it is a long size, it is not shaken and the precision is maintained for processing. In the conventional rotary indexing table of the prior art, the through-hole is provided in the connecting shaft for inserting a long-sized workpiece. By passing one end of the long-sized workpiece through the through 1 of the connecting shaft, the two processing stations can be used to hold the long-sized workpiece. However, @, in the case of the prior art rotary indexing table, the maximum diameter of the workpiece is determined by the through diameter of the connecting shaft. / Since the connecting shaft is disposed in the half (four) of the direct (four) motor, the outer diameter becomes a very small diameter and the through hole has to be made into a very small diameter. The maximum diameter of the long workpiece that can be processed is limited. On the other hand, it is conceivable to increase the straightness of the through-hole to increase the maximum diameter of the workable long-sized workpiece, in which case it is necessary to increase the outer diameter of the joint shaft. However, the direct drive motor disposed on the outer side in the radial direction of the connecting shaft must be enlarged in size with the large k-connection of the connecting shaft, so that the rotary indexing table frame incorporating the direct drive motor must not be required to directly drive the horse in the rotating point of the present invention. In the case of the degree table, the inner side of the radial direction of the 201107072 is connected (4), and the maximum diameter that can be processed of the long-sized guard member can be set such that only the wall thickness portion of the connecting shaft is larger than the rotary indexing table of the prior art. In other words, t' does not increase the size of the direct drive motor, but expands the range of applications for long workpieces that can be machined. Further, the first holding device for the i-th processing table and the second device are provided during the indexing processing of the workpiece by the i-th holding device for the first processing table and the second decoupling device for the second processing table. Since the second clamping|position of the processing table is operated in common, (4) the holding table of the holding member is firmly held so as not to be rotatable, and the wire is held at an indexing angle of the pre-twisting. Specifically, since the boring processing table and the second processing table are integrally connected by the rotor, the holding force generated by the second holding device and the second clamping device are generated during the indexing of the workpiece. Retention: acting on the processing table that holds the workpiece, the processing table that holds the workpiece is firmly held by the two retaining forces to be unable to rotate 'and can avoid the rotation from the predetermined indexing angle by the machining force applied to the workpiece Case.

The rotor 8 includes a driving portion 8n, a τ u first holding portion 8b, and a second holding portion 8c which are disposed on the inner side in the +diameter direction of the stator 7 and whose outer peripheral surface portion is opposed to the stator 7. The driving portion 8d is formed in a hollow shape, and has a through hole 8da coaxial with the outer peripheral surface portion thereof. Further, the driving unit Μ includes a hollow cylindrical core P and a plurality of magnets (not shown) that are fixedly attached to the outer peripheral surface portion of the core and arranged in the circumferential direction. The second holding portion 8b is disposed at an end portion on the first processing table 12 side of the driving portion, and is integrally formed by the screw 25 with respect to the core portion. The first processing table 12 side end portion of the rotor 8 is configured. . In addition, the second holding portion 8c is disposed at the end on the second processing table 13 side of the driving portion 8d, and is integrally fixed to the core portion by the screw 25, thereby constituting the second processing table 13 side end of the rotor 8. unit. The first holding portion 8b has a sleeve 8bb fitted in the through hole 8da of the driving portion 8d, a bearing fitting shaft portion into which the inner ring of the tapered roller bearing 14 is fitted, and a through fitting in the first processing table 12 In addition to this, the sleeve 8bc of the hole 12a has a through hole 8ba that matches the shaft center and the bearing fitting portion, and is formed in a hollow round shape. Further, in the first holding portion 8b, each outer peripheral surface portion of the sleeve 8bb and the sleeve gbc 201107072 is formed coaxially with the bearing fitting shaft portion. The second holding portion 8c has a sleeve fitting portion 8cb' fitted in the through hole 8da of the driving portion 8d, and a bearing fitting shaft portion into which the inner ring of the tapered roller bearing 14 is fitted, and a through fitting of the second processing table 13 In addition to this, the sleeve 8cc of the hole 13a has a through hole 8ca that matches the shaft center and the bearing fitting portion, and is formed in a hollow cylindrical shape. Further, in the second holding portion 8c, each outer peripheral surface portion of the sleeve 8cb and the sleeve 8CC is formed coaxially with the bearing fitting shaft portion. With these configurations, in the state in which the sleeves 8bb and 8cb of the first holding portion 8b and the second holding portion 8c are fitted to both end portions of the through hole 8da of the driving portion 8d, the driving portion is driven. 8d, the first holding portion 8b and the second holding portion 4 8 c are combined in a state in which their respective axes coincide. Further, the bearing fitting shaft portion of the first holding portion 8b and the bearing fitting shaft portion of the second holding portion 8c are supported by the pair of circular roller bearings 14, and the pair of tapered roller bearings 丨4 are as described above. The axis is coaxially supported with the axis 2 of the through hole of the frame 65, so that the rotor 8 is in a state where the axis is aligned with the axis 2 of the through hole, that is, the axis 2 is The crucible is rotatably supported relative to the frame 65 as a center of rotation. Further, in the case of this configuration, since the through hole of the frame 65 coincides with the axis of the rotor 8, the axis 2〇 becomes a common axis. The first processing table 12 has a cylindrical main body portion that is inserted into the through hole of the clamp frame 5, and a sleeve that is formed to be aligned with the main body portion and that is fitted to the first holding portion 8b of the rotor 8 Through hole 12a. Further, the machining table 12 is fixed by the screw 23 with respect to the end surface of the second holding portion 8b, and I is connected to the corresponding end of the rotor 8, specifically, the most 10 of the rotor 8 201107072. The ends, that is, the closer ends of the two ends of the rotor 8. As described above, in the first holding portion 8b, the outer peripheral surface portion of the sleeve 8bc fitted to the through hole 12a of the first processing table 12 is formed coaxially with the bearing fitting shaft portion. That is, the outer peripheral surface portion of the sleeve 8bc is formed coaxially with the rotor 8. Therefore, in the through hole 12a formed coaxially with the main body portion, the i-th processing table 12 fitted to the sleeve 8bc and fixed to the i-th holding portion 8b is such that the through hole i2a and the axis of the main body portion are connected to the rotor 8 In the state of this, it is supported by the rotor 8. Thus, the first processing table 12 passes through the rotor 8 and the tapered roller bearing 14 around the axis of the rotor 8, that is, around the common axis 2〇, in other words, the common axis 20 as a center of rotation. It is rotatably supported by the frame 65. In addition, the first processing table 12 has an end portion on the opposite side to the end portion of the sleeve 8b to which the first holding portion 8b is fitted, that is, the end portion of the first processing table 12 and the through hole 12a. The common axis 2〇 is orthogonal to the workpiece mounting surface 12b. In the second processing, a cylindrical main body portion that is inserted into the insertion hole of the clamp frame 6 and a sleeve that is formed so that the axis is aligned with the main body portion and that is fitted to the second holding portion 8c of the rotor 8 are processed. Further, the second processing stage [3] is the same as the first processing stage 12, and is connected to the corresponding end of the rotor 8, that is, the closer end of the both ends of the rotor 8. As described above, the outer peripheral surface portion of the sleeve 8cc that is fitted into the through hole 13a of the second processing table 13 in the second holding portion 8c is formed coaxially with the bearing fitting shaft portion. That is, the outer peripheral surface portion of the sleeve 8 cc is formed coaxially with the rotor 8. Therefore, in the through hole 13a formed coaxially with the main body portion, the second processing table 13 that is fitted to the cover 11 201107072 and is fixed to the second holding portion 8c is such that the through hole 13a and the axis of the main body portion are connected to the rotor. It is supported by the rotor 8 in the state of 8_. Thus, the second processing table 13 is the same as the i-th processing table 12, and the rotor 8 and the tapered roller bearing 14' are arranged around the common axis 2〇, in other words, the common axis 20 as a center of rotation. The frame 65 is rotatably supported. Further, the second processing table 3 has a workpiece mounting surface 13b orthogonal to the above-described common axis 20 at the outer end portion. The two workpiece mounting faces 、 and ribs are orthogonal to the above-described common axis 2〇 as described above, and therefore are disposed in parallel with each other. The two tapered roller bearings 14 are arranged opposite each other. Specifically, the two tapered roller bearings 14 are arranged opposite to each other so as to be restricted from the shoulder surface of the frame 65 so as to be displaced toward the inner side in the axial direction of the outer ring, that is, on the side of the first processing table 12 In the case of the tapered roller bearing 14 , the axial roller is displaced in the direction toward the second machining table 13 , and in the case of the tapered roller bearing 14 disposed on the second machining table 13 side, the approach is closer to the machining table η. The direction of the axis is displaced. Further, the two tapered roller bearings 14 are formed by a gasket 34 inserted between the inner ring and the machining table 12, and a ring formed by the bearing fitting shaft portion of the second holding portion 8c. The threaded lock nut 17 restricts the displacement toward the outer side in the axial direction as follows, that is, in the case of the tapered roller bearing 14 disposed on the first processing table 12 side. The displacement in the axial direction away from the direction of the second processing table 13 is shifted in the axial direction away from the direction of the "Moutine: 1 2" in the case of the tapered roller bearing disposed on the side of the month = table 13 . σ The two tapered roller bearings 14 are appropriately biased in the axial direction by adjusting the thickness a of the spacer 34 or the position of the locking screw 12 201107072 - the axial direction of the female 17 . By imparting a proper preload to the tapered roller bearing 14, the rotational performance of the tapered roller bearing 14 is not impaired, and the movement of the machining tables 12, 13 in the axial direction is eliminated. Therefore, the machining tables 12 and 13 are prevented from being displaced in the axial direction due to the machining force from the tool, and the machining accuracy of the workpiece is maintained. According to the above, the rotor 8 and the first and second machining tables 12 and 13 constitute a rotating portion of the rotary indexing table 60, and are rotatable by the two tapered roller bearings 14 around the common axis 2〇. Supported on the frame 65. Further, the rotor 8 and the first and second processing stages 12 and 13 have through holes 8ba, 8Ca, 8da, 12a, and 13a that are coaxial with each other, and the long workpieces are inserted into the through holes 8ba, 8ca, 8da, and 12a, 13a, and the two processing stations 12, 13 can be used to hold the long workpiece. The rotary indexing table 60 holds the long-sized workpiece at two positions separated in the axial direction, thereby suppressing the shaking of the long-sized workpiece and achieving high-precision machining. Further, since the axes of the through holes 1 2a and 13a of the i-th and second processing stages 12 and 13 are the common axis 2〇, the ruins are provided on the workpiece mounting faces 12b and 13b of the processing tables 12 and 13. The reference 'in the case of the workpiece holding jig' can be used through the through holes 2a, 13a. The rotary indexing table 6A of the present embodiment includes a first holding device 62 for the i-th processing table 12 and a second holding device 63 for the second processing table 12, and two of the second holding devices 63 for the second processing table 12 The clamping devices 62, 63 operate simultaneously. Hereinafter, the holding devices 62 and 63 will be described in detail. The base frame 2 is provided with a passage 2a that is open on the outer side, and the passage is on the first side. The side of the framed wood 3 and the side of the second side frame 4 are branched and connected to each other. Further, the passage 3a placed on the side frame 3 and the passage 3a of the first side frame 3 provided on the side frame 4 are fitted in a hole for fitting the sleeve of the frame 5. The opening is open and connected to the annular groove 5a of the outer peripheral surface of the sleeve of the clamp frame 5. Further, the passage of the second side frame 4 is opened in a fitting hole portion into which the sleeve of the clamp frame 6 is fitted, and is connected to the annular groove 6a provided on the outer circumferential surface of the sleeve of the cool frame 6. The sleeves of the holding frames 5, 6 are thinned in the radial direction at the portions of the annular grooves 5a, 63, and therefore, the operating fluid is connected to the tube of the passage 2a through the connector 18 provided on the outer side surface of the base frame 2. 19 is supplied to the annular grooves 53 and 6a via the passages h, 3a, and 4a. When the fluid pressure acts on the annular groove and the Lu 6a, the thin portions of the annular grooves 5a and 6a are displaced radially inward, that is, contracted. I. The first and second processing stages 12 and 13 are inserted into the outer peripheral surface of the main body portion of the through-holes of the holding frames 5 and 6, and the frame 5 is held by the reduced diameter of the thin portion of the annular grooves 5a and 6a. And 6 is held integrally so as to be rotatable with respect to the frame 65. The rotary indexing table 60 detects the rotation angle from the reference position of the i-th and second processing stages 丨2, 丨3, and includes The indexing angle detecting sensor 16 of the rotating side sensor portion i 6a and the fixed side sensor portion 16b is rotated side sensor portion 16 & The screw 27 is fixed to the second processing table i3 side end portion of the second holding portion 8c of the rotor 8, and the fixed side sensor portion i 6b is fixed to the second side frame 4 by the screw 26, and the two sensor portions are fixed. The circumferential surfaces of the crucibles 6a and 16b are opposed to each other.
