The first hand chuck 84 includes a pair of first chuck members 88. For example, an unprocessed workpiece P is sandwiched and held between the first chuck members 88, and the second hand chuck 86 includes a pair of second chuck members 88. A chuck member 90 is provided, and for example, the processed workpiece P is sandwiched and held between the second chuck members 90 (see FIGS. 1 and 4 ). Incidentally, contrary to the above, the processed workpiece P may be held by the first hand chuck 84 and the unprocessed workpiece P may be held by the second hand chuck 86.

  With respect to the structural wall portion 10 of the lathe body 6 and the first and second hand chucks 84 and 86 of the loader device 4, the following configurations are provided. Mainly referring to FIG. 2, the structural wall portion 10 of the lathe main body 6 (specifically, the mounting support surface 22 thereof) is configured so as to extend upward in the vertical direction and incline rearward, and the inclination thereof. The angle α1 ((the inclination angle α1 of the mounting support surface 22 with respect to the horizontal plane) (see FIG. 2) is preferably linearly inclined in the angle range of 45 to 75 degrees, for example.

  By inclining the structural wall portion 10 (mounting support surface 22) in this way, as shown in FIG. 2, the first turret structure body 14 (such as the turret 30) and the second turret structure body 16 (such as the turret 30). ) And are arranged so as to be inclined rearward upward in the vertical direction, and the inclination arrangement angle α2 (see FIG. 2) of the first and second turret structures 14 and 16 to the rear side is It becomes substantially equal to the inclination angle α1 of the wall portion 10 (α1=α2). Inclining the structural wall portion 10 of the lathe body 6 in this manner (in other words, disposing the first turret structure body 14 on the upper side and the rear side of the second turret structure body 16) The height can be reduced to ensure a space above it for the hand support mechanism 66 of the loader device 4, and the loader device 4, particularly the lifting member 74 and the hand unit 78, can be provided above the front side of the lathe body 6. It is possible to secure a moving space for the movement (see FIGS. 1 and 2).

Further, mainly referring to FIG. 4, the first hand chuck 84 (the pair of first chuck members 88) of the hand unit 78 is located above the second hand chuck 86 (the pair of second chuck members 90) in the up-down direction. In addition, it is preferable that the first and second hand chucks 84 and 86 are arranged rearward in the front-rear direction, and the rearward inclination angle α3 is, for example, 15 to 45 degrees.

  By arranging the first and second chuck hands 84 and 86 of the hand unit 78 in an inclined manner in addition to the inclination of the structural wall portion 10 of the lathe body 6 as described above, the following operational effects are achieved. In the conventional lathe machining system, the first and second hand chucks 84 and 86 are arranged at the same height position in the front-rear direction, so that the second hand chuck 86 is moved to the arrow 98 as estimated from FIG. When attempting to hold the workpiece P supported by the swing stop 44 by moving it in the direction shown by, a part of the first hand chuck 84 and a part of the shake stop 44 come into contact with each other. In order to avoid such interference, it is necessary to retract the anti-vibration tool 44 rearward (direction of retracting from the main shaft portion 12). On the other hand, in this lathe machining system, as shown in FIG. 5, the first hand chuck 84 is arranged above the second hand chuck 86, and therefore the second hand chuck 86 is moved to the arrow 98. Even if it is moved in the direction indicated by, the tip of the first chuck member 88 (front chuck member 88) of the first hand chuck 84 moves as indicated by the alternate long and short dash line 100, and the swing stop 44 of the lathe body 6 side moves. The workpiece P can be held without interfering with a part and without retracting the swing stop 44 to the rear side.

  Next, replacement of the workpiece P in the above-described lathe processing system is performed as follows, for example. Mainly referring to FIGS. 1, 2 and 5, in order to replace the workpiece P, for example, the unprocessed workpiece P is held by the first hand chuck 84 of the hand unit 78 (at this time, the second hand). The chuck 86 does not hold the workpiece P), and the lateral movement member 72 is laterally moved via the first movement guide means (not shown) while the workpiece P is held in this manner, and the longitudinal movement member 73 is moved to the second position. It is moved in the front-rear direction via movement guide means (not shown), and the elevating member 74 is further moved downward via third movement guide means (not shown). Then, when holding the workpiece P held by the swing stop member 50 of the swing stop 44 by the second hand chuck 86 of the hand unit 78, the hand unit 78 is indicated by an arrow 98 by downward and backward combined movement. And the second hand chuck 86 of the hand unit 78 holds the processed workpiece P.

  When the processed workpiece P is held by the hand unit 78 (second hand chuck 86) in this manner, the holding by the vibration stop 44 is released, and the holding by the chuck means 18 is released. The processed workpiece P can be removed.

  Thereafter, the hand support mechanism 66 moves the hand unit 78 as required, and the unprocessed workpiece P held by the first hand chuck 84 of the hand unit 78 is inserted and held by the chuck means 18 on the lathe body 6 side. In addition, the first hand chuck 86 of the hand unit 78 is released from the holding of the hand unit 78 after being held by the vibration stop 44 and thus held. After moving from the first hand chuck 84 to the chuck means 18 on the side of the lathe body 6 and removing the processed workpiece P, the unprocessed workpiece P is attached to the chuck means 18.

  In this way, the work P is replaced, and the work P held by the chuck means 18 and the vibration stop 44 on the lathe body 6 side is processed. Further, the elevating member 74 is moved upward, and the hand unit 78 holding the processed workpiece P is moved upward via the elevating member 74, and thereafter, the rearward movement of the longitudinal movement member 73 and the lateral movement member 72 are performed. Due to the lateral movement of the workpiece P, the processed workpiece P held by the hand unit 78 (second hand chuck 86) is transferred to the next processing step.

  Although one embodiment of the lathe machining system according to the present invention has been described above, the present invention is not limited to such an embodiment, and various changes and modifications can be made without departing from the scope of the present invention.

  For example, in the above-described embodiment, the swing stop tool 44 including the three swing stop members 50 is used as the workpiece support mechanism 42, but the tailstock that supports the tip end of the workpiece is used as the workpiece support means 42. You may make it use a stand.
