グ・アンローデイング装置を示す。 Further, a fixed plate 41 is fixed to the front surface of the swinging member 33, and the drive engagement member 39 is attached to the fixed plate 41 in the circumferential direction of the workpiece W.
An engaging portion 42 is formed at a position different in angular position from the above, and a pressing portion 43 is formed at a position facing the engaging portion 42 across the spindle axis. This one engaging portion 42 comes into contact with the side of the workpiece W as the swinging member 33 rotates counterclockwise, and applies a reaction force F2 to the workpiece W. This reaction force F2
is substantially canceled out by the driving force F1 applied by the drive engagement member 39 to the workpiece W, so that no radial bending moment is applied to the workpiece W. The other pressing portion 43 is elastically deformable by the slit 44, and uses this elastic force to press the workpiece W toward the engaging portion 42,
Even if the direction of action of the grinding resistance changes, the workpiece W does not separate from the engaging portion 42. Furthermore, 45
47 is a spacer that regulates the amount of elastic deformation of the pressing portion 43 to prevent breakage of the elastic deformation portion 46; 47 is a face plate 30;
A support ring 48 is fitted onto the drive pin 32 and is made of a wear-resistant material, allowing the swing member 33 to swing smoothly. In addition, 80 in FIG. 1 is a temporary holder for the workpiece W fixed on the rocking table 13;
1 is a workpiece W fixed to the ram 23 of the tailstock 22
The temporary cradle 82 is a protrusion facing the end surface of the workpiece W on the temporary cradle 81, and is provided in order to pull out the left end of the workpiece W to the left of the drive device when the ram 23 retreats. Further, 85 indicates a well-known automatic loading/unloading device as described in, for example, Japanese Utility Model Publication No. 44-17595.

Indicates a stopped state.

向に引出すことができる。 Next, the ram of the tailstock 22 is retracted by a cylinder device (not shown), the tailstock center 24 is removed from the center hole of the workpiece W, and the projection 82 is moved from the workpiece by the subsequent retraction of the ram 23. Move the workpiece W to the right by pushing the end face of the W, and move the workpiece W from the spindle center 21.
Remove the center hole of the workpiece W and pull it out until the left end of the workpiece W is positioned to the right of the drive device in FIG.
In this state, the workpiece W is supported by the temporary supports 80 and 81. Due to this axial movement of the workpiece W, the drive engagement member 39 retreats in a direction away from the engagement recess S by the action of the tip engagement surface 40 against the repulsive force of the elastic member 50, and the workpiece Since it rides on the outer peripheral surface, the workpiece W can be pulled out smoothly in the axial direction.

The unprocessed workpiece W is carried between both centers 21 and 24 with the angular phase of the engagement recess S matched with that of the drive engagement member 39 in advance, and is placed on the temporary cradle 80 and 81.
After being placed on top, it is released from the gripping claws.

At the same time, the workpiece W is fitted onto the temporary holders 80, 81.
It rises from above and is supported by both centers 21 and 24. Due to this axial movement of the workpiece W, the workpiece shaft end comes into contact with the tip engagement surface 40, and the key 39a of the drive engagement member 39 is moved against the outer peripheral surface of the workpiece by the action of the tip engagement surface 40. It rides on the top, and then engages with the engagement recess S by the force of the elastic pressure member 40.

回転駆動される。 When the engagement of the drive engagement member 39 with the engagement recess S is detected by a proximity switch (not shown), the piston rod 78 is disengaged from the index plate 75, and then the main shaft 15 is moved counterclockwise in FIG. When rotated in the direction, this rotation is transmitted to the swinging member 33 via the drive pin 32 on the face plate 30.
This counterclockwise rotation of the swinging member 33 causes the engaging portion 42 to come into contact with the side surface of the workpiece, thereby applying a reaction force F2 to the workpiece W. This reaction force F2 is balanced with the driving force F1 of the drive engagement member 39, and the workpiece W is rotationally driven without applying a moment in the radial direction.

However, by rotationally driving the main shaft 15, only the drive engagement member 35 rotates with respect to the stationary workpiece W, and when the phases of the two match, the engagement recess S is moved by the repulsive force of the spring 38. There is no problem as it engages with the

一番号を付して示す。 The present invention is not only applicable to the workpiece W having the half-moon-shaped engagement recess S on the front side as described above, but also has a pin on the rear end surface as shown in FIGS. 5 and 6. It is also applicable to a workpiece W having a hole-shaped engagement recess S. In this embodiment, in relation to the difference in the engagement recesses S, the pin-shaped drive engagement member 39 can be moved forward and backward toward the engagement recesses S in a direction parallel to the spindle axis and in a direction intersecting the rotational direction of the workpiece W. The point that the swinging member 33 is fitted and supported by the fitting hole 51 on the swinging member 33 is
This embodiment differs from the previous embodiment in that it is swingably supported by a drive pin 32 located on the same side as the drive pin 32, that a cross-shaped swinging member 33 is used, and that the guide member 35 is constructed as a single piece. , and other basic configurations are substantially the same as those of the embodiment described above, so explanations thereof will be omitted, and those having the same functions as those of the embodiment described above will be designated by the same reference numerals.

The drive engagement member 39 rotates relative to the workpiece W, and when the rotational phases of the drive engagement member 39 and the workpiece W match, the drive engagement member 39 engages with the engagement recess S by the repulsive force of the elastic pressure member 50.

Therefore, the workpiece W can be rotationally driven without applying a moment in the semi-longitudinal direction.

なる利点がある。 As described above, the drive device of the present invention moves the drive engagement member forward and backward by engaging the end of the workpiece shaft with the front end engagement surface of the drive engagement member. The driving engagement member can be engaged with an engagement recess such as a keyway or a pin hole without any trouble, and there is an advantage that automatic loading is possible.

進退させることができる利点がある。 Further, in the drive device of the present invention, the swinging member is swingably supported with respect to the main shaft by the drive pin, and the drive engagement member is movably supported on the swinging member. The abutting operation of the abutting part and the engaging operation of the drive engaging member can accurately and reliably abut or engage at a predetermined location with respect to the workpiece without affecting each other. Since the rocking member only moves in one direction, a drive pin pivot structure can be used, which simplifies the support configuration and allows the rocking member to move in two directions.
There is no need for a complicated connection mechanism that allows for dimensional floating, and the simple structure means that the swinging member and drive engaging member can swing smoothly over a long period of time without being affected by chips, etc. It has the advantage of being able to advance and retreat.
