After the measurement, etc. are completed, the motor 33 is driven in the opposite direction, and the transmission member 36, driven pulley 37, and shaft 38 are rotated via the reduction gear to drive the drive pulley 35, and the stop lever 39 is moved to the stop position. 41D, the base 2 and the thin plate spring component 1 are returned to their original positions.

The holding device for the thin plate spring component 1 of the above embodiment operates as follows.

That is, a thin plate spring component l as a workpiece is placed on the suction table 3.
When the thin plate spring component 1 is installed, the thin plate spring component 1 is suctioned by the vacuum suction hole 4 provided in the suction table 3.

When the thin plate spring component 1 is attracted to the suction table 3, the lever 7 of the drive section of the slide block 6 is moved by an external force to the fourth position.
The system slide block 6 is rotated in the direction of the arrow a in the figure, and the tension spring 9 moves the system slide block 6 toward the forward side shown by the arrow in FIG.

When the slide block 6 moves to the forward side, it follows this and the mushy gray) 12.13 moves to the arrow C in Fig. 3.
shoulder portion 1a of the thin leaf spring component 1 on the suction table 3
, lb, and push the thin leaf spring component 1 until it comes into contact with the positioning reference surface 5, thereby determining the position of the thin leaf spring component 1 in the length direction.

Furthermore, when the slide block 6 moves to the forward side,
Cam 1 constituting the operating part of the positioning claws 14 and 15
9.20 follows the slide block 6 and moves in the direction of arrow d in FIG. Along with this, the tension spring 18 causes the positioning claws 14 and 15 to rotate in the direction of closing each other as shown by the arrow e in FIG. Holes P are made on both sides, and the width direction of the thin plate spring component 1 is positioned on the positioning reference line 0-0 shown in FIG.

After completing the positioning of the thin plate spring component 1 in the length direction and the width direction, the driving pulley 29 and the winding part, which constitute the operating section of the clamp breaker 26, are rotated through the transmission member 30 and the driven pulley 31. Clambreper 26
is rotated in the direction of arrow f in FIG. 4, and holds the thin plate spring component 1 between it and the suction table 3.

After the clamp breaker 26 holds the thin plate spring part 1, the motor 33 constituting the feeding means 32 that sends the thin plate spring part 1 together with the base 2 to the next process is driven in the head direction, and the speed reducer 34 and the drive f - The transmission member 36, the driven pulley 37, and the shaft 38 are rotated, and the base 2 is rotated in the direction of arrow g in FIG. Part 1 is sent to the next process such as spring pressure measurement.

After the spring pressure measurement etc. are completed, the motor 33 of the feeding means 32 is driven to rotate in the opposite direction, and the reduction gear 34, the drive pulley 35, and the transmission member 36, the driven pulley 37, and the shaft 38 are rotated. Then, the base 2 is rotated in the direction opposite to the direction of arrow g in FIG.

During this rotation, the stop lever 39 provided on the shaft 38 comes into contact with the stone/4' 41, and the base 2 and thin plate spring component 1 are returned to the position before being sent to the next process.

When removing the thin plate spring component 1, operate the lever 7 constituting the drive section of the slide block 6 in the direction opposite to the direction of the arrow a in FIG. and the member 11 fixed to the slide block 6, the slide block 6 is pushed in the direction opposite to the direction indicated by the arrow in FIG. 12, 13 are separated from the thin leaf spring component 1. In addition, positioning claws 14.15
The cam that makes up the operating section of! 9.20 moves together with the slide block 6, and the positioning pawl 14.15 is rotated by the cam follower 21.22 in the opposite direction of the arrow 60 in FIG. 3 to open. Further, the drive pulley 29, which constitutes the operation section of the clamp lever 26, is driven in the direction of the crane, and the clamp lever 26 is rotated by the arrow shown in FIG. Rotate in the opposite direction of f. Then, the vacuum suction is released and the thin plate spring component 1 is taken out.

As mentioned above, in this embodiment, when the slide block 6 moves toward the forward side, the Zoscher grates 12 and 13 follow the slide block 6 and push the thin plate spring component 1 until it comes into contact with the positioning reference surface 5, and the thin plate spring component 1 The lengthwise position of the component 1 is determined, and the positioning claw 1 is
4. 15 is operated in the closing direction, and the positioning claws 14 and 15 hold both sides of the thin plate spring component 1 in the width direction, so that the widthwise position of the thin plate spring component 1 is determined on the positioning reference line 0 to 0. Therefore, thin plate spring part 1
can be positioned with high precision.

In addition, in this embodiment, after positioning the thin leaf spring component 1, the thin leaf spring component 1 is held between the suction table 3 and the clamp lever 26, so that the thin leaf spring component 1 is ensured in the position as it was positioned. can be held.

Further, in this embodiment, after the thin plate spring component 1 is positioned and held, the thin plate spring component 1 is
is sent to the next process together with base 2, so
Everything from positioning the thin plate spring component l to holding it and feeding it to the next process can be performed automatically.

Note that the present invention can also be applied to a type of equipment K in which a spring pressure measuring device or the like is moved relative to the thin plate spring component 1 positioned and held on the base 2. It is assumed that the feeding means 32 is omitted.

Further, the structure of each part of the present invention is not limited to the embodiment shown in the drawings, but may be any structure as long as it has the intended function.
