It is provided.

As shown in Figs. 2 and 3, the receiver rotation switching type locators 5a, 5b
Are provided one above the other so as to press the upper and lower portions of the outer surface of the door, and they have substantially the same configuration except for the shape of the receiver. The upper locator 5a is
FIG. 4 is provided with four receivers 51a (only one of which is shown in the drawings) having a contact holding surface corresponding to the shape of the upper portion of the outer surface of the door. As shown in FIG. 4, the four receiving members 51a are attached to the rotary shaft 52a at angular positions that maintain an angular interval of 90 ° from each other.

As shown in FIG. 5, a swing vane type pneumatic motor 53a (a shaft driving motor) is arranged at one end of the rotary shaft 52a, and the rotary shaft of the pneumatic motor 53a rotates via a shaft joint. It is keyed to one end of the shaft 52a.

At the outer end of the rotary shaft of the pneumatic motor 53a, as shown in FIG. 6, a two-pronged stopper plate 54 having an opening angle of 90 ° is formed.
a is fixed, and both outer side surfaces S ₁ and S _{2 of the} stopper plate 54a serve as stopper working surfaces.

A swing vane type pneumatic motor 56a is further arranged at one end of the rotary shaft 52a, and a spur gear 57a is keyed to the rotary shaft of the pneumatic motor 56a. By the way, the above-mentioned stopper plate 54a has a cylindrical portion along the pneumatic rotation axis as shown in FIG. 5, and the sector gear 58a is loosely fitted to this cylindrical portion via a bush. The sector of the sector gear 58a has an opening angle of about 180 °, and a hydro cushion 59a is attached to the outer surface of the sector gear 58a. The hydro cushion 59a functions as a stopper in cooperation with the outer side surfaces S ₁ and S ₂ of the stopper plate 54a described above, and the stopper action surfaces C ₁ and C ₂ are exposed with the rod of the hydraulic damper. Is a stop surface with cushioning action, and constitutes a rotation stopper rotated by a pneumatic motor 56a as a rotation stopper driving motor. A fixed stopper 60a attached to the bracket is provided in the rotation surface of the sector gear 58a, and the rotation range of the hydro cushion 59a as the rotation stopper is defined in cooperation with the end surface of the hydro cushion as these stoppers. Play a role.

On the other hand, the lower locator 5b is configured as shown in FIG. 7 and has substantially the same configuration although the dimensions and the like are different. Therefore, the parts corresponding to the respective parts in the upper locator 5b have the same reference numerals. The description will be replaced only by showing b in reference.

In the receiver rotation switching type locator configured in this manner, the rotary shaft 52a is rotated by the drive of the pneumatic motor 53a to switch the contact holding surface of the receiver. The operation in this case will be described.

First, as shown in FIG. 8 (A), in the original position, the rotary shaft 52
The a key is located at the lower right 45 °, the ports P ₁ P ₄ of both motors 53a and 56a are set to the pressurizing side, and the surface S of the stopper plate 54a is
₁ is pressed against the surface C ₁ of the hydro cushion 59a, the end surface of the lower sector gear 58a is pressed against the stopper 60a (see FIG. 6). At this time, 4 attached to the rotary shaft 52a
One of the receivers will be in its operative position.

Such are switched P ₂ port of pneumatic motor 53a is in the pressure side in the state, by rotating the shaft of the motor 53a in the clockwise direction, the stopper plate 54a is the surface S ₁ from the surface C ₁ of the hydro cushion 59a Surface S ₂ is hydrocushion 5 away
Rotate until it reaches the cushion surface C ₂ on the opposite side of 9a. The rotation angle at this time is 180 °, and at the end position of this rotation,
The second receiver is placed in its operative position. This is the 8th
It is shown in FIG.

Next, when the port P ₃ of the pneumatic motor 56a is set to the pressurizing side and air is fed under pressure, the spur gear 57a rotates counterclockwise, and the sector gear 58a rotates clockwise with this rotation. Therefore, the hydro cushion 59a attached to the gear 58a rotates clockwise. The rotation angle of the sector gear 58a and the hydro cushion 59a is the spur gear.
90 ° for rotation angle 270 ° of 57a and pneumatic motor 56a
It has been decelerated to 1/3 so that.

When the hydro cushion 59a has stopped at this position, air is pumped to the port P ₁ side of the pneumatic motor 53a this time, and the stopper plate 54a rotates as the vane rotates.
Is turned clockwise and its surface S ₁ is
It comes back to a position where it abuts the surface C ₁ of a and stops. In this position the third receiver is in its operative position. This state is shown in FIG. 8 (c).

Further, when the pressure feeding of air to the pneumatic motor 53a is reversed and the vane is rotated in the counterclockwise direction, the stopper plate 54a in turn rotates the surface S ₂ of the surface of the hydrocushion 59a.
Rotate counterclockwise until it touches surface C ₂ of. At the position where this rotation has ended, the fourth receiver is placed in its operating position. This final state is shown in FIG.

In this way, the stopper plate 54a can take four positions with different angles by 90 ° in combination with the change of the stop position of the hydro cushion 59a, and at each of these positions, the air pressure to the vane of the motor can be reduced. Keep a stable stop state due to load.

Therefore, according to this locator, it is possible to take four stable shaft rotation stop positions by the stoppers that only regulate the both ends, and without providing an unstable intermediate stop position or a detent mechanism therefor, The effect that the receiver can be placed in a stable position where the circumference is equally divided is obtained.

As described above, according to the jig device provided with this receiver rotation switching type locator, it is possible to correspond to four types of doors having different outer shapes according to the vehicle type by cooperating with other locators. It is possible to unify the jig device for holding the jig device, and it is possible to obtain an effect of significantly reducing the installation space of the jig device.

[Effect of device]

As described in detail above, according to the receiver rotation changeover type jig device of the present invention, by unifying the jig device for holding the assembled parts, the installation space can be greatly reduced and a large size When applied to parts, it is possible to achieve the effect of reducing the number of processes, and further, it is possible to obtain the effect of ensuring a well-balanced support position because the part receiving position is constant. become.
