It can follow the shape of the contact surface 43a of each adjusting member 41a.

On the other hand, when the position of each receiving surface 25a is changed in order to perform the work of assembling various parts to the base material of another type of door trim, the first electric cylinder 51 is operated as shown in FIG. By causing each adjusting member group 40 to be displaced downward, each adjusting member group 40 is separated from each receiving member group 20. In this state, each receiving member 21 descends due to its own weight, and the lower surface of the receiving portion 25 comes into contact with the spacer 33. Further, in this state, the second electric cylinder 61 is operated so that one of the adjusting members 41a to 41c, for example, the adjusting member 41b is placed at a position facing the lower end 24 of each shaft portion 22 in the vertical direction Y.

As a result, the lower end 24 of the shaft portion 22 of each receiving member 21 is brought into contact with the contact surface 43b of the adjusting member 41b after switching, so that the position of each receiving surface 25a in the vertical direction Y is set to the adjusting member 41b. It is possible to follow the shape of the contact surface 43b of.

Next, the effect of this embodiment will be described.
(1) The jig 10 includes a receiving member group 20, a supporting member 31, and an adjusting member group 40. The receiving member group 20 includes a plurality of receiving members 21 provided on the shaft portion 22 and the upper end 23 of the shaft portion 22 and having the receiving portion 25 having the receiving surface 25a, and the respective shaft portions 22 are parallel to each other at intervals. And are arranged. The support member 31 supports each shaft portion 22 in a displaceable manner along the vertical direction Y of the shaft portion 22. The adjusting member group 40 has contact surfaces 43a, 43b, 43c, and the lower end 24 is brought into contact with the contact surfaces 43a, 43b, 43c to adjust the position of each receiving surface 25a in the vertical direction Y. A plurality of adjusting members 41a, 41b, 41c in which the shapes of the contact surfaces 43a, 43b, 43c change in the parallel direction X of each shaft portion 22 are different from each other are included.

Further, the jig 10 has a displacement mechanism 50 that displaces the adjusting member group 40 in the vertical direction Y, and among the adjusting members 41a, 41b, 41c in a state where each receiving member group 20 is separated from the adjusting member group 40. It is provided with a switching mechanism 60 for switching one of the above positions in the vertical direction Y to a position facing the lower end 24 of each shaft portion 22.

According to such a configuration, since the above-mentioned action is obtained, it is possible to receive a plurality of types of door trims having different shapes.
(2) A fixing member 44 for fixing the adjusting members 41a, 41b, 41c constituting the adjusting member group 40 in a parallel state in the orthogonal direction Z is provided, and the switching mechanism 60 fixes the fixing member 44 in the orthogonal direction Z. By displacing along the line, one of the adjusting members 41a, 41b, 41c is switched to the facing position.

According to such a configuration, the adjusting members 41a, 41b, and 41c can be easily switched by displacing the fixing member 44 along the orthogonal direction Z. Further, since the adjusting member group 40 may be fixed to the fixing member 44 in a parallel state along the orthogonal direction Z, the adjusting member 41a, by rotating the fixing member 44 around an axis extending along the orthogonal direction Z, The physique of the entire jig 10 can be made smaller than the configuration in which 41b and 41c are switched.

According to such a configuration, the receiving members 21 are arranged at intervals in both the parallel direction X and the orthogonal direction Z. Thereby, the position of each receiving surface 25a in the vertical direction Y can be set in both the parallel direction X and the orthogonal direction Z. Therefore, the door trim can be received stably.

(4) Each receiving surface 25a has a rectangular shape, the long side direction of the receiving surface 25a coincides with the orthogonal direction Z, and the short side direction of the receiving surface 25a coincides with the parallel direction X.
In the above configuration, the adjusting members 41a, 41b, 41c constituting the adjusting member group 40 are fixed to the fixing member 44 in a parallel state in the orthogonal direction Z. Therefore, it becomes a constraint in reducing the distance between the receiving members 21 adjacent to each other in the orthogonal direction Z.

On the other hand, the distance between the receiving members 21 adjacent to each other in the parallel direction X can be made smaller than the distance between the receiving members 21 adjacent to each other in the orthogonal direction Z.
In this respect, according to the above configuration, the shape of each receiving surface 25a is rectangular, and the long side direction and the short side direction of the receiving surface 25a coincide with the orthogonal direction Z and the parallel direction X, respectively. Therefore, it is possible to reduce the distance between the receiving members 21 adjacent to each other in both the orthogonal direction Z and the parallel direction X and to increase the area of the receiving surface 25a. Therefore, the door trim can be received stably.

<Change example>
The above embodiment can be modified and implemented as follows, for example. The present embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.

-Other actuators such as a hydraulic cylinder may be adopted in place of the first electric cylinder 51 and the second electric cylinder 61.
If the movable plate 35 can be displaced along the vertical direction Y by the first electric cylinder 51, the guide pillar 52 may be omitted.

If the fixing member 44 can be displaced along the orthogonal direction Z by the second electric cylinder 61, the rail 36 and the slide member 45 may be omitted.
Even if the first electric cylinder 51 is operated to displace each adjusting member group 40 downward in order to separate each adjusting member group 40 from each receiving member group 20, the shaft portion 22 of the receiving member 21 is a support member. By being caught on the inner surface of the hole 32 of 31, there is a possibility that the receiving member 21 will not descend until it comes into contact with the spacer 33.

As shown in FIG. 7, a flange 22a is provided between the lower end 24 of the shaft portion 22 and the support member 31, and an urging member such as a compression spring 39 is provided between the support member 31 and the flange 22a to receive the receiver. The member 21 can also be urged toward the contact surfaces 43a, 43b, 43c.

According to the above configuration, it is possible to suppress the formation of a gap between the contact surfaces 43a, 43b, 43c of the adjusting members 41a, 41b, 41c and the lower end 24 of the shaft portion 22. As a result, the receiving member 21 can be lowered until it comes into contact with the spacer 33. Therefore, the position of the receiving surface 25a in the vertical direction Y can be aligned with the shape of the contact surfaces 43a, 43b, 43c of the adjusting members 41a, 41b, 41c.

The long side direction of the receiving surface 25a may be made to coincide with the parallel direction X, and the short side direction may be made to coincide with the orthogonal direction Z.
The receiving portion 25 is not limited to a rectangular plate shape, but may have another shape such as a hemispherical shape.

-In the above embodiment, the switching mechanism 60 for switching one of the adjusting members 41a, 41b, 41c to the facing position is illustrated by displacing the fixing member 44 along the orthogonal direction Z. The switching mechanism 60 may be configured to switch one of the adjusting members 41a, 41b, 41c to the facing position by rotating the fixing member. In this case, for example, the fixing member 44 is a regular polygonal prism such as a regular tetrahedron extending along the parallel direction X, and the adjusting member group 40 is provided on each side surface of the regular polygonal prism. Then, the fixing member 44 may be rotated around a rotation axis passing through the center of the pair of bottom surfaces of the regular polygonal prism.

-The article received by the jig according to the present invention is not limited to the door trim, and can be applied to any article.
