Therefore, when the slide frame is lowered, the jig body connected to the slide frame via the slide shaft is lowered. When the jig body contacts the inner jig body reference, further lowering is prevented. Further, when the slide frame is lowered, one end of the connecting link is attached to the slide frame, and the other end of the connecting link is connected to the side member reference frame, so that the side member reference frame moves outward according to the guide. . The lateral movement of the side member reference frame is performed until it is blocked by the side member stopper.
When the side member reference frame comes into contact with the side member stopper, the slide frame descends. At this time, the upper stopper is projected from the slide frame together with the upper portion of the slide shaft.
Since one end of the connection link is attached to the slide frame, and the other end of the connection link is connected to the side member reference frame, when the slide frame is raised, the side member reference frame moves inward according to the guide. At the same time, the slide frame rises until it contacts the upper stopper.
When the slide frame comes into contact with the upper stopper, the jig main body attached to the lower portion of the slide shaft also rises as the slide frame rises.

DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the present invention will be described with reference to FIGS. 1, 2, and 3 showing front views.
11 is a motor. The motor 11 is installed in the upper part of the assembly process of the assembly line of the automobile body. 12 is a chain. The two parallel chains 12 are driven up and down by a motor 11. Reference numeral 13 denotes an inner hook jig main body reference. The inner jig body reference | standard 13 is installed in the floor surface of an assembly | attachment process. Also on the outside of the inner jig body reference 13, the inner jig body main reference is installed in a wall shape outside the lowered jig main body 25.
21 is an elevating lower frame. Both ends of the elevating lower frame 21 are attached to the lower end of the chain 12. Reference numeral 22 denotes a slide frame. The slide frame 22 is fixed to the lower surface of the elevating lower frame 21 and is moved up and down together with the elevating lower frame 21 by driving the chain 12 on the inner jig body reference 13.
23 is a slide shaft. The slide shaft 23 is attached so as to be vertically movable through a hole provided in the slide frame 22. Reference numeral 24 denotes an upper stopper. The upper stopper 24 is provided larger in diameter than the hole provided in the slide frame 22, and is attached to the upper portion of the slide shaft 23 to come into contact with the slide frame 22, thereby restricting the lowering of the slide shaft.
[0007]
Reference numeral 25 denotes a jig body. The jig body 25 is attached to the lower part of the slide shaft 23. Reference numeral 26 denotes a guide. The guide 26 is attached to the jig body 25 in the horizontal direction. In this embodiment, the guide 26 is an LM guide. 27 is a side member stopper. The side member stoppers 27 are installed at both ends of the guide 26.
Reference numeral 28 denotes a side member reference frame. The side member reference frame 28 is installed on a guide 26 made of an LM guide and moves according to the guide 26.
29 is a connection link. Both ends of the connecting link 29 are attached to the side member reference frame 28 and the slide frame 22 to connect the two.
31 is a damper stay. The damper stay 31 has one end attached to the guide 26 and the other end attached to the side member reference frame 28, and always biases the side member reference frame 28 outward. When the side member reference frame 28 starts moving, the damper stay 31 is assisted.
[0008]
Therefore, when the motor 11 is driven to extend the chain 12 and lower the slide frame 22, the jig body 25 connected to the slide frame 22 via the slide shaft 23 is lowered. When the jig main body 25 contacts the inner jig main body reference 13, further lowering is prevented.
Further, when the slide frame 22 is lowered, one end of the connection link 29 is attached to the slide frame 22, and the other end of the connection link 29 and the side member reference frame 28 are connected. It moves outward according to the guide 26. The outward movement of the side member reference frame 28 is performed until it is blocked by the side member stopper 27.
When the side member reference frame 28 contacts the side member stopper 27, the motor 11 that receives a signal from a sensor that senses this stops driving and stops the slide frame 22 from descending.
At this time, the upper stopper 24 protrudes from the slide frame 22 together with the upper portion of the slide shaft 23.
[0009]
Therefore, side members of the automobile body are attached to both sides of the side member reference frame 28.
[0010]
After the side members are assembled, the slide frame 22 is raised. Then, since one end of the connection link 29 is attached to the slide frame 22 and the other end of the connection link 29 is connected to the side member reference frame 28, the side member reference frame 28 moves inward according to the guide 26. . At the same time, the slide frame 22 rises until it contacts the upper stopper 24.
When the slide frame 22 comes into contact with the upper stopper 24, the jig main body 25 attached to the lower portion of the slide shaft 23 also rises as the slide frame 22 rises.
