Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a side panel setting device used in an assembly line of an automobile body.

(Prior Art) Conventionally, according to JP-A-59-114173, a reciprocating set trolley is provided between a set station and a coupling station in front of the set station, and a floor, a side panel, which are vehicle body constituent members, in the set station, The roof is set in a predetermined positional relationship on the set trolley, these members are conveyed to the joining station in the set state by the set trolley, and these members are welded and joined by the welding jigs arranged on both sides of the joining station. A vehicle body assembly line for assembling a vehicle body is known.

Further, in this one, a side panel setting device, which is provided with a set jig for holding the side panel on the elevating frame so as to be capable of advancing and retreating in the lateral direction, is arranged on both sides of the set station, and is placed above the set station by a hanger. The left and right side panels that are carried in are received by the setting jig of each of the setting devices so that the side panels are automatically set.

As shown in FIGS. 13 to 15, the setting jig includes a jig body b supported by an elevating frame a so that it can be moved forward and backward by a cylinder b ₁ , and a side panel W ₂ on a roof side rail. V-shaped hook c to be suspended at w _2a is attached to cylinder c ₁
And the center pillar
A clamp member d for holding w _2c from the front and rear is provided on a movable frame d ₂ which is movable inward and downward in a lateral direction by a cylinder d ₁ so that it can be opened and closed by a cylinder d ₃ , and a jig body b of mounting the rocking frame e ₂ which is swung by the cylinder e ₁ to the bracket b ₂ which is vertically at a rear end portion, rocking Dowaku e ₂ engagers e a cylinder e ₃ to be engaged with the rear fender w _2d in The set jig is lifted to the same level as the hanger by the elevating frame to move the jig body b inward in the lateral direction, and then the hook c is first swung upward. The roof side rail w _2a of the side panel W ₂ suspended on the hanger is scooped up, and then the movable frame d ₂ is moved inward in the lateral direction to close the clamp member d and thereby the center pillar w
_The side panel W ₂ is positioned in the front-rear direction by sandwiching _2c , and then the swinging frame e ₂ swings the engaging element e into the rear fender w _2d so as to engage with the rear fender w _2d and the engaging element e is moved to the cylinder e. ₃
Thus, the side panel W ₂ is laterally positioned by pulling it laterally outward and changing the attitude of the side panel W ₂ from the hanging attitude to a predetermined set attitude with a slight inward tilt.

(Problems to be Solved by the Invention) In the above-mentioned one, since the side panel W ₂ is changed in posture from the suspension posture to the set posture by the engagement element e, the engagement element e is changed.
Requires a large movement, the moving mechanism of the engaging element becomes large and complicated, and the moving mechanism for the clamp member d composed of the movable frame d ₂ described above is also required to cope with the posture change of the side panel. However, there is a problem that the structure becomes complicated and expensive.

Further, those mentioned above, but the roof side rail w _2a side panel W ₂ is such that suspended in the V-shaped hook c, roof side rails on the hook c caused by a change in the posture of the side panel W ₂ as may allow tilting of w _2a, it is necessary to form to those with some play in the transverse direction a hook c to the roof side rail w _2a, side panels and a result the roof side rail w _2a is lateral There is a problem that the positioning accuracy of W ₂ deteriorates.

The present invention provides a device capable of simplifying the structure of the setting jig and reducing the cost by fixing the means for positioning the side panel in the front-rear direction and the lateral direction to the setting jig. The first purpose is to do so, and the second purpose is to accurately position the roof side rail in the lateral direction and improve the positioning accuracy of the side panel.

(Means for Solving the Problem) In order to achieve the first object, the invention of claim 1 is a setting device for receiving a side panel of an automobile body from a hanger and setting the side panel in a fixed position, which is a lifting frame. A set jig having a member for positioning the side panel in the front-rear direction and the lateral direction and a suspending member for suspending the side panel on the roof side rail above the transverse direction toward the side panel suspended on the hanger. A slide frame that can move forward and backward in the lateral direction is attached to the elevating frame, and the set jig is supported by the slide frame so as to be tiltable in the lateral direction about the longitudinal axis. .

Further, in the invention of claim 2, in order to achieve the second object, the suspension member is provided with a laterally long guide piece for slidably supporting the flange portion of the lower edge of the roof side rail. A clamp member having a clamp seat for receiving a side surface of a flange portion provided on the proximal end side of the guide piece and a clamp piece for clamping the flange portion between the clamp seat and capable of opening and closing in the longitudinal direction of the guide piece. did.

Further, it is desirable to provide a means for moving the setting jig in the front-rear direction as in the invention of claim 3 so as to cope with the displacement of the setting position of the side panel in the front-rear direction due to the model change.

(Operation) The operation of the present invention will be described based on the invention of claim 2.

Raise the set jig to a position facing the side of the side panel that is hung on the hanger by the elevating frame, and then move the set jig laterally inward toward the side panel by the slide frame to hang it. After inserting the guide piece of the member into the space below the roof side rail of the side panel, the set jig is tilted so as to follow the side panel in the suspended posture. According to this, the guide piece tilts forward and upward toward the front end side, the roof side rail is scooped up from the hanger by the guide piece, and the side panel is suspended from the guide piece in a hanging posture along the setting jig. Even if the setting jig is suspended and the positioning means in the front-rear direction and the lateral positioning member are not provided by the moving mechanism so as to be able to advance and retreat in the lateral direction, the predetermined positioning positions of the side panel are exposed to these positioning members, Thus, even if these positioning members are fixedly provided on the setting jig, the side panels can be positioned in the front-rear direction and the lateral direction by these positioning members when the setting jig is tilted. Further, by closing the clamp piece of the suspension member, the flange portion at the lower edge of the roof side rail is clamped between the guide piece and the clamp seat, and the roof side rail is laterally positioned. .

After the side panel is positioned and held on the set jig as described above, the set jig is tilted in the opposite direction to change the posture of the side panel from the suspended posture to the predetermined set posture. Lower to perform the side panel setting work.
