DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of attaching a vehicle body end panel, such as a front end panel or a rear end panel, which is installed laterally at the front or rear end of a vehicle body.

BACKGROUND ART Conventionally, for example, at the front end of a vehicle body, a hood ledge panel that crosses the side wall of the engine room at the front of the vehicle body is fixed to a vehicle body frame member in advance in a facing manner.

After that, the front end panel is positioned between the front ends of the 7-drayage panel using a jig and spot welded. reference).

Problem to be Solved by the Invention Today, when positioning the front end panel between the front ends of the hood hedge panels, it is difficult to position the front end panel between the front ends of the hood hedge panels.
Therefore, if you try to improve the assembly consistency of the front end panel, you will have to use a high-precision robot or perform grueling teaching, which will be disadvantageous in terms of cost. The robot arm that positions the end panel must continue positioning until the spot welding has progressed to a certain extent and the front end panel is fixed to the hood ledge panel, which delays the start of the primary movement and reduces operating efficiency. It also had the disadvantage of

The present invention was made in view of these conventional problems, and it makes it possible to assemble end panels in the correct position without using a high-precision robot, and also makes it possible to assemble the end panel in the correct position without using a high-precision robot. The present invention provides a method for attaching a vehicle body end panel that enables the next movement to be started quickly.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a panel member that is disposed opposite to each other on both sides of the end of the vehicle body and extends in the longitudinal direction f of the vehicle body. a horizontal first guide surface;
forming a second guide surface that rests on the outer side of the guide surface;
An engagement hole is formed in the first guide surface, and mounting pieces are formed on both sides of the upper end of the end panel constructed between the end faces of the panel members, and the mounting pieces are attached to the first guide surface. The end panel is brought into sliding contact with the second guide surface and guided into the engagement hole and locked, and after the end panel is suspended between the end faces of the panel member via the attachment piece, it is fixed.

Effect: In the above configuration, the mounting piece can be attached to the first one without controlling the end panel with high precision. By slidingly contacting the second guide surface, the position is regulated in the height direction and the vehicle width direction, and the panel material is positioned accurately on the end surface of the panel material. Furthermore, by locking the attachment pieces in the engagement holes, the end panel is temporarily attached in a suspended state between the end faces of the panel members.

EXAMPLE An example of the present invention will be described below with reference to FIG. TfnK. That is, as shown in FIG. 1.2, front side members 2.2 extending in the longitudinal direction of the vehicle body are disposed on both sides of the front part of the body l. A hood ledge panel 3.3, which is a panel member that similarly extends in the longitudinal direction of the vehicle body, is attached to the outer surface of the vehicle body 2 so as to face each other. A front edge flange 4 is formed on the front edge of the hood ledge panel 3, and a horizontal fnl guide surface 5 and an outer fi of the first guide surface 5 are formed on the upper edge.
& the second guide surface 6 which is raised up is bent and formed.

Near the front edge of the first guide surface 5, there is a bolt insertion hole 7 having a weld nut (not shown) on the lower surface side. An engagement hole 8 is formed near the bolt insertion hole 7 on the rear side of the vehicle body.

Further, a first cross member 9 is installed horizontally at the lower part of the front end of the hood ledge panel 3, and a cowl box 10 is installed horizontally at the upper part of the rear end.
The upper edge of the dash panel 12, which separates the engine compartment 11 from the hood ledge panel 3.3, is joined to the hood ledge panel 3.3. Inside the engine room 11, there is a power train 13 including an engine. Radiator 14. Various functional parts such as a battery 15 are assembled.

On the other hand, the front end panel 16 installed horizontally between the front end surfaces of the hood storage panel 3 has an upper rail 17 at the top,
A radiator core support panel 18 is joined to the lower surface of the upper rail 17. At both ends of the upper rail 1f.

A mounting piece 19 is attached, and a claw 2o is also formed at the lower end of the mounting piece 19.

Further, the mounting piece 20 has a bolt insertion hole 21.21 formed therein, and a side edge flange 22 extending in a direction perpendicular to the upper rail 17 is formed on the outer edge thereof.

In the structure of each part, the front end panel 16
1, for example, from the front side of the hood ledge panel 3 as shown by the arrow in FIG. 2, the side line 7 lunge 22. is the second
The claw 20 slides in contact with the guide surface 6 to regulate its position in the vehicle width direction (X direction), and the lower end of the pawl 20 slides in contact with the first guide surface 5 to regulate its position in the height direction (Y direction). In this way, the side edge flange 22 and the claw 20 are
゜If the radiator core support panel 1B is moved in the direction of the arrow while slidingly contacting the second guide surfaces 5 and 6, the radiator core support panel 1B will eventually come into contact with the leading edge flange 4 of the hood ledge panel 3 and move in the longitudinal direction (two directions) of the vehicle body. Positioning is done. Therefore, when a robot hand is used for the work of attaching the front end panel 16, there is no need to teach the herders so that the front end panel 16 is moved to the appropriate position on the front edge of the hood ridge panel 3. The front end panel 16 can be guided to an appropriate position by simple feedback control using a limit switch that detects sliding contact with the two guide surfaces 5°6 and contact with the leading edge flange 4.

Furthermore, along with the training of the front end panel 16, the claw 20
When the front end panel 16 is guided into the engagement hole 8 and locked, the front end panel 16 is suspended between the front ends of the hood ridge panels 3 and 30 via the attachment pieces.

Therefore, the robot that has positioned the front end panel 16 is released from the positioning work 17 at this point.
First-order behavior can be started, and the robot can be operated efficiently. The first guide surface 5 and the mounting piece 1 are brought into contact with each other by the claw 20 being engaged with the engagement hole 8.
The installation work of the front end panel 16 is completed by inserting and screwing the bolts 23 into the bolt insertion holes 7.21 of 9 and connecting the peripheral edge of the radiator core support panel 18 to the peripheral edge 7 of the dredge panel 30.
