On the other hand, a bracket 30 for supporting the hood lock 6 is integrally provided substantially at the center of the radiator core support 3 in the vehicle width direction along the vehicle body vertical direction (Z direction in the drawing). Hood lock 6
Mounting holes 60, 60 corresponding to the mounting holes 61, 61 and a reference hole 62 corresponding to the mounting hole 63 are formed respectively, and the mounting holes 61, 63 of the hood lock 6 are engaged with the mounting holes 60, 62 of the bracket 30. After they are fitted together, the bolt 90 is inserted and fastened.

Here, the two mounting holes 61 on the hood lock 6 allow relative displacement of the bolt 90 in the vehicle body vertical direction and the vehicle width direction within a predetermined range, while the mounting hole 62 on the radiator core support 3 side is bolted. The relative displacement of 90 in the vertical direction of the vehicle body is allowed within a predetermined range, while the relative displacement in the vehicle width direction is regulated. For example, the mounting hole 61 is ± 0.5 in the vehicle width direction.
mm, the relative displacement of ± 2.0 mm in the vertical direction of the vehicle body is allowed, while the relative displacement allowed by the mounting hole 62 is ± in the vehicle width direction.
The hood lock 6, which is 0.1 mm and ± 2.0 mm in the vertical direction of the vehicle body and is fastened to the radiator core support 3 side by the bolt 90, determines the position in the vehicle width direction by the mounting hole 62 on the radiator core support 3 side. The vertical position of the vehicle body is determined by the position where the engine hood 1 is closed and the striker 7 is locked by the hood lock 6.

The headlamp 5 as a component constituting the front end is fastened to the side panels 31 fixed to the radiator core support 3 on the fender 2 side, and the bolt 5A projecting from the headlamp 5 is mounted on the side.

At the closed position of the engine hood 1 in which the striker 7 is locked by the hood lock 6, the engine hood 1 is moved downward by a predetermined amount by the hood lock 6 against the reaction force F ₁ of the bumper rubber 8. Since only Z ₃ is locked at the position where the bumper rubber 8 is pressed, vibration is prevented from occurring while the vehicle is running. At this time, the hood lock 6
14 locks the engine hood 1 with a predetermined pull-in force F that opposes the reaction force F ₁ of the bumper rubber 8. The engine hood 1 is pulled by the pull-in force F, and the broken line 1'in FIG.
As shown in FIG. 3, the center portion in the vehicle width direction in which the striker 7 is provided is deformed by a predetermined amount Z ₃ downward from the both ends on the fenders 2, 2 side in the vehicle body vertical direction.

In order to lock the engine hood 1 with the hood lock 6 from the open state, a pulling force F which is a force pressing against the buffer member is required.
The retracting force F can be adjusted by changing the retracting amount of the engine hood 1, that is, the amount of deformation of the cushioning member, and changing the mounting position of the hood lock 6 in the vertical direction of the vehicle body. The holes 61, 61 and the reference hole 62 allow relative displacement of the bolt 90 in the vertical direction of the vehicle body within a predetermined range.

Therefore, readjustment is performed after the front end is assembled. There is a problem that the correction process is required, which lowers productivity. Further, in order to keep the pulling force F of the engine hood 1 constant at all times, the mounting position of the hood lock 6 in the up and down direction of the vehicle body should be adjusted. There is a problem that it is necessary to adjust according to the dimensional tolerance, and a correction process is required after the assembly process, which lowers productivity.

Further, as shown in FIG. 14, the central portion of the engine hood 1 locked by the hood lock 6 has a predetermined amount Z.
_Although it is displaced downward by ₃ , this predetermined amount Z ₃ fluctuates depending on the working accuracy of the radiator core support 3 or the like on the vehicle body side, that is, the formation position of the reference hole 62 or the mounting position of the hood lock 6 due to dimensional tolerance. Even when the headlamp 5 is attached to the side panel 31 at a predetermined position through the reference hole 51 shown in FIG. 11, the headlamp 5 inside the vehicle body and the gap Z ₁ between the front end of the engine hood ₁ and the head outside the vehicle body. The gap Z ₂ between the lamp 5 and the front end of the engine hood 1 may be non-uniform and may impair the aesthetics of the vehicle. Therefore, a correction process for adjusting the front end after completion of assembly is required, and production There was a problem of reducing the sex.

Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a front-end assembling apparatus capable of assembling an engine hood or a front-end component with high accuracy and omitting a correction process. To aim.

It is possible to change the mounting position according to.

Assembling of the hood lock 6 by the assembling apparatus 4 configured as above will be described in detail with reference to FIGS.

First, as shown in FIG. 3, the hood lock 6
The mounting hole 61 of the bracket 30 and the mounting hole 60 of the bracket 30 are engaged with each other, and the bolt 90 is inserted into the mounting holes 60 and 61 for temporary fixing, so that the hood lock 6 can lock the striker 7 of the engine hood 1. The hood lock 6 and the vehicle body, that is, the bracket 30
Allow relative displacement of.

Next, as shown in FIG. 4, while operating the lever 47 and the fixed lever 48 to displace the arms 41, 41 to the upper side of the vehicle body, the locate pins 49, 49 projecting from the body 40 of the assembly apparatus 4 are provided. Is inserted into the locate holes 32, 32 of the bracket 30 and the assembling device 4 is locked to the vehicle body. Then, when the lever 47 is opened, the arms 41, 41 urged by the spring 46 are displaced downward toward the body 40. Then, the recess 41A is locked at the position where it abuts on the upper end 6B of the hood lock 6.

In this state, as shown in FIG. 5, the engine hood 1 is closed and the striker 7 is locked by the hood lock 6.

At this time, the hood lock 6 is biased downward by the spring 46 via the arm 41 and is allowed to be displaced in the vehicle width direction by the linear guide 43 of the assembly device 4. , Engine hood 1 striker 7 and radiator core support 3
At the position displaced in the vehicle width direction according to the dimensional tolerance δX in the vehicle width direction, the vehicle is locked at a position in the vehicle body vertical direction that balances the urging force F of the spring 46.

Considering the position of the hood lock 6 in the vertical direction of the vehicle body, as shown in FIG.
A bumper bar 8 as a cushioning member is interposed between the radiator core support 3 and the radiator core support 3, and when the hood lock 6 locks the engine hood 1, the bumper bar 8 is provided.
The reaction force F ₁ above the vehicle body is applied to the hood lock 6 according to the elasticity of
Is added. In order to simplify the explanation, assuming that one bumper bar 8 is evenly arranged on the left and right sides of the hood lock 6 in the drawing, a reaction force 2F ₁ directed upward toward the vehicle body is applied to the hood lock 6.

Now, the temporarily fixed hood lock 6 can be displaced relative to the radiator core support 3, and the hood lock 6 is assembled via the arm 41.
When the urging force of the hood lock 6 is urged downward by the spring 46, and the urging force is the pulling force F similar to that of the conventional example, the hood lock 6 is displaced in the vertical direction of the vehicle body to the position of F = 2F ₁ .

Therefore, the hood lock 6 is set to the engagement position of the striker 7 in the vehicle width direction, while the hood lock 6 is positioned in the vehicle body vertical direction at the retracting force F applied by the spring 46 of the assembly device 4 and the radiator core support 3. The reaction force 2F ₁ of the bumper bar 8 interposed between the engine hood 1 and the engine hood 1 is set at a position where the reaction force 2F ₁ is balanced.

Therefore, the pulling force F of the engine hood 1 is not set according to the mounting position of the hood lock 6 in the vertical direction of the vehicle body as in the conventional example, but the spring 46 is set.
The hood lock 6 can be attached at a position where the pull-in force F given by is balanced.

Thus, after the hood lock 6 is positioned at a predetermined position by the assembling device 4, the bolt 90
After fixing the hood lock 6 to the bracket 30, the engine hood 1 is opened again and the lever 47 is operated to operate the arm 41, as shown in FIG.
41 is displaced upward and away from the upper end 6B of the hood lock 6, and the locate pins 49, 49 are located in the locate holes 32, 3.
2 and remove the assembling device 4 from the vehicle body.

In this way, the hood lock 6 is attached to the arm 41.
It is possible to position the hood lock 6 in the vehicle width direction with reference to the mounting position of the striker 7 by supporting the linear guide 43 so as to be relatively displaceable in the vehicle width direction via the linear guide 43, as shown in FIG. Further, unlike the above-mentioned conventional example, the gaps X _L and X _R between the engine hood 1 and the left and right fenders 2 do not fluctuate, so that the appearance of the vehicle body is maintained and the productivity is improved by eliminating the adjustment process. It is possible.

Then, the hood lock 6 is urged by the spring 6 via the arm 41 toward the lower side of the vehicle body with a predetermined retraction force F, so that the dimensional tolerance in the vertical direction of the vehicle body is absorbed and the retraction force of the engine hood 1 is absorbed. It becomes possible to attach the hood lock 6 to a position where F is always constant, the pulling force F does not fluctuate according to the attachment position of the hood lock 6 as in the conventional example, and the engine hood 1 is kept static. The static closing force Fs, which is the force required to close the vehicle, can be made constant at all times to stabilize the quality, and it is possible to improve productivity by eliminating the adjustment work as in the vehicle width direction. Of.

Here, the static closing force Fs is determined by the engine hood 1.
When the striker 7 is closed, the force that pushes downward against the elasticity of the bumper bar 8 when gradually displacing the striker 7 from the position engaged with the hood lock 6 to the predetermined locking position is shown. According to an experiment by the applicant of the present application, the relationship between the static closing force Fs and the pull-in force F is as shown in FIG. The static closing force Fs fluctuates according to the pulling force F of the engine hood 1. To set the pulling force F of the spring 46 of the assembly device 4 to the lower limit within the reference range of the static closing force Fs in the figure, the pulling force is set. It suffices to set the force F to a preset F _min , that is, to change the setting of the spring 46 to a spring constant corresponding to F _min , and in this case, the engine hood 1 is securely closed while keeping the minimum value. The static closing force Fs can be used, and the stable quality can be secured by the assembly device 4 while improving the operability of the engine hood 1.

In the above-mentioned conventional example, since the mounting position of the hood lock 6 in the vertical direction of the vehicle body varies, the hood lock 6 cannot be mounted at a position where the closing static force Fs becomes the lower limit. On the other hand, suppressing the influence of the dimensional tolerance of the vehicle body
Since it is possible to stably attach the hood lock 6 to a position corresponding to the pulling force F given by the spring 46 of the assembling device 4, while setting the pulling force F to an arbitrary value,
Moreover, the hood lock 6 can be attached with stable quality.

Further, the hood lock 6 can be positioned in the vehicle width direction and the vehicle body vertical direction almost at the same time by the assembling device 4. Further, this positioning work is performed only by closing the engine hood 1 once. It is possible to shorten the time and further improve the productivity.

The mounting of the headlamp 5 is carried out almost at the same time as the mounting of the hood lock 6 of the first embodiment. Similarly to the above, the assembling device 4 is locked with the bracket 30 by the locate pins 49, 49 and the striker. The engine hood 1 is locked with the hood lock 6 via the valve 7.

In the locked state of the hood lock 6, as described above, the engine hood 1 is pulled downward by the spring 46 of the assembling device 4, and the front end of the center portion of the engine hood 1 corresponding to the mounting position of the striker 7 is pulled. Then, depending on the pull-in force F, both ends on the fender 2 side are displaced downward by Z _{3 in the} figure.

Here, the headlamp 5 is supported by the support arm 52.
Supported by the underside of the vehicle body of the headlamp 5
Among the mounting holes for inserting the bolts 5A protruding from the upper part, the upper part outside the vehicle body is used as the reference hole 51 for restricting the displacement in the vertical direction of the vehicle body, while the other mounting holes 50 allow the displacement of the bolts 5A. Together with the pulling force F of the spring 46
