[0002]

2. Description of the Related Art The related art relating to this is the actual Kaihei 3-7.
No. 090 publication. This technique relates to a device for assembling an engine, a suspension and the like to a vehicle body, and FIG. 6 shows an outline of the device in a front view. This apparatus includes a positioning elevating mechanism 10 which positions a jig pallet 8 on which the engine 6 and the suspension 4 are mounted at a prescribed position and elevates the jig pallet 8. The positioning elevating mechanism 10 is installed in a state where the center line is aligned directly below the line for suspending and transporting the vehicle body 2 by the hanger 3. In addition, the positioning lifting mechanism 10
An elevating table 12 on which the jig pallet 8 is placed is provided, and a robot 14 for horizontally positioning the upper end of the shock absorber 4s is installed at both ends of the elevating table 12.

When the vehicle body 2 is conveyed by the hanger 3 right above the positioning elevating mechanism 10, the conveyance line is stopped and the vehicle body 2 is positioned. Next, the engine 6 and the suspension 4 on the jig pallet 8 are positioned by the positioning lifting mechanism 10 so as to have a specified positional relationship in the horizontal direction with respect to the vehicle body 2. Further, the upper end of the shock absorber 4s is horizontally positioned by the robot 14. Next, the elevating table 12 is raised, and the engine 6, the suspension 4, etc. are assembled to the vehicle body 2. Here, the shock absorber 4
Since the robot 14 positions the upper end of the shock absorber 4 in the horizontal direction, the shock absorber 4s and the vehicle body 2 do not interfere with each other when the lifting table 12 rises, and the upper end of the shock absorber 4s is the vehicle body. It is smoothly inserted into a mounting hole (not shown) formed in 2.

[0004]

However, according to the above-mentioned conventional apparatus, since the robot 14 is used for positioning the upper end portion of the shock absorber 4s, there is a problem that equipment cost increases. Further, the shock absorber 4s is swung or the like so that its position is changed to the lifting table 12
When the robot 14 deviates from the above predetermined position, the robot 14 may not be able to grip the shock absorber 4s, and there is a problem that the assembly reliability is poor. The technical problem of the present invention is to guide the upper end portion of the shock absorber 4s to the mounting hole of the vehicle body 2 by the guide member, thereby eliminating the need for using a precision machine such as the robot 14 and reducing the equipment cost. It is intended to reduce the reliability and further improve the reliability in assembling the shock absorber 4s.

[0005]

The above-mentioned problems can be solved by a vehicle suspension assembly device having the following features. That is, the suspension assembly device for a vehicle according to the present invention supports the rod-shaped member forming a part of the suspension in an upright state, and the upper end of the rod-shaped member is horizontally displaceable within a predetermined range. A suspension assembly of a vehicle in which the rod-shaped member is relatively moved in a height direction with respect to a vehicle body suspended above to insert the upper end portion of the rod-shaped member into a mounting hole formed in the vehicle body from below. In the device, the inclined surface formed in a substantially cone shape is provided, and when the rod-shaped member and the vehicle body approach each other, a guide member that guides the rod-shaped member by the inclined surface, and the rod-shaped member is the guide. The guide member is regulated with respect to the vehicle body so that the upper end of the rod-shaped member is guided by the inclined surface of the member and is inserted into the mounting hole formed in the vehicle body. And a guide member positioning mechanism for positioning the position.

[0006]

According to the present invention, first, the guide member positioning mechanism positions the guide member with respect to the vehicle body in a prescribed positional relationship. In this state, when the upper end portion is erected horizontally so that the rod-shaped member approaches the vehicle body from below, the rod-shaped member comes into contact with the substantially conical inclined surface of the guide member, and Follow it and move. As a result, the upper end of the rod-shaped member is guided to the mounting hole formed in the vehicle body. With this structure, even if the upper end portion of the rod-shaped member is not accurately positioned directly below the mounting hole formed in the vehicle body, the rod-shaped member will not be accurately positioned in the process in which the rod-shaped member approaches the vehicle body from below. The insertion locus is controlled by the member, and it is surely guided to the mounting hole of the vehicle body. That is, since the positioning accuracy of the upper end of the rod-shaped member may be rough to some extent, it is not necessary to accurately position the horizontal position of the upper end of the rod-shaped member by a robot or the like as in the conventional case. By adjusting the inclination of the inclined surface of the guide member and the height of the cone shape, the upper end of the rod-shaped member can be guided to the mounting hole of the vehicle body from a wide range.

The absorber guide mechanism 130 attached to the lower side of 24 is positioned at substantially the same position as the wheel arch 2h of the vehicle body 2 suspended on the hanger 3 in the line traveling direction (L axis direction). Then, the carriage 124 and the absorber guide mechanism 130 can move in synchronization with the hanger 3 and the vehicle body 2.

Here, the absorber guide mechanism 130.
The ascending / descending cylinder 134 has already been driven in the direction in which the piston rod is extended, and the movable mount 136 has descended obliquely. When the dolly 124 is connected to the hanger 3 by the connecting mechanism 150, the horizontal cylinder 138 of the movable mount 136 is actuated in the direction in which the piston rod extends and the absorber guide 140 causes the wheel arch 2h of the vehicle body 2 to move. It is stored inside. In this state, the elevating cylinder 134 is driven in the direction for accommodating the piston rod, and the movable mount 136 rises diagonally, causing the absorber guide 14 to move.
As shown in FIG. 1, 0 is an absorber mounting hole 2x formed in an upper portion of the wheel arch 2h of the vehicle body 2.
Is positioned at a prescribed position below. That is, the absorber guide 140 corresponds to the guide member of the present invention, and the lifting cylinder 134, the horizontal cylinder 138 and the like of the absorber guide mechanism 130, the carriage 124, and the connecting mechanism 150 correspond to the guide member positioning mechanism of the present invention.

Next, the function of the vehicle suspension assembly apparatus 100 according to this embodiment will be described. First, as shown in FIG. 4, the jig pallet 8 on which the engine 6, the suspension 4, etc. are mounted is mounted on the lifting table 118 of the positioning lifting mechanism 110. Here, the shock absorber 4s constituting the suspension 4 is connected to the suspension arm 4r via a bush 4b, and its upper end is supported so as to be horizontally displaceable within a predetermined range in an upright state. There is. Further, the tip of the shock absorber 4s is covered with a resin-made guide cap 4k formed in a substantially conical shape. Since the guide cap 4k is fitted to the tip of the shock absorber 4s by the spigot structure, the misalignment between the two is prevented.
It is secured to 0.5 mm or less. The lifting table 118
When the vehicle body 2 suspended by the hanger 3 reaches a predetermined position above the positioning elevating mechanism 110 with the engine 6 and the like mounted on the hanger 3, the carriage 112 of the positioning elevating mechanism 110 is connected to the hanger 3 by the connecting mechanism. To be done. Further, the elevating cylinder of the positioning mechanism 115 is operated, and the positioning pin 115p is inserted into the through hole 3k of the hanger 3 and the positioning hole 2k of the vehicle body 2 to move the dolly 11
2 is positioned so as to have a predetermined positional relationship with the hanger 3 and the vehicle body 2. As a result, the lifting table 1
The engine 6, the suspension 4, and the like on 18 are also positioned so as to have a predetermined positional relationship with the vehicle body 2.

At the same time, the absorber guide mechanism 130
The connecting mechanism 150 of the carriage 124 supporting the carriage 124 is operated and the grip portion 156 grips the hanger 3, whereby the carriage 124 and the hanger 3 are connected to each other. As a result, the absorber guide mechanism 130 is positioned substantially at the same position as the wheel arch 2h of the vehicle body 2 in the line traveling direction (L axis direction). Here, as shown in FIG. 3, the lifting cylinder 134 of the absorber guide mechanism 130 supported by the carriage 124 is already driven in the direction in which the piston rod is extended, and the movable mount 136 descends obliquely. There is. In this way, when the positioning elevating mechanism 110 and the carriage 124 move in synchronization with the hanger 3 and the vehicle body 2, the horizontal cylinder 138 of the moving mount 136 is actuated in the direction in which the piston rod extends and the absorber guide moves. 140 is housed in the wheel arch 2h of the vehicle body 2. In this state, the lifting cylinder 134
Is driven in a direction in which the piston rod is housed, the movable mount 136 is diagonally raised, and the absorber guide 140 defines the lower portion of the absorber mounting hole 2x formed in the upper portion of the wheel arch 2h, as shown in FIG. Be positioned in position.

When the absorber guide 140 is positioned at the specified position, the lift cylinder 116 of the positioning lift mechanism 110 operates and the lift table 118 moves up. Then, in the process of raising the elevating table 118, as shown in FIG. 1, the guide cap 4k put on the tip of the shock absorber 4s contacts the inner wall surface of the absorber guide 140, and the absorber guide 1
Ascended while being guided by 40. Then, while a part of the shock absorber 4s is in contact with the inner wall surface of the absorber guide 140, the tip of the guide cap 4k is inserted into the absorber mounting hole 2x of the vehicle body 2. Then, in this state, the elevating table 118 further rises, so that the guide cap 4k is inserted to the depth of the absorber mounting hole 2x following the absorber mounting hole 2x. A bolt hole 2n is formed near the absorber mounting hole 2x, and when the guide cap 4k is inserted into the absorber mounting hole 2x, the fixing bolt 4b of the shock absorber 4s is inserted into this bolt hole 2n. It Here, since the guide cap 4k is formed in a substantially conical shape, the guide cap 4k
Even if the center line of the guide cap 4k does not coincide with the center line of the absorber mounting hole 2x, if the tip of the guide cap 4k is inserted into the absorber mounting hole 2x, the guide cap 4k surely enters the inside of the absorber mounting hole 2x. .

When the engine 6 and the suspension 4 are mounted on the vehicle body 2 in this way, the lifting cylinder 134 of the absorber guide mechanism 130 is driven in the direction in which the piston rod extends, and the absorber guide 140 is moved to the position shown in FIG. At the bottom right of the horizontal cylinder 1
34 is driven in the direction in which the piston rod is housed, and the absorber guide 140 is returned from the inside of the wheel arch 2h of the vehicle body 2 to a position where it does not interfere with the vehicle body 2 and the hanger 3. Next, the connection mechanism 150 is operated to release the connection between the carriage 124 and the hanger 3, and the carriage 124 travels by itself to return to the original position. Further, the lifting table 118 and the positioning mechanism 115 of the positioning lifting mechanism 110.
Pin 115p of the vehicle is lowered, and the coupling mechanism is actuated to release the coupling between the carriage 112 and the hanger 3, whereby the positioning lifting mechanism 110, the hanger 3, and the vehicle body 2 are released.
The connection with is released. And the positioning lifting mechanism 1
10 is returned to its original position.

As described above, according to this embodiment, the upper end portion of the shock absorber 4s has the absorber mounting hole 2x.
Even if the shock absorber 4s is not accurately positioned right below, since the insertion trajectory of the shock absorber 4s is controlled by the absorber guide 140, the shock absorber 4s is reliably guided to the absorber mounting hole 2x. That is, since the positioning accuracy of the upper end portion of the shock absorber 4s may be somewhat rough, it is not necessary to accurately position the upper end portion of the shock absorber 4s using a robot or the like as in the conventional case. Therefore, the equipment cost is reduced, and it is not necessary to consider measures against robot runaway. Moreover, since the engine 6 and the suspension 4 can be mounted on the vehicle body 2 while moving the vehicle body 2 along the vehicle body transport line, the operating rate of the vehicle body transport line is improved.

[0018]

According to the present invention, a structure is adopted in which the upper end of the rod-shaped member is guided to the mounting hole formed in the vehicle body by the guide member having a substantially cone shape. Therefore, unlike the conventional case, it is not necessary to accurately position the upper end portion of the rod-shaped member by a robot or the like, and the equipment cost can be reduced. Also, the reliability of the equipment is improved.
