The other end of the plate 160 protrudes outward through a hole 106a formed in the second side plate 106 and is coupled to a second pressing member (pressing mechanism) 162. The second pressing member 162 is the second claw piece 1
34 and is arranged and configured to be substantially symmetrical with the first pressing member 154.

The automobile door assembly device according to the present invention is basically constructed as described above, and its operation and effects will be explained next.

First, as shown in Fig. 3, the arm 2 is placed inside the door A to be assembled
8 are parallel to each other. Then, the first claw piece 132 at the tip of the arm 28 is attached to the door A.
The main body 20 and the arm 28 are stopped at a position where they can be fitted into the U-shaped hinge attachment coupling member 164 at the upper part of the body by simply moving in the Y-axis direction.

Next, the second claw piece 134 connects to a U-shaped hinge attachment connecting member 166 at the bottom of the door A.
The swinging motor 118 and the motor 136 are operated to position the oscillating motor 118 and the motor 136 so that it is oriented to a position where it can be inserted by movement in the Y-axis direction. Next, the motors 34 and 48 are driven to move the locking pin 52 to a position where it can engage the striker of the door A in the Y-axis direction. In this state, by moving the arm 28 in the direction of the door A, that is, in the Y-axis direction, the three points, the first claw piece 132, the second claw piece 134, and the locking pin 52, are connected to the connecting member 164 of the door A, 166 and the striker, respectively. Then, the cylinders 64, 64a of the first holding mechanisms 56, 56a are operated in the direction of the arrow shown in FIG. As a result, the connecting member 68,
68a swings around pins 78, 78a as fulcrums,
The suction cups 72, 72a attached to the tip of the door A
It moves in the direction of direction and ends up adsorbing on the window of door A.

On the other hand, the cylinder 8 of the second holding mechanism 80, 80a
8, 88a in the direction of the arrow, the connecting members 92, 92a swing about the pins 100, 100a via the cylinder rods 90, 90a. Accordingly, the clamp members 9 disposed at the respective tips
4, 94a swings to hold the lower edge of the door A.

The door A, which has been outfitted through the above operations, is held by the arm 28 of the automobile door assembly device.

Next, the main body 20 is moved and the pair of upper and lower coupling members 164, 166 of the door A are assembled to the pair of upper and lower coupling members 168, 170 on the vehicle body side. Then, in advance, the upper and lower mating coupling members 168, 1 on the vehicle body side are
Connecting pin 1 temporarily attached while being inserted into 70
72, 174 are press-fitted. That is, cylinder 1
48 to raise the cylinder rod 150, the first pressing member 1 is moved through the plate 152.
54 is moved upward, and the upper coupling pin 172 is press-fitted through the first pressing member 154. At the same time, the cylinder 156 is actuated to move the cylinder red 158 downward, thereby lowering the second pressing member 162 via the plate 160, and the second pressing member 162 pushes the lower coupling pin 174. Press fit to connect the vehicle body and door A.

Next, the respective holding mechanisms 56, 56a, 80,
The cylinders 64, 64a, 88, 88a of 80a are operated in the direction opposite to the arrow, and the holding mechanisms 56, 56
After releasing a, 80, 80a, arm 28
is moved in the opposite direction to the door A to separate it from the door A connected to the vehicle body. Then, the main body 20 is moved to its original position in order to perform the next stage of assembly work.

As described above, the device of the present invention is provided with a holding mechanism that can move to accommodate the difference in door shape caused by different models, and each holding mechanism can move the door after it has been rigged. The structure allows the door to be held in a position where it will not be damaged. Therefore, it can be easily applied to many types of doors.
It is ideal for automatic door assembly and has the advantage of further improving production efficiency. That is, the first claw piece 13 that fits into the upper coupling member 164 formed on the door A
2 as a reference, by operating the motor 136 to move the second claw piece 134 that fits into the lower coupling member 166 of the door A up and down, and on the other hand, by operating the swinging motor 118 to swing the housing 102. The second claw piece 134 is attached to the lower connecting member 166 of the door A.
At the same time, the motor 34 mounted on the upper surface of the arm 28 causes the sliding member 40 to slide left and right in FIG. 2, and the motor 48 mounted on one end of the sliding member 40 The locking pin support member 50 is moved up and down in FIG. 3 by driving. This therefore allows the locking pin 52 to be moved substantially in a plane and directed towards the striker of the door A. In the end, as described above, doors of various models with different shapes can be securely held by simply moving the first claw piece 132, the second claw piece 134, and the locking pin 52 to predetermined positions on the door. It is possible to do so.

On the other hand, the suction cups 72 and 72a that constitute the first holding mechanisms 56 and 56a are suctioned to the window portion of the door A. Since the window portion does not shift slightly even if the shape of the door is slightly different, it can be used for a variety of doors regardless of the type. In addition, the second holding mechanisms 80, 80a and the clamp members 94, 94a that actually come into contact with the lower edge of the door A also
Since the second holding mechanism 80, 80a does not need to be moved individually, the structure is further simplified compared to the conventional one.

As described above, according to the present invention, in the automobile door assembly device for attaching a door that has been outfitted to a vehicle body, the claw piece that engages with the coupling member of the door from the inside of the door and the striker of the door. The door is held by displacing a locking pin, and the holding operation is ensured by a suction cup that sticks to the window of the door and a clamp member that comes into contact with the lower edge of the door. ing. Therefore, since there is no abutment mechanism on the outside of the fitted door to hold it in place, this prevents damage to the paint film on the outside of the door, and also prevents damage to the door shape due to differences in models. This can be done with a simple operation of moving the holding mechanism. As a result, it not only has the advantage of being suitable for automating door assembly work and improving production efficiency, but also eliminates the need for jigs to hold doors with different shapes, which results in lower vehicle production costs. This also has the effect of making it possible to reduce the amount of water.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments, and various improvements and changes in design can be made without departing from the gist of the present invention. Of course.
