Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an automatic transmission system and an automatic transmission system.
Automotive under 7 that can be used in combination with II connection equipment and other jigs
Concerning an automatic assembly machine for four-body bodies.

The automobile underfront podium consists of a front winder panel, four radiator panels, and two radiator supports. In the conventional assembly of four underbody bodies, the transportation and positioning of each component was not fully automated and some of it was done manually. If there is a manual part, automation by welding robots etc. will be controlled to reduce work efficiency and safety, and this will cause a deterioration of work efficiency, which is natural for this company.

Accordingly, the object of the present invention is to improve the under-duff body of an automobile.
There are H and K that provide configurations that allow fully automatic assembly.

To clarify the following with reference to the drawings, Fig. 1 schematically shows the automatic assembly machine of the present invention when viewed from the top, and A is a pair of 7's.
Wantofender Epoon, B is radiator support, C
1 shows the D Va 11 panels, respectively. 1 The underbody parts are also assembled in the stage shown in (A), and D
In the assembled state, it is transported to the next stage indicated by (b). As indicated by the hint seen from the side, 1 to 0
The 7 elements are sent to the over conveyor IOK, which will be described later, and then sent to the assembly stage C through the route indicated by the arrows Jt-Js-Js. Radiator support B
is sent to the assembly stage K)K as shown in 14 from the swing-type conveyor fK of 30. In addition, the dasha panel C is
It is conveyed by the overhead conveyor 50 as shown by the arrow,
Move the swing type conveyor 40 to the assembly position (as shown by arrow 1.
).

The front 7 ender parts, radiator support B, and dash panel CO parts set in this way are welded (p) 10, 12.14# automatic welding device 16.18K
It is then welded.

FIG. 3 shows an overhead conveyor 20 for transporting the front 7 ender apron. A cart 202 is provided on a 7L/- frame 201 so as to be horizontally movable by a motor 203 and a chain 204. A hanger 205 is suspended from the platform 202 by a cylinder 206.

The hanger 206 has a plurality of pairs of 20 grippers, and the cylinder 2
It can be opened and closed by 08) and 7a and 7a can be used to attach and remove the ender apron.

Next, FIG. 4 shows the swing conveyance device 30 for the radiator support B, in which the holding plate 301, which is rotatable around the horizontal axis 300, is stopped at the holder 302 (not normally held), and is driven by the cylinder 303 as shown in the arrow. ! It can be rotated to the imaginary upright position as shown in 4. A stand 3 that pivotally supports one end of the plate 301
04 can be horizontally moved on the pace 305 by the 7 ring 306 as shown by the arrow.

Figure 5.6 shows the swing conveyance device 40 for Dalasi Island Panel C.
, a plate 40 that can be rotated by rotation of a vertical axis 401.
2, by the presser cylinder 403K, the Darashi Todoroki panel C
hold. Latch member 404 is always present.

At this time, the swing plate 402 is held at the standby position WIK in contact with the stopper 405. Reference numeral 406 is a driving cylinder that disengages the latch 404 from the plate 402, and allows the plate 4020 to rotate as shown by arrow J.

The overhead conveyor 50 for conveying the fyV & panel C is structurally similar to the overhead conveyor 20 for conveying the front fender nibling shown in FIG. 3, so the electrical circuit is shown.

Also, 2nd v! JKtiP1n, 6G is an under-duff Hy) assembled according to the present invention in the %l'QO f-scene.
The transfer cover used to transport the body to the next stage is shown, but a transfer bar known as a transfer bar can be used. Alternatively, a belt-type transfer device may be used.

Describing the operation below, the 7-ender Epsin A is mounted on the hanger 20 by the cylinder 206 from above the 311th assembly table 90.
5 and drives the cylinder 208 to release the gripper 20.
7 and grab work A. The primary motor 20 raises the hanger 205 in the direction of the arrow to the right using the cylinder 206.
3, the cart 202 is driven forward as shown by the arrow J, and then the hanger 205 is lowered as shown in 1.0, the gripper 207 is released, and the workpiece A is moved onto the stain mark.

Radiator sabot) B is the stand 30 that is attached to the cylinder 308.
1 is held above. Drive the cylinder 303 to
01 to the imaginary line position 1. After that, the workpiece is moved forward through the cylinder 306 to a predetermined position t.

The spring pwcli assembly 94 is transported to the overhead conveyor 50 in a standby position on the 15110th machine 402. It is then held on the stand 402 by a cylinder 403K. next? /9 Drive the latch plate 406
4, and then move the stand 402 along the cylinder 408 and rotate it as indicated by the arrow 1.

Next, automatic welding is performed using the welding device 16°18, and the underfront poday O
Perform assembly.

Finally, the assembled song body D is sent to the next stage by the transfer device 604-.

As described above, according to the present invention, the assembly of the under 7a topody can be fully automated, resulting in high work efficiency and the effect of suppressing one quality variation.
