Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for assembling a damper in an automobile assembly process.

In the automobile assembly process, a damper to which a brake drum has been previously assembled is manually assembled onto a vehicle body. Assembling the damper and brake drum is a heavy item, so two people have to work together, but it is labor intensive and inefficient, so it was particularly avoided during assembly work.

Therefore, the present invention provides a semi-automated damper assembly method that can be performed by one person with light work.

That is, the means 2 for horizontally transporting the car body 1
and damper 4 with brake drum 3 assembled in advance.
a means 5 for conveying the damper 4 substantially horizontally; a vertically movable and rotatable transfer support means 6 for transferring and supporting the damper 4 from the damper transfer means 5; The damper was transferred to the transfer support means 6 by the means 7 for conveying it laterally parallel to the vehicle body conveyance and at right angles to the conveyance direction toward the vehicle body, and the weight of the transfer support means 6. The transfer support means 6 is provided with a balance cylinder 8 that can be switched according to the weight of the vehicle, and after the damper 4 that has been horizontally conveyed is transferred and supported while the transfer support means 6 is finely swung by a lever 65, the handle 66 A damper in an automobile assembly process, characterized in that the damper 4 is assembled to the vehicle body 1 by rotating the transfer support means 6 supporting the damper 4 to the vehicle body 1 while following the conveyance of the vehicle body 1 and moving it up and down. This is the assembly method.

The vehicle body conveying means 2 in the illustrated example includes a substantially horizontal guide rail 21 disposed on the lower surface of the ceiling, etc.
The vehicle body 1 is carried by the hanger 22 at a constant speed.

On the other hand, the damper conveying means 5 consists of a conveyor 51 that moves intermittently and a hanger 52 suspended from the conveyor 51 at a predetermined interval.
The conical spring receiver 41 of the damper 4 to which the brake drum 3 has been assembled in advance is supported by the forked hook 52a at the lower part of the damper.

The damper transfer support means 6 has an arcuate hook 61 for transferring and supporting the damper 4 on the conveying means 5, and a holder 62 for supporting the brake drum 3 from below.

Further, the means 7 for conveying the transfer support means 6 toward the vehicle body parallel to and perpendicular to the vehicle body conveyance direction includes a pair of fixed rails 7 disposed parallel to the conveyance direction of the vehicle body.
1, 71, and a pair of rails 72, 7 that move along the passing rail 71 between both rails 71, 71.
2, a horizontal rod 73 that moves on the moving rails 72, 72 in a direction perpendicular to the direction of movement thereof, and a vertical rod 74 that hangs down from the horizontal rod 73.

A cylindrical member 63 is fitted into the lower part of the vertical rod 74 so as to be vertically movable and rotatable, and the arcuate hook 61 is attached to the arm 64 integral with the cylindrical member 63 so as to be swingable about the horizontal shaft 61a. A swing operation lever 65 is integrally provided behind the arcuate hook 61, and a brake drum receiver 62 is attached to the lower part of the arcuate hook 61. Further, the arcuate hook 61 and the handle 66 for vertically moving and rotating the brake drum receiver 62 are provided integrally with the cylindrical member 63 via an arm 67.
Reference numeral 75 is a stopper that restricts the downward movement of the cylindrical member 63.

The balance cylinder 8 is held between upper and lower brackets 81 and 82 which are rotatably provided on the vertical rod 74, and the rod 83a of the piston 83 extends downward through the lower bracket 82 and projects from the cylindrical member 63. Connected to arm 68. Further, the lower bracket 82 is held between a circlip 84 provided on the vertical rod 74 and a stopper 85, and a protrusion 82a corresponding to the stopper 85 is provided on the lower bracket 82 to restrict rotation of the transfer support means 6.

The chamber 8a above the piston 83 in the balance cylinder 8 is open to the atmosphere, and a fluid such as compressed air at a pressure corresponding to the weight of the transfer support means 6 etc. is supplied to the lower chamber 8a from a fluid source 86 by fluid pressure switching. It is sealed via a mechanism 87. That is, when the damper 4 is not transferred to the transfer support means 6, a low-pressure fluid corresponding to the weight of the transfer support means 6 is filled to achieve balance. Further, when the damper 4 is transferred to the transfer support means 6, a high pressure fluid corresponding to the added weight is filled and balanced. As a result, the vertical movement and rotation of the transfer support means 6 can always be easily performed. Note that switching to the fluid pressure switching mechanism 87 described above is performed by a switching valve 88 provided on the handle 66.

To assemble the damper 4 to the vehicle body 1, use the handle 6
6, move the transfer support means 6 to the front of the damper 4 which has been intermittently conveyed by the conveyance means 5 and is stopped, move the arcuate hook 61 below the conical spring receiver 41 of the damper 4, and move the holder 62 to the brake. It is located below the drum 3. At this time, the fluid pressure within the balance cylinder 8 is maintained on the low pressure side.

Then, the fluid pressure in the balance cylinder 8 is switched to the high pressure side with the switch 88, and the lever 65 is swung for fine adjustment while pulling up the transfer support means 6 with the handle 66, and the conical spring receiver 41 of the damper 4 is moved to the arcuate hook. Reprinted on page 61. At this time, the arcuate hook 61 is formed larger than the forked hook 52a of the conveyance means 5 so as not to interfere with it.

Next, operate the handle 66 to move the transfer support means 6.
is guided to the vehicle body 1 side on the transport means 2, and the damper 4 is inserted into the inside of the vehicle body 1 by vertically moving and rotating the transfer support means 6. Then, the transfer support means 6 is moved to the vehicle body 1.
The damper 4 is assembled to the vehicle body 1 while being moved to follow the transportation of the damper 4.

Since the present invention has the above configuration, the handle 66
The damper transfer support means 6 is moved toward the conveyance means 5 by operating the handle 66 and the lever 65, and the damper 4 on the conveyance means 5 is transferred by operating the handle 66 and the lever 65. Means 6 to handle 66
It can be assembled by an extremely simple manual operation, just by operating the damper 4 and guiding it to the vehicle body 1 side, and assembling it while moving it together with the vehicle body 1, without having to lift the heavy damper 4 and brake drum 3 by hand. Assembling work can be done semi-automatically by one person, which reduces labor and greatly improves work efficiency.
