Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work assembling apparatus for assembling, for example, a main body of an automobile, and more particularly to an apparatus for improving productivity and reducing equipment cost.

[0002]

2. Description of the Related Art A conventional automobile body assembly line includes a positioning stage for positioning various works to be assembled at an assembly position, a positioning welding stage for spot welding the positioned works, and a spot welding additional striking stage. It has a large number of stages for assembling the vehicle body, and is designed to perform the work specified for each stage.

FIG. 6 is a plan view showing a schematic structure of a conventional work assembling apparatus 10. This work assembly device 10
To assemble the main body of a car,
A floor main serving as a base of the body is received from a drop lifter (not shown), and set on a floor holding unit that holds the floor main of the first receiving stage 11. A rear panel forming a side wall of the rear portion of the vehicle body is supplied from the loader 33, and is laid down on the back so as not to drop on the fingers behind the floor main in the transport direction. Then, in this state, it is conveyed to the second receiving stage 13, receives the body side constituting the side walls on both sides of the vehicle body from a drop lifter (not shown), and performs positioning welding with the floor main. Further, in the second receiving stage 13, the cowl & dash and the rear waist & parcel, which are also called air boxes, are supplied from the loaders 31 and 32, respectively.

Next, the work is conveyed to the first positioning welding stage 26, and the positioning welding of the above various works is performed. Here, as described above, the rear panel is placed and conveyed on the finger behind the other work such as the floor main, and the positioning means 34a, 34 are fed from the finger.
Handed over to b. Then, the rear panel is rotated and positioned in a substantially upright position by the operation of the positioning means 34a and 34b arranged one by one on the left and right sides in the carrying direction, and then, together with other works. Positioning welded.

The first positioning welding stage 26 is composed of three stages 15, 16 and 17, and is applicable to three types of old and new model vehicles. In addition, the replacement stages 15a and 16 are provided in the respective stages.
a and 17a are attached. Therefore, if there is a stage that requires accurate positioning welding,
After adjusting the accuracy of the positioning welding means for the work outside the normally operating assembly line, the first positioning welding stage 26 moves from the replacement stage in a relatively short period of time.
It is possible to add positioning welding means after adjusting the accuracy.

When the positioning welding in the first positioning welding stage 26 is completed, the welding is carried to the additional-injection stage 18 and the additional welding in the spot welding is performed by the welding robots 35 ... Next, it is conveyed to the third receiving stage 21, and the loader 36 supplies the roof constituting the ceiling wall of the vehicle body. Then, after the positioning welding of the roof and the like is performed on the second positioning welding stage 27, the roof is carried out from the carrying-out stage 25 by a drop lifter (not shown). In addition, the second positioning welding stage 27,
Similar to the first positioning welding stage 26, it is composed of three stages 22, 23, 24, and replacement stages 22a, 23a, 24a are additionally provided.

[0007]

However, in the conventional work assembling apparatus 10 shown in FIG. 6, first, the floor main is set on the floor holding means, and the body side,
Since the spot welding is performed while sequentially positioning the air boxes, and so on, the stages to be positioned and welded are mainly dispersed in three places as shown in the figure. In particular, the second receiving stage 13 Since there is no backup for the positioning welding means used in, the accuracy adjustment of jigs and the like used for positioning welding cannot be done while the assembly line is in operation, and it is unavoidable to spend time on holidays.

Further, even in the first and second positioning welding stages 26 and 27, the accuracy adjustment performed by the backup stage attached to each of them is usually performed while assembling various works on the temporary lifter. The conditions are slightly different from those in the line. Therefore, the precision adjustment is difficult, and there is a case where readjustment is required after the line is put into a normal line.

Further, the rear panel has a substantially plate shape, is carried to a welding position while being placed on a carrying means, and is rotated and positioned by the operation of the positioning means 34a, 34b. Therefore, from the necessity of preventing the deformation, it has been necessary to provide high-cost equipment capable of operating both of the positioning means 34a and 34b in a precisely synchronized manner. In this case, it is conceivable to position the rear panel by a robot, but introducing a dedicated robot for this purpose leads to an increase in equipment cost.

The present invention has been made in view of the above-mentioned problems of the prior art, and improves the productivity by surely and promptly adjusting the accuracy of the positioning welding means in the work assembling apparatus, and reduces the equipment cost. The purpose is to reduce.

[0011]

Further, it has a supporting portion for supporting the lower end of a predetermined work and a rotatably holding portion for pressing the work from the side, and after receiving the work, it has a predetermined position and posture. The work holding means for holding the work is provided on the conveying means.

[0013]

In the present invention thus constructed, a plurality of works are sequentially supplied and are carried by the carrying means toward the assembly work stage. Next, the positioning and welding means provided in this assembly work stage performs the positioning and welding of all the supplied works at once. Here, on the guide rail extending from the conveying means in a direction orthogonal to the conveying direction of the work and laid, a replacement positioning welding means is movably provided,
The positioning and welding means is precision-adjusted separately from the main line production, and is slid on the guide rails and put into the main line in a short time without being disassembled as it is when necessary. As a result, it is possible to accurately and promptly perform the production using the positioning welding means whose accuracy is adjusted.

Further, it has a supporting portion for supporting the lower end of a predetermined work and a rotatably holding portion for pressing the work from the side, and after receiving the work, it has a predetermined position and posture. Since the work holding means for holding the work is provided on the carrying means, it is possible to hold the work so as not to drop it, carry the work in the final assembled state, and carry out the welding work in that posture.
