ている。2. Description of the Related Art Generally, a columnar member 11 and a flange member 1 are provided.
In the case where the workpiece 10 is temporarily welded to the temporary welding,
For example, as shown in FIG.
1 and a welding robot 92 are used.

により、ベース台71に対して強固に固定される。In this case, as shown in FIG. 7, a flange member 12 of a workpiece 10 is mounted on a base 71 mounted on a face plate 94 of a rotary table mechanism. Fastening bolt 73
As a result, it is firmly fixed to the base table 71.

る。[0004] As described above, the work piece 10 is moved to the positioner 9.
After being fixed to 1, welding is performed by the welding device 92 shown in FIG. 9, that is, by the appropriate relative movement between the welding torch 93 and the positioner 91. In this case, the free end side of the flange member 12 tends to bend upward due to the effect of welding heat input. So-called distortion is about to occur.

り、破壊したりすることがある。By the way, if the conventional work to be welded is mounted as shown in FIG. 7, the flange member 12 will be bent and deformed in addition to the fastening force when the work is fixed. Is applied to the clamp member 72 and the fastening bolt 73, and if the mechanical strength of the clamp member 72 and the fastening bolt 73 is not sufficient, the clamp member 72 and the fastening bolt 73 may be deformed or broken.

者に当たるなどの危険が伴っていた。[0006] Even when deformation or destruction does not occur, a large force due to the above-mentioned tightening force and bending deformation force acts on the fastening bolt 73, so that the fastening bolt 73 is loosened when the workpiece is removed after welding. However, a large torque is required, and workability is significantly impaired. Of course, since the large force acts as described above, the durability of the clamp member 72 and the fastening bolt 73 deteriorates. Further, when the fastening bolt 73 is loosened, the restrained strain is released, so that the fastening bolt 73 and the clamp member 72 jump up, and there is a danger of hitting an operator, for example.

3 to reduce the stress acting on the clamp member 72.
It is conceivable to increase the number of the fastening bolts 73, but such an increase in the number is not practical because the work of attaching and detaching the work to be welded becomes troublesome.

虞れがあった。When the tightening bolt 73 is loosened after welding, even if no distortion is generated, the distortion due to welding heat input is restricted by the clamp member 72 and remains in the flange member 12 as internal stress. For example, when a work to be welded is suspended by a crane and transported / placed to another location, an impact is applied to the work to be welded and internal stress is generated as a strain, and the work to be welded is unexpected. There is a risk that the shape will be deformed.

る。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. 1 to 3, reference numeral 10 denotes a workpiece to which a columnar member 11 and a flange member 12 are temporarily attached by tack welding, and 13 denotes a pedestal on which the workpiece 10 is mounted. It is formed movably in the Z direction with respect to the table 14. For example, guide members 15, 15,... Restrained by a base table 14 are integrally supported on the receiving table 13. The spring members 16, 16,... Are arranged between the receiving table 13 and the base table 14. 1
Reference numerals 7, 17... Denote clamp members for setting the position of the workpiece 10, the workpiece 10 being mounted on a cradle 13,
After the horizontal position of 0 is set, the workpiece 10 is pressed against the base 14 by the fastening bolt 18 via the receiving base 13 and the spring 16. That is, the clamp members 17, 17,... Pressing the workpiece 10 against the spring member 16 also serve to position the workpiece 10 in the horizontal direction. The spring member 16 has a spring force enough to press the workpiece 10 against the clamp member 17 while supporting the weight of the workpiece 10 and the weight of the cradle 13. The above-mentioned support 13 to the fastening bolt 18 constitute a workpiece support device 19.

を圧縮させる力が作用するに留まる。By the way, in the apparatus according to the present invention, as shown in FIG. 3, the flange member 12 is pressed against the base 14 by the clamp member 17 via the receiving base 13 and the spring 16, so that the flange member 12 If distortion occurs, based on the pressing surface of the clamping member 17, the cradle 13 the spring member 16 is compressed to move to the Z 1 direction. That is, the clamp member 17 and the fastening bolt 18
The spring member 16 accompanying the bending deformation of the flange member 12
The force of compressing only acts.

る。As described above, since excessive force does not act on the clamp member 17 and the tightening bolt 18, the clamp member 17 and the tightening bolt 18 do not break during welding. Of course, since the miss strain during welding Z 1 direction, when loosening the tightening bolt 18, without open state of the restraining distortion as the conventional occurring, thus easily performed Removing the object to be welded be able to. Moreover, since the receiving tray 13 with the distortion generation moves in the Z 1 direction, if constant welding conditions such as the size and welding enforcement order of welded object, the shape of the object to be welded after welding, almost desired It becomes the shape of.

Are divided into a plurality. Thus, the cradle 13,
If the parts 13 are divided, in order to adapt to the amount of distortion generated unevenly at various points of the flange member 12, even if the workpiece 10 becomes large, as shown in FIG. It can be stably supported.

材を設けることができる。When the workpiece 10 is placed on the base 14, it is necessary to position the workpiece 10 in the horizontal direction. It is necessary to move the workpiece.
For this reason, it is preferable to provide the receiving stand 13 with a means for reducing friction with the workpiece 10. As the friction reducing means, FIG.
4 and 4, the upper surface of the pedestal 13 is coated with a fluororesin, or as shown in FIG. 4, the pedestal 13 is curved, or as shown in FIG. A rotatable spherical receiver 131 can be provided at a contact portion with an object. Of course,
The friction reducing means makes it possible to easily move the workpiece during positioning. The clamp members 17, 17, which press the workpiece 10 against the spring member 16, are provided.
Has been described as also used for positioning the workpiece 10 in the horizontal direction, but a positioning member for positioning the workpiece 10 in the horizontal direction can be provided separately from the clamp members 17, 17,....

In other words, since the workpiece does not move away from the face plate of the positioner during welding, the workpiece does not approach equipment or workers located around the positioner during welding, and the equipment is damaged. There is no possibility that a secondary disaster of workers or workers will occur.

溶接物の形状はほぼ所望の形状となる。As is apparent from the above description, the device for supporting an object to be welded according to the present invention has a structure in which even if distortion occurs during welding, the pedestal releases the distortion. Further, an excessive force for restraining the strain does not act on the fastening bolt as in the related art. Therefore, the clamp member and the tightening bolt are not damaged during welding. Of course, since the distortion during welding is released, the release of the restraint strain does not occur when loosening the tightening bolt as in the past, so that the work to remove the workpiece can be easily performed. it can. In addition, since the position of the cradle is displaced due to distortion, if the welding conditions such as the dimensions of the workpiece and the welding order are kept constant, the shape of the workpiece after welding is almost the desired shape. Become.

る。Further, by dividing the pedestal into a plurality of parts, even if the work to be welded is distorted unevenly at various places, the position of the pedestal is appropriately displaced in accordance with the amount of distortion of each part, thereby enabling stable support. Become. Furthermore, if means is provided for reducing the frictional resistance of the surface of the pedestal on which the workpiece is to be contacted with the workpiece, movement of the workpiece for positioning on the cradle is easier than in the past. And workability can be improved.
