Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a method for attaching and welding end plates to both end faces of a square cylindrical column base material. The present invention relates to an end plate setting device that sets end plates at a predetermined gap. It can be used to manufacture columns that make up the framework of housing units.

[Background technology]

The framework of the housing unit that makes up the unit house is constructed by welding beams to both ends of square cylindrical columns. At this time, end plates with the same shape as the end faces of the pillars are welded in advance to both end faces of the pillars in order to fix the unit house to the foundation etc. or to connect the upper and lower housing units to each other. things are being done.

Normally, when welding end plates to both end faces of a column, a bevel is formed in advance at the welded portion between both end faces of the column and the end plate. After that, set the end plates on both end faces of the column, and in this state, temporarily weld the end plates to the column from at least three of the four outer surfaces at each end of the column, and then A work procedure is adopted in which the parts are welded using a welding robot or the like.

By the way, when attaching the end plate to both end faces of a column, in order to accurately set the end plate in a state corresponding to both end faces of the column, it is necessary to position the column and the end plate in a predetermined position relative to each other. or is necessary.

Therefore, in the past, the column, which was carried in the longitudinal direction in a horizontal position (one outer surface of the square cylinder was horizontal), was first placed against the first stopper to position it in the longitudinal direction, and then Then, after pressing the end plate in the direction perpendicular to the axis of the column with a pusher and abutting it against the second stopper to position it in the width direction, the end plate, which is held in the same posture as the end face shape of the column, is pressed against the end face of the column. In this state, the end plate is temporarily welded to the column from the three outer surfaces of each end of the column.

[Problem to be solved by the invention]

However, in the conventional end plate setting method, the column is positioned in a horizontal position, so when positioning the column in the width direction, the column is pressed in a direction perpendicular to its axis and brought into contact with the stopper. This is necessary.

Moreover, since the positioned column remains in a horizontal position, it is extremely difficult for an operator to temporarily weld the end plate from the three outer surfaces of the column while remaining in a fixed position. For example, if a column is positioned in a horizontal position with the surface that will not be tacked facing downward, a worker may be asked to tack the front and top sides of the column, although welding can be done relatively easily. It is difficult to weld the back side of the tack because the welding is done from the operator to the back side across the column.

In addition, when welding the entire circumference of the end plate using a welding robot, in order to weld the end plate integrally and firmly to the column, it is necessary to prepare a bevel in advance at the welding part between the end plate and the end face of the column. Because it has to be
The disadvantage is that the number of processing steps increases.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate such conventional drawbacks, to provide a simple structure, and to allow an operator to easily temporarily attach an end plate from the 3 outer surfaces of a column base material while remaining in a fixed position. By making it possible to set the end plate to the column base material and the column base material in a position that allows welding, and to set the end plate to both end faces of the column base material with a predetermined gap between each member. An object of the present invention is to provide an end plate setting device that eliminates the need for beveling.

[Means to solve the problem]

Therefore, the end plate setting device of the present invention is an end plate setting device that sets end plates on both end faces of a square cylindrical column base material carried in with a predetermined gap between them, Adjacent 2 pillar base materials
A support mechanism that has an L-shaped support surface that fits the outer surface and supports the two outer surfaces in a tilted position with respect to the horizontal plane, and supports the column base material carried in in a longitudinal direction in a substantially horizontal position. A movable base is provided on both end sides of the column base material supported by this support mechanism so as to be movable in the axial direction of the column base material. A holding member that holds the end plate in a posture corresponding to the end face, and a spacing member that is interposed between the end plate held by each of the holding members and both end faces of the column base material and maintains a predetermined gap between the two. It is characterized by the following:

[For production]

The imported column base material is held in a position where two adjacent outer surfaces are inclined with respect to the horizontal plane by the L-shaped support surface of the support mechanism.
In addition, it is automatically positioned so that its longitudinal direction is substantially horizontal.

Here, each movable table is moved in the axial direction of the column base material while each holding member holds the end plate in a posture corresponding to the end surface of the column base material.

At this time, if a spacing member is interposed between the end plate and both end surfaces of the column base material, the end plates are set with a predetermined gap between them with respect to both end surfaces of the column base material.

Therefore, the column base material is positioned with two adjacent outer surfaces inclined with respect to the horizontal plane, and the end plates are set with a predetermined gap between both end surfaces of the column base material. The operator can easily tack weld the end plate to the column base material from the outer surface of the column base material while remaining in a fixed position without requiring beveling or the like.

Relief holes 1, 67, and 168 are punched out between the holes 4, 165, and 166, respectively, and a gripping hole 169 is punched out near the intermediate clamping piece 165.

The clamping pieces 164 and 166 are formed on the side 163A of the jig main body 163 opposite to the gripping hole 169 so as to face each other with a width dimension of the fitting frame 35B apart, and
The inner edge is shaped like an arc. Moreover, the holding piece 1
65 is formed between the clamping pieces 164, 166 at right angles thereto.

Therefore, the jig main body 1 is placed with the clamping pieces 164 and 166 on the lower side.
63 is inserted into the fitting frame 35B of the end plate 35, the three clamping pieces 164, 165, and 166 are fitted to three outer surfaces of the fitting frame 35B. At this time, the clamping pieces 165 are moved so that the clamping pieces 164 and 166 are shifted from the center position of the two outer surfaces of the fitting frame 35B into which the clamping pieces 164 and 166 are fitted, toward the outer surface where the clamping pieces are not fitted. The length dimension has been set.

Next, the operation in the end plate temporary attachment step 50 will be explained.

The column base material 31, which has been conveyed in the longitudinal direction in a horizontal position by the third conveyor conhair 49, is first transferred to the support mechanism 1.
It is supported by support members 133 31A and 131B. At this time, the pillar base material 31 has two adjacent outer surfaces or the support member 13.
The L-shaped support surfaces 133A and 133B of No. 3 automatically position the device in an attitude that is inclined with respect to a horizontal plane and in which the longitudinal direction is substantially horizontal. Therefore, the clamp member 13
5 is rotated about the pin 134 to clamp the column base material 31 from above.

Next, the guide pins 146 of the pin mounting plates 145, 155 of each end plate setting mechanism 141, 151.

The three clamping pieces 164, 165, and 166 are in a state fitted to three outer surfaces of the fitting frame 35B.

Thereafter, when the movable bases 144 and 154 of each end plate setting mechanism 141 and 151 are advanced toward the end face of the column base material 31, the fitting frame 35B of the end plate 35 is fitted into the end of the column base material 31. At the same time, the end plate 35 of the end plate 35 is placed on both sides of the end plate temporary attachment jig 161.
A is brought into contact with the end surface of the column base material 31. In other words,
A gap 162 between the end plate 35A of the end plate 35 and the end surface of the column base material 31 is maintained at a predetermined gap by the thickness of the jig main body 163 of the end plate temporary attachment jig 161.

In this state, the end plate 35 is temporarily welded from three locations on the outer peripheral surface of the column base material 31. At this time, as shown in FIG. 12, the end plate temporary attachment jig 161 has an escape hole 167 between the adjacent clamping pieces 164 and 165°166.
．． 468 are formed, these escape holes 167
．． From 168 onwards, temporary attachment can be done by welding. Moreover, as shown in FIG. 14, since the three outer surfaces of the column base material 31 face the worker, the worker can easily perform tack welding while remaining in a fixed position, and the welding head can be directed downward. You can do it while you are doing it.

Therefore, according to this embodiment, the column base material 31 carried in is
By the support mechanisms 131A and 131B, the column base material 31 is automatically positioned in an attitude in which the two adjacent outer surfaces are inclined with respect to the horizontal plane, and in a longitudinal direction or in a substantially horizontal attitude.
Easy mechanism for positioning. In other words, it has the advantage of not requiring a conventional pusher or the like.

Furthermore, movable bases 144 and 154 that are movable in the axial direction of the column base material 31 and pin attachments attached to each of the movable bases 144 and 154 are provided on both end sides of the column base material 31 supported by the support mechanisms 131A and 131B. Since the end plate setting mechanism 141, 151 consisting of the plates 145, 155 is arranged, the end plate 35 is held on each pin mounting plate 145, 155 in a posture corresponding to the end surface of the column base material 31,
In addition, with the end plate temporary attachment jig 161 inserted into the fitting frame 35B of the end plate 35, the movable base 144,
If the end plate 154 is moved toward the end surface of the column base material 31 and brought into contact with it, the end plate 3
5 can be set accurately with a predetermined gap between them.

In addition, the end plate temporary attachment jig 161 is attached to a jig body 163 having a thickness corresponding to the gap between the end plate 35A of the end plate 35 and the end surface of the column base material 31, and the fitting frame 35B of the end plate 35. Three clamping pieces 164, 165 that fit on three of the four outer surfaces of the. Relief hole 1 is provided between adjacent clamping pieces 164, 165 and 166, leaving 166.
67 and 168, the gap between the end plate 35A of the end plate 35 and the end surface of the column base material 31 is maintained at a predetermined gap around the entire circumference by the three clamping pieces 164, 165, and 266. In addition, the end plate 35 can be temporarily welded to the three outer surfaces of the column base material 31 through the escape holes 167 and 168.

In addition, when temporarily welding the end plate 35 set on the end face of the column base material 31, the three outer surfaces of the column base material 31 face the worker, so the worker remains in a fixed position.
The tack can be easily welded or welded to two tack positions. Moreover, since these three temporary welding operations can be performed with all welding heads facing downward, the quality can be stabilized.

Note that the present invention is not limited to the above-described embodiments, but also includes the following modifications.

For example, the inclination angles of the support surfaces 133A and 133B that support two adjacent outer surfaces of the column base material 31 are not limited to the angles described in the above embodiments. In short, any angle may be used as long as the two adjacent outer surfaces of the column base material 31 that have been brought in are automatically positioned in a tilted attitude with respect to the horizontal plane.

In addition, in the above embodiment, each end plate setting mechanism 1

Although the movable bases 144 and 154 are moved in the axial direction of 1, the movable bases 144 and 154 may be automatically moved by a driving means such as a cylinder.

Further, in the above embodiment, the end plate 35 is connected to the guide pin 145. 14f3,155. Although the L56 is used to hold it in a predetermined position, it may also be configured using a member made of a permanent magnet.

〔Effect of the invention〕

As described above, according to the present invention, the column base material and the column can be easily welded with a simple structure, and the end plates can be easily tack welded from the three outer surfaces of the column base material while the operator remains in a fixed position. Since the end plates can be set to the base material and furthermore, the end plates can be set to both end faces of the column base material with a predetermined gap between them, it is possible to eliminate the need for beveling each member.
