Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called angle material (canopy steel according to JIS G3192) in can manufacturing work.
The present invention relates to a jig for a right-angle welding work for welding a right angle to a corner of a right-angled bottom plate.

[0002]

2. Description of the Related Art FIG. 7 shows a conventional method for welding an angle member to the above bottom plate. When the angle member A is welded to the bottom plate B at a right angle, the angle member A is uprightly contacted with the right angle corner portion of the bottom plate B, and the right angle surface S1a of the two right angle squirts S1 and S2 (hereinafter simply referred to as squeezer). , S2a to the bottom plate B,
While maintaining a state in which the two side surfaces of the angle material A are in contact with each other, the welding location Z is appropriately welded by welding means.

[0003]

However, in this case, generally, the angle member A must be held at a right angle while holding the two square members S1 and S2 with the left hand, and the angle members A can be held at right angles. It is difficult to make a right-angled weld because there is a gap between the square member and the angle member, and since both hands are blocked, it is not possible to have a so-called light-shielding surface and to prevent the eyes from burning during welding. There was a problem such as being unable to monitor the welding location such as closing eyes.

In view of the above points, the present invention has an object to provide a jig for right angle welding of an angle member, which can accurately hold the right angle when performing the right angle welding of the angle member and can work with both hands. And

[0005]

A first aspect of the present invention for achieving the above-mentioned object is to cut a part inward at a right angle and to form a right-angled member to be welded (hereinafter referred to as a bottom plate) by the notch. ), A pedestal supporting the corners, a support rod vertically planted on the surface of the pedestal, and slidably inserted into the support rod,
It consists of a support member that inserts and supports the angle material to be welded, and the angle material insertion hole of the support member is formed in a position where the angle material that is inserted into this support and is held vertically is held vertically to the corner of the bottom plate. It is characterized by.

According to the present invention having the above structure, the angle member can be easily and easily held at right angles to the corner portion of the bottom plate.

The second invention is characterized in that the distance between the support rod and the notched end face of the pedestal and the distance between the support rod insertion hole and the angle member insertion hole of the support member are both zero. is there.

With the above construction, since the angle member can be brought into contact with the support rod, the angle member can be held vertically.

The third invention is characterized in that at least two supporting rods are provided at appropriate positions on the surface of the pedestal.

With the above arrangement, the angle member can be prevented from shaking even if there is a slight gap between the support rod insertion hole of the support member and the support rod.

A fourth aspect of the invention is characterized in that the supporting member is provided with a fixing means for fixing the angle member to the supporting member.

With the above arrangement, the support member can be fixed to the angle member at any position.

A fifth aspect of the invention is characterized in that the pedestal notch surface is provided with a suction means for attracting the bottom plate by a magnetic force.

In the case of the above construction, the bottom plate can be securely sucked and held by the suction means provided on the pedestal.

[0015]

1 to 4 show a first embodiment of the present invention. The jig 1 for right-angle welding has a pedestal 2 in which a notch 3 is formed by cutting a part of the jig 1 inwardly at a right angle, and is vertically planted in the pedestal 2 on both sides of the notch 3. Support rods 4a, 4b (hereinafter, simply referred to as 4) and an angle support member 5 slidably inserted in the support rod 4.
And Although the example in which the two support rods 4 are provided is shown in the illustrated example, the number may be one or three or more. However, the supporting member 5 to be supported is supported so as not to swing to the left and right.

It is preferable that the front surface of the pedestal 2 is parallel to the back surface, and the cutout surface 3a of the cutout portion 3 is a suction surface by magnetic force or the like. A known structure for switching between is shown. The cross-sectional shape of the support rod 4 can be various shapes such as a circle as well as a quadrangle.

The support member 5 is provided with a support rod insertion hole 7 and an insertion hole 8 for the angle member A, and the interval (a in FIG. 4) is
The distance is the same as the distance (b in FIG. 2) between the support bar 4 of the pedestal 2 and the cutout end surface of the cutout portion. As a result, the angle member A inserted into the insertion hole 7 of the support member 5 is attached to the base 2
It can be held vertically on the bottom plate B abutting on the notched surfaces 3a, 3a. Reference numeral 10 denotes a fixing means such as a bolt for fixing the support member 3 and the angle member A.

When various angle materials can be inserted into the angle material insertion hole 8, for example, when welding angle materials up to 50 mm square (usually the thickness is 4 to 6 mm), the dimension x in FIG. 4 is about 55 mm and y. Is about 7 to 8 mm, and when welding an angle member of 50 mm square or less, the fixing member 10 is screwed in to urge the angle member A toward the notch surface 11 side to prevent the bottom plate B and the angle member A from shifting. You can do it.

In the above structure, the bottom plate B as shown in FIG.
Is abutted against the cutout surface 3a of the pedestal 2 and is attracted by turning on the magnetic force changeover switch 7, and the angle member A is inserted into the supporting member 5, and the fixing means 1 for the supporting member 1 is attached.
The angle member A is fixed at a suitable position (preferably fixed at two positions above and below) by 0, and the angle member A is held at a right angle to one corner of the bottom plate B.

After that, the welded portion Z is welded by an appropriate welding means.

5 and 6 show another embodiment. In this embodiment, both a and b are set to 0. That is, the support rod 23 of the jig 20 for right angle welding of the angle member of this example is formed into a columnar shape, a part of which is inserted into the notch surface 22 of the pedestal 21 so as to project, and the protruding portion serves as the notch surface 24. Both the cutout surfaces of the pedestal 21 and the cutout surface are the same, and the insertion hole 26 of the support rod 23 of the support member 25 is also formed following the shape of the support rod, and the cutout surface 24 of the support rod 23 and the angle member insertion. The hole 27 is held on the same plane. Other structures are the same as those of the previous example, and the same components are denoted by the same reference numerals and description thereof will be omitted.

[0022]

As described above, according to the present invention, when the angle member is held at a right angle to the bottom plate, the angle member is held by a support member slidable along a support rod provided perpendicular to the surface of the pedestal. Therefore, it is possible to hold the angle accurately, and it is possible to use both hands during welding work because it does not require manual labor to hold that state, and it is possible to have a light-shielding surface in one hand. Does not close or burn eyes during work. When the distance between the support rod and the notched end face of the pedestal and the distance between the support rod insertion hole of the support member and the angle member insertion hole are 0, the angle member abuts the support rod, so that the angle member cannot be fixed. It can be done more reliably. Further, by providing at least two support rods, it is possible to prevent the support member from swinging and ensure the holding of the horn material. Further, when the means for fixing the angle member is provided on the support member, the angle member can be prevented from swinging and can be securely fixed and held to the bottom plate.
Furthermore, when a magnet or other attraction means is provided in the notch of the pedestal, the bottom plate can be easily fixed and held.
