Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] When a workpiece fixing tool, for example, a component such as a block having a through hole is fixed to a workpiece by welding, ensure that the workpiece is in contact with the workpiece during welding. Regarding a spring-type simple fixture that can be held, when welding an object to be welded, it is possible to reliably hold the object to be welded during the entire welding process, and it does not hinder the welding. For the purpose of providing a workpiece fixing tool that can be easily attached and detached, a workpiece having a through hole is welded to the workpiece while the through hole is aligned with the hole of the workpiece. A jig used in this case, the fixture is a substantially semi-circular frame, one end of which is connected to a spring attachment portion of the frame and the other end of which is connected to a spring connecting rod and a pin to the spring connecting rod. It consists of a press fitting that is rotatably provided in the center, When fixing the object to be welded, pass the straight pressing metal fitting and the spring connecting rod through the hole of the work and the through hole of the object to be welded arranged on the work,
When the holding metal fitting is completely out of the through hole, the holding metal fitting is laid down and the work piece is swung, and then the frame is raised and the work piece is brought into contact with the work piece by the spring. It is configured to include a workpiece fixing tool.

[Industrial applications]

The present invention is a spring type device capable of securely holding a workpiece to be held in contact with a workpiece during welding when a workpiece fixture, for example, a component such as a block having a through hole is fixed to the workpiece by welding. Related to simple fixtures.

[Conventional technology]

For example, a case on which a heavy device is placed (hereinafter, simply referred to as a work) is convenient for moving the case when a caster is attached to the work. Therefore, a block having through holes formed at four places of the work is used. It is fixed and the casters are attached to this block. Referring to FIG. 3, 11 is a work and 12 is an object to be welded (a block provided with a through hole). The part shown with sand in the figure is welded to fix the object to be welded 12 to the work 11. . The work piece 12 has
A through hole 12a is formed, and this through hole 12a is used for the work 11
Corresponding to the hole (not shown).

[Problems to be solved by the device]

At the time of the above-mentioned welding, according to the conventional technique, the workpiece 12 is to be worked by using the hand vice 21 shown in FIG.
Abut 11 At the time of work, in order to prevent the hand vice 21 from being welded, the hand vice 21 causes the work 12 to be in contact with the work 11 and the work to be welded 2 to 2
Only the three places are welded to prevent the work piece 12 from moving, the hand vise 21 is removed, and then the work piece 12 is fixed to the work piece 11 by a complete welding operation. As described above, there has been a problem in that the hand vise becomes an obstacle during welding of an object to be welded, and the time required to complete the welding is long because the hand vise is removed.

Therefore, the present invention makes it possible to reliably hold the object to be welded during the entire welding process when welding the object to be welded, and does not interfere with the welding, and is easy to attach and detach. The object is to provide a fixture.

[Means for solving the problem]

The above-mentioned problem is a jig to be used for welding an object to be welded having a through hole to a work in a state where the through hole is on the same line as the hole of the work, and the fixture is a semicircle. An annular frame, one end of which is connected to a spring mounting portion of the frame and the other end of which is composed of a spring connected to a spring connecting rod and a holding metal member which is rotatably provided on the spring connecting rod about a pin. When fixing, press the straightened metal fitting and spring connecting rod through the hole of the work and the through hole of the workpiece to be welded on the work, and press the work clamp when it is completely out of the through hole. The object to be welded is characterized by having a structure in which a metal fitting is laid down and the object to be welded is swung, and then a frame is raised so that the object to be welded is brought into contact with a work by a spring.

[Action]

That is, the present invention keeps the periphery of the welded part of the welded object so as not to interfere with the welding and strongly holds the welded object in contact with the work by a spring. The object of the present invention is to provide a fixing tool which can be simply carried out by simply tilting the frame.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

FIG. 1 is a front view of an embodiment of the present invention, 13 is a fixture according to the present invention, 14 is a holding metal fitting, 15 is a spring, 16 is a pin, 17 is a weight, 18 is a spring mounting portion, 19 is a spring connection The bar, 20 is the frame of the fixture.

With the fixture 13 not attached to the work 11, the work piece 12 is arranged on the work 11 with the through hole 12a of the work piece and the hole 11a of the work aligned on the same line, and the fixture 13 is attached. When held upside down from the state shown in FIG. 1, the holding metal fitting 14 is positioned on the same line as the spring connecting rod 19 connected to one end of the spring 15 with the fixed portion of the weight 17 facing downward. At that time, the frame 20 of the fixture (this frame has a semi-circular ring structure) is placed 90 ° forward or backward from the state shown in the drawing, and the weight of the upright holding bracket 14 is placed.
First, the portion to which 17 is fixed is passed through the hole 11a formed in the work 11 together with the spring connecting rod 19 and the hole 12a of the object to be welded, and the holding metal fitting 14 is completely brought out of the hole 12a. Here, the holding metal fitting 14 is rotated 90 ° about the pin 16 and the holding metal fitting 14 is arranged above the workpiece 12 as shown. Next, when the frame 20 is rotated 90 ° and raised to the state shown in the figure, the spring 15 connected to the frame 20 by the spring mounting portion 18 makes the pressing metal fitting 14 contact the work piece 12 and thereby the work piece 12 to be welded. The work piece 11 is held in contact with the work piece 11, and the frame 20 is held in contact with the work piece 11 in a direction opposite to the direction in which the work piece 12 is pressed, whereby the work piece 12 is pressed.
Is firmly abutted against the work 11. At this time,
Since no parts are located around the bottom of the work piece 12 that contacts the workpiece 11, there are no obstacles to welding, and welding can be performed completely without any problems. ..

When the welding is completed, the frame 20 is tilted to release the spring force of the spring 15, the pressing metal fitting 14 is straightened, and the spring connecting rod 19 is lowered and pulled out together with the pressing metal fitting 14.
Completely leave 11. In the above description, the object to be welded for mounting the caster is taken as an example, but the scope of application of the present invention is not limited to that case, and it is widely applicable to the work of fixing parts to the work under similar conditions. Is applicable to.

[Effect of device]

As described above, according to the present invention, it is possible to firmly hold a part such as a block with respect to a work such as a case without any obstacle around the part. It is possible to surely perform the work on the work and the parts concerned, and it is effective to shorten the work time.
