Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a clamping device, and more particularly to a device for clamping a casting flask, a pipe, or the like having a flange through the flange.

[Conventional technology]

When flanged frames such as casting flasks and pipes are stacked in several stages, it is necessary to connect the flanges together by some means. Bolt tightening or the like is used as a means for this, but a U-shaped clamp is often used as a simpler means. The manner in which this U-shaped clamp is used as a clamp for the flange of a casting flask will be explained with reference to FIG.

In Fig. 4, 1 is a U-shaped clamp, 5,
6 is a flask, 5a and 6a are flanges of the flasks 5 and 6, and 7 is a wedge.

When joining the flasks 5 and 6 by the flanges 5a and 5b, the flanges 5a and 6a were overlapped, the U-shaped clamp 1 was fitted as shown, and the flanges 5a and 6a were overlapped. Insert wedges from both directions into the gap between the thickness and the U-shaped clamp 1, and slide them in the directions of the arrows to remove the flanges 5a,
6a was fixed.

[Problem that the invention attempts to solve]

The means shown in FIG. 4 has the disadvantage that it takes time to prepare and set up because the U-shaped clamp and wedge are not integrated.

[Purpose of invention]

The present invention aims to overcome the above-mentioned drawbacks and provide a clamping device that can fix flanges with a single touch.

[Means for solving problems]

The present invention is a device for clamping two articles by the flanges of the articles, in which a fixing wedge is provided on the flange, a support plate is provided on the side of the article at the position of the fixing wedge, and the support plate is rotatably attached. This article clamping device is characterized in that it includes a letter-shaped clamp and a slide wedge at the position of the fixing wedge on the support plate.

That is, the present invention is novel in that the frame, the U-shaped clamp, and the wedge are integrated in order to solve the above problems.

[Effect]

An embodiment of the clamping device of the present invention is shown in FIG.
It is shown in FIG. 2 and its operation will be explained. Note that the first
2, the same reference numerals as in FIG. 4 indicate the same parts as in FIG. 3.

This clamp device consists of a U-shaped clamp 1, a fixed wedge 2, a slide wedge 3, and a support plate 4 that supports them from one or both sides. (Figures 1 and 2 show the support plate from one side.) The U-shaped clamp 1 can be rotated along the support plate 4, and the slide wedge 3 can be slid along the fixed wedge 2. It's getting old. From the unfixed state shown in FIG. 1, fixing is completed by rotating the U-shaped clamp 1 and driving in the slide wedge 3.
FIG. 2 shows the fixing completed state.

In the figure, reference numeral 4a denotes a square window provided in the support plate 4, into which the shaft 1a of the U-shaped clamp 1 is inserted so as not to come off. Further, 3a is a stopper for the slide wedge 3.

FIG. 3 shows another embodiment of the present invention,
This figure shows a case in which four clamping devices of the present invention are set when clamping a large flask. Since its configuration and operation are the same as those described above, a description thereof will be omitted.

[Effect of idea]

As mentioned above, the clamp device of the present invention is
In order to prevent the U-shaped clamp from coming off the product, it can be rotated 180 degrees on a support plate provided on the product, and a fixed wedge and a slide wedge are also provided on the support plate, making it possible to quickly and easily attach two The flanges of articles can be fixed.

[Brief explanation of the drawing]

FIGS. 1 to 3 are diagrams for explaining aspects of the present invention, in which FIG. 1 shows the state of the article (casting flask) before clamping, and FIG. 2 shows the state after clamping, respectively. FIG. 3 is a diagram showing a case in which a plurality of clamping devices of the present invention are provided for clamping large articles. FIG. 4 is a diagram showing a conventional clamp device. In Figures 1 to 3, 1 is a U-shaped clamp, 1a is coaxial, 2 is a fixed wedge, 3 is a sliding wedge,
3a is the same stopper, 4 is a support plate, 4a is a square window,
5 and 6 are casting flasks, and 5a and 6a are flanges.
