Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a rail-based system that uses a desired number of manifold blocks installed along the rail. This invention relates to a manifold block fixing device for fixing to a manifold block.

0002

[Conventional technology]

Place the desired number of manifold blocks along the rail into a fixing block. The fixing device of the manifold Roblok, which is fixed to the rail by This is already known from the publication No. 136779. However, the above manifold block fixing device is not provided in the fixing block. Since these are attached to and detached from the rail using two tightening bolts, it is time-consuming to attach and detach them. Not only is it necessary to tighten the two bolts equally, but also to avoid uneven tightening. Tightening the bolts is troublesome because the bolts need to be tightened with

0003

[Problem that the idea aims to solve]

The problem that this invention aims to solve is a manifold that can be easily attached to and removed from the rail. The object of the present invention is to provide a block fixing device.

0004

[Means to solve the problem]

In order to solve the above problems, the present invention provides a rail along the rail having flanges on both sides in the width direction. Attach the desired number of manifold blocks to the rails using clamp fittings. In the manifold block fixing device that is fixed to the A fixing device that engages one of the above-mentioned flanges on the left and right legs and one leg that straddles the width direction of the rail. The clamp body has a hook, and the pusher is inserted between the left and right legs so that it can move up and down. It has a movable hook that engages the plate and the other side of the flange, and is pivotably supported on the clamp body. The hook lever is screwed onto the hook lever approximately in the widthwise center of the rail. The above-mentioned fixed hook and movable hook, and the rotation of the tightening bolt are provided. The holding plate moves by the manifold block by clamping the flange. The feature is that the rail is fixed to the rail.

[0005] In addition, in order to solve the same problem, we installed a spring that biases the movable hook in the opening direction. It's good to go.

[0006]

[Effect]

Engage the fixing hook of the clamp fitting with one side of the rail collar, and then tighten the clamp fitting. When attached to the rail from above and tightening the tightening bolt, the hook lever will rotate and the Rotate the movable hook to a position where it can engage with the other side of the collar, and move the presser plate to the rail. The fixed hook, movable hook, and presser plate hold the flange. , the manifold block is fixed to the rail by the clamp fitting. If you perform this operation in reverse, you can remove the clamp fittings and manifold block from the rail. You can leave. Therefore, the clamp fitting can be attached to and detached from the rail with a single tightening bolt. Attaching and detaching the clamp fittings to the rail to secure the manifold block is easy. In addition, since the tightening bolt presses the holding plate at approximately the center of the rail in the width direction, In addition, the tightening force becomes even and uneven tightening can be prevented.

[0007] Furthermore, since the movable hook is biased in the direction of opening by the spring, the clamp It is easier to attach and detach the tool to the rail.

【Example】

The figure shows an embodiment of the present invention, and this embodiment has flanges 1a and 1b on both sides in the width direction. A rail 1 having a structure, and a manifold block 2 continuously arranged along the rail 1. ・and the end plates 3, 3 and clamp covers 4, 4 attached to both ends thereof. A clamp fitting 5, which will be described later, is attached to the clamp cover 4.

[0009] The above-mentioned manifold block 2 is connected in series like a known manifold block. A supply flow path and a discharge flow path (not shown) and output ports A and B are provided, which communicate with each other. These channels and ports are connected to the corresponding valves 6 installed in each manifold block 2. The supply channel and the discharge channel communicate individually with the ports of the end plates 3, 3. It communicates with port P and discharge port R separately (see Fig. 2). Also, illustrations are omitted. However, like the clamp fitting 5, the manifold block 2 is not engaged with the flange 1a. It is also possible to provide an abutting portion that abuts the fixing hook, which will be described later, and the collar portion 1b.

0010 The clamp cover 4 has a recess that opens at the bottom and the front, and the clamp cover 4 is attached to the recess. The clamp body 8 of the clamp fitting 5 is made by bending a metal plate or the like into an inverted U shape. Legs 9a, 9a and legs 9b, 9b (all of which are in one piece) extend across the rail 1 in the width direction. (only one side is shown), it forms an inverted U-shape when viewed from the side, and the tips of the legs 9a, 9a are Fixed hooks 10, 10 that engage with the flange 1a are attached to the flange 1b at the tips of the legs 9b, 9b. Abutting portions 10a, 10a are respectively formed and are bent in an inverted U shape. The holding plate 11 has ends 11a, 11a guided by legs 9a, 9a and 9b, 9b. By doing so, it is inserted into the clamp body 8 so as to be movable in the vertical direction. The hook lever 14, which is pivotally connected to the clamp body 8 by a pin 13, is tilted when viewed from the front. Bent parts 14a, 14a bent in a U-shape, and an extension part 14b substantially perpendicular to the bent parts 14a, 14a. movable hooks 15, 1 that engage with the collar portion 1b at the tips of the bent portions 14a, 14a; 5 is formed, and a tightening bolt 16 is screwed onto the extension portion 14b. The movable hooks 15, 15 are biased in the direction of opening by the spring 17. Tighten again The attached bolt 16 is rotated to a position where the movable hooks 15, 15 can engage with the flange 1b. When the extension part 14b is screwed so as to be located approximately at the center of the rail 1 in the width direction. The head 16a is inserted into the center holes 19 and 2 of the clamp body 8 and the clamp cover 4. 0 and protrudes above the clamp cover 4.

[0011] In the above embodiment, a desired number of manifold blocks 2, . ・After connecting the end plates 3 and 3, the clamp attached to the clamp cover 4 The fixing hooks 10, 10 of the metal fitting 5 are engaged with the collar portion 1a of the rail 1, and this engaging portion is When the clamp fitting is rotated from above toward the rail, the contact portion 10a , 10a come into contact with the flange 1b and are positioned with respect to the rail 1 (see FIG. 1A). (see). In this case, the movable hooks 15, 15 are biased in the direction of opening by the spring 17. Therefore, positioning of the clamp fitting 5 with respect to the rail 1 is easy. Next, when the tightening bolt 16 is rotated in a predetermined direction, the tip of the bolt 16 is pressed. While pressing the plate 11 to move it downward in the figure, the extension part 1 of the hook lever 14 4b is moved upward, the fixed hooks 10, 10, movable hooks 15, 15 and presser The plates 11 sandwich the flanges 1a and 1b, and the manifold blocks 2,..., end Plates 3, 3, etc. are fixed to the rail 1 (see FIG. 1B). To remove manifold block 2, etc. from rail 1, perform the above operation. You can do it the other way around.

0012 The above attachment/detachment operation involves fixing the clamp fitting to the rail 1 with one tightening bolt 16. The operation is extremely simple. Also, the tightening bolt 16 is connected to the width of the rail 1. By pressing the presser plate 11 at approximately the center of the direction, the tightening force on the left and right sides is approximately equal. This will prevent you from tightening it unevenly.

[0013]

[Effect of the idea]

The manifold block fixing device of the present invention uses a single tightening bolt to secure the manifold block. The clamp fittings for fixing the Nifold block can be attached to and removed from the rail, so Easy to attach and detach. In addition, since the tightening force in the width direction is evenly distributed, it is possible to prevent uneven tightening of the manifold block. It is possible to prevent fluid leakage from the connecting surface of the pipe.

[0014] Furthermore, the hook lever is biased by a spring in the direction in which the movable hook is released. Therefore, it is easier to attach and detach the clamp fitting to the rail.
