Abstract

PURPOSE:To ease assembling work and prevent an accident due to wiring or piping of the apparatus on the output side, by providing a vane to one of a pair of bodies each having an installing surface, providing a stopper on the other body, and providing a cylindrical part, which opens to one side, at the axial central part on the other side together with placing the installing surfaces in such a manner that they turn their backs to each other and that they can be rotated. CONSTITUTION:A vane 5 is provided to one of bodies 1 and 2, while a stopper 7 is provided to the other body, being formed as integrated bodies, respectively. In this connection, installing surfaces 1b and 2b of the bodies 1 and 2 are placed in such a manner that they turn their backs to each other and the bodies 1 and 2 are assembled so that they can relatively be rotated. As a result, since a vane type oscillating actuator can be assembled like this, assembling work can be made simple. In addition, since the installing surfaces turn their backs to each other, the apparatus on the output side can directly be installed onto the installing surface of either one of the bodies 1 and 2. On the other hand, an installing surface 12a, which intersects the axial line of the second body 12 at a right angle, and a cylindrical part 12b, which opens to an installing surface 11b formed at the axial central part, are provided to the second body 12, so that wiring and piping for the apparatus on the output side can go through the cylindrical part 12b. Accordingly, the wiring or piping for the apparatus on the output side does not disturb the assembling work, and moreover a clear appearance can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a vane-type swinging actuator.

[Prior Art] Swing actuators are often equipped with fluid pressure devices such as fluid pressure cylinders, chucks, and valves on the output side. It is desirable that the other side be the mounting surface for the output side equipment and the output side equipment be directly mounted.

However, since the known swing actuator has a shaft passing through the body, it requires a coupling, a bearing link, etc. to attach and support the output side device.

Furthermore, since the wiring and piping of the output side equipment exposed to the outside are swung by the swiveling actuator, these not only obstruct the work but also may cause unexpected accidents.

[Problem to be Solved by the Invention] The problem to be solved by the present invention is to provide a vane-type swinging actuator to which an output side device can be directly attached.

[Means for Solving the Problems] In order to solve the above problems, the vane type swing actuator of the present invention has a pair of bodies provided with mounting surfaces that can be rotated relative to each other with the mounting surfaces facing each other. The assembly is characterized in that a vane is integrally formed on one of the pair of bodies, and a stopper is integrally formed on the other.

In addition, in order to insert the wiring, piping, etc. of the output side equipment, there is an axial opening in the axial center of one body on the mounting surface of the other body. It is preferable to provide a cylindrical portion.

[Operation] A swing actuator can be constructed by assembling a pair of bodies in which a covane and a stopper are integrally formed, with their mounting surfaces facing away from each other. Since the output side equipment is directly attached to one of the mounting surfaces facing the other side, the output side equipment can be constructed as a block.

Further, since the fluid pressure that drives the swing actuator acts in the axial direction, it is possible to counteract the axial load of the output side equipment.

Furthermore, the wiring and piping of the output side equipment are not exposed to the outside by being inserted through the cylindrical part provided at the axial center of the body, so they do not get in the way of work and the appearance is clean. Moreover, since the cylindrical portion is provided at the axial center where the torque of the vane is small, the decrease in torque due to the installation of the cylindrical portion can be reduced.

[Embodiment] Figures 1 to 3 show a first embodiment of the present invention, and this vane type swing actuator has a recess 1a that is open in the axial direction, and a mounting surface that is perpendicular to the axis on the opposite side of the opening. 1b

a second body 2 that covers the opening of the four parts 1a;
A cover 3 is provided on the outer periphery of the first body 1 for assembling the bodies 1 and 2 so as to be relatively rotatable.

The first body 1 includes a vane 5 integrally projecting from the outer wall of the recess 1a toward the axis, and bearings 8 disposed on both sides of a flange 1c formed integrally with the outer wall.
The second body 2 is rotatably connected to the cover 3 by 6, and the second body 2 is provided with a stopper 7 that is integral with the body and partitions the recess 1a, and is fitted with an appropriate bolt or the like (not shown). It is attached to the cover 3 by a member with the mounting surfaces 1b and 2a facing away from each other, and the stopper 7
A seal packing 7a is attached to the first body 1, and a seal member IO is attached to the relative sliding surfaces of the first body 1 and the vane 5 and the second body 2.

The recess 1a is divided into a pair of drive chambers 8a and 8b by the vane 5 and the stopper 7, and the second body 2

9 have been established.

Although not shown, a stopper may be provided on the first body l and a vane may be provided on the second body 2, and
A plurality of vanes 5 and a plurality of stoppers 7 may be provided.

In the first embodiment, the vane 5 is installed on one of the bodies 1 and 2,
Since the stopper 7 is integrally formed on the other side, when the mounting surfaces 1b and 28 of the bodies 1 and 2 are placed facing each other so that they can rotate relative to each other, a vane-type swinging actuator is assembled, so assembly is easy. .

Furthermore, by arranging the mounting surfaces 1b and 2a to face each other, the output device can be directly mounted on one of the mounting surfaces. When one body is fixed by the other mounting surface and pressure fluid is supplied to the drive chambers 8a and 8b, the output side equipment can be rotated and oscillated. In this case, even if an axial force from the output device acts on the actuator, the drive chamber 8a
, 8b can be counteracted by the acting force of the fluid pressure supplied to them.

In the second embodiment, the wiring and piping of the output side equipment can be inserted through the cylindrical portion 12b of the second body 12, so the wiring and piping of the output side equipment not only do not interfere with the work. , the appearance can be made cleaner. Further, since the cylindrical portion 12b is provided at the axial center portion of the vane 5 where the torque is small, the reduction in torque due to the formation of the cylindrical portion 12b can be reduced.
