Description

[Detailed Description of the Invention] This invention relates to a mounting member for a hydraulic actuator.

For the installation of a hydraulic actuator, for example a hydraulic rotary servo actuator, the parts are shown in Figure 1a as an example.
The configuration is as shown in , l).

In Fig. 1 a, l), A is a hydraulic rotary servo actuator, and B is a hydraulic rotary servo actuator A which is mounted and held on a mount C as an example. The parts are shown.

According to this example, the hydraulic rotary servo actuator A has a casing 4 which externally consists of three members 1, 2 and 3, and an oil coupler 5 is overlapped and coupled to one side of the casing 4. An oil supply cap 6, an oil drain cap 7, a drain cap 8, etc. for a hydraulic power source (not shown) are arranged on the oil coupler 5, and the output shaft 10 of the rotary servo actuator A is connected to the casing 4. The servo input shaft 11 is made to protrude to the surface 9 side, and the servo input shaft 11 is made to protrude to the opposite side, so that an output corresponding to the input from the output shaft 10 is obtained by servo human power applied to the servo input shaft 11 from, for example, a pulse motor. It's Nishide.

In the case of the bracket type mounting, the mounting surface 9 of the hydraulic rotary servo actuator A is fixed to the member B with appropriate bolts 12 or the like.

In this way, in the conventional means, the hydraulic rotary servo actuator A is connected to an external hydraulic power source through the oil filler cap 6, oil drain cap 7, and drain cap 8 provided on the oil coupler 5 attached thereto. Therefore, the dimensions and weight of hydraulic rotary servo actuator A itself have to be large, and therefore, it is necessary to attach it to member B.
They were large in size, shape, and weight, and required a lot of space to install.

The purpose of this invention is to improve the conventional inconveniences as mentioned above.In particular, as mentioned above, without using an oil coupler etc., the installation target is supplied to the surface, and the oil drain port, drain port, etc. An effective mounting applied to a hydraulic actuator with each opening is a member, and the mounting is a member that includes a supply hole, an oil drain port, a drain port, etc. within the member for guiding each opening to an external hydraulic power source. By forming oil passageways such as , oil drainage, and drains, the hydraulic actuator itself can be made substantially smaller and lighter.As a result, installation can be done by reducing the size and weight of the parts themselves, and by taking up less space. It is possible to promote savings and diversification of installation.

Examples of this invention are shown below in the attached drawings Figures 2 to 4 a.
, l) will be explained.

In these embodiments, the applied hydraulic actuator D has the oil supply port 2 on the surface 20 to which it is attached, as described above.
1. The hydraulic rotary servo actuator with the oil drain port 22 and the drain port 23 open is applied, and this hydraulic rotary servo actuator D is attached with a pulse motor E for giving servo input thereto. To treat/do as such.

The embodiment shown in FIG. 2 is an example in which the member F is attached to an arm structural member of an industrial robot, for example, and the hydraulic rotary servo actuator D is used in the joint part of the arm structural member. is the member body 24
A surface 25 is provided for mounting on the main body side, and a surface 20 is provided for mounting the hydraulic rotary servo actuator D, and the oil fill port 21 and oil drain port 22 are provided inside the main body.
Oil passages 26 and 27 for oil supply and oil drainage are formed to guide the oil to an external hydraulic power source (not shown).

In addition, the embodiment shown in Figure 3a, 1) is an example in which the mounting is applied to the bracket as the member F, for example, for general use such as machine tools, and this mounting is also applied to the bracket. Also, the body side mounting on the member 28 is on surface 2.
9, the hydraulic rotary servo actuator D
In addition to attaching the surface 20 appropriately, the oil filler port 21, oil drain port 22, and drain port 23 are installed inside the main body.
Oil supply cap 33.33 to external hydraulic power source, oil drain cap 34.3
4 and drain pipes 30, 30, 31, 31 and 3 for oil supply, oil discharge and drain leading to the drain cap 35
2 was formed.

In this example, two sets of oil passageways and oil drainage passages for oil supply and oil drainage are provided, but only one of them is used as required, and the other is sealed and used.

Furthermore, the embodiment shown in Fig. 4a and l) is an example in which the attachment is applied to the body G when there is a restriction on the direction of the attachment screw, and the attachment is applied to the member F. In addition, the member body 36 is provided with a surface 37 for mounting on the main body side, and the surface 20 is appropriately attached to the mounting surface of the hydraulic rotary servo actuator D.
Inside the main body is the oil filler port 21. Connect the oil drain port 22 and the drain port 23 to an external hydraulic power source using the oil supply cap 41. Oil drain cap 42
Also, oil passages 38, 39, and 40 for oil supply, oil discharge, and drain leading to the drain mouthpiece 43 are formed.

Therefore, as described in detail in each of the embodiments above, when this invention is used, the hydraulic actuator is mounted by forming an oil passage in the member that connects the actuator with an external hydraulic power source. This actuator has the functions of mounting the main body and a conventional oil coupler, and there is no need to provide any special means such as an oil coupler to this actuator, which reduces the weight and size of the actuator itself, and saves installation space. , it has features such as being able to provide diversity in piping for oil passage, expanding the scope of application to the actuator system, and greatly contributing to reducing the size and weight of the entire system.
