[0005]

[Action]

 When the base with the flow controller attached is attached to the fluid pressure actuator, or when the flow controller is attached to the base attached to the fluid actuator, the multiple communication passages and conduction paths provided in the base make it possible to connect the base with multiple input ports. A plurality of supply / discharge ports of the fluid pressure actuator communicate with each other via a flow rate regulator. Therefore, since the flow rate controller can be attached and detached regardless of the piping, it is easy to replace the flow rate controller. In addition, the solenoid valve installed on the base can supply and discharge the pressure fluid to and from the fluid pressure actuator.

Furthermore, since the communication between the plurality of conduction paths and the supply / discharge ports can be switched by changing the mounting attitude of the port switching plate, the connection of the pipe to the input port or the supply port can be changed. The driving direction of the fluid pressure actuator can be reversed.

The fluid pressure actuator 1 shown as a cylinder type actuator in the drawing has a body 2 having supply / discharge ports 7a and 7b which individually communicate with a pair of pressure chambers of the actuator 1, and the supply / discharge is performed through these ports. The pedestal 8 is configured to move back and forth by compressed air. However, the fluid pressure actuator of the present invention is not limited to the cylinder type actuator, but includes other fluid pressure actuators such as a vane type actuator.

The base 3 has input ports 10a and 10b, which are connected to compressed air pipes (not shown), on the surface facing the mounting surface 3a of the body 2 and is directly connected to the mounting surface 3a. The flow controller 4 is attached to one surface. Further, the base 3 includes communication passages 11a, 11b for individually communicating the input ports 10a, 10b with the inlet ports 15a, 15b of the regulators 4a, 4b constituting the flow rate regulator 4, and the outlet ports of the regulators 4a, 4b. 16a, 16b and the supply / discharge ports 7a, 7b are individually connected to each other, and the mounting portions 13 of the port switching plate formed in the openings of the mounting passages 3a, 12b. It is equipped (see Figure 2).

The flow rate controller 4 is configured such that the controllers 4a and 4b are integrally housed in the controller housing body 14, and between the inlet ports 15a and 15b and the outlet ports 16a and 16b. Check valves 17 and 17 and variable throttles 18 and 18 are arranged in parallel, respectively (see FIG. 2). Then, the check valve 17 permits meter-in control in which only compressed air is discharged to the fluid pressure actuator 1 as shown in the figure, or allows only compressed air to be supplied from a fluid pressure actuator (not shown). It can be either meter-out control.

Therefore, even if the connection of the piping to the input ports 10a and 10b is not changed, the driving direction of the fluid pressure actuator 1 can be reversed by reversing the mounting posture of the port switching plate 5 to the switching plate mounting portion 13. .

In the first embodiment, the flow rate controller 4 is attached to the base 3 by the mounting screws 22 and 22 via the gasket 23, the port switching plate 5 is incorporated into this assembly, and the mounting bolts 24 and 24 are attached.

The input ports 10a, 10b and the supply / drain ports 7a, 7b communicate with each other via the regulators 4a, 4b by 12a, 12b. When compressed air is supplied or discharged from the input ports 10a and 10b, the fluid pressure actuator 1 is driven, and the driving speed thereof can be controlled by increasing or decreasing the supply flow rate by the variable throttles 18 and 18 of the regulators 4a and 4b. . When replacing the flow rate controller 4, by removing the mounting screws 22 and 22, only the flow rate controller 4 can be removed regardless of the piping connected to the input ports 10a and 10b of the base 3. It is easy to replace the container 4. Further, when the port switching plate 5 is turned upside down and attached to the switching plate mounting portion 13 of the base 3, the driving direction of the fluid pressure actuator 1 can be reversed.
