Embodiment Construction

[0036] Hereinafter, preferred embodiments of the method for manufacturing the fluid pressure cylinder and piston assembly of the present invention will be described with reference to the drawings.

[0037] As an example of the fluid pressure device of the present invention, figure 1The fluid pressure cylinder 10A shown includes: a hollow cylindrical cylinder pipe 12 (main body), a head cover 14 arranged at one end of the cylinder pipe 12, a rod cover 16 arranged at the other end of the cylinder pipe 12, A piston unit 18 movable in the axial direction (direction of arrow X), and a piston rod 20 connected to the piston unit 18 are arranged in the housing 12 . The piston assembly 74 is constituted by the piston unit 18 and the piston rod 20 . This fluid pressure cylinder 10A is used, for example, as an actuator for conveyance of a workpiece.

[0038] The cylinder pipe 12 is made of a metal material such as aluminum alloy, and is formed of a cylindrical body extending in the axi...

Abstract

The fluid pressure cylinder (10A) has a cylinder tube (12), a piston unit (18) and a piston rod (20). The piston unit (18) has a piston body (38) consisting of a plurality of members and provided witha pad mounting groove (36). The piston body (38) has a first piston member (40) and a second piston member (42) axially laminated. And the pad mounting groove (36) is formed by a combination of at least two members. An excavating portion (46) having a depth in the axial direction is installed on one or both of the first piston member (40) and the second piston member (42).

Description

technical field [0001] The present invention relates to a fluid pressure device including a piston and a method of manufacturing a piston assembly. Background technique [0002] Conventionally, various devices are known as fluid pressure devices including a piston. For example, a fluid pressure cylinder having a piston displaced by a supply of a pressure fluid is known as a conveyance means (actuator) for a workpiece or the like. A general fluid pressure cylinder has a cylinder tube, a piston disposed in the cylinder tube so as to be movable in the axial direction, and a piston rod connected to the piston (see, for example, JP 2003-120602 A). In such a fluid pressure cylinder, when a pressurized fluid such as air is supplied into the cylinder tube, the piston is pushed by the pressurized fluid to displace in the axial direction, and the piston rod connected to the piston also displaces in the axial direction. [0003] However, a gasket mounting groove for mounting a gasket...
