Description

Fluid pressure cylinder

This article is a fluid pressure cylinder, which can push the piston contained in the cylinder tube under the action of the pressure fluid supplied from a set of pressure fluid outlet and introduction ports, so that the piston rod connected to the piston performs linear reciprocating motion.

At the time of use, the pressure fluid is alternately supplied to the pressure fluid lead-out and introduction port to advance and retreat the piston inside the cylinder tube. Thereby, the piston rod will make a linear reciprocating motion along the axial direction of the cylinder tube.

The pressure flow system supplied to the cylinder chamber on the head cover side pushes the head cover side of the piston to extend the piston rod, and connects to the cylinder chamber on the rod cover side from the exhaust return port via a solenoid valve not shown in the figure. The pressure fluid flows into the cylinder chamber on the rod cover side through the lead-out and introduction port, and is reused to push the rod cover side of the piston to pull the piston rod into the cylinder tube.

This design is a derivative design of the No. 108301053 patent application.

The fluid pressure cylinder of this design has: a cylinder tube; a head cover provided at one end of the cylinder tube; a rod cover provided at the other end of the cylinder tube; extending parallel to the axis of the cylinder tube and connected to the head cover And the four tie rods of the rod cover; and the piston rod protruding from the rod cover (refer to the reference perspective view 1 showing the name of each part and the reference perspective view 2 showing the name of each part).

The cylinder tube system has a substantially octagonal cylindrical shape as a whole, and a cylinder chamber is arranged inside the cylinder tube. A piston (not shown) is housed in the cylinder chamber, and a piston rod is connected to the piston.

As shown in the A-A cross-sectional view with the internal mechanism omitted, the bulging part, which is located near the outer circumference of the cylinder tube and is parallel to a tie rod, has a substantially semicircular cross section and extends along the length direction. A flow path for reversible passage of pressure fluid is provided between the cylinder chamber on the rod cover side and the cylinder chamber on the head cover side partitioned by the piston.

The head cover and the rod cover are substantially rectangular parallelepiped, and in the head cover, a thin and circular protrusion is formed along the axis of the cylinder tube. On the other hand, the rod cover is provided with A thick cylindrical part that bulges in the axial direction of the cylinder tube.

A wide groove of the same shape is provided on one surface of the head cover and the rod cover. The head cover is provided with: a pressure fluid lead-out and inlet port communicating with the cylinder chamber on the side of the rod cover; a pressure fluid lead-out and inlet port communicating with the cylinder chamber on the head cover side; an exhaust return port for making the head cover side The pressure fluid in the cylinder chamber returns to the cylinder chamber on the rod cover side through a solenoid valve not shown; and a throttle valve for adjusting the flow rate of the pressure fluid for exhausting to the outside of the cylinder tube.

The feature of this creation is the overall shape of the "fluid pressure cylinder".
