Abstract

[Use of the item]; This item is a fluid pressure cylinder that 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 inlet ports, so that the piston rod connected to the piston moves in a straight line The reciprocating action. ; During use, the pressure fluid is alternately supplied to the pressure fluid lead-in and lead-out port to make the piston inside the cylinder tube move forward and backward. As a result, the piston rod will make a linear reciprocating motion along the axis 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 is connected from the exhaust return port to the cylinder chamber on the rod cover side through a solenoid valve not shown in the figure. The pressure fluid outlet and inlet port flows into the cylinder chamber on the rod cover side, and is again used to push the rod cover side of the piston and pull the piston rod into the cylinder tube. ;[Design Description];This design is a derivative design of patent application No. 108300696. ; The fluid pressure cylinder of this design article 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; a piston rod protruding from the rod cover; and a piston rod installed at the front end of the piston rod Nut (refer to the reference perspective view 1 showing the names of each part and the reference perspective view 2 showing the names of each part). The cylinder tube is generally in the shape of a rectangular parallelepiped, and a cylinder chamber is provided inside the cylinder tube. A piston (not shown) is accommodated in the cylinder chamber, and a piston rod is connected to the piston. As shown in the A-A line reference cross-sectional view showing the names of each part, a cylinder chamber is provided inside the cylinder tube to allow the pressure fluid to reversibly pass between the cylinder chamber on the rod cover side and the cylinder chamber on the head cover side separated by the piston. flow path. ;There is a sensor installation groove on one side of the cylinder tube. A wide groove is provided on the remaining three sides of the cylinder tube, and a sensor mounting groove is provided inside the wide groove. The head cover and the rod cover are roughly rectangular in shape, and on the one hand, the head cover has a thin, circular protrusion along the axis of the cylinder tube, and on the other hand, the rod cover has a protrusion along the cylinder tube. A thick cylindrical portion that bulges in the axial direction. ; One side of the rod cover is provided with: a sensor installation groove; a pressure fluid outlet and inlet port connected to the cylinder chamber on the rod cover side; a pressure fluid outlet and inlet port connected to the cylinder chamber on the head cover side; exhaust return The port is used to return the pressure fluid in the cylinder chamber on the head cover side to the cylinder chamber on the rod cover side through the solenoid valve (not shown); and the throttle valve is used to adjust the pressure fluid that is exhausted to the outside of the cylinder tube. of flow. ; A sensor installation groove and a buffer pin are provided on one side of the rod cover. ; The remaining three sides of the head cover and rod cover are provided with grooves of the same shape and wide, and a sensor installation groove is provided inside the wide groove. ;The characteristic of this creation is the overall shape of the "fluid pressure cylinder".
