Description

TECHNICAL FIELD

[0001] The utility model relates to a horizontal reciprocating bidirectional dragging oil cylinder. BACKGROUND

[0002] The common hydraulic cylinder is divided into rod cavity and rodless cavity, and in the horizontal installation state, the thrust generated when the rodless cavity is filled with oil is much greater than the pulling force when the rod cavity is filled with oil under the control of the same hydraulic oil source, and the axial movement speed of the piston rod when the rodless cavity is filled with oil is much smaller than the axial movement speed of the piston rod when the rod cavity is filled with oil, so the common hydraulic cylinder can directly meet the requirements of the common workbench with certain precision requirements for bidirectional horizontal movement. SUMMARY

[0003] The utility model discloses a horizontal reciprocating bidirectional dragging oil cylinder.

[0004] The utility model discloses a horizontal reciprocating bidirectional dragging oil cylinder, which comprises a piston and piston rod assembly 1, a guide sleeve assembly one 2, a screw one 3, a cylinder barrel assembly 4, a screw two 5 and a guide sleeve assembly two 6, characterized in that: the piston and piston rod assembly 1 is positioned on the inner hole of the cylinder barrel assembly 4, the inner hole of the guide sleeve assembly one 2 is positioned on the outer circle of the piston and piston rod assembly 1, one outer circle of the guide sleeve assembly one 2 is positioned on the inner hole of the cylinder barrel assembly 4 and is fixed by a plurality of screw one 3, the inner hole of the guide sleeve assembly two 6 is positioned on the outer circle of the piston and piston rod assembly 1, one outer circle of the guide sleeve assembly two 6 is positioned on the inner hole of the cylinder barrel assembly 4 and is fixed by a plurality of screw two 4, the guide sleeve assembly one 2 and the guide sleeve assembly two 6 are two same assemblies, the screw one 3 and the screw two 5 are also two same parts, the cylinder barrel assembly 4 is provided with a support 402, the piston and piston rod assembly is provided with a shaft pin hole one 101 and a shaft pin hole two 102 at both ends respectively, when the oil inlet one 401 of the cylinder barrel assembly 4 is filled with pressure oil, the piston and piston rod assembly 1 moves to the direction of the oil inlet two 403, and when the oil inlet two 403 of the cylinder barrel assembly 4 is filled with pressure oil, the piston and piston rod assembly 1 moves to the direction of the oil inlet one 401. Since the force area of the piston and piston rod assembly 1 is equal when oil is filled in two directions, the horizontal force and the horizontal bidirectional speed of the piston and piston rod assembly are equal and the thrust is constant in the full stroke under the action of the same oil source when being horizontally installed.

[0005] The utility model has the advantages that the horizontal force and the horizontal bidirectional speed generated when the oil cylinder moves horizontally are equal, and the control system is simplified.

[0006] The utility model will be explained in detail in connection with the drawings of the specification. BRIEF DESCRIPTION OF DRAWINGS
