Abstract
The utility model relates to an actuator cylinder with a terminal function. The actuator cylinder comprises a piston rod 1, an end cover 2 and a cylinder body 3, wherein the terminal of the actuator cylinder is provided with a cylinder 4, a piston tip 6 is matched with the cylinder 4 at the terminal of the actuator cylinder, the cylindrical wall of the cylinder 4 is provided with throttling holes, and the throttling holes are multiple thin and long-strip-shaped throttling grooves 5 being parallel to the axis of the cylinder 4 and extending to the bottom of the cylindrical wall of the cylinder 4, or multiple throttling holes distributed along the axis direction. The actuator cylinder with the terminal function is simple in structure, variable throttling can be realized through the terminal, and has a relatively good buffering effect so that the use reliability and the service life of the actuator cylinder and equipment can be effectively improved.
Description
Technical field
The utility model belongs to the hydropneumatics field, relates to a kind of pressurized strut with terminal function.
Background technique
For the needs heavy load; The equipment of high-speed motion pressurized strut; Speed can be undergone mutation when traditional pressurized strut moved to end, will be to pressurized strut and other hydraulic system annexes destruction that impacts, the operational safety and the life-span of having reduced pressurized strut itself and other hydraulic system annexes.Existing pressurized strut with terminal pooling feature, its structure are that the end of pressurized strut has a cylinder, and the piston termination cooperates with the terminal cylinder of pressurized strut, has circular orifice in cylinder barrel bottom.This kind pressurized strut is in movement process, and the throttle orifice effect is constant, and is undesirable for the equipment cushioning effect of heavy load, high-speed motion pressurized strut.
The model utility content
The utility model technical problem to be solved is: a kind of pressurized strut that better has terminal pooling feature is provided, effectively improves the operational safety and the life-span of pressurized strut and equipment itself.
The technological scheme of the utility model is: a kind of pressurized strut with terminal function; Comprise piston rod 1, end cap 2, cylindrical shell 3; The end of said pressurized strut has a cylinder 4; The terminal cylinder 4 of piston termination 6 and pressurized strut cooperates, has throttle orifice on the barrel of cylinder 4, it is characterized by: said throttle orifice is some and cylinder 4 parallel axes and the elongated strip shaped throttling groove 5 that extends to cylinder 4 barrels bottom or along some throttle orifices 7 of axial direction distribution.
The beneficial effect of the utility model is: the utility model is simple in structure, and through terminal variable restrictor, cushioning effect is better, can effectively improve the operational safety and the life-span of pressurized strut and equipment itself.
Description of drawings
Fig. 1 is the structural representation that the utlity model has a kind of preferable embodiment of pressurized strut of terminal function;
Fig. 2 is the structural representation that the utlity model has the another kind of embodiment of pressurized strut of terminal function;
Wherein, 1-piston rod, 2-end cap, 3-cylindrical shell, 4-cylinder, 5-throttling groove, 6-piston termination, 7-throttle orifice.
Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
Referring to Fig. 1, the utlity model has a kind of embodiment of the pressurized strut of terminal function, comprise piston rod 1; End cap 2; Cylindrical shell 3, the end of said pressurized strut have a cylinder 4, and piston termination 6 cooperates with the terminal cylinder 4 of pressurized strut; Have throttle orifice on the barrel of cylinder 4, it is characterized by: said throttle orifice is some and cylinder 4 parallel axes and the elongated strip shaped throttling groove 5 that extends to cylinder 4 barrels bottom.
During normal the use, high pressure oil gets into the pressurized strut rod chamber from ozzle A, promotes piston rod 1 motion, and oil return is flowed out from ozzle B.When piston termination 6 gets in the cylinder 4; Fluid in the cylinder 4 flows into rodless cavity through throttling groove 5 under the effect of pressure; Pressure in the cylinder 4 and cylinder 4 outer return pressures produce pressure difference, and piston termination 6 is produced reaction force, have suppressed the movement velocity of piston rod 1 with piston termination 6.Further motion along with piston rod 1; Flow through throttling groove 5 diminishes; Restriction effect improves, and makes cylinder 4 inside and outside differential pressures become big, and it is big that the reaction thrust of piston termination 6 becomes; Make the piston rod 1 and the movement velocity of piston termination 6 become slower, further reduced the impact failure of piston rod 1 with the 6 pairs of pressurized strut end caps in piston termination and other hydraulic system annexes.
Referring to Fig. 2, compare with a kind of embodiment of the utility model shown in Figure 1, change elongated strip shaped throttling groove 5 into distribute some throttle orifices 7 along axial direction, can reach the purpose of terminal variable restrictor equally.
