Description

A kind of moving platform symmetrical servo-cylinder of single rod
Technical field
The utility model relate to a kind of be applied to the multi-degree-of-freedom motion platform in dynamic simulant test field singly go out rod oil cylinder, especially a kind of moving platform symmetrical servo-cylinder of single rod.
Background technique
In many testing installations or control system, because the restriction of locational space restriction and physical dimension, the single-piston rod oil cylinder that size is shorter can only be used.Rod chamber and the rodless cavity area of single-piston rod oil cylinder are unequal, cause the ouput force of oil cylinder, movement velocity unequal, give and accurately control to bring comparatively burden.
Existing moving platform servo-cylinder is single rod servo-cylinder, adopts this structure to there is following shortcoming: 1, rod chamber and rodless cavity area unequal, motion control difficulty is larger; 2, two cavity areas are unequal, and servovalve opening needs frequent adjustment, and motion threshold state reversing impact can be caused large; 3, control program will be caused complicated especially for improving control accuracy, debugging cycle is long, and debugging cost is high.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of and controls the symmetrical servo-cylinder of the single rod of simple, elliptical gear is little, debugging cycle is short, cost is low a kind of moving platform.
For achieving the above object, the utility model adopts following scheme, the utility model comprises the front cover, cylinder barrel, the rear end cover that are fixedly connected sequentially, be arranged on the piston rod in front cover, cylinder barrel, its structure outline is that piston rod inner is provided with cavity, the front end of rear end cover is set to the end bar corresponding to piston rod inner cavity, and end bar and cavity inner wall form interior oil pocket, the outer oil cavity area equation that interior oil pocket area and piston rod and inner wall of cylinder, front cover surround; Oil circuit A on front cover is connected with outer oil cavity; Oil circuit B on rear end cover is connected with interior oil pocket.
Model utility beneficial effect
The utility model, by improving the structure of piston rod, forms the inside and outside oil pocket of two area equation, forms the symmetrical servo-cylinder of single rod; Adopt said structure that the utility model is had the following advantages: 1, inside and outside oil pocket area equation, simplifies control program, easily realize motion control; 2, inside and outside oil pocket area equation, servovalve is easy to control, and motion threshold state reversing impact is little, improves dynamic performance; 3, control program simplifies, and debugging cycle is short, realizes cost and reduces.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model comprises the front cover 2, cylinder barrel 7, the rear end cover 10 that are fixedly connected sequentially, be arranged on the piston rod 1 in front cover 2, cylinder barrel 7, piston rod 1 inside is provided with cavity, the front end of rear end cover 10 is set to the end bar 5 corresponding to piston rod inner cavity, end bar 5 constitutes interior oil pocket 4 with cavity, piston rod 1 outer wall and cylinder barrel 7 inwall, front cover 2 surround outer oil cavity 6, the area of interior oil pocket 4 and outer oil cavity 6 area equation; Oil circuit A 3 on front cover is connected with outer oil cavity 6; Oil circuit B 9 on rear end cover 10 is connected with interior oil pocket 4.Inside and outside piston rod 1 end, the working surface of both sides is provided with Sealing 8, and the inner side of front cover 2 and working surface are also provided with Sealing 8, fully ensure that interior oil pocket 4 area and outer oil cavity 6 area equation.Front cover 2, rear end cover 10 are also provided with Sealing 8 with the joint of cylinder barrel 7, avoid leaking of hydraulic oil.
During use, be connected with the joint bearing block on moving platform by the pin-and-hole 11 at the utility model two ends, oil circuit A 3 is connected with hydraulic oil pipe with oil circuit B 9, and carry out the bleeding of oil cylinder, according to the movement needs of moving platform, establishment control program, piston rod 1 to-and-fro motion.
