Description
Technical field
The utility model belongs to a kind of servo-hydraulic integrated package, belongs to servo-hydraulic integrated block structure technical field.
Background technique
Three Degree Of Freedom analog platform hydraulic system is made up of a set of hydraulic station and two cover servo-cylinders.In order to improve reaction velocity, increase natural frequency, servovalve and oil-way integrated block must be installed on servo-cylinder.Although Three Degree Of Freedom analog platform profile is less, during due to electrohydraulic control no electric circuit, the locking state that mediates, the hydraulic fluid port of servo-cylinder is shut, and cannot realize and shake manually analog platform, and it is very inconvenient to debug and use.
Summary of the invention
The purpose of this utility model is to solve the technical problem that cannot manually shake analog platform in the time of no electric circuit that above-mentioned prior art exists, and a kind of servo-hydraulic integrated package that can manually shake Three Degree Of Freedom analog platform without startup oil sources is provided.
The utility model is achieved through the following technical solutions:
A kind of servo-hydraulic integrated package, its special way is to comprise the load oil circuit I 2 being installed on valve body 1, load oil circuit II 3, oil return circuit 4, load oil circuit I 2, load oil circuit II 3, the intersection of oil return circuit 4 is provided with the manually operated valve for controlling three oil circuit mutual conduction or closing, manually operated valve comprises the valve pocket 5 being installed on valve body 1, in valve pocket 5, be connected with valve rod 6, the below of valve rod 6 is provided with successively for realizing load oil circuit I 2, load oil circuit II 3 is conducted or the cone valve 7 of closing and for realizing load oil circuit I 2, the guiding valve 8 that oil return circuit 4 is conducted or closes,
The outer cover of described valve rod 6 is provided with O RunddichtringO 9, and the inwall of the outer wall of O RunddichtringO 9 and valve pocket 5 fits tightly;
The outer cover of described valve rod 6 is provided with the back-up ring 10 for preventing that O type circle lost efficacy, and back-up ring 10 is positioned at the top of O RunddichtringO 9;
The bottom of described valve pocket 5 is provided with the sealing gasket 11 for valve pocket 5 and valve body 1 are sealed mutually.
Servo-hydraulic integrated block structure of the present utility model is reasonable in design, be provided with the manually operated valve being conducted for controlling two load oil circuits and oil return circuit three, therefore the manual shake to Three Degree Of Freedom analog platform be can in the time that electrohydraulic control is not worked, realize, debugging and demonstration are convenient to.In sum, the utility model reasonable in design, easy to use, there is good application prospect.
Brief description of the drawings
Fig. 1: the structural representation of the manually operated valve of a kind of servo-hydraulic integrated package of the utility model in the time of closed condition;
Fig. 2: the structural representation of the manually operated valve of a kind of servo-hydraulic integrated package of the utility model in the time of opening state.
Embodiment
Provide embodiment of the present utility model below with reference to accompanying drawing, be used for the utility model to be described further.
Embodiment 1
A kind of servo-hydraulic integrated package of the present embodiment, comprise the load oil circuit I 2 being installed on valve body 1, load oil circuit II 3, oil return circuit 4, load oil circuit I 2, load oil circuit II 3, the intersection of oil return circuit III 4 is provided with the manually operated valve for controlling three oil circuit mutual conduction or closing, manually operated valve comprises the valve pocket 5 being installed on valve body 1, in valve pocket 5, be connected with valve rod 6, the below of valve rod 6 is provided with successively for realizing load oil circuit I 2, load oil circuit II 3 is conducted or the cone valve 7 of closing and for realizing load oil circuit I 2, the guiding valve 8 that oil return circuit 4 is conducted or closes.
Embodiment 2
The present embodiment and embodiment's 1 difference is: the outer cover of valve rod 6 is provided with O RunddichtringO 9, and the inwall of the outer wall of O RunddichtringO 9 and valve pocket 5 fits tightly; The outer cover of valve rod 6 is provided with the back-up ring 10 for preventing that O type circle lost efficacy, and back-up ring 10 is positioned at the top of O RunddichtringO 9; The bottom of valve pocket 5 is provided with the sealing gasket 11 for valve pocket 5 and valve body 1 are sealed mutually.
Working principle: in the time that needs manually shake Three Degree Of Freedom analog platform, only need rotary valve rod 6, make to move on valve rod 6, now, valve rod 6 drives on cone valve 7 and guiding valve 8 and moves, after moving on cone valve 7, load oil circuit I 2 and load oil circuit II 3 are conducted, after moving on guiding valve 8, make load oil circuit I 2 and oil return circuit 4 be conducted, thereby realize the mutual conduction of 4 of load oil circuit I 2, load oil circuit II 3, oil return circuit, now, oil cylinder is in free state, not limited by oil pressure, now can manually shake Three Degree Of Freedom analog platform, debug and demonstrate very convenient.
