Abstract
The utility model provides an integrated servo actuator, which comprises a servo valve arranged on the actuator. The integrated servo actuator is fine in stability, the friction force between the actuator and the servo valve is small, and the service life of the servo actuator is prolonged.
Description
Technical field
The utility model relates to the servo actuator field, relates in particular to a kind of all-in-one-piece servo actuator.
Background technique
Servo actuator is the executive component in the electrohydraulic servo system, by load being applied controlled active forces such as pushing away, draw, realizes speed, direction, the displacement to load, the control of power.Servo actuator is made up of electrohydraulic control, actuator and sensor.Two parts that actuator in traditional servo actuator and servovalve formula are separated are carried out work with both sockets in using operation, such structure is not easy to safeguard, and the starting friction power between servovalve and the actuator is big, and frequency response is low; Frequent friction reduces the actuator life-span, influences the dynamic performance of servo actuator.
The model utility content
In order to solve existing technical problem in the background technique, the utility model proposes a kind of integrated type servo actuator, good stability, frictional force is little between actuator and the servovalve, has improved the life-span of servo actuator.
Technical solution of the present utility model is: a kind of integrated type servo actuator, comprise servovalve, and it is characterized in that: described servovalve is arranged on the actuator.
Above-mentioned integrated type servo actuator also comprises the switching piece, and described servovalve is connected with actuator by the switching piece.
Above-mentioned switching piece is the integrated form switching piece that the pipeline that servovalve is connected with actuator is all integrated.
The both sides of pipeline are provided with plug in the above-mentioned switching piece, and the two ends of described plug are provided with seal ring.
Above-mentioned integrated type servo actuator also includes piston rod, and described piston rod is provided with lining, and described lining is two, and two linings all are these special envelope sealings.
The guiding wear ring that vertically is provided with along lining is arranged on the above-mentioned lining, and described guiding wear ring is connected with piston rod.
Be the Glais ring sealing between above-mentioned piston rod and the servo actuator cylinder body, be provided with the guiding wear ring that guiding supports between piston rod and the cylinder body.
The utility model has the advantages that:
1) fixed form adopts the front end flange formula, and in the past flange plate and lining is integrated in one, and compact structure and body fixing also reliable is installed easily.
2) be provided with the earrings assembly in the piston rod end, can satisfy with the subordinate executive component and be connected fast, and connect reliable, convenient.
3) rear cylinder body is incited somebody to action the forced bolt jointing type that changes into of screw thread in the past, has simplified overall structure, and the processing of part and installation are all than convenient in the past.
4) piston rod adopts integrated type bidirectional piston bar, and there is identical service behaviour in actuator two chambeies.Simultaneously so that adopt built-in displacement transducer, the mechanical type protection of actuator can be set on the tube of back according to actual needs also.
5) being connected of actuator and servovalve adopted integrated form switching piece, actuator in the past must by pipeline could and on servovalve is connected, the structure more complicated, cost is also high, the while also easily causes vibrations, Installation and Debugging are also compared difficult.Integrated form switching piece is exactly that the pipeline that servovalve is connected with actuator is all integrated.Volume effect is little, the natural frequency height of actuator, and the while has also been simplified overall structure, the beautiful shape cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 (a) and Fig. 2 (b) are the seal form schematic representation of lining in the utility model.
Embodiment
Referring to Fig. 1, integrated type servo actuator of the present utility model comprises displacement transducer 1, rear cylinder body 2, back bush 3, plug 4, first seal ring 5, second seal ring 6, switching piece 7, servovalve 8, cylinder body 9, front lining 10, piston rod 11, earrings assembly 12, dust ring 13, this special envelope 14, seal ring 15, guiding wear ring 16 and Glais ring 18; Displacement transducer 1 is connected with piston rod 11 by rear cylinder body 2, front lining 10 and back bush 3 are socketed in respectively on the piston rod 11, servovalve 8 and actuator are integrative-structures, servovalve 8 is connected with actuator by switching piece 7, switching piece 7 is integrated form switching pieces that the pipeline that servovalve 8 is connected with actuator is all integrated, pipeline is all concentrated on the inside of switching piece 7, and servovalve 8 is connected work by the pipeline of switching piece 7 inside with actuator.Be provided with plug 4 in the both sides of pipeline, pipeline is carried out shutoff, the both sides of plug 4 also are provided with first seal ring 5 and second seal ring 6 in addition, and piston rod 11 ends are provided with earrings assembly 12, can satisfy with the subordinate executive component to be connected fast.
The front lining 10 of cylinder body 9 rear and front ends and the seal form of back bush 3 are referring to Fig. 2 (a) and Fig. 2 (b), front lining 10 and back bush 3 all adopt these special envelope 14 sealings of twice, vertical both sides of front lining 10 and back bush 3 also are provided with seal ring 15, the wear ring 16 that leads together leads, and two ends respectively are provided with dust ring 13.This special envelope of twice can guarantee that the interior leakage quantity of actuator is almost nil.Anti-extrusion performance well can not take place to be stranded presses phenomenon, and the little life-span of frictional force does not have creeping phenomenon when length starts.16 pairs of piston rods 11 of guiding wear ring have the supporting effect of accurately leading, and simultaneously, can prevent the Metal Contact between piston rod 11 and the lining, have reduced frictional force, guarantee that seal element is not damaged by radial force, prolong the life-span of servo actuator.Dust ring 13 makes extraneous dust and foul can not enter the oil pocket of actuator, thereby guarantees that fluid can not pollute, and has improved the service behaviour of actuator greatly.
Referring to Fig. 3, Glais ring is adopted in sealing between piston rod 11 and the cylinder body 9, also be provided with the guiding wear ring 17 that guiding supports between piston rod 11 and the cylinder body 9, guiding wear ring 17 has the supporting effect of accurately leading for the piston that moves, can absorb the radial force that produces at any time, guarantee that seal element is not damaged by radial force, prolong the life-span of servo actuator.Can prevent simultaneously the Metal Contact between piston and cylinder body or piston rod and the lining, reduce frictional force, phenomenon such as can not occur during startup creeping, and improved the stability of servo actuator work.
