Abstract
The utility model relates to a motor sectional fixture of a direct drive electric-hydraulic servo valve, which is composed of a base (2) and a pull rod (1), the pull rod (1) is positioned and then is fixed on the base (2), a left magnetic conductor (4), a coil component (6), an armature component (5), a right magnetic conductor (7) and an alignment spring (8) are serially arranged, a back cover (9) is arranged for completion, the left and the right magnetic conductors are positioned by precise positions of the pull rod and the base, the back part of the pull rod is provided with a thread for positioning the position of the armature component, which is further regulated by a screw nut of a shaft of the armature component. The precise positioning of the pull rod of the motor sectional fixture of the direct drive electric-hydraulic servo valve can allow the armature component to be immediately pointed at the central position, thus having higher efficiency and ensuring the product quality.
Description
Technical field
The utility model belongs to direct drive type electro-hydraulic servo valve and makes the auxiliary equipment field, particularly relates to a kind of sectional fixture of direct drive type electro-hydraulic servo valve motor.
Background technology
The work of Direct Action Type servo valve is to utilize the size of electricity to control the size of high thrust motor thrust, promotes the displacement of spool, thus realize flow control.
The displacement of spool generally all about 1mm, so the armature of motor will about in the middle of two magnetic conductors and gap to about 1.5mm, also to be implemented in simultaneously and realize relative static conditions the centralizing spring equilibrium of forces under, so assemble up quite difficult.
Realize by hand tools that generally the armature adjustment is less than meta, and the cycle is very long, locating effect is also bad, has influenced the performance of direct drive type electro-hydraulic servo valve motor.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of direct drive type electro-hydraulic servo valve motor sectional fixture, has solved in the prior art armature adjustment less than the defective of meta.
Technical scheme
The utility model provides a kind of direct drive type electro-hydraulic servo valve motor sectional fixture, form by base and pull bar, described pull bar is fixed on the base the left magnetic conductor of packing in order, coil block behind the location, armature component, right magnetic conductor and centralizing spring, and the bonnet of packing into finishes, left and right sides magnetic conductor is located in the exact position of pull bar and base, the pull bar rear portion has screw thread to locate the position of armature component, regulates by the nut of armature component axle.
Described base and pull bar are fixed by screw.
Beneficial effect
The utility model can make the lost assembly of rank centring position immediately by the accurate location of pull bar, thereby higher efficient has been arranged, and has guaranteed the quality of product again.
Description of drawings
Fig. 1 structural representation of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 1, a kind of Direct Action Type servo valve motor contains protecgulum 3, left magnetic conductor 4, armature component 5, coil block 6, right magnetic conductor 7, centralizing spring 8, bonnet 9 and screw 10.Wherein, the left magnetic conductor 4 of motor and right magnetic conductor 7 are to embed in the coil block 6; Armature component 5 is by ball and centralizing spring 8 location, and drive end bearing bracket 3 and rear end cap 9 are built the back and be screwed in together with screw 10; Armature component one end of described motor is to contact with left magnetic conductor 4 by ball, and left and right sides magnetic conductor 4,6 embeds respectively in the circular coil 6, and the other end of armature component 5 is to be fixed on the centralizing spring 8, like this can the balance magnetic conductor to the attraction of armature.
A kind of direct drive type electro-hydraulic servo valve motor sectional fixture is made up of base 2 and pull bar 1.The wherein pull bar 1 of anchor clamps and base 2, back, described pull bar 1 location is fixed on the base 2 with screw, the left magnetic conductor 4 of packing in order, coil block 6, armature component 5, right magnetic conductor 7 and centralizing spring 8, and the bonnet 9 of packing into is finished, left and right sides magnetic conductor 4,6 is located in the exact position of pull bar 1 and base 2, and pull bar 1 rear portion has screw thread to locate the position of armature component 5, regulates by the nut of armature component axle.
