Abstract
The present invention discloses a fixture used to adjust a valve housing position of a electrohydraulic servo valve which includes a component used to adjust valve housing, wherein a shoulder hole in one stage with its upside big and downside small is set on one end side of the servo valve; helical burr is set on lower hole wall face of the shoulder hole; the component that can adjust the valve housing includes an eccentric zero alignment pole with its external surface of top and bottom ladder-shaped and a tight nut that sleeved on the upper side of the eccentric zero alignment pole and pressed against the steps; the fixture includes a spanner component and a inner hexagon spanner; the spanner component is composed by a nut cover that can be placed inside the upper hole of the valve with a inner hexagon through hole on the end face that matches shape of outer surface of head of the tight nut and a handle that vertically connected to outer surface of nut cover; the inner hexagon spanner is inserted inside the hexagon blind hole of the eccentric zero alignment pole. The fixture that used to adjust valve housing position of an electrohydraulic servo valve is provided with advantages like simple structure, low production cost, easy usage, usage and reliable adjust result etc.
Description
Technical field
The present invention relates to a kind of displacement adjustment frock of precision parts, relate in particular to a kind of frock that is used to adjust electro-hydraulic servo valve housing position.
Background technique
Electrohydraulic control has experienced 50 years in the development of international professional domain, and the occasion of application also more and more widely.Yet the research of servovalve and manufacturing also are in a relatively backward state at home, the combine and assemble aspect of part, and technical merit is also very big with external gap.Housing position adjustment aspect for existing electrohydraulic control also exists problems and defective, and many part assemblings and debugging be difficulty relatively; Poor operability, particularly wherein the housing position of electrohydraulic control directly has influence on each performance quality of servovalve and client's acceptance level, and the result causes repetitive operation; Severe patient then causes part or parts to scrap; Waste of manpower, material resources, financial resources further then cause adverse effect to the entire product performance, after assembling if the test poor effect; Directly influence the overall performance of electrohydraulic control, influence productivity effect.
The assembly that one adjustment housing position is arranged on the valve body of servovalve; It is eccentric adjusting zero rod; The lower end of this off-centre adjusting zero rod is an eccentric cylinder; Also be with an assembly jack panel that plays fixing eccentric adjusting zero rod effect on the outer surface of upper of this off-centre adjusting zero rod, make the zero-bit of eccentric adjusting zero rod be in the desired position and will adjust eccentric adjusting zero rod.The assembly jack panel is laid down in the many employings of adjustment means of the housing position of electrohydraulic control earlier in the existing technology, adjusts eccentric adjusting zero rod again, and is not only time-consuming but also inaccurate like this.
Summary of the invention
The objective of the invention is to solve the problems referred to above that existing technology exists, a kind of easy to use, frock that the adjustment result accurately is used to adjust electro-hydraulic servo valve housing position is provided.
The objective of the invention is to be achieved: a kind of frock that is used to adjust electro-hydraulic servo valve housing position by following technological scheme; The assembly that comprises an adjustment valve pocket; One end face of said servovalve valve body is provided with a up big and down small one-level shoulder hole; The following wall surface of the hole of this shoulder hole is provided with screw thread, and the assembly of said adjustment valve pocket comprises that outer surface is that step-like eccentric adjusting zero rod and is sleeved on the top of eccentric adjusting zero rod and is resisted against the assembly jack panel on the step about in the of one, and the upper-end surface of said eccentric adjusting zero rod is provided with a cross section to be hexagonal blind hole and to be placed in the shoulder hole of valve body; The head cross section of said assembly jack panel is a hexagon and bar portion outer surface has the outside thread that is threaded with the following hole of valve body; Said frock comprises a wrench assembly and an inner hexagon spanner, wherein
Said wrench assembly can be placed in the last hole of valve body by one and end face be provided with one be vertically connected on the nut sleeve outer surface with the nut sleeve and of the interior hexagonal through hole of the form fit of the head outer surface of piecing together jack panel handle form;
Said inner hexagon spanner is plugged in the hexagon blind hole of eccentric adjusting zero rod.
The above-mentioned frock that is used to adjust electro-hydraulic servo valve housing position, wherein, the height of said nut sleeve is greater than the degree of depth in hole on the valve body.
The above-mentioned frock that is used to adjust electro-hydraulic servo valve housing position, wherein, said handle is connected the limit, upper end of the outer surface of nut sleeve.
The frock that is used to adjust electro-hydraulic servo valve housing position of the present invention has simple in structure, low cost of manufacture, easy to use, adjustment result accurately, advantage reliably.
Description of drawings
Fig. 1 frock user mode figure that is used to adjust electro-hydraulic servo valve housing position of the present invention.
Embodiment
Provide embodiment of the present invention below in conjunction with accompanying drawing:
See also Fig. 1, an end face of servovalve valve body 1 is provided with a up big and down small one-level shoulder hole 10, and following hole 101 walls of this shoulder hole 10 are provided with screw thread.The assembly of the adjustment valve pocket on the servovalve comprises an eccentric adjusting zero rod 2 and an assembly jack panel 3, and wherein, eccentric adjusting zero rod 2 is placed in the shoulder hole of valve body, and its outer surface up and down is a stepped shaft, and it is hexagonal blind hole 20 that its upper-end surface is provided with a cross section; Piece together jack panel 3 and be sleeved on the top of eccentric adjusting zero rod 2 and be resisted against on the step, its head 31 cross sections are hexagon and bar portion 32 outer surfaces have the outside thread that is threaded with the following hole 101 of valve body.
The frock that is used to adjust electro-hydraulic servo valve housing position of the present invention comprises a wrench assembly 4 and an inner hexagon spanner 5, wherein,
When the frock that is used to adjust electro-hydraulic servo valve housing position of the present invention is used; Install the assembly of adjustment valve pocket earlier, promptly eccentric adjusting zero rod 2 and is pieced together jack panel 3, then places wrench assembly 4; Nut sleeve 41 is entangled piece together jack panel 3; Grasp back handle 42 assembly jack panel 3 is not rotated, plant inner hexagon spanner 5 again in the hexagon blind hole 20 of eccentric adjusting zero rod 2, rotate the just also suitable and eccentric adjusting zero rod 2 of rotation of inner hexagon spanner 5; The eccentric cylinder of valve pocket is inserted in eccentric adjusting zero rod 2 lower ends will move left and right, so just can play the effect of adjusting housing position.Can access intact electrohydraulic control quickly and accurately according to designing requirement.
In sum, the frock that is used to adjust electro-hydraulic servo valve housing position of invention, have easy to use, the adjustment result accurately, performance reliably.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the present invention; And be not to be used as qualification of the present invention; The present invention can also change and more mode, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention the above embodiment's variation, modification.
