Abstract
The invention discloses a dismounting tool for an end cap of an electro-hydraulic servo valve, which is a chuck slightly bigger than a semicircle. The end face of the dismounting tool is provided with two through holes with the diameter between those of a groove of a screw head of a mounted bolt and the screw head of the mounted bolt. Two of six mounting holes of the end cap corresponding to the two through holes are arranged in the same straight line. The end edge of the tool extends downward and the free end of the end edge is horizontally bent inward to form a radial groove. The free end of the end edge of the tool is clamped in the radial groove and allows the through holes on the end face of the tool to be communicated with the mounting holes. The dismounting tool for the end cap of the electro-hydraulic servo valve uses the close fit between the an inner groove on the body of the tool and the groove of end cap of the servo valve and dismount a bolt on the end cap to eject the end cap out and dismount the end cap. The tool has the advantages of simple structure, convenient use, no damages to the valve body and the end cap, and high working efficiency.
Description
Technical field
The present invention relates to a kind of dismounting frock of precision component, relate in particular to a kind of dismounting frock that is used for the electrohydraulic servo valve upper end cover.
Background technology
Electrohydraulic servo valve 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 servo valve 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.As the end cap of a vitals of RT7626M electrohydraulic servo valve, its dismounting bad will abrade, damage valve body or valve gap, thereby influence each item performance of whole valve, so the dismounting of the end cap on the valve body just seems and has been even more important.At present, for the RT7626M electrohydraulic servo valve, the dismounting of end cap is a difficult point always, requires to have higher location and outer symmetrically power of pulling out.Improperly will scratch and even damage valve gap or valve body if dismantle.
Summary of the invention
The objective of the invention is to solve the problems referred to above that prior art exists, provide a kind of and can improve the dismounting efficient of product and the dismounting frock that simple labour-saving is used for the electrohydraulic servo valve upper end cover.
The objective of the invention is to be achieved: a kind of dismounting frock that is used for the electrohydraulic servo valve upper end cover by following technical scheme; The longitudinal section of said end cap is the T font; On same diameter, be provided with six installing holes on its head end symmetrically; The head side of this end cap is provided with a radial groove; Be connected with valve body through the mounting screw that passes the interior hexagonal groove spiral shell head of having of these six installing holes in the locating hole of the bar portion insertion valve body of said end cap; Wherein, Said dismounting frock is one to be slightly larger than the chuck of semicircle, and its end face is provided with the through hole of two diameters between the spiral shell head diameter of the spiral shell head groove diameter of mounting screw and mounting screw, two installing hole settings that are positioned on the same diameter line in six installing holes that these two through hole respective ends cover; Extend downward vertically on the end limit of this frock and the inside level of its free end bends radially inside groove of formation one, and the end limit free end holding of said frock is in the radial groove of end cap and make the through hole on the frock end face be communicated with the installing hole on the end cap.
Owing to adopted the dismounting frock that is used for the electrohydraulic servo valve upper end cover of the present invention; What promptly this frock adopted is that frock inside groove and end cap groove closely cooperate; Come to the outer mutually power of end cap pair of balanced through the dismounting that is distributed in the screw on two symmetrical through holes on the same diameter; Stopped in the past because the end cap stuck phenomenon that causes with force unbalance, can improve dismounting, assembling, the maintenance efficiency and simply laborsaving of product.
Description of drawings
Fig. 1 is the user mode cutaway view that is used for the dismounting frock of electrohydraulic servo valve upper end cover of the present invention;
Fig. 2 is the user mode vertical view that is used for the dismounting frock of electrohydraulic servo valve upper end cover of the present invention.
The specific embodiment
Provide the specific embodiment of the present invention below in conjunction with accompanying drawing:
See also Fig. 1 and Fig. 2; The longitudinal section of electrohydraulic servo valve upper end cover 1 is the T font; On same diameter, be provided with six installing holes 100 symmetrically on its head 10 end faces; Head 10 sides of this end cap 1 are provided with a radial groove 101, are connected with valve body through the mounting screw 2 that passes the interior hexagonal groove 200 spiral shell heads 20 of having of these six installing holes 100 in the locating hole (not shown) of the bar portion 11 insertion valve bodies of end cap 1.
The dismounting frock 3 that is used for the electrohydraulic servo valve upper end cover of the present invention is one to be slightly larger than the chuck of semicircle; Its end face is provided with the through hole 30 of two diameters between spiral shell head 20 diameters of spiral shell head groove 200 diameters of mounting screw 2 and mounting screw 2; Two installing hole settings that are positioned on the same diameter line in six installing holes 100 on these two through holes, 30 corresponding end caps 1; Extend downward vertically on its end limit and the 31 inside levels bendings of its free end constitute an inside groove 32 radially, and end limit free end 31 holdings of this frock 3 are in the radial groove 101 of end cap 1 and the installing hole 100 that the through hole 30 on frock 1 end face is communicated with on the end caps 1.
The process of the dismounting frock dismounting end cap that is used for the electrohydraulic servo valve upper end cover of the present invention is: lay down for four of six mounting screws 2 that earlier end cap 1 are connected with valve body in advance; Keep two on the same diameter line; With frock 3 encapsulations of the present invention on end cap 1; The radially inside groove 32 of frock 3 is cooperated with the radial groove 101 of end cap, and the through hole 30 that passes frock 3 with two inner hexagon spanners simultaneously then inserts in the interior hexagonal groove 200 of spiral shell head 20 of mounting screws 2, through remaining two mounting screws 2 of the dismounting of inserting two inner hexagon spanner uniform balances in the through hole 30; Let mounting screw 2 spiral shell heads 20 head on frock 3 and outwards walk, thereby end cap 1 is pulled out.
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 variation, the modification of the above embodiment.
