Abstract
The utility model discloses a kind of valve seats to dismantle puller, including shaft and the extension bar that is arranged on shaft, shaft rod upper sleeve have clamp nut, transition sleeve, and shaft is threadedly coupled with clamp nut；Clamp nut is connected with top cover by thrust bearing, and the top cover has been connected through a screw thread nut, and nut, top cover and the transition sleeve axis centered on shaft are set gradually from outside to inside；Transition is set on the lower end of clamp nut, and the lower end of transition sleeve is connected with expansion set.The utility model can quickly and easily dismantle valve seat under the premise of not damaging other component, the work efficiency drop caused by tool equipment greatly reduced.
Description
Technical field
The utility model belongs to the extracting tool of machinery maintenance, and in particular to a kind of valve seat dismounting puller.
Background technology
At present in civil aircraft engine components, the valve seat in valve assembly is kept it in accordingly by spring
On position, when decomposition first spring force need to be overcome to take out valve body after further take out valve seat.It is between normal condition valve seat and valve body
The two gap being adjacent to is very narrow, very difficult using general utility tool decomposition, without the use of or using inappropriate tool
Shi Rongyi causes to damage to valve body and valve seat or external shell, while decomposition efficiency cannot also improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of valve seat dismounting puller, can be narrow
Valve seat is dismantled in space.
The purpose of this utility model is achieved through the following technical solutions：A kind of valve seat dismounting puller, including shaft
And the extension bar being arranged on shaft, the shaft rod upper sleeve have clamp nut, transition sleeve, shaft connects with clamp nut screw thread
It connects；The clamp nut is connected with top cover by thrust bearing, and the top cover has been connected through a screw thread nut, the nut, top
Set and transition sleeve axis centered on shaft are set gradually from outside to inside；The transition is set on the lower end of clamp nut, mistake
The lower end for crossing set is connected with expansion set.
Preferably, the top cover is equipped with hexagonal socket nut.
Preferably, the shaft end is pyramidal structure, and the expansion set is leaflet formula structure.
The utility model has the beneficial effects that：The utility model can be quick and convenient under the premise of not damaging other component
Dismounting valve seat, the work efficiency drop caused by tool equipment greatly reduced.
Description of the drawings
Attached drawing 1 is the general structure schematic diagram of the utility model；
Attached drawing 2 is expansion set connector schematic diagram；
Wherein, 1- clamp nuts, 2- thrust bearings, 3- top covers, 4- nuts, 5- expansion sets, 6- transition sleeves, 7- shafts, 8- add
Power bar.
Specific implementation mode
The technical solution of the utility model, but the scope of protection of the utility model are described in further detail below in conjunction with the accompanying drawings
It is not limited to as described below.
Embodiment
As shown in Figure 1, 2, a kind of valve seat dismantles puller, including clamp nut 1, thrust bearing 2, top cover 3, nut 4, expansion set
5, transition sleeve 6, shaft 7 and extension bar 8, the clamp nut 1, which is connect by screw thread with shaft 7, allows it to be axially moved；Pressure
Tight nut 1 is connect with top cover 3 by thrust bearing 2, when clamp nut 1 is axially moved, is convenient for axial force transmission to top cover 3,
Hexagonal socket nut in top cover 3 can keep top cover 3 and clamp nut 1 to be maintained at certain position, without generating to axial
Movement；The nut 4 is connected through a screw thread with top cover 3, can adjust the extension elongation of shaft 7；The transition sleeve 6 is compressing spiral shell
Female 1 lower end pushes expansion set 5 to make swollen toward the end conical surface movement of shaft 7 when clamp nut 1 moves down by transition sleeve 6
Set is expanded into forms tight fit with valve seat bore, can easily make the spring-compressed on valve seat by rotating extension bar 8 at this time
To achieve the purpose that dismounting.
The above is only the preferred embodiment of the utility model, it should be understood that the utility model is not limited to herein
Disclosed form is not to be taken as excluding other embodiments, and can be used for other combinations, modifications, and environments, and
Can be in contemplated scope described herein, modifications can be made through the above teachings or related fields of technology or knowledge.And this field
The modifications and changes that personnel are carried out do not depart from the spirit and scope of the utility model, then all rights appended by the utility model
It is required that protection domain in.
