Description
Technical field
The utility model belongs to the extracting tool of aircraft accessory repair, and in particular to one kind being used for airline carriers of passengers accessory of hydraulic
Pump input shaft puller.
Background technology
At present in airline carriers of passengers attachment, hydraulic pump is important component.Its input is frequently encountered in repair procedures
Axis is stuck, it is not easy to directly decompose, need to decompose by auxiliary tool.Input shaft can directly choose under normal circumstances, but
It is that input shaft installation position is equipped with carbon and is sealed, if slightly error is easily damaged carbon envelope cooperation and influences sealing performance in choosing.Cause
This, can reduce the damage caused by other parts, while also ensuring that work is imitated to a certain extent using suitable tool
Rate.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of for airline carriers of passengers accessory of hydraulic pump
Input shaft puller, for decomposing aircraft accessory hydraulic pressure pump input shaft.
The purpose of this utility model is achieved through the following technical solutions：One kind is pumped for airline carriers of passengers accessory of hydraulic
Input shaft puller, including pull out set and be arranged and pulling out the loop bar that pulls out covered, the set that pulls out is made of identical two parts, pulls out set
It is respectively equipped with left extension bar, right extension bar on two parts, pulls out set and has been connected through a screw thread and pull out set nut, the set nut that pulls out passes through
Bearing is connected with positioning sleeve, and the positioning sleeve is equipped with to be held in position set and pull out the positioning for covering nut and not generating relative movement
Screw.
Preferably, one end of the every part for pulling out set is designed with external screw thread, the screw thread that two-part external screw thread is combined into
It is matched with the internal thread pulled out on set nut.
Preferably, the left extension bar, right extension bar and pull out loop bar be detachably connected.
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, at the same can according to the size of axis select not
Set is pulled out with internal diameter.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of the utility model；
Attached drawing 2 is to pull out nested structure schematic diagram；
Wherein, 1- pulls out set, the left extension bars of 2-, and 3- pulls out set nut, 4- positioning sleeves, 5- bearings, the right extension bars of 6-, and 7- pulls out set
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 to be used for airline carriers of passengers accessory of hydraulic pump input shaft puller, including pull out set 1, left extension bar 2,
It pulls out set nut 3, positioning sleeve 4, bearing 5, right extension bar 6 and pulls out loop bar 7；The set 1 that pulls out is connect by screw thread with set nut 3 is pulled out,
And pull out and connected by bearing 5 between set nut 3 and positioning sleeve 4, it is formed and is relatively rotated, while passing through the positioning spiral shell on positioning sleeve 4
Nail carries out relative positioning；The set 1 that pulls out is sub-assembly, is made of the identical part of two structures, set 1 will be first pulled out during use
It snaps on axis and then 3 part of set nut will be pulled out be inserted in and pull out set 1, then reached by rotating left extension bar 2, right extension bar 6 and pulling out loop bar 7
To purpose of choosing；It pulls out set 1 to be made of the identical two parts of structure, there is external screw thread in one end per part, is formed after two parts combination
Complete external screw thread, and pulls out the screw-internal thread fit on set nut 3, can be replaced according to out-of-alignment size when use various sizes of
Pull out set.It is described to rotate left extension bar 2, right extension bar 6 and pull out loop bar 7 as removable section, it can be lengthened according to service condition.
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.
