Embodiment
The technical solution of the utility model is further described below in conjunction with the accompanying drawings, but claimed scope is not limited to
It is described.
It is can be seen that from Fig. 1 and Fig. 2 when installing gate throttle 5 on aero-engine or so hydraulic actuator pump housing, throttling
Door 5 need be arranged on more than 2 times of 5 length of gate throttle, 1.8 times of diameter relatively small deep hole in.If without specific purpose tool, it is difficult to
Gate throttle 5 is fast and accurately arranged in valve body 6.Similarly it also is difficult to gate throttle 5 from valve body 6 compared with being taken out in small deep hole.Such as
Fruit in the M4 screwed holes that are screwed on gate throttle 5 simply using screw by mounting and dismounting gate throttle 5, then gate throttle
5 in the hole of valve body 6 because to the rotary freedom of gate throttle 5 progress restriction, screw off screw after gate throttle 5 is installed
When, gate throttle 5 will rotate with screw, so screw can not be backed out.Equally when taking out gate throttle 5, it is necessary to be screwed into spiral shell
Nail, also because not carrying out restriction to the rotary freedom of gate throttle 5, gate throttle 5 can rotate with screw, and can not lead to
Cross and be screwed into screw to dismantle gate throttle 5.
By above-mentioned analysis, the specific purpose tool of the utility model design is as shown in figure 12, for realizing installation and removal section
Flow door 5.
When installing gate throttle 5, elastic jacket 1 is inserted in the second through hole of elastic jacket nut 2, then by gate throttle 5
The cylinder body regions of Φ 6 be encased in the Φ 6G7 holes of the first through hole of elastic jacket 1 and position, then turnable elastic chuck nut 2,
Gate throttle 5 is clamped (according to the mounting characteristic of gate throttle 5, the inner conical of elastic jacket nut 2 in the presence of the male-tapered face of trough of belt
Face uses the design of falling inner cone, the i.e. small Φ 6.5 in left end hole, the big Φ 8.6 in right-hand member hole), so reach fixed clamp limitation gate throttle 5 and revolve
Turn the purpose of the free degree, be fast and accurately arranged on gate throttle 5 in the relatively small deep hole of valve body 6 thereby using instrument.Installing
Reversely rotate elastic jacket nut 2 afterwards in place, be allowed to take out the installation that instrument completes gate throttle 5 after unclamping gate throttle 5.
When dismantling gate throttle 5, insert a tool into first in the hole of valve body 6, make the Φ 6G7 holes of the first through hole of resilient sleeve 1 with
The cylinders of Φ 6 positioning of gate throttle 5.Secondly turnable elastic chuck nut 2, similarly will throttling in the presence of the male cone (strobilus masculinus) of trough of belt
Door 5 clamps, and after limiting the rotary freedom of gate throttle 5, then knockout screw 3 is passed through into first through hole and is screwed into the M4 spiral shells of gate throttle 5
In pit, then while knockout screw 3 and elastic jacket 1 is pulled to take out gate throttle 5 from the hole of valve body 6 together.It is if only single
Gate throttle 5 solely is extracted using the clamping mode of elastic jacket 1, is just easy to that gate throttle 5 is pulled or can not taken.(this is due to
The clamping force of elastic jacket 1 causes skidding to pull gate throttle 5 less than pulling force), thus must use the clamping and positioning of elastic jacket 1 and
Knockout screw 3 cooperates together takes out gate throttle 5.
By above-mentioned principle Analysis, the utility model devises the throttling of a set of aero-engine or so hydraulic actuator
Door installation and removal specific purpose tool, including three parts, elastic jacket 1；Elastic jacket nut 2；Knockout screw 3.
Elastic jacket 1 is as shown in Figure 5 and Figure 6：
The left end of elastic jacket 1 is 20 ° of cones, cone end diameter Φ 7mm, outside diameter Φ 8.7mm, and first through hole is
The location fit Φ 6G7 using gap very little are accurately positioned very well, realize that inserting is freely accurately positioned.On 20 ° of cones
Wide 1.2mm, long 9mm grooves at (endoporus is Φ 6) symmetrical 4, so shrink in the presence of outer taper surface Φ 6G7 and reach folder
The purpose of tight gate throttle 5.Right-hand member is Φ 18X8mm exterior circular columns (processing of the first cylindrical face surface annular knurl), and endoporus is screwed hole
M4, and M12 external thread length 7mm, the total length of elastic jacket 1 are 45mm, material 40Cr, hardness HRC33~38, at surface
Haircut is blue.
Elastic jacket nut 2 is as shown in Figure 8 and Figure 9：
The structure of elastic jacket nut 2 is that left end designs for 20 ° of internal taper holes, i.e. the small Φ 6.5 in left end hole, the big Φ in right-hand member hole
8.6, the inner conical face of internal taper hole and the male-tapered face surface engagement of elastic jacket 2.Left end outside diameter Φ 11.3mm, length
15.5mm, the length of elastic jacket nut 2 are 28mm, and right-hand member is Φ 18X12.5 cylinders (at the second face of cylinder outer surface annular knurl
Reason) and M12 screwed holes reach 10mm, material 40Cr, hardness HRC33~38, surface treatment turn blue.
Knockout screw 3 is as shown in Figure 10 and Figure 11：
Knockout screw 3 is left end M4X8mm, length 81mm, material 40Cr, hardness HRC33~38, and surface treatment is turned blue,
Right-hand member connects ring-shaped handle.
